4.They have got to know each other for ten years.

1.When did you went to the library?-Three hours ago.
2.It has been two hours since he has been here.
3.The girl has been asleep since 9 o'clock.
4.They have known each other for ten years.

1.When did you went to the library?-Three hours ago. 有ago就不能用现在完成时
2.It has been two hours since he has been here. 就是有since一定要用完成时嘛
3.The girl has been asleep since 9 o'clock.fall asleep是瞬间动词，这里只能用延续性动词
4.They have known each other for ten years同上
