A. | must | B. | should | C. | could | D. | might |
分析 --我今天早晨在街上遇见了你们老板.
--啊?你肯定是在开玩笑.他昨天乘飞机起欧洲了.
解答 答案是A.本题考查表示推测的情态动词的用法.情态动词must表示推测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…";could表示推测往往出现在否定句或疑问句中;might表示推测往往出现在肯定句或否定句中表示不太肯定是推测"也许";本题中由下文的客观依据"他昨天乘飞机飞往欧洲了",推测"你肯定在开玩笑",所以答案是A.
