Question

【题目】Her sister __________ in that school for two years before she went there as well.

A.has studiedB.was studyingC.has been studyingD.had studied

Answer 1

【答案】D

【解析】

句意：在她也去那所学校之前，她的姐姐已经在那里学习了两年。

考查时态辨析。根据从句“before she went there as well”可知此处讲的是在过去某一时间点前发生的事情；再由主句中时间状语“foe two years”可知要用完成时。由此可知此处要用过去完成时，其结构是had done。故选D。
