Step 3 Grammar
情态动词本身有一定的词义, 但不能单独作谓语, 需要和其他动词（原形）一起构成谓语, 为谓语动词增添情态色彩, 表示说话人对有关行为或事物的态度和看法, 认为其可能、应该或必要等。我们学习过的 can 和 may 都属于这类词。
may/might可以用来表示推测，意为“可能”。它们的否定形式分别是may not和might not。
e.g. I think Mary may be in the library.
That man may not be Jack’s uncle.
How long might the travel take?
Betty might not go to work next week.
注: may和might在表示将来的可能情况时, might比may表示的可能性要小一些。
英语中表示可能的方式有很多, 除使用情态动词may/might以外, 还可以通过will以及表示“可能”的形容词和副词表达, 常用的有：
It is possible to do sth. ...
It is possible that …
主语＋will probably/ probably ＋v. 等
e.g. It is possible that it’ll be snowy in the night.
晚上有可能会下雪。
It’ll probably be cold and wet.
天气很可能会又湿又冷。
注: probably 表示“很可能”，所以表示的可能性要比 possible 大。
