英语七下第十二单元知识点总结英语七下第十二单元知识点总结英语七下第十二单元主要涉及到三个方面的知识点：过去完成时、过去完成时与一般过去时的区别、宾语从句。

以下将对这些知识点进行总结。

一、过去完成时过去完成时用于表示在过去某个时间点或动作之前已经完成的动作。

它的结构是“had + 过去分词”，常常与表时间的连词before, after, when等连用。

例如：1. I had finished my homework before she arrived.2. We had already booked the tickets when he called.3. Had you seen the movie before yesterday?过去完成时的用法主要有以下几个方面：1. 表示过去某个时间点或动作之前的完成动作。

2. 表示过去某个时间点或动作之前已经开始的动作，强调该动作的持续性或过程。

3. 用于条件句中的虚拟条件从句，表示与过去事实相反的假设情况。

二、过去完成时与一般过去时的区别1. 过去完成时强调在过去某个时间点或动作之前就已经完成的动作，而一般过去时表示在过去某个时间点发生的动作或存在的状态。

例如：I had finished my homework before she arrived. (过去完成时)I finished my homework before she arrived. (一般过去时)2. 过去完成时常与表示过去时间的时间状语连用，而一般过去时则不一定。

例如：I had been to London before. (过去完成时)I went to London last year. (一般过去时)3. 过去完成时常与一般过去时同时出现，表示在过去某个时间点或动作之前已经完成的动作与在过去某个时间点发生的动作之间的先后关系。

例如：He had finished his work when I called. (过去完成时)He finished his work and then I called. (一般过去时)三、宾语从句宾语从句是指作为宾语的从句。

Analyze the following questions and explain them according to the requirement.1.1)Interviewer& interviewee are converses; male & female arecomplementaries; old & young are contraries.2)Complementaries truly represent oppositeness of meaning. They are soopposite to each other that they are mutually exclusive and admit nopossibility between them. The assertion of one is the denial of the other orvice versa. Complementaries are nongradable, and they cannot be used incomparative degrees and do not allow adverbs of intensity like “very”toqualify them.3)Contraries are gradable antonyms. The existence of one is in relation to theother. We can say: A man is rich or very rich and also we can say a man isrich than the other. Contraries are characteristic of semantic polarity. Theseantonyms form part of a scale of values between two poles and canaccommodate a middle ground belonging neither to one pole nor to the other.4)Converses consist of relational opposites. The pairs of words indicatereciprocal social relationships that one of them cannot be used withoutsuggesting the other. It also includes reverse terms, which compriseadjectives and adverbs signifying a quality or verbs and nouns signifying anact or state that reverse or undo the quality, action or state of the other.成考复习资料复习资料2I. 单选题1.

How would you explain the difference between back formation and suffixation? Give examples to illustrate your point.1)Back-formation is considered to be the opposite process of suffixation.2)Suffixation is the formation of new words by adding suffixes to bases.3)Backformation is therefore the method of creating words by removing thesupposed suffixes, so called because many of the removed endings are not suffixes but inseparable parts of the word.4)For example, it is a common practice to add –er, -or to verb bases to formagential nouns.5)Reasonably, people make verbs by dropping the ending such as –or in editor, -arin beggar and –er in butler.3. List different types of associative meaning and define them.1)Connotative meaning refers to the overtones or associations suggested by theconceptual meaning, traditionally known as connotations.2)Stylistic meaning refers to stylistic features, which make them appropriate fordifferent styles.3)Affective meaning expresses the speaker’s attitude towards the person or thing inquestion.4)Collocative meaning consists of the associations a word acquires on account ofthe meanings of words which tend to occur in its environment.4. Explain different types of homonyms with examples.(1)Perfect homonyms are known as absolute homonyms, and they are wordsidentical both in sound and spelling. E.g bear (to put up with) and bear (a kind of fruit)(2)Homographs are words identical only in spelling but different in sound andmeaning, e.g. sow (to scatter seeds) and sow (female adult pig)(3)Homophones are words identical only in sound but different in spelling andmeaning, e.g. dear ( a loved person) and deer (a kind of animal)Ⅳ. Analyze the following questions and explain them according to the requirement.1.What is the difference between homonyms and polysemants?1)Perfect homonyms and polysemants are fully identical with reference to spellingand pronunciation, as both have the same orthographical form but different meanings. This creates the problem of differentiation.2)The fundamental difference between homonyms and polysemants lies in the factthat the former refers to different lexemes which have the same form and the latter the one and same lexeme which has several distinguishable meanings.3)One important criterion by which to differentiate them is ‘etymology’, i.e.,homonyms are descendants of different sources whereas a polysemant is a word of the same source which has acquired different meanings in the course of development.4)The second principal consideration is ‘semantic relatedness’. The severalmeanings of a single polysemous lexeme are related and can be traced back to成考复习资料one central meaning. On the other hand, meanings of different homonyms have nothing to do with one another.5)In dictionaries, a polysemant has its meanings all listed under one headwordwhereas homonyms are listed as separate entries.。

英语词汇学笔记之-----章节部分2010.1.11===================================第一章1. Word —— A word is a minimal free form of a language that has a given sound and meaning and syntactic function.2. There is no logical relationship between sound and meaning as the symbolic connection between them is arbitrary and conventional. E.g. ―woman‖ means ’Frau’ in German，’Femme’ in French and ’Funv ’in Chinese. On the other hand，the same sound /rait/ can mean right，rite and write，though denoting different things，yet have the same sound.3. The difference between sound and form result from 4 major factors.（At least 80%of the English words fit consistent spelling patterns）a）. the internal reason is English alphabet does not have a separate letter to represent each sound in the language.b）. Pronunciation has changed more rapidly than spellingc）. Influence of the work of scribes/printing freezes the spelling of words in 1500d）. Borrowing of foreign language4. Vocabulary —— Vocabulary is most commonly used to refer to the sum total of all the words of a language. It can also refer to all the words of a given dialect，a given book，a given subject and all the words possessed by an individual person as well as all the words current in a particular period of time in history.The general estimate of the present day English vocabulary is over 1 million words.5.Classification of Words—by use frequency，by notion，by origin1）. Basic word stock – the foundation of the vocabulary.1. all national character （most important）– natural phenomenamost common things and phenomena of the human body and relationsworld around us names of plants and animalsaction，size，domain，statenumerals，pronouns，prep. ，conj.2. stability – they donate the commonest thing necessary to life，they are like to remain unchanged. Only relative，some are undergoing some changes. But the change is slow.e.g. arrow，bow，chariot，knight – pastelectricity，machine，car，plane —— now3. productivity – they are mostly root words or monosyllabic words，they can form new words with other roots and affixes.e.g. foot – football，footage，footpath，footer4. polysemy – often possess more than one meaning. Become polysemous.e.g. take to move or carry from one place to anotherto remove5. collocability – quite a number of set expressions，idiomatic usages，proverbial saying and otherse.g. heart – a change of heart，a heart of goldNon-basic vocabulary ——1. terminology – technical termsphotoscanning，hepatitis，indigestion，penicillin，algebra，trigonometry，calculus2. jargon – specialized vocabulary in certain professions.Bottom line，ballpark figures，bargaining chips，hold him back，hold him in，paranoid3. slang —— substandard words often used in informal occasionsdough and bread，grass and pot，beaver，smoky，bear，catch，holler，Roger，X-rays，Certain words are labeled slang because of their usage.4. argot – words used by sub-cultured groupscan-opener，dip，persuadercant，jargon ，argot are associated with，or most available to，specific groups of the population.5. dialectal words – only by speakers of the dialectbeauty，chook，cocky，station，auld，build，coo，hame，lough，bog6. archaisms – words no longer in common use or restricted in use. In older poems，legal document and religious writing or speech.7. neologism – newly created words with new meaning e.g. microelectronics，futurology，AIDS，internet，E-mailold meaning acquired new meaning e.g. mouse，monitor2）. Content word （notional word）– denote clear notions.Functional word （empty word，form word）– do not have notions of their own，express the relation between notions，words and sentences.a. Content words constitute the main body of the English vocabulary are numerous.Functional words are in a small number.b. Content words are growing.Functional words remain stable.c. Functional words do far more work of expression than content words.3）. Native words – are words brought to Britain in the 15 century by the German tribes. Ango-Saxon Words，50，000-60，000What is true of the basic word stock is also true of native world. More are1. neutral in style （not stylistical specific ）2. 2.frequent in use （in academic fields and science French，Latin or Greek are used）（usage 70-90%）Borrowed words （loan words，borrowing）– words taken over from foreign language. 80%According to the degree of assimilation and manner of borrowing，we can bring the loan words under 4 classes.1.Denizens – words borrowed early and now are well assimilated into English language.e.g. port from portus（L）shift，change，shirt，porkcup from cuppa（L）2.Aliens – retained their original pronunciation and spellinge.g. décor（F）blitzkreeg（G）emir，intermez，rowtow，bazaar，rajar，status quo3.translation loans – formed from the existing material in the English language but modeled on the patterns taken from another language.1）. Word translated according to the meaninge.g. mother tough from lingua maternal（L）black humor from humor noirlong time no see，surplus value，master piece2）. Words translated according to the sounde.g. kulak from kyrak（Russ）lama from lama（Tib）ketchuptea4. Semantic loans – their meaning are borrowed from another languagee.g. stupid old dumpnew sassydream old joy and peacepioneer old explorer/person doing pioneering worknew a member of the young pioneerfresh old impertinent，sassy，cheeky++++++++++++++++++++++++++++++++++++++++++++++++++第二章1.Indo-European language family （Europe，the Near East，India）Balto –Slavic Indo-Iranian Italic GermanicPrussian Persian Portuguese NorwegianLithuanian Hindi Spanish IcelandiePolish Italian DanishBulgarian Roumanian SwedishSlovenian French EnglishRussian GermanAlbanian Armenian Celtic HellenicIrish GreekBretonScottish2. History （时间，历史事件，特征）1）Old English （450-1150）totally 50，000-60，000 wordsThe 1st people known to inhabit England were Celts，the language was Celtic.The second language was the Latin of the Roman Legions.The Germanic tribes called angles，Saxons and Jutes and their language，Anglo-Saxon dominated and blotted out the Celtic. Now people refer toAnglo-Saxon as old English.At the end of 6th century，the introduction of Christianity has a great impact on the English vocabulary.The common practice was to create new words by combining two native words.In the 9th century，many Scandinavian words came into English. At least 900 words of Scandinavian are in modern English，our daily life and speech.特点：highly inflected languagecomplex endings or vowel changes （full ending）2）Middle English （1150-1500）English，Latin，FrenchUntil 1066，although there were borrowings from Latin，the influence on English was mainly Germanic. But the Norman Conquest started a continual flow of French words into English.By the end of the 13th century，English gradually come back into public areas.Between 1250 and 150 about 9000 words of French origin come into English. 75% of them are till in use today.As many as 2500 words of Dutch origin come into English.特点：fewer inflectionsleveled ending3）Modern English （1500-up to now）early modern English （1500-1700）late modern English（1700-up to now）The Renaissance，Latin and Greek were recognized as the languages of the Western world’s great literary heritage.The Industrial Revolution was in the mid-17 century. With the growth of colonization，British tentacles began a stretching out of to every corner of the globe，thus enabling English to absorb words from all major languages of the world.After World War II，many new words have been created to express new ideas，inventions and scientific achievements.More words are created by means of word-formation.thousands and thousands of new words have been entered to express new ideas inventions，and scientific achievements.more words are created by means of word-formation.in modern English，word endings were mostly lost with just a few exceptions English has evolved from a synthetic language to the present analytic language.science and technology terms make up about 45% of new words. words associated with life-style constitute of 24% and social and economic terms amount to over 10% .mention should be made of an opposite process of development i.e. old words falling out if use.特点：ending are almost lost.3. Three main sources new words1.The rapid development of modern science and technology2.Social，economic and political changes3.The influence of other cultures and languages4. Three modes of vocabulary development1. Creation – the formation of new words by using the existing materials，namely roots，affixes and other elements. （This is the most important way of vocabulary expansion.）2. Semantic change - an old form which take on a new meaning to meet the new need.3. Borrowing – to take in words from other languages.（particularly in earlier time）4. （Reviving archaic or obsolete）French 30%，Latin 8%，Japanese Italian 7%，Spanish 6%，German Greek 5%，Russian Yiddish 4%++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++第三章1. Morpheme —— A morpheme is the smallest meaningful unit of a language. （The smallest functional unit in the composition of words.）2.Morph—— A morpheme must be realized by discrete units. These actual spoken minimal carriers of meaning are morphs.3.Monomorphenic words – morphemes are realized by single morphs.4.Allomorph——Some morphemes are realized by more than one morph according to their position. Such alternative morphs are allomorphemes. E.g. the morpheme of plurality （-s）has a number if allomorphemes in different sound context，e.g. in cats/s/，in bags/z/，in matches/iz/.5. Free morphemes or Free root —— The morphemes have complete meaning and van be used as free grammatical units in sentences，e.g. cat，walk. They are identical with root words. morphemes which are independent of other morphemes are considered to be free.6. Bound Morphemes —— The morphemes cannot occur as separate words. They are bound to other morphemes to form words，e.g. recollection（re+collect+ion）collect – free morpheme re-and –ion are bound morphemes. （include bound root and affix）Bound morphemes are found in derived words.7. Bound root —— A bound root is that part of the word that carries the fundamental meaning just like a free root. Unlike a free root，it is a bound form and has to combine with other morphemes to make words. Take -dict- for example：it conveys the meaning of ―say or speak‖ as a Latin root，but not as a word. With the prefix pre-（=before）we obtain the verb predict meaning ―tell beforehand‖。

Types of meaning:grammatical ~ & lexical ~; conceptual ~& associative ~(connotative~, stylistic~, affective ~, collocative ~,)Associative meaning : 1) associative meaning is the secondary meaning supplemented to the conceptual meaning. 2)It differs from the conceptual meaning in that it is open-ended and indeterminated. 3)It is liable to the influence of such factors as culture , experience, religion, geographical region, class background,education, etc. 4)Associative meaning comprises four types : connotative, stylistic, affective, and collocative.3. Polysemy is a common feature peculiar to all natural language that one word has two or more senses or meanings. Diachronic approach is an approach to polysemy which studies how a word derived its different meanings from its primary meaning in the course of time.4.同形同音异义关系Homonymy is one of the features of words that a word is different in meaning fromanother, but either identical both in sound and spelling or identical only in sound or spelling with the other Homonyms generally fall into three classes: perfect homonyms (same name); homographs (same spelling) and homophones （some sound）. Perfect homonyms are those words identical both in sound and spelling, but different in meaning, e.g. bear /bea/ (n) a large heavy animal; bear /bea/ (v) to put up with. Homographs are the words identical only in spelling but different in sound and meaning, e.g. saw / / (v) to scatter seeds; sow /sau/ (n) female adult pig. Homophones refer to the words identical only in sound but different in spelling and meaning, e.g. dear /dia/ (n) a loved person;deer /dia/ (n) a kind of animal.5. 同形同音异义词与多义词的区别Perfect homonyms and polysemants are fully identical with regard to spelling and pronunciation. This creates the problem of differentiation. The fundamental difference between homonyms and polysemants lies in the fact that the former refers to different words which happen to share the same form and the latter is the one and same word which has several distinguishable meanings. One important criterion is to see their etymology, i.e. homonyms are from different sources whereas a polysemant is from the same source which has acquired different meanings in the course of development. The second principal consideration is semantic relatedness. The various meanings of a polysemant are correlated and connected to one central meaning to a greater or lesser degree, e. g. neck (See 6.1 Polysemy) . On the other hand, meanings of different homonyms have nothing to do with one another. In dictionaries, a polysemant has its meanings all listed under one headword whereas homonyms are listed as separate entries.6. 同义关系Synonyms are words which share the same or nearly the same meaning with each other but different in sound and spelling. There are absolute synonyms and relative synonyms which result from borrowing, dialects and regional English, figurative and euphemistic use of words, coincidence with idiomatic expressions. There exists the difference between or among synonyms in terms of their denotation, connotation or application. Absolute synonyms or complete synonyms are words which are identical in meaning in all its aspects. Relative synonyms or near-synonyms are similar or nearly the same in denotation, but embrace different shades of meaning or different degrees of a given quality. Sources of Synonyms1) Borrowing 2)Dialects and regional English 3) Figurative and euphemistic use of words 4) Coincidence with idiomatic expressions如何区分同义词？1Difference in denotation2 Difference in connotation 3 Difference in application7.What are the characteristics of antonyms?1) Antonyms are classified on the basis of semantic opposition 2) A word which has more than one meaning can have more than one antonym. 3) Antonyms differ in semantic inclusion. 4) Contrary terms are gradable antonyms, differing in degree of intenisty, so each has its own corresponding opposite.8.上下义关系:Hyponymy deals with the relationship of semantic inclusion. That is, the meaningof a more specific word is included in that of another more general word. Superordinates refer to some general words; subordinates denote those more specific words. Hyponymy can be described in terms of tree-like graphs, with higher-order superordinates above the lower subordinates. But their status either as superordinate or subordinate is relative to other terms. For example, horse, dog, pig are subordinates in relation to animal, but superordinates of mare, hound and boar, Animal itself becomes a subordinate of creature. And creature in turn becomes9.词义变化的种类There are five types of meaning, changes: extension, narrowing, degradation,elevation, and transfer among which extension and narrowing are the most common. Changes in meaning can be accounted for from extra-linguistic factors (historical reason, class reason, and psychological reason) and intra-linguistic factors (shortening, the influx of borrowing, and analogy).10.词义的扩大Extension is a process by which a word with a specialized sense is generalized to covera broader or less词义的缩小Narrowing is a process by which a word of wider meaning acquires a specialized sense；词义的升格Elevation is a process by which a word moves from a derogatory or neutral sense to a neutral and/or appreciative sense；词义的降格Degradation is a process by which a word of reputation slides into a pejorative use,；11.词义的转移Transfer is a process by which a word denoting one thing changes to refer to a differentbut related thing. Paper serves as an example. This word formerly denoted an African plant papyrus, which was once used to make paper. In modern times, paper is made from rags, wood, straw and the like, but the product has retained the same name. There is associated transfer. There are other kinds of transfer, such as, concrete to abstract, abstract to concrete and transfer of sensation. 12.语境的种类:非语言语境。
