高考考察三种形式：定义、结合时态、虚拟语气1. 情态动词基础知识。不能单独作谓语，只能和其他动词原形构成谓语。虽有时态的变化，但却没有人称和数的变化。情态动词数量不多，但用途广泛，主要有下列：有can (could), may (might), must, need, dare (dared), shall, will (would), should, ought to, have to, used to, had better, would rather 等 2.情态动词易混点比较多。以用法归类，注意各个词的用法。 一、以用法归类1.表示能力 can /could , be able to区别：be able to 可以用于各个时态；而can只可以用于现在和过去（could）。e.g.  I can do it by myself.(强调能力)e.g.  If you have a good sleep, you will be able to work out this question.（强调通过努力） 2.重点记忆，易混--表推测。表示可能性的各个情态动词，按可能性由大到小排列:must（肯定的推测）—should(按说应该)—-- --may(也许)--could(可能性比may弱)—might(微弱可能性)      may well, might well可能性会增加。 （肯定推测没有can，can无肯，may无疑。） (例外：can表示有时会   Our English teacher is considerate, helpful, and warmhearted, but sometimes she_can_be angry at our silly mistakes.) 否定推测强烈否定 不可能--can’t /couldn’t;  不应该shouldn’t； 可能不may not , might not否定推测没有mustn’t! Mustn’t—禁止！ 3.表示必要性、义务、责任必须—must/have to  责任义务—should/ought to 4.表示请求、建议、命令，允许may/ can/ could I May I sit down?—No, you mustn’t. 记住请求允许时、提出建议时 shall用于一三人称，will用于第二人称。Shall we have lunch now?     Will you do me a favour?     Shall they bring it to you?  5.表示意愿、意志、决心、允诺Shall 与二三人称连用，表示命令、法律法规规章规定、允诺。Nobody shall touch the picture in the exhibition.The first one to complete the task shall get cash reward. will ,would表示意愿、决心I will be glad if he will help me.   He told me he would do everything for me. 6.表示习惯和倾向will可以用来讲述真理，还可以叙述目前的习惯;重点是would描述过去的习惯倾向。 would和used to 的区别：would表示过去习惯性的动作，强调动作重复性。Used to表示过去的倾向或习惯，现在已经没有了。 二、以单词归类（主要情态动词）shall 在一、三人称时表示：提出建议或者请求允许。二、三表示允诺、命令、威胁、警告。Should可以表“竟然” must表示“非要，偏要”Must you make so much noise? 三、结合时态+have done must have done             推测过去一定做了某事can/could have done         过去本来能够做cannot/ couldn’t have done    过去没能做may/might have done         也许已经做了某事should have done            本应该做而实际未做shouldn’t have done          本不应该做（实际做完了）needn’t have done            不需要做（却做完了） 练习1．--What’s your name?--Khulaifi.______I spell that for you?  A.Shall               B.
