一般现在时被动语态的构成:
过去分词的变化形式
一 规则变化
(1) 在动词后加ed:work – worked stay - stayed
(2) 在以-e结尾动词后只加d:close - closed like - liked
(3) 以辅音字母加y结尾的动词,应将y改为i 再加-ed:study -studied carry - carried
(4) 以重读闭音节或r音节结尾且末尾只有一个辅音字母动词,要双写末尾的辅音字母再加-ed: stop -stopped
二 不规则变化
例如 go- gone make-made put-put 等
练习一
把下列句子变为含被动语态的句子:
1. Mr. Li corrects the students' homework every morning.
The students' homework is corrected by Mr. Li every morning.
2. People play basketball all over the world.
Basketball is played by people all over the world.
练习二
It will be two days before the decision_____.
has made B. will be made
C. was made D. is made.
【解析】本题考查被动语态的用法。句意为“在下决心之前,将有两天的时间” 根据语境可知选D。
练习三
— Your classroom is really bright and clean.
—It _____ after school every day.
A. is cleaned B. cleaned C. was cleaned
【解析】动词语态。every day是一般现在时的标志。根据句意,你们教室真的既明亮又干净。每天放学后我们打扫它。此处是被动语态省略了by us。一般现在时被动语态构成:be+动词过去分词。故选A。
---- Drunken drive is dangerous, isn’t it
---- Yeah. That why drunken drivers to prison even without causing accidents.
A. sent B. are sent
C. send D. are sending
练习四
【解析】考查被动语态的用法。依据前面介绍“酒后开车是危险的”,可推断“这就是酒后开车的司机被送进监狱的理由,虽然没有发生事故”,所以用被动语态(be+动词的过去分词),故选B
---Look, what have they done
---Sorry. I think if I __________ another chance, I’ll do it better.
give B. will be given
C. will give D. am given
练习五
【解析】动词语态。I与another chance是被动关系。if引导的条件状语从句,主句用一般现在时,从句用一般将来时。根据句意:看,他们做了什么?抱歉,如果再给我一个机会,我会做的更好。选D。
The Simple Future Tense
一般将来时
我们除了用“be going to+动词原形”可以表示一般将来时外,我们还可以用“will+动词原形”来表示一般将来时.
will 引导的一般将来时:表示将来发生的动作或存在的状态,最基本的结构:will + 动词原形
“主谓(宾)句型”的一般将来时:
肯定句:主语+ will +动词原形+(宾语)+其他
Some day people will go to the moon .
否定句:在will 的后面加not即可。will not 可缩写为 won’t
They won’t use books .
一般疑问句:把will 提到句子主语之前,结尾变问号。
Will students go to school in the future
特殊疑问句:特殊疑问词+will +主语+动词原形+其他?
What will your dream school have
“There be”句型的一般将来时
肯定句: There will be +名词+其他成份
[注意]:无论后面加单数名词或复数形式,be都必须用原形。
There will be only one country.
否定句:在will后面加not.
There won’t be only one country.
一般疑问句:把will提到there之前。
Will there be only one country
Yes, there will. / No, there won’t.
注意:在口语中,所有人称都可以用will.
一般将来时的主要用法:
1、表示将来某一时刻的动作或状态:
We will come to see you the day after tomorrow.
There will be a wonderful show next week.
2、表示将来某一段时间内经常的动作或状态:
The students will come and work in the lab once a week.
We will come and work in this factory every year.
肯定 否定 一般疑问 回答

many presents. I won`t have many presents. Will I have many presents Yes,I will.
No,I won`t.
He will do dull jobs. He won`t do dull jobs. Will he do dull jobs Yes, he will.

No,there won`t.

No,they won`t.
will句式总结:
一般将来时两种基本句式的区别:
在初中阶段来讲,”be going to+动词原形”和“will+动词原形”这两种表示将来时态的结构没什么区别。但在现代英语中,特别是在口语中,表示将来时多用“be going to+动词原形”这一形式。另外他们主要区别在于“be going to+动词原形”表示一个事先考虑好的意图,相当于“打算、计划、准备”,而will则表示未经事先考虑的意图。
