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：表示一种 “动作”、“行为” Did you book a seat on the plane? 你订好飞机座位了吗?
Please hand me the book.请把那本书递给我。 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。
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：
1
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

mathematics→maths co-operate→co-op examination→exam kilogram→kilo laboratory→lab taxicab→taxi 3)截头去尾 influenza→flu

5.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。
