Question

It was____my father worked_____i work now.

A.where that B.that where

Answer 1

A
这是一句强调句，强调的是从属连接词where引导的地点状语从句，意思是“我在我父亲曾经工作的地方工作。”把It was...that去掉后，剩下的部分仍然是完整的句子，即：
I work where my father worked.
希望我能帮助你解疑释惑。

Answer 2

选A
第一空表地点~~where
然后 where my father worked 等于 the place
要说 it was the place（先行词） that i worked now~~
