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”。
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。
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”。
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。情态动词can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？
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。
Sure, I'd lve t.当然,我很乐意。Sure, I think he/she/they will.当然,我想他/她/他们会的。
Srry. I'm nt available.对不起,我没有空。
I'd lve t, but I'm afraid I can't.
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)。
1. can/may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 smke 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. Reed 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” 肯定句
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?
2. can/be able t　(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?
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。 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或des来完成。
We have t lk after ur sister at hme.我们不得不在家照顾我们的妹妹。Des he have t get up early tmrrw mrning? 明天早上他必须早起吗？I dn’t have t stay at hme tday.今天我不必呆在家里。
4. 情态动词“have t”与其他的情态动词如“can”, “may” “must” 和 “shuld” 不同。 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.
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。 我们以can为例: Can he g with us? 他能和我们一起去吗？ He can’t g with us. 他不能和我们一起去。 而“have t”要加助动词d , des或did才可能完成其 疑问句、否定句。
5. must/have t must 表示主观“必须”；have t表示客观客观需要， 即“不得不” 。 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.
