Is it in that factory "Red Flag" cars are produced?可以看成定语从句吗?为什么不能用where?Is it in that factory where "Red Flag" cars are produced?

问题描述:

Is it in that factory "Red Flag" cars are produced?
可以看成定语从句吗?为什么不能用where?
Is it in that factory where "Red Flag" cars are produced?

这是一个强调句式it is 。。。。that。。。。
换成疑问句式,where 不能引导这样的句子

本句应该是强调句,it is …that只不过用的是疑问句

可以 "Red Flag" cars are produced来修饰factory
但where是副词 不能充当的

这明显是一个强调句型的疑问句式
