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）

be动词、助动词、情态动词讲解 (基础篇) 1、be动词的用法。 英语中，be动词选用单数还是复数，要由主语来定，主语是单数，就用单数，反之用复数。 ◆句中含有be动词时： 肯定句：主语＋be ＋其他 否定句：主语＋ be ＋ not ＋其他 一般疑问句： Be ＋主语＋其他＋？ 特殊疑问句：疑问词（what / who / when / where）＋ be ＋主语＋其他＋？ I am a teacher. You are right. She is 16 years old. My father is at home. The students are playing games. My teacher was ill yesterday. There is a picture on the wall. There are two books on the table. ★ be动词用法歌： 我用am，你用are，is 连接他她它。单数名词用is，复数名词全用are。 变疑问，往前提，句末问号莫丢弃；变否定，更容易，be后not莫忘记； 疑问否定任你变，句首大写莫迟疑。 ★ be动词作谓语，它后面一般跟名词、形容词或介词短语。 她个子很高。她在教室里。 她是一个高个子的女孩。 2、助动词的用法。 英语句子按正常语序是“什么人或事物” + “做什么”，即，我们常说的“主语 + 谓语 + 其他”。 ①主语为I 或复数名词、代词时： 肯定句： I / We / They / The students ＋动词原形＋其他＋。 We watch TV every night. 变否定：主语＋ don’t ＋动词原形＋其他＋。 We don’t watch TV every night. 一般疑问句 Do + 主语 + 动词原形 + 其他 + ？ Do you watch TV every night? Yes, we do. / No, we don’t. 特殊疑问句：疑问词 + do + 主语 + 动词原形 + 其他 + ？ How often do you watch TV?
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
