Look at the sentences and expressions from the reading passage. Match the words in red to the types of word formation.
Now look for more examples of each type in the reading passage.
1. abbreviating: IT, US
2. changing the part of speech: When we … see… snow, we can say… “it’s snowing”.
3. adding a prefix or suffix: paint-painting, hard-hardly, soft-softly, harm-harmless/harmful, shame-shameless/shameful, visible-invisible
4. combining two or more words: hamburger, eggplant, seasick, airsick, carsick, homesick, homework, housework
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：把两个或两个以上的独立且语义不同的单词合成一个新词，构词方式比较灵活。合成词一般包括：合成名词、合成形容词、合成动词等。
构词法 (Word formation)
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
副词+v.-ed: well-known
形容词+名词: mid-east, round-trip
3) 合成代词
代词宾格/物主代词+ self / selves：herself, ourselves
某些不定代词some, any, every, no等+ body /one / thing：anyone, nothing
4) 合成介词
介词+副词：within
副词+名词：outside
5) 合成副词
副词+名词：indoors, overhead, upstairs
介词+名词：alongside, beforehand
名词+形容词：sky-high
副词+介词：nearby
其它形式：meanwhile, headfirst
6) 合成动词
副词+动词：overhear, overwork, underline
名词+动词：moonwalk, sunbathe
形容词+动词：whitewash, safeguard
pop
corn
rain
bow
sun
glasses
moon
light
sunflower
starfish
=
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- 在……之间；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 （做某事）的人或用于……之物 teenager, cooker, actor
-ment 表结果、状态、动作 replacement, development,
arrangement
-tion 表结果 relation, 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 表技能、地位、性质、关系 ownership, friendship
常见形容词后缀 含义/功能 例词
-ed 表具有 interested, aged
-ful 表有……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
常见副词后缀 含义/功能 例词
-ly 表示方式 carefully, quickly
3. 转化法：把一种词性转化为另一种词性，词性不变。转化后的词义可以通过原词义推断出来。
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）。
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
head（n. 头 → v. 朝某方向行进）
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。
He headed for the bus stop.
他朝着公共汽车站走去。
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
fast adj. 快的→ adv. 迅速地
e.g. The stairs were very narrow. 楼梯非常狭窄。
He narrowed his eyes and gazed at the horizon.
他眯起眼睛凝望着地平线。
We painted the door bright red. 我们把门漆成鲜红色。
I like the way the artist uses red in this painting.
我喜欢画家在这幅作品中对红色的运用。
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

Noah Webster was an American lexicographer renowned for his American Dictionary of the English Language and his contribution to American English. Webster played a significant part in defining the words that Americans use, and adopted many American English spellings in his dictionary, for example, “color” and “center”. He also added commonly used American words that were not part of the British English dictionaries, such as “squash”. He believed that spelling, grammar, and language usage should be based upon and reflect people’s ways of life, enabling those living in different parts of America to communicate in a common language.
