As a result of this new awareness, attitudes towards health are changing. In the past, people tend to think that it was 44 for good health to have a good doctor who could be relied on to know exactly what to dowhen they become ill. Now they are realizing that merely receiving the best treatment 45 illness and injury is not enough. They are learning that they must 46 more responsibility for their own health.Today many people are changing their dietary 47 and eating food with less fat and cholesterol. Many are paying more attention to reducing 48 in their lives. The number of smokers in the US is now far below the level of a lot of years ago 49 many people succeed in breaking the habit and as fewer people take it up.More and more are aware of the 50 of regular exercise like walking, running or swimming, some have begun to walk or ride bicycles to work instead of driving. Millions have become members of health clubs and have 51 health club one of the fastest growing businesses in the US today.And now the beneficial effects of these changing attitudes and behaviors are beginning to appear: an encouraging decrease in deaths from heart disease.PART ⅤREADING COMPREHENSIONSECTION A MULTIPLE-CHOICE QUESTIONSIn this section there are several passages followed by ten multiple-choice questions. For each question, there are four suggested answers marked A, B, C and D. Choose the one that you think is the best answer and mark your answers on ANSWER SHEET TWO.PASSAGE ONE"There is very little in my life that is more personal and more important to me than comets." The amateur astronomer David H. Levy told Terence Dickinson in an interview. "Not just discovering them but watching them, learning about them, writing about them, understanding what they do. It makes observing the sky intensely personal. I feel when I find a new comet that a door has been opened and I have seen a slightly new aspect of nature. There is this object in the solar system that —for a few minutes or a few hours—only I know about. It is like trying to pry a secret out of nature. It is a very special feeling."Ever since he was a child, David Levy has been fascinated by the night sky and the wonders it reveals to devoted watchman. He developed a special feeling for comets before he reached his teens, though it was not until 1984—after nineteen years and more than nine hundred hours of combing the sky in search of them—that he discovered his first one, from a small observatory that he had built in his backyard.Since then, he has discovered or co-discovered twenty more, making him one of the world's most important comet hunters. His most celebrated find is periodic comet Shoemaker Levy 9, which he made with the husband-and-wife comet and asteroid hunting team Eugene and Carolyn Shoemaker. The comet's dramatic collision with Jupiter in July 1994, which constituted "the greatest planetary show in recorded history", to quote Malcolm W. Browne of the New York Times, captivated not only professional astronomers, but many amateurs. Although he is "only" an amateur astronomer, he earns his living by lecturing and writing books and by working with project artists. They're projects devoted to introducing astronomy toelementary school children. He has won tremendous respect from his professional colleagues for his success in tracking comets. "David Levy is one of those rare individuals blessed with the gift of discovery," David Hartsel, who serves on the board of directors of the Richland Astronomical Society, in Ohio, has said. "Even rarer is his ability to let others share in the excitement and wonder of those discoveries through his writing and lectures."PASSAGE TWOBeing a man has always been dangerous. There are about 105 males born for every 100 females, but this ratio drops to near balance at the age of maturity, and among 70-year-olds there are twice as many women as men. But the great universal of male mortality is being changed. Now, boy babies survive almost as well as girls do. This means that, for the first time, there will be an excess of boys in those crucial years when they are searching for a mate. More important, another chance for natural selection has been removed. Fifty years ago, the chance of a baby (particularly a boy baby) surviving depended on its weight. A kilogram too light or too heavy meant almost certain death. Today it makes almost no difference. Since much of the variation is due to genes, one more agent of evolution has gone.There is another way to commit evolutionary suicide: stay alive, but have fewer children. Few people are as fertile as in the past. Except in some religious communities, very few women have 15 children. Nowadays the number of births, like the age of death, has become average. Most of us have roughly the same number of offspring. Again, differences between people and the opportunity for natural selection to take advantage of it have diminished. India shows what is happening. The country offers wealth for a few in the great cities and poverty for the remaining tribal peoples. The grand mediocrity of today—everyone being the same in survival and number of offspring—means that natural selection has lost 80 percent of its power in upper-middle-class India compared to the tribes.For us, this means that evolution is over; the biological Utopia has arrived. Strangely, it has involved little physical change. No other species fills so many places in nature. But in the past 100,000 years—even the past 100 years—our lives have been transformed but our bodies have not. We did not evolve, because machines and society did it for us. Darwin had a phrase to describe those ignorant of evolution: They "look at an organic being as a savage looks at a ship, as at something wholly beyond his comprehension". No doubt we will remember a 20th century way of life beyond comprehension for its ugliness. But however amazed our descendants may be at how far from Utopia we were, they will look just like us.PASSAGE THREEBy far the most common difficulty in study is simple failure to get down to regular concentrated work. This difficulty is much greater for those who do not work for a plan and have no regular routine of study. Many students muddle along, doing a bit of this subject or that, as the mood takes them, or letting their set work pile up until the last possible moment.Few students work to a set timetable. They say that if they did construct a timetable for themselves they would not keep to it, or would have to alter itconstantly, since they can never predict from one day to the next what their activities will be.No doubt some temperaments take much more kindly to a regular routine than others. There are many who shy away from the self-regimentation of a weekly timetable, and dislike being tied down to a definite program of work. Many able students claim that they work in cycles. When they become interested in a topic they work on it intensively for three or four days at a time. On other days, they avoid work completely. It has to be confessed that we do not fully understand the complexities of the motivation to work. Most people over 25 years of age have become conditioned to a work routine, and the majority of really productive workers set aside regular hours for the more important aspects of their work. The "tough-minded" school of workers is usually very contemptuous of the idea that good work can only be done spontaneously, under the influence of inspiration.Those who believe that they need only work and study as the fit takes them have a mistaken belief either in their own talent or in the value of "freedom". Freedom from restraint and discipline leads to unhappiness rather than to "self-expression" or "personality development". Our society insists on regular habits, time keeping and punctuality, and whether we like it or not, if we mean to make our way in society we have to comply with its demands.PASSAGE FOUREven just a degree or two of greenhouse warming will have a dramatic impact on water resources across western North America. Teams who have modeled the climate in the area are warning of greatly reduced snow packs and more intense flooding as temperatures inch up during the 21st century.It's the first time that global climate modelers have worked so closely with teams running detailed regional models of snowfall, rain and stream flows to predict exactly what warming will do to the area. The researchers, from the National Center for Atmospheric Research in Boulder, Colorado, and elsewhere, were surprised by the size of the effect generated by only a small rise in temperature.Assuming business as usual emissions, greenhouse gases will warm the west coast of North America by just one or two degrees Celsius over the next century, and average precipitation won't change much. But in the model, warmer winters raised the snowline, drastically reducing the crucial mountain snow pack, the researchers told the American Geophysical Union in San Francisco. "We realized that huge areas of the snow pack in the Sierra went down to 15 percent of today's values," says Michael Dettinger, a research hydrologist at the Scripps Institution of Oceanography in La Jolla, California. That caught everyone's attention.The researchers also predict that by the middle of the century, melting snow will cause streams to reach their annual peak flow up to a month earlier. And with warm rains melting snow or drenching already saturated ground, the risk of extreme floods will rise dramatically. We have to believe in these very warm, very wet storms, says Andrew Wood, a water resources modeler at the University of Washington, Seattle."Since dams can't be filled until the risk of flooding is past, the models predictthey will trap just 70 to 85 percent as much run-off as they do now. This is a particular problem for California, where agriculture, industry, a burgeoning population and environmental needs already clash over limited water supplies. We are taking this extremely seriously," says Jonas Minton, deputy director of the California Department of Water Resources.And observations certainly back up the models. Minton points out that an increasing percentage of California's precipitation over recent decades is falling as rain rather than snow. And Iris Stewart, a climate researcher at the University of California, San Diego, has found that in the last 50 years, run-off peaks in the western US and Canada have been happening earlier and earlier. The cause seems to be a region-wide trend towards warmer winters and springs.Dettinger has little doubt that the models point to a real and immediate problem. "It's upon us," he says, "and it's not clear what the fix is."52、The primary purpose of this passage is to ______.(PASSAGE ONE)A. praise Levy for his contribution to the observation of cometsB. show that an amateur can do things as well as a professionalC. introduce David Levy as an astronomer and his professionD. demonstrate that strong interest can help a person succeed in his life53、All of the following are suggested in this passage as reasons for Levy's success EXCEPT that ______.(PASSAGE ONE)A. he had books and articles published on astronomyB. he worked on projects intended to introduce astronomyC. he was endowed with the gift of the discovery of cometsD. he was highly praised by his colleagues for his unselfishness54、David Hartsel most appreciates Levy's ______.(PASSAGE ONE)A. gifted ability of comet huntingB. way of expressing himselfC. curiosity to the sky and cometsD. spirit of devotion to astronomy55、What does the example of India illustrate?(PASSAGE TWO)A.

Failure to follow the above instructions may result in a loss of marks.Separating no science and arts educationSince 2009, with the issue of the China's Medium and Long Term Education Reform and Development, there ushered in the heated discussion of "the necessity and the feasibility to abolish science and art division in high school".It heralded 2015-2016's Gaokao Reform in many provinces to drop the previous rigorous division of science and art like Shanxi, Changsha, Tianjing, Fujian... etc.The main reasons are as follows:The NPC Standing Committee member Zhu Yongxin said in an interview with Southern Weekend, "the severe of science and art does conspicuous damage to students' intelligence and knowledge." He also said that the previous education strategy stifled the potential of students by restricting them too early in science or art and they should be given choices until maturity.The headmaster of Guangxi TVU He Zubing, "there is definitive categorization in knowledge like science and art but life has no such categorization."According to a poll done by Southern Weekend, there is a pervasive prejudice of art education. The students in science are endeared while those in art are often snuffed at in everyday society.It is early for students to receive art-science separate education; students should learn art or science separately in college but not high school.答案:PART ⅠDICTATION1、[听力原文]TouchingTactile communication is the use of touch in communication./ Touch may be viewed as the most extreme form of invasion of personal space./ Nonetheless, touch is essential to our growth and development./ An insufficient amount of touching can result in health disorders such as allergies, speech problems and problems with symbolic recognition./ Researches have found that untouched babies and small children grow increasingly ill./Touch is one of the most powerful ways we have of communicating with others./ The pleasure touch causes originates in infancy./ For most people, touching is positive and enjoyable./ People who are comfortable with touch tend to be satisfied with themselves, their lives and their childhoods./ They are self-confident, assertive, display a socially acceptable self-presentation, and active rather than passive ways of dealing with problems./In most cultures, touch is associated with positive attitudes./ It is one of the clearest indications that we like and accept others and they like and accept us.PART ⅡLISTENING COMPREHENSIONSECTION A TALK2、overtaken/surpassed[听力原文]Car SafetyWell, good afternoon. In today's session I will be sharing some of the findings of my project from last term. I had been interested and horrified by several newspaper reports on what people call "road rage". For example the famous incident of a man getting out of his car in a car park and hitting the driver of a van who had overtaken him earlier. So I decided to make this the focus of the project.For our research we depended mainly on talking to individuals, asking them questions rather than using written questionnaires. Well, we found 93% of respondents had had some kind of problem. A surprisingly large percentage—24% had their car damaged in some way, but the main type of incident was being shouted at—79% had experienced that. The police tended only to be informed when there was physical violence involved.So what strategies had people developed to ensure their own safety? We found that both sexes made the point that it's much safer to get keys out well in advance as you go towards your car. Men were very aware that muggers or whatever might be concealed behind the car. They also made the point that you should leave plenty of room when you park your car so you can make a quick getaway if you need to. Finally, locking doors at all times.Besides self-protection skills, when road rage does happen at the very moment, something needs to be done. Maryland, like many other states, is working on the problem by stepping up efforts to crack down on aggressive drivers. Hefty fines for dangerous drivers and speeders are on the front line against road rage. California is approaching the problem with technology. A new automated system being installed by the state automatically takes photographs of the license plates of vehicles that run red lights. It even captures accident scenes for police review. A key factor in reversing the process is an apology. A road rager can become upset because you accidentally cut in front of him or her, or for other reasons that were not intentional. Over 85% of road ragers said that they would drop the matter if the other "careless" driver simply apologized. Instead, road ragers claim, the "careless" driver seems to be unconcerned about what they just did and, therefore, needs to be taught a lesson. In a ear, only one method is effective in conveying an apology: A sign. We have found that it is very effective in warding off anger. In fact, many drivers actually smile when we raise a "SORRY" sign to them after we have accidentally done something wrong. We keep a "SORRY" sign in the map holder on the driver's door and the passenger's door. It could also be kept under the sun visor if it is fastened with a clip or rubber band so that it doesn't hit you in the face when the visor comes down.To sum up, I have described the phenomenon of road rage, explained the findings of the survey, and presented the strategies to ensure safety and self-protection skills. That's it for today.[解析] 细节题。
