Their languages were Celtic. 现在所指最早的居民是凯尔特人,他们的语言仍然是印欧语系的另一分支凯尔特语的方言(2)The second major language known in England was the Latin of the Roman Legions. In 55-54 B.C., the Romans invaded the British Isles英国的第二种主要语言是罗马军团的拉丁语,在公元前55到54年,罗马人入侵英伦群岛(3)

25、glish did not borrow as heavily from Latin or other languages in this period as they did later古代英语的使用者并不像他们后来做的那样大量从拉丁和其他语言借词(3)The common practice was to create new words by combining two native words.handbook通常情况用组合两个本地词的形式来创造新词(4)many Scandinavian words came into the English language许多斯堪的纳维亚词汇进入了

26、英语(5)it was a high inflected language with complex endings它是高度转折的语言正象现代的德语5.Middle English (1150-1500):retaines much fewer inflections(1)The Norman conquest started a continual flow of French words into English诺曼征服开始了法国词汇不断进入英语的洪流(2)The situation of three languages(Latin,French,English)existing simu

28、dings. 如果我们说老英语是一种拥有完整结尾的语言,中世纪英语是一个水平结尾。6.Modern English (1500-up to now): (1)Early(1500-1700)(2)late (1700-up to the present)(1)In the early period of Modern English,known as the Renaissance,many new words taken by scholars from Latin and Greek entered into English许多是学者从拉丁文和希腊文中提取(2)Latinate flavo

29、ur of Modern English现代英语的拉丁风格。(3)In the mid-seventeenth century,English absorbed words from all major languages of the world在十七世纪中期,英语从所有世界的主要语言中吸收词汇。(4)Since the beginning of 20th century,more words are created by means of word-formation从本世纪初开始,更多的词通过构词法被创造出来English has evolved from a synthetic lan

30、guage(Old English) to the present analytic language.英语已经由合成语言(古代英语)进化为现代分析语言7. Growth of Present-day English Vocabulary three main sources:(1)the rapid development of modern science and technology (45 )现代科学和技术的迅猛发展(2)social, economic and political changes(11 )社会,经济和政治的变化(3)the influence of other cul

31、tures and languages( 24 )其它文化和语言的影响8.Modes of Vocabulary Development(1)Creations: Creation refers to the formation of new words by using the existing materials, namely roots, affixes and other elements. 创造是指新词的构成通过使用现有的材料,也就是说,词根,词缀和其他元素。(2)Semantic change means an old form which takes on a new mean

32、ing to meet the new need. 意义改变意味着一个老的形式获取新含义以便去应对新的需要。(3)Borrowing has played a vital role in the development of vocabulary, particularly in earlier times. 借词曾经在词汇的发展中扮演了至关重要的角色,特别是在早期。(4)Reviving archaic or obsolete words also contributes to the growth of English vocabulary though quite insignifica

33、nt. 恢复的古词或者废弃的词也对英语词汇的成长做出了贡献。尽管收效甚微。Chapter 3 Word Formation I概念:词素、语素、语素变体1.The minimal meaningful units are known as morphemes.the morpheme is the smallest functioning unit in the composition of words.最小的意义单位叫做“词素”。词素是“词语组成中最小的功能单位”。2.Morphemes are abstract units, which are realized in speech by

34、discrete units known as morphs.词素是抽象的单位,在话语中被认知通过分开的单位,这单位叫做“语素”。They are actual spoken , minimal carriers of meaning. 它们实际上是能发音的最小的意义载体。The morpheme is to the morph what a phoneme is to a phone.语素是一个音素发音的词素。3. Morphemes coincide with words as they can stand by themselves and function freely in a se

35、ntence .they are called monomorphemic words.语素与词相同,由于它们能代表含义而且能够在句子中自由起作用。这种词叫做单一语素词4. Morphemes which are realized by more than one morph according to their position in a word. Such alternative morphs are known as allomorphs.一些词素被按照语素在其中排列而认识,那些替换的语素被称为”语素变体”。5.the morpheme of plurality |-s:tpk后面(-

36、s)、dbgl后面(-z)、iz是在sz J, 3, tj, C13之后the past tense过去形式 simple present 一般现在时 possessive 所有格 comparative or superlative degrees 比较级和最高级6.(1)Free Morphemes(自由词素): have complete meaning in themselves and can be used as free grammatical units in sentences. A free morpheme is one that can stand by itself.

37、 (which are independent of other morphemes are considered to be free). 不依靠其他语素的语素是自由语素。这些语素自己有完整的意义可以在句子中当作自由的语法单位来使用。(2)Bound Morphemes(粘着语素): A bound morpheme is one that cannot stand by itself. They are bound to other morphemes to form words. Bound morphemes are chiefly found in derived words. +例

38、子 不能作为独立词出现的语素是粘连语素。这样称呼因为它们粘连其他语素去构成单词。粘连语素主要出现在派生词中。7. -ist“的实践者”; -al表示“的,关于的”, -ize表示使成为;-ation表示: “动作”,“过程”, -ic与有关的8. Bound Morpheme includes two types: (1) bound root(粘附词根) +例子 (2)Affix(词缀)(1) a bound root is that part of the word that carries the fundamental meaning just like a free root. Un

39、like a free root, it is a bound form and has to combine with other morphemes to make words. 一个粘连词根是词中承担基础意义的部分,如同自由根词。和自由根词不同的是,他是一个粘连形式不得不与其他词素组合来构成单词。In English, bound roots are either Latin or Greek. Although they are limited in number, their productive power is amazing.(2)Affixes are forms that

40、are attached to words or word elements to modify meaning or function.词缀是附属在单词上或者单词元素上以修改词语意义和功能的结构。9. Affixes can be put into two groups:1)Inflectional affixes (屈折词缀):affixes attached to the end of words to indicate grammatical relationships are inflectional,thus known as inflectional morphemes. 是附加

41、在词尾用来表示屈折关系,因此被称为“屈折词素”。2)Derivational affixes(派生词缀): derivational affixes are affixes added to other morphemes to create new words. 派生词缀是加在其他语素上建立新词的词缀。派生词缀可以分为前缀和后缀。Prefixes come before the word and the suffixes after the word10. A root is the basic form of a word which cannot be further analysed

42、without total loss of identity. 词根是一个词的基础形式不能在没有丧失定义的前提下继续分解. In terms of derivational and inflectional morphology, a root is that part of a wordform that remains when all inflectional and derivational affixes have been removed. 根据派生和屈折语形学,“一个词根是词语中去除所有屈折词缀和派生词缀都去除剩下的部分。11. A stem can be defined as

43、a form to which affixes of any kind can be added. 词干可以被定义为任何词缀都能够添加的形式。Chapter 4 Word-Formation II(构词法)1.The expansion of vocabulary in modern English depends chiefly on word-formation现代英语中词汇的扩张只要依靠构词法2. 构词法分类:affixation (30%-40%) 词缀法( 30 -40 )compounding (28%-30%) 复合法( 28 -30 )conversion (26%) 转化法(

44、 26 )shortening (8%-10%) 缩略法 ( 8 -10 )blending and other means (1%-5%) 拼缀法和其他方法( 1 -5% )3. Affixation is generally defined as the formation of words by adding word-forming or derivational affixes to stems. This process is also known as derivation, for new words created in this way are derived from o

45、ld forms. The words formed in this way are called derivatives. 词缀法通常被认为是通过添加词形或者派生词缀到词干以构成新词的方法。这个过程也被称作“派生”,因为通过这种方式创造的新词是从旧词派生而来。通过这种方式造出的词叫做“派生词”。4. affixation falls into two subclasses: prefixation and suffixation.(1)Prefixation is the formation of new words by adding prefixes to stems. Prefixes

46、 do not generally change the word-class of the stem but only modify its meaning. 前缀法通过给词干加前缀来构成新词。前缀通常不改变词干的词类但是只改变它的意思。The majority of prefixes are characterized by their non-class-changing nature. Their chief function is to change meanings of the stems. 前缀的大多数都以不改变词类的特点为特征。它们的主要功能是改变词干的意义。(2)Suffi

47、xation is the formation of new words by adding suffixes to stems. Unlike prefixes which primarily change the meaning of the stem, suffixes have only a small semantic role, their primary function being to change the grammatical function of stems. 后缀法是通过添加后缀到词干来构成新词的方法。不象前缀主要改变词干的意思,后缀只有一个很小的意义作用,它们的主

48、要作用是改变词干的语法功能。we shall group suffixes on a grammatical basis into noun suffixes, verb suffixes, adjective suffixes我们可以根据语法基础将后缀分为名词后缀,动词后缀,形容词后缀,等等后缀的类别Deverbal动词派生Denominal名词派生 需要记5. Compounding, also called composition, is the formation of new words by joining two or more stems. Words formed in th

49、is way are called compounds. 复合词也叫组合词,是通过连接两个以上词干构成新词的方式。通过这样的方式构成的词叫复合词。三个特征:(1)Phonetic features(exceptions:sociolinguistics,psycho-analysis)(2)Semantic features:a lot of compounds are transparent许多复合词是意义明确的(3)Grammatical features6. Compounding can take place within any of the word classes, but th

50、e productive ones are nouns and adjectives followed by verbs to a much lesser extent复合适用于任何词类,但是最具生产力的是名词和形容词后跟动词,这样程度更小。7.Formation of compounds复合词组成(1)Noun compounds(名词)(2)Adjective compounds(形容词)各11种需了解(3)Verb compounds(conversion or backformation)8.conversion(zero-derivation零派生)Conversion is the

51、 formation of new words by converting words of one class to another class. 转换法是通过转换词类到另一词类的构成新词方法Since the words do not change in morphological structure but in function, this process is also known as functional shift. 由于词没有改变形态但是改变了功能,这个过程被称为“功能转换”。Conversion is generally considered to be a derivat

52、ional process whereby an item is adapted or converted to a new word class without the addition of an affix. Hence the name zero-derivation反转通常被认为是一个派生的过程,一个词条被改变或者反转成为新词类,没有添加词缀。因此叫做“零派生”。Words produced by conversion are primarily nouns, adjectives, and verbs. 通过反转产生的主要是名词,形容词和动词。conversion is not o

53、nly a change of grammatical function of the lexical item involved but with it the different range of meaning that it originally carried转换不仅是词条语法功能的转换,而且因为转换出现不同的语意范围,和原来承载的不同。9. In some cases, conversion is accompanied by certain changes which affect pronunciation or spelling or stress distribution.

54、 The most common changes are:(1)Voiceless to voiced consonant(2) Initial to end stress在某些情况下,反转被增加一定的变化,这些变化会影响读音或者拼写或者重音的分布。最常见的变化是:+例子(1)不发音的辅音变成发音的辅音。(2)开始重音到结束重音。10. Blending is the formation of new words by combining parts of two words or a word plus a part of another word. Words formed in this

55、 way are called blends or pormanteau words. 混合词是组合两个词的一部分或者一个词加上另一词的一部分来构词的方法。通过这种方式构造的词称作“混合词”或拼级词。+例子1) head + tail 头尾2) head + head 头头3) head + word 头整词4) word + tail 整词尾11. Another common way of making a word is to shorten a longer word by cutting a part off the original and using what remains i

56、nstead. This is called clipping另一种造词的常见方式是缩短一个长词,用减去原词一部分,使用剩下部分的方法。这叫删减。+例子1) Front clipping 前删2) Back clipping 后删3) Front and back clipping 前后删4) Phrase clipping 删短语12. Acronymy is the process of forming new words by joining the initial letters of names of social and political organizations or spe

57、cial noun phrases and technical terms. Words formed in this way are called initialisms or acronyms, depending on the pronunciation of the words. 首字母缩略法是构成新词的过程,通过连接社会和政治组织或者特别名词短语和技术术语的首字母。通过这种方式建成的词叫做首字母缩略法和首字母拼音法,依赖词语的发音。13. Initialisms are words pronounced letter by letter. In cases likeA.D. (Ann

58、o Domini = in the year after the birth of Jesus Christ),B.C. (Before Christ) and C.O.D. (cash on delivery) 缩略词是字母挨个发音的词14. Acronyms are words formed from initial letters but pronounced as a normal word, for example radar (radio detecting and ranging), and WAVES (Women Appointed for Voluntary Emergen

59、cy Service), etc首字母缩写词是从首字母构成,但是发音是正常词15. Back-formation is considered to be the opposite process of suffixation. As we know, suffixation is the formation of new words by adding suffixes to bases, and back-formation is therefore the method of creating words by removing the supposed suffixes. 逆构法被认为是

60、后缀法的相反过程。如我们所知,后缀法是通过加后缀到基础的构词方式,逆构法因此就是通过消除假想的后缀的方法来构词的方式。16. Words created through back-formation are mostly verbs. There are only a few that can be used as nouns or as both nouns and verbs通过逆构法构成的词大多数是动词, 只有少数可以被当成名词使用,或者同时当作名词和动词。Chapter 5 Word Meaning 1.Words are but symbols, many of which have

61、 meaning only when they have acquired reference词语只是符号,许多只当它们获得参考的时候才有意义。1.Reference(所指):It is the relationship between language and the world. The reference of a word is arbitrary and conventional. It is a kind of abstraction, yet with the help of context, it can refer to something specific. 参考是语言和世

62、界之间的联系。其是任意且约定俗成的。尽管参考是一种抽象,然而在背景的帮助下,它能指示特定的事物。The connection is a result of generalization and abstraction。它是一般化和抽象化的结果。2.Concept(概念):which is beyond language, is the result of human cognition(认识),reflecting the objective world in the human mind.。概念,是在语言之外,是人类认识的结果,反映人心中的客观世界。3.Meaning and concept

63、 : They are both related directly to referents and are notions of the words but belong to different categories. 它们都是直接和参照物联系,而且是词的概念但是属于不同的种类。Meaning so is restricted to language use.意义仅限于语言的使用。4.Sense:It denotes the relationship inside the language. The sense of an expression is its place in a syst

64、em of semantic relationships with other expressions in the language. “语感”表示语言内部的关系。“表达的感觉是它在一套语意关系中的位置,和其他表达相对而言。5.Sense and Reference:Unlike reference, sense denotes the relationships inside the language. The sense of an expression is its place in a system of semantic relationships with other expre

65、ssions in the language. (ibid) Since the sense of an expression is not a thing, it is often difficult to say what sort of identity it is. It is also an abstraction. Every word that has meaning has sense (not every word has reference). 不像参考,“语感”表示语言内部的关系。“表达的感觉是它在一套语意关系中的位置,和其他表达相对而言。由于表达的感觉不是具体事物,因此很难说它属于哪种定义
