选择题
---Why can you speak English so fluently?
---Oh, I________ English in Shanghai International Studies University for four years.
A．studied
B． would study
C．was studying
D．had studied
答案
A.
题目分析：乙英语之所以说得流利，是因为在上海国际关系学院读过四年。在上海读书是过去的事情，用一般过去时。本题干扰最强的是D项。had done表示“过去的过去”。本题不表示“过去某个时间之前”在上海读过四年。故答案为A.
