这要看B 的回答了,B说待两周,他即将去访问一些上海的学校,说明B现在还是在上海.所以是进行中的时期,要用进行时.
如果要使用A选项,双方对话应该是这样.
A:How long did you stay in shanghai?
B:Two week.I went to visit some schools in shanghai.
如果用C,have you stayed 双方对话应该是这样.
A:How long have you stayed in shanghai?
B:For two week.I went to visit some schools in shanghai
所以要注意句子的语境了，很重要的。你看下面。going to visit some schools in shanghai.--这句用进行时，所以按上句话表示现在还住在那里。是正在进行的时态，B do you stay C have you stay 都是平常语气的时态，兄弟，有时候用用排除法也是个不错的选择。
由题意得，这是问的将来的事情
所以A是错误的，B也是错误的，C还是错误的，只能选D，将来时。
do是一般时，have done 是现在完成时，在此也是不对的。
C
