He can't be at home, because I saw him board the flight to Beijing this morning.——Stephen,咱们一起拜访汤姆吧.——没必要这样做.他一定不在家,因为今天早晨我看见他登上了飞往北京的航班.2．may/might用于肯定句中可以用来表示不十分肯定的推测,意为“有可能”；用于否定句中也可以表示推测,may not意为“可能不”,表示一种不太确定的语气.The traffic is heavy these days. I might arrive a bit late, so could you save me a place?这些天交通很繁忙,我可能会来晚一点,请你帮我保留个位置好吗？3．must表示推测时只能用于肯定句中,意为“一定,必定”,表示十分肯定的语气(在疑问句中或否定句中要用can/could).—It's the office! So you must know eating is not allowed here.—Oh, sorry.——这是办公室！所以你一定知道这里不许吃东西.——噢,对不起.4．should用来表示推测时意为“应该”,即含有“按道理来说应当如此”的意思.There shouldn't be any difficulty about passing the road test since you have practiced a lotin the driving school.因为你在驾校训练了这么多,通过路考应该没什么困难.八、“情态动词＋have done”结构1．should/ought to＋have done,表示“过去本应该做而(实际)没有做的事情”,含有责备或遗憾的语气,意为“本应该……”.其否定形式为“should not/ought not to have＋done”,表示某种行为本不该发生但实际上发生了.I shouldn't have watched that movie—it'll give me horrible dreams.我本不应该看那部电影——它会令我做噩梦.You ought to have come to the party yesterday, but why didn't you come?昨天你本来应该参加聚会的,可是你为什么不来？2．must＋have done,用于肯定句,表示“过去一定做过某事”,表示一种很有把握的推测.注意,对过去发生的情况的否定推测常用“can't/couldn't＋have done”表示.—Ye Shiwen won two gold medals in London Olympic Games.—She must have gone through tough training.——叶诗文在伦敦奥运会获得了两枚金牌.——她肯定受到严格的训练.—Do you know where David is?
