一般疑问句和否定句

一般疑问句，否定句

课题一：一般疑问句general question

重点：辨别一般疑问句，掌握一般疑问句语法结构和使用方法。

难点：1.一般疑问句的句子结构。

2.一般疑问句和陈述句之间的转化。动词时态的变化。

教具准备：教学讲义练习题。

教学过程：

1.复习：P17,P32

重新朗读课文。复习单词和语法。

2.提出课题：

Does...like...(doing)?

Yes,...does./No,...doesn’t.

Is/Are...(doing)?

Yes,...is/are./No,...isn’t/aren’t.

由以上例句总结一下一般疑问句的定义:一般疑问句是疑问句的一种。它是一般只用yes （是）或no（否）来回答的句子。朗读一般疑问句时用升调。

3.教学步骤：

a.举出更多例句.

Eg1. 问句：Is this your pen？

肯答：Yes，it is.

否答：No，it isn`t.

Eg2. 问句：Are these your books？

肯答：Yes，they are.

否答：No，they aren’t.

Eg3. 问句：Can you speak English?

肯答：Yes，I can.

否答：No，I can’t.

Eg4. 问句：Do you likeapple？

肯答：Yes，I do.

否答：No，I don’t.

b.总结一下一般疑问的句子结构及回答。（句子结构的记忆方法：就是讲前面2个词调换位置了。）

Is/Are+主语+其他部分? 。。。是。。。？

Eg1. Is this your pen？

当只有一支笔的时候就用Is, 回答：Yes,it is/No,it isn’t .

当有两只及以上用时用Are,而且要讲这个（this）/那个（that）变为这些（these)/那些（those).笔要加s变成复数。

如：Are these/those your pens?

回答：Yes,they are/No,they aren’t.

② Can/Will+主语+V-原型? (后面动词都用原型）

Eg. You can open the door→Can you open the door?

You will go to school next Monday →Will you go to school next Monday ?

③Do/Does+主语+V-原型？

Eg. Do you likeapple？

Does Mary like cat?

第一，二人称（I,You）用Do; 第三人称(Mary）用Does

Parents等复数也用Do.

举例:我需要现在回家吗？Do i need to go home now?回答：

你父母喜欢英语吗？Do your parents like English?

Alice喜欢花吗？Does Alice like flower？

C.辨别以下是否为一般疑问句。

Are you a student?

Is it his pet?

What is that over there?

Can you swim?

Do you have a storybook?

This is a toy bear,I think.

D.将陈述句转化为一般疑问句。

①句子中有Is/Are/can: (some 改成any，my改成your等)

一加：把句中的Is/Are/can.到主语前；

二改：改换主语称谓，即将句中的主语I\my\mine\we\our\ours等第一人称分别改为相应的第二人称you\your\ yours等；

三问号：句末的句号改为问号。如：

Eg6. I am an English teacher. → Are you an English teacher?

Eg7. We can speak English fluently. → Can you speak English fluently?

②句子中没有Is/Are/can (some 改成any，my改成your等)

一加：即在句首加助动词Do或Does；

二改：1、把谓语动词改为原形；2、改换主语称谓（同①）；

三问号：句末的句号改为问号。

Eg8. We read English every morning. → Do you read English every morning?

Eg9. Tom’s father listens to English on the radio every evening. →

Does Tom’s father listen to English on the radio every evening?

特别注意：对于第②一定要注意动词的还原，因为时态与数的变化已经体现在助动词上了。

E.将下面的句子转换为一般疑问句。

1.I am from china. Are you from china?

2.This is my sister ,Nancy. Is this your sister,Nancy?

3.You can have a look. Can I have a look?

4.I play football. Do you play football?

5.Kitty has a yellow purse. Does Kitty have a yellow Purse?

6.There is a birthday cake on the table? Is there a birthday cake on the table?
