is it in the factory____ you visited last week ____t this kind of car is made
A./...that
B.where...when
C.where...that
D./...where
选a,为什么不选d

Answer 1

解这种题是考你 定语从句 和 强调句的疑问形式的用法.还是要靠自己多练和自己分析的.
首先you visited last week 的visited后面缺宾语(factory).this kind of car is made后面缺状语（in the factory）.
而句子开头It is后面跟的是in the factory,所以知道这个强调句是跟this kind of car is made.所以再第二个空填that.
那么前一个空就是定语从句的连接词：which /that/不填.
最符合答案就是A.
