past tense after *have*

[ahmin92]

Hi, it's me again :-D

my question is..
is it a must to put a past tense after the word *have and haven't* ?

like...
it has stopped.
it hasn't stopped running.
I have stopped smoking.
I haven't stopped smoking.
My period haven't stopped.

and... an addition
did she give/gives you some pills??
my answer is give. I don't know why but i think it's kinda weird if use gives. can anyone explain why ??
I would use give if the sentence ended with question mark whereas i will use gives if it ended with full mark.
example. she gives you a pencil. Am I using it correctly?

Your English seems to be slipping back. Three months ago you knew what a past participle was.

You think it's weird because it's wrong. That would be my explanation.
I would use 'give' if the sentence ended with question mark whereas i will use gives if it ended with full mark.
That's a strange way of looking at it. If it's a question with "did" in it, you use "give". Naturally, that sentence would end with a question mark.
example. she gives you a pencil. Am I using it correctly?

No, you're not. The reason "gives" is wrong in "Did she give you some pills?" is that, if the sentence contains "do" or "did", the main verb is in the bare infinitive. "Did give".
"She did give you some pills" also uses 'give'.

If you are using the present perfect tense, that is formed with the appropriate form of "have" plus the past participle.
Your sentences are correct. But they are not in the past tense.
