全面回顾被动语态(二)
二、 如何使用被动语态
学习被动语态时,不仅要知道被动语态的各种语法结构,还要知道在哪些情况中使用被动语态。
1. 讲话者不知道动作的执行者或不必说出动作的执行者 (这时可省 by 短语)。
例 My bike was stolen last night.
2. 借助被动的动作突出动作的执行者。
例 I was given ten minutes to decide whether I should accept the offer.
3. 为了更好地安排句子。
例The well-known person got on the bus and was immediately recognized by people. (一个主语就够了)
三、 It is said that+从句及其他类似句型
一些表示据说或相信的动词如believe, consider, expect, report, say, suppose, think等可以用于句型It+be+过去分词+that从句或主语+be+过去分词+to do sth.。有:
It is said that 据说,It is reported that据报道,It is believed that大家相信,It is hoped that大家希望,It is well known that众所周知,It is thought that大家认为,It is suggested that据建议。
例It is said that the boy has passed the national exam. (=The boy is said to have passed the national exam. )
