一定要准确
越完整越好
有参考资料更好
英语高手帮忙了
举个例子
现在进行时 ：（am is are）be +doing

I do my homework everyday.一般现在时
I am doing my homework now.现在进行时
I have done my homework.现在完成时
I did my homework yesterday.一般过去时
I was doing my homework (that time).过去进行时
I had done my homework(before I went to school).过去完成时

还有几种我忘了……

I'm doing my homework.
I do my homework every day.
I have done my homework.
I had done my homework when they arrived there.
I did my homework yesterday.
I was doing my homework then.
I have been doing my homework from then on.
