情态动词 can 没有人称和数的变化， 否定形式是can’t， 过去式是could。

头的一般疑问句作肯定回答用“Yes, 主语 +can.”； 作否定回答用“No, 主语 + can’t.”
情态动词 can 的基本用法
2. can表示请求、 允许做某事时， 对于以它
开头的一般疑问句：
作肯定回答：Sure. /Yes, sure. /
Sure, I’d love to.
作否定回答：Sorry, I can’t. / I’m afraid not.
/ I’d love to, but …
— Can you come to my house next Monday

That man can’t be Mr. Li because he is in Paris now.
那个男人不可能是李老师， 因为他现在在巴黎呢。
3. can还可以表示推测， 常用于否定句。
情态动词might
情态动词might为情态动词may的过去式。
目前为止需要掌握的用法为：
一、表示请求时，两者可以互换，只不过might的语气较委婉。
e.g. May I come in
Might I come in
e.g. May I help you
Might I help you
二、表推测。此时might比may的语气更不确定，即可能性更小。
常见用法：
1）主语 + might + be +表语。（表示主语的状态可能是···）
e.g. You might not be right. 你或许不是正确的。
e.g. I can’t find my pen. It might be in my bag.我找不到我的笔了，它大概在我包包里吧。
e.g. I think she might be at home. 我想他大概在家吧。
2）might do (sth.) 也许会做···，可能要做····。
e.g. He might eat ice-cream. 他也许在吃冰淇淋吧。
e.g. It’s 6 p.m. He might come back soon. 六点了，他也许不久就会回来了。
3）might be doing (sth.) 也许正在做····，大概正在做···。
e.g. He might be swimming right now. 他现在也许正在游泳呢。
e.g. I think he might be doing his homework now. 我认为大概他现在正在做他的作业呢。
小知识：might have to的用法。
might have to do (sth.) 也许不得不做···，或许不得不做···。（可以理解为属于表推测中的第二种用法，用于表示对将来可能发生事情的推测）
e.g. I might have to go to the doctor tomorrow.
e.g. John might have to go to a movie with his friends in the afternoon.
