三、重点语法含义：词的转化（conversion）是英语构词法中的主要方法之一。
它指的是一个词不改变词形，而由一种词类转化成另一种或几种词类。
本模块学习名词转化为动词的用法。
名词转化为动词是现代英语中很普遍的现象，同时也是转化构词中最活跃的一种。
人们经常把名词不加任何改变就当作动词使用。
用法：很多表示物件（如下1）、身体部位（如下2）、某类人（如下3）的名词可以用作动词来表示动作，某些抽象名词（如下4）也可作动词。
例如：1. Did you book a seat on the plane?你订好飞机座位了吗?2. We set sail at dawn and headed for New York.我们在黎明起程，直驶纽约。
3. She nursed her husband back to health.她看护丈夫，使他恢复了健康。
4. We lunched together.我们在一起吃了午餐。
体会更多名词用作动词的例子，看你能准确地理解名词动词化后的词意吗？1. He's always bossing his wife about.2. The escaped prisoner was cornered at last.3. Stop mothering her, she’s 30 years old and can take care of herself perfectly well.4. People were streaming out of the station.5. I did not like the way he eyed me.6. Mr. Smith noons for half an hour every day.7. He doesn't have all ideas of his own. He just parrots what other people say.答案揭晓：1. boss around 颐指气使；把…呼来唤去2. corner 将…逼入困境3. mother 像母亲一般地照料4. stream 涌出；川流不息；蜂拥5. eye 看；定睛地看6. noon 午休7. parrot 学舌；盲目重复或模仿除了名词转化为动词外，还有副词，连词等转化为动词，动词转化为名词，形容词副词等转化 为名词。
