Question

Tim ____since he lost his job three weeks ago.

A．had been unemployed	B．was unemployed
C．has been unemployed	D．has unemployed

Answer 1

C

试题分析：句意：Tim自从三周前丢了工作，他再也没有找到。这里Tim与unemploy之间是被动关系，故排除D，又因为since自从，常与现在完成时连用，故选C。
点评：本题难度适中。动词时态与语态在一起考查更增加了试题的难度，但是又与一定的语境结合一起增加了试题的难度，有的考生时态的用法背的很熟，但在不同的语境下，就做不对了，提醒考生一定要会分析理解语境。
即学即练：John and I ________ friends for eight years. We first got to know each other at a Christmas party. But we _______ each other a couple of times before that.
A. had been; have seen       B. have been; have seen
C. had been; had seen        D. have been; had seen
解析：D。句意：我和约翰成为朋友已经8年了。我们首次认识是在一次圣诞节聚会上。可是在这之前我们相互见过几次面。根据句意选D。
