只作情态动词的 can / culd, may / might, ught t, must可情态可实义的 need, dare 可情态可助动词的 shall / shuld, will / wuld相当于情态动词的 have t, used t
情态动词不能单独做谓语, 除ught和have外, 后面只能接不带t的不定式。 情态动词没有人称, 数的变化, 但有些情态动词, 如can、will也有一般式和过去式的变化。情态动词的“时态”形式并不是时间区别的主要标志, 不少情况下, 情态动词的现在式形式和过去式形式都可用来表示现在时间、过去时间和将来时间。
1) can的主要用法是： A. 表示体力或脑力的能力： e.g. The girl can dance very well. B. 表示说话的推测﹑事物的可能性等: e.g. Can the news be true? C. 在口语中, can可以表示请求或允许: e.g. Can I sit here?
can表示“能够”时与短语be able t同义，但can只用于一般现在时或过去时，而后者可用于各种时态。另外，can表示个人有某种能力，而be able t表示某人通过努力、克服困难做成某事，相当于succeed in ding sth.；叙述过去事实时，最好用was / were able t，因为culd只表示过去具有某种能力。
如：Can yu understand the different kinds f English these peple are using?Tw years later, he was able t speak very gd Chinese.
2) culd的主要用法是： A. culd 是can的过去式, 表示与过去有关的 能力和推测: e.g. We all knew that the yung man culdn’t be a dctr. B. culd可以代替can表示请求, 但语气较can 客气、委婉:
e.g. Culd yu lend me yur dictinary? Culd I use yur bike?3) can和culd接动词的完成形式，表示可能已经做某事。can用在否定和疑问句中，表示不相信、怀疑等态度。e.g. They can’t have gne ut because the light is still n.
以culd或wuld提问时，不能再以culd或wuld作答，而应该用can或will。如：—Culd I brrw yur dictinary?—Yes, f curse yu can.
culd与can都是情态动词，culd是can的过去式。二者都可用于表示请求，但是用法稍有不同。can 表示一般性的请求，语气随便，常用于熟人之间或长辈对晚辈，上级对下级的场合。e.g. Can yu tell us yur stry,Tny？ 托尼，你能给我们讲讲你的故事吗？
culd与can的区别
culd表示有礼貌的请求，语气委婉，常用于非熟人之间或晚辈对长辈，下级对上级的场合。比如： — Culd yu tell us if it snws in winter in Australia? — Sure. — 请告诉我们，澳大利亚冬天下雪吗?— 当然可以。
注意：1. 提出委婉的请求在回答中不可用culd。 A: Culd I have the televisin n? B: Yes, yu can. / N, yu can’t.2. 在否定、疑问句中表示推测或怀疑用culdn’t。 He culdn’t be a bad man. 他不大可能是坏人。
may和might表示允许或请求；表示没有把握的推测；may放在句首，表示祝愿。 May Gd bless yu! He might be at hme.注意: might 表示推测时，不表示时态，只是可能 性比may小。
have t和must
1. 两词都是“必须”的意思，have t 表示客观的需要，must 表示说话人主观上的看法，即主观的必要。My brther was very ill, s I had t call the dctr in the middle f the night.我弟弟病得很厉害，我只得半夜里把医生请来。(客观需做此事)He said that they must wrk hard. 他说他们必须努力工作。(主观上要做这件事)
2. have t 有人称、数、时态的变化，而must只有一种形式。但must 可用于间接引语中表示过去的必要或义务。He had t lk after his sister yesterday.
3. 在否定结构中: dn’t have t 表示 “不必”，mustn’t 表示“禁止”。Yu dn’t have t tell him abut it. 你不一定要把此事告诉他。Yu mustn’t tell him abut it. 你一定不要把这件事告诉他。
