—Can I help you,sir?
—Yes,I bought this radio here yesterday,but it _______ .(NMET96)
A.didn't work B.won't work C.can't work D.doesn't work
答：楼主的题目由这道有争议的高考题改编而来.网上这题参考答案是D,但也有C的,说明了此题是有问题的.
其实,除了A外,BCD三个答案都通.有人为此写了论文：《由一道高考题引起的思考》作者：张满胜,可惜我看不全.
现在楼主的题却将“正确”答案D 的doesn't work 改成了isn't working,可能他的原“正确”答案是C吧?.想避免这个争议,但改编者的答案,我想就不会是D,因为It isn't working.只表示这收音机现在没在工作.没有开也可以说是这种状态.并不能说明它坏了.所以你说你选D选对了,我不认为你对了.
这对话的语境是很明显的：
营业员：需要我的帮助吗?
顾客：是的.我昨天在这里买了台收音机.可是现在不响了.（不知道怎么回事,昨天还响的,好好的.）

再问： 唔..老师这样子讲的........好奇怪
