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）

【英语】高中英语情态动词练习题

【英语】高中英语情态动词练习题一、单项选择情态动词 1．The professor warned the students that on no account ________ use mobile phones in his class. A．should they B．they should C．dare they D．they dare 【答案】A 【解析】【详解】考查部分倒装和情态动词。句意：这位教授警告学生们，在他的课堂上，决不应该使用手机。on no account意为“决不”，否定词放在句首，句子使用部分倒装，排除B、D项；这里表示应该，故选A。 2．What a pity!

A．need have done B．must have done C．can have done D．might have done 【答案】D 【解析】【详解】考查虚拟语气中的情态动词。句意：真遗憾啊！考虑到他的能力和经验，他也许可以做得更好。can have done较少使用此结构，表示对过去行为的怀疑；用于疑问句时意为“难道真的做了吗”，表示怀疑；need have done需要做某事，实际上却未做（表示虚拟语气）；must have done一定做了某事（表示对过去发生的事情的肯定推测）；might have done表示对发生过的事情的推测，意思是“可能已经”或“也许已经”，用于肯定句中。故D正确。【点睛】本题是高考必考考点，一定要牢记句型意思。must have done过去肯定做了某事。should have done本应该做而实际未做。can’t have done过去不可能做了某事；shouldn’t have done 本不应该做而实际做了。need have done本有必要做某事而没做；needn’t have done本没有必要做某事；注意没有mustn’t have done的形式。 3．—Jim ________ what I said annoying though he didn’t say anything. — So you mean you will have to apologize to him?

小学英语情态动词知识点及练习

情态动词【知识要点】: 情态动词（Modal verbs）本身有一定的词义，表示语气的单词。但是不能独立作谓语，只能和动词原形一起构成谓语。情态动词用在行为动词前，表示说话人对这一动作或状态的看法或主观设想。情态动词虽然数量不多，但用途广泛，主要有下列： can (could), may (might), must, need, ought to, dare (dared), shall (should), will (would) must not. 情态动词无人称和数的变化，情态动词后面跟的动词须用原形，否定式构成是在情态动词后面加 "not"。疑问形式是将情态动词提至主语前。个别情态动词有现在式和过去式两种形式，过去式用来表达更加客气，委婉的语气，时态性不强，可用于过去，现在或将来。情态动词属非及物动词，故没有被动语态。

【典型例题】: 【专题一】:can和could的用法【例1】Can you lift this heavy box?(体力) 【解析】表示能力(体力、知识、技能) 【练习】 1.Mary speak three languages.(知识) 2. you skate?(技能) 此时可用be able to代替。Can只有一般现在时和一般过去式;而be able to 则有更多的时态。 I’ll not be able to come this afternoon. 当表示“经过努力才得以做成功某事”时应用be able to,不能用Can。【例2】 -----Can I go now? ----- Yes, you can. / No, you can’t. 【解析】表示请求和允许。此时可与may互换。在疑问句中还可用could,might 代替,不是过去式,只是语气更委婉,不能用于肯定句和答语中。【练习】 ---- I come to see you tomorrow? ---- Yes, you . ----No, you /I’m afraid not. 【例3】Can this be true? 【解析】表示推测(惊讶、怀疑、不相信的态度),用于疑问句、否定句和感叹句中。【练习】 This be done by him. How this be true? 【专题二】may和might的用法：【例1】----M ight/ May I smoke in this room? ---- No, you mus tn’t. 【解析】表示请求和允许。might比may语气更委婉,而不是过去式。否定回答时可用can’t或mustn’t,表示“不可以,禁止”。用May I...?征徇对方许可时比较正式和客气,而用Can I...?在口语中更常见。【练习】 ---- I take this book out of the room? ---- Yes, you . No, you 【例2】May you succeed! 【解析】用于祈使句,表示祝愿。

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.
