情态动词can的用法
can是一个常见的情态动词，表示说话人的语气或情态，基本意思是“能; 会”。它没有人称和数的变化，在句子中不能单独作谓语，其后必须跟实义动词原形。can的否定形式为can not/can’t/can not；过去式为could，其过去否定形式为could not/couldn't。
情态动词can有以下常见用法：
1. 表示能力
情态动词can一般指体力、知识、技能等方面的能力，即“能够；会”。
我哥哥会游泳，但是我不会。
My brother can swim but I can’t.
2.表示许可
多用在口语中，表示请求或允许，意为“可以；能够”等。用于疑问句中用来提出要求，用于否定句中表示不允许。
我可以用你的钢笔吗？
Can I use your pen
3.表示推测
情态动词can表示推测时，常用于否定句或疑问句，意为“（不）可能”。用于肯定句中表示理论上的可能性，意为“有时会”。
这里的春天有时可能会非常冷。
It can be very cold here in spring.
4.表示邀请
情态动词can除了表示能力、许可或猜测之外，还可以表示邀请；could较can更礼貌、委婉。情态动词can表示邀请时的用法如下：
当用情态动词can发出邀请时，用一般疑问句
Can+主语+动词原形+其他？
你能来参加我的聚会吗？
Can you come to my party
情态动词有：may/might, can/could, must, have to, shall/ should, will/would, ought to, need, dare...
1.不能独立作谓语，只能和动词原形一起构成谓语，表示说话人的语气和情态。
2. 没有人称和数的变化。 (have to除外)
3. 否定形式：在其之后加not (have to除外)。
　疑问形式：情态动词提到主语之前(have to 除外)。
情态动词
情态动词have to 与 must的用法
have to的意思是“必须、不得不”, 往往强调由于客观
原因而必须做某事。have to 后接动词原形；have to有人称、数
和时态的变化, 其第三人称单数形式为has to, 其疑问形式和否定
形式要借助于助动词do或does来完成。
Summary 4
We have to look after our sister at home.
我们不得不在家照顾我们的妹妹。
Does he have to get up early tomorrow morning
明天早上他必须早起吗？
have to 与 must
二者都有“必须”之意，但 have to 表示“客观上的需要”，有人称和时态的变化，否定形式为 don’t / doesn’t / didn’t have to (没必要)；must 表示“主观上的要求”，无人称和时态的变化，否定回答一般用 needn’t 或 don’t have to (不必)。must 否定形式为mustn’t，表禁止，意为“一定不要，千万别；不许”。
We have to wear warm clothes in winter.
冬天我们不得不穿上暖和的衣服。(客观需要)

看电视前我必须先完成作业。(主观要求)

—Must I be home before eight o’clock
8点之前我必须回家吗？
—Yes, you must. / No, you needn’t. / No, you don’t have to.
是的，必须回家。/不，不必。
might的用法
might 为情态动词，意为“可能”，might 表示推测时，不表示时态，只是可能性比may 小。
e.g.She might go to the movies, but I’m not sure.
