30、 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 impossi
31、ble, 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, -or teacher, worker, visitor -ian musician -ing building, painting, shopping, mean
32、ing -ist artist, scientist -ment agreement, government -ness coldness, happiness, illness -th truth, warmth -tion competition, education, information, invitation -ty 构成名词 activity, safety -ble, ible comfortable, eatable, enjoyable, possible, probable -al environmental, international, national, tradi
33、tional -ful careful, helpful, useful -ive active, expensive -less 构成形容词 careless, helpless, homeless, useless -ly friendly, lovely, monthly, weekly -ous dangerous, famous -teen eighteen, fifteen, seventeen -th fifteenth, fifth, fortieth, seventh -ty 构成数词 forty, sixty, twenty -ly 构成副词 badly, carefull
34、y, 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 interesting interestingly interested uninterested 由 help 可以派生出： helpless 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
35、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 Lets talk about it more. 咱们再谈谈这件事吧。 I think wed better finish the talk now. 我想我们最好现在结束谈话。 (2) 名词转化为动词 She gave me a cup of water. 她给了我一杯水。 You should water the flowers twice a day. 你应该每天给这些花浇两次水。 (3) 形容词转化为名词 She was wearing a black dress. 她穿着一条黑色的裙子。
