Some people think that water ices and milk ices may have been made by the Chinese between three thousand and four thousand years ago. In time, the dish reached India. The Indians, in turn, may have passed on the secret to the Arabs and Persians. The Persians called their dish Sharbat, from which our word sherbet（冰冻果子露）comes.Marco Polo, an Italian who traveled widely in the thirteenth century, noted that he found the Chinese had long been making ices out of fruit juices and milk. From the fourteenth century on, ices became popular, first in Venice and then throughout Italy.In 1533, when Catherine de Medicis left Italy to marry the future King Henry Ⅱof France, she took her cooks with her. They made desserts the French had never tasted before. Among them was "ice cream". For each day of the wedding festivities（庆祝活动，庆典）Catherine's cooks prepared a different flavor of her favorite dessert-"ice cream."At first ice cream was a luxury in France. Only rich people had money to buy it. Then, in 1660, a young man from Sicily, Francisco Procopio, arrived in Paris. He opened a shop that sold ice cream at prices people could afford. Procopio's"ice-cream parlor " became so popular that other shops were opened.About 1640, King Charles I introduced ice cream to England. He had heard it was popular in Italy and France. He served ice cream for dessert at a banquet. The surprise dish was a great success. The King ordered his cook to keep the recipe for ice cream a secret. Charles felt that only royalty should serve the dessert. But the secret soon leaked out. Ice cream quickly became popular in England too.21、This passage is mainly about the history of ice cream.A：TB：F22、Marco Polo's remark shows that he traveled in India.A：TB：F23、Ice cream was unknown in France until 1640.A：TB：F24、Ice cream was introduced to England by King Charles I.A：TB：F25、Development of ice cream in France and other countries is discussed in the passage.A：TB：F（二）The French Revolution broke out in 1789. At the time France was in a crisis. The government was badly run and people's lives were miserable. King Louis XIV tried to control the national parliament and raise more taxes. But his effort failed. He ordered his troops to Versailles. The people thought that Louis intended to put down the Revolution by force. On July 14, 1789, they stormed and took the Bastille, where political prisoners were kept. Ever since that day, July 14 has been the French National Day. Louis tried to flee the country in 1792, to get support from Austria and Prussia. However, he was caught and put in prison. In September 1792, the monarchy was abolished. In the same year, Louis was executed. A few months later his wife, Marie, also had her head cut off. The Revolution of France had frightened the other kings of Europe. Armies from Austria and Prussia began to march against France. The French raised republican armies to defend the nation. The Revolution went through a period of terror. Thousands of people lost their lives. In the end, power passed to Napoleon Bonaparte.26、What's this passage about?A：France.B：King Louis.C：The French Revolution.27、Which did not happen in 1789?A：The French Revolution broke out.B：The national economy was developing rapidly.C：The government wasn't well run.D：King Louis XIV was in power.28、Where were the political prisoners kept?A：In Versailles.B：In Austria.C：In Prussia.D：In Bastille.29、What does the underlined word "abolished" mean?A：Put off.B：EstablishedC：UnitedD：Ended30、What was NOT the effect of the Revolution?A：July 14 has become the French National Day.B：It brought some impact on the other European kings.C：Louis's wife, Marie was killed.D：The king tried to control the national parliament.三、完型填空The last patient left his office.

Slowly, as she worked on the long list, she began tofeel uncertain. She began to question some of her decisions. Had she used the best technique in that case? Maybe, in this case, she should have run one more test before operating? On the other hand, maybe she should have … Would the doctors on the selection committee understand that, as the only trained surgeon in the area, she usually could not get advice from others and therefore, had to rely completely on her own judgment? For the first time, Dr. Ginoux felt lonely and isolated.The longer Dr. Ginoux worked on the application forms, the more depressed she became.

Crude oil, or petroleum – a dark, thick ooze from the earth – had been known for hundreds of years. But little use had ever been madeof it. In the 1850’s Samuel M. Kier, a manufactur er in the western Pennsylvania, began collecting the oil from local seepages andrefining it into kerosene, Refining, like smelting, is a process of removing impurities from a raw material.Kerosene was used to light lamps. It was a cheap substitute for whale oil, which was becoming harder to get. Soon there was a large demand for kerosene. People began to search for new supplies of petroleum.The first oil well was drilled by E. L. Drake, a retired railroad conductor. In 1859 he began drilling in Titusville, Pennsylvania. The whole venture seemed so impractical and foolish that onlookers called it “Drake’s Folly”. But when he had drilled down about 70 feet (21 meters), Drake struck oil. His well began to yield 20 barrels ofcrude oil a day.News of Drake’s success brought oil prospectors to the scene. By the early 1860’s these wildcatters were drilling for “black gold” all over western Pennsylvania. The boom rivaled the California gold rush of 1848 in its excitement and Wild West atmosphere. And it brought far more wealth to the prospectors than any gold rush.Crude oil could be refined into many products. For some years kerosene continued to be the principal one. It was sold in grocerystores and door-to-door. In the 1880’s refiners learned how to make other petroleum products such as waxes and lubricating oils. Petroleum was not then used to make gasoline or heating oil.(1).Which of the following is the best title for the passage?A. Oil Refining: A Historical PerspectiveB. The California Gold Rush: Get Rich QuicklyC. Private Property: Trespassers Will Be ProsecutedD. Kerosene Lamps: Trespassers Will Be Prosecuted(2).It can be inferred from the passage that Kerosene was preferable to whale oil because whale oil was too ________.A. expensiveB. thickC. hotD.polluted(3).Why does the author mention the California gold rush?A. to explain the need for an increased supply of goldB. toindicate the extent of United States mineral wealth C. to describethe mood when oil was first discovered D. to argue that gold was more valuable than oil(4).The word “one” in the second sentence of the last paragraph could best be replaced by which of the following words?A. oilB. doorC. storeD. product(5).The author mentions all of the following as possible products of crude oil EXCEPTA. waxB. gasolineC. KeroseneD. plastic答案：一、单项选择题（80分，共 40 题，每小题 2 分）1. C2. D3. D4. C5. A6. A7. A8. D9. B 10. C 11. C 12. A 13. A14. A 15. C 16. B 17. B 18. D 19. B 20. C 21. C 22. C 23. A 24. A 25.C 26. A 27.D 28. B 29.

Each one is carrying a small basket with a single egg inside. Soon more students join them-each one of them is also carrying a basket with an egg. The eggs in a basket are part of a new school program that helps young people understand that having a baby is a great duty.At the beginning of the program, the teacher puts the students in pairs-one girl and one boy. Each pair gets an egg, which they must take care of for two weeks. For those fourteen days, the students have to take care of the eggs as though they were real babies. Students whose eggs get broken have to start the two weeks all over again with a new egg.One person in each pair must have the egg with him or her at all times-twenty-four hours a day. At no time can they let the egg be out of sight. "If a teacher catches you without your egg," said one student, "she makes you go get it. They are really strict." The teachers also make the students spend half an hour each day sitting with the egg and just watching it. That can get pretty boring. But it's also something that parents spend a lot of time doing.Children say that the program has helped them understand the duties involved inhaving a child. "It was really hard," said one student, "You had to think all the time about the egg."(5)、From the last paragraph, we can infer that ______.Aa program is the only way to educate childrenBone has to think about a program all the timeConly one child grasps the purpose of the programDthe program is of help to children's understanding of parents正确答案是：D23、Mr. Liu, _______ at university in Changchun, works at Changhou Company now.

Our reactions help to determine whether our child will repeat his behavior or whether he will do something different. This statement is a very important part of a principle of behavioral psychology.The principle states that a behavior is influenced or affected by how the environment ---- people, places and things ---- immediately responds to the behavior. Perhaps without realizing it, you have used this principle many times.On the occasion when you told your child what a good boy he was after he cleaned up his room, you used the principle. When you sent your child to his room for fighting with his brother, you used the principle. When I gave Kim a cookie after she started to cry, I used the principle. In each of these examples, a particular behavior occurred first ----cleaning up a room, fighting, and crying.In addition, there was a reaction to each behavior ---- the child was praised, sent to his room, or given a cookie. By these actions, we have influenced the previous behaviors and have helped to determine whether those behaviors will occur again in the future.(2) On what kind of principle is the lecture based?AA principle in chemistry.BA principle in behavioral psychology.CA principle in physics.DA principle in geology.正确答案是：B36、— _______ —Yes, I’ll be happy to cash it for you.ADo you need any cash?BAre you happy with the cash?CAre you happy to cash it for me?DMay I cash a traveler’s check here?正确答案是：D37、—Bring me the bill, please.— _______AYou are welcome.BPlease wait for a moment, sir.CI'll hurry up.DBe quick正确答案是：B38、We go to the cinema ______ a week.AoftenBonceCseldomDusually正确答案是：B39、If you _______ me, I shall be very grateful to you.Amust helpBwill helpCmay helpDneed help正确答案是：B40、Unemployment is not the _______— the real problem is the decline in public morality.

People play different games in winter and summer.Games and sports often grow out of people's work and everyday activities. The Arabs use horses or camels in much of their everyday life; they use them in their sports, too.Some sports are so interesting that people everywhere go in for them. Football, for example, has spread around the world. Swimming is popular in all countries near the sea or in those with many rivers.Some sports or games go back to thousands of years ago, like running or jumping. Chinese boxing, for example, has a very long history. But basketball and volleyball are rather new. Neither one is a hundred years old yet. People are inventing new sports or games all the time.People from different countries may not be able to understand each other, but aftera game they often become good friends. Sports help to train a person's character. One learns to fight hard but fight fair, to win without pride and to lose with grace.(4)、From this passage we can see that according to the author sports and games are significant to our life in many respects.A错误B正确正确答案是：B2、Albert Einstein had a great effect on science and history, greater than what only a few other men have achieved. An American university president once commented that Einstein had created a new outlook, a new view of the universe. It may be some time before the average mind understands fully the identity of time and space and so on-but even ordinary men understand now that the universe is something larger than ever thought before.By 1914 the young Einstein had gained world fame. He accepted the offer to become a professor at the Prussian Academy of Science in Berlin. He had few duties, little teaching and unlimited opportunities for study, but soon his peace and quiet were broken by the First World War.Einstein hated violence. The misery of war affected him deeply, and he sat unhappily in his office doing little. He lost interest in his research. Only when peace came in 1918 was he able to get back to work.In the years following World War I honors were increasingly heaped on him. He became the head of the Kaiser Whihem Institute of Theoretical Physics. In 1921 he won the Noble Prize, and he was honored in Germany until the rise of Nazism when he was driven from Germany because he was a Jew.(1)、The main idea of Paragraph 1 is the change in human thought produced by Einstein. A错误B正确正确答案是：B3、In 1920, barely out of his teens, Alfred Hitchcock went to work for an American film company which had opened a studio in Islington, London.

Within two years, he was writing scripts（剧本）and working as an assistant director.For the rest of the 1920s, Hitchcock worked on one film after another in Britain and Germany.

A scene needed rewriting, Hitchcock rewrote it. Someone needed to be in charge of money when the film crew was on location, Hitchcock looked after the money.At the same time, this being the era of silent movies, Hitchcock was learning the language of cinema: telling a story－not through dialogue, but through visual images（视觉影象）.

Then everything changed. During the Fourth of July weekend, residents woke up one morning to find that the lake had disappeared.Some people didn't believe what they were seeing. They looked again, but to their amazement they found they had been right the first time. The lake was simply no longer there. In its place was a big muddy hole, 30 feet deep. It was as if the lake had been a giant bathtub and someone had pulled the plug.The lake's owner, Joseph Unanue, did indeed pull the plug. That's exactly what happened. The dam that held back the water to form the lake was falling apart, sogovernment officials ordered him to repair it. They issued him a permit to lower the dam level "five feet or more."He did much more. Mr. Unanue found repairs to the dam would cost $100,000. He didn't want to spend that much, so he opened the dam and lowered the water level until the lake was completely emptied. People living above the dam ended up with no lake. People living below the dam ended up with tons of mud and lots of dead fish. Everyone involved was angry with Mr. Unanue.Area residents believed Mr. Unanue acted out of spite（恶意）. They said he wanted to get back at them because the town wouldn't let him develop an amusement park on the lakeshore. When he couldn't build his park, he just went away and took his lake with him.(2)、The lake was compared to a bathtub because it could be emptied out.A错误B正确正确答案是：B。

现代大学英语精读4UNIT2翻译及课后答案
UNIT2历史学家们为什么意见不一大多数学生通常是通过一本厚厚的课本接触历史的，他们很快就被淹没在姓名、日期、时间和数据中。
然后学生的技能通过考试来检验，考试考的是他们记住了多少材料。
记得越多，分数就越高。
我们可以从中得出几条明显的结论：学习历史就是学习“史实”；作为历史专业的学生，知道的“史实”越多，你学得就越好。
专业的历史学家只不过是把大量的“事实”搜集在一起的人。
因此，当学生们发现历史学家们即使在研究同一事件时意见也有很大分歧的时候，他们常常感到困惑不解。
对于这种情况，学生们根据自己的常识作出的反应是，断定一位历史学家是正确的，而另一位是错误的。
而且，据此推测，错误的历史学家给出的“事实”是错误的。
然而，实际情况很少如此。
历史学家的论证通常很有道理，并且有说服力。
而且，“事实”——姓名、日期、事件和数据——常常是被证明是正确的。
此外，学生们还经常发现争论不休的历史学家对事实大致持相同意见；也就是说，他们使用大体相同的材料。
他们作出的结论不同，是因为他们看待过去的角度不同。
历史，本来已定就是记忆“史实”，现在变成了从众多解释中挑选一个令人满意的解释的事情。
历史的真相成为了个人偏好问题。
这种看法很难使人满意。
学生们肯定会想，对同一事件的两种完全不同的观点不可能同时是正确的；然而，他们没有能力在两者之间作出选择。
要了解历史学家们为什么意见不一致，学生们必须考虑一个他们或多或少认为是理所当然的问题。
他们必须问问自己，历史到底是什么。
从最广泛的意义上来说，历史指的是人类过去的总和。
比较狭义的概念是，历史是有记录的过去，即留下了某种记录的人类生活的一部分，比如民间故事、手工艺品或者有文字记载的文献。
最后，历史可以被定义为历史学家们书写的过去。
当然，这三种定义互相联系。
历史学家们的记述以过去人们的遗留物为根据；显然，他们不可能对所有的事情都了解，原因很简单，并不是每一件大小事件都被完整地记录下来了。
因此，历史学家充其量也只能接近历史。

Unit 2Text A技术与幸福Technology and Happiness詹姆斯·萨洛维奇PrefaceIn the present era, all of us are enthusiastically pursuing technological advancement and take it for granted that the development of technology will make us happier. However, little evidence can be found to prove the correlation between technology and happiness once material and technological advances reach a certain level. The text below may provide you with some insights into this issue.20世纪的美国人、欧洲人和东亚人都享受到了过去历代人都无法想象的物质和技术进步带来的乐趣。
譬如，在美国，从1950年到2000年国民生产总值翻了3倍。
人们的寿命大幅度提高。
二战后生产力的迅速发展使商品变得价廉物美。
诸如乘飞机旅游和打长途电话等曾经是奢侈的事情成了生活不可或缺的一部分。
In the 20th century, Americans, Europeans, and East Asians enjoyed material and technological advances that were unimaginable in previous eras. In the United States, for instance, gross domestic product per capita tripled from 1950 to 2000. Life expectancy soared. The boom in productivity after World War II made goods better and cheaper at the same time . Things that were once luxuries, such as jet travel and long-distance phone calls, became necessities. And even though Americans seemed to work extraordinarily hard, their pursuit of entertainment turned media and leisure into multibillion-dollar industries.那么，根据大多数标准衡量，你会说，现在的美国人比上个世纪中叶富裕多了。

2020年大学英语四级考试真题及解析（第二套）一、PartⅠWriting(30minutes)1.Directions:For this part,you are allowed30minutes to write an essay on the use of PowerPoint(PPT)in class.You can start your essay with the sentence“The use of PowerPoint is becoming increasingly popular in class”.You should write at least120words but no more than180words.输入答案内容...【答案】【参考范文】In recent years,using PPT is becoming increasingly prevalent among teachers while having classes.PPT can present knowledge in a clearer way, which will be more convenient for students to digest.And for teachers, PPT also rescues them from writing on the blackboard,which is sometimes a heavy work.Besides,PPT can be saved and copied for students to review after class.But for people who prefer the traditional class,they think PPT can never replace the blackboard.As when having class with PPT,students have less time taking notes.Meanwhile,some teachers say preparing PPT is very time-consuming and not efficient at all.From what has been discussed above,PPT does have strengths and weaknesses.But I believe it brings so much convenience for us that we can ignore the few weakness it has.And when using it,we can still take the blackboard as an aid so as to present the class in the best way.【审题构思】本次考查的话题“PowerPoint”贴近于生活，让考生就课堂使用PPT的现象，发表自己的看法。
新编大学英语4（第二版）课文翻译及课后答案详解
课内阅读参考译文及课后习题答案(Book 4)Unit 1享受幽默—什么东西令人开怀？1 听了一个有趣的故事会发笑、很开心，古今中外都一样。
这一现象或许同语言本身一样悠久。
那么，到底是什么东西会使一个故事或笑话让人感到滑稽可笑的呢？2 我是第一次辨识出幽默便喜欢上它的人，因此我曾试图跟学生议论和探讨幽默。
这些学生文化差异很大，有来自拉丁美洲的，也有来自中国的。
我还认真地思考过一些滑稽有趣的故事。
这么做完全是出于自己的喜好。
3 为什么听我讲完一个笑话后，班上有些学生会笑得前仰后合，而其他学生看上去就像刚听我读了天气预报一样呢？显然，有些人对幽默比别人更敏感。
而且，我们也发现有的人很善于讲笑话，而有的人要想说一点有趣的事却要费好大的劲。
我们都听人说过这样的话：“我喜欢笑话，但我讲不好，也总是记不住。
”有些人比别人更有幽默感，就像有些人更具有音乐、数学之类的才能一样。
一个真正风趣的人在任何场合都有笑话可讲，而且讲了一个笑话，就会从他记忆里引出一连串的笑话。
一个缺乏幽默感的人不可能成为一群人中最受欢迎的人。
一个真正有幽默感的人不仅受人喜爱，而且在任何聚会上也往往是人们注意的焦点。
这么说是有道理的。
4 甚至有些动物也具有幽默感。
我岳母从前经常来我们家，并能住上很长一段时间。
通常她不喜欢狗，但却很喜欢布利茨恩—我们养过的一条拉布拉多母猎犬。
而且，她们的这种喜欢是相互的。
布利茨恩在很小的时候就常常戏弄外祖母，当外祖母坐在起居室里她最喜欢的那张舒适的椅子上时，布利茨恩就故意把她卧室里的一只拖鞋叼到起居室，并在外祖母刚好够不到的地方蹦来跳去，一直逗到外祖母忍不住站起来去拿那只拖鞋。
外祖母从椅子上一起来，布利茨恩就迅速跳上那椅子，从它那闪亮的棕色眼睛里掠过一丝拉布拉多式的微笑，无疑是在说：“啊哈，你又上了我的当。
”5 典型的笑话或幽默故事由明显的三部分构成。
第一部分是铺垫（即背景），接下来是主干部分（即故事情节），随后便是妙语（即一个出人意料或令人惊讶的结尾）。

《现代大学英语听力4》听力原文及题目答案Unit-2
Unit 2Task 1:【答案】June 5th，the United Nations，1972，world leaders and citizens how to protect the environment，San Francisco, California，"Plan the Planet"，"Green Cities"，most people now live，more than 75 percent，the former vice president，music concerts，parades，tree plantings，representatives from many environmental organizations【原文】Every year on June fifth many countries celebrate World Environment Day. The United Nations established this special day in nineteen seventy-two to get people to think about taking care of the planet. Faith Lapidus tells us more.“Public events for World Environment Day are taking place from June first through June fifth. The events and conferences help teach world leaders and citizens how to protect the environment.“Every ye ar World Environment Day is celebrated in a different city. This year it is being held in San Francisco, California. This is the first time since the beginning of World Environment Day that the conference is being held in the United States. The main message of World Environment Day this year is ‘Plan for the Planet’. The events and conferences will show how to have ‘Green Cities’. This means that people will talk about ways that cities can have healthy environments.—“Most people in the world live in citi es. This makes them especially important areas of environmental concern. Cities use more than seventy-five percent of the world's natural resources such as water and gasoline. World Environment Day will center on how people in cities can work together to help save the planet.“San Francisco is holding public talks to discuss pollution reduction, clean energy sources and the importance of healthy parks and gardens. Special experts are among the speakers. For example, former vice-president Al Gore will talk about climate change. There also are fun events such as music concerts, movies, art shows, parades, bicycle rides and tree plantings. Local farmers and restaurant owners will serve food that has been naturally grown.“The Mayor of San Francisco, Gavin Newso m, invited city leaders from all over the world to attend this conference and share ideas. Representatives from many environmental organizations also are attending. The United Nations hopes to create an international agreement that countries and citizens w ill follow to help improve the Earth's environment.”Task 2:【答案】A.1) d^2) a4) cB.1) Occupational noise2) Aircraft noise3) Traffic noise$【原文】The sense of sound is one of our most important means of knowing what is going on around us. Sound has a wasted product, too, in the form of noise. Noise has been called unwanted sound. Noise is growing and it may get much worse before it gets and better.Scientists, for several years, have been studying how noise affects people and animals. They are surprised by what they have learned. Peace and quiet are becoming harder to find. Noise pollution—the crashing, squeaking, banging, hammering of people—is no joke. It is a threat that should be looked at carefully. Sound is measured in units called “decibels”. At a level of 140 decibels people feel pain in their ears.Automobiles, trucks, buses, motorcycles, airplanes, boats, factories, bands—all these things make noise. They bother not only our ears, but our minds and bodies as well. There is a saying ab out it being so noisy that you can’t hear yourself think. Doctors who study noise believe that we must sometimes hear ourselves think. If we don’t we may have headaches, other aches and pains, or even worse mental problems. Noise adds more tension to society that already faces enough stress. But noise is not a new problem. In ancient Rome, people complained so much about noise that the government stopped chariots from moving through the streets at night!Noise can be separated into a few general groups. The following examples are taken from hearings before the US Senate Subcommittee on Air and Water Pollution in 1970.Occupational noise—Factory workers who always hear noise have poorer hearing than other groups.Aircraft noise—Around airports or on air routes the noise of airplanes taking off and landing causes the greatest complaints.Traffic noise—Away from the noise of planes, traffic sounds break in on our peace and quiet. Trucks and motorcycles cause the most problems.|Task 3:【答案】1) F2) F3) T4) F5) T\6) F7) F9) T【原文】We usually think of pollution as a harmful waste substance that threatens the air and water. But some people have become concerned about another kind of pollution. It can be everywhere, depending on the time of day. And it was not thought of as a substance. It is light.The idea of light pollution has developed with the increase of lights in cities. In many areas, this light makes it difficult or impossible to observe stars and in the night sky. In 1998, the International Dark-Sky Association formed. This organization wants to reduce light pollution in the night sky. It also urges the effective use of electric lighting.There are a number of reasons why light pollution is important. One has become clear at the Mount Wilson near Los Angeles, California. Mount Wilson Observatory was home to the largest telescopes in the world during the first half of 1900.During that period, Los Angeles grew to become one of America's biggest cities.Today, light from Los Angeles makes the night sky above Mount Wilson very bright. It is no longer an important research center because of light pollution./Light pollution threatens to reduce the scientific value of research telescopes in other important observatories. They include Lick Observatory near San Jose, California and Yerkes Observatory near Chicago, Illinois.Light pollution is the result of wasted energy. Bright light shining into the sky is not being used to provide light where it is needed on Earth. Poorly designed lighting causes a great deal of light pollution. Lights that are brighter than necessary also cause light pollution.Recently, two Italian astronomers and an American environmental scientist created a world map of the night sky. The map shows that North America, Western Europe and Japan have the greatest amount of light pollution.Most people in America are surprised to find out that they are able to see our own galaxy, the Milky Way, with their own eyes. But about three fourths of Americans cannot see the Milky Way because of man-made light.Objects in the night sky are resources that provide everyone with wonder. And light pollution threatens to prevent those wonderful sights from being seen.Task 4:【答案】A.Israel and Jordan，365，the lowest point，saltiest，are important to Jews, Christians and Muslims，Minerals，The strange beauty of the seaB.Purpose of the project: To help save the Dead Sea from shrinking.—Countries to initiate the project: Israel and Jordan.Cause of the shrinking: Water that used to flow from the Jordan River into the Dead Sea has beenredirected for other uses in the area.Specific measures: A pipeline of more than 300 kilometers long will be built to pump water from the Red Sea through both countries into the Dead Sea.Duration of the project: At least three years.Cost of the project: 1,000 million dollars.Message sent by this project: The environment, ecology and nature are more important thanborders or political conflicts.C.1) T~2) T【原文】Israel and Jordan recently announced that they would work together to help save the Dead Sea from shrinking. Government officials said the joint project would help the sea, protect the area's unusual wildlife and increase the number of visitors to the area. The announcement was made during the United Nations World Summit on Sustainable Development earlier this month in Johannesburg, South Africa.The Dead Sea is on the border between Israel and Jordan. It is 365 meters below sea level. That is the lowest point on Earth. The Dead Sea is the saltiest large body of water in the world.The area around the Dead Sea has ancient places that are important to Jews, Christians and Muslims. Minerals in the Dead Sea are used for health treatments. The strange beauty of the sea brings many visitors to the area.But the Dead Sea is shrinking by almost one meter each year. Most of the water that flows into the Dead Sea comes from the Jordan River. However, water flowing from the Jordan River has been redirected for other uses in the area. Officials say within the next 50 years, the Dead Sea could shrink to less than half of its current size.To prevent that, Israel and Jordan plan to build a pipeline more than 300 kilometers long. The pipeline would pump water from the Red Sea through both countries into the Dead Sea. After the pipeline is built, the officials hope to build a canal and a salt removal System that will provide fresh water to Jordanians, Israelis and Palestinians.The pipeline will take at least three years to build. The project will cost as much as 1,000 million dollars. Israel and Jordan hope to pay for it with help from other countries. The project is expected to begin after a nine-month study is completed.^Israel and Jordan had hoped to cooperate closely on a number of issues after they signed a peace agreement in 1994. However, tensions have increased between them since the current Palestinian uprising began two years ago.Officials from Israel and Jordan described the water project as a major step forward. Experts say the agreement sends a message that the environment, ecology and nature are more important than borders or political conflicts.Task 5:【答案】A.1) 27 percent, higher ocean temperatures，activities by people，60 percent2) developing countries，off the coast of northeastern Australia，off the Philippines，the Caribbean islands，South America%B.Coral reefs support many kinds of sea life.Coral reefs also protect coastal communities in storms.Coral reefs support fishing activities and protect inland waterways.Coral reefs also have become popular stops for travelers.Corals are even important for medical research.C.1) F？2) T3) T【原文】Environmental experts are concerned about the world's coral reefs. A recent study found that twenty-seven percent of all coral reef systems have been destroyed. Experts believe higher ocean temperatures and activities by people are to blame. The study warns that sixty percent of the reef systems could be permanently lost if nothing is done to stop the problem.Corals are groups of small organisms called polyps. These polyps live within a skeleton made of a substance called limestone.Corals are found in warm waters. Millions of corals grow together to form coral reefs. Coral reefs are some of the oldest natural systems in the world. The reefs support many kinds of sea life. They can be to important to local and national economies. The reefs also protect coastal communities in storms.The World Wildlife Fund paid for the independent report. The group warns that the destruction of coral reefs will result in severe losses to the world economy. Peter Bryant works with the Endangered Seas Program of the World Wildlife Fund. Mister Bryant notes that most of the reef systems are in developing countries. He says the presence of coral reefs produces money for many economies.Coral reefs support fishing activities and protect inland waterways. They also have become popular stops for travelers. Many people like to swim underwater to see coral reefs. Mister Bryant estimates that the world's coral reefs are worth thirty-thousand-million dollars a year.{The largest in the world is the Great Barrier Reef off the coast of northeastern Australia. Coral reefs also are found in waters off the Philippines, Indonesia, the Caribbean islands, the United States and South America.Corals are even important for medical research. Mister Bryant says more than half of all new cancer drug studies involve sea creatures. For example, he notes there is a reef in the Caribbean with organisms that form the basis of the AIDS drug A-Z-T.The World Wildlife Fund say coral reefs should be declared protected areas. That way, human activities could be more closely supervised. The group says governments must take responsibility for the future of their coastal communities.Task 6:【答案】A.The group claims responsibility for hundreds of acts of destruction in the United States in the \past five years, with the destruction estimated at more than 30 million dollars. Since 1996, members of the group have claimed to have damaged or burned hundreds of new homes, tree- cutting companies, federal offices and animal and plant research laboratories. They say their goal is to stop development and other activities they consider harmful to nature. They say their property attacks are aimed at industry and rich people who profit from the destruction of the natural environment. The Earth Liberation Front says it will use any direct action necessary to carry out its goals. But it says it is opposed to harming animals or humans. Traditional environmental groups in the United States reject the group's methods.B.1) a 17-year-old student，the state of New York，cooperate with officials investigating the Earth Liberation Front2) environmental extremists，the group usually leaves very little evidence behind【原文】For years, American law enforcement officials have been trying to solve a series of environmental crimes. The crimes are linked to a group known as the Earth Liberation Front. The group claims responsibility for hundreds of acts of destruction in the United States during the past five years. The destruction has caused more than thirty million dollars worth of damage.Federal investigators say they are finally closer to solving the crimes. Recently, a seventeen-year-old student reportedly admitted setting a series of fires in the state of New York. He was charged in connection with acts of damage believed to be carried out by the Earth Liberation Front. The student is the son of a New York City police officer. He reportedly made the admission during a secret court hearing. As part of a deal, the student agreed to cooperate with officials investigating the Earth Liberation Front. He could face up to twenty years in prison.This is the first time that a member of the group has admitted being responsible for environmental crimes linked to the Earth Liberation Front. Three other suspects in the property attacks were negotiating with federal officials.Since Nineteen-Ninety-Six, members of the group have claimed to have damaged or burned hundreds of new homes, tree-cutting companies, federal offices and animal and plant research laboratories. They say their goal is to stop development and other activities they consider harmful to nature. They say their property attacks are aimed at industry and rich people who profit from the destruction of the natural environment.The Earth Liberation Front says it will use any direct action necessary to carry out its goals. But it says it is opposed to harming animals or humans. Traditional environmental groups in the United States reject the group's methods.The Earth Liberation Front includes environmental extremists who operate independently of each other. Federal investigators say their lack of structure has made them difficult to stop. And they say the group usually leaves very little evidence behind.A few weeks ago, the group claimed responsibility for burning several new homes inMount Sinai, New York. It has also claimed responsibility for destructive acts in Colorado, Arizona, Oregon and Wisconsin.Task 7:}【答案】A.renewable energy，the next ten years，1 percent，1,500 megawatts，past 20 years，38 cents，3 cents，a 90 percent drop，government supportB.A number of people who live on or visit the Cape say Cape Cod is a national treasure should not be open to industry. They argue that building the windmills would hurt fish and birds in the area, and it would hurt tourism. They say the windmills will ruin the beauty of looking out to sea from the coast.C.1) T2) F》【原文】A study says wind power will lead the growth in the use of renewable energy in the United States and Canada over the next ten years. Renewable energy also includes forms like power from the sun. Navigant Consulting in the United States carried out the study. Energy companies helped pay for much of the research.The use of wind energy has grown in the United States, but remains less than one percent of all the energy produced.Lisa Frantzis led the study. She says the researchers expect additions of as much asone-thousand-five-hundred megawatts from wind power projects each year. That is about equal to the energy production of one nuclear power station.The study says there have been major improvements in the performance of all renewable energy technologies in the past twenty years. For example, the study reports a ninety percent drop in the price of electricity produced from wind. In the nineteen-eighties a kilowatt hour of wind power cost about thirty-eight cents. Now, a kilowatt hour is closer to three cents.The study found that government support must continue and grow to permit renewable energies to compete in the power industry.However, some renewable energy companies face criticism. In fact, wind energy producers usually have to deal with opposition from communities they try to enter.Currently, a wind energy company is trying to set up business in Cape Cod, Massachusetts,in the northeastern United States. The Cape Wind company wants to place more thanone-hundred windmills in nearby waters. The windmills are hundreds of meters tall. Cape Windsays the project could provide Cape Cod with seventy-five percent of its electricity needs. And, it would not create pollution.'But, a number of people who live on or visit the Cape say they do not want the windmills. They say Cape Cod is a national treasure that should not be open to industry. They argue that building the windmills would hurt fish and birds in the area. And, they say it would hurt tourism. They say the windmills will ruin the beauty of looking out to sea from the coast.Environmental groups, however, look at the situation differently. They ague that a source of energy that does not cause pollution would protect natural environments like Cape Cod.Task 8:【答案】A.1) For him, pollution is the way environment is being misused, the actions which consume the environment, like the overuse of artificial fertilizers and over-cropping in developing agriculture. And the harmful substances like the waste from motor cars and factories are less important.2) They see pollution as a social problem, and the root cause of pollution is the way we organize our society and the incredible waste of resources.B.!1) Housewives can avoid buying things that they don't need.2) They can also cut down on the amount of packaging and try not to buy dyed toilet paper to reduce water pollution.3) People can avoid buying drinks in non-returnable bottles.4) They can reduce consumption by making their own food instead of buying it.【原文】Matthew: Christopher, most countries now appear to become increasingly concerned with the issue of pollution and its control. How do you see this problem Christopher: What I see as pollution is the way the environment is being mishandled. Um...obviously there are certain waste products which are vomited out of motor cars orout of factories, either into the sea or into the river ways and so on. But, you know,they are what people say is pollution. More important things, I think, in terms ofpollution, are the way that the environment in general is being misused. Thingslike agriculture, where artificial fertilizers and over-cropping and so on literallyconsume the environment. It is all picked up, collected, and transported from theland in terms of food or fibers and then ends tip in the sea at some stage, eitherthrough sewage or through waste products. I think that they are probably moresignificant.-Matthew: Right. Michael, can you tell me though whether.., urn.., as I get the feeling, this isa problem which has been blown up by the media, because people wish to avoidsome of the more difficult problems to do with being a consumer society,...and, ina sensei trying to solve many aspects of the pollution problem is rather a sort ofcleaning up process without getting to the root of the problemMichael: Well, pollution is a symptom really rather than the cause.Matthew: Mmm.Michael: But of itself it does produce many quite serious results. In fact we do not really know what the long-term effects of many pollutants are going to be, but mostforms of pollution can be solved.., urn.., fairly easily and usually by technicalmeans. Now the difficulty with other environmental problems is that many ofthem have no technical solution and this is where the difference arises betweenthose who are advocating technical solutions to problems which they see almostpurely in terms of pollution and those who see the real problems of society as awhole, the way we organize it, the incredible waste of resources that is endemicin this society.Matthew: This seems a very complex problem. Jane, how can individuals of the public, housewives, children at school, anyone.., help to prevent pollution Jane: Well, I think there are lots of things people can do in the home or at school or in the office. Mm... when it comes to tackling the problems on a major basis, Imean it's question of continual lobbying and pressuring, writing to newspapers,etc. But I think there are many things that people.., particularly housewives cando in the house, like urn.., for instance, just not buying things that have no useafter the package has been opened,.., um... to really make a note of the sort ofstuff that goes into the rubbish bin, that's very, very important; you can cut downon the amount of packaging.., on the amount of, for instance, water pollution likebuying um... toilet paper that's dyed... um.., and all this sort of thing that peoplecan cut down on. You can make a greater .effort not to buy drinks innon-returnable bottles; to make your own food, such as jams and drinks whichare quite easy to do, rather than just going out and buying and consuming moreand more. And if you put this into practice in all walks of life, in the home and atschool and in the office, this is a very, very good, major contribution to helpingsolve some of the more immediate problems of pollution.Matthew: So in a sense, perhaps you are saying that it's the way we consume things that is creating pollution, by the litter they cause or perhaps by the fact that we use somuch oil, and therefore there will be a number of oil tankers on the sea, and thatmeans there will be accidents and oil spillage and so on, so that we have to stopconsuming, is it...or...Jane: I think that is a very big part of it actually... Certainly, you know, when you get down to the more technical sides of pollution, of atmospheric pollution causedby certain industrial processes, there's not a great deal that an individual can doother than cause a fuss about it, which I hope most people, you know, wouldconsider doing. But certainly on a day by day household basis, much of theproblems of pollution are certainly caused by either just completethoughtlessness and waste or by problems of overconsuming natural resources.And in all the products that arrive at the housewife's table, the more refined andpre-packed and disposable it is, the more pollution it will have caused in itsmanufacture and it's likely to cause in its disposal【Task 9:【答案】I.

The important things to consider: The effects of this energy transition and theadvantages and the disadvantages of the new fuel.】【原文】Most industrialized nations have gone through two major energy transitions, and some nations are now making a third major energy transition. By energy transition we mean a change of one major resource of energy to another.The first major energy transition was from wood to coal. For many centuries people used wood as a primary source of energy. By burning wood people were able to heat their homes, cook their food, and produce basic items. By using wood societies were able to support themselves and take care of their needs. Most early societies grew up near a sufficient supply of wood. The main advantage of wood was that it was cheap and easy to get and easy to bum.During the early 1800s, probably around the year 1820, some towns and villages began to make transition from wood to coal as the basic source of energy. About that time, people thought that coal would have more advantages than wood. Wood is a renewable fuel, which means that it grows back. This is, an advantage. But most wood is not as efficient a source of energy as coal. Most wood doesn't burn for very long, and most wood doesn't burn at very high temperatures.It was found that coal could generally burn longer than wood. And it burned at a higher temperature. These were good points for industry because early in the 1800s industry began to develop very rapidly and a long-burning and hot-burning fuel was needed for the machines that were being used.Coal seemed to have another advantage. There was a lot of it, and it was easy to get. By digging just below the surface of the ground and by using simple tools, coal could be taken from the ground easily. In the 1800s transportation became more developed too, so coal could be shipped to faraway places. It was no longer necessary to live near a source of energy.Coal was used as a primary source of energy in many Western countries in the 1800s and the early 1900s. The transition from wood to coal seemed to have an overall effect. Industry developed. People were able to get more things, they were able to build bigger homes, and they were able to spend less time making what they needed for their daily lives. Most people would say that, in general, people's standard of living went up. People seemed to have lived a better life.After 50 years of using coal some disadvantages seemed obvious. One disadvantage was air pollution. Industrial centers of the early 1900s were often covered with a thick layer of smoke. Using coal was seen as somewhat unsafe and unhealthy.Another disadvantage of using coal was its rising costs. As more coal was used, it became harder to get. It became necessary to dig farther down in the ground in order to get the coal. Because coal was more difficult to get, the cost went up. And coal is a fossil fuel. It comes from under the ground. It doesn't renew itself. When it's gone, it's gone.At about the same time some of the disadvantages of coal became clear, petroleum began to reach the market. Petroleum became attractive because it was cheap and easy to get. Most。
