情态动词主要有：may / might, can / culd, shall / shuld, have t, must, 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)
2. 情态动词Can的常见用法：
(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”。如：My brther can swim but I can’t. 哥哥会游泳，但是我不会。(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。如：Can I use yur pen? 我可以用你的钢笔吗？
(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”。如： It can be very cld here in spring. 这里的春天有时可能会非常冷。
(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；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？如：Can yu cme t my party? 你能来参加我的聚会吗？
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。如：Sure, I’d lve t. 当然，我很乐意。 Sure, I think he she will. 当然，我想她会的。Srry. I’m nt available. 对不起，我没有空。I’d lve t, but I’m afraid I can’t. 我很乐意去，但是恐怕我不能去。
3. can 与 may
(1) 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）。如：Yu may / can sit here.The pliceman says yu can’t park here.(2) May / Can I…? 表示征询对方许可。Can yu…? 表示请求。— May I use yur phne? — N, yu can’t. / N, yu mustn’t.
(3) 都可表示“可能性”：① 肯定句 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)
② 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)③ 疑问句 Can this news be true? ( = Culd) ≠ May this news be true?
4. have t 的用法
(1) 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 (has) t 后面要用动词原形。当主语为第三人称单数时用 has t，当句子是过去时用 had t。如：He has t wrk n Sunday. 他不得不在周日工作。(2) have t 的否定句句型：主语 + dn’t / didn’t / desn’t / wn’t + have t + 动词原形。如：Yu dn’t have t walk s fast. 你不必走那么快。
(3) have t 的疑问句句型：D / Des / Did / Will + 主语 + have t + 动词原形。如：— Did he have t ask the questin? —他非要问那个问题吗？— Yes, he did. —是的。— N, he didn’t (have t). —不。
