  ① 一般式(一般现在,一般过去,一般将来):am, is, are, was, were, is going to be , will be+done.ie. Once environmental damage is done, it takes many years for the system to recover. 本句的意思是:“环境一旦遭到破坏,需要多年时间才能恢复过来。”do作为及物动词有“引起,产生”的含义,do damage的意思是“造成破坏”。主语damage是及物动词do的动作对象,谓语应当用被动语态。同样的,还有,I will mend the machine.相当于The machine will be mended (by me).

  ② 进行时(现在进行、过去进行、将来进行):be+being+P.P. ie.The classroom is being cleaned.

  ③ 完成时(现在完成、过去完成、将来完成):have/has been + P.P.:例如The machine will have been repaired by 3 o’clock this afternoon.再如:My homework has been finished.

  ④ 其他时态依词类推,可得到结果。

  ⑤ 情态动词的被动语态:主语 + 情态动词 + be动词 + 动词过去分词,例如Your teeth must be brushed.

  ⑥ 不定式的被动语态:to be done例:The no-shows have to be considered when deciding the rate of overbooking.(确定超过接待能力的预定时必须考虑预定了房间却来不了的客人。)


  ① 有些动词在主动结构中,后面接不带to的不定式,但如果改为被动,则需把省略的to加上,这类动词有hear, watch, make, help, let等,如:The boss made my grandfather work 10hours a day.改成My grandfather was made to work for 10 hours a day.

  ② 含有宾语从句的主动结构变为被动,通常用it作为被动结构的先行主语,从句放在句子后面/也可采用另一种形式,这类动词有:know, say, believe, find, think, report等

  ③ 是所有的主动句都可以变换成被动句,更不是所有的被动句都可以自由变换成主动句。虽然语法原则上允许主动和被动句的互相转换,但有的句子转换后会变成不通顺或不地道的英语句子。因此,在某些题目里,这也成为判断应该用主动还是用被动的依据。

  例:At 5:05 p.m. on Saturday 19th July , there was an accident at the junction of the Main Street and Panda Road when a boy was knocked down off his bicycle by a delivery van. The boy was sent to St. Maria Hospital where he was treated for shock and a broken arm.

  在这段文章里,a boy was knocked down off his bicycle by a delivery van这句被动句强调出读到文章的人最关心的事故的受害者。The boy was sent to St. Maria Hospital这句话则说明了孩子被送到医院的事实,至于是由谁(某个过路人?或肇事司机?)送的不重要。he was treated for shock and a broken arm这句被动句无须说出treat这个动作的发出者,因为在医院,伤病员自然由医务人员处理,无须罗嗦。这样,这段文章就重点突出,条理清楚了。

  ④ 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,另一个宾语仍然保留在谓语后面。多是把间接宾语变为主语。这样句子自然些。直接宾语变为主语时,间接宾语要变为某个介词的宾语,介词to可以省略。如His father left him this house.改为This house was left (to) him by his father.

  ⑤ 有些动词虽为及物,但宾语并非是动作承受者,不能转换,这些动词有have, hold(容纳),suit, fit, lack, become(适合)contain, cost, last, mean, suffice(足够)等。

  ⑥ 当直接宾语为反身代词、相互代词或宾语前有指代主语的物主代词时不用被动,如I shook my head.我摇摇头。

  ⑦ 当宾语为同源宾语(与主句指同一人),动名词,动词不定式或一个从句时不用被动。如John enjoyed seeing the fil,.

  ⑧ 在一些固定说法中,有些名词和动词结合的固定说法,不能改We Chinese always keep our word.

  ⑨ 某些从不及物动词转化来的及物动词,直接宾语在表示动作的方式或效果时,这些动词在意思上起状语的作用,没有被动The girl kissed her boyfriend good night=The girl said good night to her boyfriend by kissing him.

  ⑩ 表地点\处所\组织\长度\大小\数量\程度\抽象名词的词做宾语时不用被动.

  ⑪ 某些“不及物动词+介词”短语,walk into, listen to, sleep in, agree with, shake hands with, belong to, take part in, keep up with不能用被动。

  ⑫ 某些词用主动表被动:sell, miss, build, grow, look, smell, taste, sound, feel等
