5. “主+动+宾+宾补”句型变为被动结构这种句型有两个宾语,一般地说一为间接宾语,一为直接宾语。

变为被动结构时,只将主动结构中的一个宾语变为被动结构中的主语,另一宾语不变。

(主动句)He was called Xiao Wang. 他被叫做小王。

(被动句)He painted the table green. 他把桌子漆成了绿色。

→It is said that he is the richest man in the city.据说他是全市头号富翁。

→He is said to be the richest man in the city.据说他是全市头号富翁。

当说话人认为主动句的主语无关紧要,或者不清楚谁是谓语动作的发出者时,便常常使用上述形式的被动句。

如:It was reported that the boy had been found.据报道,男孩已被找到。

The boy was reported to have been found.据报道,男孩已被找到。

常用于上述被动句型的动词有:acknowledge, assume, believe, claim, consider, declare, estimate, expect, find, know, presume, report, say, think等。

7. 含有被动意义的主动语态英语中有一些表示被动意义的主动句,其谓语所表示的不是主语的动作,而是其内在的性能。

如:She is to blame. 她应该受到责备。
