Question

It was in the school ( ) Mr.Smith taught ( ) we studied.

It was in the school ( ) Mr.Smith taught ( ) we studied.
A.where B.that C.when D.what
答案是：AB
为什么？

Answer 1

首先，这是个“It + be + 强调部分+that +其他部分”结构的强调句型，所以，第二个空填that。
其次，mr smith taught为定语从句，修饰the school,而先行词在从句中作地点状语，所以用Where

Answer 2

分析句子结构就明白了：第一个空是定语从句的引导词，因为先行词是地点（school）作状语，故用where，再看第二空，是一个强调句（即整句话）：It was ... that....“我们学习的地方正是Mr. Smith教书的学校”,故答案是对的
