题目内容
17.The train is to start soon and Mike hasn't arrived.What ______ have happened to him?( )A. | may | B. | might | C. | can | D. | should |
分析 火车很快就要发车了,迈克还没来.他可能发生了什么事呢?
解答 答案:C
分析句意可知,在应该到达火车站赶火车的时候,迈克没来;从而可推测出:迈克可能是发生了什么事;因此此处表示对事情发生的可能性比较大的推测;以上各选项都可以表示推测,只是相对于C来说,A.B.表示的可能性要小一些;D.表示的可能性最大:"按道理说应该会,想必会,一定会";但是由于火车毕竟还没有开走,迈克还有时间赶上火车;因此此处并不表示会有绝对的把握;故排除A.B.D;由于C.表示理论上的可能性(即从理论上分析是可能的,但实际未必会发生),故选C.
点评 本题考查了情态动词表示推测的用法;首先应根据句意,正确判断出空缺处所表示的可能性的大小;其次应熟练掌握各情态动词表示推测时的意义及用法区别;另外,还应掌握它们表示的可能性由弱到强的顺序:might,may,could,can,should等.
