Summary
被动语态的用法：
1.定义：即不知道动作的执行者或强调动作的承受者的一种语态。
2.谓语动词的构成： be+dne(过去分词) (+by+动作执行者)
3.主动语态：S. + v. +O.

被动语态：O.+be+v.-ed +by S.
被动语态的用法：
不知道动作的执行者是谁。e.g. This watch is made in China.
没有必要指出动作的执行者是谁。e.g. Mre trees must be planted.
需要强调或突出动作的承受者。e.g. Chinese is spken by mre and mre peple in the wrld.
句子的主语是动作的承受者。 e.g. Many huses were washed away in the fld.
5.被动语态的各种时态变化：即be的变化e.g. He writes a bk.
一般现在时：am/is/are dne
e.g. A bk is written by him .
一般过去时：was/were dne
e.g. A bk was written by him last mnth.
一般将来时：will be dne
e.g. A bk will be written by him next week.
过去将来时：wuld be dne
e.g. He said a bk wuld be written by him.
现在进行时：am/is/are being dne
e.g. A bk is being written by him nw.
过去进行时：was/were being dne
e.g. He said a bk was being written by him.
现在完成时：have/has been dne
e.g. A bk has been written by him.
过去完成时：had been dne
e.g. A bk had been written by him by the end f last mnth.
6.含有情态动词的被动语态：
Can/may/must be dne
e.g. A bk must be written by him nw.
带双宾语的谓语动词变被动语态：可以将间接宾语转化为主语，则保留直接宾语；若将直接宾语转化为主语则保留间接宾语，且在被保留的间接宾语前加上介词t或fr.
E.g. She gave me a bk.
I was given a bk.
A bk was given t me.
主动语态中省略的t变被动语态时要加上。
主动语态中在感官动词see, hear, watch, feel, ntice等和使役动词let, make, have等后省略的t,变被动语态时要加上。
e.g. He makes the girl stay at hme.——The girl is made t stay at hme.
We heard him sing in the next rm.——He was heard t sng in the next rm.
不及物动词happen, take place等没有被动语态形式。
e.g. The cntest will take place next week.
read, write, sell, wash, clean等词用主动表被动意义。
e.g. The pen writes well. 这支笔写起来很好。
need ding=need t be dne "需要做某事",用主动表被动意义.
e.g. The bike needs repairing.=The bike needs t be repaired.
be wrth ding "值得做某事", 用主动表被动意义。e.g. The bk is wrth reading.
