题目内容
5.I can't thank you too much for your kindness because without your help I have won the first prize in the speech contest.( )A. | can't | B. | shouldn't | C. | might not | D. | couldn't |
分析 对你的好心我感激不尽,因为没有你的帮助,我不可能在演讲比赛中得第一.
解答 答案:D 句意表达的是与事实相反的假设,要用虚拟语气;without your help相当于条件句if you hadn't helped me;对过去事实的相反假设,主语中要用情态动词加完成时态;shouldn't不应该,couldn't不可能.故选D.
点评 虚拟语气是表示与事实相反的假设,构成方式有:对现在或将来,条件句中用一般过去时态,主语用情态动词加动词原形;对过去,条件句中用过去完成时态,主语用情态动词加完成时态.学习时,要牢记构成方式.
