Step 3 Grammar
情态动词本身有一定的词义，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。情态动词无人称和数的变化，情态动词后面接的动词需要原形，否定式是在情态动词后面加nt,当我们想表达可能发生某事以及可能做某事时，可以用may / might表示。例如：
It’s cludy t, s it might snw.
也是阴天，所以有可能会下雪。
Bring a map because yu may want t travel arund.
带张地图，因为你可能想四处走走。
There may be a few shwers, s bring an umbrella with yu.
可能会有阵雨，所以随身带把伞吧。
might与may没有太大的区别，形式上might是may的过去式，但在表示将来的可能情况时，might表示的可能性比may表示的可能性还要小。例如:
Take yur swimwear because yu might want t g swimming in the sea.
带上游泳衣吧，说不定你想要到海里游泳呢。
英语中表示可能的方式有许多，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 pssible t d sth. .., It is pssible that…, 主语 + will prbably / pssibly + v.等。例如:
Is it pssible t visit Alaska in December?
十二月去阿拉斯加游览有可能吗？
It is pssible that it’ll be snwy in the night.
晚上有可能会下雪.
It’ll prbably be cld and wet
天气很可能会又湿又冷。
prbably表示“很可能”，所以表示的可能性要比pssible 大。
