present perfect tense

Thanks for your comment for the last message.

Still I have a question and need more of your help.^^

As I know, the present perfect tense refer to something which affects to the present situation. In that sense, I still don't understand how the present perfect tense can be used in a context which refer to the future behavior. (Simple present tense can refer to the future, I know but the present perfect tense also can refer to the fututure?)

For your memory, I will write the sentence here again.

Thanks a lot!

Larry will call Sue after he has spoken to his mom.

The present perfect part of that sentence "he has spoken to his mom" does not have future reference. The future reference is provided by "will call" and "after". The time when "he has spoken to his mom" is the base time. Things that happen after the base time are future with respect to the base time.

First of all, there is no future tense, but merely means of expressing future time.
1- Shall/will + inf
2- Be going to+inf
3-Progressive aspect, present
4-Simple aspect. present
5-Shall/will + progressive
6-Be+about to +inf
7-Be to+inf

The present perfect tense is never used to refer to the future time

In this sentense, the present perfect does not refer to the future but to the past. Notice this structure:
After speaking to his mother, Larry will call Sue.

Larry will call Sue after he has spoken to his mom.

Can we say "Larry will call Sue after he speaks to his mom?"

Thanks! :o

Yes, you can say that.
But you'd better say:
Larry will call Sue after speaking to his mom
