15．Which of the following is WRONG?A. Your car is good except for the colour.B. The film has begun for twenty minutes.C. I have kept the book for two days.D. What's the difference between the two tricks?【答案】 B【解析】【分析】句意：下面哪一个是错误的？A选项意为：你的汽车除了颜色之外其他都很好；B选项意为：这场电影已经开始二十分钟了。
这个句子是错误的，begun的原形是begin，意思是开始，是瞬间性动词，不能和一段时间连用；C选项意为：我借这本书已经两天了，这个句子是对的，keep是持续性动词；D选项意为：这两个把戏之间的区别是什么？故应选B。
【点评】考查句子结构。
掌握短暂性动词不能与时间段连用。
