have been in 后面是不是一定要加时间段
Have you ever been in America?怎么回答啊?
Yes.I have been in America.对吗,是不是一定要加时间段

Answer 1

不对.回答应该是have been to America 或者 have been there,抑或直接是have
have been in 后面确实是要加一段时间状语的,比如：
How long have you been in China?
I have been in China for two years.或者
I have been in China since two years ago.
