Question

【题目】Three years and a half ________since I studied in the middle school.

A.have already pastB.has been passedC.has passed

Answer 1

【答案】C

【解析】

句意：自从我在中学学习三年半已经过去了。

考查动词时态。根据从句since I studied in the middle school.自从我在中学学习可知，主句应为现在完成时，“Three years and a half”作主语，助动词用has，pass的过去分词是passed，排除A；主语与pass之间不存在被动关系，排除B。故选C。
