Question

【题目】— You seem to be familiar with the school campus.

— I ______ here for three years. It’s great to be back.

A. have taught B. taught C. had taught D. teach

Answer 1

【答案】B

【解析】考查时态。句意：——你似乎对这个校园很熟悉。——我在这里教过3年学。回来真是太好了。根据第一句和It’s great to be back.可推知，“在这里教过3年学”是过去发生的事情，现在不教了，故用一般过去时态，答案为B。
