'Have pp

I've heard it

I've seen it

I've done it

I've said it

I've met him

I've been here

I have taught her before 그녀를 가르친 적이 있다

I've never done it 해본적 없어

I've never said it 말한적 없어

I've never been there before 가본적 없어

Have you been there before?

It has been there before! 와본적 있어

I've lived here for/since ~ 10 years 10년동안 쭉 여기서 살고 있어

I've worked here 

I've known it since 

We've been married 

We've been happy

I've heard it before

I've watched it before

I've done it before

I've said it before

He's kissed her before 그는 그녀에게 키스한적이 있어

I've been there before

I've called him before

He's met her before

They haven't seen her before

They haven' eaten it before

They haven't talked to him before

Have you used it before?

Have you been there before?

Have you called him before?

Has he kissed you before?

Has he met her before?

Have they talked to him before?

I've had it
