(2) 常见后缀 后缀功能例词-er, -or 构成名词teacher, worker, visitor-ianmusician-ingbuilding, painting, shopping, meaning-istartist, scientist-mentagreement, government-nesscoldness, happiness, illness-thtruth, warmth-tioncompetition, education, information, invitation-tyactivity, safety-ble, ible构成形容词comfortable, eatable, enjoyable, possible, probable-alenvironmental, international, national, traditional-fulcareful, helpful, useful-iveactive, expensive-lesscareless, helpless, homeless, useless-lyfriendly, lovely, monthly, weekly-ousdangerous, famous-teen构成数词eighteen, fifteen, seventeen-thfifteenth, fifth, fortieth, seventh-tyforty, sixty, twenty-ly构成副词badly, carefully, 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 — Let’s talk about it more. 咱们再谈谈这件事吧。 — I think we’d 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。 The girl in black looks very beautiful. 那个穿黑衣服的女孩看上去很漂亮。 Step 5 Homework Finish the exercise paper.
