Step5构词法

1.合成法

将两个或两个以上独立且语义不同的单词合在一起构成新词的方法叫做合成法。合成法是一

种比较灵活的构词方法，可以合成名词、形容词、副词、代词、动词等。例如:afternoon,sportsman,

blackboard,sportsperson,newspaper,

airplane,classmate,grandfather等就是通过合成构词法构成的名词；kind-hearted,middle-aged,

hard-working等为合成形容词；however,maybe,himself,everyone,nothing,overlook等也都是

通过合成法构成的单词。

2.派生法

通过在词根前面加前缀或在词根后面加后缀构成一个新词的方法叫作派生法。要通过派生法

理解和记忆单词，我们需要掌握常见的前缀和后缀及派生规律。

(1)常见前缀

前缀含义例词

dis-不disagree,dislike

en-使……处于某种状态enable,enrich

im-,in-不impossible,impatient,inexpensive

inter-在……之间，相互international,interconnect

mis-错误地mislead,misunderstand

non-不，非non-smoker,non-native

re-再，重复rewrite,retell

un-不unable,unhappy,unpopular

(2)常见后缀

后缀功能例词

-er,-orteacher,worker,visitor

-ianmusician

-ingbuilding,painting,shopping,meaning

-ist构成名词artist,scientist

-mentagreement,government

-nesscoldness,happiness,illness

-thtruth,warmth

-tioncompetition,education,information,invitation

-tyactivity,safety

-ble,iblecomfortable,eatable,enjoyable,possible,

probable

-alenvironmental,international,national,

构成形容词traditional

-fulcareful,helpful,useful

-iveactive,expensive

-lesscareless,helpless,homeless,useless

-iyfriendly,lovely,monthly,weekly

-OUSdangerous,famous

-teeneighteen,fifteen,seventeen

-th构成数词fifteenth,fifth,fortieth,seventh

-tyforty,sixty,twenty

-iy构成副词badly,carefully,carelessly,happily,quickly

(3)派生规律

由一个词根加上相应的词缀可以派生出名词、形容词、副词等，掌握派生规律对扩充词汇有

很大帮助。例如：

由interest可以派生出：

/uninteresting

interest一interesting一interestingly

interested-uninterested

由help可以派生出：

helpless一helplessly

help^helpful-helpfully

由able可以派生出：

enable

able—unable

ability

\disable

3.转化法

英语构词法中把一种词性转化为另一种词性而词形不变的方法称作转化法。常见的转化有:

(1)动词转化为名词

一Lefstalkaboutitmore.咱们再谈谈这件事吧。

一Ithinkwe，dbetterfinishthetalknow.我想我们最好现在结束谈话。

(2)名词转化为动词

Shegavemeacupofwater,她给了我——杯水。

Youshouldwatertheflowerstwiceaday.

你应该每天给这些花浇两次水。

(3)形容词转化为名词

Shewaswearingablackdress.

她穿着一条黑色的裙子。

Thegirlinblacklooksverybeautiful.

那个穿黑衣服的女孩看上去很漂亮。
