英语八大构词法及举例

英语八大构词法及举例文章一:英语八大构词法及举例英语是一种十分复杂的语言,同时也是构词能力最为强大的语言之一,它的构词能力源于其采用的不同构词法。
构词法是指语言使用何种方式构成词汇,英语语言中共有八种构词法,如下:1. 仿形构词法:是语言中最古老的构词形式,它以类似的音节相互组合形成新的词汇,是最常见的构词方式,如:rain(雨)→rainy (多雨的);man(男人)→manly(男子气的)。
2. 合成构词法:是将两个或两个以上的词组合成一个词的构词方式,构成的新词有其独立的语义,如:book(书)+case(箱子)→bookcase(书柜); white+board→whiteboard(白板)。
3. 转换构词法:也叫转型构词法,即将原有单词的词性转换为其他词性来构成新词,如:teach(教)→teacher(教师);night (夜晚)→nightly(每晚的)。
4. 派生构词法:即从原有单词当中分离出一个或几个词根,再根据特殊的语法规则加以构成新的词,如:happy(快乐的)→happiness(快乐);beauty(美丽)→beautiful(美丽的)。
5. 后缀构词法:是将某一个后缀添加到一个单词的尾部,从而构成新的词,如:dark(黑暗)→darken(变暗);happy(快乐)→happiness(快乐)。
6. 前缀构词法:是将某一个前缀加到原有单词的首部,从而构成新的词,如:happy(快乐)→unhappy(不快乐);legal(合法的)→illegal(非法的)。
7. 借词构词法:是指借用他语中的词汇作为英语词汇的来源,如:Alps(阿尔卑斯山)→kaiser(凯撒,皇帝);science(科学)→borracho(醉鬼);cafe(咖啡馆)→tortilla(玉米饼)。
8. 固定结构构词法:是指某些特定的词汇结构,如:is+形容词+enough(够)→enough(够);do+动词+the+形容词+way(方式)→dothe+形容词+way(以…方式做)。

构词法知识要点与练习

Chapter 4 Word FormationPart I:知识要点The expansion of vocabulary in modern English depends chiefly on word-formation.Not all the words that are produced by applying the rules are acceptable.Rules only provide a constant set of models from which new words are created from day to day.现代英语词汇的扩充主要依靠构词法。
并不是所有应用规则产生的单词都是可接受的。
规则只提供了一组固定的模型,从这些模型中可以日复一日地创建新单词。
Rules themselves are not fixed but undergo changes.affixation 30%-40%,compounding 28%-30%,conversion 26%,shortening 8%-10% ,(clipping and acronymy) blending and others 1%-5%1.AffixationAffixation (也叫Derivation):the formation of words by adding word forming or derivational affixes to stems. ( derivative 派生词)According to their position,affixation falls into:prefixation (前缀法)and suffixation (后缀法). I.l. Prefixation ----------- t he formation of new words by adding prefixes to stems. Itdoes not change the word-class of the stem but change its meaning.通过在词干上加前缀来形成新词。

高中英语构词法讲解与练习一.类别英语构词法主要有:合成法,转化法,派生法,混成法,截短法和词首字母缩略法。
二.定义与精讲1.转化法英语中,有的名词可作动词,有的形容词可作副词或动词,这种把一种词性用作另一种词性而词形不变的方法叫作转化法。
1)动词转化为名词①很多动词可以转化为名词,大多数情况下,意思没有多大的变化,如:Let's go out for a walk.我们到外面去散散步吧。
②有时意思有一定变化,如:He is a man of strong build.他是一个体格健壮的汉子。
③有的与一个动词和不定冠词构成短语,表示一个动作,如:Let's have a swim.咱们游泳吧。
2)名词转化为动词①很多表示物件,如Did you book a seat on the plane? 你订好飞机座位了吗?②身体部位,如:Please hand me the book.请把那本书递给我。
③某类人的名词可以用作动词来表示动作,如:She nursed her husband back to health.她看护丈夫,使他恢复了健康。
④某些抽象名词也可作动词。
如:We lunched together.我们在一起吃了午餐。
3)形容词转化为动词有少数形容词可以转化为动词。
如:We will try our best to better our living conditions.我们要尽力改善我们的生活状况。
4)副词转化为动词有少数副词可以转化为动词。
例如:Murder will out.(谚语)恶事终必将败露。
5)形容词转化为名词①表示颜色的形容词常可转化为名词,如:You should be dressed in black at the funeral.你在葬礼中该穿黑色衣服②某些形容词如old, young, poor, rich, wounded, injured等与the连用,表示一类人,作主语时,谓语用复数如下,如:The old in our village are living a happy life.我们村的老年人过着幸福的生活。
2.派生法在词根前面加前缀或在词根后面加后缀构成一个与原单词意义相近或截然相反的新词叫作派生法。
1)前缀除少数前缀外,前缀一般改变单词的意义,不改变词性;后缀一般改变词类,而不引起词义的变化。
(1)表示否定意义的前缀常用的有dis-, il-, im-, in-, ir-, mis-, non-, un-等,在单词的前面加这类前缀常构成与该词意义相反的新词。
例如:appear出现→disappear消失correct正确的→incorrect不正确的lead带领→mislead领错stop停下→non-stop不停(2)表示其他意义的前缀常用的有a-(多构成表语形容词), anti- (反对;抵抗), auto- (自动), co- (共同), en- (使), inter- (互相), re- (再;又), sub- (下面的;次;小), tele- (强调距离)等。
例如:alone单独的antigas防毒气的autochart自动图表cooperate合作enjoy使高兴internet互联网reuse再用subway地铁telephone电话2)后缀英语单词不仅可以通过加前缀构成新词,也可加后缀构成新词。
后缀通常会改变单词的词性,构成意义相近的其他词性;少数后缀还会改变词义,变为与原来词义相反的新词。
(1)构成名词的后缀常用的有-ence,-(e)r/ -or (从事某事的人),-ese (某地人),-ess (雌性),-ful (一……),-ian (精通……的人),-ist (专业人员),-ment (性质;状态),-ness (性质;状态),-tion(动作;过程)等。
例如:differ不同于→difference区别write写→writer作家Japan日本→Japanese日本人act表演→actress女演员mouth口→mouthful一口music音乐→musician音乐家(2)构成动词的后缀常用的有-(e)n (多用于形容词之后),-fy (使……化),-ize (使……成为)。
例如:wide→widen加宽beauty→beautify美化pure→purify提纯real→realize意识到organ→organize组织(3)构成形容词的后缀常用的有-al,-able (有能力的),-(a)n(某国人的),-en (多用于表示材料的名词后),-ern (方向的),-ese(某国人的),-ful,-(ic)al,-ish,-ive,-less (表示否定),-like (像……的),-ly,-ous,-some,-y (表示天气)等。
例如:nature自然→natural自然的reason道理→reasonable有道理的America美国→American美国的China中国→Chinese中国人的gold金子→golden金的east东→eastern东方的child孩子→childish孩子气的snow雪→snowy雪的(4)构成副词的常用后缀有-ly (主要用于形容词之后表示方式或程度),-ward(s) (主要用于表示方位的词之后表示方向)。
例如:angry生气的→angrily生气地to到→towards朝……,向……east东方→eastward向东(5)构成数词的后缀有-teen (十几),-ty (几十),-th (构成序数词)。
例如:six六→sixteen十六→sixteenth第十六four四→forty四十→fortieth第四十3.4.截短法(缩略法)截短法,即将单词缩写,词义和词性保持不变,主要有截头、去尾、截头去尾等形式。
1)截头telephone→phoneaeroplane→planeomnibus→bus2)去尾mathematics→mathsco-operate→co-opexamination→examkilogram→kilolaboratory→labtaxicab→taxi3)截头去尾influenza→flurefrigerator→fridgeprescription→script5.混合法(混成法)混合法,即将两个词混合或各取一部分紧缩而成一个新词。
后半部分表示主体;前半部分表示属性。
news broadcast→newscast新闻广播television broadcast→telecast电视播送smoke and fog→smog烟雾helicopter airport→heliport直升飞机场6.首尾字母缩略法首尾字母缩略法,即用单词首尾字母组成一个新词。
读音主要有两种形式,即各字母分别读音;作为一个单词读音。
very important person→VIP (读字母音)要人;大人物television→TV (读字母音)电视Testing of English as a Foreign Language→TOEFL托福三.巩固练习1.
