动词的时态有很多。初中阶段主要掌握八种:一般现在时、一般过去时、现在进行时、过去进行时、一般将来时、过去将来时、现在完成时、过去完成时。
1.一般现在时
1)一般现在时态的构成:主语是I, we, you, they和名词复数时作谓语的行为动词用原形。主语是he, she , it和名词单数时,作谓语的行为动词的词尾变化如下:
一般情况 +s
以s, x, ch, sh 或 o结尾 +es
以辅音+y结尾 去y变i+es
2)一般现在时态的肯定句、否定句和疑问句形式(以be和like为例):
主 语 肯 定 式 否 定 式 疑 问 式
第一、二人称和第三人称复数以及名词复数 I am a student.
We/You/ They are students.
He/ She is a student.
I / We/ You/ They/ like music.
Many people like music. I am not a student.
We/You/ They are not students.
He/ She is not a student.
I / We/ You/ They/ don’t like music.
Many people don’t like music. Are you a student.
Are you/ they students?
Is he/ she a student?
Do you/ they like music?
Do many people like music?
3)一般现在时态的用法:
现阶段经常性,习惯性的动作 。例如:
I get up at six every morning.
He plays tennis once a week.
现在的状态 例如:
My mother is a teacher. She teaches English in a school.
客观真理 例如:
The earth goes around the sun.
4)常用于一般现在时态的时间状语:
often usually sometimes always every day never in the morning 等。

A. didn’t work B. doesn’t work C. won’t work D. can’t work

2.______ the bus until it ______..
A. Get off, stops B. Get off, will stop C. Don’t get off, stops D. Don’t get off, will stop
