来源:丹东城市网 | 2008/1/24 20:19:38
 1)带情态动词的被动结构。其形式为:情态动词+be+过去分词。

  【例如】

  The baby should be taken good care of by the baby-sitter. This instrument must be handled with great care. In this sense, bad things can be turnedsintosgood things.

  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。

  【例如】

  The delegation was given a warm send-off at the airport. He was asked a number of questions at the press conference. Two days were allowed them for making the necessary preparation.

  3)当“动词+宾语+宾语补语”结构变为被动语态时,原句中的宾语补语成为主语补语。能用这种结构的动词有:declare, call, consider, elect, appoint, nominate, find, leave, like, make, prefer, think, want等。

  【例如】

  She was nominated a member of the council. Professor Smith was appointed the head of the Philosophy Department.

  4)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to.

  【例如】

  A stranger was seen to walksintosthe building. She was made to clean the floor.

  5)某些感官动词加形容词可以表示被动意义。

  【例如】

  The dish tastes delicious.The apple smells sweet.

  6)It+be+过去分词+that从句,或主语+be+过去分词+to do sth.

  【例如】

  It is said that the boy has passed the national exam. The boy is said to have passed the national exam. It was reported that 60% students in the university had passed CET-6.60% students in the university were reported to have passed CET-6.
