初二英语下册语法复习(人教版)- 被动语态(一)

一、被动语态概述

语态是动词的一种形式,用以说明主语与谓语动词之间的关系。英语的语态共有两种:主动语态和被动语态。主动语态表示主语是动作的执行者,被动语态表示主语是动作的承受者。被动语态是动词的一种特殊形式,一般说来,只有需要动作对象的及物动词才有被动语态。汉语往往用"被"、"受"、"给"等词来表示被动意义。

如:

He opened the door.他打开了这扇门。(主动语态)

The door was opened.这扇门被打开了。(被动语态)

二、被动语态的构成

被动语态由"助动词be+及物动词的过去分词"构成。被动语态的时态变化只改变be的形式,过去分词部分不变。疑问式和否定式的变化也如此。

1、被动语态的时态较常见的八种,现以动词clean为例列表说明:

2、被动语态的句式变化:

以一般现在时和动词invite为例,列表说明被动语态的句式变化:

3、含有情态动词的被动语态

情态动词的被动语态结构为:情态动词+be+过去分词;其时态及句型的变化仅由情态动词完成,"be+过去分词"部分不变。如:

Tables can be made of stone.桌子可由石头制造。

Tables could be made of stone at that time. 那时桌子可由石头制造。(一般过去时) Can tables be made of stone? 桌子能用石头制造吗?(疑问句)

三、主动语态变为被动语态

转换图示:

1、主动语态变为被动语态的步骤:

(1)将主动句的宾语变为主语:

注意:如果主动句的宾语是代词,需将其由宾格变为主格。如:

Tom killed him. → He was killed by Tom.

(2)将动词改为"be+过去分词"。

注意:They held a meeting yesterday. → A meeting was held by them yesterday.他们昨天开会了。

(3)将主动语态的主语改为be…放在谓语动词后。

注意:如果原主语是代词,则应由主格变为宾格。

He sang a song. → A song was sung by him.

2、主动语态变为被动语态的注意事项:

含有双宾语,即直接宾语(常指事物)和间接宾语(常指人)的句子,每个宾语都可变为被动语态的主语,即其被动语态有两种形式。但多以间接宾语作主语。

Jack told us the truth.杰克告诉了我们真相。

We were told the truth by Jack.

The truth was told (to) us by Jack.

四、动词的主动形式表示被动之意

系动词无被动语态:以主动形式表示被动之意

常见的系动词有:

① be动词

② ……起来(7个):look/seem/appear, feel(感觉,摸起来), sound, smell, taste e.g. She seems/appears happy. It smells terrible.

③ (逐渐)变得/变成:become, grow, get, turn, come, go

e.g. His wish has come true.

People often went hungry in the old days.

The tree is growing tall.

④ 保持:keep, stay

e.g. We must keep quiet in the reading room.

五、下列动词(词组)没有被动式:

1、happen, take place, break out, belong to ,cost, take

2、不及物动词sell, wash, read , write, open, close, shut, lock, wear等,常用主动形式表示被动意义。

○1、An accident was happened yesterday.(×)昨天发生了一起事故。

An accident happened yesterday.

○2、The flower smells sweet.这花闻起来很香。

○3、The watch looks good.这表看起来很好。

○4、This book sells well.这本书畅销。

○5、The kind of cloth washes well. 这种布很容易洗。

○6、The article reads well. 这篇文章读起来很好。

○7、The supermarket opens at 8:00 in the morning. 超市在早上八点钟营业。

○8、The door won't close/shut. 这门关不上。

○9、The door locks easily. 这门容易锁。

○10、This material wears well (won't wear). 这种材料耐久(不耐久)

六、各种时态的被动语态举例(以动词do为例)

1.一般现在时(am/ is/ are +done)

English is spoken by lots of people in the world. 世界上的许多人都说英语。

Class meeting is held every Thursday. 每周四都举行班会。

The classroom is cleaned by the students every day. 学生们每天都打扫教室。

2.一般过去时(was/ were +done)

The cup was broken by the boy. 杯子被那个男孩打碎了。

He was saved at last. 他最终获救了。

My bike was stolen. 我的自行车被偷了。

3.一般将来时与过去将来时(will/ shall be +done; would/should be +done)

A speech will be given this afternoon. 今天下午有一个演讲。

A new road will be built next year. 明年要修一条新马路。

I thought thousands of people would be helped. 我认为将有数千人得到帮助。

4.现在进行时与过去进行时(am/ is/ are being +done; was/ were being +done)

The machine was being repaired at this time yesterday. 昨天这时,机器正在被修理。 The problem is being discussed now. 问题正在被讨论。

A bus is being pushed by the passengers. 路人正在推一辆公共汽车。

5.现在完成时(have/ has been + done)

Two hundred trees have been planted by now. 到现在为止,已经种了二百棵树了。 The book has been read many times by me. 这本书已经被我读了许多遍了。

6.过去完成时(had been+done)

They said they had been invited to the party. 他们说已经被邀请参加晚会了。

She found the house had been destroyed by the storm. 她发现房子已经被暴风雨摧毁。

He had been tortured by the illness for many years before he died.他在去世前已经被疾病折磨很多年了。

21) stop to do sth 与 stop doing sth

1. stop to do sth 意为"停下来去做某事"。如:

The students stop to listen to their teacher.

学生们停下来去听他们老师讲话。

2. stop doing sth 意为"停止做某事"。如:

The students stopped talking. 学生们停止了谈话。

与它们相反的句式是:go on to do sth "继续做某事(与刚才一事不同)"

和 go on doing sth "继续做某事(与刚才同一件事)"。如:

He finishes his homework and goes on to study English.

他完成了作业,接着继续去念英语。

They went on playing games. 他们继续玩游戏。

forget doing/to do与remember doing/to do

1.forget to do忘记要去做某事(未做);forget doing忘记做过某事(已做)

The light in the office is still on. He forgot to turn it off.

办公室的灯还在亮着,它忘记关了。(没有做关灯的动作)

He forgot turning the light off.

他忘记他已经关了灯了。( 已做过关灯的动作)

Don't forget to come tomorrow.

别忘了明天来。(to come动作未做)

典型例题

---- The light in the office is still on.

---- Oh,I forgot___.

A. turning it off B. turn it off

C. to turn it off D. having turned it off

答案:C。由the light is still on 可知灯亮着,即关灯的动作没有发生,

因此用forget to do sth.而forget doing sth 表示灯已经关上了,而

自己忘记了这一事实。此处不符合题意。

2.remember to do记得去做某事(未做);

remember doing记得做过某事(已做)

Remember to go to the post office after school.

记着放学后去趟邮局。

Don't you remember seeing the man before?

你不记得以前见过那个人吗?

8) It's for sb.和 It's of sb.

1.for sb. 常用于表示事物的特征特点,表示客观形式的形容词,如:

easy, hard,difficult,interesting,impossible等:

It's very hard for him to study two languages.

对他来说学两门外语是很难的。

2.of sb的句型一般用表示人物的性格,品德,表示主观感情或态度的形容词, 如:good, kind, nice, clever, foolish, right。

It's very nice of you to help me. 你来帮助我,你真是太好了。

3.for 与of 的辨别方法:

用介词后面的代词作主语,用介词前边的形容词作表语,造个句子。如果道理上通顺用of,不通则用for。如:

You are nice. (通顺,所以应用of)。

He is hard. (人是困难的,不通,因此应用for。)

25) Other及其用法

Other 及其相近的词(组),如 others, the other, the others, another,

any other 等,一直是中学生朋友们比较困扰的问题,平常的考试、作业中经常出错。下面是它们的一些用法:

1、other 指其余的人或物,所有格是 other's,复数形式是 others;the other

指"两个人或物中的另一个",其复数形式是 the others;others相当于"other + 名词",所以不能充当定语,修饰名词。others指整体中去掉一部分后剩余的部分,但不是全部的,即 some...others (一些...其余的人...);the others 强调整体中除去一部分后剩余的全部,即some...the others.

2、another泛指三个以上的不定数目中的"另外一个"。由 an 和 other 合 并构成,所以不能和冠词连用。another 修饰单数名词,比如:another pencil.

3、any other 指除去本身以外的"任何其他的人或物",后面要用名词的单数形式。

24) 表示时间的 in、on 与 at

in, on 与 at 都可以和表示时间的词(组)连用。

1. in 表示时间的一段或较长的时间。如:

in the morning 在上午 in May, 2004 在2004年五月

in a week 在一周之内(后)

It's Sunday, I can finish it in two days.

现在是星期天,我能在两天后完成。(星期二)

Rome was not built in a day. 罗马不是在一天内建起来的。

2. on 主要指在具体的一天。如:

on Sunday 在星期天 on May Day 在"五一"节

on a hot afternoon 在一个炎热的下午

He arrived in Beijing on April 26,2004.

他于2004年4月26日到达北京。

3. at 表示时间的一点或比较短的时间。如:

at 8:00 在八点 at noon 在中午

I always get up at 6:00 every morning. 我总是每天早晨六点起床。

It's always warm at this time of year. 每年的这个时候总是暖和的。

37) a lot of(lots of)与many,much

1.a lot of意为"许多、大量",相当于lots of.它既可以修饰可数名词,又

可以修饰不可数名词。如:

I have a lot of friends in China. 我在中国有很多朋友。

The old man has lots of money. 那位老人有很多的钱。

2.many意为"许多".它用来修饰可数名词。如:

Do you have many beautiful skirts? 你有很多漂亮的裙子吗?

3.much意为"大量".它用来修饰不可数名词。如:

4.a lot of(=lots of)用在肯定句中,而many,much不受限制。如果将一个含有a lot of(=lots of)的肯定句改为否定句或疑问句,要将它们改为many或much。如: We can see a lot of birds in the tree.

---We can't see many birds in the tree. 我们在树上看不到很多鸟儿。

He wants lots of soda.

---Does he want much soda? 他需要许多汽水吗?

35) how many与how much

---How many people are in your family? 你家里有几个人?

---How many classes do you have every day? 你们每天上几节课?

2.how much也是表示"多少",但它对不可数名词进行提问。如:

3.how much还可以对价格提问,表示"多少钱"的意思。如:

The yellow T-shirt is only 35 yuan.

---How much is the yellow T-shirt? 那件黄色的T恤衫多少钱?

36) with的几个用法

1.with表"和、同、与"。如:

Can you go to the park with me? 你能和我一起去公园吗?

Don't write with the red pen. 不要用那支红色的钢笔写字。

4.注意:exercise指具体运动或体操时是可数名词,复数形式为exercises;

29) sometime,sometimes,some time与some times

记忆:sometimes(有时)some times(好几次)sometime(某一次)some time(一段) 口诀:分开是一段,相连为某时。分开s是倍次,相连s为有时
