一般现在时(第三人称单数形式_)及练习

一般现在时（第三人称单数形式）

Hello, boys and girls.我是一般现在时，你们想知道我的故事吗？Let me tell you!

首先，介绍我的本领。我的本领有三样：

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。

第二，请看我的面目--构成：

1. be动词：主语+be(am ,is ,are)+其它。如：I am a boy.我是一个男孩。

2.行为动词：主语+行为动词(+其它)。如：

We study English.我们学习英语。

当主语为第三人称单数(he, she ,it)时，三单变化：

1．多数在动词后加s ，play—plays like—likes

2．以s，x，sh，ch，o结尾的动词加es go—goes wash—washes 3．

4．以辅音字母加y结尾，把y改i再加es，fly—flies 。元音字母加y结尾的，直接加s，play-plays。

5．特殊：have-has

第三，我的变化--否定句、一般疑问句、特殊疑问句：

1.be动词的变化。

否定句：主语+ be + not +其它。

如：He is not a worker.他不是工人。

一般疑问句：Be +主语+其它。

如：-Are you a student? -Yes. I am. / No, I'm not.

特殊疑问句：疑问词+一般疑问句。如：Where is my bike?

2.行为动词的变化。

否定句：主语+ don't( doesn't ) +动词原形(+其它)。如：I don't like bread. 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.

一般疑问句：Do( Does ) +主语+动词原形+其它。如：

- Do you often play football?

- 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 go to work by bike?

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

特殊疑问句：疑问词+一般疑问句。如：How does your father go to work?
