在英语中,谓语动词有两种语态:主动语态和被动语态。在被动语态中,主语的谓语动作的承受者。被动语态的构成是:be + 过去分词。 如果主语是动作的执行者,动词要用主动语态;如果主语是动作的承受者,动词就要用被动语态。 如: (主动句)The slaves built the Great Pyramids long time ago。
主语 谓语 宾语 状语 奴隶们在很久以前修建了大金字塔。（在这个句子中，主语the slaves是动作的执行者，是奴隶们修建了金字塔，所以用主动语态。
） （被动句）The Great Pyramids were built（by the slaves）long timeago。 主语 谓语 by+执行者 状语 大金字塔在很久以前被（奴隶们）修建。
（在这个句子中，主语the Great Pyramids是动作built的承受者，金字塔被修建，所以用被动语态。
） 以动词tell为例（过去时told，过去分词told），以下是几种常用时态的被动语态 主动语态 被动语态 一般现在时 tell am/is/are + told 一般过去时 tell was/were + told 一般将来时 shall/will + tell shall/will be +told 现在进行时 am/is/are + telling am/is/are being + told 过去进行时 was/were + telling was/were being + told 现在完成时 have/has + told have/has been + told 过去完成时 had + told had been + told 将来完成时 shall/will have + told shall/will have been + told 过去将来时 should/would + tell should/would be+ told 过去将来完成时should/would have + told should/would have been + told 。
I was beat by him
结构是：动作的接受者（主语）+被动语态动词（be+动词过去分词，作谓语）+（by+动作的发出者，作宾语） 例子： The meetting has been put off. 会议已被推迟了。 The car was seriously damaged. 汽车受到了严重损坏。 特殊例子： The book can't be found.（如含有情态动词，则是情态动词+be+过去分词） 那本书找不到。 A book was given to him by his teacher./He was given a book by his teacher. 他被老师给了一本书。 He was called Xiao Wang. 他被叫做小王。
主语是动作的发出者为主动语态。主语是动作的接受者为被动语态。 (情态动词)+be+动词过去分词.构成被动语态。 we saw him play football on the playground. He was seen to play football on the playground.(注意：宾语补足语有to时，此时to不能省略） 不及物动词，动词短语和系动词没有被动语态。当宾语是不定式时，很少用被动语态。 例如：rise:不及物动词 raise:及物动词 the price has been risen. (falt) the price has risen. (true) the price has raised. ( falt) the price has been raised. (true)
be+pp:I wrote the sentence.-->The sentence was written by me.
do →be +done
I gave him the book→The book was given to him.
→He was given the book.
be+动词过去分词I was hit. I was asked a question by you. The window was broken yestday evening
be+动词过去分词;The window was broken yestday evening.
被动语态的关键是助动词be,没有它就不是被动语态。
比如：I was asked a question by you.
