请同学们观察以下句子并找出其中的一般过去时的被动语态。
① When was the zipper invented
② Who was it invented for
③ It was invented by Whitcomb Judson.
④ It’s used for serving really cold ice-cream.
【知识讲解】
1、基本构成：_________ + done
2、句式：
（1）一般疑问句：_________ + 主语 + done + 其他？
（2）特殊疑问句：_________ + was/were + 主语 + done + 其他？
（3）肯定句: 主语 + was/were + done + 其他。
（4）否定句: 主语+ was/were + not + done+ 其他。
3、注意：
（1）不及物动词无被动语态。
·What will happen in 100 years
100年后将会发生什么事
（2）有些动词用主动形式表示被动意义。
·This pen writes well. 这支钢笔好用。
·This new book sells well. 这本新书很畅销。
（3）感官动词或使役动词使用省略to的动词不定式, 主动语态中不带to, 但变为被动语态时, 必须加上to。
·My mother makes me do housework every day.
=I am made to do housework by my mother every day.
妈妈每天让我干家务。
·I saw them play basketball yesterday.
=They were seen to play basketball by me yesterday.
昨天我看见他们打篮球了。
（4）如果是接双宾语的动词改为被动语态时, 直接宾语(物)作主语, 那么动词后要用介词, 这个介词是由与其搭配的动词决定的。
·He gave me a book. →A book was given to me by him. 他给了我一本书。
·He showed me a ticket. →A ticket was shown to me by him. 他给我看了一张票。
·My father bought me a new bike. →A new bike was bought for me by my father. 爸爸为我买了一辆新自行车。
（5）一些动词短语用于被动语态时, 动词短语应当被看作一个整体, 而不能丢掉其中的介词或副词。
·He listens to the radio every day. →The radio is listened to by him every day. 他每天听收音机。
·The nurse is taking care of the sick man. →The sick man is being taken care of by the nurse. 那个护士正在照顾病人。
