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。
情态动词 情态动词是一种本身有一定的词义，但要与动词原形及其被动语态一起使用，给谓语动词增添情态色彩，表示说话人对有关行为或事物的态度和看法，认为其可能、应该或必要等。情态动词后面加动词原形。 情态动词有四类： ①只做情态动词：must,can(could),may(might)…… ②可做情态动词又可做实义动词：need，will ③具有情态动词特征：have(had,has) to,used to，ought to ④情态动词表猜测：一肯一否三不定（must一肯，can not一否，may，might，could，三不定。） 注：mustn't代表强烈禁止 must表示主观，have to表示客观。 常用的有：can may could must have use . 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"。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。 情态动词表推测的用法小结 （一）情态动词表推测的三种句式 1．在肯定句中一般用must （一定），can,could（可能），might /may（也许，或许）。 e.g:(1)He must/can/may,might know the answer to this question. 他一定/可能/也许知道这个问题的答案。 (2)It is cold in the room. They must have turned off the heating. 屋里很冷，他们肯定把暖气关了。 2．否定句中用can’t / couldn’t（不可能），may not/might not（可能不）。
