高中英语(人教大纲)第三册：Unit4 Green world第一课时教案

Unit 4 Green worldsⅠ.Brief Statements Based on the UnitThere are a variety of plants.How should we classify them scientifically?Who is the first to do this?We can find the answers in Unit 4.The unit begins with talking about four different kinds of flowers—tulip,rose,sunflower and peony.The students are asked to give the names and tell the places they e from as well as what they are used for,etc.In Speaking Part,the students are given different topics to talk about.First they are asked to describe how to plant soybeans.Five pictures are given to show the whole process of growing soybeans.Even though you haven’t done this by yourself,you’ll have some ideas.As long as you’ve heard of such things as this,you can describe it without much difficulty.Then they are asked to talk about how to plant vegetables on condition that you have a small garden.If you can’t do this successfully,you can choose a much easier topic—describe the process of planting and growth of any plant which you are familiar with.In a happy and relaxed atmosphere,the students’ability to speak English is improved.Listening asks the students to listen to a material about fruit and how to group different kinds of fruit.Besides,the material gives the reason why we eat fruit.The story about Captain Cook and his soldiers is also interesting and instructive.The teacher should ask the students to listen carefully so as to improve their listening ability.The author of the text describes three world famous scientists—Carl Linnaeus,Daniel Solander and Joseph Banks.They gave birth to a science—botany,or rather,Carl Linnaeus gave birth to it and the other two enriched it greatly.After they go through the whole article,the students will have improved their reading ability.At the same time,they’ll be struck by the scientists’ spirit of devotion as well as learn more about the science—botany.In order to help the students to learn and master the useful words and expressions,exercises of different forms are designed in Word Study.The students can use these words and expressions in different situations.In Grammar,the students will review the Object.A lot of examples are given to let the students see their usages—what can be used as the object,a useful sentence pattern:have something done,and direct and indirect object.The students will know the grammar item further after they have done allthe exercises.In Reading,Intergrating Skills,another three scientists Charles Darwin,Gregor Mendel and Gote Turesson and their great scientific achievements are shown to the students.After learning the passage,the students will learn the same as they did from the text before.Writing is designed perfectly.In general,writing is hard to most students,expecially English writing.However,when doing the part,the students will perhaps feel different,as detailed information is given to them.How to apply the different information when they are writing is an ability we should pay attention to.If this can be done successfully,the students’ writing ability will be further improved.Ⅱ.Teaching Goals1.Talk about botany.2.Speak about procedures.3.Review the Object.4.Write a description of plants.Ⅲ.Background InformationThe Scientific AttitudeWhat is the nature of the scientific attitude,the attitude of the man or woman who studies and applied physics,biology,chemistry,geology,engineering,medicine or any other science?We all know that science plays an important role in the societies in which we live.Many people believe,however,that our progress depends on two different aspects of science.The first of these is the application of the machines,products and systems of applied knowledge that scientists and technologists ually aided by technology,science improves the structure of society and helps man to gain increasing control over his environment.New fibers and drugs,faster and safer means of transportation,new systems of applied knowledge are some examples of this aspect of science.The second aspect is the application by all members of society,from the government official to the ordinary citizen,of the special methods of thought and action that scientists use in their work.What are these special methods of thinking and acting?First of all,it seems that a successful scientist is full of curiosity—he wants to find out how and why the universe works.He usually directs his attention towards problems which he notices have no satisfactory explanation,and his curiosity makes him look for underlying relationships even if the data available seem to be unconnected.Moreover,he thinks he can improve the existing conditions,whether of pure or applied knowledge,and enjoys trying to solve the problems which this involves.He is a good observer,accurate,patient and objective and applies persistent and logical thought to the observations he makes.He utilizes the facts he observes to the fullest extent.For example,trained observers obtain a very large amount of information about a star mainly from the accurate analysis of the simple lines that appear in a spectrum.He is skeptical—he does not accept statements which are not based on the most plete evidence available—and therefore rejects authority as the sole basis for truth.Scientists always check statements and make experiments carefully and objectively to verify them.Lastly,he is highly imaginative since he often has to look for relationships in data which are not only plex but also frequently inplete.Furthermore,he needs imagination if he wants to make hypotheses of how processes work and how events take place.Ⅳ.Teaching Time:Five periodsThe First PeriodTeaching Aims:1.Get the students to talk about botany—four different kinds of flowers to train the students to learn how to make a description.2.Get the students to listen to a material to train their listening ability.3.Get the students to talk about procedures.Teaching Important Points:1.Improve the students’ speaking ability by describing flowers.2.Improve the students’ listening ability.Teaching Difficult Point:How to talk about procedures—how to describe something orderly.Teaching Methods:1.Talking method to make the students speak about what they want to say.2.Discussion method to give every student a chance to speak.3.Pair work or group work to make every student active.Teaching Aids:1.a puter2.a courseware3.a tape recorderTeaching Procedures:Step Ⅰ GreetingsT:Good morning,everyone!Ss:Good morning,teacher.T:Sit down,please.Step Ⅱ Warming Up(Teacher and students learn the new words of this period together.)T:Do you like flowers?Ss:Yes,very much.T:Now I’ll show you four pictures of different flowers.(Teacher shows the pictures on the screen.)(1)(2)(3)(4)T:Look at the pictures and tell us their names,please.Who know the first flowers?S a:They are peonies.S b:The second are roses and the third are tulips.S c:The last ones are sunflowers.T:Can you tell us something about each kind of flowers?Such as the place it es from,its use and something else.S D:I’’re beautiful.All of us like them very much.S E:I saw an article in the newspaper.It says that sunflowers e from North America,Indians there began to grow them some 3000 years ago.Their seeds can be eaten and their flowers can be viewed and admired.It is said that they can be used as medicine,too.S F:We can make cooking oil out of their seeds.The sunflower is out of the four important oil-bearing crops.The others are soybeans,peanuts and rapeseeds.S G:I went to see peonies last year in Luoyang.They are the most beautiful flowers I’ve everseen.There were so many that we found that our eyes could not take them all in at a time.The guider told us that there are 960 types of peonies in Luogang and hundreds of thousands of people e here to view and admire them every year.S H:The tulip is a kind of garden plant growing from a bulb in spring,with a large brightly-colored cup-flower on a tall stem.Tulips are beautiful flowers and people often send them to their friends as presents.Tulips in the Netherlands are the most famous all over the world.S I:Every year large quantities of tulips are exported from the Netherlands into the US,German and Japan.So a lot of money is made by the Dutch.T:Who can tell us something about roses?Which kind of flower is your favourite?S J:I like roses best,which are the best presents to be sent to our friends.It is also very popular to send roses as love signal between young people.S K:Red roses indicate Warmth and love and white roses,purity and simplicity.Blue roses are a sign of honesty and sincereness.If my best friend has a new job in another place,I’ll send him thirteen roses,expressing that our friendship will last forever.T:Thank you very much for giving us so much about flowers.Flowers can make our world beautiful and colorful,increase friendship between us and have an effect which anything else can’t have.I hope some of you can bee experts in raising flowers.Next,we’ll do listening.Step Ⅲ ListeningT:Please turn to Page 28.Before listening,we should go over the requirements.Please read the questions on Pages 28 and 29 and see what we should do after we finish listening to the material.(A few minutes later.)T:Have you finished?Ss:Yes.T:I’’ll play it three times.When I play it for the first time,please do as much of the exercise as you can.Then I’ll play it for the second time.This time,pay your attention to the parts unfinished.After that,you can have a discussion and check your answers with your partner.Next,let’s check theanswers together.At last,you’ll have a chance to listen to the material once again.Are you clear about this?(Ss:Yes.)Let’s begin.Step Ⅳ SpeakingT:Growing plants in pots or boxes at home can be both fun and a useful experience.When we give our friends presents such as flowers or pot plants,we often tell them how to grow and take care of them.Besides,growing plants can also get us to learn some knowledge which we can’t learn from books.It can make us value what the labouring people create.What did you ever plant and where did you plant them?S a:I’m a student from the countryside.I see my parents work in the field and green houses,planting crops as well as tomatoes,pumpkins,sunflowers and strawberries.In the summer vacation,I often do farmwork with them in the field.S b:I live in town.We have a small garden behind our house.Every year we plant some flowers and some vegetables,such as tomatoes,cucumbers,eggplants and beans.S c:I live in a building.Our apartment has a big balcony and on both sides of it we plant some flowers and vegetables,such as tomatoes and cucumbers.T:Who has ever planted soybeans plant?S d and Se:We did.T:The pictures below show the stages of growing soybeans.Can you describe how to grow and take care of the soy bean plant?S d:Yes.First you should put some rich soil in a big pot or you can bring some soil from a field and then mix it with some powder,which is made from fish,blood and bones.Then put some seeds in it.The seeds should be big and round,chosen from the best seed-heads.Besides,the seeds should not be too shallow or too deep in the soil,two or three centimetres in general.S e:You should put the pot in a warm place.Water it every now and then.After a few days the young plants will e out.Be sure to keep the pot wet enough.When they are about three or four inches tall,put less water so that the roots of the young plants can grow deeper.Thus you’ll have big and strong plants.S f:During the growing period of the plants you should put fertilizer twice or third in the soil.At last in the autumn you’’s more,you should put up the seeds whenever possible.Good seeds,rich soil,plenty of sunlight and enough water are necessary for any plant.T:Do you want to have a small garden?Ss:Yes,we do.T:Which plants,vegetables or flowers would you grow if you have one?When to take care of them and when to harvest or pick them?S g’’ll give them enough water and fertilizer and remove the seeds whenever there are some.When it is in late July,I’m sure I can get in good and ripe tomatoes.T:You give us a vivid picture of planting tomatoes.I think you are all sure to do the job well if you have a small garden.That experience must have a lot of fun.Step Ⅴ Summary and HomeworkT:In this class,we’ve talked about some flowers,done the listening and practiced describing how to plant some vegetables.What vocabulary will you need to talk about flowers and plants?How to talk about a procedure?S1:We use such words:words expressing different colors:red,yellow,blue,black,orange,purple,gray,etc.S2:Words like strong,weak,big,tall,beautiful,pretty,colourful,etc.S3:Brightly,coloured,cup-shaped and love,warmth,purity and simplicity.S4:Honestly and sincereness.S5:When we describe a procedure,we can describe it like this:First;first of all...;you should do...first;then...;and then...;at last...;finally....(Teacher writes the words above on the blackboard.)T:Now today’s homework:Do Exercise3 on Page 30.Have a talk with your partner.Next class we’’s all for this class.Step Ⅵ The Design of the Writing on the BlackboardUnit 4Green worldsThe First PeriodWords used to describe flowers:1.Words expressing

“热身” （Warming up）部分的话题是“花” ，教材展示的四幅不同种类的花的图片，并设计了四个问题，1.是否认识这四种花，能否用英语说出这些花的名称；2.是否知道有关这四种花的知识，如：这些花一般生长在哪里，都有哪些用途；3.讨论自己最喜欢的花，并解释为什么，因为大部分的花都有自己的特性及象征意义；4.谈论花草所需要的词汇。

“听力” （Listening）部分的话题是“水果” 。

内容分为：1.听前任务——讨论话题：你知道哪些种类的水果？你能将水果归类吗？为什么人们必须吃水果？这样的设计为听力起了热身作用，为下文的听力作了铺垫。

2.听力任务——完成听力和相关练习。

“口语” （Speaking）部分共设计了三个内容。

1.西红柿、南瓜、向日葵和草莓等都很适合种植于花盆。

课文用四幅图片向学生展示了如何利用花盆种植大豆的步骤，请学生仔细观察图片，然后解释如何种植和照料大豆的生长过程。

2. 小组活动。

假设你有一个小花园，你可以种值任何你喜欢的植物。

请讨论“你将计划种植何种植物（蔬菜、花等），如何照料、何时收获” 。

3. 以花束为载体，描述如何养护花束，进一步训练学生如何表达做事步骤。

“阅读” （Reading）部分主要介绍植物学科的发展历史。

18 世纪以前，植物的归类问题一直被医生们研究，直到卡尔·林尼厄斯对植物分类做出突破性贡献，他以家族来归类植物的体系学说征服了整个世界。

接着，卡尔·林尼厄斯的学生丹尼尔·索兰德又对老师的归类体系做了进一步的改进。

丹尼尔· 索兰德的朋友约瑟夫· 班克斯后来邀请他参加了 “奋力号” 船的大洋州远征。

此次远航的目的有三个，其中一个为记载、归类和描述旅途中所观察到的所有动物和植物。

班克斯自费参加了这次三年的航行旅途，硕果累累。

他们不但研究和描述新发现的植物，而且还发现了具有经济价值的农作物。

班克斯是第一个大规模地将农作物从一个洲移到另一个洲的人，帮助并促进了本土经济的发展。

回来以后，班克斯帮助发展了皇家植物园，并使之成为科学和经济研究中心。

“读后” （Post-reading）设计了两类练习，单选和回答问题。

检测学生对阅读内容细节的理解、推测和总结，引导学生如何阅读，启发学生思维。

“语言学习” （Language study）分为词汇学习和语法两部分。

词汇学习（Word study）设计了两个练习。

第一个练习要求学生根据句中划线的单词找出近义词，帮助学生更好地掌握新单词，第二个练习要求从课文中找出单词填入划线部分，帮助学生巩固所学词汇，并能在不同语境中运用。

语法（Grammar）是复习宾语。

教材设计了三个练习。

第一个练习要求学生找出句中的宾语，并指出是哪一类词、短语、从句充当宾语。

第二个练习要求学生自己提供不同形式的宾语完成句子，第三个练习则是关于直接宾语和间接宾语的练习。

“综合技能” （Integrating skills）部分包括阅读和写作。

阅读部分介绍了达尔文和其他科学家关于物种所作的努力；并设计了两个练习；第一个练习属于阅读细节的理解，即文章介绍的三个科学家在植物方面的新发现和研究结果；第二个练习讨论 2000 年前，人们就已了解土壤条件对农作物产量的影响，为什么说杜尔松的发现对农业还是非常重要的。

写作要求学生先研究图中的植物——蒲公英，它们看起来生长于不同地方，一个生长在又热又干燥，而另一个生长在又冷又潮湿的地方；然后描述这两种蒲公英的不同之处，并利用所学知识解释其原因。

书本还提供了写作提纲，有利于学生对一种植物的描述。

“学习建议” （Tips）介绍了如何仔细观察事物并准确地记录、描述植物及其重要性。

“复习要点” （Checkpoint）部分帮助学生简要小结了宾语，同时让学生罗列一些在植物学和农业领域描述步骤所需的词汇，以达到复习巩固的目的。

（修饰形容词） You don’t have to be angry. He merely wanted to know the truth. 你不必太生气了，他只不过是想知道点事实真相。

（修饰动词） ⇒ 同义比较： scarcely adv. 几乎不，简直没有 eg. We scarcely ever used the reserve generator. 我们几乎从未用过这台备用发动机。

They could scarcely complain after such good treatment. 在受到如此好的待遇后他们绝不会抱怨。

scarcely 有否定的意味，表示“不足地，不充分地，几乎没有” ，因此当它与另一否定形式一起用时被认为是不正确的，比如在 I couldn’t scarcely believe it 中。

⇒ group, company, party, band 这组名词表示“组”“群”“帮”或“伙” 、、。
