问题描述：
Nick has been to Beijing.Really?When_he_there?A has been to B has been in C did go D did go to
怎么选,
答
C
when 相当于一个过去时间状语， 要和一般过去时连用
========如有疑问，马上追问！祝学习进步========
答
选D，选过去式
答
A
答
C
前面说Nick has been to Beijing，说明之前到过，后面问什么时候去的，这就应该是一般过去时态，排除A、B，there是个副词，前面不用介词to，排除D。
答
has been to 曾经到过Nick has been to Beijing. Nick曾经到过北京.那么后面应该是问他是什么时候去的,所以要用过去时所以是When did he go there?&nb...
答
选c
-Nick 已经在北京了
-真的吗？他什么时候去的？
/对过去发问 所以用一般过去式did，
而there是个副词，go后面接there时不用加介词to
不知道答案对不对 希望可以帮到你
答
我认为应该选 C
NICK已经到北京了，是真的吗？
他什么时候到的
问的是过去的某一时间点，而不是段时间，所以应该用一般过去式
there here home 等词前面不加介词
如go home
所以选C
