Question

This is the school ____I worked seven years ago. 　　 A.in which　 B. in that　　C.which D.that

Answer 1

答案选A
这是一个定语从句
所以从句是：I worked （in the school）seven years ago
school就用which 代替了，所以要加in which

追问

那如果是This is the school which i worked in seven years ago可以吗？

Answer 2

选A。
考查的定语从句，先找先行词，先行词是school，带到从句当中是I worked in the school seven years ago。school在从句中做介词宾语，介词提前，在介词后面指物只能用which，不能用that，所以选A。

Answer 3

c.

Answer 4

A
