构词法
把两个或两个以上的词组合在一起或在一个词的基础上进行变化, 从而得到一个新词, 即为“构词”。在初中阶段,我们主要学习三种构词法：合成法、派生法、转化法。
构词法 举例
合成法：把两个或两个以上独立且语义不同的单词合在一起, 构成一个新词, 这种构词法叫合成法。常见的合成词有合成名词、合成形容词和合成动词 home+work-homework
hard+working-hardworking
down+load-download

派生法：派生法也叫前缀、后缀构词法, 即由一个词根加上前缀或后缀构成另一个词的构成方法。 1. 前缀 添加在词根前的构词部分叫前缀, 多数情况下它不改变原 possible-impossible, happy-unhappy, correct-incorrect, agree-disagree, smoker-nonsmoker
build-rebuild, use-reuse, cycle-recycle, write-rewrite
understand-misunderstand
war-antiwar
续表
词的词性。常见的有以下几种： (1)im-, un-, in-, dis-,non-等, 表示否定。 (2)re-, 表示“重复”。 (3)mis-, 表示“错误地”。 (4)anti-, 表示“反对；防止”。 (5)inter-, 表示“相互；交互；在……之间”。 national-international
read-reader, visit-visitor, piano-pianist,
suggest-suggestion, develop-development
care-careful, use-useless, believe-believable
slow-slowly
four-fourth, fourteen, forty
2. 后缀 添加在词根后的构词部分叫后缀, 多数情况下它改变原词的词性。常见的有以下几种：(1)名词后缀：-er, -or, -ist, -tion, -ment等。 (2)形容词后缀：-ful, -less, -able等。 (3)副词后缀：-ly。 (4)数词后缀：-th, -teen, -ty等
续表
转化法：转化法是指将一种词类转化为另一种词类而词形不变。转化后的意义往往与之前的意义联系密切。常见的有动词转化为名词、名词转化为动词、形容词转化为动词 ride v. 骑；乘-n. 骑马；乘车
record n.记录-v.最佳纪录
clear adj.(天气)晴朗的-v. (烟雾等)开始消失
