where have you___?the teacher wants you to assist her.A gone B gone to C been D been to

问题描述:

where have you___?the teacher wants you to assist her.A gone B gone to C been D been to

have been/gone to 这个to不可省略,所以排除AC
have been to 去了某地(现在不在那个地方)
have gone to 去了某地还没回来
根据第二句话“老师想叫你来帮助她”,推测出是去了某地还没回来,所以选B
请指出,希望能和你一起探讨~
