构词法综述
Word-building
许多英语单词的构成都有一定的规律，这种规律被称为构词法。掌握构词法知识对我们更好地理解词义、认识新词和扩大词汇量有重要意义。英语中的构词法主要有:
合成法(Composition)
转换法(Conversion)
派生法(Derivation)
合成法——综述
一、合成法（Composition ）

把两个或两个以上的词素放到一起，这种构词法称为合成法。合成词通常由两个或两个以上的自由词素构成不同词性。
1. 合成名词
名词+名词： postman, girlfriend,
flowerbed, greenhouse
形容词+名词： blackboard, supermarket
名词+动词： daybreak, sunrise
动词-ing+名词：

ourselves
某些不定代词some, any, every, no等+

名词+动词：moonwalk, sunbathe
形容词+动词：safeguard
Maybe the first plant just made a cry of pain or was sending a message to its own branches, and so, in effect, was talking to itself. Perhaps the neighbors just happened to ‘overhear’ the cry. So information was exchanged. (2017 全国Ⅱ阅读)
转换法——综述
二、转换法（conversion）
在词形不变的情况下，把一个单词由一种词性转换成另一种词性，而没有加任何词缀，这种构词方法称为转换法。例如：

dream v. 做梦 → n. 梦
look v. 看 → n. 相貌
back n. 后背 → v. 支持
air n. 空气 → v. 通风
better a. 较好 → v. 改善
有些双音节的词转换后，重音要发生变化。通常名词重音在前，动词重音在后，有时读音也有不同，应予注意。例如:

transport record import

conflict survey
转换法——名词转换成动词
1. 许多名词可转化成动词，意思也随着有些改变。如：

chair（n.椅子→ v.主持） hand（n.手→v.上交）
land（n.土地→v.着陆） cook（n.厨师→v.烹调）
order（n.命令→v.订购） name（n.名字→v.取名）
lift（n.电梯→v.举起） picture（n.画→v.描绘）
press（n.报刊→v.挤压） nurse（n.护士→v.照料）
smoke（n.烟→v.吸烟） stand（n.看台→v.站）?
转换法——动词转换成名词
2. 大量动词可转化为名词，有时意思没有太大改变。如：

try （v.尝试→n.尝试） read (v.阅读→n.阅读)
swim （v.游泳→n.游泳）sigh (v.叹气→n.叹气）
cry (v.哭→n.哭) shout（v.呼喊→n.呼喊）
kiss (v.吻→n吻) guess (v.猜测→n猜测)
转换法——形容转换成动词
3. 形容词转化成动词。如：

better（a.更好的→v.改善) calm（a.冷静的→v.使冷静）
cool （a.凉快的→v.冷却）spare（a.空闲的→v.节省）
own （a.自己的→v.拥有） close（a.亲密的→v.关闭）
slow （a.慢的→v.减慢）last（a.最后的→v.持续）
I placed the chick(雏鸟) in the nest, and it quickly calmed down. (2017 全国Ⅰ阅读)
转换法——形容词转换成名词和副词
4. 形容词转化成名词。如：

cold（a.冷的→n.感冒） back（a.后面的→n.背部）
quiet (a.安静的→n.恬静) calm (a.平静的→n安静)

5. 形容词转化成副词。如：

deep（a.深的→ad.深地） wide（a.宽的→ad.广泛地）
hard（a.困难的→ad.努力地) well（a.健康的→ad.很好地）
三、派生法(Derivation)
派生是指通过给一个单词加前缀或后缀构成另一个词。前缀一般改变词义而不改变词性, 后缀一般改变词性而不改变词义。
