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。
The baby should be taken good care of by the babysitter.
(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。
His mother gave him a present for 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。
Someone caught the boy smoking a 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足语时,在主动结构中不定式to要省略,但变为被动结构时,要加to。
Someone saw a stranger walk into 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。
The meeting is to be put off till Friday.
