其实英语共有十六种时态，但我们平时比较常用的只有八种，如下：
1.一般现在时: 主语+do/does(现在分词)
e.g We clean the room every day.
2.一般过去时: 主语+did
e.g We cleaned the room just now.
3.现在进行时: 主语+am/is/are doing
e.g We are cleaning the room now.
4.过去进行时: was/were doing
e.g We were cheaning the room at 5:00 yesterday afternoon.
5.现在完成时: have/has done
e.g.We have cleaned the room already.
6.过去完成时: had done
e.g We had cleaned the room before he arrived.
7.一般将来时: will do/
e.g We will clean the room tomorrow.
8.过去将来时: was/were to /would do
e.g He said he would clean the room next.

既然有人回答过了，那我就补充一下吧。
过去进行时：was/were+doing 表过去这个时段、时刻正在...
特别的，when引导的时间状语从句用一般过去式，主句用过去进行时；而
while相反
一般过去式指这个动作已经完成火这个动作经常发生；过去进行时指这个动作尚未完成本回答被网友采纳
