一般过去时的被动语态
命题情报
一般过去时的被动语态是历年中考重点考查的语法项目之一，考纲要求学生了解并掌握一般过去时被动语态的肯定句、否定句以及一般疑问句的结构，能从主动语态变为被动语态。该考点大多出现在单项选择、词汇或完成句子等题型中。同时在阅读理解、完形填空的选材中也都有所体现，不少文段中都含有一般过去时的被动语态。
The tea was invented by Shen Nong.
一般过去时
的被动语态
be+及物动词的过去分词(被动语态结构)
概念 主语是动作的承受者，且动作发生在过去，就用一般过去时的被动语态。
结构　was/were+及物动词的过去分词
1 被动语态的用法
用法 例句
不知道或没必要指出动作的执行者 These books were written for
children.这些书是为儿童写的。
强调或突出动作的承受者 The book was written by Mo Yan.
这本书是由莫言写的。
用法 例句
动作的执行者不是人而是无生命的事物 Many traffic accidents were caused by careless driving.很多交通事故是由粗心驾驶造成的。
为了表示委婉或礼 貌，避免提及动作执行者或说话者自己 He was asked to give a talk about how to learn English well. 他被要求做关于怎样学好英语的报告。
2 主动语态和被动语态的相互转化
主动句： 动作的执行者(主语)+谓语动词+动作
的承受者(宾语)
被动句： 动作的承受者(主语)+be+及物动词的过
去分词 + by + 动作的执行者
[巧记] 宾语提前主语变， 原主变宾by后见，时态人称be关键。
[注意] 把主动语态变为被动语态时，其谓语动词的时态要与主动句的时态保持一致，其谓语动词要与被动句的主语在数上保持一致。
拓展 含有双宾语的主动句变被动句
1. 若指“人”的间接宾语变为主语，指“物”的直接宾语保持不变。
2. 若指“物”的直接宾语变为主语，则在间接宾语前加to或for。如：
She gave me a book yesterday. (主动语态)
→I was given a book by her yesterday. (被动语态)
A book was given to me by her yesterday. (被动语态)
考点直击
Ⅰ. 单项选择
1. |重庆中考| Another bridge over the Jialing River________ last year.
A. builds B. built
C. is built D. was built
D
[解析]考查动词时态和被动语态。本句主语Another bridge与动词build之间是被动关系，因此此处应用被动语态。再根据表过去的时间状语last year可判断，应用一般过去时态的被动语态。故选D。
2. |安顺中考| — Wow! You have a ticket to the Expo!
— It _________by my uncle. He is working in Shanghai.
A. has bought B. had bought
C. is bought D. was bought
D
3. |襄阳中考|—Why have I never seen this kind of 5G
mobile phone
—Because it _________by Huawei last week.
A. was produced B. would produce
C. have produced D. was producing
A
[解析]考查动词的时态和语态。句意：“为什么我从来没有见过这种5G手机？”“因为它是上周由华为生产的。”根据时间状语“last week”可知，谓语动词用一般过去时。又因it与produce之间存在被动关系，故用被动语态。故选A。
4. |北京中考| The kite ________in China more than 2,000
years ago.
A. invents B. invented
C. is invented D. was invented
D
5. |天津中考| Paper ________first ________ about 2,000 years ago in China.
A. is; creating B. is; created
C. has; created D. was; created
[解析]考查动词的时态和语态。paper与create之间是被动关系，故用被动语态，再由时间状语“about 2,000 years ago”可知，用一般过去时。故选D。
D
Ⅱ. 将下列句子改为被动语态
1. My students always shared ideas in class last year.
Ideas ________ always _________ by my students in class
last year.
were shared
2. They rebuilt the earthquake areas five years ago.
The earthquake areas _________ _________ by them five years ago.
3. Lily didn’t invite me to the party.

At night I had a dream. I dreamed that I went to visit the Grand Canyon. When I got out of the car, the skywas becoming light.
After about forty minutes I stood on the edge of the Grand Canyon. The sun rose behind me.Suddenly a piece of music came to my ears. I listened carefully, but it disappeared in the distance. I looked across to the other side of the canyon. Oh, it was my favorite band performing over there! I was so excited. Just then I woke up.What an interesting dream!
