have been 和 had been的区别

Question

分别在什么情况下使用呢

Answer 1

一楼说的对，have been 用在现在完成时态中，如：
I have been here for ten years.
They have been to Shanghai for a long time.

had been 用于过去完成时中。如：
I had been to XI'an before I went to Beijing.
在我去北京之前我去过西安。

希望能帮到你，祝更上一层楼O(∩_∩)O

Answer 2

丹霞游 对于这两个结构的笼统差别说的对
补充：
比如，你想说“我去过那儿”：I've been there before.
但如果是以前某个时间说的，就不一样了，
如：去年他告诉我说他去过那儿：He told me last year he had been there.

Answer 3

区别在于时态。前者是现在完成时，后者是过去完成时

Answer 4

前者是现在完成时，后者是过去完成时。
