The machine _____ . It hasn’t worked for years and no one wants to repair it.
A.didn’t workB.wasn’t working
C.doesn’t workD.isn’t working
C

试题分析:考查时态。句意:那台机器坏了。它已经工作了很多年,没有人再想去修它了。说明经过多年的使用以后,现在这台机器坏了。故C正确。
点评:英语中的时态主要由动词的形式决定,因此在学习英语时态时,要注意分析动词形式及具体语境,想象在那个特定的时间动作所发生的背景,这个动作是经常性动作、一般性动作、进行性动作、完成性动作还是将要发生的动作。语态是动词的一种形式,表示主语和谓语动词之间的逻辑关系,被动语态表示主语是谓语动词所表示的动作的承受者。现在完成时的这一用法常用ever, never以及表示次数的词或短语作时间状语。
