【精品】高中英语(人教大纲)第二册下：Unit13 The water planet(第一课时)
Unit 13 The water planetⅠ.Brief Statements Based on the UnitAs we all know,the earth is an ocean planet and 99% percent of the living space on earth is in the oceans.It is water that makes the ocean such a great place to live in.This unit mainly deals with the properties of water and how the properties of water make the ocean become so important.We learn this unit to help students not only know about the properties of water,but also learn how to use water in a good way.Besides,we learn this unit to let students realize the importance of protecting water.Of course,it is necessary for students to master the important phrases and sentences in the unit.Meanwhile we should review some important usage of Modal Verbs.Ⅱ.Teaching Goals1.Talk about water and the ocean.2.Practise communicative skills.3.Review Modal Verbs.4.Write an explanation paragraph.Ⅲ.Background Information1.What Lies under the Blue Water?Just like the houses we live in,the ocean has several “floors”or layers.Different fish live on different layers and are neighbours,though not always friendly ones!The ocean’s top layer is the sunlit zone(透光层).It goes down to around 200 meters below water.This layer is warm and bright.It is also home to most plants and fish.Many fish in this layer are streamlined,so they can quickly swim from danger and catch food.The twilight zone(弱光层) is the next layer and is from about 200 to 600 meters below water.Almost no plants grow here.Many animals in this zone swim up to the surface at night to feed,and move into deeper waters during the day.They also eat each other,so many of them have sharp teeth and very big mouths.Many fish in this zone don’t have a streamlined body because they lie and wait for prey to come to them.Below the twilight layer is the midnight zone(无光层).It is from 600 meters to the bottom of the sea.The water is cold and completely dark.No plants live here but many small animals can.Many animals in the twilight and midnight zones produce their own lights.The angler-fish(琵琶鱼) is one of them.It has a beautiful light on its head to attract prey!Maybe you have seen one of the coolest films Finding Nemo(《海底总动员》).Do you remember Marlin,Nemo’s father,“borrowed”light to help Dory read?That wasn’t a flashlight,it was a fish!They also use light to frighten enemies and to “talk”with each other.2.WaterA family of six needs over 20 gallons of water a day,just for basic drinking,cooking and keeping clean;but only one in three of the world’s households has a water supply in the home.Most others get their water from rivers,lakes springs or holes in the ground,or,in town,from stand-pipes shared with hundreds of other families.Throughout the world’s poorest countries women damage their health and lose hours of every day carrying huge containers of water—up to 44 lbs in weight—often from sources several miles away.All too frequently they bring home sickness or death,as well as water.Untreated water,which may have come from a muddy hole shared with cattle,can be lethal,especially for young children.To sink a well or pipe water from a natural spring,and maintain the system afterwards,people need access to land with a water source,to capital,equipment and technical know-how.In towns they may need to lobby the local water authority to repair or extend existing systems.Water is precious,and access to it gives power—to landowners with wells on their land,or to country controlling major international rivers.The demands on the earth’s water resources are growing rapidly,partly as a result of population growth,but even more because industry now uses such huge quantities—it takes 100 000 gallons to produce a car.Ⅳ.Teaching Time:Five periodsThe First PeriodTeaching Aims:1.Learn and master the new words and the useful expressions of this part.Words:cube,sailor,disadvantages,entertainmentPhrases:come up with,happen toUseful expressions:The water is being used to/for…We should/could…If we…we can…It would be better…2.Learn something about water by doing experiment.3.Do some listening.4.Improve the students’ speaking ability by talking.Teaching Important Points:1.Make the students be free to talk about water.2.Improve the students’ listening ability by listening.Teaching Difficult Points:1.How to finish the task of speaking.2.How to improve the students’ listening ability.Teaching Methods:1.Listening-and-answering activity to help the students go through with the listening material.2.Individual,pair or group work to make every student work in class.Teaching Aids:1.the multimedia2.the blackboard3.an empty glass,a bottle of water and a bottle of vegetable oilTeaching Procedures:Step ⅠGreetings and Lead-inT:Hello,everyone.Ss:Hello,teacher.T:Attention,please.As we all know,every year during the Spring Festival and Lantern Festival in our country,people like to see the lion dance and guess the riddles.Do you like to guess the riddle,then?Ss:Yes.T:OK.Now I have a riddle.Please guess it.T:What’s it?Ss:It’s very easy.It’s water.T:Yeah,today we will talk about water.Now please tell me what you know about water.S1:Water is used to drink.S2:Water can be used to water the flowers.S3:I think water can be used to make electricity.Step ⅡWarming upT:Thank you for your ideas.Next we will make some interesting experiments.Maybe you can learn more about water from the following experiments.Li Lei,would you like to come here to help me?S4:I’d love to.T:Now,look at Li Lei and me.We will begin.You should watch the experiment carefully and try to tell me what happens and why.(Teacher puts a bottle of water,a bottle of vegetable oil and an empty glass on the desk.)T:Li Lei,pour some water and some vegetable oil into the empty glass.Other students,please watch carefully.(A few seconds later.)Ss:Fantastic!The liquid in the glass has become two parts.T:Try to describe it in detail.S5:Let me try.The part above is vegetable oil and the part below is water.But I don’t know why.T:Good question.Who’d like to answer his question?(Nobody answers his question.)T:Perhaps it is a little difficult to answer it immediately.Now you can have a discussion about the reason for it,using what you have learnt in physics.(Teacher lets students discuss in groups of four.A few minutes later,teacher checks their answers.)T:Who wants to explain the phenomenon?S6:I think water is heavier than oil,so vegetable oil is on the top of the water.T:Who has different ideas?S7:I think we should say that the density of water is higher than the density of vegetable oil,so the result formed.S8:What’s the meaning of “density”?S9:“Density”is “密度”in Chinese.T:Do you agree with the reason for it?Ss:Yes.We agree with the idea.T:As we know,if we pour milk and water into one glass,we can’t tell where water is and where milk is.But just now we poured oil and water into one glass,it is so different now.Do you know why?Ss:Because oil can’t dissolve in water,but milk can.T:Very good.Let’s make a summary about the experiment.If we pour vegetable oil and water into one glass,the liquid will become two parts because oil can’t dissolve in water.Since the density of water is higher than vegetable oil,vegetable oil will be on top of the water.Is that clear?Ss:Yes.T:Would you like to watch another experiment?Ss:I’d love to.T:OK.I’ll perform the next experiment by myself.Look at me.I have a glass of water.Now I’ll cover it with a piece of thick paper.Attention,please.(Teacher puts one hand on the paper and turns the glass upside down.Then teacher slowly takes his/her hand away from the paper.)T:What can you see?Ss:The piece of paper doesn’t fall and the water in the glass doesn’t flow.T:Yes.You are right.Now you are given a few minutes to have a discussion about the reason for it.(Teacher gives students a few minutes to discuss,and then checks their answers.)T:Who can tell us the reason why the piece of paper doesn’t fall and the water doesn’t flow?S10:I want to have a try.When the glass of water covered with a piece of paper is turned upside down,the pressure from air to the piece of paper is bigger than the pressure from the water in the glass to the piece of paper.So the paper won’t fall and the water won’t flow.T:Excellent!Thank you for your explanation.I am very glad to see that you are all interested in making experiments.After class,you can carry out another two experiments on Page 17.When you perform them,try to describe what happens and why.OK?Ss:OK.T:Now,let’s look at a picture.(Teacher shows a picture on the screen.)T:What can you see?Ss:There is a river in the picture,but it’s very dirty.T:Anything else?S11:There are some plastic bags and empty tins on the surface of the river.T:Yes.We all know water is important to human beings and all the animals and plants.Unfortunately water is being polluted now.What do you think we can do to protect the water on our planet?(Teacher gives students enough time to prepare.When they prepare,teacher goes among the students to help them to express their ideas correctly.)Sample answer:To protect the water on our planet,I think we should save every drop of water and stop throwing rubbish into water.Besides,we should try our best to help the people around us realize the importance of using and protecting our water.Step ⅢListeningT:Next,let’s do some listening.Turn to Page 18 and look at the Listening part.You can listen to the famous poems about life on the ocean.Listen carefully and write down some key wordsT:Now listen,please.(Teacher plays the tape for the first time.Then play it for the second time.During this time,teacher may pause for students to write down the information.Play some parts of the tape one more time if necessary.Finally teacher checks the answers with the whole class.) Step ⅣSpeakingT:In our daily life,water can be used in different ways.Now we’ll talk about the ways in which water can be used.Look at the pictures on Page 18.The six pictures mean six different ways to use water.You can choose one of the pictures to discuss the importance of using and protecting our water,and then try to use some sentences to describe the picture you choose.If you like,you can make a dialogue with your partner about the picture.When you discuss,you may use the questions(Teacher shows the questions on the screen by multimedia and gives students enough time to discuss and prepare.)Suggested answers:(Picture 1)We can use water to make electricity,which can give us light and make us feel warm.I think it is a good way to use water.(Picture 3) Water has a lot of usages and home use is the commonest one.Every day we must drink enough water.In addition,we need a lot of water,just for cooking and keeping clean.Water can help us to keep healthy.But if the waste water from home use is poured into river and soil,itwill be harmful for some animals and plants.So we must pay more attention to it.(Picture 4) In Picture 4,water is being used in industry.Water is very important to industry.It can be used to make paper,cool machine and so on.But the disadvantage is that a lot of water mixed with some poisonous things being poured into the river and the sea.It is dangerous for the living things in the water.(Picture 6)A:Do you know how the water is being used in Picture 6?B:Water is being used for entertainment.A:Is it a good way to use water?B:Yes,because it can help people keep fit and enjoy nature.But if people throw rubbish into the water,it will be bad for us.A:Yes.It is the disadvantage of using water in this way.We must be careful.Step ⅤSummary and HomeworkT:Today,we’re mainly learned something about water by doing experiments,speaking and listening.Besides,we’ve learnt some new words and phrases,such as:happen to,come up with,density,…After class,try to remember them and preview the next part—Reading part.That’s all for today.Goodbye,everyone.Ss:Goodbye,teacher!Step ⅦRecord after Teaching。

高中英语 语法精讲(Unit 13 The water planet)大纲人教版第二册
语法精讲情态动词情态动词是动词的一种，顾名思义，表示说话人的情感或态度，认为“可能/应当/必要〞，或表达“怀疑/命令/许可〞等。
情态动词没有人称和数的变化。
情态动词本身词义不全，不能单独作谓语，必须和动词原形连用，共同构成谓语动词。
有些情态动词有过去式，有些如此没有。
如：can-could,may-might,shall-should,will-would,have to -had to,dare-dared;但must,ought to ,had better如此只有一种形式。
1. can和could①表示“现在的能力〞用can，“过去的能力〞用could。
We can use the computer now,but we couldn’t 10 years ago.②表示“许可〞或征询对方的许可，可用can,could〔语气委婉，不表示过去〕，用may 〔较正式〕，回答时不用could.—Can/Could/May I go now?—Yes,you can/may.③表示“可能性〞时，can多用于否认句和疑问句，表“不可能，可能吗〞之意。
肯定句可用could,may,might〔语气更不地道〕The story could/may /might/be true.He can’t be at home now.④can和be able to 都可以表示能力，但can/could表一般性的程度上的能力。
be able to如此表示具体的成功的做成某事。
A strong wind added to his difficulty,but he was able to swim across the channel.2.may 和might①表示“许可〞或征询对方许可。
否认回答时，根据语气的强弱依次为may not,had better not 和mustn’t.You may use the phone.〔现在〕He said I might use the phone.〔过去〕—May I go out with him?—Yes,you may.—No,you may not/had better not/mustn’t.②表示可能性，有“或许，可能〞的意思。
高二英语下册 Unit 13 Water Planet 教案 人教版大纲
Unit 13 The Water PlanetThe topic of this unit is “water”, including the properties of water, estuaries, the ocean and the importance of using and protecting our water. In the warming up, there are four experiments related to water for the Ss to tell the results and explain the reasons. The listening part is about the story of an adventurous sea journey—“The rime of the old mariner”, written by the English poet Coleridge. In the speaking part, Ss will see some pictures showing some examples of how we use water in different ways. Ss will talk with their partners about the importance of using and protecting our water. The reading passage is “the properties of water”, introducing the chemical structure, salinity, density, heat capacity and ocean motion. The language study is designed to get the Ss to do some vocabulay exercises and review the modal verbs. In the Integrating Skills, the Ss is given a passage about nature’s nursery: estuaries to read and write a paragraph to answer the questions, using the knowledge learned in this unit.To get more output from the Ss, we must give them more input. Reading is a kind of input. The main topic of the unit is “water”, so the Ss must know the basic knowledge of water at first so that they can use what they have learned about the matter to explain some phenomena and to have discussions with their partners. So I put the reading as the first lesson of theUnit and have the warming up activity as one of the reading activities to check the Ss’ understanding of the reading passage. The second period is a kind of output, that is to have discussions about the using and protecting of water; while the third period is about the tale or story about water and the fourth period the protection of oceans.Period 1 ReadingGoals1. Provide the Ss with the opportunity to know about the water planet and the properties of water.2. Help the Ss explain some phenomena using the knowledge they learned from the reading material.3.

Why?Experiment 3: put a piece of chalk in water for 24 hours. What happens? Why?Then show them two pictures of people who are floating on the surface of Dead Sea. Ask them to explain how they can do this.Purpose: To help the Ss use what they have learned from the reading passage to explain some phenomena.Step 5. ConcludingAsk:Why must we learn about the properties of water?Purpose: To draw a conclusion of the reading passage and get the Ss to know the importance of using and protecting water and raise their awareness of water protection.Period 2 SpeakingGoals: 1.

语法精讲情态动词情态动词是动词的一种，顾名思义，表示说话人的情感或态度，认为“可能/应当/必要”，或表达“怀疑/命令/许可”等。
情态动词没有人称和数的变化。
情态动词本身词义不全，不能单独作谓语，必须和动词原形连用，共同构成谓语动词。
有些情态动词有过去式，有些则没有。
如：can-could,may-might,shall-should,will-would,have to -had to,dare-dared;但must,ought to ,had better则只有一种形式。
1. can和could①表示“现在的能力”用can，“过去的能力”用could。
We can use the computer now,but we couldn’t 10 years ago.②表示“许可”或征询对方的许可，可用can,could（语气委婉，不表示过去），用may （较正式），回答时不用could.—Can/Co uld/May I go now?—Yes,you can/may.③表示“可能性”时，can多用于否定句和疑问句，表“不可能，可能吗”之意。
肯定句可用could,may,might（语气更不地道）The story could/may /might/be true.He can’t be at home now.④can和be able to 都可以表示能力，但can/could表一般性的程度上的能力。
be able to则表示具体的成功的做成某事。
A strong wind added to his difficulty,but he was able to swim across the channel.2.may 和might①表示“许可”或征询对方许可。
否定回答时，根据语气的强弱依次为may not,had better not 和mustn’t.You may use the phone.（现在）He said I might use the phone.（过去）—May I go out with him?—Yes,you may.—No,you may not/had better not/mustn’t.②表示可能性，有“或许，可能”的意思。
用might语气更加没有把握，指现在时间。
John should arrive here before eight,but he may not,He is often late.I’m not sure whether I’m coming to the party.I might go to the night school instead.3.must 和 have to①must表示“必须，应该”，是说话人的主观看法。
have to 表示“必须”“不得不”，表示的是客观需要。
must只有一种形式，have to 有has to,had to,will have to 等多种形式。
I don’t like the flat.I must buy another one.The flat is too small for five people.I have to buy a large one.②“mustn’t”表示“不应该”“不许可”“禁止”“不准”。
因此在回答must问句时，否定式常用needn’t或don’t have to。
You mustn’t climb that electrical pole.—Must I finish the job before nine tonight?—Yes,you must.—No,you needn’t./don’t have to.③must还可以表示猜测，意为“一定”“肯定”，只用于肯定句中，否定句用can’t.He must be at home.The lights are on.He can’t be /come from England.He doesn’t speak English.4.shall,should和ought to①征询对方的意见或主动提出干某事。
Shall I get some chalk,Mr.Black?Shall he come in now ?②shall用于第二、三人称陈述句中时，表示说话人命令/警告/强制/允诺等语气。
You shall do as I say.Tell him that he shall have the book tomorrow.③should表“劝告”“建议”，译作“应当”，常表示主观看法。
还可表示必要/惊奇/遗憾等语气，译为“应该，竟然会”。
ought to 语气比should稍重些，可表示“义务”“要求”“劝告”，译作“应当”，常表示客观情况，否定形式为ought not to,疑问式为ought I /he to…？You should keep your promise.Can you imagine that a well-behaved gentle-man should be so rude to a lady?If he started off on time,he ought to be here now.5.will和would①will表“意愿”，可用于各种人称。
would表过去时间的“意愿”。
I will keep the secret for you.They promised that they would help us.②will在疑问句中用于第二人称时，表示询问对方意愿或向对方提出请求，这时would 语气比will婉转，指现在时间。
We’re going on a holiday,will you?Will you please pass me the book?Would you like to join us?6.had better和would ratherhad better表“义务”或“建议”，常译作“最好……”“还是……好”。
语气比should,ought to 委婉，可用于第一、二、三人称。
would rather表示“宁愿”“更喜欢”。
We/You/He had better write it down.You’d better not ask her about it.I would rather go there tomorrow.Yuan Longping would rather not be well-known.7.need和dareneed 和dare作情态动词时，只用于疑问句和否定句。
need意为“需要，必需”，dare 意为“敢，胆敢”。
You needn’t make so many dishes.Need we do it now？—Yes,we must.—No,we needn’t.She dare not touch the wire.How dare you say I am unfair?8.“情态动词+have done”是历年高考的热点，不同的情态动词意思稍有差别。
must have done表示对过去情况的推测和估计，意为“想必肯定已经做了某事”。
may/might have done可能，大概（已经）做了某事，可能性比must have done小。
can/could have done 用于疑问句中“可能已经……了吗”。
could have done 表本来能做却没有做的责备语气。
can’t/couldn’t have done表示对过去情况的否定性推测，“不可能已经做了某事”。
should/ought to have done 表示过去该做某事而没有做,表后悔、遗憾等语气。
shouldn’t/oughtn’t to have done表示不该做而做了某事，也表示后悔、遗憾等语气。
needn’t have done表示原本不必做却已经做了某事。
would rather have done本为想做却没做成某事。
(1)The ground it wet.It must have rained last night,didn’t it?(2)Tom may/might have gone to Shanghai,but I’m still not sure about it.(3)The house was broken into.Who could have done that？(4)I could have stayed with Susie,but I didn’t get in touch with her.(5)I didn’t see her at the party.She can’t have been there.(6)I really regretted wasting the hours when I should have studied,but it was too late.(7)You shouldn’t have come late again.(8)You needn’t have come so early.(9)I would rather have com e to help you,but an unexpected guest came.考题再现【考例1】(2006全国高考Ⅰ,24) There’s no light on—they______be at home.A.can’tB.mustn’tC.needn’tD.shouldn’t解析:“can’t+动词原形”表示对现在情况的猜测或判断，意为“不可能”。
根据所提供的情景“There’s no light on”可判断出他们不可能在家。
mustn’t后接动词原形，表示“禁止，不准”，不用于表示猜测、推测或判断。
needn’t意为“没必要”，表示没有必要做某事。
shouldn’t意为“不应该”，表示不应该做某事。
答案:A【考例2】(2006全国高考Ⅱ，10) We hope that as many people as possible ______join us for the picnic tomorrow.A.needB.mustC.shouldD.can解析:句意是“我们希望尽可能多的人能参加我们明天的野炊。
”表示可能性用can。
答案:D【考例3】(2006上海高考，26) Black holes ______not be seen directly,so determining the number of them is a tough task.A.canB.shouldC.mustD.need解析:本题句意为“黑洞直接用肉眼不能看见，因此确定它们的数量是一项艰巨的任务”。
