　　三、被动语态的特殊结构形式

　　1．情态动词(may，might，can，could，should，ought to，must)＋be＋过去分词，构成被动语态。

　　Nowadays，solar energy can be used to produce electricity in many countries.

　　现在太阳能在许多国家可以被用来发电。

　　A real sense of achievement and happiness may be felt.一种真正的成就感和幸福感可以被感觉到。

　　The pollution must be stopped.

　　必须停止污染。

　　2．使役动词和感官动词的被动语态

　　(1)在使役动词have，make，get以及感官动词see，watch，notice，hear，feel，observe等后面不定式作宾语补足语时，在主动结构中不定式to要省略，但变为被动结构时，要加上to。get，leave，cause等使役动词的宾语补足语是带to的不定式，变为被动语态时该不定式不变。

　　My father made me stay up late to finish my homework.(表示主动)

　　I was made to stay up late to finish my homework by my father.(表示被动)

　　(2)有些动词可以有两个宾语，在用于被动结构时，可以把主动结构中的一个宾语变为主语，另一宾语仍然保留在谓语后面。通常变为主语的是间接宾语。

　　His mother gave him a present for his birthday.

　　→He was given a present by his mother for his birthday.他妈妈送给他一份生日礼物。

　　3．短语动词的被动语态

　　短语动词是一个整体，不可丢掉它后面搭配的介词或副词。

It is said that a new railway station will be set up in my hometown.
