九年级英语时态复习

- 1 - 一般现在时

一．一般现在时用于表示现在的状态，如：He is twelve./She is at work./My father is a doctor. 表示经常的或习惯性的动作，通常与alwys,usually,often,sometimes,seldom,three times a day, every day(week,month---)等表示频度的时间状语联用

如：I get up at 6:30 every day.

表示主语具备的性格和能力等，如：She likes noodles. / They speak French. 表示客观事实或真理，如：The sun rises from the east and set in the west.

一般现在时的构成。

1.be动词。

在一般现在时中be动词有三种形式:am, is, are. 其中am只用于主语是I的情况；主语是第三人称单数用is；其他人称用are。第一人称：指“我”、“我们”，即I，we。

第二人称：指“你”、“你们”，即you。第三人称：除第一、二人称外都是第三人称。第三人称单数：包括代词he，she，it，可数名词单数和不可数名词做主语时都是第三人称单数。第三人称复数：包括代词they，可数名词两个或两个以上为复数，不可数名词没有复数形式。

如：I am a student. You are 11 years old. He is at work. She is a Japanese girl. It is fine today. They are from Korea.

2.如果谓语动词不用be动词。那么，当句子的主语为单数第三人称以外时，在肯定句中，谓语动词用原形。

如：I do my homework every day.

We study Chinese, Math and English at school. You work in a supermarket，don’t you? They go to school bu bus. The boys often play basketball on the playground. 当主语为第三人称单数时，在肯定句中，谓语动词要用第三人称单数形式（简称三单形式）。如：Mr. Bush usually goes to work in his car.

Our teacher wears a pair of glasses. Time flies fast. Mother likes apples.

动词三单形式的变化规则有：

1）直接加s：give—gives,ask—asks, take—takes, get—gets, write—writes

2）s, x, sh, ch, 结尾的, 加es：fix—fixes , pass—passes, watch—watches, wash—washes,

3)辅音字母+y结尾的，把y变成i再加es：study—studies, carry—carries, worry—worries

4) 特殊变化：have—has do--does go--goes

3．一般现在时的否定句，如句中有am, is, are，直接在后面加not；没有的，要在谓语动词前要加助动词don’t或doesn’t。主语为第一、第二人称和第三人称复数的，用don’t；主语为第三人称单数的，用doesn’t，但谓语动词要恢复原形。

如：We are at home. We aren’t at home.

The lady is from Canada. The lady is not from Canada.

I want to go to the party. I don’t want to go to the party.

They have some cartoon books. They don’t have any cartoon books.

The bull runs faster than the lion. The bull doesn’t run faster than the lion.

Mike likes swimming and skating. Mike doesn’t like swimming or skating.

4．一般现在时的疑问句，如句中有am, is, are，把其提到主语前即可；没有am, is, are 的，要在主语前加助动词do或does。第一、第二人称和第三人称复数作主语的，用do；第三人称单数作主语的，用does，谓语动词要恢复原形。

如：You are from Singapore. Are you from Singapore? –Yes, I am. / No, I’m not. The teacher is in the office. Is the teacher in the office? –Yes, she is. / No, she isn’t.

You always keep their classroom clean. Do you always keep their classroom clean?

--Yes, we do. / No, we don’t. Liu Xiang runs very fast. Does Liu Xiang run very fast? --Yes, he does. / No, he doesn’t.

She has some good friends. Does she have any good friends?

-Yes, she does. / No, she doesn’t.
