题目内容
14.---He is talking excitedly about Chang'e-3with his friends.---He ______ the live broadcast of its successful landing on the moon last night.( )
A. | must have watched | B. | should have watched | ||
C. | must watch | D. | should watch |
分析 --他正在兴奋地和朋友谈论嫦娥3号.--他昨晚肯定看了它成功登陆月球的现场直播了.
解答 答案是A.本题考查情态动词表示推测的用法;must往往用在肯定句中表示有客观依据的推测;should表示按照常理、常规的推测.由"他正在兴奋地谈论"这样的客观依据推测他"肯定"看了现场直播,所以排除B和D;对过去的或已经发生的事件的说明用"情态动词+have done"的形式,由last night推断本题说明的是过去,所以排除B,答案选择A.
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.
