情态动词+ have done结构：
1.“must + have + 过去分词”表示对过去发生的事情或状态进行推测,语气比较坚定,通常只用于肯定句.如：It must have rained last night,for the ground is wet.
2.“can / could + have + 过去分词”表示对过去某种情况的怀疑或不确定.can和could一般用于否定句和疑问句,could的语气较can弱.如：He can't have finished the work so soon.
3.“may / might + have + 过去分词”表示对已发生的动作或存在的状态进行不肯定的推
测,might的语气比may弱一点.这种结构主要用于肯定句和否定句,疑问句改用can或could.如：They may not have known it beforehand.
4.“need + have + 过去分词”表示过去做了不必做或不需要做的事情,或过去做某事纯属多余.如：I needn't have bought so much wine—only five people came.
5.“should / ought to + have + 过去分词”表示过去本该做某事但没做,其否定式表示过去不该做某事但做了,这种句式含有不满或责备之意,ought to的语气比should强一些.如：
You ought to / should have studied harder.你本应该更努力学习的.（但没有）
He oughtn't to / shouldn't have done that.他本来就不该做那件事.（可是做了）
6.“would ＋ have ＋过去分词”表示对过去的某种情况进行猜测,或本来要做某事却因某种原因未做成,通常用来说明某一情况,但不像用should或ought to那样含有责备之意.如：
I guess the poet would have been about twenty when she wrote her first poem.
Another worker wouldn't have acted like that.

情态动词 一、概述 情态动词表示说话人对某一动作或状态的态度，认为“可能、应当、必要”等等，但本身意义不完全，不能单独作谓语，必须和其他动词一起构成谓语。除ought, used, have后跟不定式外，其他情态动词一律跟动词原形。情态动词主要有：can/could, may/might, must, ought to, used to, need, dare, shall/should, will/would, have to等。 二、基本用法 （一）can和could的用法 1．表示能力，可译为“能，会”。 I can swim. 我会游泳。 Emily can dance well and her mother could dance well when she was young. The cinema can seat 1,000 people. I could not read such an easy book when I was 7 years old. 2．表示允许、许可，常用在口语中。could比can语气上要客气。 --- Could I use your dictionary? 我可以用一下你的字典吗？ ---Yes, go ahead. 可以，用吧。（或Yes, you can. 但不能说Yes, you could.） Could/ Can you tell me how to get to the zoo? 劳驾，你能告诉我怎么去动物园吗？ He asked me whether he could take the book out of the reading room. 3. 表示可能（理论上或是逻辑判断上）。 The temperature can fall to–60℃,that is60℃below freezing.气温可降至—60℃，也就是零下60℃。 You mustn′t smoke while you′re walking around in the wood.You could start a fire. 在林子里走时勿吸烟，那样可能会引起火灾。 3．表示推测，可用于肯定句（can罕见）、否定句和疑问句，但更常见于疑问句或否定句。在此种用法中can和could没有时态的区别，只是表示可能性的大小，can表示推测的可能性比could大。 Can he be ill at home? 他会是生病在家吗？ Can the story be true? 这个故事会是真的吗？
小学英语情态动词知识点及练习
情态动词 【知识要点】: 情态动词（Modal verbs）本身有一定的词义，表示语气的单词。但是不能独立作谓语，只能和动词原形一起构成谓语。情态动词用在行为动词前，表示说话人对这一动作或状态的看法或主观设想。情态动词虽然数量不多，但用途广泛，主要有下列： can (could), may (might), must, need, ought to, dare (dared), shall (should), will (would) must not. 情态动词无人称和数的变化，情态动词后面跟的动词须用原形，否定式构成是在情态动词后面加 "not"。疑问形式是将情态动词提至主语前。个别情态动词有现在式和过去式两种形式，过去式用来表达更加客气，委婉的语气，时态性不强，可用于过去，现在或将来。情态动词属非及物动词，故没有被动语态。
【典型例题】: 【专题一】:can和could的用法 【例1】Can you lift this heavy box?(体力) 【解析】表示能力(体力、知识、技能) 【练习】 1.Mary speak three languages.(知识) 2. you skate?(技能) 此时可用be able to代替。Can只有一般现在时和一般过去式;而be able to 则有更多的时态。 I’ll not be able to come this afternoon. 当表示“经过努力才得以做成功某事”时应用be able to,不能用Can。 【例2】 -----Can I go now? ----- Yes, you can. / No, you can’t. 【解析】表示请求和允许。此时可与may互换。在疑问句中还可用could,might 代替,不是过去式,只是语气更委婉,不能用于肯定句和答语中。 【练习】 ---- I come to see you tomorrow? ---- Yes, you . ----No, you /I’m afraid not. 【例3】Can this be true? 【解析】表示推测(惊讶、怀疑、不相信的态度),用于疑问句、否定句和感叹句中。 【练习】 This be done by him. How this be true? 【专题二】may和might的用法： 【例1】----M ight/ May I smoke in this room? ---- No, you mus tn’t. 【解析】表示请求和允许。might比may语气更委婉,而不是过去式。否定回答时可用can’t或mustn’t,表示“不可以,禁止”。用May I...?征徇对方许可时比较正式和客气,而用Can I...?在口语中更常见。 【练习】 ---- I take this book out of the room? ---- Yes, you . No, you 【例2】May you succeed! 【解析】用于祈使句,表示祝愿。
