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 nt/can’t/cannt；过去式为culd，其过去否定形式为culd nt/culdn’t。
情态动词Can有以下常见用法：
情态动词can一般指体力、知识、技能等方面的能力，即“能够；会”。
例：我哥哥会游泳，但是我不会。
My brther can swim but I can’t.
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。
例：我可以用你的钢笔吗？
Can I use yur pen?
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”。
例：这里的春天有时可能会非常冷。
It can be very cld here in spring.
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；culd较can更礼貌、委婉。表示邀请时的用法如下：
（1）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？
例：你能来参加我的聚会吗？
Can yu cme t my party?
（2）当用情态动词can发出邀请时，其回答分 为两类。一类表示接受邀请，另一类表示 拒绝邀请。
Srry. I’m nt available.
I’d lve t, but I’m afraid I can’t.
例：当然，我很乐意。
Sure, I think he/she/they will.
当然，我想他/她/他们会的。
我很乐意去，但是恐怕我不能去。
情态动词有：may/might, can/culd, must, have t, shall/shuld, will/wuld, ught t, need, dare, used t
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 t除外)3. 否定形式：在其之后加nt (have t除外)。　疑问形式：情态动词提到主语之前 (have t 除外)。
都可表示“许可” 。may用于较正式、 客气的场合，而can比较随便（口语）。 Yu may/can sit here. The pliceman says yu can’t park here.
(2) May/Can I/we…? 表示征询对方许可。 Can yu…? 表示请求。 — May I use yur phne? — Yes, yu can. / Yes, please. N, yu can’t. / N, yu mustn’t.
Mr. Read lks pale. He may be ill. (事实上的可能)Mr. Read is in pr health. He can be ill at any time. (逻辑、理论上的可能)
(3) 都可表示“可能性”
否定句This news may nt be true. (也许不 = might nt )This news can’t be true. (不可能 = culdn’t)疑问句Can this news be true?(=Culd)≠May this news be true?
(1) can = am/is/are able t = shall/will be able t① N ne can d it. = N ne is able t d it. ② Can yu cme tnight? =Will yu be able t cme tnight?
2. can/be able t　
have t 后接动词原形；have t有人称、数和时态的变化, 其第三人称单数形式为has t，其疑问形式和否定形式要借助于助动词d, des或did来完成。
3. have t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。
我们不得不在家照顾我们的妹妹。We have t lk after ur sister at hme.明天早上他必须早起吗？Des he have t get up early tmrrw mrning? 今天我不必呆在家里。I dn’t have t stay at hme tday.
(1) 这4个情态动词没有人称的变化，而have t有, 它的第三人称单数为“has t” 如： He shuld study hard. He has t study hard.
4. 情态动词“have t”与其他的情态动词如 “can”, “may” “must” 和 “shuld” 不同。
例: 他能和我们一起去吗？ 他不能和我们一起去。
(2) 这4个情态动词在一般疑问句中将它们放在 句首，在否定句中直接在他们后边加nt即可。
Can he g with us?
He can’t g with us.
而“have t”要加助动词d , des或did才可能完成其疑问句、否定句。
I dn’t like this TV set. I must buy a new ne.This TV set desn’t wrk. We have t buy a new ne.
5. must/have t
must表示主观“必须”；have t表示客观需要，即“不得不” 。
