重难点02 情态动词-2021年中考英语【热点•重点•难点】专练（安徽新题型）

重难点02 情态动词 【中考变化】 情态动词有具体的词义，但也同助动词一样，需要与其他词语一起构成句子的谓语，另外情态动词没有人称和数的变化，情态动词后必须跟动词原形。主要考查can,could,will,would,may,might,must,shall,should,need的用法。含有情态动词的疑问句的回答；不同情态动词的否定意义；情态动词表示推测的用法以及情态动词的易混知识点（can,be able to;may be,maybe;can’t,mustn’t） 【满分技巧】 1.充分利用句子语境 综观历年中考英语情态动词的考查情况，有相当一部分考题从本质上看都是在考查情态动词在具体语境中的运用，即只要考生能弄清各个被考查情态动词的意思，就可作出正确选择。 2.根据时间确定时态 即要分清情态动词表推测时涉及的是现在情况还是过去情况。原则上说，若对现在情况进行推测，情态动词后接动词原形或进行式;若对过去情况进行推测，则后接动词的完成式(这通常是高考的重点);若是对正在发生的情况进行推测，后接动词的进行式。 3.注意分清适用句型　即要分清所考查的情态动词是用于肯定句型，还是用于疑问句型或否定句型，同时还要注意情态动词在某些特殊情况下所使用的特殊句型。 【限时检测】 1．—________ we leave the library before 5 o’clock? —No, you needn’t.
