  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)

   [即时演练3] 

  (1)句型转换(每空一词)

  ①I didn't notice her enter the office.

  →She wasn't noticed to enter the office.

  ②Someone saw a stranger walk into the building.

  (2)Last December, 14 bears were seen ________ from the bile (胆汁) trade in Vietnam.

  A.rescued B.to rescue

  C.rescuing D.rescue

  解析:选A "see sb./sth. do/doing/done"为常用结构,这一结构的被动语态为"be seen to do/doing/done"。分析题干可知,空格处与句子的主语之间为动宾关系,所以应用过去分词"rescued"。故选A。

   (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.

  据说一个新的火车站将在我的家乡建起来。

  The baby is being taken care of by his grandmother.

  这个婴儿正由他祖母照顾。
