— Tom, could you go to the supermarket with me?
— I’d like to, but my homework ______ and I have to hand it in tomorrow.
A.wasn’t finishedB.won’t be finished
C.hasn’t been finished D.hadn’t been finished
C

试题分析:考查时态。本题主要考查的是现在完成时的用法,现在完成时表示过去发生的事情对现在的影响,或者过去发生的事情延续到现在;而一般过去时只表示过去发生过某件事情,不表示对现在的影响。句意:—Tom,你能和我一起去超市吗?—我想去的,但是我的家庭作业还没有完成,我明天就要交了。这里表示过去发生的事情对现在的影响,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。
