2017中考英语语法专题详解七：情态动词、系动词
在英语中，表示主语动作或状态的词就叫做动词。根据动词的意义及在句子中的作用，可将动词分为实义动词(v)、系动词(link-v)、情态动词(modal verb)和助动词(v. aux)四种类型。
下面我们就来看看情态动词和系动词的具体用法。
一、情态动词
情态动词本身有一定的意义，但不能独立作谓语，要和动词原形一起构成谓语，表说话人的语气和态度。它没有人称和数的变化。常见的情态动词有：
1. can表示能力，有“能”“会”的意思;表示可能性，多用在否定或疑问句中;表示请求和许可。
如：The parrot can speak three languages. 这只鹦鹉能讲三种语言。
Can I borrow the book from the library?我可以从图书棺借这本书吗?
Shanghai can be very cold in March. 上海三月份可能会很冷。
拓展延伸can还有过去式could 可表“能，会”，又可以和be able to替换，而be able to 有更多时态。如：
He could swim when he was four. =He was able to swim when he was four. 他四岁时就会游泳。在一般疑问句中，can/could 常用来表示请求或征求对方意见，用could 比用can 语气更加委婉和客气。类似用法的还有Will /Would you (please)…等句型。
如：Could you tell me how I can get to the post office? 你能告诉我怎样到邮局吗? Would you please turn up the radio?请你把收音机开大点，好吗?
2.may表示“许可”时，相当于can，其否定回答用can’t/mustn’t;表推测时，常用在肯定句中，表“可能”。
如：-May I borrow your ruler?我可以借用您的直尺吗?
-No, you can't /mustn't. 不行。
She may be a teacher. 她可能是一名教师。
拓展延伸may可表示祝愿。如：May you succeed! 祝你成功!
3.must表示“必须;必要”，以“must”开头的一般疑问句其肯定回答用“must”，否定回答用“needn't”或“don't have to”。must表推测时，常用在肯定句中，是“一定”的意思，其否定形式mustn ' t表“禁止”的意思。
如：-Must I leave now?现在我必须离开吗?
-No，you needn't /you don't have to. 没有必要。
This book must be Lucy's . Look! Her name is on the book cover. 这本书是露西的。看!封面上还有她的名字。
You mustn't draw on the wall. 你不准在墙上画画。
拓展延伸must表示说话人的主观看法，只有一般现在时;have to强调客观要求，有时态、人称和数的变化。如：My mother is ill. I have to look after her now. 妈妈病了，我得去照看她。
4.need作情态动词时，常用在否定和疑问句中，表示“需要;要”的意思。
如：Need we finish the work now?现在我们需要完成这项工作吗?
They needn ' t look after him. 他们不需要照顾他了。
拓展延伸need还可以用作行为动词，可以用于各种句型。如：
Does he need any help? 他需要帮助吗?
The desk needs repairing. 这张桌子需要修理。
5.shall 用于第一人称，表示说话人征求对方意见，过去式为should;will 用手第二人称的疑问句中，表示说话人向对方提出请求和建议，过去式为would。
如：Shall I go shopping with you?'我可以同你去购物吗?
I don't know what I should do next. 我不知道下一步该干什么。
Would you please come a little earlier?请你来早一点好吗?
6.情态动词had better的用法
(1)had better 后接动词原形，表劝告、建议，意为“最好”。“You'd better… ”含有强制命令的语气，对长辈不宜使用。
如：You'd better ask that policeman over there. 你最好问一下那边的那个警察。
(2)慎用had better! 注意以下四条：
①had better表达的是说话者强硬性的建议，告诫别人(包括自己)如何做。如：Granny, the hospital is not very near. We'd better catch a bus. 奶奶，医院不是很近。我们最好坐公共汽车。
②had better不用于礼貌的请求或征询，它隐含一种警告或威胁。如：You ' d better finish the work today and bring it tomorrow. 你最好今天就把作业完成，明天带来。
③had better意思接近should，但它除了表示语气强硬以外，还表示马上要去做的事情，比should更紧迫。如：You’d better see a doctor at once. 你最好马上去看医生。
④had better不含比较的意思，该结构表示“It would be good to… ”，而不是“It would be better to…”。
二、系动词
系动词有实际意义，但不能单独做谓语，必须与表语一起构成句子的谓语，说明主语的性质、状态或身份等。它分为完全系动词和不完全系动词。
1.完全系动词(be)可接名词、代词、形容词、副词、介词短语、非谓语动词短语、句子做表语。如：I'm a student. 我是个学生。(名词) He is fine. 他很好。(形容词) It is me. 是我。(代词) Are you there?你在那儿吗?(副词) She is at school. 她在学校读书。(介词短语) He is to come soon. 他过会儿该来了。(不定式) My job is teaching English. 我的工作是教英语。(动词的ing形式) My idea is that we will start now. 我的想法是我们现在就开始。(句子)
2.不完全系动词(get，turn，feel，smell，look，sound，taste)一般只接形容词做表语。如：When spring comes, it gets warmer and warmer.
春天来了，天气变得越来越暖和了。Food may go bad soon if it is not put into a fridge.
食物如果不放进冰箱里就会很快变坏。My brother became / turned a teacher after his graduation.
我哥哥毕业后就当上了老师。(注意become和turn的用法区别)
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）
关于be动词、情态动词和实义动词的区别 到目前为止，我们主要学习了三类动词：be动词、情态动词和实义动词。下面我们分别来讲一下它们得用法。 1.be动词属于系动词, 在句子中主要表现为三种形式：am is、are。 后面往往接形容词或名词做表语。如： (1)I’m young. (young形容词做表语) (2)He is a boy.( a boy名词做表语) 含有be动词的句子在进行否定、疑问句变化时，都要在be动词上变化。 (1)变为否定句：主语+be+ not+其他。即，直接在be后not. ①I’m a Chinese boy.(变为否定句) ②You are good. (变为否定句) ③He is strict with us. (变为否定句) ④She is from America. (变为否定句) 以上四个句子中都含有am、is或are，变否定句时，直接在am 、is、are后面加上not.即： ①I’m not a Chinese boy. ②You are not good. ③He is not strict with us. ④She is not from America. (2)变为一般疑问句：Be+主语+其他？即把be动词提到主语的前面。注意：当肯定句主语为第一人称I和We时，变一般疑问句要变为第
二人称，be动词也要相应的变为are.同样肯定句中的my和our 也要变为your. ①I am a boy. (变为一般疑问句) →Are you a student? ②We are good friends. (变为一般疑问句) →Are you good friends? ③She is from America. (变为一般疑问句) →Is she from America? ④He is strict with us. (变为一般疑问句) →Is he strict with us? (3)变特殊疑问句：一般的要求为“对划线部分提问”，即用特殊疑问词代替划线的部分，后接省略划线部分的一般疑问句（一般不再出现划线部分）。如： ①I’m well.（对划线部分提问） →How are you? ②She is from America. （对划线部分提问） →Where is she from? 2.关于情态动词：初中我们常用的情态动词主要有：can、 may、 must、need。我们这里主要以can为例来说明情态动词的用法。 情态动词后面必须接动词的原形。情态动词can的用法类似于be动词。不论主语为第几人称，变否定就是在can后加not.变

情态动词与虚拟语气 【语法要点】 情态动词 所谓情态动词是指它含有一定的含义，可以表达某种感情和说话的语气，但是它不可以单独使用 作谓语动词。学习情态动词主要学习英语国家的语言习惯和表达法，特别是在口语中不要过分追求原理，更不要不根据说话场合而进行推理，编造出一些语法结构正确的中文式英语。 一、情态动词的类型 1.只作情态动词的有：must、can、could、may、might、ought to 2.既可作情态动词又可作实义动词的有：need、dare 3.既可作情态动词又可作助动词的有：shall、should、will、would 二、情态动词的特征 1.表示说话人的情感态度，不能单独作谓语，与行为动词或连系动词一起作谓语。 2.情态动词没有人称和数的变化，后接动词原形。 3.具有助动词的特征：可用来构成否定句、疑问句或简短答语。 三、情态动词的用法 1.表示能力 （1）表示现在的能力，用can 或be able to。表示一般的能力时多用can，表示“经过努力成功 的做成某事”用be able to。 （2）表示过去的能力，用could或was/were be able to。区别同上。 （3）表示将来的能力，用will be able to。 2.表示推测、可能性 （1）can 用在肯定句中表示客观的可能性，而不表示具体事情实际发生的可能性。 例如：Accidents can happy on such rainy days. （2）表示具体事情实际发生的可能性的情态动词，其表示可能性的层次如下表： 情态动词肯定式否定式疑问式 must 必定、必然、一定 will 很可能、大概不会、不该会,,吗？ would 可能性较will 小不会、不该（较won’t 弱）会,,吗？（较will 弱） should 应该会、理应（表示合乎理想的情况或结果） ought to 与should 同义 can 一定不会、不可能（否定推测）有可能吗？ could 可疑的可能不可能（与can’t 同义）有可能吗？（较can 弱）may 或许、可能、说不定可能不 might 或许、可能（较may 弱）可能不（较may not 弱） 注意→（1）may，must 常用于肯定句，一般不用于否定句和疑问句。 （2）can 常用于否定句，疑问句和感叹句中，表示疑惑、惊讶或不相信等意思。could 既可用于肯定句，又可用于否定句、疑问句中。

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.
