被動語態的用法
1. 被動語態的基本時態變化
被動語態通常為十種時態的被動形式, 被動語態由be 過去分詞構成，be隨時態的變化而變化。以do為例，各種時態的被動語態形式為：
1*** am/is/are done ***過去分詞*** 一般現在時
例Visitors are requested not to touch the exhibits.
2*** has /have been done 現在完成時
例All the preparations for the task have been completed, and we're ready to start.
3*** am/is /are being done 現在進行時

4*** was/were done 一般過去時
例I was given ten minutes to decide whether I should reject the offer.
5*** had been done 過去完成時
例 By the end of last year, another new gymnasium had been completed in Beijing.
6*** was/were being done 過去進行時
例A meeting was being held when I was there.
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***
例The project will have been completed before July.
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，在用於被動結構時，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後面。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，其餘不動。
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等後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*** 有些相當於及物動詞的動詞片語，如“動詞 介詞”，“動詞 副詞”等，也可以用於被動結構，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.
