Question

【题目】He an engineer since he from the university.

A. is; graduatesB. will be; graduates

C. has been; has graduatedD. has been; graduated

Answer 1

【答案】D

【解析】

句意：自从他从大学毕业以来他就一直是一个工程师。

is是；will be一般将来时；has been现在完成时；graduates毕业，一般现在时第三人称单数形式；has graduated现在完成时；graduated一般过去时。句中since引导的是时间状语从句，从句中用一般过去时，主句用现在完成时。故应选D。
