题目
题型:不详难度:来源:
Thomas _____ a soldier, for he is much too short.
A.needn’t beB. should beC.may beD.can’t be

答案
D
解析

试题分析:句意:托马斯不可能是一名士兵,因为他太矮了。can’t be不可能,表示强烈的否定推测,故选D
点评:本题是高考必考考点,一定要牢记句型意思。must表示强烈的肯定推测,can’t表示强烈的否定推测,can, could表达推测时,一般用于疑问句和否定句中;can用于肯定句中表推测时,表示理论上的可能性。另外情态动词与完成时态连用的用法也是重点,如must have done过去肯定做了某事。should have done 本应该做而实际未做; can’t have done 过去不可能做了某;shouldn’t have done 本不应该做而实际做了; need have done 本有必要做某事;needn’t have done 本没有必要做某事,注意没有 mustn’t have done的形式
