7) shall/will be done 一般將來時
例Hundreds of jobs will be lost if the factory closes.
8) should/would be done 過去將來時
例The news would be sent to the soldier's mother as soon as it arrived.
9) shall/will have been done 將來完成時(少用)

2. 被動語態的特殊結構形式
1)帶情態動詞的被動結構。其形式為:情態動詞 be 過去分詞。
例The baby should be taken good care of by the baby-sitter.
2) 有些動詞可以有兩個賓語,在用于被動結構時,可以把主動結構中的一個賓語變為主語,另一賓語仍然保留在謂語后面。通常變為主語的是間接賓語。
例His mother gave him a present for his birthday. 可改為 He was given a present by his mother for his birthday.
3) 當“動詞 賓語 賓語補足語”結構變為被動語態時,將賓語變為被動結構中的主語,其余不動。
例Someone caught the boy smoking a cigarette. 可改為The boy was caught smoking a cigarette.
4)在使役動詞have, make, get以及感官動詞see, watch, notice, hear, feel, observe等后面不定式作賓語補語時,在主動結構中不定式to要省略,但變為被動結構時,要加to。
例Someone saw a stranger walk into the building. 可改為A stranger was seen to walk into the building.
5) 有些相當于及物動詞的動詞詞組,如“動詞 介詞”,“動詞 副詞”等,也可以用于被動結構,但要把它們看作一個整體,不能分開。其中的介詞或副詞也不能省略。
例The meeting is to be put off till Friday.
3. 非謂語動詞的被動語態
v. ing 形式及不定式 to do 也有被動語態(一般時態和完成時態) 。
例I don't like being laughed at in the public.
