表对将来事情的推测,语气非常肯定,译为“一定……”.can/could
表推测时一般用于否定句或疑问句,也是对现在或过去的事情进行推
测,但could偶尔可用于肯定推测.may/might表推测时一般用于肯定句
或否定句,可对现在、过去或将来的事情进行推测,语气不很肯定,
译为“可能……”.

情态动词can的用法及例句
情态动词有四类：
①只做情态动词：must,can(could),may(might),ought to
②可做情态动词又可做实义动词：need,dare
③可做情态动词又可做助动词：shall(should),will(would)
④具有情态动词特征：have(had) to,used to
用法
首先它是动词,而且不同于行为动词,行为动词表示的是可以通过行为来表达的动作（如写,读,跑）,而情态动词只是表达的一种想法（如能,也许,敢）.
用法是：情态动词+行为动词原形
例句：I can read this sentence in English.
我能用英语读这句话.
情态动词是一种本身有一定的词义,表示说话人的情绪,态度或语气的动词,但不能单独作谓语, 只能和其他动词原形构成谓语.
We can be there on time tomorrow.我们明天能按时去那儿.
May I have your name? 我能知道你的名字吗?
Shall we begin now?我们现在就开始吗?
You must obey the school rules.你必须遵守校规.
情态动词数量不多,但用途广泛,主要有下列:
can (could), may (might), must, need, ought to, dare (dared), shall (should), will (would),have (to) ,had better.
