初中英语知识点总结
被动语态的特殊结构形式
1)带情态动词的被动结构。其形式为：情态动词+be+过去分词。
例The baby should be taken goodcare of by the baby-sitter.
2) 有些动词可以有两个宾语，在用于被动结构时，可以把主动结构中的一个宾语变为主语，另一宾语仍然保留在谓语后面。通常变为主语的是间接宾语。
例His mother gave him a presentfor his birthday. 可改为 He was given a present by his mother for his birthday.
3) 当“动词+宾语+宾语补足语”结构变为被动语态时，将宾语变为被动结构中的主语，其余不动。
例Someone caught the boy smokinga cigarette. 可改为The boy was caught smoking a cigarette.
4)在使役动词have, make, get以及感官动词see, watch, notice, hear, feel,observe等后面不定式作宾语补语时，在主动结构中不定式to要省略，但变为被动结构时，要加to。
例Someone saw a stranger walkinto the building. 可改为A stranger was seen to walk into the building.
5) 有些相当于及物动词的动词词组，如“动词+介词”，“动词+副词”等，也可以用于被动结构，但要把它们看作一个整体，不能分开。其中的介词或副词也不能省略。
例The meeting is to be put offtill Friday.
3. 非谓语动词的被动语态
v.+ing 形式及不定式 to do 也有被动语态(一般时态和完成时态) 。
