一般现在时中的第三人称单数形式

在一般现在时中，当主语是第三人称单数时，谓语动词要用第三人称单数形式，即常在动词原形后加-s或-es。

什么是一般现在时？一般现在时的基本用法有哪些呢？

【一般现在时的功能】

1.表示事物或人物的特征、状态。如：The sky is blue.天空是蓝色的。

2.表示经常性或习惯性的动作。如：I get up at six every day.我每天六点起床。

3.表示客观现实。如：The earth goes around the sun.地球绕着太阳转。

标志词（时间状语）：always, every week (day, year, month…),

once a week, every…, sometimes, at…, on Sunday uauslly

②Beijing is in China. 北京在中国。

③Uncle Wang often makes cakes. 王叔叔经常做蛋糕。

三、单数可数名词或"this / that / the+单数可数名词"作主语时，是第三人称单数。如：

①A horse is a useful animal. 马是有用的动物。

②This book is yours. 这本书是你的。

②"I" is a letter. "I"是个字母。

动词第三人称单数+s或+es的规则：

1. 一般情况下在动词后直接+s。

2. 以ch, sh, s, x, o结尾的+es。

3. 以“辅音字母+y”结尾的把y 变i加es。

4. have的第三人称单数为has。

关于do和does的使用方法：

1）第三人称单数用了does 后面就不用动词的s形式了,而用动词原形.

2）变为疑问句,要在句首加"do" does ; 变为否定句, 要在动词前面加"do not ,does not", 可以简写为"don't". 背：I do, you do, we do, they do, Jack and Tom do. He does, she does, it does, lily does.

（三）含有动词第三人称单数形式的句子变否定句和疑问时怎样变？

【注意：】只要句子中出现do, does,don’t,doesn’t, 句子中原来的实意动词要用原形例如：He likes apples. (改成否定句)

He doesn’t likes apples。(错)

He doesn’t like apples。(对)

A 否定句：（1）当主语是第一，二或复数时，主语+ don't +动词原形(+其它)。如：

I don't like bread.

（2）当主语为第三人称单数时，要用doesn't构成否定句。如：

He doesn't often play.

B 一般疑问句：（1）当主语是第一，二或复数时，Do +主语+动词原形+其它。如：

Do you often play football?

- Yes, I do. / No, I don't.

(2) 当主语为第三人称单数时，要用does构成一般疑问句。如：

- Does she go to work by bike?

- Yes, she does. / No, she doesn't.

C特殊疑问句：疑问词+一般疑问句。如：

How does your father go to work?
