2、用done表示）”构成，be随着主语人称和数以及时态的不同而变化。The TV is made of plastic.It was made in Chongqing.A sports meeting will be had in October.Teenagers should be allowed to make their own decision.An evening party is being having now.My homework has already been done.,常见的4种形式的被动结构如下：1、一般现在时的被动语态：am/is/are + V-edThe f

4、y / should + be + V-ed”构成。Sixteen-year-olds should not be allowed to drive.,三、 主动语态变被动语态的方法（1）图示：主动句：They clean the classroom. 主语 谓语 宾语 被动句：The classroom is cleaned by them. 宾语变主语 be+过去分词 主语变宾语由by引出,(2) 口诀：宾变主，主变宾，谓语动词用被动。(3) 变换步骤： 将主动句的宾语变为主语。 注意：如果主动句的宾语是代词，需将其由宾格变为主格。如： This village is so beautif

5、ul that many visitors visit it every year.This village is so beautiful that it is visited by many visitors every year. 这个村庄很美，以至于每年有很多人来参观它。,将动词改为“be+过去分词”。 注意：be动词与新主语相一致，时态不变。如： They held a meeting yesterdayA meeting was held by them yesterday他们昨天开会了。将主动语态的主语改为by.，放在谓语动词后。 注意：如果原主语是代词，则应由主格变为宾格。如：

9、ught for,were given to,was,given,2、“不及物动词+介词/副词”结构的短语动词相当于及物动词，可以有被动语态。但短语动词是一个不可分割的整体，在变为被动语态时，不可丢掉构成短语动词的介词或副词。如：They took good care of the poor kids. The poor kids were taken good care of by them. (of不可省略)Practice:We should speak to old men politely.We cant laugh at him.,Old man should be spoken

10、to (by us),He cant laughed at (by us),3、若宾语和后面的宾语补足语一起构成复合宾语，变为被动语态时，只将宾语变为被动句的主语，宾语补足语保留在原处，成为主语补足语。如：They encouraged us to study hard every day.We were encouraged to study hard every day. (to study hard every day为主语补足语)Practice:His mother often tells him not to play in the street.He _often _not to

11、 play in the street by his mother.,is,told,4、在主动句中，感官动词see , hear, watch, feel, notice等和使役动词let, make等后接省略to的不定式，变为被动语态时，应加上动词不定式符号to。如：We heard them sing Peking Opera in the theater.They were heard to sing Peking Opera in the theater.They make her clean the floor.

19、y.,sells,washes,7、主动形式表示被动：sth. need/ want/ require doing相当于sth. need/ want/ require to be done(不定式的被动结构)。例如: Your room needs cleaning. = Your room needs to be cleaned. 你的房间需要打扫了。我的车需要修理。My car needs repairing. =My car needs to be repaired. Practice:My desk is broken.It needs_ (repair)be worth doing

20、(值得做)中的doing表示被动含义。例如:The movie is worth watching by everyone. 这部电影值得所有人看一看。,repairing=to be repaired,六、被动语态与系表结构的区别“be + p. p. ”表示动作时是被动语态; “be + p. p. ”表示主语所处的状态时是系表结构。(1)含有“by +宾语”结构强调动作执行者, 此时为被动语态。例如: The window is broken. 窗户坏了。(系表结构)The window is broken by me. 窗户是我打破的。(被动语态)(2)句中有地点、频率或时间状语时,

22、introduced into Europe from China.印刷术是由中国传入欧洲的。2、没必要指出动作的执行者。He was born in 1980.他出生于1980年。3、需要强调突出动作的承受者。She is liked by everyone here.她被这儿所有人喜欢。4、动作的发出者不是人。My dog was washed away by the flood.我的小狗被洪水冲走了。,Step 3 Practice1.
