被动语态 一、使用被动语态时应注意的几个问题 5.当句子的谓语为say, believe, expect, think, know, write, consider, report等时，被动语态有两种形式： ①谓语动词用被动语态，动词不定式作主补。 ②用it作形式主语，真正的主语在后面用主语从句来表示。 People know paper was made in China first. →It is known that paper was made in China first. →Paper was known to be made in China first. 类似句型有：It is said/known/suggested/believed/hoped/ thought that ··· 被动语态 二、不能用被动语态的几种情况 1.所有的不及物动词或不及物动词词组不能用于被动语态之中。 2.表示状态的谓语动词，如：last, hold, benefit, contain, equal, fit, join, mean, look like, consist of 等。 3.表示归属的动词，如：have, own, belong to等。 4.表示“希望、意图”的动词，如：wish, want, hope, like, love, hate等。 5.宾语是反身代词或相互代词时谓语动词用主动语态，不能用被动语态。 6.宾语是同源宾语，不定式、动名词等谓语动词不用被动语态。 7.有些动词以其主动形式表示被动意义，特别是当主语是物时，常见的动词有sell, write, wash, open, lock等。 被动语态 三、主动形式表被动意义 1.当feel, look, smell, taste, sound等后面接形容词时；当cut, read, sell, wear, write等词带状语修饰语时；当动词表示“开始、结束、关、停、转、启动”等意义时，用主动形式表示被动含义。 |
