Question

---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

Answer 1

A.

解析试题分析：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.
考点：动词时态的用法。
