If a linguistic study aims to describe and analyze the language people actually use, it is said to be descriptive (modern). If the linguistic study aims to lay down rules for correct and standard behavior in using language, i.e. to tell people what they should say and what they should not say, it is said to be prescriptive.2. Synchronic static state grammer; diachronic dynamic historical developmentngue (language): the abstract linguistic system shared by all the members of a speech community, stable.; Parole (speaking): the realization of langue in actual use, concrete, specific, changeable. What a linguist ought to do, according to Saussure, is to abstract langue from instances of parole.sociological or sociolinguistic point of view4. American linguist N. Chomsky Competence: the ideal user’s knowledge of the rules of his language,stable,prerequisite; Performance: the actual use of language in concrete situations,changeable.psychologically or psycholinguistically.5.Traditional grammar ---- prescriptive, written, Latin-based frameworkModern linguistics ----- descriptive, spoken, not necessarily Latin-based framework nguage is a system of arbitrary vocal symbols used for human communication. Design Features of Language.1:Arbitrariness2:duality:The structural organization of language into two abstract levels: meaningful units (e. g. words in written language) and meaningless segments (e. g. sounds, letters in spoken language).1. Combine meaningless sounds into meaningful linguistic unitsbine small units into big units3.productivity/creativity:Language is resourceful because of its duality and its recursiveness. We can use it to create new meanings.4.Displacement: which are not present (in time and space) at the moment of communication.5.cultural transmission7.Six Functions of language:Addresser---Emotive the addresser expressed his attitude to the topic or situation of communication; Addressee---Conative使动xx aims to influence the addressee’s course of action or ways of thinking；Context---referentia所指, xx conveys a message or informationl;Message---Poetic xx uses language for the sole purpose of displaying the beauty of language itself;Contact--Phatic communication寒暄, xx tries to establish or maintain good interpersonalrelationships with the addressee；Code--Metalingual xx uses language to make clear the meaning of language itself.8.M. A. K. Halliday.Metafunctions of Language:Ideational function:About the natural world in the broadest sense, including our own consciousness; Relates to the context of culture. Interpersonal function:About the social world, especially the relationship between speaker and hearer ; Relates to the context of situation. Contextual function:About the verbal world, especially the flow of information in a text; Relates to the verbal context.9.A phone is a phonetic unit or segment. The speech sounds we hear and produce during linguistic communication are all phones. But a phone doesn’t necessarily distinguish meaning; some do, some don’t. A phoneme is a phonological unit;It is aunit that is of distinctive value;It is an abstract unit;It is not any particular sound, but rather it is represented or realized by a certain phone in a certain phonetic context.10. phones are placed within square brackets: [ ], and phonemes in slashes: / /.11./p/ in [pi:k] (peak) : an aspirated [ph]12./p/ in [spi:k] (speak): an unaspirated [p]13.Both [ph] and [p] are called as allophones of /p/14. The different phones which can represent a phoneme in different phonetic environments are called allophones. [p, ph] are two different phones and are variants of the phoneme /p/. Such variants of a phoneme are called allophones of the same phoneme.15. Minimal pairs: Pairs of words which differ from each other only by one sound; More precisely: two words which are identical in every way except for one sound segment that occurs in the same place in the string.16.Sequential rules The patterning of sounds in a particular language is governed by rules;The phonological system determines which phonemes can begin a word, end a word, and follow each other.Refer to the rules that govern the combination of sounds in a particular language.17.Assimilation rule—assimilates one sound to another by “copying”a feature of a sequential phoneme, thus making the two phones similar, e.g. the prefix in-18. When pitch, stress, and sound length are tried to the sentence rather than the word in isolation, they are collectively known as intonation: the falling tone, the rising tone, the fall-rise tone, the rise-fall tone.19.单元音monophthongs 双元音diphthongs20.Morpheme: the minimal unit of meaning. It is the smallest unit that carries grammatical and /or semantic meaning.Morphs:The smallest meaningful phonetic segments of an utterance on the level of parole.The phonological or orthographic forms which realize morphemes. Allomorphs:A member of a set of morphs which represent the same morpheme. Allomorphs are phonological or orthographic variants of the same morpheme.21.Free morpheme is one that may constitute a word (free form) by itself, such as bed, tree, sing, dance, etc.Bound morpheme is one that may appear with at least one other morpheme, such as “-s”in “dogs”, “-al”in “national”, “dis-”in “disclose”, “-ed”in “recorded”, etc.22.Derivational morphemes—the morphemes which change the category, or grammatical class,or meaning of words. e.g. modern —modernizeInflectional morphemes:purely grammatical markers;signifying tense, number, and case;not changing the syntactic category; never adding any lexical meaningpounding (合成词) blackboard; Derivation(派生词) --ful ---able;Back-formation逆构词法television televise; Borrowing—loan words (外来词); Clipping（缩略词）labtory lab; Blending（混成法）motel; Acronym（词首字母）APEC；Coinage/Invention (Neologism) 创新词nylon24.Open: n. V. Adj. Adv. Bound morphemes :roots and affixes25.①traditional categories: n., v., adj., adv., prep., conj., aux., pronoun….②non-traditional categories: determiner (Det限定词), degree words (Deg程度词), qualifier (Qual修饰语).26.Three criteria are used to determine a word’s category: meaning, inflection, distribution.27.the structure or elements of phrases:XP rule specifier+head+complement28.NP (Det) + N + (PP)…29.VP (Qual) + V + (NP)…30.AP (Deg) + A + (PP)…31.PP (Deg) + P + (NP)…32.S →NP VP33.Deep structure: formed by the XP rule in accordance with the head’s subcategorization properties, is called ds. Surface structure: corresponding to the final syntactic form of the sentence which results from appropriate transformations, is called ss. Do insertion, WH movement.34.Syntactic movement is dictated by rules traditionally called transformation. A special type of rule that can move an element from one position to another.35.Head: A V N P36. Semantics is generally considered to be the study of meaning in language.37. The conceptualist view holds that there is no direct link between a linguistic form And what it refers to (i.e.between language and real world ); rather, in the interpretation of meaning, they are linked through the mediation of concepts in the mind. Semantic triangle by ogden and richards: symblo/form, thought/ reference/, refrent.38.Contextualism: Meaning should be studied in terms of situation, use, context ---- elements closely linked with language behavior. JR forth39.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 dictionary compilers are interested in. Reference----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. The relationship between sense and reference:And, if等只有sense, 而无reference.一个sense可以有许多reference同一referenece可有不同的sense，Mrs Thatcher, & the Iron Lady. Morning Star & Evening Star.40.Major sense relations: Synonymy (同义关系)Antonymy (反义关系)Polysemy (多义关系)Homonymy (同音/形异义) Hyponymy (上下义关系)41.Antonymy: Complementary antonyms (互补反义词)非A即B; Gradable antonyms (程度反义词) :AB有中间, very .. How..; Relational opposites （关系对立词）丈夫妻子42.Sense relations between sentences: Synonymy (同义关系) inconsistency (自相矛盾)Entailment (蕴涵)Presupposition (预设)X is a contradiction (自相矛盾)X is semantically anomalous (反常的43.man [+HUMAN +ADULT +MALE] women [+HUMAN +ADULT －MALE]girl [+HUMAN －ADULT －MALE] child [+HUMAN －ADULT OMALE]father: PARENT (x, y) & MALE (x)x is a parent of y, and x is male.take: CAUSE (x, (HA VE (x, y)))x causes x to have y.give: CAUSE (x, (~HA VE (x, y)))x causes x not to have y.44.predication analysis: G.leech: argument 名词predicate 动词45. Pragmatics --- the study of the intended meaning of a speaker (taking context into consideration). Pragmaticists regard meaning as something that is realized in the course of communication.Semantics --- the study of the literal meaning of a sentence (without taking context into consideration).Semanticists take meaning to be an inherent property of language. Essential difference is that whether in the study of meaning the context of use is considered. 不senmantics.46.Sentence meaning: It is abstract and context-independent; it’s the literal meaning of a sentence. Utterance meaning: It is concrete and context-dependent; It’s the intended meaning of a speaker.It is the product of sentence meaning and context. Therefore, it is richer than the meaning of the sentence.47.John Austin’s speech act theory.Performatives (行事话语): I promise Constatives (述事话语)48.A locutionary act (言内行为) is the act of saying words, phrases, clause; it is an act of conveying literal meaning by means of syntax, lexicon and phonology.An illocutionary act (言外行为) is the act of expressing the speaker’s intention; it is the act performed in saying something. 关注A perlocutionary act (言后行为) is the act performed by or resulting from saying something; it is the consequence of, or the change brought about by the utterance.act performed by saying sth.49.Searle’s classification of speech acts:Representatives (陈述) Directives (指令)Commissives (承诺) Expressives (表达) Declarations (宣布)50.CP Grice:The maxim of quality: ck adequate evidence.The maxim of quantity信息充足; The maxim of relation继续下去; The maxim of manner方式表达清楚模糊词绕口1. P_________ is the study of how speakers of a language use sentences to effect successful communication.Pragmatics2. The notion of c_________ is essential to the pragmatic study of language.context3. The meaning of a sentence is a_______, and decontexualized.abstract4. P________ were sentences that did not state a fact or describe a state, and were not verifiable.Performatives1. An i__________ act is the act of expressing the speaker’s intention; it is the actperformed in saying something.illocutionary2. A c_________ is commit the speaker himself to some future course of action.commissive3. An e________ is to express feelings or attitude towards an existing state.expressive4. There are four maxims under the cooperative principle: the maxim of q_______, the maxim of quality, the maxim of relation and the maxim of manner.quantity4. ____C______ is the act performed by or resulting from saying something; it is the consequence of, or the change brought about by the utterance.A. A locutionary actB. An illocutionary actC. A perlocutionary actD. A performative act5.

Pragmatics treats the meaning of language as something intrinsic and inherent. F2. What essentially distinguishes semantics and pragmatics is whether in the study of meaning the context of use is considered. T3. The major difference between a sentence and an utterance is that a sentence is not uttered while an utterance is. F4. Speech act theory was originated with the British philosopher John Searle. F5. Speech act theory started in the late 50’s of the 20th century. T6. Austin made the distinction between a constative and a performative. T7. Perlocutionary act is the act of expressing the speaker’s intention. F1. A __bound_____ morpheme is one that cannot constitute a word by itself.2. On, before and together are__close_____words—they are words which do not take inflectional endings.3. Bound morphemes are classified into two types: __affix__ and __root__ root.4. Pronouns, prepositions,conjunctions and articles are all_close__class items.5. handsome consists of 2 morphemes, one is the _free___ morpheme hand, the other is the __bound__ morpheme some.1.There are _C__ morphemes in the word denationalization?A. 3B. 4.C. 5.D. 62.

Syntactic movement is dictated by rules traditionally called __transformation______.5. The head is the word __n v a p___.1. Syntax is a subfield of linguistics that studies the sentence structure of language, including the combination of morphemes into words.F2. In English syntactic analysis, four phrasal categories are commonly recognized and discussed, namely, noun phrase, verb phrase, infinitive phrase, and auxiliary phrase. F3. A noun phrase must contain a noun, but other elements are optional.T1. Phonetics studies the phonic medium of a certain language. ( F )2. The long vowels are all tense vowels and the short vowels are all lax vowels. ( T )3. In English, pill and bill are a minimal pair, and so are pill and till, pin and ping. ( T )4. The phoneme /p/ and /b/ can occur in the same environments and they distinguish meaning, therefore they’re in phonetic complementary distribution. ( F )5.

英语专业英语语言学期末复习总结

英语语言学一、名词解释第一课1.Synchronic共时性: S aid of an approach that studies language at a theoretical “point” intime.\ A kind of description which takes a fixed instant (usually, but not necessarily, the present), as its point of observation. Most grammars are of this kind.ngue语言: The abstract linguistic system shared by all members of a speech community.nguage: Language is a system of arbitrary vocal symbol used for human communication.4.Arbitrariness任意性:One design feature of human language, which refers to the face that theforms of linguistic signs bear no natural relationship to their meaning.第二课1.Phoneme音位: Phonology is concerned with the speech sounds which distinguish meaning. Thebasic unit in phonology is called phoneme; it is a unit that is of distinctive value.2.Allophone音位变体: The different phones which can represent a phoneme in different phonetic environment are called the allophones of that phoneme.3.Minimal pair最小对立体: When two different forms are identical in every way except for onesound segment which occurs in the same place in the stings, the two words are said to form aminimal pair.第三课1.Morphology形态学: Morphology is a branch of grammar which studies the internal structure of words and the rules by which words are formed.2.Derivational morphemes派生词素:Some morphemes which change the category or grammatical classof words are called…3.Inflectional morphemes曲折词素: Some bound morphemes which are for the most part purely grammatical markers and signify such concepts as tense, number, case and so on.第四课1.Syntax语法句法: A branch of linguistics that studies how words are combined to form sentencesand the rules that govern the formation of sentences.2.Syntactic categories句法范畴: Words can be grouped together into a relatively small numberof classes, called syntactic categories.3.Deep structure 深层结构: Formed by the XP rule in accordance with the head’s subcategorization properties, is called deep structure or D- structure.4.Surface structure 表层结构: Corresponding to the final syntactic form of the sentence whichresults from appropriate transformations, is called Surface structure or S- structure.第五课1.Reference指称: 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.Homonymy同音异义: Homonymy refers to the phenomenon that words having different meanings havethe same form, i.e. different words are identical in sound or spelling, or in both.3.Hyponymy 上下义关系: Hyponymy refers to the sense relation between a more general, more inclusive word and a more specific word.第六课1.Pragmatics语用学: Pragmatics can be defined as the study of how speakers of a language use sentences to effect successful communication.2.Utterance话语: a sentence as what people actually utter in the course of communication.3.Utterance meaning话语意义: Utterance is based on sentence meaning; it is realization of the abstract meaning of a sentence in a real situation of communication, or simply in a context.4.Illocutionary act言外行为: An illocutionary act is the act expressing the speaker’s intention; it is the act performed in saying something.二、简答题第一课1．What are the major branches of linguistics? What does each of them study?Phonetics: The study of sounds used in linguistic communication. It describes individual speech sounds and indicates their physical or phonetic properties.Phonology:It studies the ways in which these sounds form patterns and systems and how they work to convey meaning in the system of language.Morphology:A field of linguistics focused on the study of the forms and formation of words in a languageSyntax: A set of rules that govern how words are combined to form phrases and sentences.Pragmatics: the study of the use of language in a social context.2．What characteristics of language do you think should be included in a good, comprehensive definition of language?The important characteristics which should be included in a good definition of language are separately: systematic, arbitrary and vocal.First of all, language is a system. It has its own set of rules for people to abide by, or people will use the language in a wrong way.Second, language is arbitrary in the sense that there is no intrinsic connection between a linguistic symbol and what the symbol stands for.The fact that different languages have different words for the same object is a good illustration of the arbitrary nature of language. Third, language is vocal because the primary medium for all languages is sound.3．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?1) Arbitrariness: no natural/motivated/logical relationship between the sign and what thesign stands for.2)Productivity:provides opportunities for sending messages that have never been sent beforeand for understanding novel messages.3) Duality: language is a system, which consists of two sets of stuctures, or two levels.4) Displacement: can be used to refer to things real or imagined, past, present or future5) Cultural transmission第二课1. How do phonetics and phonology differ in their focus of study? Who do you think will be moreinterested in the different between say[i]and[i],[p] and[ph],a phonetician or a philologist? Why? 语音学和音位学的研究中心有何不同?语音学家和音位学家哪一个更关心清晰音的区别?为什么?Phonetics — description of all speech sounds and their find differences.Phonology — description of sound systems of particular languages and how sounds function to distinguish meaning.A phonetician would be more interested in such differences cos such differences will not cos differences inmeaning.2. What is phone? How is it different from a phoneme? how are allophones related to a phoneme?Phone is a phonetic unit, it has no meaning.Phoneme is a phonological unit with distinctive value .The phoneme /l/ can be realized as dark/l-/and clear/l/,which are allophones of the phoneme /l/Allophones---actual realization of a phoneme in different phonetic contexts.第三课1. Think of three morpheme suffixes, give their meaning and specify the types of stem they may be suffixed to. Give at least two examples of each.Suffix: -ingMeaning: denoting a verbal action, an instance of this, or its resultStem type: added to verbsExamples: fighting: denote the action of battlebuilding: denote the action of constructionSuffix: -ableMeaning: able to beStem type: added to verbsExamples: avoidable: able to be prevented fromcalculable: able to be measured or assessedSuffix: -istMeaning: denoting a member of a profession or business activityStem type: added to nounsExamples: dramatist: a person who writes playsdentist: a person who treats the teeth disease2. Think of three morpheme prefixes, give their meaning, and specify the types of stem they may be prefixed to. Give at least two examples of each.1)prefix: un-meaning: denoting the absence of a quality or state; notstem type: added to nounsexamples: unacademic: not adopting or characteristic of a scholarly approach orlanguageunhappy: not happy2)prefix: anti-meaning: opposed to; againststem type: added to nounsexamples: anti-abortion: opposing or legislating against medically inducedabortionanti-art: against the traditional art3)prefix: re-meaning:once more; afresh; anewstem type: added to verbsexamples: restart: start once morereaccustom: accustom (someone) to something again第五课1. What are the major types of synonyms in English?并举例1)dialectal synonyms-----synonyms used in different regional2)Stylistic synonyms: synonyms differing in style3)Synonyms that differ in their emotive or evaluative meaning4)Collocational synonyms: what words they go together with5)Semantically different synonyms: differ from the words themselves2. Explain with examples “homonymy”, “polysemy”, and “hyponymy”.Homonymy: Homonymy refers to the phenomenon that words having different meanings have the same form, i.e., different words are identical in sound or spelling, or in both. When two words are identical in sound, they are homophones. When two words are identical in spelling, they are homographs. When tow words are identical in both sound and spelling, they are complete homonyms. The examples are as followed:Homophones: rain/reign night/knight piece/peaceHomographs: bow v./bow n. tear v./tear n.Complete homonyms: fast adj./fast v.Polysemy: while different words may have the same or similar meaning, the same one word may have more than one meaning. This is what we call polysemy, and such a word is calleda polysemic word. The more commonly used a word is, the more likely it has acquired morethan one meaning. For example, the word table has at least six meanings when we look it up in the dictionary:1. a piece of furniture2.all the people seated at a table3.the food that is put on a table4. a thin flat piece of stone, mental, wood, etc5.orderly arrangement of facts, figures, etc6.part of a machine-tool on which the work is put to be operated onHyponymy refers to the sense relation between a more general, more inclusive word and a more specific word. The word which is more general in meaning is called the superordinate, and the more specific words are called its hyponyms. Hyponyms of the same superordinate are co-hyponyms to each other. For example,Superordiante: flowerHyponyms: rose, tulip, carnation, lily, morning golory第六课1. What does pragmatics study? How does it differ from traditional semantics?答： Generally speaking, pragmatics is the study of meaning in the context. It studies meaning in a dynamic way and as a process. In order to have a successful communication, the speaker and hearer must take the context into their consideration so as to effect the right meaning and intention. The development and establishment pragmatics in 1960s and 1970s resulted mainly from the expansion of the study semantics. However, it is different from the traditional semantics. The major difference between them lies in that pragmatics studies meaning in a dynamic way, while semantics studies meaning in a static way. Pragmatics takes context into consideration while semantics does not. Pragmatics takes care of the aspect of meaning that is not accounted for by semantics.2. What are the five types of illocutionary speech acts Searle has specified? What is the illocutionary point of each type?答：(1) representatives: stating or describing, saying what the speaker believes to be true(2) directives: trying to get the hearer to do something(3) commissives: committing the speaker himself to some future course of action(4) expressives: expressing feelings or attitude towards an existing(5) declarations: bringing about immediate changes by saying somethingThe illocutionary point of the representatives is to commit the speaker to something's being the case, to the truth of what has been said, in other words, when performing an illocutionary act of representative, the speaker is making a statement or giving a description which he himself believes to be true. Stating, believing, sweating, hypothesizing are among the most typical of the representatives.Directives ate attempts by the speaker to get the hearer to do some- thing. Inviting, suggesting, requesting, advising, wanting, threatening and ordering are all specific instances of this class.Commissives are those illocutionary acts whose point is to commit the speaker to some future course of action, i.e. when speaking the speaker puts himself under a certain obligation.Promising, undertaking, vowing are the most typical ones.The illocutionary point of expressives is to express the psychological state specified in the utterance. The speaker is expressing his feelings or attitudes towards an existing state of affairs, e.g. apologizing, thanking, congratulating.The last class “declarations” has the characteristic that the successful performance of an act of this type brings about the correspondence between what is said and reality.3. What are the four maxims of the CP? Try to give your own examples to show how flouting these maxims gives rise to conversational implicature?答： Cooperative Principle, abbreviated as CP. It goes as follows:Make your conversational contribution such as required at the stage at which it occurs by the accepted purpose or direction of the talk exchange in which you are engaged.To be more specific, there are four maxims under this general principle:(1) The maxim of quantity① Make your contribution as informative as required (for the current purpose of theexchange).② Do not make your contribution more informative than is required.(2) The maxim of quality① Do not say what you believe to be false.② Do not say that for which you lack adequate evidence.(3) The maxim of relationBe relevant.(4) The maxim of manner① Avoid obscurity of expression.② Avoid ambiguity.③ Be brief (avoid unnecessary prolixity).④ Be orderly.。

化学专业英语期末复习备考(三)

化学专业英语期末备考知识汇编（三）三、有机化合物（一）烷烃（alkane）：命名规则规则：1、饱和直链碳氢化合物的命名：①数字词（从penta开始）末端的a去掉加上-ane（methane、ethane、butane、propane除外）。

最长的链用阿拉伯数字由一端起到另一端编号，所选择的方向应使侧链的编号尽可能最低。

当逐个比较具有相同项数的位次(locants)系列时，把最先遇到的不同位次中具有最小编号者，视为“最低的”系列，此原则应用时，不考虑取代基的性质。

eg：戊烷pentane②如果同时存在两个或更多的不同的侧链，中文名称按次序规则排列，英文名称按字母顺序排列：(i)简单的基团：按字母顺序排列，然后插入多倍前缀；例：4-e thyl-3,3-di m ethylheptane 4-乙基-3,3-二甲基庚烷(ii)复杂基的名称以其全名的第一个字母为准。

例：7-(1,2-d imethylpentyl)-5-e thyltridecane7-(1,2-二甲基戊基)-5-乙基十三烷(iii)若复杂基的名称由相同的字母组成，则由复杂基全名中的位次编号决定。

例：6-(1-methylbutyl)-8-(2-methylbutyl)tridecane6-(1-甲基丁基)-8-(2-甲基丁基)十三烷③如果两个或更多的侧链位置相同，则将名称中字母在前的侧链，给予较低的编号，如：4-e thyl-5-m ethyloctane 4-乙基-5-甲基辛烷4-i sopropyl-5-p ropyloctane 4-异丙基-5-丙基辛烷④重复的未被取代的基，用相应的倍数词头来表示。

例如：3,3-dimethylpentane 3,3-二甲基戊烷⑤若干个取代方式相同复基可用相应的倍数词头——双(bis-)、三(tris-)、四(tetrakis-)、五(pentakis-)等——来表示。

这样的侧链全名可放在括号中或用带撇的数字来表明侧链中的碳原子，例如：(a)用括号而不用带撇的数字：5,5-bis(1,1-dimetylpropyl)-2-methyldecane5,5-bis(1,1-二甲基丙基)-2-甲基癸烷(b)用带撇的数字：5,5-bis-1',1'-dimethylpropyl-2-metyldecane5,5-双-1',1'-二甲基丙基-2-甲基癸烷(a)用括号而不用带撇的数字：7-(1,1-dimethylbutyl)-7-(1,1-dimethylpentyl)-tridecane7-(1,1-二甲基丁基)-7-(1,1-二甲基戊基)-十三烷(b)用带撇的数字：7-1',1'-dimethylbutyl-7-1,1-dimethylpentyltridecane7-1',1'-二甲基丁基-7-1,1-二甲基戊基十三烷⑥在一个饱和支链无环烃中，若有相同长度的链可作为主链，则选择顺序为：(a)具有侧链数目最多的链，例如：2,3,5-trimethyl-4-propylheptane 2,3,5-三甲基-4-丙基庚烷(b)侧链具有最低位次的链，例如：4-isobutyl-2,5-dimethylheptane 4-异丁基-2,5-二甲基庚烷(c)所含较小侧链的碳原子数目最多的链。
