被動語態有哪些正確的使用方法
被動語態是動詞的一種形式，用以說明主語與謂語動詞之間的關系，掌握被動語態的使用方法非常重要。以下是由學習啦小編整理的被動語態的用法內容，希望大家喜歡!
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
例A new cinema is being built here.
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.
使用被動語態的方法
學習被動語態時，不僅要知道被動語態的各種語法結構，還要知道在哪些情況中使用被動語態。
1. 講話者不知道動作的執行者或不必說出動作的執行者 (這時可省 by 短語)。
例 My bike was stolen last night.
2. 借助被動的動作突出動作的執行者。
例 I was given ten minutes to decide whether I should accept the offer.
3. 為了更好地安排句子。
例The well-known person got on the bus and was immediately recognized by people. (一個主語就夠了)
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。

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。
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。
