三、重点语法 词的转化---名词用作动词

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.
