动词第三人称单数形式讲解
一、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
第三人称：he、she、it、they和人名类（如：Peter、Jane、my father等）结合以上知识，第三人称单数就是he、she、it和单个的某人，也包括单个的动物、东西等。
二、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.
三、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
四、does和doesn’t 在句子中的用法
否定句：主语+don’t/doesn’t+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+动词原形+（其他）。
如：
Do you watch TV? Yes, I do. / No, I don’t.
当主语为第三人称单数时，要用does 构成一般疑问句。
如：Does she watch TV? Yes, she does. / No, she doesn’t.
特殊疑问句：疑问词+一般疑问句。
如：
How do you go to school? By bike.
How does Jane go to school? By bus.
