题目内容
Mountain climbing ______ be really dangerous at times even though it is challenging and exciting in general.
| A．can | B．should | C．shall | D．must |
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。
考点：考察情态动词用法
