题目内容
4.Although Lily is usually easy-going,she__________ be sometimes quite annoying.( )A. | must | B. | need | C. | can | D. | should |
分析 虽然Lily通常容易相处,但是有的时候也会很恼人.
解答 答案是C.本题考查表示推测的情态动词的用法. 动词原形be前需要的是情态动词,need作为情态动词不能出现在肯定句中,首先排除B;情态动词must表示推测语气非常肯定,只能出现在肯定句中,表示有客观依据的推测"准是,一定是".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…";can表示推测往往出现在否定句或疑问句中;在肯定句中出现时表示"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.本题中由上文"usually easy-going通常容易相处",推测"annoying(恼人的)"是与一般情况不符,所以答案是C.
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.
