2、s (by us).( am/is/are +done (过去分词) 一般现在时被动语态)2.The boss gave me ten minutes to decide whether i should reject the offer.

4、in.(be about to be done) I am to buy a car in the coming month.(be to do) A car _ by me in the coming month.(be to be done) (will/shall/be going to/be about to/be to +be done)一般将来时被动语态引申:People would/should/ were going to/were about to/were to send the news to soldiers mother as soon as it arrived.
5、The news _ the soldiers mother as soon as it arrived.4.We have completed all the preparation for the task. (have done) All the preparations for the task _ by us.(have been done) (have been done)现在完成时被动语态5. By the end of last year, Beijing had completed another new gym.(had done) By the end of last y

(will have been done)将来完成时被动语态7. The city is building a new cinema here.(be doing) A new cinema _ here by t
7、he city.(be being done) (be being done)现在进行时被动语态8.They were holding a meeting when I was there.(be doing) A meeting _ when I was there.(be being done) (be being done)过去进行时被动语态三. 被动语态的特殊结构形式1)带情态动词的被动结构。其形式为:情态动词be过去分词。The baby-sitter should take good care of the baby.The baby _by the baby-sitter.2)有
8、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 _by his mother for his birthday.3) 当“动词+宾语+宾语补足语”结构变为被动语态时,将宾语变为被动结构中的主语,其余不动。Someone caught the boy smoking a cigarette. The boy _a cigarette.4)在使役动词have, make, get以及感官动词see, watch,
9、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。Someone saw a stranger walk into the building. A stranger _ into the building.5) 有些相当于及物动词的动词词组,如“动词介词”,“动词副词”等,也可以用于被动结构,但要把它们看作一个整体,不能分开。其中的介词或副词也不能省略。We put off the meeting till Friday.The meeting _ till Friday.四、 It is said tha
10、t+从句及其他类似句型一些表示“据说”或“相信”的动词如believe, consider, expect, report, say, suppose, think等可以用于句型“Itbedonethat从句”或“主语bedoneto do sth.”。有:It is said that/It is said to do 据说,It is reported that/It is reported to do据报道,It is believed that/It is believed to do大家相信,It is hoped that/It is hoped to do大家希望,It is w
11、ell known that/It is well known to do众所周知,It is thought that/It is thought to do大家认为,It is suggested that/It is suggested to do据建议。It is said that the boy has passed the national exam. (The boy is said to have passed the national exam. )五、谓语动词的主动形式表示被动意义1.英语中有很多动词如 break,catch,clean,drive,lock,open,
12、sell,read,write,wash等,当它们被用作不及物动词来描述主语特征时,常用其主动形式 表达被动意义,主语通常是物。This kind of cloth washes well.The door wont lock (指门本身有毛病)The door wont be locked (指不会有人来锁门, 指“门没有锁”是人的原因)2. 系动词没有被动形式, 但有些表示感受、感官的连系动词feel, sound, taste, book, feel等在主系表结构中常以主动形式。Your reason sounds reasonable.六、非谓语动词的主动形式表被动意义1 在need,
13、want,require, bear等词的后面,动名词用主动形式表示被动意义,其含义相当于动词不定式的被动形式。The house needs repairing(to be repaired)这房子需要修理。2形容词worth后面跟动名词的主动形式表示被动含义,但不能跟动词不定式;The picture-book is well worth reading3. I have a lot of things to do this afternoon 4. 形容词不定式的主动形式表达被动意义。这些形容词有nice,easy,fit,hard,difficult,important,impossi
14、ble,pleasant,interesting等。例This problem is difficult/easy/hard/important/impossible/interesting to work out .七、被动语态与系表结构的区别当“be+过去分词”作被动语态时表示主语承受的动作;作系表结构时表示主语的特点或所处的状态时,be后面的过去分词是表语,相当于形容词。其区分办法如下:The glass is broken (系表结构)The glass was broken by the boy (被动语态)七、被动语态与高考试题赏析1).
