1.情态动词+动词原形，表示对现在某动作或状态的推测，比如must do，can't be等。
例：It can't be true.这不可能是真的。

3.情态动词+have done，表示对过去行为或动作的推测，比如must have done等。
例：He must have misunderstood me.他一定是误解了我。
易混点：can’t 和 mustn’t
1. can’t 根据其基本用法可译为：
（1）不会。如：I can’t speak English . 我不会说英语。
（2）不能。如：We can’t do it now because it’s too dark.天太黑了，我们现在干不了。
（3）否定句中表示推测,不可能，如：The man can’t be our teacher because he is younger than our teacher.那个人不可能是咱们老师，他年轻得多。 2. mustn’t 意为禁止、不许， 用来表达命令，表示强烈的语气。 如：You mustn’t play football in the street. It’s too dangerous.你不可以在街上踢足球，太危险了。
It must belong to Carla.它一定属于卡拉。
belong to意为“属于”,其主语通常是物,它不能用于进行时和被动语
