英语中,词的构成方法主要有四种:合成
法、转化法、派生法和缩略法。
1. 合成法:把两个或更多的词合成一个词,可用连字符连接,也可直接写一起,或者由分开的两个词构成。合成词一般包括:合成名词、合成形容词、合成动词等。
构词法
1) 合成名词
名词+名词:
postman, girlfriend, flowerbed, notebook
形容词+名词:
blackboard, supermarket, greenhouse
名词+动词:daybreak, sunrise, haircut
动词-ing形式+名词:
reading room, washing machine
名词+动词-ing形式:
handwriting, papermaking
动词+名词:pickpocket, workroom
动词+副词:breakup
其它形式:get-together, go-between, passer-by
2) 合成形容词
形容词+名词+ed: kind-hearted
形容词+v-ing: good-looking
副词+v-ing: hard-working
名词+v-ing: English-speaking
名词+v-ed: man-made

2. 派生法:在一个词根之前或之后加上一个词缀,构成一个新词,这种构词法叫派生法。单词前加前缀,一般不改变词性,只引起意义上的变化。单词后加后缀,一般意义变化不大,只改变了词性。如:(dis)honest, (il)legal, (ir)regular, fool(ish), farm(er), visit(or)等。
常见前缀 含义/功能 例词
in-, il-, im-, ir-, un-, non-, dis- 表否定或反义 incorrect, illegal, impolite, irrelative, unnecessary, non-smoking, dislike
mis- 错误地 mislead, misunderstand
pre- 在……之前 preschool, preview
re- 再,重新 retell, rewrite
inter- 相互 international, interconnect
常见前缀 含义/功能 例词
a- 的 asleep, alive
en- 使 enrich, enlarge
tele- 远程的 television, telescope
auto- 自动 automatic
co- 共同 cooperate, co-worker
multi- 多 multicultural
kilo- 千 kilogram kilometre
常见名词后缀 含义/功能 例词
-er,-or 表具有特征之人或用于……之物 teenager, cooker,
actor
-ment 表结果、状态 replacement, disappointment,
arrangement
-tion 表状态、行为 examination, condition,
reflection
-hood 表身份、性质、时期 parenthood, brotherhood, childhood

-ist 表主义者、从事某种职业 socialist, guitarist
-ship 表性质、关系 ownership, friendship
常见副词后缀 含义/功能 例词
-ly 表示方式 carefully, quickly

-ed 表具有 interested, aged
-ful 表有可……性质的,充满……的 useful, mouthful, painful, colourful
-less 表示无、没有 careless, useless
-able 表示可……的,有……性质的 usable, comfortable
3. 转化法:有些名词可作动词,有些形容词可作动词、名词或副词。这种保持词形不变,但改变词性的方法叫转化法。
1) 动词转化为名词
有些词在转化过程中词义变化不大,如attempt, laugh。有些动词转化为名词时意义有一定的变化,如:
tear(v. 撕开→ n. 泪水),
record(v. 记载,录制→ n. 记录)。
Let’s talk about it. 咱们谈谈这件事吧。
I think we’d better finish the talk now.
我想我们现在最好结束谈话。
2) 名词转化为动词
face n. 脸→ v. 面对 nurse n. 护士→ v. 护理
water n. 水→ v. 浇水
e.g. She gave me a glass of water. 她给了我一杯水。
You should water the flowers twice a week.
你应该每周给这些花浇两次水。
3) 形容词转化为动词、名词或副词
narrow adj. 窄的→ v. 使……变窄
red adj. 红色的→ n. 红色
brif adj. 简短的→ n. 摘要,概要
fast adj. 快的→ adv. 迅速地
e.g. She is wearing a black dress. 她穿着一条黑色的裙子。
The girl in black is very beautiful.
那个穿黑衣服的女孩很漂亮。
Tom is a brave man. 汤姆是一个勇敢的人。
He always braves the difficulties in life.
他一直勇敢地面对生活中的困难。
4) 其它情况的转化,如
head(n. 头 → v. 朝某方向行进),north(adj. 北方的→ adv. 向北)。
4. 缩略法:用单词或短语的部分内容指代整体。
1) 首字母缩写
WTO – World Trade Organization 世界贸易组织
IOC – International Olympic Committee 国际奥林匹
克委员会
OPEC – Organization of Petroleum Exporting
Countries 石油输出国组织
2) 单词截断
advertisement – ad
laboratory – lab

Complete the passage with the help of word formation and get the main idea of each paragraph.
When you open a dictionary, you often come across a lot of unfamiliar words. You might think this is a bit scary. But many of them are formed using other simpler words. This is called word formation.
What is called word formation.
Words formed by combining other words are called compounds, for example, __________ (a friend that you contact by writing, traditionally using a pen) and ____________ (known by many people).
penfriend
well-known
What are called compounds and some examples.
Prefixes and suffixes often have fixed meanings. If you add un- or in- to a word, the new word usually means opposite. For example, if something isn’t correct it’s _________, and if someone isn’t happy they’re _________. Words with the suffixes -ment and -ness are often nouns. For example, if somebody has improved a lot, they have made great ______________.
incorrect
unhappy
improvement
Prefixes and suffixes often have fixed meanings.
Some nouns and adjectives can be used as verbs, or the other way round. When we calm somebody down, they become ________. And we can give someone a present by ____________ it.
calm
presenting
The part of speech can be changed.
And sometimes a word is made up of the first letters of several words: “World Trade Organization” can be referred to as ________, and ________ is short for “as soon as possible”.
It is impossible to know the meaning of every word, but knowing about word formation can help us guess their meanings.
WTO
ASAP
Abbreviating
