题目内容
3.-Hi,Johnson,any idea where Susan is?-It's class time,so she _____ in the classroom now.( )
A. | can be | B. | must have been | C. | might have been | D. | should be |
分析 --嘿,Johnson,知道Susan在哪里吗?
--现在是上课时间,因此她应该在教室里.
解答 答案是D.本题考查表示推测的情态动词的用法.A项can出现在肯定句中表示"客观上、理论上的可能性",常常暗示可能性很小,与一般情况不相符.B项must have done表示推测,表示"肯定已经…";C项might have done 既可以表示推测"也许已经…";D项 should表示推测时往往表示"按照常理常规的推测",表示"按照道理应该…";B和C都是对过去的或已经发生是事件的推测;A和D都是对现在的状态的推测;根据句意可知,现在是上课时间,因此按照常理推测她现在应该在教室里.所以答案是D.
点评 要在正确理解情态动词的基本含义的基础上,整体理解语境中的情感态度,做出合理的判断
