英语被动语态定义9种结构对应的9个例句

贺仁栋回答:
  1被动语态的构成   被动语态的基本结构是“助动词be+过去分词”.被动语态的谓语动词有各种时态变化,以动词take为例,将被动语态常见时态的动词形式列表如下:   一般现在时   现在进行时   现在完成时   一般将来时   am/is/are   taken   am/is/are   beingtaken   have/hasbeen   taken   will/shallbe   taken   一般过去时   过去进行时   过去完成时   过去将来时   was/were   taken   was/were   beingtaken   hadbeen   taken   would/should   betaken   从上表中可以看出,被动语态的各种时态变化都是通过助动词“be”的各种时态来表示的,因此只要知道“be”的时态形式,也就掌握了被动语态构成   2被动语态的基本时态变化   被动语态通常为十种时态的被动形式,被动语态由be+过去分词构成,be随时态的变化而变化.以do为例,各种时态的被动语态形式为:   1)am/is/are+done(过去分词)一般现在时   例Visitorsarerequestednottotouchtheexhibits.   2)has/havebeendone现在完成时   例Allthepreparationsforthetaskhavebeencompleted,andwe'rereadytostart.   3)am/is/arebeingdone现在进行时   例Anewcinemaisbeingbuilthere.   4)was/weredone一般过去时   例IwasgiventenminutestodecidewhetherIshouldrejecttheoffer.   5)hadbeendone过去完成时   例Bytheendoflastyear,anothernewgymnasiumhadbeencompletedinBeijing.   6)was/werebeingdone过去进行时   例AmeetingwasbeingheldwhenIwasthere.   7)shall/willbedone/begoingtobedone/beabouttobedone/betobetodone一般将来时   例Hundredsofjobswillbelostifthefactorycloses.   8)should/wouldbedone/wasweregoingtobedone/waswereabouttobedone/wasweretobetodone一般将来时   例Thenewswouldbesenttothesoldier'smotherassoonasitarrived.   9)shall/willhavebeendone将来完成时(少用)   例TheprojectwillhavebeencompletedbeforeJuly.   10)should/wouldhavebeendone过去将来完成时(少用)   例Hetoldmethathisnewclotheswouldhavebeenmadeverysoon.
