题型:不详难度:来源:
Mountain climbing ______ be really dangerous at times even though it is challenging and exciting in general.
A.canB.shouldC.shallD.must

答案
A
解析

试题分析:在平时的学习中既要注意情态动词的基本含义,也要注意情态动词的特殊意义,如must偏偏,非得;should竟然;mustn’t禁止,千万不能;等等。情态动词Shall用于所有人称,表示命令,警告,允诺;以及法律规定中要做的事情。情态动词can能够,可能;should应该;shall将要;must一定,必须;本句考察的是情态动词can的一个特殊用法“有时候会…”;句义:即使登山总的说来很有挑战性也很让人兴奋,但是有时候它也很危险。故A正确。
