精选的一般现在时的构成

  (一)时态构成:

一般现在时主要由动词的原形表示,如果主语是第三人称单数,则在动词原形后加-s或-es。

(二)时态的用法:

1、表示经常发生的动作、存在的状态和现阶段的习惯

常用的时间状语有:often, sometimes, usually, always, seldom, in the morning, every day, on Sunday 等。如:

He is always ready to help others.

The students have sports at five every afternoon.

Does he work hard?

2、表示不受时间限制的事实或普遍真理

Three plus two is five.

A plane is faster than a car.

China is in Asia.

Light travels faster than sound.

3、在含时间和条件状语从句的复合句中

主句用一般将来时,从句则用一般现在时表示将来动作。如:

I will stay at home if it rains tomorrow.

She’ll go to see him as soon as she arrives.

When they come, they’ll tell you something important.

4、在含宾语从句的复合句中

尽管主句用过去时态,但如果宾语从句所述内容是客观真理,从句谓语动词仍然用一般现在时。如:

The teacher told her pupils that the sun rises in the east.

5、表示已经安排或计划好将来必定会发生的动作或存在的状态

一般用be, come, go, arrive, leave, start等动词。如:

My birthday falls on May 2.

The meeting is at 2:00 p.m.

His ship leaves at 9:00 a.m.

6、图片说明、电影说明、解说戏剧内容及场景动词常用一般现在时。如:

Scene 1 ( Mary and Miss Green are in the professor’s room-a large ,pleasant room with many books. There is a big desk near the window. )
