哈佛英语学科七年级第五单元讲义

知识点一：

1. have “有” 后跟人或物，表示所有关系，其主语多是人，且是一，二人称单复数和第

三人称复数的人。如果主语是第三人称单数，将have变为has. 即：

I /You/They have… He /She has…

①They have a pen. ②He has a ruler.

2. have/has 的疑问句和否定句借助于do /does. 即一般疑问句：

①Do +主语（非三单）

+have ….? Do they have a pen? Yes, they do. /No, they don’t.

② Does +主语（三单）

+have ….? Does he have a ruler? Yes, he does./ No, he doesn’t. 否定句：

①主语（非三单）+don’t +have ….They don’t have a pen.

②主语（三单）+doesn’t +have …. He doesn’t have a ruler.

3. 注意：加了does后，谓语动词不再用单数，has用have

She has a dictionary. She doesn’t have a dictionary.

Does she have a dictionary?

例题讲解：用have 或has 填空

1. We ______ friends , parents and teachers.

2. She ________ an apple.

3. Do you ________ a ball?

4. She doesn’t _________ a ball.

5. Mary ________ a dog.

6. The dog __________ three ears(耳朵)。

课堂练习：句型转换

1. He has a soccer ball. (主语改为I)_______ ________ a soccer ball.

2. She has a basketball . (改否定句)She ________ ________ a basketball.

5. David doesn’t play basketball every day. (改肯定

句) David ________ ________ every day.

1. Let’= Let us “让，允许”

2 Let +宾格人称代词或名词+动词原形。让某人做某事。

Let him go home.

②Let +宾格人称代词或名词+not+动词原形。让某人不做某事。
