when have you been there?这句话语法哪里错了?
为什么 因为when表示时间状语 所以不能用？

when have you been there?这句话语法哪里错了?为什么 因为when表示时间状语 所以不能用？
when 后应接具体动作,用于一般现在时、一般过去时、一般将来时等.如 when did you arrive there?
而 “have … been”则问过程、状态,是完成时的标志.如：
Have you ever been there?
How long have you been in the town?
这句话错将两种时态用词“when ”“have been”混用了.

我来试着帮你解剖一下。when 和have冲突了！句子分解就成了：when you been there?/Have you been there?可以改为 Have you been there，and when?

how long have you been there
when did you get there
第一句是你在那里多长时间了
第二句是你什么时候去那里的
