例：Make somebody do something →somebody+ be +made to do something See somebody do something →somebody +be +seen to do something

4. 如果是接双宾语的动词改为被动语态时，直接宾语（物）做主语，那么动词后要用介词，这个介词是由与其搭配的动词决定。

He showed me a ticket. →A ticket was shown to me by him. 他给我展示了一张票。 My father bought me a new bike. →A new bike was bought for me by my father. 我父亲给我买了一辆新自行车。
5. 一些动词短语用于被动语态时，动词短语应当看作一个整体，而不能丢掉其中的介词或副词。
