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

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.

have been 后面加什么,have呢 in加时间段和after加时间段英语语法 ...would have been 后面加什么? 现在完成时have后什么时候后面加been? 完成时HAVE后面什么时候加BEEN have ever 为什么后面加been participate后面一定要加in吗 have been in是不是瞬间动词 Have/has been 后一定要加doing sth.吗? in加时间段后是不是不能用现在完成时?如：in 1980 have been in 和have gone to是不是一个意思? 在次数和时间词前面是不是要加for啊?还有阿,have gone/been to 后面能不能加一段时间呢?
