1、情態動詞 一：情態動詞的用法： 常用的情態動詞有can，may，must，need,should, had better.1. can 的用法： 表示能力 “能，會” eg: He can speak a little Japanese.他會說一點日語。 表示請求或許可 “可以” eg: Can I help you? 要我幫忙嗎? 表示猜測 “可能” eg: Where can she go now? 她可能到哪里去了呢? 2.may 的用法：表示請求或允許 “可以”“準許” eg: May I go home，please?請問我可以回家嗎? 表示可能性 “ 可能”、也許” eg: I t

2、hink it may rain this afternoon. 我想今天下午可能下雨。 注：might為may的過去式，但也可以代替may，語氣較為婉轉客氣或更加不肯定。 eg: He might not come today.今天他也許不來了。(語氣不肯定) You might also get a headache when you work too hard，當你工作太努力時，你也可能患頭痛3. must的用法： 表示義務、必要或命令 “必須、應該” eg: You must come early tomorrow你明天得早來。 表示推測時“肯定，一定” eg: They must b

3、e at home.The light is on 他們肯定在家,燈亮著呢. must not 禁止，不許 eg: You must not tell lies. 你不許撒謊。 注意： must開頭的疑問句，其否定回答通常用 don't have to 或needn't 。而不用mustn't eg: -Must I finish my homework first? 我必須先完成作業嗎？ -No, you don't have to/ needn't. 不，你不必。 can 和 must在 表推測時，can一般否定句中，而must 常用于肯定句中。 e

4、g: It can not be Li Lei 那個人不可能是李磊 It must be Li Lei 那個人肯定是李磊。4. need 的用法： 情態動詞“需要,有必要”一般用于否定句或疑問句中。eg: You needn't come here this afternoon.你今天下午不必要過來。 行為動詞 “需要, 有必要” 可以用于各種句式中。 eg: You don't need to go now. 你不必現在就走。 I need to have a rest. 我需要休息一下 Do we need to finish all the work today? 我們今

5、天需要完成所有的工作嗎？need的用法的助記口訣：實義動詞表“需要”，后接名、代、不定式。 need后接動名詞，主動形式表被動。情態動詞表“需要”，沒有人稱 數之變。 其后直接加動原，多用疑問與否定。5.征求許可或給予許可，“我可以···？”用句型“Can/May/Could/Might I.?”其中"Can I.?"屬于非正式用法，"May I .?"屬于正式用法。"Could/Might I.?"的回答通常不用could或might，而用may或can或其他表示客氣的詞語。6.肯定句中表推測“可能”：

6、can,could,may,might都可以在肯定句中表“可能”。其中can的語氣最強，可能性最大，其余依次遞減。 肯定句中表推測“一定，肯定”用must.7.疑問句中表推測“可能”：用can,could,might,而不能用may. mustn't 不表示推測，而表示禁止。 意義為“禁止，不準”8.否定句中表推測： may not/might not：可能不 can not/could not： 不可能 eg: You may not be right你也許不對. You can not be right你不可能對.9.以may（表許可或請求）開頭的一般疑問句的肯定回答用may，否定

7、回答用mustn't或can't。10.表示“必須”時，must表示主觀看法，have to強調客觀需要。11.ought to和should兩者都表示應該，但是ought to比should語氣強。12.would rather與than連用，其結構是：would rather.than.或would.rather than.。would(rather)和than后面都接動詞原形，如果用的動詞相同，則than后省去該動詞。would rather.than.的意義為“寧愿···而不是···”eg:I would ra

8、ther play football than baseball.我寧愿踢足球而不愿打棒球。13. 情態動詞的助記口訣： 情態動詞兩要點：動詞原形跟后邊 沒有人稱 、數之變 can 表能力 may許可 must來把責任擔（必須） 否定回答need換。 need需要 dare敢 should應該 would like 愿(意) have to“ 不得不”表客觀。14.had better用法的助記口訣： 表示“建議”和“忠告”，had better 為最好。 建議某人“最好不···”，要用 had better not do。2003-2008年河南及全國中考題20
