助动词do/does辅助实义动词构成疑问和否定

Learning by comparison(通过对比学习，发现总结规律)。

Know sports, love sports and love life. 1.

含助动词的一般疑问句及其答语。

2.

助动词原形do及其第三人称单数does的用法与区别。

1.

理解并掌握含助动词的一般疑问句及其答语，助动词原形Extra-lingual 非语言目标

教学重点

教学难点

do及其第三人称单数does的用法与区别，以及助动词使用的先决条件是辅助实义动词构成疑问和否定。

2.

理解并掌握英语句子中主谓语人称与数的变化

教学过程

Step 1复习；以旧带新

根据图片，老师让学生集体讨论，让同学们回忆所学与球类运动相关的单词和词组，巩固所学知识。

T：Now，let's think of the words and phrases about sports. What do you know about sports things? Ss：Basketball，soccer ball，ping-ping bat... Ss：play Basketball/soccer ball/ping-ping bat...

设计意图：通过图片联想让学生快速回忆起所学的有关球类运动的词汇，唤起学生学习的兴趣和热情，同时也为接下来的学习作好了铺垫。

Step2 视频导入

设计意图：以动画视频导入，引出do you have...？句型。吸引学生注意力，激发学习兴趣。

Step2 自主朗读Grammar Focus，找出异同，发现规律。

Do you have a baseball? Do you have a ping-pong bat? Does she have a tennis ball? Does he have a soccer ball? Do they have a basketball? Yes, I do. / No, I don’t. I have a volleyball. Yes, I do./ No, I don’t. I have a ping-pong ball. Yes, she does./No, she doesn’t. She has a baseball. Yes, he does./ No, he doesn’t. He has two ping-pong bats. Yes, they do./ No, they don’t. They have a volleyball.

Step 3 小组合作，探究规律

如何变否定

I have a basketball.

I don't have a basketball. He has a soccer ball.

He doesn't have a soccer ball. They have a baseball.

They don't have a baseball.

如何变疑问

I have a basketball.

Do you have a basketball? He has a soccer ball.

Does he have a soccer ball? They have a baseball.

Do they have a baseball?

规律;借助Do/does

师生共同探究总结：

1.

do/does是助动词，无实在意义，用来辅助实义动词构成否定句和疑问句，不能单独使用。

2.

Do引导的一般疑问句，其结构为“Do+ 主语+动词原形

+其他？”。

肯定回答：Yes, 主语+do; 否定回答：No,主语+don't.

3.

Does是do的第三人称单数形式，当主语为第三人称单数时，用does。

Does引导的一般疑问句，其结构为“Does+ 主语+动词原形

+其他？”。

肯定回答：Yes, 主语+do; 否定回答：No,主语+don't. 4.

do not = don't

does not= doesn't

设计意图：通过小组合作讨论解决以上问题，从问题中发现语法规律，总结语法点。培养合作学习精神和探究解决问题的能力。

Step 4 举一反三

通过例子证明以上结论。

Step 5 Chant

以chant形式对以上规律进行概括，简易好记，加深印象。

Step 6 合作探究。人称代词与do和does的关系

Do：

I they we you Does：

he she it Eric

以两个小游戏来对探究人称代词与do和does的关系进行理解和巩固。游戏采取积分制，激发学生的小组荣誉感和积极性。

Step 7 测一测。通过3b来巩固do和does的使用并进一步引出let使役动词的用法和play的用法。

A:

John have a

soccer ball? B: No, he

. A:

he have a ping-pong bat? B: Yes, he

.

I think he has a ping-pong ball, too. A: Hmm…let’s ask.

探究结果; Let’s play basketball.

咱们打篮球吧。

★本句是以let引导的祈使句，let是使役动词，意为“让某人做...”，结构为“Let sb. do sth.”，let后面动词用原形。如：Let’s watch TV.

Let’s play soccer.

咱们踢球吧。

★play是实义动词，意为“玩”，表示进行某项活动。

play后接乐器类名词要加the，接球类、棋类名词不加the

Play+球类名词/棋类

play the piano

Play+定冠词

the+乐器名称

play volleyball

play chess Step 8 接龙游戏

小组接龙：组内成员按照图片顺序依次用句型let's play （the）...描述下面六幅图，哪一组最快最好完成任务，哪一组获胜。

Step 9学以致用。看图用have/has,do/does填空

A: Do you have a _________? B: Yes, I ______. A: ____you _____a ____________? B: No, I _______. A:

___

he _____ a__________? B: Yes, _________.

A:

___

he _____ a ____________? B: No,

_________.

Step 10 情感升华

积累名言警句

Life lies in movement.

Step 11 Summary总结本课

由学生根据思维导图来总结本课，锻炼学生总结概括能力
