1. I come to apologize.
2. What wind blows you here?
3. Bill says he is a good doctor.
4. He is long dead.
5. The story is set in the spring of 1934.
6. In that later she tells why she was up there.
I think they are all "present simple" sentences that express "simple past".
But I have recently met such a question:
--- Good morning, I ____ to see Miss Mary.
--- Oh, Good morning, I'm sorry, but she is not in.
C) had come
D) have come
The answer is D) <and A works too>; B) is not right.
I don't see what's the difference between
"I come to apologize." and "I come <wrong choice B> to see Miss Mary"
Could you please help me out?
Many thanks in advance.
