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。

His mother gave him a present for his birthday. 可改为 He was given a present by his mother for his birthday.

将宾语变为被动结构中的主语，其余不动。

Someone caught the boy smoking a cigarette. 可改为The boy was caught smoking a cigarette.

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。

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。
