1.i have been there before.2.i had been there before.
句1的用法正确么我之前去过那里可是现在并不在那里不是应该过去完成时么因为是在过去的时间去过那为什么还会有have been there before 什么区别

现在完成时立足现在过去完成时立足过去
I had been there before i came to China
再问：你是说过去完成时不能单独存在么？那如果是虚拟语气 If only i had been there. 为什么不是have been呢
再答：虚拟语气中凡是与过去事实相反的都是 had done 没有have done 的

I had been there before Because I never have been there before. they have been there before.so have i they have been there b I never there before.A.have;been to B.have;been C.have;gone I never been there before=I haven't been there before? I've been there before 还是I've been to there before? I have never been there before.这个句子中的before能否改成ago We had never been there before have been I have been a doctor before.I had been a doctor be I have been there 一首歌 HELP I ...again i have been there anytimes before hurt m he must have been there before-----
