@fresco,
Thanks a lot for your pointing out the error with the sharp sense.
It helped pointing out the error
By the way,
Someone(I don't know him) and I have been debating hotly on the dialogue.
Then,
he insist that the present perfect tense in the first sentence is used for 'Life Experience' in the uses of present perfect tense.
But I insist it is used for A finished action with a result in the present (focus on result)
like the following Ex.)
I've lost my keys (so I can't get into my house).
She's hurt her leg (so she can't play tennis today).
They've missed the bus (so they will be late).
I've cooked dinner (so you should come and eat).
~~~~~~~~~
So I think like the following.
"A: I think She has had plastic surgery"(so I think She doesn't look like a natural beauty in my eyes).
of course, I think the sentence is used to present 'Experience(plastic surgery)' too. But I think the focus is not on the experience.
I assume The focus of the context is on 'Result' as "A finished action with a result in the present"
"I think Sarah has had plastic surgery"
Who is correct between he and me, debating on The dialogue?
