Summary 1
情态动词
1.含 义
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。
2.特 征
情态动词无人称和数的变化,情态动词后面接的动词需用原形,
否定式是在情态动词后面加 not。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。
Summary 2
情态动词 may / might
1.区 别
might 是 may 的过去式，但表示可能性时没有很大区别，只是表示一般将来的可能性时，might 比 may 的可能性要小。所以might表示较多的怀疑，更加不肯定，语气更委婉。
【注意】
might常作may的替换词,既可表示现在时间,也可表示将来时间。
e.g. They may/might have a lot of work to do.
Peter may come with us tonight, but he isn't very sure yet.
I might go to a concert tonight.
John might be at home now.
2.句式用法
may 和 might 均可用于肯定句和否定句中, 两者的否定形式,
均在后面直接加not。
e.g. He might not be at home this moment.
may/might 可以表示请求,可用于主语是第一人称的一般疑问句,
对 “May I.. ”
1) 这类问句作肯定回答时, 除了用Yes, you may.之外, 还有更温和的
回答方式: Yes, please. ;
2) 在作否定回答时,除了No,you may not.或No, you mustn't. 之外,
还有更有礼貌的回答方式: I am sorry./ I'd rather you didn't./
I am afraid not. /You'd better not.
Summary 3
表示可能的其他方式
表示可能的方式有很多，除使用情态动词may / might、
副词probably以外, 还可以使用maybe / perhaps和possibly 。
【注意】
perhaps和maybe指“或许”,其可能性大致为一半;
possibly仅指“也许” “有可能”, 其可能性低于一半。
maybe比perhaps更口语化, 且要用于句首；
perhaps可用于句末、句中、句首。
probably是副词,意思是“大概;或许;很可能” , 其可能性
超过一半。
(probably＞perhaps＝maybe＞possibly)
e.g. It is possible for you to catch the train.
e.g. It is possible that it'll be snowy.
e.g. We will probably leave on Sunday.
e.g. Maybe I will go with them.
e.g. Perhaps / Maybe he will succeed.
e.g. There's possibly something wrong with the machine.
It is possible to do sth.
做某事是可能的
It is possible+ that从句
主语 + will probably / possibly + v.
