    Do you want to live another 100 years or more? Some experts say that scientific advances will
    one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.
    “ I think we are knocking at the door of immortality (永生),” said Michael Zey, a Montclair State University business professor and author of two books on the future. “ I think by 2075 we will see it and that’s a conservative estimate.”
    At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology(纳米技术) make it likely that humans will live in the future beyond what has been possible in the past. “ There is a great push so that people can live from 120 to 180 years,” he said. “ Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.”
    However, many scientists who specialize in aging are doubtful about it and say the human body is just not designed to last about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.
    Scientists also differ on what kind of life the super aged might live. “ It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life?” said Leonard Poon, director of the University of Georgia Gerontology Center. “ At present people who could get to that point are not in good health at all.”
    67. By saying “ we are knocking at the door immortality”, Michael Zey means_____.
    A. they believe that there is no limit of living
    B. they are sure to find the truth about long living
    C. they have got some ideas about living forever
    D. they are able to make people live past the present life span
    68. Donald Louria’s attitude toward long living is that_____.
    A. people can live from 120 to 180
    B. it is still doubtful how long humans can live
    C. the human body is designed to last about 120 years
    D. it is possible for humans to live longer in the future
    69. The underlined “ it” (Para. 4) refers to_____.
    A. a great push
    B. the idea of living beyond the present life span
    C. the idea of living from 200 to 300
    D. the conservative estimate
    70. What would be the best title for this text?
    A. Living longer or not
    B. Science, technology and long living
    C. No limit for human life
    D. Healthy lifestyle and long living

    Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri(MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient.
    “To provide enough power, we need certain methods with high energy density(密度)”，said Jae Kwon, assistant professor of electrical and computer engineering at MU. “The radioisotope(放射性同位素) battery can provide power density that is much higher than chemical batteries.”
    Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro / nanoelectromechanical systems (M/NEMS). Although nuclear batteries can cause concerns, Kwon said they are safe.
    “People hear the word ‘nuclear’ and think of something very dangerous,” he said, “However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems.”
    His new idea is not only in the battery’s size, but also in its semiconductor(半导体). Kwon’s battery uses a liquid semiconductor rather than a solid semiconductor.
    “The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure(晶体结构) of the solid semiconductor,” Kwon said, “By using a liquid semiconductor, we believe we can minimize that problem.”
    Together with J. David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery. In the future, they hope to increase the battery’s power, shrink its size and try with various other materials. Kwon said that battery could be thinner than the thickness of human hair.
    1. Which of the following is true of Jae Kwon?
    A. He teaches chemistry at MU. 
    B. He developed a chemical battery.
    C. He is working on a nuclear energy source.
    D. He made a breakthrough in computer engineering.
    2. Jae Kwon gave examples in Paragraph 4_________.
    A. to show chemical batteries are widely applied.
    B. to introduce nuclear batteries can be safely used.
    C. to describe a nuclear-powered system.
    D. to introduce various energy sources.
    3. Liquid semiconductor is used to _________.
    A. get rid of the radioactive waste  
    B. test the power of nuclear batteries.
    C. decrease the size of nuclear batteries
    D. reduce the damage to lattice structure.
    4. According to Jae Kwon, his nuclear battery _______.
    A. uses a solid semiconductor       
    B. will soon replace the present ones.
    C. could be extremely thin          
    D. has passed the final test.
    5. The text is most probably a ________.
    A. science news report        B. book review   
    C. newspaper ad              D. science fiction story

    Ocean Acidification: 'Evil Twin' Threatens World's Oceans
    The rise in human emissions of carbon dioxide is driving dangerous changes in the chemistry and ecosystems of the world's oceans, international marine（海洋的）scientists have warned. "Ocean conditions are already more extreme than those experienced by marine organisms and ecosystems for millions of years," says the latest issue of the journal Trends in Ecology and Evolution. "This emphasizes the urgent need to adopt policies that markedly reduce CO2 emissions."
    Ocean acidification, which the researchers call the 'evil twin of global warming', is caused when the CO2 emitted by human activity, mainly burning fossil fuels, dissolves into the oceans. It is happening independently of, but in combination with, global warming. Evidence gathered by scientists over the last few years suggests that ocean acidification could represent an equal -- or perhaps even greater threat -- to the biology of our planet than global warming. More than 30% of the CO2 released from burning fossil fuels, cement production, deforestation and other human activities goes straight into the oceans, turning them gradually more acidic.
    "The resulting acidification will impact many forms of sea life, especially organisms whose shells or skeletons are made from calcium carbonate（碳化钙）, like corals and shellfish. It may interfere with the reproduction of plankton species which are a vital part of the food web on which fish and all other sea life depend," he adds.
    The scientists say there is now persuasive evidence that mass extinctions in past Earth history, like the "Great Dying" of 251 million years ago and another wipeout 55 million years ago, were accompanied by ocean acidification, which may have delivered the deathblow to many species that were unable to cope with it. "These past periods can serve as great lessons of what we can expect in the future, if we continue to push the acidity the ocean even further" said lead author, Dr. Carles Pelejero, from ICREA and the Marine Science Institute of CSIC in Barcelona, Spain. "Given the impacts we see in the fossil record, there is no question about the need to immediately reduce the rate at which we are emitting carbon dioxide in the atmosphere," he said further.
    "Today, the surface waters of the oceans have already acidified by an average of 0.1 pH units from pre-industrial levels, and we are seeing signs of its impact even in the deep oceans," said co-author Dr. Eva Calvo, from the Marine Science Institute of CSIC in Spain. "Future acidification depends on how much CO2 humans emit from here on -- but by the year 2100 various projections indicate that the oceans will have acidified by a further 0.3 to 0.4 pH units, which is more than many organisms like corals can stand," Prof. Hoegh-Guldberg says.
    "This will create conditions not seen on Earth for at least 40 million years."
    "These changes are taking place at rates as much as 100 times faster than they ever have over the last tens of millions of years" Prof. Hoegh-Guldberg says. Besides directly impacting on the fishing industry and its contribution to the human food supply at a time when global food demand is doubling, a major die-off in the oceans would affect birds and many land species and change the biology of Earth as a whole profoundly, Prof. Hoegh-Guldberg adds.
    67. What is the biggest cause of the ocean acidification according to the report?
    A. the increase of carbon dioxide emission by human beings
    B. The worsening of global warming
    C. The disappearance of the world’s forests
    D. The decrease of marine life
    68. In what way according to the report does ocean acidification affect the majority of marine life?
    A. It affects their reproduction          B. It destroys their food chain
    C. It affects the growth of their young    D. destroys their habitats
    69. Which of the following statements is NOT true about ocean acidification?
    A. Ocean acidification has made ocean conditions most extreme in millions of years.
    B. Ocean acidification may do more damage than global warming to human and plant life in the long run.
    C. Ocean acidification is suspected of having caused mass extinctions of life in past Earth history.
    D. The effects of ocean acidification are not now but will be felt in the foreseeable future.
    70. From the report we can clearly feel that the situation with ocean acidification __________.
    A. is quite optimistic                B. remains well under control
    C. looks more than urgent            D. is already out of control

    If you look up the word “create” in the dictionary, you will find it means “to brig into being to cause to exist something each of us does daily.”
    We are creative whenever we look at or think about something in a new way. First this involves an awareness of our surroundings. It means using all of our sonses to become aware of our world. This may be as simple as being aware of color and texture（质地）, as well as taste, when we plan a meal. Above all, it is the ability to notice things that others might miss.
    A second part of creativity is an ability to see relationships among things. If we believe the expression, “There is nothing new under the sun, the creativity is remaking or recombining（重组） the old in new ways.” For example, we might do this by finding a more effective way to study or a better way to arrange our furniture, or we might make a new combination of camera lenses and filters to create an unusual photograph.
    A third part of creativity is the courage and drive to make use of our new ideas, to apply them to achieve some new results. To think up a new concept is one thing; to put the idea to work is another.
    These three parts of creativity are involved in all the great works of genius, but they are also involved in many of our day-to-day activities.
    64．Which of the following activities is NOT a creative one according to the passage?
    A．To prepare a meal.
    B．To arrange the furniture in a peculiar way.
    C．To buy some books from a bookstore.
    D．To “write” a letter with the computer.
    65．“There is nothing new under the sun.” (Par.3) really implies that ____.
    A．a new thing can only be created at the basis of earlier things
    B．a new thing is only a tale
    C．we can seldom create new things
    D．we can scarcely see really new things in the world
    66．What does the author think about the relationship between a new thought and its being put into
    practice?
    A．It´s more difficult to create a new thought than to apply it in practice.
    B．To find a new thought will definitely lead to the production of a new thing.
    C．A man with an excellent ability of practice can easily become an inventor.
    D．One may come up with a new thought, but can not put it into practice.
    67．The best title for this passage is ____.
    A．How to Cultivate One´s Creativity      
    B．What is Creativity
    C．The Importance of Creativity            
    D．Creativity, a Not Farway Thing

    Millions of people will be able to track each and every move by friends and family through their mobile phones，thanks to a new feature launched by Google yesterday．
    The new system named “Latitude” uses a map to show exactly where a loved one is at any time, sometimes discovering their location to a few meters．Worried parents will be able to check up on where their children have got to after school, friends can meet for a quick drink if they see they are nearby and wives will be able to see if their husbands really are working late at the office．
    The feature was made available immediately on millions of mobile phones that can access the web，such as the Black Berry．Within weeks Google hopes to launch a new one that will also work on computers as well．
    “Once you've shared your location，you can hide it from all of your friends at once，or you can turn off Google Latitude completely at any time．” said a Google spokesman．“You can adjust your privacy settings in Latitude so that you share as much or as little about your location as you want，with whom you want．”
    Google said that the company had tested the product with thousands of people to make sure that it was safe for the customers，but experts were not so sure．Simon Davies，director of Privacy International，said Latitude would open up a “privacy minefield（危险地带）”．
    “It's about the little white lies．You might be avoiding going to work, and now your boss might be able to see that you're at Twickenham instead of at home．”said Ian Angell, an information expert at the London School of Economics．“You've already got mobile phone technology where husbands and wives track each other in secret．Now Google is so widely used that it will only worsen the situation．”

    In nineteen ninety-nine, twelve percent of public elementary schools in the United States required students to wear uniforms. Just three years later, estimates were almost double that.
    A study of six big-city Ohio public schools showed students who were required to wear uniforms had improved graduation, behavior and attendance rates. Academic performance was unchanged.
    Some middle and high schools in Texas have also joined the movement. Yet studies find mixed results from requiring uniforms. And some schools have turned away from such policies.
    Supporters believe dressing the same creates a better learning environment and safer schools. The school district in Long Beach, California, was the first in the country to require uniforms in all elementary and middle schools. The example helped build national interest in uniforms as a way to deal with school violence and improve learning.
    Findings in Long Beach suggested that the policy resulted in fewer behavior problems and better attendance. But researcher Viktoria Stamison, who has looked at those findings, says they were based only on opinions about the effects of uniforms.
    She says other steps taken at the same time to improve schools in Long Beach and statewide could have influenced the findings. The district increased punishments for misbehavior. And California passed a law to reduce class sizes.
    In Florida, for example, researcher Sharon Pate found that uniforms seemed to improve behavior and reduce violence. In Texas, Eloise Hughes found fewer discipline problems among students required to wear uniforms, but no effect on attendance.
    Sociologist David Brunsma has studied school uniform policies since nineteen ninety-eight. He collected the reports in the book. In his own study, he found that reading and mathematics performance dropped after a school in rural Pennsylvania required uniforms.
    Political and community pressures may persuade schools to go to uniforms to improve learning. But David Brunsma and others believe there is not enough evidence of a direct relationship. In fact, he says requiring uniforms may even increase discipline problems.
    52. What’s the main idea of this passage?
    A. More and more students are required to wear uniforms in the US.
    B. Wearing uniforms contributes to good academic performance.
    C. Researchers in the US argue for school uniform policies.
    D. Evidence for school uniform policies in the US is seen as weak.
    53. Which was/were the first in the US to require uniforms in all elementary and middle schools?
    A. Six big-city Ohio public schools.
    B. The school district in Long Beach, California.
    C. Some middle and high schools in Texas.
    D. Some elementary and middle schools in Florida.
    54. Which of the following researchers are NOT supporters of school uniform policies?
    A. Viktoria Stamison and Sharon Pate.  
    B. Sharon Pate and David Brunsma.
    C. Eloise Hughes and Sharon Pate.  
    D. Viktoria Stamison and David Brunsma.
    55. The underlined word “misbehavior” in the sixth paragraph probably means ______.
    A. serious crime            B. bad performance
    C. absence for class       D. action against wearing uniforms
    56. We can infer from the passage that ______.
    A. more work is needed to get better information about uniform’s effect
    B. the number of schools requiring uniforms in the US will decline sharply
    C. wearing uniforms has little to do with behavior and learning
    D. politicians and communities won’t vote for uniform policies

    Winter is dangerous for drivers because it’s so difficult to know what is going to happen and accidents take place easily. Bad weather can be waiting to meet you. Ice might be hiding under the snow, waiting to send you off the road. The car coming towards you might suddenly move across the road. Here are two rules for driving safely on icy roads:
    Rule Number One is to drive smoothly. Irregular movements can make a car very difficult to manage. So each time you either turn the wheel, touch the brake or increase your speed, you must be as gentle and slow as possible. Just imagine you are driving with a full cup of hot coffee on the seat next to you. You should drive carefully enough in order that you wouldn’t get the coffee out of the cup.
    Rule Number Two is to pay attention to what might happen. The more ice there is, the farther you have to look down the road. Test how long it takes to stop by gently braking. Remember that you may be driving more quickly than you think. Generally speaking, allow double your normal stopping distance when the road is wet, three times this distance on snow, and even more on ice. Try to stay in control of your car at all times, or you will get into trouble.
    49. Driving in winter is dangerous because _________.
    A. drivers usually have too much coffee      B. people drive three times faster than usual
    C. unexpected things may often happen              D. people drive more gently and slowly
    50.Rule Number One mainly tells us _________.
    A. to drive fast on snowy roads                   B. to increase the driving speed
    C. to manage your car irregularly                D. to drive smoothly on icy roads
    51.Which of the following can be the best title of the passage?
    A. Winter Driving  B. Careless Driving   C. Traffic Accidents         D. Bad Weather
    52.Where do you think you might read such a passage?
    A. In dictionaries.   B. In cookbooks.     C. In advertisements.  D. In magazines.

    第三部分阅读理解（共20题，每小题2分，满分40分）
    Recently, tests have proved that Beethoven died from lead poisoning. Bill Walsh directed the Beethoven Research Project. Mr. Walsh and his team examined pieces of bone belonging to Beethoven. They found a large amount of lead in the bone pieces. They said the lead levels were equal to those found in pieces of his hair in earlier studies of other scientists.
    Genetic tests proved the bone pieces and his hair came from Beethoven. The research also examined bone fragments from someone else who lived during the same period. Both were from the top of the skull. The fragments from Beethoven had more lead than those from other person. Their study didn’t find measurable levels of cadmium(镉) or mercury(汞), which scientists used to consider were the causes of his health problems.
    Beethoven was sick for much of his life. He experienced strong stomach pains, a sign of lead poisoning, and a change of personality when he was around 20. he also got angry easily, and suffered from depression and hearing loss. His health problems became worse as he grew older.
    Walsh said the lead levels found in his skull suggested that the metal might have been present in his body for many years. He said although there had been recognized cases of deafness caused by lead poisoning, there was no strong evidence to suggest that lead poisoning was the cause of his deafness.
    Beethoven visited many doctors to find a cure for his health problems, in a letter he wrote to a friend, he urged researchers to examine his body after he died so that other people would not have to suffer as he did.
    61. If too much lead is in a person’s body, he will______.
    A. suffer hearing loss             B. get angry easily 
    C. suffer serious stomach pains     D. lose most of his hair
    62. From the passage we can learn that_______.
    A. this is the first research into the cause of Beethoven’s death
    B. any amount of lead will do great harm to people’s health
    C. more lead was found in Beethoven’s bones than in his hair
    D. scientists used to think that his death was caused by other metals instead of lead
    63. In which section of the newspaper might you read this report?
    A. Health.   B. Technology.   C. Entertainment.   D. Culture.
    64. What is the best title of the passage?
    A. A surprising discovery about Beethoven   B. Beethoven died from lead poisoning
    C. Lead--- a killer metal for human beings    D. New examination of Beethoven’ body
