专题09 被动语态
【学习目标】
1、通过理论依据,能理解被动语态的构成;
2、通过背诵该语法,能正确分析被动语态在语境中的应用;
3、通过大量训练,能在篇章填空和写作中正确应用。
【探究活动】动词的语态
语态有两种:主动语态和被动语态。
主语是动作的发出者为主动语态;主语是动作的接受者为被动语态。如:
They will build a new bridge over the river. (主动) A new bridge will be built over the river. (被动)
汉语中常用“被”、“给”、“由”、“受”等词用来表示被动,而英语用:助动词be+ 及物动词的过去分词构成。
被动语态的构成及用法
一、通过例句总结被动语态的构成形式
1. Rice is grown in the south of the states.
2. We are not allowed to enter the chemistry lab without a teacher.
3. The task was finished on time.
4. All the books were sent to the remote regions.
5. Plenty of jobs will be given to school-leavers.
6. The workers told me that the car would be mended as soon as possible.
7. I have been told the sports meet might be put off.
8. The price has been brought down.
9. When I got to the theatre, I found the tickets had already been sold out.
10. The rooms are being painted.
11. Trees were being planted here this time last year.
12. A great many letters can be written with the computer by him.
总结:被动语态最基本的句型结构是: _________________________________
一般现在时:_________________________________
一般过去时: _________________________________
一般将来时: _________________________________
过去将来时: _________________________________
现在完成时: _________________________________
过去完成时: _________________________________
现在进行时:_________________________________
过去进行时: _________________________________
含有情态动词的被动语态: _________________________________
二、被动语态的常见考点
1.被动语态中的谓语动词一定要是及物动词
因为被动句中的主语是动作的承受者,某些短语动词如look after, think of, take care of, work out, laugh at等,也可用于被动语态。如:The children were taken good care of by her.
【注意】短语动词中的介词或副词变成被动语态时不可遗漏。
表示“发生、进行”的不及物动词和短语,如:happen, last, take place, break out, come out, come about, come true, run out, give out, turn out等无被动语态。
如:1) A car accident happened in the street yesterday.
2) Great changes have taken place in China in the past five years.
2.主动语态变为被动语态要加“to”的情况
若宾语补足语是不带to 的不定式,变为被动语态时,该不定式前要加“to”。如:feel, hear, help, listen to, look at, make, observe, see, notice, watch等。
如:
