①基本結(jié)構(gòu)：
肯定句式：be +done (及物動(dòng)詞的過去分詞)
如果是不及物動(dòng)詞 + 相應(yīng)的介詞或副詞
否定句式：be +not +done
疑問句式：be動(dòng)詞(情態(tài)動(dòng)詞)放句首
被動(dòng)語態(tài)中的be為助動(dòng)詞，無意義。be可能是am , is , are也可能是was ,were或原形be。
注：☆被動(dòng)語態(tài)的時(shí)態(tài)是由be的時(shí)態(tài)決定的，be是什么時(shí)態(tài)，全句就是什么時(shí)態(tài)，be后面的過去分詞不變。
Eg：
1.The song is liked by young people. (肯定句)
2.The song isn’t liked by young people.(否定句)
3. Is the song liked by young people ?(一般疑問句)
4.Who is the song liked by ?=By whom is the song liked?(特殊疑問句)
②各種時(shí)態(tài)的構(gòu)成(動(dòng)詞以do為例)：
→一般現(xiàn)在時(shí)
動(dòng)詞的被動(dòng)形式：am/is /are done
例句：He is asked to do this.
→一般過去時(shí)
動(dòng)詞的被動(dòng)形式：was/were done
例句：The story was told by her mother.
→一般將來時(shí)
動(dòng)詞的被動(dòng)形式：will /shall be done
Is/are going to
例句：The problem will be discussed tomorrow.
→過去將來時(shí)
動(dòng)詞的被動(dòng)形式：should/would be done
Was/were are going to
例句：He said the trees would be planted soon.
→現(xiàn)在進(jìn)行時(shí)
動(dòng)詞的被動(dòng)形式：am/is/are being done
例句：The novel is being written.
→過去進(jìn)行時(shí)
動(dòng)詞的被動(dòng)形式：was/were being done
例句：At that time the desk was being made.
→現(xiàn)在完成時(shí)
動(dòng)詞的被動(dòng)形式：has/have been done
例句：The house has been built.
→過去完成時(shí)
動(dòng)詞的被動(dòng)形式：had been done
例句：They said that their work had been finished.
含有情態(tài)動(dòng)詞的被動(dòng)語態(tài):情態(tài)動(dòng)詞+be+ done Your homework must be handed in today.
其它幾種特殊句型：
It is said that ……..
It is well known that …….
It is reported that……
例：
①History is made by the people. (一般現(xiàn)在時(shí))
②The cars were made in Tianjin in 1995. (一般過去時(shí))
③The tree will be cut down next year.(一般將來時(shí))
④The room must be kept clean.(含有情態(tài)動(dòng)詞的被動(dòng)語態(tài))
⑤The door is being opened.(現(xiàn)在進(jìn)行時(shí))
⑥The film has been seen by me.(現(xiàn)在完成時(shí))
注：☆不同時(shí)態(tài)的被動(dòng)語態(tài)的差異主要體現(xiàn)在助動(dòng)詞be的變化上,同時(shí)助動(dòng)詞be還要在人稱和數(shù)上與主語保持一致。
③應(yīng)用情況
行為的執(zhí)行者不明確或不必說出來。
Eg: A stranger was killed last night.
用于強(qiáng)調(diào)動(dòng)作的承受者而不是執(zhí)行者。
Eg: The story is told everywhere in the city.
