Latin jazz orchestra Essay -- essays research papers

If I were to use one word to describe the â€Å"Afro-Latin Jazz Orchestra† that word would be astonishing. At first, hearing that I was required to attend a Jazz concert I was completely turned off. I am very closed minded and automatically thought to myself that the kind of music would be dreadful. That is not the case anymore. This genre of music is amusing and very pleasing to the ears. The band members are some of the most talented musicians that I ever saw or heard.   Ã‚  Ã‚  Ã‚  Ã‚  Standing room tickets were sold out when we arrived at Mc Carter Theater. For ten dollars we purchased box seats right near the stage. My friend Kevin and I were thrilled with our seats which allowed the beat view of the whole stage. The theater it self was beautiful. The stage was set up well with nice a nice lighting. The entire band consisted of eighteen musicians. There were seventeen males and one female. In the front of the stage was the pianist and director Arturo O’ Farril. Also in the front was the musician on bongos. To the left of the stage was the saxophone players and to the right the trombone players. In the rear were the trumpet players with the musician on bass in front of them as well as the drummer. I believe this setup allowed for their superb sound. Over all our seats were incredible and made the performance much more enjoyable.   Ã‚  Ã‚  Ã‚  Ã‚  Between songs the pianist and director Arturo O’ Farril would give a short introduction and history behind ...

Ruling Ideologies :: essays research papers

Core Studies 3 Casilda Adames Take-Home Exam November 16, 1999 The ruling ideology dealing with welfare is a negative view among the majority of Americans. It states that welfare recipients are lazy people who have lots of children and collect checks for a long period of time. This statement is believed mostly among higher-class people because they feel that if they can work hard for their money, welfare recipients can do the same, and not live off other people’s money. Charles Murray supports the statement â€Å"welfare policies encourage poor women to have more children† in one of his books, but is proven wrong by careful studies and demographics. It has been studied that welfare has almost no effect on bearing children. These studies show that younger women are more likely to be poor and their poverty makes their children poor. American adults by far are more unequal in wealth and income than any other industrial society as well as the declining incomes of young men since the mid-1970s. Many young men cannot afford to keep their children out of poverty or decide not to the handle the duties or responsibilities of marriage, leaving young mothers and children even poorer, leading them to depend on welfare. According to a New York Times article dated 2/29/92, there are fewer children receiving assistance from welfare and are not just being lazy but and collecting checks, but actually getting off welfare. This ruling ideology that most of the American society supports leads to the lack of wide political support and budget-cutting of means-tested programs. These mean-tested programs are available only to those people who can prove that they are poor. Only Social Security and Medicare, both Universal programs, have largely survived cutbacks in recent years because it is widely accepted throughout the American society. The reason it is accepted in the American society is that everybody contributes to social security and everybody benefits from it. As stated before many people in the American society do not want to support the welfare people because they are perceived to be lazy bums, who just collect checks and have lost of children, which persuades people’s attitudes to not support these means-tested programs including welfare. AFDC has been repeatedly cut and will continue to decline as long as federal governments transfer responsibility for welfare to state governments which aids the American’s ideology that help to the poor must be â€Å"limited, conditional and unpleasant† so that people get off welfare and acquire jobs.

Coral Reefs Need Help Essay -- Environment, Oceans, Fish

Beautiful beaches, a hot sun, glistening sand, and a clear ocean would make the perfect vacation, right? Many of us would enjoy being somewhere tropical. This kind of vacation won’t last much longer if we don’t start taking care of endangered coral reefs now! World government leaders should establish laws to protect them. People may ask, â€Å"If coral reefs are in such danger, why don’t we fix the problem since they provide benefits for the whole world?† Frankly, it’s not that simple. Protecting endangered coral reefs will provide the whole world with long lasting benefits. To figure out how to solve the problem, we must start with the benefits they provide for humans and nonhumans. Coral reefs support 128 corallivorous fish species, one third of which feed almost solely on coral (80%) (Cole 286). These reefs also provide the corallivorous fish species like butterfly fish with shelter and living space (Cole 287). Most of these fish feed on Scleractinian coral (â€Å"hard† coral) while the others feed on â€Å"soft† coral due to regional variation (Cole 288, 292). For the balance of fish and coral reefs to remain in sync, the feeding intensity of the fish and the regeneration of coral reefs need to balance one another (Cole 297). When combined with other stressors like pollution and coral bleaching, it’s hard for the reefs to recover (Cole 299). Since so many people rely on the fish caught around these reefs, limiting stress on them is important. They supply the benefit and necessity of food to many people. In developing countries, c oral reefs contribute to one fourth of the fish caught that feed about one billion people in Asia alone (Moore 1). Fish seem to be plentiful, at least right now. Much of the world’s poor population depends on fis... ...urces like water. Citizens can also help by taking showers instead of baths, buying locally grown foods, carpooling, walking, or bicycling. Citizens need to collaborate and motivate one another when it comes to using less fossil fuel. Fixing this issue will certainly be difficult, but we can adjust our lifestyles in a way that’ll keep the environment safe for coral reefs. Human, nonhuman and coral reef health is likely to improve! Paying to save coral reefs will be more beneficial to the world, and international governments should share the cost to protect the reefs. People who pollute more than regulations allow should be fined with that money going towards the maintenance of coral reefs. Food, life-saving medicine, income from tourism, and coastal protection will all diminish if we don’t start helping today!

METHODS OF INVESTIGATION 1. 1 IntroductionKnowledge of the structure of sound system and its articulatory and acoustic characteristics is very important in teaching and learning foreign languages. The teacher has to know the starting point from which to begin teaching; he must be able to point out the differences between the pupil’s mother tongue and the language to be learnt. He should be able to choose adequate training exercises. That’s why it is vital to know, at least, the basic principles of this science. The term â€Å"phonetics† comes from the Greek words meaning â€Å"sound or matters pertaining to voice†. What does phonetics study?It is concerned with the human noises by which the thought is actualized (that is the oral aspect of speech communication). However phon etics takes the content level into consideration too. Only meaningful sound sequences are regarded as speech and phonetics is concerned only with such sounds which are carriers of organized information of a language. Phonetics analyses the nature of these sounds, their combinations and their functions in relation to the meaning. No kind of linguistic study can be carried out without constant consideration of the material on the expression level.Consequently, phonetics is important in the study of a language. An understanding of it is a basis for any adequate understanding of the structure or functioning of a language. It follows from this that phonetics is a basic branch – many would say the most fundamental branch of linguistics, because it gives a language a definite form. The vocabulary and grammar of a language can function only when the language has a phonetic form. So grammar and vocabulary depend on phonetics, they cannot exist outside of phonetics, because all lexical and grammar phenomena are expressed phonetically.Neither linguistic theory nor linguistic description can do without phonetics and is complete without it. Phonetics, being a branch of linguistics, occupies a peculiar position. On the one hand it serves as a means of expressing grammatical and lexical phenomena. On the other hand it has laws of its own which are independent of grammar and vocabulary. Besides it is closely connected with a number of other sciences, such as physics, biology, physiology, psychology etc. The more phonetics develops the more various branches of science become involved in the field of phonetic investigation.Phonetics is not a new science. It was known to the ancient Greeks and to the ancient Hindus. The scientists of that time were concerned with speech sounds only. It may be said that the orthography of all written languages which use alphabets developed in the course of a very detailed phonetic analysis. Nevertheless, phonetics as an independent science began to develop only in the 19th century, before that it used to be a part of grammar. There has been considerable progress and growth in the 20th century. New concepts, methods of investigation, new theories and schools have been developed.Not only has the sphere of investigation in phonetics become wider, but several new branches of phonetics have also arisen. So our further point will be made on the branches and divisions of phonetics. 1. 2 Branches and Divisions of Phonetics Everyone who starts learning a foreign language first of all is introduced into practical or normative phonetics. It studies the material form of phonetic phenomena in relation to meaning. It teaches how to pronounce sounds correctly and what intonation to use to convey this or that meaning or emotion. It is called normative because we are to teach the â€Å"norm† of English pronunciation.Theoretical phonetics is mainly concerned with the functioning of phonetic units in the language. It discusses t he problems of phonetics in academic terms and gives a scientific approach to the phonetic theory. Other two important branches of phonetics are special and general phonetics. Special phonetics may be subdivided into descriptive and historical. Special descriptive phonetics is concerned with the study of the phonetic structure of one language only in its static form, synchronically and the domain of special historical phonetics is the phonetic structure of a language in its historical development, diachronically.Historical phonetics is part of the history of a language. Its aim is to trace and establish the successive changes in the phonetic system of a given language at different stages of its historical development. It is very important for the study of the modern phonetic system because without a historical approach it is impossible to understand how this modern phonetic system has developed and what further changes it is likely to undergo.General phonetics studies all the sound- producing possibilities of the human speech apparatus and the ways they are used for purposes of human communication by means of language, it finds out what types of speech sounds exist in various languages of the world, how they are produced and what role they play in forming and expressing thoughts; it also determines the nature, types and role of other phonetic means, such as word stress and intonation.General phonetics is based on the material which the special phonetics of a great number of languages provides; it also uses data of other sciences: physics, biology, psychology, speech pathology, etc. So it makes a number of general conclusions concerning the complex nature of speech sounds, analyses phonetic phenomena from different points of view and formulates phonetic theories. On the one hand general phonetics is based on the data of special phonetics; on the other hand it provides valuable theoretical material which enables us to understand and to interpret correctly differe nt phonetic phenomena of concrete languages.Another important division is into phonology and phonetics. According to the conception of the Prague Linguistic School phonetics and phonology are two independent branches of science, phonetics is a biological science which is concerned with the physical and physiological characteristics of speech sounds, and phonology is a linguistic science which is concerned with the social functions of different phonetic phenomena. Another term for this branch is functional phonetics. The father of Phonology is Prince Nicholas Trubetskoi.His work â€Å"Fundementals of Phonology† separates phonetics and phonology, saying that they are not related and that phonetics is not part of linguistics, but a biological science that deals only with the physiological aspect of speech sounds. Nevertheless it doesn't seem logical to separate function from phonetic forms, thus excluding phonetics from the linguistic sciences. So nowadays most phoneticians cons ider both phonetics and phonology part of linguistics. Phonetics itself is subdivided into 3 sub branches, each dealing with special aspects of sounds, their production by a speaker and perception by a listener.Phonetic processing starts on a neurophonetic level, in the brain of a speaker, where the formation of the concept takes place. The human brain controls the behaviour of the articulatory (or speech) organs and makes them move in a particular way. The branch of phonetics which is concerned with the study of speech sounds as regards their production by the human speech organs is called articulatory (physiological) phonetics. In other words it deals with the way human organs join to produce sounds.Articulatory basis of a language is a set of articulation tendencies characteristic for a particular language community, so articulatory gesturing is culturally specific and not universal. Different articulations produce different acoustic effects, or different speech sounds. Consequen tly, speech sounds have a second aspect, a physical or, more exactly, an acoustic one, which constitutes the domain of acoustic phonetics. Acoustic phonetics involves knowledge of physics as it deals with the physical property of sounds. Any sound is a pressure disturbance transmitted through an elastic medium.When articulatory gesturing starts it causes disturbance (a sound wave) in the medium, which is transmitted from one particle of the medium to another and is reproduced as a sound wave travels from the source to the listener. Perceptual or auditory phonetics is concerned with the way our auditory mechanism works to process speech information. There is a boundary line between reception (which doesn't involve understanding) and perception (which involves decoding and understanding). Phonetic perception is a product of sensation and interpretation of speech elements which take place in a human brain.Phonetics is also divided into two major components: segmental phonetics, which i s concerned with individual sounds (â€Å"segments† of speech) and suprasegmental phonetics whose domain is larger units of connected speech: syllables, words, phrases and texts. There are a number of other divisions of phonetics. We may speak about comparative phonetics whose aims are to study the correlation between the phonetic systems of two or more languages and find out the correspondences between speech sounds and intonation structures.Its data are extremely useful in teaching and learning a foreign language as they show differences and similarities of the phonetic systems of two or more languages and predict possible difficulties for the learners. It should be mentioned that the most difficult phonetic phenomena are those absent in the mother tongue. For example, the sounds [? -? ] cause a lot of difficulties for the Russian students of English, as there are no sounds with similar articulations in the Russian language.On the other hand the most stable and persistent p ronunciation mistakes are made in those phenomena which are similar in the two languages but not exactly the same. For example, falling intonation. In English it goes to the very bottom of the voice, while in Russian it is not so steep and it does not reach the same low note as in English. The data of applied phonetics are essential for practical purposes in speech therapy and logopedia. It helps to correct speech defects and to teach deaf-mutes (or people who do not speak as a result of an accident or some disease) to speak.Experimental phonetics deals with research work which is carried out with the help of different technical devices, machines for measurements and for instrumental analysis. Phonetics as a whole and all of its branches have not come into being all at once: they developed gradually, and their development was closely connected with and determined by the development of other branches of linguistics and other sciences. 1. 3. Phonetics and Social Sciences So our furthe r point should be made in connection with the relationship between phonetics and social sciences. Language is not an isolated phenomenon; it is a part of society.No branch of linguistics can be studied without taking into consideration at least the study of other aspects of society. In the past two decades we have seen the development of quite distinct interdisciplinary subjects, such as sociolinguistics (and sociophonetics correspondingly), psycholinguistics, mathematical linguistics and others. As their titles suggest, they are studied from two points of view and thus require knowledge of both. Sociophonetics studies the ways in which pronunciation functions in society. It is interested in the ways in which phonetic structures vary in response to different social functions.Society here is used in its broadest sense, it includes such phenomena as nationality, regional and social groups, age, gender, different situations of speaking – talking to equals, superiors, on the â₠¬Å"job†, when we are trying to persuade, inform, agree and so on. The aim of sociophonetics is to correlate phonetic variations with situational factors. It’s obvious that these data are vital for language learners who are to observe social norms and to accommodate to different situations they find themselves in. One more example of interdisciplinary overlap is the relation of linguistics to psychology.Psycholinguistics covers an extremely broad area, from acoustic phonetics to language pathology, and includes such problems as acquisition of language by children, memory, attention, speech perception, second-language acquisition and so on. Phonosemantics studies the relations between the sound structure of a word and its meaning. There is some data proving that the sounds that constitute a word have their own â€Å"inner† meaning, which causes certain associations in the listener’s mind. For example, close vowels produce the effect of â€Å"smallness†, and voiceless consonants sound more â€Å"unpleasant† and â€Å"rude† than their voiced counterparts, etc.Some sounds are associated with certain colours. These data may be helpful in teaching, for example, â€Å"tying† together the sound structure of a word and its meaning, thus facilitating the process of memorising new words. Scientists have always been interested how children acquire their own language without being taught. They hope that these data might be useful in teaching grown-up people a foreign language, too. Pragmalinguistics is a comparatively new science, which studies what linguistic means and ways of influence on a hearer to choose in order to bring about certain effects in the process of communication.Correspondently the domain of pragmaphonetics is to analyse the functioning and speech effects of the sound system of a language. Phonetics is closely connected with a number of other sciences such as physics (or rather acoustics), mathematics, biology, physiology and others. The more phonetics develops the more various branches of science become involved in the field of phonetic investigation. Phonetics has become important in a number of technological fields connected with communication.Phoneticians work alongside the communication engineers in devising and perfecting machines that can understand, that is respond to human speech, or machines for reading aloud the printed page and vice versa, converting speech directly into printed words on paper. Although scientists are still dissatisfied with the quality of synthesized speech, these data are applied in security systems, answering machines and for other technical purposes. 1. 4. Methods of Phonetic Investigation Methods applied in investigating the sound matter of the language have changed greatly with the development of technology and computer science.From the beginning of phonetics the phonetician has relied mainly on what he could feel of his own speech and on what h e could hear both of his own and the informant’s speech. Such methods are called direct and consist in observing the movements and positions of one's own or other people's organs of speech in pronouncing various speech sounds, as well as in analysing one's own kinaesthetic sensations (muscle tense) during the articulation of speech sounds and in comparing them with the resultant auditory impressions.Investigation by means of this method can be effective only if the persons employing it have been specially trained and have acquired considerable skills in associating the qualities of the perceived sound with the nature of the articulations producing it. Instrumental methods were introduced into phonetics in the last century to supplement the impressions deriving from the human senses. These methods are based upon registering or computing machines and technical devices, such as spectrograph, intonograph, x-ray photography and cinematography, laryngoscope and some others.The intr oduction of machines for measurements and for instrumental analysis into phonetics has resulted in their use for detailed study of many of the phenomena which are present in the sound wave or in the articulatory process at any given moment. These techniques can be very useful both for discovering in detail how English speakers produce their speech sounds, and for demonstrating to learners of English their pronunciation. Computers can provide additional pronunciation training, displaying useful information on the screen and being a powerful visual aid for effective phonetic practice.One more advantage of the modern experimental study of speech is the enormous amount of varied spoken speech data stored on computers. It facilitates the process of looking for cross-language differences and similarities. The data obtained from instrumental analysis supplement and verify those obtained by means of direct observation, thus making the research results more detailed and precise. II. THE ARTI CULATORY CHARACTERISTIC OF THE ENGLISH SPEECH SOUNDS 2. 1. The Anatomo-mechanical Aspect of Sound Production Speech is impossible without the speech mechanism.So now our attention will be focused on the articulatory aspect of speech sounds. Speech sounds are acoustic effects of the articulatory movements and positions of the human speech organs. The immediate source of speech sounds is the human speech mechanism developed and perfected in the process of the historical development of man. The organs of speech are the object of linguistic investigation mainly from the point of view of the functions they perform in speech production. So before analysing the linguistic function of phonetic units we need to know how the speech mechanism acts in producing oral speech.According to their main sound-producing functions the speech organs can be roughly divided into the following four groups: the power mechanism (lungs, diaphragm, windpipe, bronchi), the vibrator mechanism (larynx, vocal cords , glottis), the resonator mechanism (nasal and mouth cavities) and the obstructer mechanism (tongue, lips, hard and soft palate, teeth). From the lungs through the wind-pipe the air-stream passes to the larynx, containing the vocal cords. The opening between the vocal cords, through which the air passes, is called the glottis. The linguistic function of the vocal cords onsists in providing the source of energy necessary for speech production. When the vocal cords are kept wide apart (i. e. the glottis is open) the air passes between the cords and the result is non-phonic breath. Then the vocal cords may be drawn together tightly, so that air cannot pass between them. The sudden opening of the glottis produces an explosion resembling a short cough; this sound is called the glottal stop. It often occurs in English when it reinforces or even replaces the sounds [p], [t], [k] or even when it precedes the energetic articulation of vowel sounds.The most important role of the vocal cords i s their participation in the production of voice. The effect of voice is achieved when the vocal cords are brought loosely together, creating an obstacle to the air stream; when the air pressure becomes very strong the air forces its way between the vocal cords thus making the, vibrate. When, as is usual, these vibrations are regular, they produce vocal tone, or voice, whose pitch depends on the frequency of vibrations. We are able to vary the speed of vibration of our vocal cords and thus to change the pitch.Conscious variations of pitch are responsible for intonation. We are also able to modify the size of the puff of the air which escapes at each vibration, thus changing the amplitude of the vibration, which corresponds to the loudness of the sound heard by a listener. The air-stream, having passed through the vocal cords, is now subject to further modification, according to the shape of the pharynx, mouth and nasal cavities. The direction in which the air-stream will follow from the pharynx depends on the position of the soft palate.When it is lowered, the pharynx opens into the nasal cavity. When it is risen, the air-stream comes to the mouth cavity. As in the mouth cavity a lot of movable speech organs are situated it can easily change its shape, thus forming the majority of speech sounds. The movable (or active) speech organs, situated in the mouth cavity are: the tongue, the soft palate with the uvula, the lips and the lower jaw. Of all the movable organs within the mouth cavity the tongue is the most flexible and active.For convenience, the surface of the tongue or divided into several parts: the most flexible part of the tongue, which normally lies opposite the teeth ridge, is called the blade, the tip of the tongue being its extreme point. The part of the tongue next to the blade is called the front of the tongue. Then come the back and the root of the tongue. The tongue being the most active speech organ in the mouth cavity, the main principles of the majority of articulatory classifications of vowels are based on the movements and positions of the tongue. 2. 2. The system of English VowelsThe movements of the body of the tongue provide a convenient articulatory basis for classifying vowels according to two principles: 1) horizontal and 2) vertical movements of the tongue. According to the horizontal movement five classes of English vowels are distinguished. They are: 1) front [i:], [e], [e? ], [ ], [? ] 2) front-retracted [? ], [ ] 3) central [? ], [? :], [? ], [ ], [a? ], [a? ] 4) back [? ], [? :], [u:], [a:], [ ] 5) back-advanced [? ], [ ] Not all phoneticians single out the classes of front-retracted and back-advanced vowels. So both [i:] and [? vowels are classed as front, and both [u:] and [? ] – as back. The point is that the vowels in these two pairs differ in quality which is partially due to the raised part of the tongue. So in this case a more detailed classification seems to be a more precise one, since it adequately reflects the articulatory distinctions actually present in the language. Now let's view another articulatory characteristic of vowels, which is based on the vertical movement of the tongue. The way phoneticians of different schools approach this aspect is also slightly different.Some scholars distinguish three classes of vowels: high (or close), mid and low (or open) vowels. But to mark all significant changes in vowel quality it is not enough to single out these three groups of vowels. For instance, both English vowels [i:] and [? ] belong to the group of close vowels, but when the vowel [? ] is articulated the front of the tongue is not so high in the mouth as it is in the case of the vowel [i:]. Russian phoneticians made the classification more detailed distinguishing two subclasses in each class: broad and narrow variations of the 3 vertical positions of the tongue.Thus the following 6 groups of vowels are distinguished: 1) close a) narrow [i:], [u:] b) broad [? ], [? ], [ ], [ ] 2) mid a) narrow [e], [? :], [? ], [e? ], [ ] b) broad [? ], [? ] 3) open a) narrow [ ], [? :], [ ] b) broad [? ], [a? ], [a? ], [? ], [a:]. In addition to the above-mentioned principle of the classification of vowels phoneticians suggest five other criteria: 1) stability of articulation 2) lip position 3) character of the vowel end 4) length 5) tenseness The stability of articulation specifies the actual position of the articulating organ in the process of the articulation.There are two possible variants: a) the tongue position is stable, in this case the articulated vowel is pure, it consists of one element and is called a monophthong; and b) the tongue position changes, in this case a vowel consists of two elements, the first one is strong, it is a nucleus, the second element is very weak – it is a glide. There exists a third variety, when the change in the tongue position is fairly weak, in this case the articulated vowel is not pure, but it still consists of one element, such vowels are called diphthongoids.So according to this principle the English vowels are subdivided into: a) monophthongs [? ], [? ], [e], [? :], [? ], [? ], [? :], [? ], [? ], [a:] b) diphthongs [ ], [ ], [e? ], [ ], [ ], [a? ], [a? ], [ ] c) diphthongoids [i:], [u:] Some phoneticians, however, do not share this way of thinking and do not distinguish diphthongoids. But for the learners of English it is important to know this differentiation as it is useful for teaching purposes. Besides in modern English the tendency for diphthongization is becoming gradually stronger. Another feature of English vowels is lip rounding.Traditionally three lip positions are distinguished: spread, neutral and rounded. In English lip rounding is not relevant phonologically (it means that no two words can be distinguished on its basis). Our next point should be made about another characteristic of English vowels. It's checkness. The quality of all English monophthongs in the stressed pos ition is strongly affected by the following consonant. If a stressed vowel is followed by a strong (fortis) voiceless consonant it is cut off by it. In this case the end of the vowel is strong and the vowel is called checked.If a vowel is followed by a weak (lenis) voiced consonant or by no consonant at all the end of it is weak. In this case the vowel is called free. Now it should be useful to consider another articulatory characteristic of English vowels, that is their length or quantity. The English monophthongs are traditionally divided into short [? ], [e], [? ], [? ], [? ], [? ], [? ] and long ones [i:], [a:], [? :], [? :], [u:]. It should be noted that vowel length or quantity has for a long time been the point of disagreement among phoneticians. The problem is whether variations in quantity are meaningful (relevant) or not.Let's look at the pairs of words: [b? d – bi:d], [s? t – si:t]. Are they distinguished from one another by the opposition of different lengt h (that's the approach of D. Jones, an outstanding British phonetician) or is the difference in quality (or in other words the position of the active organ of speech) decisive here? Most Russian phoneticians are in favour of the second conception. They state that a feature can be systemic if it does not depend on the context. As to the length of English vowels, it varies and depends on a lot of factors, the first being phonetic context.The shortest are vowels followed by voiceless consonants and the longest are in free position. For example in â€Å"meat† [i:] is half as long as the [i:] in â€Å"me†, but may approximately have the same duration as the [? ] in â€Å"mid†. But still these words â€Å"mid† and â€Å"meat† are perceived as different words because the vowels are different in quality. So no matter what time is required for the articulation of these vowels, the main distinctive feature is quality, not quantity. As for tenseness we shall only mention that special instrumental analysis shows that historically long vowels are tense, and historically short ones are lax.To sum it up we may conclude that among all the articulatory features of English vowels only two are relevant: the stability of articulation and tongue position. 2. 3. The System of English Consonants Before passing on to the classification of English consonants the difference between consonants and vowels should be considered. Acoustically consonants are noises, not musical tones like vowels. From the articulatory point of view the difference is due to the work of speech organs. In case of consonants various obstructions are made. As to the classification of English consonants there are few ways of seeing the situation.One of them is the classification according to the type of obstacle. On this ground two large classes of consonants are distinguished: 1) occlusive, which are produced when a complete obstruction is formed: [t, d, p, b, k, g], [m, n, ? ]; 2) constrictive, which are produced when an incomplete obstruction is formed: [s, z, f, v, O, ? , ? , ? , h], [w, r, l, j]. Each of the 2 classes is subdivided into noise consonants (these are those in the production of which noise prevails over tone) and sonorants (in the production of which tone component prevails).Noise occlusive consonants are called stops because the air stream is completely stopped at some point of articulation and then released with an explosion, that is why they are also called plosives: [t, d, p, b, k, g]. Constrictive noise consonants are called fricatives, because the air escapes through the narrowing with friction: [s, z, f, v, O, ? , ? , ? , h]. Occlusive-constrictive consonants or affricates are noise consonants produced with a complete obstruction which is slowly released and the air stream escapes from the mouth with some friction. There are only two affricates in English: [? ,? . Other phoneticians suggest that the first and basic principle of clas sification should be the degree of noise. So consonants are divided first into noise consonants and sonorants and then each group is divided into smaller groups. Another very important principle is the place of articulation. According to this principle English consonants are classed into labial, lingual and glottal. I. Labial consonants in their turn are subdivided into a) bilabial (produced when both lips are active) [w, m, p, b]; b) labio-dental (articulated with the lower lip against the edge of the upper teeth) [f, v]. II.Among the class of lingual consonants three subclasses are distinguished: a) forelingual; b) medio-lingual; c) back-lingual. Forelingual consonants are also of three kinds: 1) apical (articulated with the tip of the tongue) [t, d, s, z, O, ? , ? , ? , ? , ? , n, l]. 2) dorsal (produced when the blade of the tongue is active). There are no dorsal consonants in English. In Russian these are the sounds [?, ?, ?, ?, ?, ?, ?, ?]. 3) cacuminal (articulated with the t ip of the tongue curled back). There is only one cacuminal consonant in English – [r]. According to the place of obstruction forelingual consonants may be: – interdental, rticulated with the tip of the tongue projected between the teeth: [O, ? ]; – dental, produced with the blade of the tongue against the upper teeth: the Russian [?, ?, ?, ?, ?, ?]; – alveolar, produced with the tip of the tongue against the upper teeth ridge: [t, d, s, z, n, l]; – post-alveolar, articulated with the tip or the blade of the tongue against the back part of the teeth ridge: [r]; – palato-alveolar, made with the tip or the blade of the tongue against the teeth ridge and the front part of the tongue raised towards the hard palate, thus having two places of articulation (two foci): [? ? , ? , ? ]. b) mediolingual consonants are produced with the front part of the tongue raised high to the hard palate, so they are always palatal: [j]. c) backlingual consonants are also called velar, because they are produced with the back part of the tongue raised towards the soft palate: [k, g, ? ]. III. The glottal consonant [h] is articulated in the glottis. There are no glottal consonants in Russian. One more articulatory characteristic which should be mentioned is the position of the soft palate.According to this principle consonants may be oral and nasal. There are only three nasal consonants in English, which require the lowered position of the soft palate: [m, n, ]. The rest of the consonants are oral because in their production the soft palate is raised and the air escapes through the mouth. Our next point will be made in connection with another sound property, that is voice-voiceless characteristic. When the vocal cords are brought together and vibrate we hear voice and the consonants are voiced: [b, d, g, v, z, ? , ? , ? . When the vocal cords are apart and do not vibrate we hear only noise and the consonants are voiceless: [p, t, k, f, s, O, ? , ? ]. It should be noted that the difference between such pairs as [p, b], [t, d] and so on is based not only on the absence or presence of the voice component, as voiced consonants are not fully voiced in all word positions, in word final position, for example, they are partially devoiced. There's also energy difference. All voiced consonants are weak or lenis and all voiceless consonants are strong or fortis.Summing it up, it should be mentioned that the most important articulatory features, which could serve as a criterion for grouping consonants into functionally similar classes, are: type of obstruction; place of articulation and the active organ of speech; force of articulation. The rest of the characteristics are considered to be irrelevant, as they are of no importance from the phonological point of view, but they provide necessary and useful information for teaching purposes. It is for this reason that they are normally included into the classification. III.THE ACOUSTIC AND AUDITORY ASPECTS OF THE ENGLISH SPEECH SOUNDS The auditory aspect of any sound is inseparable from its acoustic aspect and acoustic phonetics is closely connected with auditory phonetics and both may, therefore, be considered together. Objectively sound is a physical phenomenon, a kind of moving energy generated by some vibrating body. Subjectively sound is our perception of the vibrations of the air next to our ear-drum. People can perceive not all vibrations of the air but only when they occur at the rate of sixteen to twenty thousand times per second.Sounds may be periodical and non-periodical. If the vibrations of a physical body (vocal cords in our case) are rhythmical, the sound waves are periodical. The auditory impression of such periodical waves is a musical tone or a speech tone. If the wave is non-periodical, it is perceived as noise. Sound has a number of physical properties which all exist and manifest themselves simultaneously. They can be singled out from the others o nly for purposes of analysis. The first of these properties is frequency which is a number of vibrations per second.Our perception of the frequency is the pitch of the sound. The greater the frequency, the higher the pitch and vice versa. The frequency depends on certain physical properties of the vibrator, such as its mass, length and tension. The greater the mass of the vibrator, the slower its vibrations and the lower the pitch. The longer the vibrator, the slower the vibrations and the lower the frequency and the pitch. Here the difference between men and women and adults and children voices lies. Men's and adults' voices are lower than women's and children's are, because their vocal cords are thicker and longer.Tension depends on the elasticity of the vocal cords. The vocal cords of elderly people are not as elastic as the vocal cords of younger people, children especially, so their voices sound rather low. As the tension increases – the frequency increases and the pitch rises. The second physical property of sound is intensity, changes in which are perceived as variations in the loudness of sound. The intensity of sound is produced by the amplitude of vibrations (that is by the distance to which the air particles are displaced from their position of rest by the application of some external force).Intensity is measured in decibels. The intensity and frequency of sound are closely interdependent. The same amount of energy will produce either greater amplitude with a lower frequency or a higher frequency with smaller amplitude. Therefore if you increase the frequency without increasing the amount of energy you will shorten the amplitude and therefore reduce the intensity, that is produce a less loud sound. People are able to produce vowel sounds of various qualities or timbres. This is achieved through the action of the resonator mechanism.So the production and differentiation of vowels is based on the acoustic phenomenon that is called resonance. So unds coming from different resonators travel different lengths (distances) or have different carrying power. The distance is proportional to the volume of the resonator and the size of its orifice. Any sound has a certain duration or length. In other words it can exist and move only in time. The duration or length of a sound is the quantity of time during which the same vibratory motion, the same patterns of vibration are maintained. For this reason, the duration of a sound is often referred to as is quantity.The duration is measured in millisecond. We perceive the variations in duration as tempo or speed of utterance. In speech there are not definite boundaries between different speech sounds. So it’s very difficult to measure the length of separate sounds. In addition it should be mentioned that along with various articulatory classifications of speech sounds, there exist acoustic descriptions and classifications. The chief drawback of articulatory classifications is that t hey don’t describe and define all shades of typologically identical speech sounds, especially vowels.Besides, one and the same speech sound can be pronounced by different people with slightly different positions and movements of their speech organs. Acoustic classifications seem to overcome these difficulties as they are more detailed and accurate. The first acoustic classification was based on spectrographic analysis. It was worked out by Roman Jakobson, C. G. M. Fant and M. Halle. However, acoustic classification, though more precise, are not practically applied in teaching. The acoustic features of speech sounds can not be seen directly or felt.But there are some other fields of the application of acoustic phonetics: speech synthesis, health service, security systems, etc. IV. THE FUNCTIONAL ASPECT OF SPEECH SOUNDS 4. 1 Phoneme and Allophones Phoneticians not only describe and classify the material form of phonetic units. They are also interested in the way in which sound phenomena function in a particular language and what part they play in communication. The branch of phonetics that studies the linguistic function of consonant and vowel sounds, syllabic structures, word accent and prosodic features is called phonology.Unlike phonetics itself, whose domain is articulatory and acoustic features, phono

Back for Christmas Essay

InterpretationThe novel pricker for Christmas was compose by a highly skilled modern English generator John Collier (3 May 1901 6 April 1980). His stories may be broadly assort as fantasies, only when are really sui generis. They feature an acerbic wit and are usually ironic or low in t whizz. His distinction is a marvellous with a twist in the end. This beginning sewer stands a picture superb before the eyes of the reader. The title of the history under analysis is short but it excites many associations. On the one go the school text can be connected with a beautiful family holiday, but on the other hand the title sounds mysterious why BACK for Christmas in this flake anyhow the word Christmas itself already presupposes the musical theme of cold winter or something bad. The text under the analysis belongs to the psychological lawsuit as it is concerned mainly with the affable and emotional lives of the characters. It confines me think of the described puzzl e not once. The subject-matter of the story is a inhumane murder committed by a provincial go for-to doe with who ironicly fails to she-bop rid of his bossy married woman.The author tries to interpret the reader different approaches of men and women to the report of life. The story describes a difficult menstruation in the relations between maintain and wife. The problem, which is touched upon in the text, is the dominance of one of the spouses in the family. The author creates a head-plotted story which is true to life and a practical representation of spouses relations. Compositionally the text falls into the following parts exposition, narration, denouement, climax, ending. Exposition is revealed that Doctor work is invited to deliver a course of lectures in the US. At their valediction party Mrs.Carpenter promises the guests to impart her husband back for Christmas ignoring his slight interrogative about that. The author makes it quite unclouded that Hermione Car penter has always been exceedingly responsible for all arrangements in her husbands life and career as well as the trip. Narration describes the murder conservatively executed by the Doctor, who pretends to have rig a gold chain in the drain, which he uses as a decoy. after(prenominal) hitting his wife with a stretch pipe and making sure she is dead, he goes on to dispose of the body.Denouement takes line up forth when the first obstacle to the Doctors plan arises when he finds out that the irrigate has already been turned off byMrs. Carpenter, which causes him to go to the cellar. then there is a knock on the door, which scares him and brings about discouragement in the success of the affair. But receiving no response, the neighbours decide to come by later on and leave. Climax is when Mr. Carpenters endeavours to handle the body in the hole dig beforehand in the cellar, which his wife believed to be a preparation for a juvenile wine bin. The story ends with the Doctor arriving in America to find a garner waiting for him, which turns out to be a receipt for repairs of the wine bin and go out inevitably lead to the disco very of his wifes body. The idea of the text can be formulated like this to cross-file the dominance of one of the spouses and what it can lead. In my opinion this theme is actual, but a little exaggerated. The story is presented from the point of chance of a first-person observer.The author presents the characters fillly and indirectly. The main character is Doctor Carpenter. According to direct method of characterization we learn that he was a clever, but very unusual it jut outms to me he is very secretive, and as we elate further he is very cruel. The compressed character of the story is doctors wife Mrs. Carpenter. She plas dominating role in the family, she is very good housewife, carrying and coherent. She keeps always everything in perfect way. I feel about sympathy for her. The text Back for Christmas is writte n in a style of fiction. In the beginning of the text we can see the Carpenters living room that was filled with the closure friends who had come to say last- bit farewell the author apply this epithet to place us that their friends would be missing him very much. On the contrary with his wife doctor Carpenter wasnt sure he would come in time, he estimate something could spoil his plans. But his wife refulgent at them said he would be back in England for Christmas.The metaphor is used to reassure everybody to make them believe in this. So, the farewells began. Mrs. Carpenter tried her best to make all the arrangements on the high train and to prove it the author used such(prenominal) epithet as fluting of attentiveness and marvelous arrangements. Carpenters were going to drive to Southampton that eventide and would embark the following day. They have chosen this kind of transport for more prospering travelling without any double-deckertle and to stress it the author the used the repetition No trains, no bustle, no last minute worries. So doctor Carpenter has undertake for lecture only three months and for certain he would be a colossal success in America. His wife Hermione has full tagged along him to have some entertainments to see the big cities skyscrapers. Then the author uses repetitions No extensions. No fantastic post that show us that his hospital needs him. After the farewell dinner the maids washed up all the plates, come in to say goodbye and were in time to catch the afternoon bus to Devizes. The given story produced a large impression on me. It is full of ironical and sad moments.
