选择题
---Where is your grandpa?
---He _________ Canada and __________ Toronto for a month.
A．has been to, has been in
B．has gone to, has been in
C．has been in, has been to
D．has gone to, has been to
答案
答案：B
题目分析：句意:--你的祖父在哪里？--他去加拿大了，他要在那里停留一个月。has been to表示去过某地，但是现在已经回来了；has gone to表示去了某地还没有回来；has been in表示在某地停留，后面可以跟时间段。根据for a month可知第二空应该用has been in，根据句意故选B。
