Unit5 Do you have a soccer ball

话题:和朋友度过时光

教学目标:1. 学会用have对物品的所属进行提问和回答

2. 讨论自己喜欢和不喜欢的球类运动,说明原因

3. 学会用Let's提建议

重点:一般现在时态中have的用法

难点:have的用法

I have; He/She has…;

Do you have a… Yes, I do. / No, I don't.

Does he/she have… Yes, he/she does. / No, he/she doesn't.

知识点:

1. Do you have a ping-pang bat

这是一个一般现在时态的疑问句,have在句中是实义动词。如果谓语是实义动词,变一般疑问句,常借助于助动词来提问,主语为第三人称单数借助does,其他情况均用do。do 或does在这里没有实际的意义,仅仅用来帮助构成一般疑问句。

谓语动词为实义动词的一般疑问句句型:Do/does+主语+动词原形

Do you like bananas

陈述句变为一般疑问句的规律 借 调 改 加

I like bananas. Do you like bananas

He likes bananas. Does he like bananas

She wants a book. Does she want a book

It likes apples. Does it like apples

回答这种一般疑问句时,肯定Yes, 主语(代词)+do/does. 否定No,主语(代词)+do/does.

---Do you know him

---Yes, I do./No, I don't.

练习:

1. ____ you have a pen Yes, I ____.

2. ____they ____ apples No, they ____.

3. ____he ____ a basketball Yes, he____.

4. ____she ____ 2 books No, ____ ____.

5. ____Amy ____ 5 eggs No,____ ____.

6. ____Mike____ a baseball Yes,____ ____.

7. ____ Peter ____ a tennis ____,he doesn't.

8. ____ the boys ___ a volleyball ____,_____ do.

9. ____ Jim and Alice ___ a computer No,____ _____.

we ____ a soccer ball Yes,_____ ______.

have为及物动词,意为"拥有,有'第三人称单数形式为has.在它的后面加上某人或某物,表示"有……'。常用句型"某人/某物+have/has+某物'表示某人或某物有某物。

(1) have用于复数名词前,第一人称,第二人称或第三人称复数代词作主语的句子之中。

(2) have/has作谓语时的句型转换

否定句:主语+don't/doesn't +have…

一般疑问句 Do/does+主语+have…

肯定回答: Yes, 主语+do/does.

否定回答: No, 主语+don't/doesn't.

(3) 当have/has后的名词被some修饰时,在否定句和疑问句中some要改成any.

I have some good friends.

I don't have any good friends.

(4) have/has与there be的区别

在表示这一结构时很多学生容易错误的把There 和have / has 连用,因此要区分出他们的含义和用法:There be 结构只是表示一种状态也就是一种存在的关系,而have /has 则表示拥有即使一种所属关系也就是“某人用有某物”。例如 There is a book on the desk.只是表示这本书在桌子上这一状态,而书不是属于桌子的,如果把书放到其它地方,这状态就不存在了。I have a book about aliens.则表示这本书是我的,不管这本书在哪里它都是属于我的,这就说明我拥有了这本书,哪怕是别人借走了,它都还是属于我的。这样举例说明让学生很清楚的了解到There be 和 have/ has 的区别。并且There 当表示存在的“有”时后面只能跟be 的相应时态。

(5) have/has含义很多,可表示“吃,喝”等,还可构成许多常用的短语,其后跟不同的名词作宾语时,含义也发生变化。

have lunch have a look have a glass of milk have a party

练习

( )1.—Do you have a TV? —________. A..Yes,it is B..Yes,we have C..Yes,we do

( )2.—Does John like tennis? —No,___________. does doesn't

( )3.—Do your friends have any story books

( )4.—Do you have any empty bags

,do ,don' t have any C. Yes, have ,have

( )5.—___________you___________any apples

—Yes,I___________.

;have;do ;have;do ;having;am ;have;are

2. Let's go. 咱们走吧!

let's是let us的缩写形式,表示"让我们……吧'。用于提出建议或征求别人的意见。us是we的宾格,房子let后作宾语。该句型结构为let's do sth.意为"让某人做某事',

该句为祈使句,句型结构是Let sb. do sth."让某人干某事。

肯定回答用"OK.', "All right.', "That sounds good.', "A good idea.'

人称

第三人称

单数

复数

let us与let's

"Let's"用于提出建议,其中"us"包括对方在内。如:Let's go.我们走吧!(说话人提议对方和自己一起走,这句话等于I(We)suggest that you and I(we)should go.)若要 变成反意问句,应在这个句型后加 shall we, 表示进一步征求对方的意见。

例如:

1. Let's start early,shall we 我们早点动身,好吗

2. Let's begin our discussion,shall we 我们开始讨论,好吗

"Let us"中的"Let"等于"Allow"(允许),这时"Let us..."="Please allow us to do...",请求对方允许自己干某事,这时"us"不包括对方在内。

例如:

Let us go. 让我们走吧!(请求对方让我们走,而不是我们和对方一起走,这句话等于 Please allow us to go.

反意疑问句时

let's ……shall we (we包括对方)

let us ……will you (由于us不包括对方,因此反意疑问句用you )

3. That sounds good. (那听起来不错。)

sound是系动词,意为“听起来”,后接形容词或名词。

sound的第三人称单数形式是sounds.

类似系动词还有look, taste, smell, fell

He looks very happy. 他看起来很高兴。

The food tastes delicious. 这些食物尝起来很美味。

4. We have many sports clubs. (我们有许多体育俱乐部。)

many用作形容词,表示“许多的、大量的”,后接可数名词的复数。

eg:

He has many books.

sports作名词表示”体育活动”。play sports 做运动

sports作形容词表示”体育运动的” sports clubs 体育运动俱乐部

5. interesting 形容词,意为“有趣的,令人感兴趣的”, Miss liu's class is interesting.

boring

difficult 困难的,反义词是easy It's a difficult question.

fun 好玩的 That sounds fun.

这几个都是形容词,用来描述一项活动或一件事情,表达对某一活动或事情的看法,在句子中可作定语,表语等成分。

interesting, boring都是由动词去e或者直接加-ing构成的形容词,可用来作定语修饰物或事情。修饰人的时候,多由加(e)d构成的形容词,interested,bored.

6. watch TV 看电视

watch… on TV 在电视上看…节目 on TV 意为“在电视上”不加定冠词the, 但是表示在电脑上,在广播上时,要加定冠词the. on the computer, on the radio.

eg: We can watch ball games on TV.

watch 做可数名词,意为“手表”,复数形式是watches.

He has two watches. 他有两块手表。

7. It's easy for me. 对我来说很容易。

easy形容词,意为“容易的,不费力气的”,反义词为difficult.

It's easy for me=It's not difficult for me.

for介词,意为“对……来说”,用于it +be+形容词+for+sb.句式结构中。如果该句式后跟动词时,要用不定式结构,即:it+be+形容词+for sb.+to do sth. 意为“做某事对某人来说是……的”。

7. My brother and I are in the same school. 我哥哥和我在同一所学校。

这主要是英语习惯上的用法。当两个以上的人称代词并列时其排列顺序一般为you, he, she, I,而复数时为we, you, they:如男女并列时,应先男后女,如:He and she …如果在表示不好意思,承担责任时,单数时用,I, he, she, you, 复数时用They, you, we, 如:

Tom and I are good friends.

You, he and I must go to play the game for our team this afternoon.

We, you and they have been there before.

I, he and you have to pay for it.

same形容词,意为“相同的,同一的”。反义词为different,意为“不同的”。

same前一般带定冠词the,其后的名词用单数,different后面的名词用复数形式。

We are in the same class.

They are in different classes.
