Question

【题目】— Do you think it wise for Chinese mothers to try to do everything for their children?
— No, that's exactly _____ the problem lies.
A.where
B.when
C.in which
D.what

Answer 1

【答案】A
【解析】考查表语从句。句意：--你认为中国的妈妈尽量为孩子做一切是明智的吗？--不，那就是她们错误所在。Is后面是表语从句，表语从句中不缺主宾表，所以不能用what，when什么时候，how怎么，不符合句意，从句缺地点状语，所以选A。
