No wonder it is said that honesty is more precious than gold. It is a tie for people to maintain relationships of mutual trust, the cornerstone for the development and progress of human society.Honesty is the exterior expression of a citizen’s moral character, the crystallization of a variety of spiritual elements such as ethics, morality, ideology, culture, etc. To be honest and to keep one’s word, one must have a noble moral character. Toperfect one’s morality and behavior, one must be honest and dependable, and always keep one’s promise. Only when honesty is cherished as every citizen’s basic moral principle can the harmony of families and the prosperity of the country be guaranteed.Theme-Related WritingP256Sample Essay:My Understanding of Honesty and Success Different people have different opinion about the relationship between honesty and success.Some people believe that honesty and success are mutually exclusive. They regard honesty as a wasteful and costly investment that will only hinder success and prevent people from quick wins. Money-making tricks such as low-quality and fake products, or practices like plagiarism and bribery are seen as short-cuts to immediate success.However, many people hold that honesty and success are mutually supportive. They believe that honesty is the only means to an end. Being honest will definitely earn a person not only a good reputation, but also more opportunities to develop his or her career and ability. Honesty also helps cultivate an upright and healthy personality and brings people true pride and deep joy.I agree with the latter viewpoint. Honesty is a virtue that every one of us should value. It can bring out the best in a person and will give him or her the best reward. Those who are honest may suffer temporary losses sometimes, but they will benefit in the long run. In short, only by being honest consistently and persistently can we gain true and lasting success.。

Uint8II. Basic Listening Practice1.ScriptM:Scentists claim the world population has 99.5% of the same DNA.W: But this doesn’t tell us there is no such thing as race.Q: What is true of the DNA of difference races?2.ScriptW: With the advent of the genetic map we know where everything is, but do we know where to go with it?M: Your map seems to differ largely from my geographical map!Q: What does the man imply?3.ScriptM: As you know, it has taken millions of years of evolution and natural selection to get us where we are today.W: Yes, but now that we have genetic engineering, we seem to have decided that we want to be God.Q: What does the woman imply?4.ScriptM: I think the research into cloning will lead us into dangers, filling us with false hopes of perfection.W: It’s too late to turn back the clock. We’ll just have to depend on common sense to solve uncommon problems.Q: What does the woman mean?5.ScriptW: In America, many prisoners are having their cases reviewed, and some have even been freed through DNA testing.M: Except for the ones whose death sentence has already been carried out.Q: What can we learn about DNA testing from the dialog?Keys: 1.B 2.C 3.D 4.A 5.CIII. Listening InTask 1: Stem Cell ResearchScriptGregory: The Republican party in America is opposing stem cell research. I find ithard to believe that in this day and age, someone would do that.Lillian: Stem cell research sounds pretty impressiv e, I’ll admit. But just what is it? Gregory: Well, a stem cell is a special type of cell. It is a general cell that, when it devides, can become any specific type of cell.Lillian: You mean, a stem cell can become a heart cell? Or a brain or a kidney cell? Gregory: That’s about it. Stem cells are a part of the body’s maintenance and r epair system. When they divide, they can become any cell type.Lillian: I guess there would be some tremendous medical advantages in that sort of research.Gregory: You’ve said a mouthful. Recently, scientists were able to help a man who lost a jawbone for cancer. They recreated bone material for his jaw from stemcells. What it means is that since the new bone was created out of theperson’s own c ells, there was no problem with rejection because the DNAwas the same.Lillian: I bet the person was delighted. Why would anyone oppose that sort of research? It would seem to have endless potential to benefit the human race. Gregory: I agree, but there are people who think we should not interfere with nature and manipulate “what is natural”.Lillian: It’s easier to hold such a narrow view if you’re not in a position to need the benefits of the research. If you’re missing a jawbone because of cancer, youprobably support the research.1.What is the passage mainly about?2.Who is against stem cell research?3.What is special about a stem cell?4.When can a stem cell become another cell type?5.According to the passage, why do some people oppose stem cell research? Keys: 1.B 2.A 3.A 4.A 5.DTask 2: The Improvement of RiceScriptScientists now know a lot more about a grain that people have eaten for ten thousand years. (S1 Research teams around the world have completed a map of the (S2 genes of rices. The findings appeared last week in the (S3 journal Nature.The aim is to speed up the improvement of rice. The scientists (S4 warn that the kinds of rice plants used now have reached the limit of their (S5 productivity. Yet world rice production must (S6 grow by an estimated 30 percent in the next twenty to meet demand. By 2025, as many as 4.6 billion people will depend on rice for (S7 survival. There is a lot of pressure on breeders to improve the crop, and the rice genome is a valuable tool to do that. (S8 Plant breeders have already used preliminary information from the rice genome to create experimental strains of ricethat better resist cold and pests.The researchers also say rice is an excellent choice for genetic mapping and engineering. Rice genes have only about 390 million chemical bases. That maight sound like a lot. But other major food grains have thousands of millions. (S9 The new map could better explain more than just rice. Rice shares a common ancestor with other cereal crops. Because rice is the first cereal crop to be fully analyzed, researchers expect that sufficient knowledge of its genetic information will reveal the heredity of more complex grains, including corn, wheat and barley.(S10 While significant progress has been made in the analysis of the rice genome, the mapping of human genes is also making headway. When scientists can identify and manipulate genes that cause certain diseases, mankind will cure them easily. The human genetic map may help us control a person’s height, w eight, appearance and even length of life.Task3: The First Cloned CatScriptIn the age-old battle of cats and dogs, score one for the cats. Researchers at TexasA&M University recently announced that they have successfully cloned a cat name Rainbow—the first pet ever cloned—after several years of unsuccessful efforts to clone a dog name Missy.The ork, financed by a company hoping to provide pet-cloning services to wealthy owners, adds cats to a growing list of successfully cloned animals that includes pigs, sheep, cattle and mice.The success demonstrates cloning is a technology that could be transferred to other animal families as well. The accomplishment may provide new tools for studying diseases such as cats’ AIDS, a valuable research model for AIDS in humans. Research into animal cloning remains an important scientific alternative until the issue of human cloning is settled. And that seems unlikly in the immediate future, for it involves religious and moral principles. There are, for example, groups that insist no one should be allowed to take on the role of God the Creator.To create cloned cat embryos for the experiment, researchers transferred DNA from adult cat cells into egg cells stripped of their own genetic information. Out of 82 attempts with cloned embryos, one attempt resulted in a failed pregnancy, and another yielded a kitten named CC, delivered from a surroga te mother on December 22. The kitten’s name refers to “Carbon Copy” and “Copycat”, the name of the cloning project.Cloning attempts with dogs have proven unsuccessful in part becausedogs’reproductive cycles are more complicated.The technique may also work with endangered cats such as the African wildcat, fishing cat and blackfooted cat.Ironically, the increased knowledge of cat reproduction may best be suited fordeveloping cat contraceptives to control the U.S. cat population.1.Which of the following would be the best title for the passage?1.What did researchers at Texas A&M University recently announce?2.Which animals are NOT mentioned in the passage as having been cloned?3.According to the passage, why is human cloning unlikely to happen in the nearfuture?4.What does the passage say about the pregnancy and birth in cat cloning?Keys: 1.A 2.B 3.C 4.B 5.CIV. Speaking OutMODEL 1 Why are people protesting againstgenetically modified foods?Susan: With so many people suffering from malnutrition around the world, why are people protesting against genetically modified foods?Chris: Some people are protesting about genetically modified foods, but even more people are protesting the fact that processed foods containing these ingredients aren’t labeled.Susan: But why should they be labeled?Chris: Not everyone is sure that genetically modified foods are safe. They want to be certain that biotech foods have the sme composition as organic foods. Susan: But there are more urgent problems in this world. Many people are dying of starvation.Chris: But those who aren’t starving may want genetically modified foods to be labeled so they know what foods they should andd shouldn’t eat.Susan: Y ou know, I heard of a genetically modified fish that grew to be ten times its normal size.Chris: That sure sounds abnormal.Susan: Yeah, it does sound a bit strange , but that fish could feed ten times as many people.Chris: You’re right; genetically modified food might help solve world hunger. But I think we have a right to know what we are eating.MODEL2 Do you think the cloning of humansshould be forbidden by law?ScriptSusan: After the cloning of Dolly the sheep, I think human cloning is next.John: Whoa. I have some reservations about it. There are stll many scientific problemsto solve before human cloning starts.Susan: There’s an easier way. The Clonaid Company says they’ve cloned humans. John: Oh, my God! These guys claim aliens from another planet taught them human cloning.Susan: A woman gave them half a million dollars to clone her dead daughter. John: Clearly that woman doesn’t know much about cloning. How r isky it is! Susan: I knowit’s inefficient. It took 276 tries to produce Dolly. But why is it risky? John: Cloned animals grow abnormally large and age unnaturally fast.Susan: In other words, that woman may not be happy with her cloned daughter. John: Then there are the emotions. No one knows if cloning damages the mind. Susan: Do you think the cloning of humans should be forbidden by law?John: To my mind, t he cloning of human organs shouldn’t be prohabited. It may help solve medical problems.Susan: I see your point: cloning should be regulated if it’s to benefit humanity.MODEL3 Is it interfering with nature?ScriptNora: Some religious groups are opposed t o genetic research. They believe it’s interfering with nature.John: I know. But nature can be pretty hard-nosed too, so we often need to interfere with her—we build dams to control flooding.Nora: There’re many diseases that are a part of nature, and they cause people a great deal of misery: cancer and diabetes, for example.John: A better understanding of the genetic code that controls our body would be a great help in curing many diseases.Nora: The project to map the human genetic code…what’s that calle d?John: The genome project. As you say, it has tremendous promise to make our lives better—just in the ability to identify and correct genetically-caused diseases like Alzheimer’s.Nora: Some diseases like cancer are also believed to have a genetic switch.John: That’s right, and once researchers identify the switch, perhaps they can turn of f cancer or Alzheimer’s.Nora: People are also concerned that science will enable us to determine such qualities as intelligence and height.John: You know it’s going to happen—it’s just a matter of when.Nora: Imagine if everyone was a combination of Yao Ming and Albert Einstein. John: But what if they get it wrong, and you wind up with Yao Ming’s knowledge of nuclear physics and Albert Einstein’s height?Nora: All those religious groups would say that it served you right.Now Your TurnTask 1SAMPLE DIALOGJane: Some countries are suffering from crop failure and famine, but why do they refuse genetically modified crops and foods?Bob: And many Europeans insist that processed foods containing GM ingredients be labeled.Jane: Why should they be labeled?Bob: Not everyone is sure that genetically modified foods are safe. They want to certain that biotech foods have the same composition as traditional foods. Jane: But there are more urgent problems in this world. Many people are dying of famine.Bob: But tho se who aren’t hungry may want all genetically modified products to be labeled so they know exactly what they’re eating.Jane: You know, I’ve heard of a GM fish that was ten times larger than a normal fish. Bob: That really sounds abnormal.Jane: Some famine-stricken people are afraid GM crops will overpower and eliminate their native crops.Bob: Sounds alarming.Jane: Yeah, but GM foods can feed many people.Bob: You’re r ight; they could solve the problem of starvation in the world. But I think we have a right to know what we are eating. GM food should be labeled. V. Let’s TalkScriptCorrespondent: In the U.S. what percentage of people support biotech crops? Anddo those who support biotech crops also eat biotech foods? Whatpercentage of food on the market has genetically modifiedingredients?Professor: U.S. consumers have been exposed to a very effective anti-biotechnology propaganda campaign for the last few years, butaccording to polls, over 70% support biotechnology. For example, ina recent referendum in Oregon, voters rejected a proposal to requirespecial labels on all products containing biotech ingredients by anoverwhelming 73% to 27%. That’s probably because c onsumersknow that we have an effective administrative system. Many mayalso know that 70-80% of the processed food products onsupermarket shelves contain one or more ingredients from biotechcrops. All Americans eat biotech foods unless they deliberately seekout products that are labeled otherwise. Evidence suggests that thisis less than 5% of consumers.Correspondent: Chinese scientists have used biotechnology to create a new type of tomato, which contains the vaccine against hepatitis B. What’s yourtake on this?Professor: It’s a great example of how this technology can be used to save lives, ease pain and suffering and improve the human condition. How cananyone be opposed to that? My only hope is that the clinical trials ofthis new tomato go well, and that it is quickly delivered tohealth-care providers who will use it to vaccinate people againsthepatitis. By the way, please note that I do think that such newpharmaceutical foods need to be handled as medicines byprofessionals and not as conventional foods. You will never seethese tomatoes in the supermarket. In a sense, the tomato plant isjust being used to manufacture a vaccine in a very safe andeconomical manner.VI. Further Listening and SpeakingTask1: Confident enough to control your fate?ScriptSome people are born with the belief that they are masters of their own lives. Others feel they are at the mercy of fate. New research shows that part of those feelings are in the genes.Psychologists have long known that people confident in their ability to control their fates are more likely to adjust well to growing old than those who feel they drift on the currents of fate.Two researchers who questioned hundreds of Swedish twins report that such confidence, or lack of it, is partly genetic and partly drawn from experience.They also found that the belief in blind luck—a conviction that chance plays a big role in life—is something learned in life and has nothing to do with heredity.The research was conducted by Nancy Pedersen, a professor of psychology at the University of Southern California in Los Angeles. The results were recently published in the United States in the Journal of Gerontology.People who are confident of their ability to control their lives have an “internal locus of contro l”, and have a better chance of being well adjusted in their old age, said Pedersen. An “external locus of control”,believing that outside for ces determine the course of life, has been linked to depression in latter years, she said.“We are trying to unde rstand what makes people different. What makes some people age slowly and others have a more difficult time?” she said.The study showed that while people have an inborn tendency toward independence and self-confidence, about 70 percent of this personality trait is affected by a person’s environment and lifetime experiences.Pedersen’s studies, with various collaborators, investigate the aging pr ocess by comparing sets of twins, most of whom were separated at an early age.The subjects were drawn from a list first compiled about 30 years ago, registering all twins born in Sweden since 1886. The complete list, which was extended in 1971, has 95,000 sets of twins.1.Which of the following is concerned with blind luck?2.Which of the following is related to an external locus of control?3.According to the passage, what is true of one’s inborn tendency towardsself-confidence?4.What subjects were mostly use d in Pedersen’s studies?5.What is the main idea of the passage?Keys: 1.A 2.B 3.C 4.C 5.DTask 2: Is it moral to clone humans?ScriptLaura: Did you hear about that peculiar cult that claimed to have created the world’s first human clone?Ian: Yeah, I did! They also said that it was aliens that created life on earth over 25,000 years ago. What are they on?Laura: I know! It was so obviously just part of an elaborate hoax to bring publicity to their crazy movement. But I don’t think the truth can be fa r off. Scientists have been working on it for years.Ian: Sure, but most scientists are working on cloning human cells or body parts that can be used to repair or replace damaged organs. Not complete human beings! That’s just science fiction!Laura: Well, the science may seem to be very advanced, but the idea is not a new one.In A Journey to the West, Sun Wu-kung, the Monkey King, can clone himself from the hairs on his head. He just plucks a few hairs, chews them a bit, and when he spits them out, they change into replicas of him!Ian: Really? Now that would be cool! You could send your clone to school while you went to the cinema, and then it could do your homework! Wow! Now thatI think of it, it would be kind of fun to have a clone!Laura: You would say that! Don’t you think it’s slightly immoral? I mean, it’s just like having a slave. Doesn’t the clone deserv e a life of his own?Ian: Sure, but human beings must learn to strike a balance between the welfare ofa patient and of a clone.Keys: 1.T 2.T 3.F 4.F 5.TTask3: A Drunkard’s ArgumentScriptHere’s drunkard’s argument in favor of heavy drinking.We would learn more about human bihavior if we paid closer attention to the laws at work in the animal kingdom.“Only the fittest survive” is a law that is apparent everywhere in the natural world. Human beings could certainly benefit from a close study of how this law operates among, for example, the wild buffalo.A herd of buffalo moves only as fast as the slowest buffalo. When the herd is hunted, it is the slowest and weakest animals at the back that are killed first. This is naturalselection, and it is good for the herd. The general speed and health of the group keeps improving with regular killing of the weaker memebers.The same process of survival of the fittest is to be observed by looking closely at the human brain, which can operate only as fast as the slowest brain cells. Excessive consumption of alcohol, as we all know, kills brain cells. Just like the less vigorous buffalo at the back of the herd, the weakest and slowest brain cells are destroyed first. In this way the principles of natural selection become evident. Regular consumption of large amounts of beer eliminates the weaker brain cells, making the brain a faster and more efficient machine. It is therefore not suprising that one also feels smarter after drinking several glasses of beer.News ReportBioinformaticsScriptIt’s a complex name for a complex subject. Bioinformatics is the key to figuring out the wealth of information in the human genome project.Researchers have nearly mapped out all of the 30,000 genes that make up human DNA, but making sense of useful data is not easy.The company Double Twist is a pioneer in the business of bioinformatics. [SOUND BITE]Double Twist works mainly with information that is also available to thepublic,sifting through data to find what may help link a biological problem like cancer, to its possible cure.[SOUND BITE]The company then sells software and data to pharmaceutical companies, biotech companies, and academic institutions, which use them in their work. This provides a solution to help people better understand data from the human genome project. [SOUND BITE]Bioinformatics speeds up drug development and provides more accurate research.[SOUND BITE]Human Genome Sciences takes the process one step further. It uses bioinformatics to develop drugs using its own genomic information.[SOUND BITE]Right now, Human Genome Sciences has four new drugs being tested that are the results of genomic research. Bioinformatics systems developed within the company played an important role in discovering these drugs.[SOUND BITE]Bioinformatics can also bring much quicker returns for investors.[SOUND BITE]Even though its role is crucial, bioinformatics if only a small part of the overall $305 billion biotech sector, accounting for only about $2.23 billion. But some investors believe that bioinformatics has great potential. ［SOUND BITE］ So unless drug companies start developing their own bioinformatics systems or partner with companies that can provide them, they may get left behind in the race to discover new drugs.。

Parents think that they know their children well enough to decide what kind of job suits them. They are afraid that their children are too young to decide their future on theirown. However, many children would argue that they should be left free to make their own choices.The other aspect of career choice is that parents and their children are often different in their opinions of the ideal profession.

On the stage he often wore tiny moustaches, huge pants and tailcoats that were perhaps more characteristic of Europeans and may be not much of the British.

With sound movies, Chaplin created a nonsense language that had no known nationality and was accepted and appreciated by people all over the world.

Under the new welfare system, the law encourages welfare clients to work on their own for a gradual shift away from welfare, and this is not the case in the past. Welfare clients now can develop their talents to make money. In the past, they often cheated to bleed the system for a few extra dollars. Now caseworkers will gladly helptheir clients find appropriate jobs rather than act like detectives to try to seek out any unreported properties. Today many welfare clients have made a choice to live a life of complete honesty and they tell the truth to caseworkers and declare any extra income they make. In cases like this, caseworkers will feel greatly relieved because they don't need to search for any cheating as in the past.新版新视野大学英语读写教程第四册unit5答案unit 5III.1. humble2. slippery3. tame4. inspiration5. crept6. apology7. observation8. dictate9. inadequate 10. solitary Exercises on Web course only:1l. choked 12. waterproof 13. poetry 14. commodityIV1. cast out2. all by himself3. stay up late4. was fond of5. at one sitting6. filled up with7. speaks highly of8. set forth9. at length 10.for the time beingV.1.K2.H3.M4.B5.A6.07.J8.D9.F 10.1 CollocationVI.1. efficiency2. status3. performance4. standard5. coordination6. sense7. career8. quality9. supply 10. accuracy Word Cjuifdin8VIl.1. underestimated2. underpaid3. overslept4.

Literary giants such as William Wordsworth, John Milton and Henry Thoreau enjoyed living alone on purpose. Hunters or explorers enjoy themselves as they venture out to tame the great wild areas. On the other hand, there are some other people who have to live alone due to various reasons: being divorced, widowed or never married. Many of them feel bitter to live in solitude. They have no one to talk to and as a result they talk at length to themselves and to their pets and to the television.can actually be the master of it.新版新视野大学英语读写教程第四册unit6答案Unit 6Section AIII.1.

They believe in the inspiration in solitude. One of my friends is a writer. He enjoys the time when he is alone because he can stay up late to read and, above all, concentrate on his writing without fear of being interrupted by others. On his wall he posts a quotation from Thoreau: "I never found the companion that was so companionable as solitude." The second group consists of people who are disappointed with their marriage or family life. A woman I know has been living alone since her husband left her five years ago. She is not waiting for his return but she is just disappointed with life.新版新视野大学英语读写教程第四册unit7答案unit 7III.1. discounted2. biased3. variation4. potential5.

The negotiations had been going on for months without any real results. He was at his wits' end. Finally, he hit upon a solution. One day he bought a popular novel and slipped a check of ￡20,000 in the book. Then he presented it to the minister in charge of transportation. This minister examined its contents, pretending he didn't see the check at all. Then he said with a smile:” Young man, I hear London is at its best in May.“The sales manager, who was quick-witted, replied: "My company in London will be most honored to welcome your visit!"

For questions 1-7, choose the best answer from the four choices marked A, B, C and D. For questions 8-10, complete the sentences with the information given in the passage.Questions 1 to 10 are based on the same passage or dialog.SwimmingSwimming is a technique to move unaided through water. This article concentrates on human swimming, a popular recreational activity and a competitive sport. There are many health benefits of swimming, but it also has risks.TechniqueAre you a good swimmer? Can you swim at all? With practice, technique can convert a slow or average swimmer to at least a moderately fast swimmer. Since speed converts directly into distance, the same techniques that improve speed also aid one to move farther with the same effort. The upper body and the legs should be kept as much as possible parallel to the surface of the water. Dropped legs or a lowered upper body dramatically increase drag. The hand should be extended forward of the head as much as possible. This increases the average length at the water-line, substantially increasing speed. This is an effect long used by boat designers, and unconsciously used by "naturally good swimmers".Competitive swimmingCompetitive swimming is swimming with the goal to maximize performance, usually the speed of swimming. Competitive swimming became popular in the 19th century, and currently comprises 32 events, 16 male events, and 16 female events, at the Summer Olympic Games. The Competitive international governing body of swimming events is the International Swimming Association. It is currently being debated whether or not to include the 1500m freestyle as part of the female events. Currently, the longest female event is the 800m freestyle.Recreational swimmingThe most common reason for swimming is probably recreation, where the swimmer enters the water merely for enjoyment. Swimming is a good way to relax. Many swimming styles are suitable for recreational swimming. Most recreational swimmers prefer a style that keeps their head out of the water and uses an underwater arm recovery. Most recreational swimming takes place in pools, where the water is calm. Therefore Freestyle (which does not work as well in rough water) is suitable. However, playing around in rough water is a common source of recreation, but is sometimes dangerous due to the risk of injury from rocks on the bottom of a lake or riverbed. Swimming pools are popular places for recreational swimming, as are beaches, lakes, swimming holes, rivers, and sometimes canals.Occupational swimmingA number of people enter the water and swim as part of their work,fishermen for example, who might dive into the water and swim for economic benefit.Swimming is used to rescue other swimmers who are in distress. There are a number of specialized swimming styles specifically for rescue purposes. Such techniques are studied by lifeguards or members of the Coast Guard. The training of these techniques also evolved into competitions such as surf lifesaving.Swimming is also done for scientific research. Swimming is studied to improve the performances of competitive swimmers. Swimming is also used in marine biology to observe plants and animals in their natural environment. Other sciences may also use swimming. Konrad Lorenz for example swam with geese as part of his studies of animal behavior.Swimming also has military purposes besides the mere need to cross waters. A swimmer in the water or under the water can be difficult to detect, especially at night. Military swimming is usually done by Special Forces, especially ones in the Navy. Swimming is used to approach a location, gather intelligence, or combat, and to depart a location. This may also include dropping into water from an airplane or jumping in from a boat. Special equipment and techniques are also used to fight with others in and under water.Swimming for exerciseSwimming is a good form of exercise. Because the density of the human body is approximately similar to that of water, the body is supported by the water and less stress is therefore placed on joints and bones. Furthermore, the resistance against movement depends heavily on the speed of the movement, allowing the fine tuning of the exercise according to one's ability. Therefore, swimming is frequently used as an exercise after injuries or for the disabled.Resistance swimming is one form of swimming exercises. It is done either for training purposes, to hold the swimmer in place for stroke analysis, or to enable one to swim in a confined space for athletic reasons. Resistance swimming can be done either against a stream of water set in motion by a (usually) self-contained mechanical device (often termed a swimming machine) or by holding the swimmer in one place by means of elastic attachments.Swimming is primarily an aerobic (有氧的) exercise due to therelatively long exercise time, requiring a constant oxygen supply to the muscles, except for short sprints. As with most aerobic exercise it is believed to reduce the harmful effects of stress. While aerobic exercises usually burn fat and help with losing weight, this effect is limited in swimming, even though being in cold water burns more food energy to maintain body temperature.The reason that swimming does not significantly reduce weight is still poorly understood, but seems to be related to the better heat conduction of water. A number of reasons are suspected. Firstly, water cools the body much faster than air, and most researchers believe that subsequently the body aims to maintain a layer of fat under the skin to keep the body's temperature at a stable level. Secondly, it is believed that appetite decreases as your body temperature increases, as for example during exercise. However, during swimming the body is cooled down almost instantly as the surrounding water is usually cooler than the body temperature, and some researchers believe that this may actually increase the appetite. This assumption is not yet proven by research. Thirdly, fast swimming requires a high level of effort, meaning sugars rather than fats are burned. Long-lasting exercise at lower intensity is better for fat-burning. Fourthly, some researchers also believe that the energy-burning systems of the body increase at higher body temperature, burning more food energy. Again, during swimming the body is cooled down by the surrounding water, reducing the activity of these energy-burning systems, and subsequently the amount of food energy burnt. This assumption is also not yet proven by research. Finally, there is also a theory that people with a genetically higher body fat content tend to be more successful as swimmers since the increased fat aids in keeping them on the surface of the water. Being fat may also help because rounder shapes offer less resistance to the water.Swimming exercises almost all muscles in the body. Usually, the arms and upper body are exercised more than the legs. In competitive swimming, excessive leg muscles can be seen as a disadvantage as they consume more oxygen, which would be needed for the muscles in the arms, although this depends on the swimming style. While some swimming styles generate significant movement with the legs, some other methods employ mainly the arms.1.From the first paragraph we know that swimming________________.A. is a technique with the help of waterB. has quite a lot of advantages but no riskC. is a technique, a sport and a recreational activityD. needs concentration and has health benefits2.What is the practical function of technique according to thepassage?A.

Apart from these sciences is philosophy. In the first place, pure or theoretical knowledge has been sought only for the purpose of understanding. What distinguishes man from animals is that he knows and needs to know. If man did not know that the world existed, and that the world was of a certain kind, that he was in the world and that he himself was of a certain kind, he wouldn't be man. The technical aspects or applications of knowledge are equally necessary for man and are of the greatest importance, because they also contribute to defining him as man and permit him to pursue a life increasingly more truly human.But even while enjoying the results of technical progress, he must defend the value of pure knowledge. Knowledge sought directly for its practical applications will have immediate and foreseeable success, but pure or theoretical knowledge will not. Let me recall a well-known example. If the Greek mathematicians had not applied themselves to the investigation of conic (圆锥形的) sections, keenly and without the least suspicion that it might someday be useful, it would not have been possible centuries later to navigate far from shore. The first men to study the nature of electricity could not imagine that their experiments, carried on because of mere intellectual curiosity, would eventually lead to modern electrical technology, without which we can scarcely think of contemporary life. Pure knowledge is valuable for its own sake, because the human spirit cannot resign itself to ignorance. But, in addition, it is the foundation for practical results that would not have been reached if this knowledge had not been sought disinterestedly.1.The most important advances made by mankind come from________ according to the passage.A. practical applications of social sciencesB. practical applications of pure knowledgeC. sciences dealing with the natural worldD. the biological sciences2.The author does NOT include among the sciences the study of_________.A. chemistryB. astronomyC. economicsD. literature3.The author points out that the Greeks who studied conicsections ________.A. were mathematiciansB. were interested in navigationC. were unaware of the practical value of their studiesD. worked with electricity4.The title below that best expresses the ideas of this passage is________.A. Technical ProgressB. A Little Learning Is a Dangerous ThingC. Man's Distinguishing CharacteristicsD. The Value of Pure Knowledge5.Pure knowledge is valuable for its own sake because________.A. it is sought only for the purpose of understandingB. it is the foundation for practical resultsC. people are keen on itD. people are curious about itQuestions 6 to 10 are based on the same passage or dialog. Are organically grown foods the best food choices? The advantages claimed for such foods over conventionally grown and marketed food products are now being debated. Advocates of organic foods—a term whose meaning varies greatly—frequently proclaim that such products are safer and more nutritious than others.The growing interest of consumers in the safety and nutritional quality of the typical North American diet is a welcome development. However, much of this interest has been sparked bysweeping claims that the food supply is unsafe or inadequate in meeting nutritional needs. Although most of these claims are not supported by scientific evidence, the great number of written material advancing such claims makes it difficult for the general public to separate fact from fiction. As a result, claims that eating a diet consisting entirely of organically-grown foods prevents or cures disease or provides other benefits to health have become widely publicized and popular among customers.Almost daily the public is surrounded by claims for "no-aging" diets, new vitamins, and other wonder foods. There are numerous unsubstantiated (无确实根据的) reports that natural vitamins are superior to synthetic ones, that fertilized eggs are nutritionally superior to unfertilized eggs, that untreated grains are better than fertilized grains, and the like.One thing that most organically grown food products seem to have in common is that they cost more than conventionally grown foods. But in many cases consumers are misled if they believe organic foods can maintain health and provide better nutritional quality than conventionally grown foods. So there is real cause for concern if consumers, particularly those with limited incomes, distrust the regular food supply and buy only expensive organic foods instead.6.The word "Advocates" (Para. 1) is closest in meaning to whichof the following?A. Supporters.B. Merchants.C. Inspectors.D. Consumers.7.What does the word "others" (Para. 1) refer to?A. Advantages.B. Advocates.C. Organic foods.D. Nonorganically-grown products.8.The author implies that there is cause for concern if consumerswith limited incomes buy organic foods instead ofconventionally grown foods because ________.A. organic foods can be more expensive but are often no betterthan conventionally-grown foodsB. many organic foods are actually less nutritious than similarconventionally-grown foodsC. conventionally-grown foods are more readily available thanorganic foodsD. too many farmers will stop using conventional methods togrow food crops9.According to the last paragraph, consumers who believe thatorganic foods are better than conventionally-grown foods are often ________.A. carelessB. mistakenC. mistakingD. wealthy10.What is the author's attitude toward the claims made byadvocates of health foods?A. Very enthusiastic.B. Somewhat favorable.C. Neutral.D. Doubtful.Part 4 Reading Comprehension (Multiple Choice)(每小题: 3 分; 满分：30 分)(In the case of True/False type of questions, A stands for True and B for False, or A for Y, B for N and C for NG.)小题得分对错学生答案Correct1. 3 B (To be shown in 1 day.)2. 3 D (To be shown in 1 day.)3. 3 C (To be shown in 1 day.)4. 3 D (To be shown in 1 day.)5. 3 B (To be shown in 1 day.)6. 3 A (To be shown in 1 day.)7. 3 D (To be shown in 1 day.)8. 3 A (To be shown in 1 day.)9. 3 B (To be shown in 1 day.)10. 3 D (To be shown in 1 day.)Subtotal: 30=> 就此结束考试，返回我的课程返回我的课程。
