Is this factory__you visit a few months ago? yes,but it isn't___ it used to be.

原句可改成this factory is ____you visit a few months ago。 yes,but it isn't___ it used to be.

前一句是表语从句，is 后面少了先行词 所以用the one 代替
后一句也是表语从句，少了宾语 用WHAT

A

C

前句是从句要由that引导
后面是代词。指那一个

选择 c

that 是定语从句重的连接词

the one 是替代词

替代前面的the factory

这家工厂就是你几个月前排放过的吗？
是的，但是它已经不是以前的那家工厂了

C

The first answer is very ridiculous.
The correct anser is C
