动词第三人称单数讲解及练习

动词第三人称单数形式讲解

1、什么是第三人称单数？

人称可分为三类：第一人称、第二人称和第三人称

第一人称： I we

第二人称： you(你或你们）

第三人称： he他、she她、it它、they（他它她们)和人名称谓类（如：Peter、Jane、my father 等）

结合以上知识，第三人称单数就是he、she、it、人名、称谓。

2、动词为什么要变成相应的三单形式？

在一般现在时中，跟在第三人称单数后面的动词也要变成相应的三单形式，例如：

I watch TV every day. 如果主语是三单，动词要变化：

-------He watches TV every day.

She watches TV every day.

Jane watches TV every day.

3、实义动词三单的变化规则

1、一般情况下直接加s，如speak-speaks like-likes play-plays

2、以s x sh ch o结尾的加es，如 wash-washes go-goes do-does watch-watches

3、以辅音字母+y 结尾的，改y 为i 再加es，如 study-studies，try-tries

4、特殊变化，如 have-has

4、does和doesn’t 在句子中的用法

否定句：主语+don’t/doesn’t+实义动词原形+（其他）。如：

I don’t watch TV. 我不看电视。

当主语为第三人称单数时，要用doesn’t 构成否定句。如：

He doesn’t watch TV. 他不看电视。

注意doesn’t后面用动词原形watch，而不是watches

一般疑问句：Do / Does+主语+实义动词原形+（其他）。如：

Do you watch TV? Yes I do. / No I don’t.

Does he watch TV? Yeshe does./NoI doesn't.
