连词的用法英语文章ConjunctionsDefinitionSome words are satisfied spending an evening at home, alone, eating ice-cream right out of the box, watching Seinfeld re-runs on TV, or reading a good book. Others aren't happy unless they're out on the town, mixing it up with other words; they're joiners and they just can't help themselves. A conjunction is a joiner, a word that connects (conjoins) parts of a sentence. Coordinating ConjunctionsThe simple, little conjunctions are called coordinating conjunctions(you can click on the words to see specific descriptions of each one):(It may help you remember these conjunctions by recalling that they all have fewer than four letters. Also, remember the acronym FANBOYS: For-And-Nor-But-Or-Yet-So. Be careful of the words then and now; neither is a coordinating conjunction, so what we say about coordinating conjunctions' roles in a sentence and punctuation does not apply to those two words.)When a coordinating conjunctiontwo independent clauses, it is often (butalways) accompanied by a comma:•Ulysses wants to play for UConn, but he hasWhen the two independentconnected by a coordinating conjunctioncomma:•Ulysses has a great jump shot but hequick on his feet.The comma is always correct when usedseparate two independent clauses connected by a coordinating conjunction. See Punctuation Between Two Independent Clauses for further help.A comma is also correct when and is used to attach the last item of a serial list, although many writers (especially in newspapers) will omit that final comma:•Ulysses spent his summer studying basic math, writing, and reading comprehension.When a coordinating conjunction is used to connect all the elements in a series, a comma is not used:•Presbyterians and Methodists and Baptists are the prevalent Protestant congregations in Oklahoma.A comma is also used with but when expressing a contrast:•This is a useful rule, but difficult to remember.In most of their other roles as joiners (other than joining independent clauses, that is), coordinating conjunctions can join two sentence elements without the help of a comma.•Hemingway and Fitzgerald are among the Americanexpatriates of the between-the-wars era.•Hemingway was renowned for his clear style and his insights into American notions of male identity.•It is hard to say whether Hemingway or Fitzgerald is the more interesting cultural icon of his day.•Although Hemingway is sometimes disparaged for his unpleasant portrayal of women and for his glorification of machismo, we nonetheless find some sympathetic, even heroic, female figures in his novels and short stories.Beginning a Sentence with And or ButA frequently asked question about conjunctions is whetherand or but can be used at the beginning of a sentence.This is what R.W. Burchfield has to say about this use ofand:There is a persistentbelief that it isimproper to begin asentence with And,but this prohibitionhas been cheerfullyignored by standardauthors from Anglo-Saxon times onwards.An initial And is auseful aid to writersas the narrativecontinues.from The New Fowler's Modern English Usageedited by R.W. Burchfield. Clarendon Press: Oxford, England. 1996.Used with the permission of Oxford University Press.The same is true with the conjunction but. A sentencebeginning with and or but will tend to draw attention toitself and its transitional function. Writers shouldexamine such sentences with two questions in mind: (1)would the sentence and paragraph function just as wellAmong the coordinating conjunctions, the most common, of course, are and, but, and or. It might be helpful to explore the uses of these three little words. The examples below by no means exhaust the possible meanings of these conjunctions.ANDa.To suggest that one idea is chronologically sequential to another: "Tashonda sent in her applications and waited by the phone for a response."b.To suggest that one idea is the result of another: "Willie heard the weather report and promptly boarded up his house."c.To suggest that one idea is in contrast to another (frequently replaced by but in this usage): "Juanita is brilliant and Shalimar has a pleasant personality.d.To suggest an element of surprise (sometimes replaced by yet in this usage): "Hartford is a rich city and suffers from many symptoms of urban blight."e.To suggest that one clause is dependent upon another, conditionally (usually the first clause is an imperative): "Use your credit cards frequently and you'll soon find yourself deep in debt."f.T o suggest a kind of "comment" on the first clause: "Charlie became addicted to gambling — and that surprised no one who knew him."BUTa.To suggest a contrast that is unexpected in light of the first clause: "Joey lost a fortune in the stock market, but he still seemsable to live quite comfortably."b.To suggest in an affirmative sense what the first part of the sentence implied in a negative way (sometimes replaced by on the contrary): "The club never invested foolishly, but used the services of a sage investment counselor."c.To connect two ideas with the meaning of "with the exception of" (and then the second word takes over as subject): "Everybody but Goldenbreath is trying out for the team."ORa.To suggest that only one possibility can be realized, excluding one or the other: "You can study hard for this exam or you can fail."b.To suggest the inclusive combination of alternatives: "We can broil chicken on the grill tonight, or we can just eat leftovers.c.To suggest a refinement of the first clause: "Smith College is the premier all-women's college in the country, or so it seems to most Smith College alumnae."d.To suggest a restatement or "correction" of the first part of the sentence: "There are no rattlesnakes in this canyon, or so our guide tells us."e.To suggest a negative condition: "The New Hampshire state motto is the rather grim "Live free or die."f.T o suggest a negative alternative without the use of an imperative (see use of and above): "They must approve his political style or they wouldn't keep electing him mayor."Authority used for this section on the uses of and, but, and or: A University Grammar of English by Randolph Quirk and Sidney Greenbaum. Longman Group: Essex, England. 1993. Used with permission. Examples our own.The Others . . .The conjunction NOR is not extinct, but it is not used nearly as often as the other conjunctions, so it might feel a bit odd when nor does come up in conversation or writing. Its most common use is as the little brother in the correlative pair, neither-nor (see below):•He is neither sane nor brilliant.•That is neither what I said nor what I meant.>It can be used with other negative expressions:•That is not what I meant to say, nor should you interpret my statement as an admission of guilt.It is possible to use nor without a preceding negative element, but it is unusual and, to an extent, rather stuffy:•George's handshake is as good as any written contract, nor has he ever proven untrustworthy.The word YET functions sometimes as an adverb and has several meanings: in addition ("yet another cause of trouble" or "a simple yet noble woman"), even ("yet more expensive"), still ("he is yet a novice"), eventually ("they may yet win"), and so soon as now ("he's not here yet"). It also functions as a coordinating conjunction meaning something like "nevertheless" or "but." The word yet seems to carry an element of distinctiveness that but can seldom register.•John plays basketball well, yet his favorite sport is badminton.•The visitors complained loudly about the heat, yet they continued to play golf every day.In sentences such as the second one, above, the pronoun subject of the second clause ("they," in this case) is often left out. When that happens, the comma preceding the conjunction might also disappear: "The visitors complained loudly yetcontinued to play golf every day."Yet is sometimes combined with other conjunctions, but or and. It would not be unusual to see and yet in sentences like the ones above. This usage is acceptable.The word FOR is most often used as a preposition, of course, but it does serve, on rare occasions, as a coordinating conjunction. Some people regard the conjunction for as rather highfalutin and literary, and it does tend to add a bit of weightiness to the text. Beginning a sentence with the conjunction "for" is probably not a good idea, except when you're singing "For he's a jolly good fellow. "For" has serious sequential implications and in its use the order of thoughts is more important than it is, say, with because or since. Its function is to introduce the reason for the preceding clause:•John thought he had a good chance to get the job, for his father was on the company's board of trustees.•Most of the visitors were happy just sitting around in the shade, for it had been a long, dusty journey on the train.Be careful of the conjunction SO. Sometimes it can connect two independent clauses along with a comma, but sometimes it can't. For instance, in this sentence,•Soto is not the only Olympic athlete in his family, so are his brother, sister, and his Uncle Chet.where the word so means "as well" or "in addition," most careful writers would use a semicolon between the two independent clauses. In the following sentence, where so is acting like a minor-league "therefore," the conjunction and the comma are adequate to the task:•Soto has always been nervous in large gatherings, so it is no surprise that he avoids crowds of his adoring fans.Sometimes, at the beginning of a sentence, so will act as a kind of summing up device or transition, and when it does, it is often set off from the rest of the sentence with a comma:•So, the sheriff peremptorily removed the child from the custody of his parents.The Case of Then and ThanIn some parts of the United States, we are told, then andthan not only look alike, they sound alike. Like a teacherwith twins in her classroom, you need to be able todistinguish between these two words; otherwise, they'llbecome mischievous. They are often used and they shouldbe used for the right purposes.Than is used to make comparisons. In the sentence "Piggywould rather be rescued then stay on the island," we haveemployed the wrong word because a comparison is being madebetween Piggy's two choices; we need than instead. In the sentence, "Other than Pincher Martin, Golding did notwrite another popular novel," the adverbial construction"other than" helps us make an implied comparison; thisusage is perfectly acceptable in the United States butcareful writers in the UK try to avoid it (Burchfield). Generally, the only question about than arises when wehave to decide whether the word is being used as a conjunction or as a preposition. If it's a preposition(and Merriam-Webster's dictionary provides for thisusage), then the word that follows it should be in theobject form.•He's taller and somewhat more handsome than me.•Just because you look like him doesn't mean you canplay better than him.Most careful writers, however, will insist that than beused as a conjunction; it's as if part of the clauseintroduced by than has been left out:•He's taller and somewhat more handsome than I [amhandsome].•You can play better than he [can play].In formal, academic text, you should probably use than asa conjunction and follow it with the subject form of apronoun (where a pronoun is appropriate).Then is a conjunction, but it is not one of the little conjunctions listed at the top of this page. We can usethe FANBOYS conjunctions to connect two independentclauses; usually, they will be accompanied (preceded) bya comma. Too many students think that then works the sameway: "Caesar invaded Gaul, then he turned his attentionto England." You can tell the difference between then anda coordinating conjunction by trying to move the wordaround in the sentence. We can write "he then turned hisattention to England"; "he turned his attention, then, to England"; he turned his attention to England then." Theword can move around within the clause. Try that with a conjunction, and you will quickly see that the conjunctioncannot move around. "Caesar invaded Gaul, and then heturned his attention to England." The word and is stuckexactly there and cannot move like then, which is morelike an adverbial conjunction (or conjunctive adverb —see below) than a coordinating conjunction. Our originalsentence in this paragraph — "Caesar invaded Gaul, thenhe turned his attention to England" — is a comma splice,a faulty sentence construction in which a comma tries tohold together two independent clauses all by itself: thecomma needs a coordinating conjunction to help out, andthe word then simply doesn't work that way.Subordinating ConjunctionsA Subordinating Conjunction(sometimes called a dependent word or subordinator) comes at the beginning of a Subordinate (or Dependent) Clause and establishes the relationship between the dependent clause and the rest of the sentence. It also turns the clause into something that depends on the rest of the sentence for its meaning.•He took to the stage as though he had been preparing for this moment all his life.•Because he loved acting, he refused to give up his dream of being in the movies.•Unless we act now, all is lost.Notice that some of the subordinating conjunctions in the table below — after, before, since — are also prepositions, but as subordinators they are being used to introduce a clause and to subordinate the following clause to the independent element in the sentence.•It looks like as if it's going to snow this afternoon.•Johnson kept looking out the window like as though he had someone waiting for him.In formal, academic text, it's a good idea to reserve the use of like for situations in which similarities are being pointed out:•This community college is like a two-year liberal arts college.However, when you are listing things that have similarities, such as is probably more suitable:•The college has several highly regarded neighbors, like such as the Mark Twain House, St. FrancisHospital, the Connecticut Historical Society, andthe UConn Law School.•The problem is, that production in her department has dropped.•Remember, that we didn't have these problems before she started working here.As a general rule, if the sentence feels just as good without the that,if no ambiguity results from its omission, if the sentence is more efficient or elegant without it, then we can safely omit the that. Theodore Bernstein lists three conditions in which we should maintain the conjunction that:•When a time element intervenes between the verb and the clause: "The boss said yesterday that productionin this department was down fifty percent." (Noticethe position of "yesterday.")•When the verb of the clause is long delayed: "Our annual report revealed that some losses sustainedby this department in the third quarter of last yearwere worse than previously thought." (Notice thedistance between the subject "losses" and its verb,"were.")•When a second that can clear up who said or did what: "The CEO said that Isabel's department wasslacking off and that production droppedprecipitously in the fourth quarter." (Did the CEOsay that production dropped or was the drop a resultof what he said about Isabel's department? Thesecond that makes the sentence clear.)Authority for this section: Dos, Don'ts & Maybes of English Usage by Theodore Bernstein. Gramercy Books: New York. 1999. p. 217. Examples our own.clause.•Because e-mail now plays such a huge role in ourcommunications industry.When the "because clause" is properly subordinated toanother idea (regardless of the position of the clause inthe sentence), there is absolutely nothing wrong with it: •Because e-mail now plays such a huge role in ourcommunications industry, the postal service wouldvery much like to see it taxed in some manner. Correlative ConjunctionsSome conjunctions combine with other words to form what are called correlative conjunctions. They always travel in pairs, joining various sentence elements that should be treated as grammatically equal.•She led the team not only in statistics but also by virtue of her enthusiasm.•Polonius said, "Neither a borrower nor a lender be."•Whether you win this race or lose it doesn't matter as long as you do your best.Correlative conjunctions sometimes create problems in parallel form.

Here is a brief list of common correlative conjunctions.Conjunctive AdverbsThe conjunctive adverbs such as however, moreover, nevertheless, consequently, as a result are used to create complex relationships between ideas.

《现代语言学》问答题1.What are the main features of human language that have been specified by C.Hockett to show that it is essentially different from animal communication system?ArbitrarinessIt means that there is no logical connection between meanings and sounds. A good example is the fact that different sounds are used to refer to the same object in different languages.ProductivityLanguage is productive or creative in that it makes possible the construction and interpretation of new signals by its users. This is why they can produce and understand an infinitely large number of sentences.DualityLanguage is a system, which consists of two sets of structures. At the lower level there is a structure of sounds, which are meaningless by themselves. But the sounds of language can be grouped and regrouped into a large number of units of meaning, which are found at the higher level of the system. Then the units at the higher level can be arranged and rearranged into an infinite number of sentences. DisplacementLanguage can be used to refer to contexts removed from the immediate situations of the speaker. This property provides speakers with an opportunity to talk about a wide range of things, free from barriers caused by separation in time or place.Cultural transmissionLanguage is culturally transmitted. It is passed on from one generation to the next through teaching and learning rather than by instinct. In contrast, animal call systems are genetically transmitted.2. How are the English consonants classified?1)by manner of articulation.a.stops(plosive爆破音): [p],[b],[t],[d],[k],[g]b.fricatives(磨擦音): [f],[v],[s],[z],[ θ],[ð], [∫], [ʒ], [h]c.affricates(破擦音): [ t∫], [dʒ]d.liquids(lateral边音,流音): [l], [r]e.nasals(鼻音): [m],[ n],[ŋ]f.glides (semivowels半元音): [w], [ j]2)by place of articulation :a.bilabial(双唇音): [p],[b],[m],[w]biodental(唇齿音): [f],[v]c.dental(舌齿音): [θ],[ ð]d.alveolar(齿龈音): [t],[d],[s],[z],[n],[l],[r]e.palatal(腭音): [∫], [ʒ],[ t∫], [dʒ], [j]f.velar(软腭音): [k], [g], [ŋ ]g.glottal(喉音,声门单): [h]3. What criteria are used to classify the English vowels? 英语的元音是如何分类的?1) According to the position of the tongue, vowels may be distinguished as front vowels such as [i:] [i] [e] [æ] [a], central vowels such as [ɜ:] [ə] [ʌ], and back vowels such as [u:] [ʊ] [ɔ:] [ɔ] [ɑ:]2) According to the openness of the mouth, we classify the vowels into four groups: close vowels such as [i:] [i] [u:] [ʊ], semi-close vowels such as [e] [ɜ:], semi-open vowels such as [ə] [ɔ:], and open vowels such as [æ] [a] [ʌ] [ɔ] and [ɑ:].3) According to the shape of the lips, vowels are divided into rounded vowels and unrounded vowels. In English all the front and central vowels are unrounded vowels, all the back vowels, with exception of [ɑ:], are rounded.4) According to the length of the vowels, the English vowels can also be classified into long vowels and short vowels. The long vowels include [i:] [ɜ:] [ɔ: ] [u:] [ɑ:],while the rest are short vowels.4. What are phonemic contrast, complementary distribution, and minimal pair?If two phonetically similar sounds can occur in the same environments and they distinguish meaning, they are in phonemic contrast. [p], [b]If two phonetically similar sounds are two allophones of the same phoneme and they occur in different environments, they are said to be in complementary distribution. [p], [ph].When two different forms are identical in every way except for one sound segment which occurs in the same place in the strings, the two words are said to form a minimal pair. For example, kill and bill.5. Explain with examples the sequential rule, the assimilation rule, and the deletion rule.Sequential rule refers to the rule that governs the combination of sounds in a particular language.For example, if a word begins with a [l] or a [r] , then the next sound must be a vowel. If three consonants should cluster together at the beginning of a word, the combination should obey the following three rules:the first phoneme must be /s/the second phoneme must be /p/ or /t/ or /k/the third phoneme must be /l/ or /r/ or /w/Assimilation rule assimilates one sound to another by “copying” a feature of a sequential phoneme, thus making the two phones similar.For example, the [i:] sound in words like bean, green, team, and scream. This is because in all these sound combinations the [i:] sound is followed by a nasal [n] or [m].Deletion rule tells us when a sound is to be deleted although it is orthographically represented.For example, in the pronunciation of the word sign or design, there is no [g] soundalthough it is represented in spelling by the letter g. But in their corresponding forms signature, designation, the [g] represented by the letter g is pronounced. The rule: delete a [g] when it occurs before a final nasal consonant.6. What are suprasegmental features? How do the major suprasegmental features of English function in conveying meaning?Suprasegmental features are phonological features above the sound segment level. The major suprasegmental features in English are word stress, sentence stress and intonation.1)The location of stress in English distinguishes meaning, such as `import and im`port. The similar alternation of stress also occurs between a compound noun and a phrase consisting of the same elements. A phonological feature of the English compounds is that the stress of the word always falls on the first element and the second element receives secondary stress, for example: `blackbird is a particular kind of bird, which is not necessarily black, but a black `bird is a bird that is black.2) Sentence stress refers to the relative force which is given to the words in a sentence. The more important words such as nouns, main verbs, adjectives, adverbs, and demonstrative pronouns, are pronounced with greater force and made more prominent. And the other categories of words (articles, personal pronouns, auxiliary verbs, prepositions, and conjunctions) are usually not stressed. But to give special emphasis to a certain notion, a word in sentence that is usually unstressed can be stressed to achieve different effect. Take the sentence “He is driving my car.” For example, to emphasize the fact that the car he is driving is not his, or yours, but mine, the speaker can stress the possessive pronoun my, which under normal circumstances is not stressed.3)English has four basic types of intonation: When spoken in different tones, the same sequence of words may have different meanings. Generally speaking, the falling tone indicates that what is said is a straight-forward, matter-of-fact statement, the rising tone often makes a question of what is said, and the fall-rise tone often indicates that there is an implied message in what is said.7. Discuss the types of morphemes with examples.Free morphemes: They are the independent units of meaning and can be used freely all by themselves, for example, “book-” in the word “bookish”.Bound morphemes: They are those that cannot be used independently but have to be combined with other morphemes, either free or bound, to form a word such as “-ish” in “bookish”.Bound morphemes can be subdivided into roots and affixes. A root is seen as part of a word; it can never stand by itself although it has a clear and definite meaning, such as “gene-” in the word “generate”. Affixes are of two types: inflectional and derivational. Inflectional morphemes manifest various grammatical relations or grammatical categories such as “-s” in the word “books” to indicate plurality of nouns. Derivational affixes are added to an existing form to create a word such as “mis-” in the word “misinform”. Derivational affixes can also be divided into prefixes andsuffixes. Prefixes occur at the beginn ing of a word such as “dis- ” in the word “dislike”, while suffixes occur at the end of a word such as “-less” in the word “friendless”.8. What is the relation between sense and reference?Sense and reference are two terms in the study of meaning. (1) Sense is concerned with the inherent meaning of the linguistic form. It is the collection of all the features of the linguistic form; it is abstract and de-contextualized. It is the aspect of meaning that dictionary compilers are interested in. Reference means what a linguistic form refers to in the real, physical world; it deals with the relationship between the linguistic element and the non-linguistic world of experience. (2) Obviously, linguistic forms having the same sense may have different references in different situations. On the other hand, there are less frequent occasions when linguistic forms with the same reference might differ in sense, e.g. “morning star” and “evening star”.9. What are the major lexical sense relations?1)Synonymya)Dialectal synonyms --- regional dialectse.g. British English: autumn/liftAmerican English: fall/elevatorb)Stylistic synonymse.g. old man, daddy, dad, father, male parentc)Synonyms that differ in their emotive or evaluative meaninge.g. collaborator & accompliced)collocational synonymse.g. accuse…of/ charge…with/ rebuke…fore)semantically different synonymse.g. amaze: confusion and bewildermentastound: difficulty in believing2)Polysemye.g. “table” has many meanings such as 1.a piece of furniture 2. a level area, a plateau and etc.3)HomonymyHomophones: identical in sound e.g. night/ knightHomographs: identical in spelling e.g. bow v./ bow n.4)Hyponymye.g. superordinate: furniturehyponyms: bed, table5)Antonymya)Gradable antonymse.g. old and young are immediately recognized as antomyms, between whichthere exist intermediate forms such as “mature”, “middle-aged”b)complementary antonymse.g. a person can be either alive or dead; there is no third possibilityc)Relational oppositese.g. husband and wife are a paior of relational opposites.10. Illustrate Searle’s classification of speech acts with examples.According to Searle, speech acts fall in five general categories. Specific acts that fall into each type share the same illocutionary point, but differ in their strength.1)Representatives/assertives: stating or describing, saying what the speaker believes to be trueTypical cases: stating, believing, swearinge.g. (I swear)I have never seen the man before.(I state)The earth is a globe.2)Directives: trying to get the hearer to do somethingTypical cases: Inviting, suggesting, requesting, advising, warning, threatening, orderinge.g. Open the window, please.You’d better go to the clinic.3)Commissives: committing the speaker himself to some future course of action Typical cases: Promising, undertaking, vowinge.g. I promise to come.4)Expressives: expressing feelings of attitude towards an existing stateTypical cases: apologizing, thanking, congratulatinge.g. I’m sorry for the mess I have made.It’s really kind of you to have thought of me.5)Declarations: bringing about immediate changes by saying somethingThe successful performance of an act of this type brings about the correspondence between what is said and reality.e.g. I now declare the meeting open.I fire you!11. Illustrate Grice's Cooperative Principle with examples.Grice's Cooperative Principle consists of four maxims: QUANTITY, QUALITY, RELATION, and MANNER.1)A: What are you reading?B: A book.A knowsB is reading a book, and is asking about the content of the book. Simply by saying "a book", B is not offering enough information. The implicature here is: I do not want to talk to you right now. In this case, the maxim of QUANTITY is violated.2)He is made of iron.Our common sense tells us no human being is made of iron. Obviously this is a false statement and has violated the maxim of QUALITY. The implicature here is: he is as strong as iron.3)A: Mrs. Smith was such a bore at the party last night.B: It's really chilly here. I want to go out to warm up.When A is talking about Mrs. Smith, B turns to talk about something totally irrelevant.Therefore the maxim of RELATION is violated. The implicature here is: It is impolite to say that.4)a. Miss Smith sang "Home sweet home".b. Miss Smith produced a series of sounds that corresponded closely with the song of "Home sweet home".The two sentences actually are basically talking about the same thing. But sentence b is stated in such a way that makes it more obscure for the audience and therefore violates the maxim of MANNER. The implicature here is: Miss Smith does not sing well and I do not like her singing.12. With examples, give some plausible explanations for linguistic change.The rapid development of science and technologye.g. fax, laser printer, hi-tech, CD-ROM, lapto p computer and etc.Social and political changes and political needse.g. mini-summit, jungle war, Euro and etc.more and more women have taken up activities formerly reserved for mene.g. chairman---chairpersonfireman---fire fighterpoliceman---police officerThe way children acquire a languagee.g. “It’s I.”---“It’s me”.Economy of memory(results in grammar simplification)e.g. By analogy to foe/foes, dog/dogs, speaker started saying cows as the plural of cow instead of kine.Theory of least efforte.g. Cheap is always used in the place of cheaplySimplification of grammar occurs, so does elaboration and complication.13. Is standard language better than non-standard language? Explain your answer.The standard language is a superposed, socially prestigious dialect of language. It is the language employed by the government and the judiciary system, used by the mass media, and taught in educational institutions, including school settings where the language is taught as a foreign or second language. Nonstandard, or vernacular, languages are language varieties other than the standard language. Standard language is not superior to nonstandard language at all. The designation of the standard language variety is motivated by historical and socio-political reasons and has nothing to do with any supposed linguistic superiority intrinsic to the grammatical components of that particular language variety. In view of language as an effective means of communication, no single dialect of a language, be it standard or nonstandard, is any more correct, any more logical, or any purer than any other dialect of the language. All dialects of a language are equally effective in expressing ideas.14. What is the relationship between pidgin and creole?A pidgin is a variety of language that is generally used by native speakers of otherlanguages as a medium of communication. A pidgin is used for some practical purposes, such as trading, by groups of people who do not know each other' s languages. It is not a native language of a particular region, but only a marginal language used by people whose cultures are sharply separated and whose business contact is very specialized .As a simplified language, a pidgin involves reductions in sounds, vocabulary and syntax. Although pidgins are simplified languages, they are rule-governed.A Creole language is originally a pidgin that has become established as a native language in some speech community. When a pidgin comes to be adopted by a population as its primary language, and children learn it as their first language, then the pidgin language is called a creole. A creole involves expansion in sounds, vocabulary and syntax. Creoles are fully developed languages.。

Most problems in psycholinguistics are more concrete, involving the study of language acquisition especially in children and linguistic performance such as producing and comprehending utterances or sentences among adults.4、名词解释:DualityBy Duality is meant the property of having two levels of structures, such that units of the primary level are composed of elements of the secondary level and each of the two levels has its own principles of organization. The property of duality only exists in such a system, namely, with both elements and units.Besides, the language is hierarchical.5、名词解释:DisplacementDisplacement means that human languages enable their users to symbolize objects, events and concepts which are not present (in time and space) at the moment of communication. Displacement benefits human beings by giving them the power to handle generalizations and abstractions. In a word, the intellectual benefits of displacement to us is that it makes it possible for us to talk and think in abstract terms.6、Do you think that onomatopoeia indicates a non-arbitrary relationship between form and meaning? Why or why not?No matter whether you say “Yes” or “No”, you cannot deny that onomatopoeia needsarbitrariness. Before we feel a word is onomatopoeic we should first know which sound the word imitates. In order to imitate the noise of flying mosquitoes, there are many choices like “murmurous” and “murderous”. They both bear more or less resemblance to the genuine natural sound, but “murmurous” is fortunately chosen to mean the noise while “murderous” is chose n to mean something quite different. They are arbitrary as signifiers.(参考答案)No, I don't think so. There exists the arbitrary relationship between the sound of a morpheme and its meaning. Also, in English, totally different words are used to describe the sound. In fact, arbitrariness and onomatopoeic effect may work at the same time. For example, Widdowson cites a line from Keats' Ode to a Nightingale to illustrate. The murmurous haunt of flies on summer eves. To test this, just think of using the similar sounding word murderous to substitute murmurous, and no connectionwhatsover will be established between the sounds and the little noises of the flying flies. "It's only when you know the meaning that you infer that the form is appropriate." (我的答案)7、Illustrate the origins of language you have known.The sing-song theory: it holds that language develops from primitive ritual songs of praise.The Ding-Dong theory: the natural response theory postulates that language began with vocal expressions being assigned to objects found in the environment.The pooh-pooh theory: the theory traces language back to interjections which expresses the speakers’ emotions.The yo-he-ho theory: it explains that language originated form the cries uttered during strain of work.The bow-wow theory: it holds that language originated from people’s imitations of animal cries and other sounds heard in nature.Ta-Ta theory: it believes that body movement preceded language. language began as an unconscious vocal imitation of these movements.8、Language is generally defined as a system of arbitrary vocal symbols used for human communication. Explain it in detail.Language is a means of verbal communication. It is instrumental in that communicating by speaking or writing is a purposeful act. It is social and conventional in that language is a social semiotic and communication can only take place effectively if all the users share a broad understanding of human interaction including such associated factors as nonverbal cues, motivation, and socio-cultural roles.Chapter 2 Phonetics5phonetics选择题1、Pair ___________ doesn’t form a minimal pair.A cat and actB tip and dipC gap and capD pat and pad2、The study of the production of speech sounds is closely connected with ____________.A articulatory phoneticsB auditory phoneticsC acoustic phoneticsD arbitrary phonetics3、The study of the physical properties of speech sounds is closely connected with ____________.A acoustic phoneticsB articulatory phoneticsC auditory phoneticsD arbitrary phonetics4、The study of the perception of speech sounds is closely connected with .A acoustic phoneticsB articulatory phoneticsC auditory phoneticsD arbitrary phonetics5、Pair ________is not in complementary distribution.A spot and potB stop and topC light and gladD school and cool判断题1、A single phoneme always represents a single morpheme.2、When the vocal folds are apart, the air can pass through easily and the sound produced is said to be voiced.3、Cave and shave forms a minimal pair.4、Phonetics studies how speech sounds are produced, transmitted, and perceived.5、The tongue is divided into five parts: the tip, the blade, the front, the back and the root.主观题1、Please describe what is phoneme.The speech sound segments that can distinguish or contrast words in sound and meaning are phonemes. (A phoneme is the minimal or smallest distinctive linguistic unit in a language.)2、Please describe what is complementary distribution.The different allophones of the same phoneme never occur in the same phonetic context. When two or more allophones of one phoneme never occur in the same linguistic environment they are said to be in complementary distribution.答案:AAACC ××√√√6English Consonan t选择题1、The classification and description of English consonants are based on ___________________.A narrow and broad transcriptionB the shape of vocal tractC the place and manner of articulationD the position of the tongue2、According to the manner of articulation, [m] is a ___________.A nasalB plosiveC bilabialD lateral3、In terms of the place of articulation, the following sounds [t], [n], [z] share the feature of ____________.A alveolarB velarC palatalD bilabial4、Which of the following sounds is a bilabial?A [ t ]B [ b ]C [ g ]D [ d ]5、Which of the following sounds is an alveolar?A [ d ]B [ m ]C [ g ]D [ b ]判断题1、The difference between vowels and consonants lies in the obstruction of the airstream.2、According to the manner of articulation, [s] is a fricative.3、English consonants can be classified in terms of place of articulation and the part of the tongue that is raised the highest.4、According to the manner of articulation, some of the types into which the consonants can be classified are stops, fricatives, bilabial and alveolar.5、/d/ is a voiced alveolar stop.主观题Please describe what are consonants.Consonants are sounds produced by constricting or obstructing the vocal tract at some place to divert, impede or completely shut off the flow of the air in the oral cavity.答案:CAABA √√××√7English Vowels1、The classification and description of English vowels are based on ___________________.A the position of the tongueB the shape of the lipsC the shape of vocal tractD all of the above2、The difference between vowels and consonants lies in ___________________.A the intonation of the soundsB the obstruction of the airstreamC the place and manner of articulationD the aspiration of the sounds3、A ____ vowel is one that is produced with the front part of the tongue maintaining the highest position.A centralB frontC middleD back3、can be differentiated by a number of factors: the position of tongue in the mouth, the openness of the mouth, the shape of the lips, and the length of the vowels.A Consonant soundsB Voicing soundsC Vowel soundsD devoicing sounds主观题1、Please describe what are vowels.V owels are sounds produced without obstruction, so no turbulence or a total stopping of the a ir can be perceived.2、What are the criteria that a linguist uses in classifying vowels?1. V owels may be distinguished as front, central and back in terms of the position of the tongue in the mouth.2. According to how wide our mouth is opened, we classify the vowels into four groups: close vowels, semiclose vowels, semi-open vowels, and open vowels.3. According to the shape of the lips, vowels are divided into rounded vowels and unrounded vowels.4. The English vowels can also be classified into long vowels and short vowels according to the length of the sound.答案:DBBCChapter 3 Phonology8phonology选择题1、Of all the speech organs, the _______ is/are the most flexible.A lipsB tongueC mouthD vocal cords2、A(n) ___________ is a unit that is of distinctive value. It is an abstract unit, a collection of distinctive phonetic features.A soundB phoneC phonemeD allophone3、The different phones which can represent a phoneme in different phonetic environments are called the ____ of that phoneme.A phonesB soundsC allophonesD phonemes4、Since /p/ and /b/ are phonetically similar, occur in the same environments and they can distinguish meaning, they are said to be ___________.A in phonemic contrastB the allophonesC in complementary distributionD minimal pair5、The assimilation rule assimilates one sound to another by “copying”a feature of a sequential phoneme, thus making the two phones ____________.A sameB identicalC exactly alikeD similar判断题1、Phonetics is different from phonology in that the latter studies the combinations of the sounds to convey meaning in communication.2、Phonology is concerned with how the sounds can be classified into different categories.3、The rules governing the phonological patterning arelanguage specific.4、Distinctive features of sound segments can be found running over a sequence of two or more phonemic segments.5、When two different forms are identical in every way except for one sound segment which occurs in the same place in the strings, the two words are said to form a phonemic contrast.主观题What are the major differences between phonology and phonetics?1.They differ in their approach and focus.2.Phonetics is of a general nature; it is interested in all the speech sounds used in all human languages: how they are produced, how they differ from each other, what phonetic features they p ossess, how they can be classified.3.Phonology, on the other hand, is interested in the system of sounds of a particular languag e; it aims to discover how speech sounds in a language form patterns and how these sounds are use d to convey meaning in linguistic communication.答案:BCCA D √×√√×9coarticulation选择题1、When such simultaneous or overlapping articulation are involved, we call the process .A coarticulationB aspirationC nasalizationD epenthesis2、In producing a nasal the soft palate is lowered to allow airflow through the .A nasal tractB vocal foldsC vocal cordsD larynx3、The fact that the vowel in lamb has some quality of the following nasal is a phenomenon we call .A devoicingB velarizationC nasalizationD aspiration4、In coarticulation, if the sound becomes more like the following sound, as in lamb, it is known as .A perseverative coarticulationB aspirationC nasalizationD anticipatory coarticulation5、When we use a simple set of symbols in our transcription, it is called a .A aspirationB narrow transcriptionC nasalizationD broad transcription判断题1、In English, the distinction between aspirated [p?] and unaspirated [p] is not phonemic.2、In the word peak, /p/ is unaspirated, phonetically transcribed as [p]3、Aspiration is a distinctive feature in English.4、In phonetic terms, phonemic transcriptions represent the “narrow” transcription.5、Speech is a continuous process, so the vocal organs donot move from one sound segment to thenext in a series of separate steps.主观题名词解释:CoarticulationCoarticulation:Simultaneous or overlapping articulations, as when the nasal quality of a nasal sound affects the preceding or following sound so that the latter becomes nasalized. If the affected sound becomes more like the following sound, it is known as anticipatory coarticulation; if the sound shows the influence of the preceding sound, it is perseverative coarticulation.答案:AACDD √×××√10suprasegmentals选择题1、Which of the following is NOT a Suprasegmental feature?A toneB intonationC syllableD stress2、In a syllable, a vowel often serves as ____________.A onsetB sequenceC peak or nucleusD coda3、The word “digitalization” consists of _______ syllables, and _________ morphemes.A six/ threeB five/ threeC six/ fourD five /five4、The word “digitalization” consists of _______ syllables, and _________ morphemes.A six/ threeB six/ fourC five /fiveD five/ three5、Distinctive features can be found running over a sequence of two or more phonemic segments. The phonemic features that occur above the level of the segments are called _______.A immediate constituentsB phonetic componentsC suprasegmental featuresD semantic features主观题1、名词解释:suprasegmental featuresThe features that occur above the level of the segments and can distinguish meaning are called suprasegmental features, which include syllable structure, stress, tone and intonation.2、名词解释: intonationWhen pitch, stress and sound length are tied to the sentence rather than the word in isolation,they are collectively known as intonation.3、Illustrate with examples how suprasegmental features can affect meaning.1. The location of stress in English distinguishes meaning, such as `import and im`port. The similar alternation of stress also occurs between a compound noun and a phrase consisting of the same elements. A phonological feature of the English compounds, is that the stress of the word always falls on the firstelement and the second element receives secondary stress, for example: `blackbird is a particular kind of bird, which is not necessarily black, but a black `bird is a bird that is black.2. The more important words such as nouns, verbs adjectives, adverbs, etc. are pronounced with greater force and made more prominent. But to give special emphasis to a certain notion, a word in sentence that is usually unstressed can be stressed to achieve different effect. Take the sentence “He is driving my car.” for example. To emphasize the fact that the car he is driving is not his, or yours, but mine, the speaker can stress the possessive pronoun my, which under normal circumstances is not stressed.3. English has four basic types of intonation, known as the four tones: When spoken in different tones, the same sequence of words may have different meanings. Generally speaking, the falling tone indicates that what is said is a straight-forward, matter-of-fact statement, the rising tone often makes a question of what is said, and the fall-rise tone often indicates that there is an implied message in what is said.答案:CCCBCChapter 4 Morphology11morphology选择题1.Derivational affixes are bound morphemes added to existing form to construct new words. English derivational affixes are divided into ________and _______.A prefixes, infixesB suffixes and infixesC prefixes, suffixesD morphemes, allomorphs2.In the word “unavailability”, ______________ is the root.A unB availableC availD ability3.In today’s grammar we normally say that English does not have a “future tense”. This is because in English ________________.A the future can be expressed in many waysB the future is not expressed by morphological changeC the future is expressed by modal verbsD the future belongs to the category of “aspect”4.The morpheme “vision” in the word “television” is a(n)____________.A inflectional morphemeB bound formC free morphemeD bound morpheme5.Which of the following words is made up of bound morphemes only?A televisioB happinessC ecologyD teacher6.Morpheme is the minimal unit of meanin7.–ing is an “inflectional suffix”8.Stems in English can be classified into derivational morphemes and inflectional morphemes.9.The bound morpheme in “apples” is inflectional morpheme.10.Although is an open-class word.主观题11..名词解释:RootRoot: Root refers to the base form of a word that cannot be further analyzed without loss of identity. That is to say, it is that part of the word that is left when all the affixes are removed. And roots can be further classified into free root morpheme and bound root morpheme.12.名词解释:AllomorphAllomorph: A morpheme, like a phoneme, is a linguistic abstraction, which must be realized as certain phonetic forms or variants in different phonetic environments. Each of the phonetic for ms or variants is a morph. A single morpheme may be phonetically realized as two or more morph s. The different morphs that represent or which are derived from one morpheme is called the allom orphs of that morpheme答案:CCBCC √√×√×12word formation选择题1._________can best describe the following group of words: table--tables, influenza--flu.A Inflection and derivationB Derivation and blendingC Inflection and abbreviationD Compound and derivation2.Which of the following ways of word-formation does not change the grammatical class of the stem?A inflectionB compoundC derivationD coinage3._________can best describe the word formation rules of thefollowing group of words: to burgle (from burglar), Eurodollar (from European + dollar).A Back-formation and blendingB Inflection and derivationC Derivation and blendingD Compound and derivation4._________can best describe the following group of words: table—tables, day + break—daybreak.A Inflection and derivationB Derivation and blending.C Compound and derivation.D Inflection and compound5.__________can be best describe the following group of words: advertisement—ad, bicycle—bike.A abbreviationB compoundC derivationD coinage6.“Invention” is a form of compounding, in which two words are blended by joining the initial par t of the first word and the final part of the second word, or by joining the initial parts of the two w ords.7.Blending is a relatively complex form of compounding.8.Derivation does not change the grammatical class of the stem.9.Derivation can be further divided into two sub-types: the derivational type and the compositional type.10.Inflection shows a relationship between roots and affixes.主观题11.What is the distinction between inflectional affixes andderivational affixes?1.When an affix, usually a suffix in English, indicates the tense of a verb, the plurality of a counta ble noun, or the comparative/superlative degree of an adjective, it is termed as inflectional morphe me. For example, '-ed' in 'worked', '-ing' in 'studying', '-s' in 'books' or 'er' in 'shorter' and 'est' in 'lo ngest' are all inflectional morphemes. Usually, the inflectional morpheme will not change the part of speech of a word to which it is attached.2.But a derivational morpheme usually changes the part of speech of a word to which it is attached . When we attach '-al' to the word 'nation' to form 'national', the part of speech of the word 'nation', i.e. a noun, has been changed into an adjective. As we can see, the concept of derivational morphe me is related to a kind of word formation called derivation.答案:CAADA ×√×√×Chapter 5 Syntax13concept of grammar选择题1.A sentence is considered ____ when it does not conform to the grammatical knowledge in the mi nd of native speakers.A wrongB ungrammaticalC rightD grammatical2.

The syntactic rules of any language are ____ in number.A smallB largeC finiteD infinite判断题6.Descriptive grammar refers to grammarian’s attempt to legislate what speakers’ grammatical rules should be, rather than what they are.7.Grammatical sentences are formed following a set of syntactic rules.8.Universally found in the grammars of all human languages, syntactic rules that comprise the system of internalized linguistic knowledge of a language speaker are known as linguistic competence9.The syntactic rules of any language are finite in number, but there is no limit to the number of sentences native speakers of that language are able to produce and comprehend.10.In a complex sentence, the two clauses hold unequal status, one subordinating the other.答案:DBDDD XX√√√主观题1. What are the basic components of a sentence?Normally, a sentence consists of at least a subject and its predicate which contains a finite verb or a verb phrase.2. What are the major types of sentences? Illustrate them with examples.①Traditionally, there are three major types of sentences. They are simple sentence, coordinate (compound) sentence, and complex sentence. A simple sentence consists of a single clause which contains a subject and a predicate and stands alone as its own sentence.For example: John reads extensively.②A coordinate sentence conta ins two clauses joined by a linking word that is calledcoordinat ing conjunction, such as “and”, “but”, “or”.For example: John is reading a linguistic book, and Mary is preparing for her history exam.A complex sentence contains two, or more, clauses, one of which is incorporated into the other. The two clauses in a complex sentence do not have equal status, one is subordinate to the other.For example: Before John gave her a lecture, Mary showed no interest in linguistics.14Cultural Approach选择题1.

As the first step of their scientific investigation of language,linguists have to observe and collect linguistic facts before they can do anything else.2. Phonological rules that govern the combination of sounds in a particular language are called sequential rules.3. An independent unit of meaning that can be used freely by itself is called a free morpheme.4. The study of the linguistic meaning of words, phrases, and sentences is called semantics.5. In making conversation, the general principle that all participants are expected to observe is called the Cooperative principle proposed by J. Grice.6. If a linguistic study describes and analyzes the language people actually use, it is said to be descriptive.7. Morpheme is the smallest meaningful unit of language.8. Referent is what a linguistic form refers to in the real world; it is a matter of the relationship between form and the reality.9. Although the development of a communicative system is not unique to human beings, the natural acquisition of language as a system of highly abstract rules and regulations for creative communication is what distinguishes humans from all other animal species.10. Language exists in time and changes through time. The description ofa language at some point of time is called a synchronic study of language.11. An essential difference between consonants and vowels is whether the air coming up from the lungs meets with any obstruction when a sound is produced.12. The morphemes that cannot be used by themselves, but must be combined with other morphemes to form words arecalled bound morpheme.13. XP may contain more than just X. For example, the NP "the boy who likes his puppy" consists of Det, N and S, with Det being the specifier, N the head and S the complement.14. Hyponymy is the relationship which obtains between specific and general lexical items. The word that is more general in meaning is called superordinate.15. V owels can be nasalized. The vowel nasalization rule is an assimilation rule, which, for the most part, is caused by articulatory or physiological process in which successive sounds are made identical, or more similar, to one another.16.Clear [1]and dark[1]are allophones of the same one phoneme /1/.They never take the same position in sound combinations, thus they are said to be in complementary distribution.17. A root is often seen as part of a word, but it can never stand by itself although it bears clear, definite meaning.18. A complex sentence contains two or more clauses, one of which is incorporated in the other.19. While the meaning of a sentence is abstract and decontextualized, that of an utterance is concrete and context-dependent.Ⅲ. Directions: Judge whether each of the following statements is true or false. Put a T for true or F for false in the brackets in front of each statement. If you think a statement is false, you must explain why youthink so and give the correct version. (2%×10=20%)(T ) 1.Radar is an example of acronym.(T ) 2.What is a permissible sequence in one language may not be so in another language.( F) 3.English has only three bilabials,which are [p][b][m]. ([W]) (T) 4.Phonetically similar sounds might be related in two possible ways: phonemic contrast and complementary distribution.(F ) 5.In the history of any language the writing system always came into being before the spoken form. (The opposite is right.) ( T) 6.Bloomfield's theory of syntax has two central ideas: one is the notion of discovering procedures and the other is that of constituent structure.( F ) 7.A compound is the combination of only two words. (It can combine more than two words, e.g. stay-at-home ) (T ) 8.Transformational rules are also called rewrite rules.( T) 9. The writing system of a language is always a later invention used to record speech; thus there are still many languages in today?s world that can only be spoken, but not written.(F ) 10.The task of the semantic component is to convert deep structures into surface structures. (transformational component)(T ) 11.Sense relations are in fact a part of the semantic structures of English.( F) 12. In such sound combinations as /bi:p/, /geip/ and /su:p/, the voiceless stop /p/, occurring in the final position, is unaspirated, i.e. pronounced with the strong puff of air withheld to some extent. (aspirated)(F )13. Linguists suggest that language is very variable phenomenon, and that this variability is not governed by any rules. That is one of the reasons why we say language is arbitrary. (The fact that different languages have different words for the same object is a good proof that human language is arbitrary.)(F ) 14.Chomsky thinks that human beings are innately endowed with the capacity to form some concepts rather than others. (…form universal concepts.)(F) 15. The part of speech of the compound is always determined by the part of speech of the second element, without exception. (…not necessarily…. e.g. …Eight-year-old? is an adjective.)(T ) 16. The relationship between the embedded clause and its matrix clause is one of a part to the whole.(T ) 17. The contextualist view of meaning holds that meaning should be studied in terms of the situational context and linguistic context.(T ) 18. Searle?s classification of illocutionary acts is based on the classification of performative verbs.(T )19. A general difference between phonetics and phonology is thatphonetics is focused on the production of speech sounds while phonology is more concerned with how speech sounds distinguish meaning.(F ) 20. Only words of the same parts of speech can be combined to form compounds. (Not necessarily. e.g. open-minded, stay-at-home, etc.)(T ) 21. Sentences are not formed by randomly combining lexical items, but by following a set of syntactic rules that arrange linguistic elements in a particular order.( F) 22. According to Searle's classification of illocutionary acts, inviting, ordering, advising, promising and apologizing all fall into the category of directives. (Promising falls into the category of commissives.)Ⅳ.Directions: Explain the following terms, using one or twoexamples for illustration. (3%×10=30%)1. cultural transmission (as a defining feature of human language)One of the major defining features of human language. Humans are born with the ability to acquire a language, but different from animals, the actual use of human language is not genetically transmitted, rather it is culturally transmitted, i.e. it has to be taught and learnt. (P11)2. phonic medium of languageThe limited range of sounds that are used in human language communication, i.e.the speech sounds. (P13)3. inflectional morphemesInflectional morphemes are morphemes that are used to indicate thegrammatical relations and categories, such as number, tense, degree and case. E.g.-ed,-(e)s,-est in English. workers, children; walking, walked; biggest ; John?s. (P37)4. suprasegmental featuresSuprasegmental features refers to the phonemic features that occur above the level of the segments (phoneme), they are phonological properties of such linguistic units as syllable, word and sentence. The main suprasegmental features include stress, intonation, and tone. (P28)5. locutionary actLocutionary act refers to the act of uttering words, phrases, and clauses.It is the act of conveying literal meaning by means of syntax, lexicon and phonology. For example, by saying "You have left the door wide open",the locutionary act performed by the speaker is that he has uttered all the words and expressed what the words literally mean.6. bound morphemesThe morphemes that cannot be used by themselves, but must be combined with other morphemes to form words are called bound morpheme. For example, -s in dogs, -al in national, and dis- n disclose, cannot occur alone. (P35)7.duality of structureLinguists refer duality (of structure) to the fact that in all languages so far investigated, one finds two levels of structure or patterning. At the first,higher level, language is analyzed in terms of combinations of meaningful units (such as morphemes, words etc.); at the second, lower level, it is seen as a sequence of segments which lack any meaning in themselves, but which combine to form units of meaning. According to Hu Zhanglin et al. (p.6), language is a system of two sets of structures, one of sounds and the other of meaning. This is important for the workings of language. A small number of semantic units (words), and these units of meaning can be arranged and rearranged into an infinite number of sentences (note that we have dictionaries of words, but no dictionary of sentences!). Duality makes it possible for a person to talk about anything within his knowledge. No animal communication system enjoys this duality, or even approaches this honor. (P11)8. hyponymyHyponymy is the relationship which obtains between specific and general lexical items.The word that is more general in meaning is called superordinate.9. surface structureThere are two levels of syntactic structure, deep structure and surface structure. Surface structure correspond to the finalsyntactic form of the sentence which results from appropriate transformations. (P57)10. assimilation ruleThe …assimilation rule? assimilates one segment to another by …copying? afeature of a sequential phoneme, thus making the two phones more similar.(This rule accounts for the raring pronunciation of the nasal[n] that occurs within a word. The rule is that within a word the nasal consonant[n] assumes the same place of articulation as the following consonant. The negative prefix “in-“ serves as a good example. It may be pronounced as [in], or [im] when occurring in different phonetic contexts: e. g., indiscrete-[ ](alveolar) inconceivable-[ ](velar) input-[…imput](bilabial)) (P27) The …deletion rule?tells us when a sound is to be deleted although is orthographically represented. While the letter …g?is mute in …sign?, …design?and …paradigm?, it is pronounced in their corresponding derivatives: …signature?, …designation?and …paradigmatic?. The rule then can be stated as: delete a [g] when it occurs before a final nasal consonant. This accounts for some of the seeming irregularities of the English spelling. (P28)11. rootA root is often seen as part of a word; it can never stand by itself although it bears clear, definite meaning; it must be combined with another root or an affix to form a word. A “root” is the base form of a word that cannot be further analyzed witho ut total loss of identity. In other words, a “root”is that part of the word left when all the affixes are removed. “Internationalism” is a four-morpheme derivative which keepsits free morpheme “nation” as its root when “ inter-”, “-al” and “-ism” are tak en away. (P35)12. narrow transcriptionIn handbook of phonetics, Henry Sweet made a distinction between “narrow” and “broad” transcriptions, which he called “Narrow Romic”. The former was meant to symbolize all the possible speech sounds, including even the most minute shades of pronunciation while Broad Romic or transcription was intended to indicate only those sounds capable of distinguishing one word from another in a given language.13. stemA “stem” is any morpheme or combination of morphemes to which an affix can be added. It may be the same as, and in other cases, different from, a root. For example, in the word “friends”, “friend” is both the root and the stem, but in the word “friendships”, “friendships” is its stem, “friend” is its root. Some words (i. e., compounds ) have more than one root ,e.g., “mailman” , “girlfriend” ,e tc. (P35)14. derivational affixesA kind of bound morphemes, added to existing forms to create new words. There are three kinds according to position in the new words: prefix, suffix and infix. (P35)15. predication…Predication analysis? is a new approach for sentential meaning analysis. …Predication? is usually considered an important common category shared by propositions, questions, commands, etc. Predication is to break down the sentence into their smaller constituents: argument (logical participant) and predicate (relation element). The …predicate?is the major or pivotal element governing the argument. We may nowdistinguish a …two-place predicate?(which governs two argu ments, e.g., subject and object), a …one-place predicate?(which governs one argument, i.e., subject) and a …no-place predicate?that has simply no argument(no real subject or object).Ⅴ. Answer the following questions.(10%×2=20%)1. Why do we say tree diagrams are more advantageous and informative than linear structure in analyzing the constituent relationship among linguistic elements? Support your statement with examples.2. One of the main features of our human language is arbitrariness. Can you briefly explain what is this feature refers to? Give examples if necessary. (10 points)By “arbitrariness”, we mean there is no logical connection between meanings and sounds (see I .1). A dog might be a pig if only the first person or group of persons had used it for a pig. Language is therefore largely arbitrary. But language is not absolutely seem to be somesound-meaning association, if we think of echo words, like “bang”, “crash”, “roar”, which are motivated in a certain sense. Secondly, some compounds (words compounded to be one word) are not entirely arbitrary either. “Type” and“write” are opaque or unmotivated words, while “type-writer” is less so, or more transparent or motivated than the words that make it. So we can say “arbitrariness” is a matter of degre e.3. The phonological features that occur above the level of individual sounds are called suprasegmental features. Discuss the main suprasegmental features, illustrating with examples how they function in the distinction of meaning.…Suprasegmental phonology?refers to the study ofphonological properties of linguistic units larger than the segment called phoneme, such as syllable, word and sentence.Hu Zhuanglin et al.,(p,73) includes stress, length and pitch as what they suppose to b e “principal suprasegmental features”, calling the concurrent patterning of three “intonation”. Dai Weidong(pp23-25) lists three also, but they are stress, tone and intonation.4. Explain with examples the three notions of phone, phoneme and allophone, and also how they are related.5. What is the speech act theory advanced by John Austin? Please give examples for illustration.Speech act theory was proposed by J. L. Austin and has been developed by J. R. Searle. Basically, they believe that language is not only used to inform or to describe things, it isoften used to “do things”, to perform ac ts. Austin suggests three basic senses in which in saying something one is doing something and three kinds of acts are performed simultaneously: locutionary act言内行为:------the act of uttering words, phrases, clauses. I t’s an act of conveying literal meaning by means of syntax,lexicon,and /doc/c93918915.html,ly.,the act of saying something :the utterance of a sentence with determinate sense and reference.言内行为指的是用句子来叙述,报告,描写。

ZEMAX Users' Knowledge Base - /kbHow to Tilt and Decenter a Sequential Optical Component/kb/articles/24/1/How-to-Tilt-and-Decenter-a-Sequential-Optical-ComponentBy Mark NicholsonPublished on 07/26/2005This article explains:z What coordinate break surfaces are, and how they workz How to use the Global Vertex report to check your workz Why coordinate break surfaces usually come in pairsz Why coordinate break surfaces have to be co-locatedz How to do all this the easy, simple, fun wayThe article is accompanied by a ZIP archive containing the sample ZEMAX files used. This can be downloaded from the final page of the article.The Coordinate Break SurfaceIn the sequential ray-tracing mode of ZEMAX, the order in which surfaces are entered matters enormously. The order specified in the Lens Data Editor (LDE) gives the exact order in which light interacts with the component surfaces of the optical system.One surface is therefore placed a thickness (a distance along the local z-axis) away from the previous surface. This is known as a local coordinate system, because the location of a surface is specified in terms of the previous surface.A Coordinate Break (CB) surface allows you to specify the location of the next surface as being shifted in x and y, and tilted (rotated) in x, y and z as well as simply shifted in z. The Coordinate Break is a dummy surface: that is, it has no refractive or reflective power and cannot bend rays. Its sole purpose is to define a new coordinate system in terms of the current one. Using such a surface allows you to separate the geometric location of a surface from its optical properties.In this article we will show how to tilt and decenter an optical component while leaving the position of all other components unchanged. After explaining precisely how to do this, we will show a tool that simplifies the whole process, but it is important you understand how the tool works, and so a careful reading of the whole article is advised. In the attached zip file, you will find a file, starting point.zip, which shows three glass windows, the central one of which is two optical materials glued together.Eack of the windows has rectangular apertures applied (double-click on any surface and look at the Aperture tab to verify). Any ray that lands outside the aperture on a surface will be terminated.In the above screenshot, positive z is in the left-to-right direction, positive y is going up the page and positive x is going into the page. This is a right-handed coordinate system, in which z is on your index finger, y on your thumb and x on your middle finger, and your index finger is pointing from left to right, as shown by the coordinate axes in the bottom left-hand corner or the 3D Layout.Our task in this article is to tilt and center the central window while leaving the other two windows in exactly their original locations. How will we know when we have achieved this? ZEMAX has a report which is vital whenever you are working on a tilted or decentered system.Open Reports > Prescription Report, and look at the section headed Global Vertex:The Global Vertex report lists the position and orientation of the vertex of each surface with respect to the Global Coordinate Reference Surface (GCRS). In this design, surface 1 is the GCRS, but any surface may be selected either from the Type tab of the Surface Properties or from the Misc tab of the System Properties dialog boxes.From the Global Vertex report it can be seen that all surfaces are on-axis with respect to the GCRS, as the rotation matrix is a unit matrix for all surfaces and the {x,y} coordinates of each surface is zero. Surface 7 (the front surface of window 3) has {x, y, z} coordinates {0,0,33} with respect to surface 1, the GCRS.The Coordinate Break (CB) surface allows you to specify a decentration in x, decentration in y, tilt in {x, y, z} as well as shift in z (thickness) that affects all subsequent surfaces. It also has an order flag, the purpose of which we will discuss later.Our first task is to decenter the middle window, without disturbing the location of any other surfaces. Decentering a ComponentIn order to decenter the middle window, click anywhere on surface 4 (it has the comment Front Window2) and press the INSERT key on the keyboard. A new surface will be inserted, and all surfaces from the oldsurface 4 onwards will have been renumbered (so that surface 5 now has the comment Front Window2).Now double-click on the new surface 4 and set it to a Coordinate Break surface:Then scroll along to the y-decenter and enter a value of -5 mm. The Layout Plot and Prescription Report show the consequence. All surfaces from the Coodinate Break onwards are decentered by -5 mm.The effects of a CB last until another CB is encountered, therefore two coordinate breaks are usually required: one to implement the tilt/decenter and the other to restore the original axis.To demonstrate this, click on Surface 8 (the front of window 3), press INSERT again and make the new surface a CB. Make the thickness of this surface 10 mm, and make the thickness of surface 7 zero, so that the second CB is colocated with the back of the middle window. Give this CB a decenter in y of +5. You should now have the following (open intermediate step.zmx from the zip if you got lost). {Note that because of the rectangular apertures on the surfaces, rays that miss the middle window are terminated. This is an essential part of the sequential model. If you wish to model a system in which rays that miss themiddle window carry on to hit the third window, you must use non-sequential ray-tracing.}The restoring CB restores the original coordinate axes so that subsequent surfaces are back in their original positions.Setting the values of the restoring coordinate break surface by hand is not good practice, as its easy to forget that the second CB needs to be adjusted whenever the first one is. However, ZEMAX makes it easy to automate: just double-click on the y-decenter of the second CB and choose a Pick-Up solve to lock the value to the first CB, as follows:Do this with the decentration in x, and for the tilt parameters also, but leave the order flag = 0 for both CBs at this time. (This is an error, but we will see why in the next page).You should be able to set any value of decenter in x and y, and ZEMAX will restore the original coordinate system at the second CB. If you got lost, open intermediate step2.zmx from the attached zip archive. We will now move onto tilts.Tilting a componentReset all parameters on the first CB to zero. The parameters of the second CB should automatically set themselves to zero because of the pick-up solves. Then set the tilt-x of the first CB to 20 degrees. At first glance, this looks like all we need to do, but when the Global Vertex report is looked at carefully, it is obvious that something is wrong.A y-decentration of 0.68 mm has been introduced by the x-tilt. This is because the second coordinate break is implemented some distance along z of the new, x-tilted coordinate system. In order that weintroduce a pure tilt with no decentration, there must be zero z-shift between the two CB surfaces. This is achieved by a dummy propagation before the second CB.Insert a dummy surface immediately after the second coordinate break. The second CB currently has a thickness of 10. Set this to 0, and make the thickness of the new dummy surface 10. Now the z-shift between the two CBs is a total of 2 mm, so make the thickness of the surface immediately before the second CB -2, and make the thickness of the second CB +2. This dummy propagation places the two CBs at the same point in space, and so the untilting operation introduces no decentration.The dummy surface has no optical effect because we trace -2 mm in air followed by +2 mm in air, so no rays are bent, no optical path length is added. The dummy surface may be hidden using the "Do Not Draw This Surface" and "Skip Rays From this Surface" controls on the Draw tab of the Surface Properties.However, the way in which the dummy propagation thickness has been set is unsatisfactory. What would happen if the thickness of one of the glass surfaces changed, either by hand or during optimization? The second CB would no longer be correctly placed. The key thing is that the second CB must be at the same position as the first, and ZEMAX has a simple, powerful way to ensure that this condition is always met: a position solve.A position solve sets the surface after it to have a specified distance from another surface. Double-click on the thickness of the surface immediately before the second CB (this currently has a thickness of -2), and in the solve dialog box choose:Note that the position solve lets us go back through any number of surfaces until we get to the first coordinate break Then put a pick-up solve on the thickness of the second CB, that picks up the value of the position solve and multiplies it by -1. Now change the thickness of the glass surfaces between the two CB surfaces. No matter what thickness you enter, the second CB is always exactly co-located with the first, and so can undo it perfectly.Finally, notice one more thing. Set a y-tilt of 30 degrees and an x-tilt of 10 degrees. Note that the second CB no longer undoes the first one perfectly. This is because the order of the tilts matters. If we tilt about x, and then tilt about y in this new tilted position, then we must untilt about y and then untilt about x in order to restore the original coordinate system. This is what the Order flag is for.If the Order flag is zero, the CB surface executes such that decenters are done first, and then tilts in order. If the Order flag is non-zero, the CB executes in reverse order. This meas that a single CB can unstrip any compound tilt/decenter introduced by another other CB that it is co-located with.The final system is included as final system.zmx in the attached ZIP archive. Here is the system, with any number of tilts and decenters, showing that the position of the third window is unaffected . Note the dummy surface has been hidden.But isn't there any easier way to do all this? There is!The Tilt/Decenter Elements ToolThis is the easy way to tilt/decenter an optical element. Re-open starting point.zmx, and then click on Tool > Miscellaneous > Tilt/Decenter Elements, and enter whatever tilt/decentration data you want, for example:Note that this tool does everything we did by hand! Using the tool is highly recommended as the standard technique by which you should tilt or decenter optical components in your system.Summary and ReferencesIn summary, in order to tilt/decenter an optical element in a sequential optical system:z Two coordinate break surfaces are usually required, one to perform the compound tilt/decenter and the other to restore the original axisz The two CB surfaces must be co-located, which is done most easily with a position solvez The decenters and tilts of the second CB must be the exact reverse of the first CB. This is most easily achieved with pick-up solvesz The order in which decenters and tilts are applied by the second CB must be the reverse of that used by the first. The Order flag is used to achieve thisz The Tilt/Decenter Element Tool is the easiest way to achieve all this in one step, and is strongly recommended.z Check the results with the Global Vertex section of the Prescription Report to ensure surfaces are placed where you expect them to be.ReferencesThere are no external references for this article.。
