观察下列句子中划线词的变化，然后加以总结。 1. Hard work leads to success. Work hard and you will succeed. 2. We’ve had two wins so far this season. We’re sure to win. 3. Read the article marked with a star. I have starred the important articles. 4. Would you please help me get some records? Make sure you record the names. 5. Seeing from the top of the hill, we can find the city more beautiful. 总结 构词法包括：合成、派生、转化和缩写简写。这里讲解词的转化和词的派生。 一、 词的转化： 单词从一种词类转化为另一种词类而不发生词形变化。如名词、形容词、副词转化为动词；动词、形容词转化为名词等。 ●有些名词转化成动词后，词义不变。(如例句1) work n.工作→v. 工作 ●有些名词转化成动词后，词义有联系。如名词为动词的结果或承受者等。(如例句2-3) win n. 胜利→v.获胜；star n.星号→v.标上星号 ●有些名词转化成动词后，词义不同。(如例句4) record n.唱片→v.记录 注意：有些词的词性转化后，词的重音或读音发生变化。 二、 词的派生： 通过在词根上加前缀或后缀构成另一个词叫词的派生。本册主要出现了名词加后缀构成形容词的用法。 ●表示肯定含义的后缀：-ful, -ic, -al, -ive, -ous, -able/-ible, -y, -ly (如例句5) ●表示否定含义的后缀：-less 注意：名词加后缀构成形容词的变法： (1)多数名词直接加后缀构成形容词。 (2)以不发音的e结尾的名词，大多要先去掉e加后缀。 (3)双写词尾的辅音字母加后缀。 (4)以辅音字母加y结尾的名词，变y为i再加后缀。(如例句5) 练习 用所给词的正确形式填空。 1. The (star) dishes on the menu are suitable for vegetarians. 2. The experiment (result) in the discovery of a cure for cancer. 3. I never promised to lend you my car: you must be (dream)! 4. I was (question) on the same subject about two weeks ago. 5. The number of people who have cars of their own is (increase). 6. The (environment) protection is a topic widely discussed by people nowadays. 7. Much as we like it, we can’t afford that (expense) sports car. 8. In order to pursue the truth he gave up his (comfort) life when he was young.
