Unit 7 Will people have robots
一、语法　
一）一般将来时　will+ 动词原形
学习目标：学会运用will+ 动词原形预测未来。
学习内容：
１、will+动词原形用法：常用来陈述将 ( http: / / www.21cnjy.com )来某个时间将要发生的动作或存在的状态，也可表达意愿，即“愿意／会做某事”，句中常有表示将来时间的时间状语，如：tomorrow, tomorrow morning , next week / year / month / spring , soon ,
in two days (两天以后 ) , when you grow up 等。如：
1）We will have a sports meeting tomorrow. 明天我们要开运动会。
2）We will build a house next week . 下周我家盖房子。

4）Don’t worry. I will help you. 别担心。我会帮助你的。(表达意愿)
5）-- Come early tomorrow. --I will. --明天要早来。-- 我会的。（表达承诺)
２、句子构成：
肯定句：主语＋will+ 动词原形＋其他…
We will build a house next week.
否定句：主语＋will not + 动词原形＋其他…
We won’t build a house next week .
一般疑问句：Will +主语+ 动词原形＋其他…？
Will you build a house next week Yes, I will. / No, I won’t .
特殊疑问句：当特殊疑问词做主语时，特殊疑问句构成是：特殊疑问词＋will+ 动词原形＋其他…？如：
Who will build a house next week
当特殊疑问词不是句子的主语时，特殊疑问句构成是：特殊疑问词＋will+ 主语＋动词原形＋其他…？如：
What will you do next week
When will you build a house
３、当主语是第一人称时，也可以用 “ shall +动词原形”表将来。
４、“be going to + v.原形 ( http: / / www.21cnjy.com )”结构和 “ will+ v.原形”的区别：二都都可以表达将来发生的事，一般不加区分，只是在下列情况下，需要注意：
1、用be going to，不用will的两种情况：
1）当谈论计划打算时，用be going to，不用will，如：
①What are you going to do when you grow up 你长大后打算做什么？我打算当老师。
②I’m going to swim tomorrow. 我打算明天去游泳。
2）谈论根据现在所知，预计不久肯定会发生的事情时 ，用be going to，不用will，如：

②He is packing his ba ( http: / / www.21cnjy.com )g. He is going out.他在打点行装，他要外出了。
③The car is going to turn over. 车要翻了。
④He has reach ( http: / / www.21cnjy.com )ed Dangji, he is going to be here in ten minutes. 他已经到党集了，十分钟后他就能来到。
2、下列情况下用will，不用be going to：
1）在有条件从句 ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网" \t "_blank )的主句中，一般不用 be going to, 而多用will, 如：
If you work really hard, you will be famous.
2)根据说话者的见解和观点对未来作出预言时
I think Tom will study hard from now on.
3）在说话时临时作出的决定时，一般用will的缩略式’ll.
I think I’ll go ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网" \t "_blank ) to bed.
— Come to supper. — OK, thanks. I’ll bring a bottle.
4）表示意图、提议、许诺 ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网" \t "_blank )、自愿做某事或坚持做某事时 ，带有感彩，如：

7)表示习惯和规律时
①The baby will cry when her mother leaves.
②Man will die.
5、there be结构的一般将来时
1）There be 句型的be ( http: / / www.21cnjy.com )going to 结构“There is / are going to be” 常用来表示某地将存在某人或某物。注意句型中be going to 后面的be不能改为have；遇到名词单数或不可数名词，用There is going to be，遇到复数可数名词用There are going to be；例如：
①There is going t ( http: / / www.21cnjy.com )o be a football match next Saturday in our school.下周六我们学校将有一场足球比赛。
②There aren’t going to be any apples in winter. 冬天将没有苹果。
③Is there going to be milk tomorrow 明天将会有牛奶吗？
Yes, there is . / No, there isn’t. 是的，将会有。/ 不，不会有。
2)there will be 是there be句型的一般将来时，用来表示某地将存在某人／物。如：
①There will be a book on the desk tomorrow.
②There won’t be a book on the desk tomorrow.
③Will there be a book on the desk tomorrow
Yes, there will. / No, there won’t.
例题解析：
（ ）1、 a football game in our school tomorrow.
A. There will have B. There is going to have
C. Have D. There is going to be
(分析：答案是D。根据句中时间状语tomor ( http: / / www.21cnjy.com )row可知应用一般将来时态，根据句意可知本句要表达的是“某地将存在”，要用There be句型；而There be句型的一般将来时有两种结构，即There is / are going to be和there will be，答案选项中没有there will be，只有There is going to be，故选D)
（ ）2、Look at the baby ! I’m afraid he cry(哭).
A. will B. is going to C. should D. does
(分析：答案选B，根据现在所知推断将要发生的事用be going to , 不用will)
( ) 3、Tom s ( http: / / www.21cnjy.com )aid to his mother, “ I play computer games any more.
I study harder and pass the exam next time.”
A. won’t... am going to B. am not going to ... am going to
C. won’t... will D. am not going to ... will
（分析：答案选C，表达许 ( http: / / www.21cnjy.com )诺或自愿做某事用will，本句是Tom给妈妈的保证，保证以后不再玩游戏，而要努力学习，争取通过考试，带有明显的情感色彩，所以用C答案）
（ ）4、I come to the meeting if it rain tomorrow.
A. will... doesn’t B. am going to ... won’t
C. will ... won’t D. am going to ... don’t
(分析：答案A。本句是含有条件状语从句的复合句，由于时间状语是将来，句结构应该是：主句用一般将来时，从句用一般现在时；而且，在有条件从句 ( http: / / www.21cnjy.com" \o "欢迎登陆21世纪教育网" \t "_blank )的主句中，一般不用 be going to, 而多用will,所以本题答案应该是A)
二）运用“more / fewer / less”修饰名词
１、more是……和…....的比较级，意思是“更多”，所以可以修饰可数名词复数和不可数名词，也可以修饰某些动词，如：
①I will have more apples than you tomorrow. 明天我比你的苹果多。

③People will use th ( http: / / www.21cnjy.com )e subways more in the future. 将来人们使用地铁多. (more修饰动词use)

In the movies, they ca ( http: / / www.21cnjy.com )n help with the housework and do jobs like working in dirty or dangerous places.

In Japan, some robots can walk and dance .

范文：
We will have mor ( http: / / www.21cnjy.com )e and more robots in life. And our life will be more and more relaxing.
Robots will be in d ( http: / / www.21cnjy.com )ifferent kinds of shapes. And as long as they can do work well, they can be in any kind of shapes.
Now they can do s ( http: / / www.21cnjy.com )ome simple or dirty jobs. They can do such jobs over and over again. Robots in the future will be able to do more difficult jobs than now. For example, they will be able to wash dishes, wash clothes, cook, watch transportation, do the cleaning. They will be able to do any dirty or dangerous jobs and even any job that human won’t want to do or can’t do.
Robots can do so m ( http: / / www.21cnjy.com )any jobs in the future, so we will have more and more vacations, and we will be more and more relaxed. But we will have fewer and fewer jobs to do, and more and more people may lose their work. But I don’t think robots can take the place of humans.
I hope we can make ( http: / / www.21cnjy.com )life better by making robots. And I’m sure we can.
