英语语法-助动词和情态动词用法及习题

目录 1助动词和情态动词的定义 (2) 2 can,may,must (3) 3 Will you~?和Shall I(we)~? (10) 4 would和should (14) 5 have to (16) 练习题 (17) 答案 (18)

1助动词和情态动词的定义 在英语中,助动词一般没有词义,主要帮助构成谓语,表示时态、语态或构成疑问及否定形式。对于助动词,同学们一般了解即可。 情态动词与助动词不同,它有词义,但它也和助动词一样,不能单独作谓语,它必须和其他动词一起构成谓语,另外重要的一点是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。 (×)She cans swim well. (×)She can swims well. (○)She can swim well. (○)She swims well. 即使主语是第三人称单数(例如she)can也不能加“s”。 句子中有情态动词can时,即使主语是第三人称单数,也不能在一般动词(例如swim)上加“s”。 1 助动词的种类 1.be(am,are,is,was,were,been,being) 它与现在分词结合,可以构成进行时态(参见第九章),与过去分词结合可以构成被动语态(参见第十三章)。 I am reading the book.我正在读这本书。 The book was written by me. 这本书是我写的。 2. have(has,had,having) 它与过去分词结合,构成完成时态(参见第十一章)。 I have finished my homework. 我已经写完作业了。 3.shall(should),will(would)

助动词与情态动词-讲解及练习测试题

助动词与情态动词 一、助动词 助动词有be, have, do, will, shall。它们本身没有词义,只和实义动词的一定形式构成复合谓语,用来表示时态和语态,构成否定、疑问及加强语气等。 1、be (am, is, are, were, been) (l)“be + -ing”构成进行时态; (2)“be + 过去分词”构成被动语态; (3)“be + 动词不定式”构成复合谓语: ①表按计划安排要发生的事。The prime minister is to visit Japan next year.总理将于明年访问日本。 ? “do + 动 只有 (1)表示能力,如:He can speak English better than you. (2)在疑问句和否定句中表示“怀疑”、“猜测”或“可能性”,如:Can this green bike be Liu Dong's? (3)表示“许可”时can可以和may换用,如:You can (may) go home now. (4)如果要表示语气婉转,可用could代替can,这时could不再是can的过去式,如:Could you come again tomorrow? (5)can和be able to都可表示能力,两者在意思上没有什么区别。但是can只能有现在式和过去式,而be able to 则有更多的形式,如:He will be able to do the work better. 2、may和might (might为may的过去式)的基本用法 (1)表示允许或征询对方许可,有“可以”之意, 如:You may use my dictionary. 在回答对方说“可以做某事”或“不可以做某事”时,一般多不用may或may not,以避免语气生硬或不容气。而用比较婉转的说法进行回答。如:---- May I use this dictionary? ---- Yes, please. 或---- Certainly. 在请求对方许可时,如果Might I…? 就比用May I…? 语气更婉转些,如:May I have a look at your new
