时态表示时间和状态
时间:过去,现在和未来
状态:一般时,进行时,完成时
组成9种时态,其中将来完成时不常用,剩余8个时态。

一般时态:表示过去的(did),现在的(do/does) 和将来的(will do / be going to do),发生的某件事,这个时间并不是特指,不对时间做强调。
举例:一般过去:I went shopping last night;
一般现在:I watch TV;
一般将来:I will go USA tomorrow

进行时态:过去(was/were doing) 现在(am/ is /.are doing)将来(will be doing)
进行时态与一般时态相对应,强调那个特定时刻正在干什么。
举例:过去进行:I was sleeping when you came.
现在进行:I am playing games now.
将来进行:I will be running fast in the next hour.

完成时态:过去(had done)现在(have done)将来(will have done)
完成时态表示时间与时间之间的关系。过去完成时表示站在过去看过去;现在完成时表示站在现在看过去;将来完成时表示站在将来看过去。
举例:过去完成:She had gone when you came last night.
现在完成:I have done all my work
将来完成:I will have finished my paper next week.

补充一种时态:现在完成进行时(have been doing)。表示站在现在看过去且一直持续到现在还会持续下去的动作。
I have been making contributions to my country for ten years
