题目内容
9.--Could I play chess at the moment?--No,you _____.You haven't washed the dishes yet.( )
A. | couldn't | B. | needn't | C. | Shouldn't | D. | can't |
分析 --我这会儿可以玩一下象棋吗?
--不,你不能,你还没有洗盘子呢.
解答 答案:D.needn't不必;shouldn't不应该;can能,能够.Could是can的过去式,用于一般现在时态表示委婉的请求建议等语气.couldn't 是can′t的过去式和虚拟式.在实际应用中,could′t是can′t的礼貌用法,含有不情愿的意思,加上有虚拟的含义,语气较弱.表示否定时can't比couldn't的否定意味更重.根据句中的"You haven't washed the dishes yet",可知该空应该用can't,表示拒绝;故选D.
点评 情态动词的考查是初中英语考查的重点,平时学习中一定要熟记这些词的基本词义及用法上的不同,注意其用法及在句子中表达语气的不同,结合语境选择合适答案.
