1、第 1 页 共 6 页牛津高中英语教学设计单 元：Unit 3 Looking good, feeling good板 块：Grammar and Usage (Question tags)Thoughts on the design: 本单元的第二个语法项目是反意疑问句。笔者采取了从情景对话、规则到语感的高中英语语法教学思路。强调了情景化的对话呈现、对比体验式的语法规则讲解，尤其是语感形成在英语语法教学中的重要作用。针对本单元的语法项目进行有效教学，首先选取能激发学生兴趣的素材，考虑它的趣味性、情景性和实用性。趣味性是指该素材能吸引学生的注意力，让他们产生学习兴趣；所谓情景性是指该素材应借助

2、于一定的情景，有助于激发学生的想象力；实用性是指该素材包括本单元的语法项目，重点突出，又简单易懂。附加疑问句的语调在具体的语境中起着至关重要的作用，所以本节课开始时借助于简单的课堂用语，既引出附加疑问句的类型，同时也运用正确的语调把要介绍的信息传达给学生。借助与对话情景呈现所要教学的语法项目，让学生在故事或对话情景中体会和领悟语法规则，进而通过老师的引导、分析和适当的练习，巩固所学习的语法项目，最终达到语法规则运用自动化。在本节课的巩固环节中充分利用现有教材资源并加以改编，让语法在一定的情景中进行操练，最后再通过让学生反复阅读，强化语感的培养和形成。Teaching aims:1.

8、前的语境中第一次口头呈现本节课的语法项目。用几个简单的课堂用语引出附加疑问句的三种类型。附加疑问句的语调在此语法项目中起着至关重要的作用。用最为简洁的日常用语来引入语调的学习。预设情景，引出主题，发挥引入的三个作用，即引起兴趣、宣告主题和推进课程。(PPT46 首先呈现口语中出现的附加疑问句的内容，然后点击展现附加疑问句的类型，教师边展现边用正确的语调读出，然后用不同的语调简要读出几个日常用语中所遇见的情景。)第 3 页 共 6 页Step 2 IntonationWe should know that reading English in correct intonation is very

9、 important.Lets look at a question tag on the screen. How should we read the sentences?You still go to the gym every day, dont you?You still go to the gym every day, dont you?You still go to the gym every day, dont you?1. When we use a question tag to ask for agreement, we expect the other person to

10、 agree with us. The question tag has a rising intonation.2. When we use a question tag to ask for confirmation, we are actually asking about something we are not sure about. The question tag has a rising intonation.Explanation本节课的设计思路为从情景、规则到语感的高中英语语法教学思路，优化语言输入，可以激发语感形成。所以语音语调在这一环节简要介绍，为最后的语感形成作好铺垫

11、。在外语教学中，语感被认为是一种重要的外语能力。新课程标准提倡教师要引导学生用观察归纳和实践的方法学习语言知识，感悟语言功能，从而提高语言的综合运用能力。（PPT7 8）Step 3 Presentation1. Please look at the pictures and read the sentences in correct intonation.Wow! I think this blouse will make me look slim, wont it?This is really difficult but I feel so strong, dont I?You must

12、get enough sleep to stay healthy, mustnt you?Eating more fruit makes me feel better, doesnt it?2. Read the dialogue and pay attention to the underlined sentences.A Dirty CarJohn, Peter and Mark are brothers. Their father has a new car, and they clean it for him, arent they? It must have just rained,

13、 and the car is very dirty, isnt it? John is looking at it, and he is talking to Peter.John: The car has hardly been cleaned for a few days, has it?Peter: No, it hasnt. Its very dirty. John: Someone ought to clean it today, oughtnt they/shouldnt they?Peter: Mark has to clean it, doesnt he? It must b

14、e his turn, isnt it?John: No, he cleaned it last time. Its your turn.Peter: No, it isnt. You always clean it after Mark.John: Oh dear, is it really my turn? In that case, Ill clean it tomorrow.Peter: Clean it now, will you? Only lazy people say theyll work tomorrow, dont they?John: Then Ill clean it

15、 the day after tomorrow.Peter: You are lazy. You ought to be ashamed. I think you should enjoy working, shouldnt you?Explanation第 4 页 共 6 页笔者利用“Welcome to the unit.”的四张图片引出附加疑问句的部分用法。引导学生关注句子中的附加疑问句部分，并运用在第一环节所教授的语调规则进行反复诵读、理解并体会黑体部分在不同句子中的意义及功能的异同。学生基本上可以利用已有的语法知识推断某些黑体部分在句子中的语法功能及其含义。若有疑问，学生之间可以先讨

16、论，确实无法解决时再寻求老师的帮助。(PPT913,用“welcome to the unit” 的情景引出附加疑问句的语调和不同的构成类型。PPT1417，呈现一篇情景对话含有附加疑问句，教师可让学生快速理解对话内容，运用正确的语调进行朗读，关注划线的部分，深刻体会。)Step4 Question Tags Ask the students to read and research the given sentences about Question tags. Discuss some laws of the use of question tags.Someone ought to cl

17、ean it today, oughtnt they/shouldnt they?1. 当陈述句的主语是 everybody、 everyone,、someone,、no one,、nobody、 somebody 或不定人称代词时，附加疑问句中的主语一般用 they，但在很正式的语体中也可使用 he。如果主语是 everything、something、 anything、 nothing、 this、that 时，附加疑问句的主语用 it。The car has hardly been cleaned for a few days, has it?2.当陈述句带有 seldom、hardl

18、y、never、rarely、 little、nobody、nowhere、 few,、nothing 等否定词或半否定词时，附加疑问句的动词用肯定形式。Their father has a new car, and they clean it for him, dont they?It must have just rained, and the car is very dirty, isnt it?3.陈述部分是并列句时，附加疑问部分的主语应与邻近分句的主语一致。Only lazy people say theyll work tomorrow, dont they?I think you

19、 should enjoy working, shouldnt you?4.陈述句部分是复合句时，附加疑问句部分的主语与主句主语一致。但如果陈述部分的主语是 I think、I suppose,、I believe 等结构时，附加疑问句部分则应与从句中的主语和谓语动词一致。但要注意否定前置的情况。Their father has a new car, doesnt he/hasnt he?Mark has to clean it, doesnt he?5.陈述句部分有表示“有” 含义的动词 have/has 时，附加疑问句中的动词部分可以用 have/has/had 或 do/does/did

20、 形式。而当陈述句部分的 have/has 不表示“有” 时，附加疑问句中的动词部分需用 do/does/did 形式。hey?It must be his turn, isnt it?6.陈述部分的动词是 must be, 且表示目前情况的猜测时，附加疑问句部分的动词要用 be 的各种人称变化形式。It must have just rained, hasnt it?It must have rained yesterday, didnt it?7.陈述部分的谓语是“must+ have done”, 表示对过去情况的猜测时，附加疑问句中的动词部分需用 did(有明确的时间状语) 或 hav

21、e/ has（无明确的过去时间状语或有与现在相关的时间状语） 。Clean it now, will you?Let us clean it now, will you?Dont clean it now, will you?Lets clean it now, shall we?第 5 页 共 6 页8. 在祈使句中，附加疑问句部分一般用“will you”、 “wont you”、 “would you”, 有时也可用“can you”、 “cant you”、 “could you”等，可根据语气选择。如果是“Lets” 开头的句子用“shall we”。 Explanation学生读完

22、对话情景之后，根据学生对情景的理解程度，可以考虑如何处理情景中的句子所反映的语法规则，从语言情景的呈现转向语言呈现的过程。笔者采用两种策略：一是直接讲解，多数学生根据有关语法知识，完全可以理解情景中的含义，只需要作出总结(1、2 两条规则)。二是采用对比讲解，对于涉及的 3、4、 5、6、7、8 六条语法规则就可运用此法。（PPT18 27 通过呈现对话中的划线句子，让学生讨论，发现特点，确定附加疑问句的规则，先出示句子，再展现规则。 ）Step 5 PracticeThere are some special usages of question tags. Ask students to

23、go through the grammar usage and finish the following.Now lets do some exercises and you will choose a letter to decide which one you will do.Explanation理解和掌握语法规则之后，学生还需要在具体的语境中灵活地运用这些规则。在此阶段，适当的习题训练能进一步帮助学生强化和巩固所学的语法规则。需要注意的是，设计的练习既要有一定的情景性、趣味性，又要多样性。笔者采用展示A、B 、 C、D、 E、F 、G、H 八张可爱的女生头像让学生先选择字母再根据所选

24、字母确定所答的题目，增加了神秘感。并且有一个字母图片下没有设置题目，选到的同学会觉得自己非常幸运。还有一道题是规则中没有提到的:如果学生选到了，不会做，老师可让学生发表自己的看法，最后老师作简要讲解。这一环节是本节课的高潮部分。 （PPT2837,让学生任选一字母确定所做的题目，例如：I choose B, 点击 B 头像，会出现题目，再点击右下角的按钮，返回选题。并不是每个图像下都有题可做，当选到没有题的时候，学生感到非常幸运，气氛非常热烈。 ）Step 6 Consolidation1. Read the following dialogue and complete it with th

25、e correct question tags.（P51 Part A）Eric: Carol, come and look at this old photo, will you? Look, this is Mum and this is Dad. But I dont know anyone else in the photo. You know who they are, (1)_ _? Carol: Let me have a look. Wow! Thats Uncle Sam. He looks really young in this photo. Now hes in Par

26、is, (2)_ _?Eric: Yeah. He went there last month. Oh, I know who the boy is.Carol: Which boy? The taller one ?Eric: No. The one who is standing with Mum and dad. Hes our cousin Rob.Carol: Oh, yes. He doesnt like talking too much, (3) _ _?Eric: No, he is very quiet. Who is the slim young lady? She loo

27、ks pretty, (4)_ _ ?Carol: You mean the one sitting in the chair reading? I think shes Ellen, Mums best friend. The man beside her is Dave. Theyre married, now, (5)_ _?第 6 页 共 6 页Eric: Yes. Are they coming to spend their summer holiday here as usual?Carol: Yes, but they didnt come last summer. Dave h

28、as really changed a lot. Hes put on a lot of weight. You can hardly recognize him in the photo, (6)_ _?Eric: Everyone in the picture seems to have put on some weight, (7)_ _?Carol: Thats the interesting thing about old photos you can always see how much time has passed since they were taken, (8)_ _?

29、Eric: Exactly!2. Pay special attention to the underlined sentences and change them with question tags.3. Read the new dialogues in correct intonation.Explanation经过了情景式的语言材料呈现、对比体验式的语法规则讲解和多样化的巩固练习，语法教学似乎大功告成。但如果仅满足于这个阶段，那只不过是实现了掌握规则、应付考试的目的，还远达不到提高语言实际运用能力的目的。语感的形成才能真正反映学生语言运用能力的提高。因此笔者充分利用课本“P51 Pa

30、rt A”的练习，重新设计了部分情景对话练习，运用正确的语音语调，优化语言的输入，激发语感的形成。通过朗读、背诵，强化语感形成。Step 7 Homework1. Finish workbook exercises on P104. Complete the sentences with the correct question tag.2. There are some special usages of question tags. Ask students to look up them in some materials.Explanation课外作业设计了两个部分，完成 workbook 的练习属于基本练习，由于面对的是刚刚进入高一的学生，附加疑问句的用法，只介绍了部分常规用法，还有深层次的语法规则或高考中的考点，让学生利用课余时间进行探究式学习，来解决第二部分的练习。
