初三英语讲解 被动语态

初三讲解(三)
被动语态
一、被动语态的时态及结构（以动词do为例）
1. 结构：主语 + be + 过去分词
(过去分词不变，所有人称，数，时态的变化，都体现在助动词be的变化上。)
2. 时态： (前三种形式为四会掌握内容)
1. 一般现在时： am (is, are) done.
2. 一般现在时带情态动词的被动语态：must (can, may) be done
3. 一般过去时： was (were) done
* 4. 一般将来时： will (shall) be done
* 5. 现在进行时： am (is, are) being done
* 6. 现在完成时： have (has) been done
e.g. (1) History is made by the people. 历史是人民创造的。
（主语是第三人称单数，用is， by 后面加动作的执行者）
(2) These new cars were made in Tianjin in 1994.这些新车是1994年在天津生产的。
（主语是第三人称复数，时态为一般过去时，因此用were）
(3) Li Ming will be asked to attend the lecture. /Li Ming is going to be asked to attend the lecture. 李明将被邀请参加讲座。 （一般将来时的被动语态，用will be）
(4) A new railway is being built. 一条新铁路正在修建。
(主语是第三人称单数，现在进行时的被动语态， 用is being)
二. 被动语态的否定及疑问
e.g. The students clean the classroom everyday. (主动句)
The classroom is cleaned (by the students) every day. （被动句）
The classroom isn’t cleaned every day. （被动语态的否定句）
Is the classroom cleaned every day? Yes, it is.（被动语态的一般疑问句）

Unit 3 Teenagers should be allowed to choose their own clothes.

get in the way 妨碍 worry about 为……担心（焦虑）

重点句子

语法:
被动语态（Be + done）
英语中有主动和被动两种语态。前者以动作的执行者充当主语，后者以动作的承受者 (即宾语) 充当主语。由于只有及物动词才有宾语，因此只能是及物动词才有被动语态形式。
被动语态以助动词be加上动词的过去分词构成，如：
We speak English. (主动语态) English is spoken. (被动语态)
有时为了表明动作的执行者，可在被动语态句型中加上介词by引导的短语，如：
The glass was broken by the cat yesterday.
由于动词be在不同时态中有不同形式，因此被动语态在各种时态中也有不同的结构。一般现在时由am/are/is加上过去分词构成，如：
Football is played all over the world. The rooms are cleaned every day.
被动语态：句子的主语是谓语动词的动作的承受者或者主语是动作的对象，因此只有及物动词才有被动语态。如：
English is spoken by many people in the world.
世界上的许多人讲英语（英语由世界上的许多人讲）。
句中的English就是动词speak的承受者。当要强调动作执行者的时候，用介词by加上这个动作的执行者来表示就可以了，如句中的by many people结构。
被动语态的构成： be + done （动词过去分词），各种时态由be 表示，如：
Our classroom is cleaned every day, but it wasn't cleaned yesterday. It will be cleaned by Group1 tomorrow. 我们的教室每天都打扫，但昨天没扫，明天由第一组清扫。
文中的被动语态是由情态动词should + be +done 组成。

我认为应该允许青少年每天晚上和朋友们出去。
2. I don’t think fifteen-year-olds should be allowed to get their ear pierced.
我认为不应该允许十五岁的孩子扎耳眼儿。

How did the classroom get so dirty?
教室怎么搞得这么脏？
He often gets the answers wrong.
他经常把答案弄错。

A bag is useful and the word “bag” is useful, too. It gives us some interesting phrases (短语). One is “to let the cat out of the bag”. It is the same as “to tell a secret”. There is an old interesting story about it. Long long ago when people sold things in big cloth bags, a woman asked a man for a pig. The man helped up his cloth bag. There seemed to be a little pig in it. The woman asked to see it. When the man opened the cloth bag, a big black cat ran out. Not a pig! The man’s secret was out and everyone knew it.
Now when someone lets out a secret, he “let the cat out of the bag”. And that is the story of where the interesting phrase came from.

He always sets a good example himself so as to influence his pupils.
