题目：
I don’t remember how many years ago ____ I last showed you around the old campus.
A．it was that
B．was it that
C．it was which
D．was it when
答案：
答案：A
题目分析： 本题考查强调句和宾语从句的语序。"it was … that"是强调句的标志词，句中的宾语从句how many years ago it was that...由强调句it was many years ago that...转化而来。句意：我不知道我上次是多少年前带你参观老校园的。故A正确。
