for+时间段的句型句首要用什么时态?

现在完成时:

I have waited for a week before I saw you.

过去完成时:

I had starved for three days when I arrived there.

现在完成进行....完成时的就不说了

>>>I waited you in the park last night.

>>>I am waiting for you!

>>>I was waiting for you at nine o'clock.

>>>I will wait you in New York.

>>>Wait for me.

不过常见的还是完成时,和进行时

一般是完成时
