专项复习 情态动词 九年级 半壁店育才学校 郝国艳情态动词(mod. v)重点：掌握情态动词的语法功能难点：掌握情态动词的提问与回答、表示推测、判断的用法中考考点知识梳理情态动词的意义：情态动词有自己的词汇意思，不能独立作谓语，须跟动词原形。表示说话人的语气、情态。一、情态动词的类型：只作情态动词的有： can(could),may(might), must可作情态动词也可做助动词的有：need可作情态动词也可作助动词的有：will(would),shall(should)二、情态动词的特征 有一定的词义，但不能单独做谓语，必须和行为动词和系动词连用，构成谓语；无人称和数的变化，否定时，在情态动词后加not ，疑问时，将情态动词提至主语前（have to除外）。 She can speak English. She cant speak French. What can she speak？ He has to walk home. Does he have to walk home? He doesnt walk home.三、情态动词的用法情态动词用法例句can1. 表示具有某种能力，“能、会，2. 表示允许，征求意见，一般在问句中出现，“可以”， Can I ？“ 我可以吗？” 3. 表示可能性，多用于否定句和疑问句。“不可能，不会” “可能吗？” She can dance now. Can I go home now? Can it be true? Miss Gao cant be in the office.I saw her in the library just now.could1. 是can的过去式，表示过去的能力。2.在问句中，表示比can更为委婉的请求。He could swim when he was five.Could you help me?may(might)1. 表示许可，“可以”2. 表示可能，常用于肯定句中。might 表推测时可能性低于may3. 以may 引导的一般疑问句的否定答语为cant/mustnt4. 表示祝愿，“祝.”May Iuse your pen?The dictionary must be mine.

(No, you cant.)May you be happy.must1. 表示说话人的主观意志，“必须”。2. 表示猜测，“一定”，只用于肯定句中。3. mustnt,表示“禁止，不允许”。4. must 引导的疑问句，否定回答用neednt/dont have toYou must work hard at English.They must be tired after a long work.You mustnt park here.-Must I finish it now?-No, you neednt/dont have tohave to1.表示客观需要，“不得不，必须”，有人称、时态和数的变化，后跟动词原形。He had to stay at home because of the heavy rain.need1. 作情态动词意为“需要”，常用于疑问句和否定句中。2. 作行为动词，有人称和时态的变化。Sb need to do dthSth need doing/to be done3. 以need 引导的疑问句，肯定答语用must 否定答语用neednt。He neednt come here.He needs to see a doctor.-Need I go there tomorrow?-Yes, you must./No, you neednt.shall 用于第一人称表示征求意见、询问 Shall we go to the supermarket?should 用来表示“义务、责任”，意为“应该”。 用于各种人称You should obey the traffic rules.would1. 用于第二人称表示询问、请求。2. 用来表示过去的意愿或委婉的请求。Would you tell me the way to the park?had better意为“最好”，没有人称和数的变化，后接不带to的不定式，通常缩写为 d better否定为had better not do sthYoud better go there by bus.注意 1. 表示推测含义情态动词must, may , might, could, may , cant表示推测含义与用法后面都接动词原形，都可以表示对现在情况的揣测和推断但他们 含义有所不同 must 一定 肯定 (100%的可能性) may, might, could有可能，也许 (20%80%的可能性) cant 不可能，不会 (可能性几乎为零) The dictionary must be mine. It has my name on it. The CD might/could/may belong to Tony because he likes listening to pop music. The hair band cant be Bobs. After all, he is boy! 注意 2 易混词语辨析1. can 与be able to两者表能力时用法相同，但can只有现在式和过去式，而 be able to 可以用于多种时态。Jim cant drive a car. I will be able to see him next week.2. may be 与maybemay be ：may 是情态动词 ，后接动词原形be， 用于句中。maybe ：是副词，意为“大概，也许” 相当于perhaps ，用于句首。Maybe he is right. He may be right. Im not sure.3. cant mustntcant 表示“不能，禁止 ，肯定不是” mustnt 表示“禁止”，不表示推测。 Im sure he cant be at home. His door is locked. You mustnt take the book out of the library.4. must have tomust 侧重个人意识和主观上的必要。 Have to 侧重客观上的必要。可用于现在时、过去式和将来时。变为否定句和疑问句时要借助动词来完成。know I must study hard.I have no moneySo I have to borrow some from my friend.四、情态动词的被动语态含有情态动词的被动语态结构为：情态动词+be+done（过去分词）。做题时要兼顾情态动词和语态这两个方面的用法。More and more trees must be planted in China.中考河北真题练（ ）1.（2006河北 44）. -Listen !
