between "have" and "do" in a question tag

[kahhong]

helo~~!

teacher~ i tend to confuse when i use "have" and "do" in a question tag.

for an example:
have you seen my pen?
do you see my pen?

what is the differences between those two sentences?
how about past tense
for an example:
had you seen my pen?
did you see my pen?

i think that all from me.. glad to hear you soon...... thanks

Hello Kahhong,

Have you seen my pen? (right from the past, until now)
Do you see my pen? (right now)

Had you seen my pen? (.... before I found it?)
Did you see my pen? (...yesterday?)


Best wishes,
Dany
