Period 3Extensive Reading
The General Idea of This Period
This period includes the reading of English jokes on Page 22 and the reading task AN APRIL FOOL’S JOKE:THE NOODLE HARVEST on Page 59.The reading in Using Language introduces the kind of humour we can laugh at—verbal jokes.They use a “play on words” to be funny.The reading task tells us a good joke told on BBC on April Fool?s day.
The two reading passages can be given to the students as extensive reading tasks.They are expected to appreciate and enjoy the fun by studying the English jokes.And next the students are encouraged to involve in a group activity—change the joke into a short play and then act it out.As for the reading task,the students are expected to go through the questions following the passage first to predicate what the story is about and then skim the passage for the keys to the questions.

Teaching Procedures
Step 1 Revision
T:Glad to see you,everyone!This is the first period of today.You don?t feel hungry,do you?
Ss:No,we don?t,but we feel hungry for more humour.
T:OK,be quick!Let?s first check your homework.Look at the screen and fill in the missing words and try to retell the reading passage.
Not all the _________ is kind. Some are bad, others can inspire people. Some actors can _________ us with the characters they are playing.Chaplin was such an actor.He became famous for using a _________ form of acting in silent films.The little tramp gives people courage to overcome _________ with his firm _________ and he is always kind even when people are _________ to him.Chaplin developed his own acting style,the one in one of his most famous films _________ __________ __________,he uses __________ humour to eat a __________ shoe. Chaplin produced,__________ and wrote the movies he __________ in.He was given a special Oscar for his __________ work. He and his movies are __________ by people __________ the world.
T:Not all the humour is kind.Some are bad,others can inspire people.Some actors can astonish us with the characters they are playing.Chaplin was such an actor.He became famous for using a
particular form of acting in silent films.The little tramp gives people courage to overcome difficulties with his firm determination and he is always kind even when people are unkind to him.
S:Now let me go on with the second paragraph.Chaplin developed his own acting style,the one in one of his most famous films The Gold Rush,he uses nonverbal humour to eat a boiled shoe.Chaplin produced,directed and wrote the movies he starred in.He was given a special Oscar for his outstanding work.He and his movies are remembered by people throughout the world.
ideas of what you are reading,and if you like,you can also say or write something about what you are reading with the help of the notes after class,and you will see it is not so difficult to do so. Step 2 Reading in Using Language
T:So much for your homework.Just now you said you felt hungry for more humour,didn?t you? Ss:Yes.
T:OK,please turn to Page 22 and look at the reading.The reading will satisfy you by introducing the kind of humour we can laugh at—verbal jokes.They use a “play on words” to be funny.I?d like you to read the three jokes and then match the joke with the explanation.If you like,you may have a discussion.And then we?ll check the answer.OK,read them.
T:Have you finished the reading?Are the jokes funny?
Ss:Yes,they are very funny.We?ve never found that English jokes so funny.
T:What?s the an swer?
S:The answer is 1 to B,2 to C and 3 to A.
T:Good.Now,another joke is waiting for you.Please read the next joke on Page 22.And then finish the questions followed.
Three minutes later.
T:Now decide which of these two kinds of jokes you like better.Give your reason.
S:I find the first kind jokes are easier to understand.
S:We must understand the background of the funny story at first,and then we can know what a humour Sherlock Holmes was.I think to understand this kind of jokes needs wisdom to understand.We must know that he was a detective,so he was always thinking of the things such as stealing.
T:What you said is reasonable.Now let?s listen to the tape,pay attention to the intonation,and try to bring out the humourous meaning.
After listening.
T:Now I?d like you to change the joke about Sherlock Holmes into a short play and first act it out in groups of three-Holmes,Watson and a narrator.Try to imitate the intonation so that you can bring out the humourous meaning,and then we will ask some groups to come to the front and act their plays out,and see which group will be the best.
Several minutes later.
T:Excellent performances!Thank you.Now we?ll go to the reading task,it is a very famous story.It once made fun of many people.Now let?s turn to P age 59.
Step 3 Reading task on Page 59
T:The reading task gives us another joke.The title is An April Fool’s Joke:The Noodle Harvest.I believe that all of us know April Fool?s Day.
Ss:Yeah.
T:Now,we are going to read the text.What will it tell us?
At first,please read the questions below the text;maybe they can give us some details of the text. Give the students one minute to go through the questions.
T:OK,what can you get from the questions?
S:From the first question,we can guess that the story hap pened on April Fool?s Day.
S:From the second question,we can see that the program Panorama is strange.
S:I think that BBC was making a joke with people.We know noodle very much.It?s impossible to grow noodle trees.
S:From the last questions I can see that this story gives us a way to treat something around us. T:OK,I think all of your guesses are reasonable.Now let?s read the text and make sure whether your guesses are right.While you are reading,try to find out the answers to the four questions,you may have a discussion to check their answers.
Several minutes later.
T:Well,have you finished the text?
Ss:Yes.
T:What?s the answer to the first question?
S:On April Fool?s Day,children make fun of each other.
T:Right.Why did people believe the program Panorama?
S:I think the most important reason is that there were always many serious program on the television.And the Panorama explored problems and progress all over the world.So nobody was surprised when it reported the excellent noodle harvest.If the news was not from such a famous and serious program,nobody would believe it.
T:I think so.People would like to believe those who are authority.Any opinions?
S:I think there is another important reason.It is that the reporter showed many noodle trees with the farmers pulling noodles off them and putting them into baskets.
T:I agree with you.We often say that seeing is believing.Any opinions?
S:I think that their cheating was true.It also mentioned two reasons for the good crop:an unusually warm winter and the disappearance of the insect that attacked the noodle crop every year.What?s worse,they still gave some other details to prove the news.If I was hungry then,I would be cheated too.
T:Maybe.Well,do you think the advice that the BBC gave people who asked how to grow noodle trees was serious?Give a reason.
S:No,it could not be serious as no trees could be grown in this way.
T:I agree with you.What would you do to find out whether a story like this was true?
S:I think at first you must think whether it is possible to have noodle trees.Noodle doesn?t have any life,how could they be grown?
T:You mean that when we hear a story,we should at first think about its nature.
S:Yeah.
T:Well,do you have any other opinions?
S:The reason that there were so many people caught in is that they forgot that day was April Fool?s Day.If they knew this,I believe that they would think whether it was true or false.
T:That?s right.If I was not sure whether a story was true or not,I would go the library to check the facts in an encyclopedia or go on the Internet.
T:OK,this class is full of joy and thinking.I really should be proud of you,for your good performances and logical thinking.
Step 4 Homework
T:So far we have learned much about humour and appreciated many English jokes,and funny stories.So I?d like each of you to prepare one English joke or funny story and tomorrow we will share them in class to make our class more interesting and lovely.Another task as your homework,read the text once again and try to find the sentences in the reading passage where the -ing form is used and tell the function of each -ing form word or phrase.In the next period,we will learn the usage of -ing form.Well,that?s all for today.See you tomorrow.
Ss:See you.

A kiss
At a dinner party,the speaker,who was the guest of honor,was about to deliver a speech when his wife sitting at the other end of the table,sent him a piece of paper with the word “KISS” scribbled on it.
The guest seated next to the speaker said,“Your wife must love you very much,I see her send you a …KISS? before you begin your speech.”
The speaker smiled and explained,“You don?t know my wife.The …KISS? she gives me stands for …Keep It Short,Stupid.?”
Key to one’s success
One day a father was teaching his son and said,“The keys to your success are keeping your word and cleverness.Once you promise somebody a promise,you must carry it out on matter what will happen.This is called …keeping one?s word.?”
“What is cleverness?”asked his son.
“Cleverness is that you?ll never make such a promise,” the father answered.
Deadly Email
An Illinois lady left the snow-filled streets of Chicago for a vacation in Florida.Her husband was on a business trip and was planning to meet her there the next day.
When she reached her hotel,she decided to send her husband a quick e-mail.Unable to find the scrap of paper on which she had written his email address,she did her best to type it in from memory.
Unfortunately,she missed one letter and her note was directed instead to an elderly widow,whose husband had passed away only the day before.
When the grieving widow checked her e-mail,she took one look at the monitor,let out a piercing scream and fell to the floor in a dead faint.At the sound,her family rushed into the room and saw this note on the screen:
DEAREST HONEY:JUST GOT CHECKED IN.EVERYTHING PREPARED FOR YOUR ARRIV AL TOMORROW.
P.S.SURE IS HOT DOWN HERE.
Only when he’s drunk
John and Jessica were on their way home from the bar one night and John got pulled over by the police.The officer told John that he was stopped because his tail light was burned out.John said,“I?m very sorry officer,I didn?t realize it was out,I?ll get it fixed right away.”
Ju st then Jessica said,“I knew this would happen when I told you two days ago to get that light fixed.”
So the officer asked for John?s license and after looking at it said,“Sir your license has expired.”
And again John apologized and mentioned that he d idn?t realize that it had expired and would take care of it first thing in the morning.
Jessica said,“I told you a week ago that the state sent you a letter telling you that your license had expired.”
Well by this time,John is a bit upset with his wife contradicting him in front of the officer,and he said in a rather loud voice,“Jessica,will you shut up!”
The officer then leaned over toward Jessica and asked.“Does your husband always talk to you like that?”
Jessica replied,“Only when he?s drunk.”
Three drunks
Two drunks are walking along.One drunk says to the other,“What a beautiful,night,look at the moon.” The other drunk stops and looks at his drunk friend.“You are wrong,that?s not the moon,that?s the sun.”
Both started arguing for a while when they came upon another drunk walking,so they stopped him.“Sir,could you please help settle our argument?Tell us what that thing is up in the sky that?s shining.Is it the moon or the sun?”
The third drunk looked at the sky and then looked at them and said,“Sorry,I don?t live around here.”

第一章算法初步 1．1．1算法的概念 一、教学目标： 1、知识与技能：（1）了解算法的含义，体会算法的思想。（2）能够用自然语言叙述算法。（3）掌握正确的算法应满足的要求。（4）会写出解线性方程（组）的算法。（5）会写出一个求有限整数序列中的最大值的算法。（6）会应用Scilab求解方程组。 2、过程与方法：通过求解二元一次方程组，体会解方程的一般性步骤，从而得到一个解二元一次方程组的步骤，这些步骤就是算法，不同的问题有不同的算法。由于思考问题的角度不同，同一个问题也可能有多个算法，能模仿求解二元一次方程组的步骤，写出一个求有限整数序列中的最大值的算法。 3、情感态度与价值观：通过本节的学习，使我们对计算机的算法语言有一个基本的了解，明确算法的要求，认识到计算机是人类征服自然的一各有力工具，进一步提高探索、认识世界的能力。 二、重点与难点： 重点：算法的含义、解二元一次方程组和判断一个数为质数的算法设计。 难点：把自然语言转化为算法语言。 三、学法与教学用具： 学法：1、写出的算法，必须能解决一类问题(如：判断一个整数n(n>1)是否为质数；求任意一个方程的近似解；……)，并且能够重复使用。 2、要使算法尽量简单、步骤尽量少。 3、要保证算法正确，且计算机能够执行，如：让计算机计算1×2×3×4×5是可以做到的，但让计算机去执行“倒一杯水”“替我理发”等则是做不到的。 教学用具：电脑，计算器，图形计算器 四、教学设想： 1、创设情境： 算法作为一个名词，在中学教科书中并没有出现过，我们在基础教育阶段还没有接触算法概念。但是我们却从小学就开始接触算法，熟悉许多问题的算法。如，做四则运算要先乘除后加减，从里往外脱括弧，竖式笔算等都是算法，至于乘法口诀、珠算口诀更是算法的具体体现。我们知道解一元二次方程的算法，求解一元一次不等式、一元二次不等式的算法，解线性方程组的算法，求两个数的最大公因数的算法等。因此，算法其实是重要的数学对象。 2、探索研究 算法(algorithm)一词源于算术(algorism)，即算术方法，是指一个由已知推求未知的运算过程。后来，人们把它推广到一般，把进行某一工作的方法和步骤称为算法。 广义地说，算法就是做某一件事的步骤或程序。菜谱是做菜肴的算法，洗衣机的使用说明书是操作洗衣机的算法，歌谱是一首歌曲的算法。在数学中，主要研究计算机能实现的算法，即按照某种机械程序步骤一定可以得到结果的解决问题的程序。比如解方程的算法、函数求值的算法、作图的算法，等等。 3、例题分析：
Unit 1 Festivals around the world Ｉ．单元教学目标 II．目标语言
III. 教材分析与教材重组 1. 教材分析 本单元以节日为话题，介绍古今中外节日的种类、由来、意义以及人们的活动和习俗，旨在通过本单元的学习使学生不但了解我国的节日，而且对外国的节日也有所了解，进而拓展社会文化背景、增加跨国文化知识；使学生复习和巩固
运用请求和感谢的表达法，掌握情态动词的用法；并尝试根据阅读的文章写一个不同的结局，能表达自己的观点和想法。 1.1 Warming Up 旨在通过表格引导学生讨论并列举出五个我国节日的日期、庆祝内容和民俗。可以刚刚过去的春节为话题导入对节日的讨论；使他们由自己的经历谈起，扩展到别的节日以及外国的重要节日，激发学生的兴趣，激活他们关于节日的背景知识，为本单元的学习做准备。 1.2 Pre-reading是Reading 的热身活动。主要通过两个问题引导学生思考并讨论自己最喜欢的节日及欢度方式，进而了解学生对节日的认识，以便为阅读作好铺垫。 1.3 Reading 的五篇小短文分别介绍古代节日、亡灵节、纪念名人的节日、丰收节、春天的节日等，使学生了解各种节日的由来及其存在的意义。此部分载有Festivals的重要信息，还呈现了大量的词汇和主要的语法---情态动词的用法。处理时应作为重点、整体处理，通过上下文来教词汇、语法，并引导学生分析长句、难句和复杂句。 1.4 Comprehending是考察对阅读内容的进一步理解。 练习一：六个问题让学生对文章内容有浅层理解并考察课文细节，但又不能仅仅拘泥于课文，要引导学生理解课文内容的基础上联系现实生活。 练习二：要求学生讨论哪些节日是最重要的，哪些是最有趣的，以表格的形式检查学生对所读节日的理解，并训练他们举一反三的归纳和推理能力。 练习三：要求学生找出各种节日共有的三件事，然后讨论为什么这些事对各地的人们都很重要。这就要求学生不仅要温习文章内容而且要结合实际，阐述自己的想法，挖掘学生的思维能力和语言表达能力。 1.5 Learning about Language 分词汇和语法两部分。其中Discovering useful words and expressions是本单元单词的英文释义练习和用文章中的词汇的适当形式填空；Discovering useful structures 是以文章内容为载体在语境中练习语法，掌握情态动词。由此可以看出本教材已明显地由结构为特征的传统语法训练转变到以交际功能为特征的功能语法训练，充分体现了新教材话题、功能、结构相结合的特点。 1.6 Using Language 是英语听说读写的全面运用的练习。
《导数的概念及几何意义》教学设计 教材内容分析 本节课的教学内容选自人教社普通高中课程标准实验教科书（ A 版）数学选修2－2第一章第一节的《变化率与导数》，《导数的概念及几何意义》是在学习了函数平均变化率以后，过渡到瞬时变化率，从而得出导数的概念，再从平均变化率的几何意义，迁移至瞬时变化率即导数的几何意义。 导数是微积分的核心概念之一，是从生产技术和自然科学的需要中产生的，它深刻揭示了函数变化的本质，其思想方法和基本理论在在天文、物理、工程技术中有着广泛的应用，而且在日常生活及经济领域也日渐显示出其重要的功能。 在中学数学中，导数具有相当重要的地位和作用。 从横向看，导数在现行高中教材体系中处于一种特殊的地位。它是众多知识的交汇点，是解决函数、不等式、数列、几何等多章节相关问题的重要工具， 它以更高的观点和更简捷的方法对中学数学的许多问题起到以简驭繁的处理。 从纵向看，导数是函数一章学习的延续和深化，也是对极限知识的发展， 同时为后继研究导数的几何意义及应用打下必备的基础， 具有承前启后的重要作用。 学生学情分析 学生在高一年级的物理课程中已经学习了瞬时速度，因此，先通过求物体在某一时刻的平均速度的极限去得出瞬时速度， 再由此抽象出函数在某点的平均变化率的极限就是瞬时变化率的的模型， 并将瞬时变化率定义为导数，这是符合学生认知规律的． 而在第一课时平均变化率的学习中，课本给出了一个思考，观察函数 )(x f y 的图像，平均变化x y 表示什么？这个思考为研究导数的几何意义埋下 了伏笔。因此，在将瞬时变化率定义为导数之后， 立即让学生继续探索导数的几何意义，学生会对导数的几何意义有更为深刻的认识。 教学目标 1、知识与技能目标会从数值逼近、几何直观感知，解析式抽象三个角度认识导数的含义，应用导数的定义求简单函数在某点处的导数， 掌握求导数的基本步骤，初步学会求解 简单函数在一点处的切线方程。 2、过程与方法目标 通过动手计算培养学生观察、分析、比较和归纳能力，通过问题的探究体会逼近、类比、以及用已知探求未知、从特殊到一般的数学思想方法。 3、情感态度与价值观

One spring day the wind brought a 3 (pride) little seed and dropped it at the root of the tree. Soon it grew into a plant. “I’ll climb to the top of the tree,” said 4 little plant. “They’ll see how quickly I can grow.” So it held tightly to the tree and climbed 5 it was up to the top branch. It said to the tree, ”You have grown for a great many years, and I only 6 (begin) this summer and see where I have come to. ” But the old tree just said 7 at all. After a while a great storm
普通高中课程标准实验教科书（人教版） 英语必修Ⅲ Unit1 Festivals around the world (Reading) Festivals and Celebrations 学生姓名：赵倩倩
Unit 1Festivals around the world Ⅰ.Analysis of teaching material At the beginning of the class, the teacher can lead in the topic of the unit by having a free talk with students about their winter holidays and the Spring Festival. The Warming Up is intended to have students start thinking about the variety of events and festivals that are celebrated in China, and connect them with seasons of the year and reasons for the celebrations. The teacher can use this part to introduce information that Chinese students should have about their country’s cultural events. The Pre-reading is a continuation of the Warming Up and it moves the discussion to a more personal level. It is intended to help students enter imaginatively into a discussion of festivals and their importance to the society. It also directs their attention to the variety of events and activities those festivals include. The teacher should let students discuss the questions and predict what kind of information will be introduced in the Reading. The reading passage titled FESTIV ALS AND CELEBRATIONS briefly describes the earliest kinds of festivals with the reasons for them, and then four different kinds of festivals that occur in most parts of the world. Encourage students to look at the pictures and the heading of each section to guess what the text might be about. Then let them skim for the general idea for each section, and scan for further understanding. Because this passage introduces a lot of useful new words and expressions which are only used for festivals, in order not to let students feel much difficult, the teacher should deal with any language problems while they are reading. After reading, students are required to do the four exercises in the Comprehending to see how much they have understood the reading passage. The teacher can first let them work in pairs or in groups to find the answers cooperatively, and then check their answers with the whole class. To consolidate the contents of the reading passage, students should be required to talk about festivals in their own words at the end of the class. In order to arouse students’ interest, the teacher can hold a competition between groups. Ⅱ.Teaching aims 1.Knowledge aims 1). Get students to learn the useful new words and expressions in this part: beauty, harvest, starve, origin, religious, ancestor, Mexico, feast, bone, belief, poet, arrival, gain, independence, gather, agriculture, award, rooster, admire, energetic, Easter, clothing, Christian, custom, take place, in memory of, dress up, play a trick on, look forward to, day and night, as though, have fun with 2). Let students learn about history and basic knowledge of festivals both in and out of China. 2.Ability aims 1). Develop students’ reading ability and let them learn different reading skills.
对数函数及其性质（1） 一、教材分析 本小节选自《普通高中课程标准数学教科书-数学必修（一）》（人教版）第二章基本初等函数（1）2.2.2对数函数及其性质（第一课时），主要内容是学习对数函数的定义、图象、性质及初步应用。对数函数是继指数函数之后的又一个重要初等函数，无论从知识或思想方法的角度对数函数与指数函数都有许多类似之处。与指数函数相比，对数函数所涉及的知识更丰富、方法更灵活，能力要求也更高。学习对数函数是对指数函数知识和方法的巩固、深化和提高，也为解决函数综合问题及其在实际上的应用奠定良好的基础。虽然这个内容十分熟悉，但新教材做了一定的改动，如何设计能够符合新课标理念，是人们十分关注的，正因如此，本人选择这课题立求某些方面有所突破。 二、学生学习情况分析 刚从初中升入高一的学生，仍保留着初中生许多学习特点，能力发展正处于形象思维向抽象思维转折阶段，但更注重形象思维。由于函数概念十分抽象，又以对数运算为基础，同时，初中函数教学要求降低，初中生运算能力有所下降，这双重问题增加了对数函数教学的难度。教师必须认识到这一点，教学中要控制要求的拔高，关注学习过程。 三、设计理念 本节课以建构主义基本理论为指导，以新课标基本理念为依据进行设计的，针对学生的学习背景，对数函数的教学首先要挖掘其知识背景贴近学生实际，其次，激发学生的学习热情，把学习的主动权交给学生，为他们提供自主探究、合作交流的机会，确实改变学生的学习方式。 四、教学目标 1．通过具体实例，直观了解对数函数模型所刻画的数量关系，初步理解对数函数的概念，体会对数函数是一类重要的函数模型； 2．能借助计算器或计算机画出具体对数函数的图象，探索并了解对数函数的单调性与特殊点； 3．通过比较、对照的方法，引导学生结合图象类比指数函数，探索研究对数函数的性质，培养学生运用函数的观点解决实际问题。 五、教学重点与难点 重点是掌握对数函数的图象和性质，难点是底数对对数函数值变化的影响． 六、教学过程设计
第1，2课时1.1．1 任意角 教学目标 （一） 知识与技能目标 理解任意角的概念(包括正角、负角、零角) 与区间角的概念. （二） 过程与能力目标 会建立直角坐标系讨论任意角,能判断象限角,会书写终边相同角的集合；掌握区间角的集合的书写． （三） 情感与态度目标 1． 提高学生的推理能力； 2．培养学生应用意识． 教学重点：任意角概念的理解；区间角的集合的书写． 教学难点：终边相同角的集合的表示；区间角的集合的书写． 教学过程 一、引入： 1．回顾角的定义 ①角的第一种定义是有公共端点的两条射线组成的图形叫做角. ②角的第二种定义是角可以看成平面内一条射线绕着端点从一个位置旋转到另一个位置所形成的图形． 二、新课： 1．角的有关概念： ①角的定义： 角可以看成平面内一条射线绕着端点从一个位置旋转到另一个位置所形成的图形． ②角的名称： ③角的分类： ④注意： ⑴在不引起混淆的情况下，“角α ”或“∠α ”可以简化成“α ”； ⑵零角的终边与始边重合，如果α是零角α =0°； ⑶角的概念经过推广后，已包括正角、负角和零角． ⑤练习：请说出角α、β、γ各是多少度? 2．象限角的概念： ①定义：若将角顶点与原点重合，角的始边与x 轴的非负半轴重合，那么 正角：按逆时针方向旋转形成的角 零角：射线没有任何旋转形成的角 始 边 终 边 顶 点 A O B 负角：按顺时针方向旋转形成的角
角的终边(端点除外)在第几象限，我们就说这个角是第几象限角． 例1．如图⑴⑵中的角分别属于第几象限角？ 例2．在直角坐标系中，作出下列各角，并指出它们是第几象限的角． ⑴ 60°； ⑵ 120°； ⑶ 240°； ⑷ 300°； ⑸ 420°； ⑹ 480°； 答：分别为1、2、3、4、1、2象限角． 3．探究： 终边相同的角的表示： 所有与角α终边相同的角，连同α在内，可构成一个集合S ＝{β|β=α+k ·360°，k ∈Z}，即任一与角α终边相同的角，都可以表示成角α与整个周角的和． 注意： ⑴ k ∈Z ⑵ α是任一角； ⑶ 终边相同的角不一定相等，但相等的角终边一定相同．终边相同的角有无限个，它们相差 360°的整数倍； ⑷ 角α + k ·720 °与角α终边相同，但不能表示与角α终边相同的所有角． 例3．在0°到360°范围内，找出与下列各角终边相等的角，并判断它们是第几象限角． ⑴－120°；⑵640 °；⑶－950°12＇． 答：⑴240°,第三象限角；⑵280°,第四象限角；⑶129°48＇,第二象限角； 例4．写出终边在y 轴上的角的集合(用0°到360°的角表示) ． 解:{α | α = 90°+ n ·180°,n ∈Z}． 例5．写出终边在x y 上的角的集合S,并把S 中适合不等式－360°≤β＜720°的元素β写出来． 4．课堂小结 ①角的定义； ②角的分类： ⑵ B 1 y ⑴ O x 45° B 2 O x B 3 y 30° 60o

(回归课本P33) Canada is a multicultural country. 加拿大是一个多元文化国家。[归纳拓展] multiply a.乘;繁殖(multi + ply表动词→变多→乘) multiple a.多样的;多功能的(multi + pile→多的→多功能的) multilingual a. 多种语言的(multi + lingual方向的) multidirectional a. 多方向的(multi + directional方向的) multiform a.多种多样的(multi + form形式) multicultural a.多种文化的(multi + cultural文化的) multimedia a.多媒体的(multi + media媒介) multitude a.多数;群众(multi + tude状态→多的状态→多数) rather than并列连词，而不是 (回归课本P34) Rather than take the aero plane all the way, they decided to fly to Vancouver and then take the train from west to east across Canada. 他们不想一路乘飞机，而决定先飞到温哥华，再从西海岸乘火车横穿加拿大到东海岸。 1、rather than:意为“而不是”、“而没有”，侧重客观上的差别，还可以表示“与其……，倒不如（或宁可）……”，侧重句子主语或说话人主观上的选择。句中rather than 前后一般应为名词、代词、动名词、形容词、谓语动词、动词不定式、介词短语，甚至分句等。 2、rather than做并列连词。其前后都应是相互对应的词语，但接不定式时，常可省去不定式符号to 。rather than 也可分开使用，和would 或had 构成
《§3.4.1基本不等式》的教学设计 教材：人教版高中数学必修5第三章 一、教学内容解析 本节选自人教版必修五的第三章第四节的第一课时，它是在学生学习完“不等式的性质”、“一元二次不等式及其解法”及“二元一次不等式（组）与简单的线性规划问题”的基础上对不等式的进一步研究。在探究基本不等式内涵和证明的过程中，能够培养学生观察问题、分析问题和解决问题的能力；培养学生形成数形结合的思想意识；在应用的过程中，通过对条件的转换和变式，有助于培养学生形成类比归纳的思想和习惯，进而形成严谨的思维方式。 二、教学目标设置 1．通过探究“数学家大会的会标”及感受会标的变形，引导学生从几何图形中获得两个基本不等式，了解基本不等式的几何背景培养学生观察问题、分析问题和解决问题的能力；培养学生形成数形结合的思想意识； 2．进一步让学生探究不等式的代数证明，加深对基本不等式的理解和认识，提高学生逻辑推理的能力和严谨的思维方式。 3．通过例题让学生学会用基本不等式求最大值和最小值。 三、学生学情分析 对于高一的学生，不等式并不陌生，前面学习了不等式及不等式的性质，能够进行简单的数与式的比较，本节所学内容就用到了不等式的性质，所以学生可以在巩固不等式性质的前提下学习基本不等式，接受上是容易的，争取让学生真正意义上理解基本不等式。 四、教学策略分析 在教学过程中学生往往会直接应用不等式而忽略成立的条件，因此本节课的重点内容是对基本不等式的理解和运用。在运用过程中生成的规律，在学生做题时能灵活运用是难点，因此理解基本不等式和灵活应用基本不等式十本节课难点 五、教学过程： （一）情景引入 下图是2002年在北京召开的第24届国际数学家大会会议现场。
