八年级英语上 Module Two语法部分教案.doc

一. 教学内容：Module Two 语法部分二. 重点、难点：情态动词can三. 具体内容情态动词can（及其它几个常见的情态动词的用法）1. 情态动词的语法特征1） 情态动词不能表示正在发生或已经发生的事情，只表示期待或估计某事的发生。2） 情态动词除ought 和have 外，后面只能接不带to 的不定式。3） 情态动词没有人称，数的变化，即情态动词第三人称单数不加-s。4） 情态动词没有非谓语形式，即没有不定式，分词等形式。2. 情态动词的用法1）cancould 表示能力；可能 （过去时用could），只用于现在式和过去式（could）。注意：could不表示时态（1）提出委婉的请求，（注意在回答中不可用could）。Could I have the television on?Yes, you can. / No, you cant.（2）在否定，疑问句中表示推测或怀疑。He couldnt be a bad man. 他不大可能是坏人。2） 比较may和might （1） 表示允许或请求以及没有把握的推测；may 放在句首，表示祝愿。May God bless you!He might be at home.注意： might 表示推测时，不表示时态。只是可能性比may 小。Peter _come with us tonight, but he isnt very sure yet. A. mustB. may C. can D. will答案：B。表可能性只能用may.此句意可从后半句推出。3） 比较have to和must（1）两词都是“必须”的意思，have to 表示客观的需要， must 表示说话人主观上的看法，既主观上的必要。My brother was very ill, so I had to call the doctor in the middle of the night.我弟弟病得很厉害，我只得半夜里把医生请来。（客观上需要做这件事）He said that they must work hard. 他说他们必须努力工作。（主观上要做这件事） （2）have to有人称、数、时态的变化，而must只有一种形式。但must 可用于间接引语中表示过去的必要或义务。He had to look after his sister yesterday.（3）在否定结构中： dont have to 表示“不必”mustnt表示“禁止”You dont have to tell him about it. 你不一定要把此事告诉他。You mustnt tell him about it.你一定不要把这件事告诉他。4） must表示推测（1） must用在肯定句中表示较有把握的推测，意为“一定”。（2） must表对现在的状态或现在正发生的事情的推测时， must后面通常接系动词be 的原形或行为动词的进行式。 You have worked hard all day. You must be tired. 你辛苦干一整天，一定累了。（对现在情况的推测判断）He must be working in his office. 他一定在办公室工作呢。比较： He must be staying there. 他现在肯定呆在那里。He must stay there. 他必须呆在那。 （3）must 表示对已发生的事情的推测时，must 要接完成式。I didnt hear the phone. I must have been asleep.我刚才没有听到电话，我想必是睡着了。5） 否定推测用cant。If Tom didnt leave here until five oclock, he cant be home yet.如果汤姆五点才离开这儿，他此时一定还未到家。6） 表示推测的用法can, could, may, might, must 皆可表示推测，其用法如下：（1）情态动词+动词原形。表示对现在或将来的情况的推测，此时动词通常为系动词。I dont know where she is, she may be in Wuhan.（2）情态动词+动词现在进行时。表示对现在或将来正在进行的情况进行推测。At this moment, our teacher must be correcting our exam papers.这时，我们老师想必在批改试卷。7） 情态动词的回答方式问句肯定回答否定回答Need you?Yes, I must.No, I needntMust you?Yes, I must.I dont have to. 【典型例题】1. Could I borrow your dictionary?Yes, of course, you_. A. mightB. will C. can D. should答案：C。could表示委婉的语气，并不为时态。答语中of course，表示肯定的语气，允许某人做某事时，用can和 may来表达，不能用could或might。复习： will 与you连用，用来提出要求或下命令。should与you 连用，用来提出劝告。2. Shall I tell John about it?No, you _. Ive told him already.A. needntB. wouldntC. mustntD. shouldnt答案：A。neednt 不必，不用。 wouldnt 将不，不会的。 mustnt 禁止、不能。 shouldnt不应该。本题为不需要，不必的意思，应用neednt。3. Dont forget to come to my birthday party tomorrow._.A. I dont B.I wont C. I cantD. I havent 答案：B。will既可当作情态动词，表请求、建议、也可作为实义动词表“意愿、意志、决心”，本题表示决心，选B。以上为几个常见的情态动词的用法。我们该模块中主要讲的是can。如果你想表达自己能做某事，你可以说：I can speak English. 我会说英语。I can dance. 我会跳舞。I can play table tennis. 我会打乒乓球。在表达“某人能做某事”时，可以用“can +动词原形”表达。如果表达自己不能做某事，可以在can后直接加not，成为cannot，也可以缩写为cant。如：I cannot play football. 我不会踢足球。Dick cant speak Chinese. 迪克不会说汉语。can是情态动词，没有人称和数的变化。不论表示谁能（不能）做某事，都是用can（not）。Daming can ride a bike. He cant drive a car. 大明会骑自行车，他不会开汽车。They can swim. They cant dance. 他们会游泳，不会跳舞。She can play football. She cant play basketball. 她会踢足球，不会打篮球。如果是询问某人能不能做某事，则要使用can的疑问形式，即将can提至句首。如： 一Can you speak Chinese?你会说汉语吗? 一Yes，I can.No，I cant.是的，我会。不，我不会。 一Can she swim? 她会游泳吗? 一Yes，she can.No, she cant是的，她会。不，她不会。肯定否定疑问回答I can play footballI cannot （cant） playfootball.Can you play football?Yes, I can.No, I cant.He / She can speak English.He / She cannot （cant） speak English.Can he / she speak English?Yes, he/she can.No, he / she cant.We can swim.We cannot （cant） swim.Can we swim?Yes, we can.No, we cant.They can play table tennis,They cannot （cant）play table tennis. Can they play table tennis?Yes, they can.No, they cant.It can speak like man.It cannot （cant） speak like man?Can it speak like man?Yes, it can.No, it cant.注意：否定形式cannot比缩写形式cant要正式，口语中一般用缩写形式。can可以表示多种含义，而这里的can所表示的都是能力。表中Can we swim?好像与实际不符，其实现实生活中还是有这种情况的。如反问句“我们会游泳吗?当然会了。”（Can we swim? Certainly we can.）另外，can表示的“能力”为现在的能力，而不能表示过去或将来的能力，这一点一定要注意。Text of Module Two1. Please welcome Betty and Tony to our school.请大家欢迎贝蒂和托尼到我们学校来。这里welcometo表示“欢迎来”，如：Welcome all of you to our city. 欢迎你们所有人来我们的城市做客。2. My father is a teacher at Beijing International School. 我父亲是北京国际学校的一名教师。My mother is a doctor at the hospital.我母亲是医院里的医生。My mother is an English teacher in a university in Beijng. 我母亲是北京一所大学的英语教师。 这几个语句中分别用了in和at表示在什么地方工作。介词at和in都可以用来表示地点。 通常，at表示较小的地点，in表示较大的地点。例如： She is at the library. 她在图书馆。They like that big shop in London. 他们喜欢伦敦的那家大商店。情态动词专练：例1 1.
