Unit 4 Astronomy: the science of thestarsPeriod 1 Warming up and new wordsTeaching Goals:1. To arouse Ss’ interest in the knowledge of astronomy and science。
.2. To develop Ss’ ability in listening and speaking.Teaching Procedures:Step 1. Leading- inGive Ss a few minutes to say something about science by asking the following questions.（1.）Who is the first man in space，do you know？（2.）Which spaceship did Yang Liwei take to space？（3.）Do you want to go to space if you are given a chance?Step 2. Warming UpPurpose: To introduce the topic of this unit to Ss in the form of asking questions and discussion.Ask some Ss the questions first and then get Ss to discuss with each other. If time permits, have one or two groups present their answers to the whole class. (1) How many subjects are we studying now?（2）Do you have some scientific studying methods to learn them well?(3) As you see, a large number of students want to become scientists in thefuture. But what kind of qualities and skills do we need to be realscientists?Step 3. Talking (Workbook)1. Divide Ss into six groups, and ask them to talk about the request of Talking on P62 and answer the following questions. Different students will give different answers. Make notes of some valuable information and make a conclusion at last. (1) What necessary instructions should new space travelers make?(2) Can you make a list of them?2. Show Ss some beautiful pictures of the university and say, “Now look at the pictures. How beautiful the Universe is! It is also full of mysteries. Have you ever dreamed of flying to the space like Yang Liwei to unlock the mysteries of the universe? If you could, what things should you pay attention to?”3. Encourage Ss to give as much information as possible. After the discussion, write down some key words and important expressions on the blackboard to help Ss to have the sense of traveling in space .Conclusion:Before making a trip into space, we’d better make full preparations, such as : collecting as much information about the space as possible; checking whether you have got the proper spacesuits or not; making sure of all the safety rules; not leaving the spaceship alone unless the space guide tells you to; paying attention to recording some important time during the space traveling and so on.Step 3. Listening (Workbook)Purpose: To develop Ss’ listening ability.To gain some experience of traveling in space1. Get Ss to look through the exercises before giving them the listening material. At the same time remind them of the new and key words: astronaut, experience, instruments, pilot, air force, rocket.2. Ask Ss to look through the questions of the first part and listen to the tape carefully. Play the tape twice. For the first time, just ask Ss to listen for the gist. For the second time, ask Ss to prepare to do the exercises. If time permits, play again in order to give the class a chance to check or complete their exercises.。

Ⅱ.单句改错1.All the visitors were told to watch out those dangerous animals while visiting the zoo.out后加for2.This river is three times long than that one，flowing through 11 provinces.long→longer3.—What do you think of French？—In my opinion，French is as difficult subject as English.difficult后加a4.We should try our best to cheer on those people after the disaster.on→up5.After the long journey，the three of us went back home，exhausting. exhausting →exhaustedⅢ.课文语法填空Last month，Li Yanping and I made a trip to the moon，1.in a spaceship.Li told me that the gravity force would change three times.First，2.when we escaped the pull of the earth’s gravity，we 3.were__pushed(push)back into our seats.Closer to the moon，there was 4.less(little) gravity.I 5.cheered(cheer) up immediately and floated 6.weightlessly(weight)around in our spaceship cabin.On the moon，my weight was less than on the earth.Walking 7.did(do) need a bit of practice now that gravity had changed.After a while I got the hang 8.of it and we began to enjoy 9.ourselves(our).But returning to the earth was very 10.frightening(frighten).We watched，amazed as fire broke out on the outside of the spaceship.Ⅳ.阅读理解ARed dwarf stars (红矮星) can range in size from a hundred times smaller than the sun，to only a couple of times smaller.Because of their small size these stars burn their fuel very slowly，which allows them to live a very long time.Some red dwarf stars will live trillions of years before they run out of fuel.Then why are red dwarf stars red？Because red dwarf stars only burn a little bit of fuel at a time.They are not very hot pared to other stars.Think of a fire.The coolest part of the fire at the top of the flame glows red，the hotter part in the middle glows yellow，and the hottest part near the fuel glows blue.Stars work thesame way.Their temperatures determine what color they will be.Thus we can determine how hot a star is just by looking at its color.Like the Sun，these medium－sized stars are yellow because they have a medium temperature.Their higher temperature causes them to burn their fuel faster.This means they will not live as long，only about 10 billion years or so.Near the end of their lives，these medium－sized stars swell up being very large.When this happens to the Sun it will grow to engulf(吞没) even the Earth.Finally they shrink again，leaving behind most of their gas.This gas forms a beautiful cloud around the star called a planetary nebula(行星状星云).When will the Sun expand into a giant，and then shrink leaving behind a planetary nebula？Don’t worry.The Sun is only about 5 billion years old.It still has another 5 billion years before it will expand，and then turn into a planetary nebula.The Sun is so hot that when it dies，it will take a long time to cool off.The sun will die in about 5 billion years，but it will still glow for many billions of years after that.As it cools，it will be what is called a white dwarf star.Finally，after billions maybe even trillions of years，it will stop glowing，at that point it will be what we call a black dwarf star.There are still no black dwarf stars in the Universe.【语篇解读】这是一篇说明文。

When the fragments(碎片)landed in the southern part of the grand planet, the explosions were watched by scientists here on earth. But what if our own planet was hit by a comet?The year is 2094. It had been announced that a comet is heading towards the earth. Most of it will miss our planet, but two fragments will probably hit the southernpart of the earth. The news has caused panic.On 17 July, a fragment four kilometers wide enters the Earth's atmosphere with a huge explosion. About half of the fragment is destroyed. But the major part survives and hits the South Atlantic at 200 times the spend of sound. The sea boils and an enormous wave is created and spreads. The wall of water rushes towards southern Africa at 800 kilometres an hour. Cities on the African coast are totally destroyed and million of people are drowned. The wave moves into the Indian Ocean and heads towards Asia.Millions of people are already dead in the southern part of the earth, but the north won't escape for long. Tons of broken pieces are thrown into the atmosphere by the explosion. As the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. Wars break out as countries fight for food. A year later civilization has collapsed. No more than 10 million people have survived.Could it really happen? It has already happened more than once in the history of the earth. The dinosaur were on the Earth for over 160 million years. Then 65 million years ago they suddenly disappeared. Many scientists believe that the Earth was hit by a space fragment. The dinosaurs couldn't survive in the cold climate that followed and they became extinct. Will we meet the same end?36．Which of the following is NOT true according to the author's description of the disaster in 2094?A．The whole world becomes extremely cold.B．All the coastal cities in Africa are destroyed.C．The whole mankind becomes extinct.D．The visit of the comet results in wars.答案：C 辨别正误题.据第三自然段的描述可知,A、B、D均符合本文所假想的事实,只有C不符.文中“No more than 10 million people have survived”一句意为“只有一千万人幸存下来”,而C项说全人类都灭绝了.显然与文章不符.题干要求找出不对的选项.37．Why does the author mention dinosaurs at the end of the passage?A．Because they could only live in the warm climate.B．Because they once dominated the earth.C．Because their extinction indicates future disasters.D．Because dinosaurs and humans never live in the same age.答案：C 推理判断题.第三段中,作者描述假想的人类灾难……最后一段提到生活在地球上的恐龙在65 million years ago突然消失(即灭绝),许多科学家相信地球曾受到过外空星体碎片的袭击,故而导致恐龙绝种.由此暗示人类未来的灾难.38．In writing the passage, the author intends to________.A．give an accurate description of the possible disaster in the futureB．prove that humans will sooner or later be destroyedC．tell the historical development of the earthD．warn of a possible disaster in the future答案：D 观点态度题.本题要求考生推测作者意图.作者通过一段幻想的灾难和一段地球历史上出现过的恐龙绝迹的事实以及科学家们分析恐龙绝迹的原因,来警示人类未来可能发生的灾难.39．It can be concluded that the passage is most probably part of a(n)________．A．horror storyB．news reportC．research paperD．article of popular science答案：D 推理判断题.据全文大意,又据文章的性质,可判定D为最佳选项.A、B、C均不太妥当.B(2014·山西省大同高一下学期期中) Satellites are an important part of our ordinary lives. For example, the information for weather forecasts is sent by satellite. Some satellites have cameras which take photographs of the Earth to show how clouds are moving. Satellites are also used to connect our international phone calls.Computer connections of the World Wide Web and Internet also use satellites. Many of our TV programs come to us through satellites. Airplane pilots also sometimes use a satellite to help them find their exact location.We use satellites to send television pictures from one part of the world to another. They are usually 35, 880 kilometers above the equator. Sometimes we can see a satellite in the sky and it seems to stay in the same place. This is because it is moving around the world at 11,000 kilometers an hour—exactly the same speed that the earth rotates. A satellite must orbit the Earth with its antennae (天线) facing the earth. Sometimes, it moves away from its orbit. So there are little rockets on it which are used to put the satellite back in the right position. This usually happens about every five or six days.Space is not empty! Every week, more and more satellites are sent into space to orbit the Earth. A satellite usually works for about 10－12 years. Satellites which are broken are sometimes repaired by astronauts or sometimes brought back to Earth to be repaired. Often, very old or broken satellites are left in space to orbit the Earth for a very long time. This is very serious because some satellites use nuclear power and they can crash into each other.40．Which of the following is NOT done by satellites according to the passage?A．Sending information for weather forecast.B．Taking photographs of the Earth.C．Sending TV pictures.D．Providing food for airplane pilots.答案：D 从第一段可知,A、B项的内容都是卫星的功能,从第三段可知,卫星还可以发送电视画面,而D项内容文中并未提及.41．What's the speed the earth rotates at?A．35,880 kilometers per hour.B．335,880 kilometers per hour.C．11,000 kilometers per hour.D．110,000 kilometers per hour.答案：C 从第三段的This is because it is moving around the world at 11,000 kilometers an hour—exactly the same speed that the earth rotates.可知C项为正确答案.42．What does the underlined w ord “This” in the 3rd paragraph refer to?A．A satellite.B．A little rocket.C．A satellite seems to stay in the same place in the sky.D．The satellite puts the rockets in the right position.答案：C 上一句话的意思是：有时候我们看到天空中的卫星好像呆在同一个地方,这是因为……,故本题答案为C.43．Which is true of satellites?A．A satellite usually works for about 10－12 years.B．Every time a satellite gets broken, it is brought back to the Earth to be repaired.C．A broken satellite is never left in space.D．They often crash into each other.答案：A 从最后一段的第三句话可知A项正确.CBrian arrived at the San Francisco airport two hoursbefore the flight to Paris. He was wearing threeshirts, a jacket,two pairs of socks,a pair of shorts, and twopairs of jeans. He was carrying one small backpack,which was veryfull, but he didn't have any other luggage. Brian needed to meet a man named Tony before he checked in for his flight. He found Tony near the Air France counter. Tony gave him a roundtrip ticket and a small package.“Give this package to Jean Paul at the airport in Paris. He will have a sign with your name on it. I think you can find him easily,” Tony said,“You don't have any luggage, right？”“Only this backpack,” Brian answered,“You said I could bring one carryon bag.”“That's right. One carryon bag is fine. Have a good trip.”“Thanks.”Is Brian a criminal? Not at all. He is an aircourier. And he paid only $ 110 for the roundtrip ticket to Paris. Aircouriers get cheap airline tickets because they take important packages and papers to foreign countries. Businesses sometimes need to get packages and papers to people in foreign countries by the next day. Often,the only way they can do this is to use an aircourier company. It is not cheap for a business to send a package with an aircourier,but it is quick.Every year about 80,000 people worldwide travel as aircouriers. The number of tickets for courier travel is growing by about 10 percent a year. However, aircourier travel isn't for everyone. But if you have very little money,can be flexible about your travel plans,and don't mind wearing the same clothes for a week,it can be a great way to take a vacation!文章大意：文章主要讲述了利用航空快递的利与弊.44．Why was Brian wearing so many clothes for his travel?A．Because they were the uniforms for aircouriers.B．Because that made him easier to be recognized.C．Because he would be charged for taking much luggage with him.D．Because he was required not to have much luggage with him.答案：D 细节理解题.由第三段“Only this backpack,” Brian answered, “You saidI could bring one carryon bag.”可知,Brian只被允许带一个背包.45．Who was Tony?A．He might be an aircourier company clerk.B．He might be a guard at the airport.C．He might be Brian's friend.D．He might be a customs official.答案：A 细节理解题.根据第一段中“Tony gave him a roundtrip ticket and a small package.托尼给了他(Brian)一张往返的机票及一个小包裹”,以及结合下文可知,Tony可能是一位航空快递公司的业务员.46．Businesses choose the aircourier service because ________.A．it costs less B．it is flexibleC．it grows fast D．it saves time答案：D 细节理解题.从倒数第二段最后一句“It is not cheap f or a business to send a package with an aircourier,but it is quick.用航空快递投递包裹不便宜但是它迅速.”可知选D.47．Aircourier travel is a good choice for those who ______.A．have much moneyB．hate wearing the same clothesC．have much personal luggageD．are flexible about their travel plans答案：D 细节理解题.根据最后一段最后两句话可知“航空快递旅行并不是适合每一个人.它主要面向那些钱少,旅行计划比较灵活的游客”,故选D.DThe journey to the moon has been the first step towards future exploration in space. The distance between the Moon and Earth is very short indeed when compared with the distances between Earth and the other planets. Mars, the nearest planet to Earth is millions of miles away! Traveling to the planets will be man's next aim. Such travels will be more challenging than the trip to the moon and certainly more adventurous.Recently, two American spaceships, Vikings 1 and 2, landed on Mars trying to discover whether that planet has any life on it. So far the signs of life on Mars has neither confirmed(确认)nor ruled out. Russians have discovered that the surface of Venus(金星)is so hot that it is almost certain that there is no life there. Also the atmosphere of Venus is extremely dense(稠)and the pressure is nearly a hundredtimes greater than that of the Earth's atmosphere.Scientists believe man may find planets which have the same conditions as those we have on earth, but man should realize Earth will be his only home for a long time and begin to love and care for it.48．According to the passage, traveling to the planets will be________.A．much easier and even more interestingB．far more exciting and dangerousC．man's final aimD．man's first step答案：B 细节理解题.由文章第一段告诉我们人类向其他行星探索的行动将比去月球探索更加具有挑战性和冒险性.49．From the passage, we can guess________.A．there is life on MarsB．there is no life on MarsC．The atmosphere of Mars is not so dense as that of VenusD．scientists will have little hope to find the answers答案：C 推理判断题.由文中第二段第二句告诉我们,火星上是否有生命还不能确认,所以A、B排除.根据文章最后一段第一句可知：科学家相信人类能找到像我们地球上生存条件一样的行星.所以可以排除D.50．Scientists think we should take care of our earth because________.A．no other planets are to take the place of the earthB．everything needed is provided by the earthC．the only home of man will be the earth for a long timeD．the dream to find another home for man will come true答案：C 细节理解题.最后一段讲明人类必须保护地球.根本原因在于人类在近期内无法找到能够和地球的生存常规交叉相提并论的星球,所以地球在很长时间内依然是人类赖以生存的家园.E(2013·天津) Last night's meteor(流星) shower left many people in the community dissatisfied and demanding answers. According to Gabe Rothschild, Emerald Valley's mayor, people gathered in the suburbs of the city, carrying heavy telescopes, expecting to watch the brightly burning meteors passing through the sky. What they found instead was a sky so brightened by the city's lights that it darkened the light of the meteorspassing overhead.“My family was so frustrated,” admitted town resident Duane Cosby, “We wanted to make this an unforgettable family outing, but it turned out to be a huge disappointment.”Astronomers—scientists who study stars and planets—have been complaining about this problem for decades. They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past. They call on people and the government to take measures to fight against it.There is yet a population besides professional and amateur star observers that suffers even more from light pollution. This population consists of birds, bats, frogs, snakes, etc. For example, outdoor lighting severely affects migrating(迁徙的)birds. According to the International DarkSky Association. “100 million birds a year throughout North America die in crashes with lighted buildings and towers.”Countless more animals casualties(伤亡)result from the use of artificial lighting. Clearly, people enjoy the benefits of lighting their evenings, but some scientists think it can be harmful for humans, too. They worry that exposure to light while sleeping can increase a person's chances of getting cancer.Emerald Valley is only one community that is becoming aware of the negative effects of light pollution. For years, Flagstaff, Arizona, has enforced lighting regulations in its city in order to assist astronomers at the Lowell Observatory. Similar efforts have been made worldwide, and a movement is underway to remind us to turn off lights when we are not using them, so that other creatures can share the night.文章大意：本文是一篇议论文,作者通过一场不令人满意的流星雨引出话题,阐述了光污染对于人类及动物所造成的危害,号召人们不需要的时候,把灯关掉.51．It happened last night that ________.A．the city's lights affected the meteor watchingB．the meteors flew past before being noticedC．the city light show attracted many peopleD．the meteor watching ended up a social outing答案：A 细节理解题.由第一段最后一句话：他们发现的是被城市灯光照得如此明亮的天空使得划过我们头顶的流星暗淡无光,所以可以知道城市灯光影响了流星雨的观看.故选A项.52．What do the astronomers complain about?A．Meteor showers occur less often than before.B．Their observation equipment is in poor repair.C．Light pollution has remained unsolved for years.D．Their eyesight is failing due to artificial lighting.答案：C 细节理解题.由第三段一、二句话,可知天文学家们几十年来以直报怨这个问题,说明光污染的问题多年没有解决.故选C项.53．What the author concerned about according to Paragraph 4?A．Birds may take other migration paths.B．Animal's living habits may change suddenly.C．Varieties of animals will become sharply reduced.D．Animals' survival is threatened by outdoor lighting.答案：D 细节理解题.第四段主要讲了室外光对于动物的影响,所以作者担心动物的生存受到室外光的威胁.故选D项.54．Lighting regulations in Flagstaff, Arizona are put into effect to ________.A．lessen the chance of getting cancerB．create an ideal observation conditionC．ensure citizens a good sleep at nightD．enable all creatures to live in harmony答案：B 细节理解题.由最后一段第二句话可知这个城市加强灯光规定是为了帮助观测台的天文学家们,也就是创造一个理想的观测条件.故选B项.55．What message does the author most want to give us?A．Saving wildlife is saving ourselves.B．Great efforts should be made to save energy.C．Human activities should be environmentally friendly.D．New equipment should be introduced for space study.答案：C 目的意图题.全文是关于光污染所造成的危害,也就是让人们知道人的活动应该注意环境保护.Ⅳ.书面表达(满分25分)(2014·湖南) Directions: Write an English composition according to the instructions given below.学校正在组织科技创新大赛,你想为日常生活中某件物品(如钢笔、书包、鞋子……)设计添加新功能来参赛.请以“My Magic ________”为题写一篇英语短文,介绍你的创意.内容：1．说明设计理由；2．介绍新功能.注意：1．词数不少于120个；2．不能使用真实姓名和学校名称.________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ 参考范文：My magic neutral water penThe neutral water pen is widely used in the process of study but we often have trouble using them because of its limited ink and other inconvenience.To deal with these problems, consequently, I have worked heart and soul to create my own magic neutral water pen.The most shining function of this newly designed pen is that it will contain special ink powder which makes it have endless ink.
