    The computer is fast, and never makes a mistake, while people are too slow, and full of mistakes sometimes. That’s what people often say when they talk about computers. For over a quarter of a century, scientists have been making better and better computers. Now a computer can do a lot of everyday jobs wonderfully. It is widely used in factories, hospitals, post office and airports. A computer can report, decide and control in almost every field. Many computer scientists are now thinking of making the computer “think” like a man. With the help of a person, a computer can draw pictures, write music, talk with people, play chess, recognize voice, translate languages and so on. Perhaps computer will one day really think and feel. Do you think the people will be afraid when they find that the computer too clever to listen to and serve the people?

    The damming of river systems in the northwestern United States has had damaging effects on salmon(鲑鱼). In the spring young salmon, called smolts, drift into rivers from smaller streams. They swim with the current downstream heading for the Pacific Ocean. Before the large-scale constructions of dams(水坝), the young salmon used the strong flow from melting snows to get to the sea in between six and twenty days. It is necessary to do this because during these days the smolts’ bodies undergo the physiological changes for adaptation to salt water.
    Unfortunately, the current has become very slow due to the construction of numerous dams. Companies operating the dams also intentionally slow the current. They store the water from the melting snow until the winter, when more electric power is needed. The net result is that many of the young fish do not survive the now sixty-day trip to the sea. Consequently, there are fewer adult salmon to migrate(回游) back up the rivers for breeding. When the time comes for the salmon to return, they again face the problem of dams. As fewer adult salmon are able to get back to their cool upstream water, they fail to produce a sufficiently new generation of salmon.  This cycle could eventually lead to the extinction of the fish.
    Attempts are being made to transport the young salmon down river by boats. However, many scientists think that this artificial method of getting the fish to the sea kills more than it saves. Another suggestion, recently proposed by environmentalists, is to increase the rate of water flow. This would be a partial（部分的） solution to the declining salmon numbers. One method of doing this would call for releasing water from upstream dam. This would speed up the downstream movement of the smolts.
    Another method would be to reduce the water level in the dams for a period in the spring when the smolts are migrating downstream. This would also increase the flow rate temporarily without requiring large amounts of water and, thus, enable the young salmon to move downstream faster. Unfortunately, both of these proposals have met with criticism from the power companies, which strongly suggests the uncertain fate of the salmon in the region.
    76. What’s the main topic of the passage?
    A. The failure of adult salmon to reproduce.
    B. The importance of smolts returning upstream.
    C. The need for smolts to reach salt water quickly.
    D. The harm caused to salmon by river damming.
    77. The passage discusses all of the following methods of dealing with salmon issue EXCEPT _____.
    A. carrying the fish in boats
    B. allowing water to be released from upstream dams
    C. dropping water levels in dams
    D. breeding salmon
    78. In paragraph 3, what does the author mean by the statement that many scientists think that this artificial method of getting the fish to the sea kills more than it saves?
    A. Saving fish is artificial.
    B. More fish die when transported than would die otherwise
    C. Artificial methods of transportation give salmon the chance to get adapted to salt water.
    D. The sea kills more fish than are saved by transportation.
    79. Which of the following statements would the author most probably agree with?
    A. The salmon problem is likely to continue.
    B. A solution to the salmon problem will be found in the near future.
    C. Salmon will be extinct very quickly. 
    D. The government should step in and provide a way out.

    Climate has been a major driver of armed conflict in Africa, research shows—and future warming is likely to increase the number of deaths from war. US researchers found that across the continent, conflict was about 50% more likely in unusually warm years.
    Writing in Proceedings of the National Academy of Sciences (PNAS), they suggest conflict arises when the food supply is not enough in warm conditions. Climatic factors have been mentioned as a reason for several recent conflicts. One is the fighting in Darfur in Sudan that has killed 200,000 people and forced two million more from their homes. Previous research has shown an association between lack of rain and conflict, but this is thought to be the first clear evidence of a temperature link.
    The researchers used databases of temperatures across sub-Saharan Africa for the period between 1981 and 2002, and looked for connections between above average warmth and civil conflict in the same country that left at least 1,000 people dead. "Studies show that crop output in the region is really sensitive to small shifts in temperature, even of half a degree or so," research leader Marshall Burke, from the University of California at Berkeley, told BBC News.
    "Our findings provide strong motivation to increase investments in African adaptation to climate change by such steps as developing crop varieties less sensitive to extreme heat and promoting insurance plans to help protect farmers from negative effects of the hotter climate," said Dr Burke. "If the argument is that the trend towards rising temperatures will increase conflict, then we need to do something around climate change, but more fundamentally we need to resolve the conflicts in the first place."
    If the sub-Saharan climate continues to warm and little is done to help its countries better adapt to high temperatures, the human costs are likely to be unimaginable. If temperatures rise across the continent as computer models project, future conflicts are likely to become more common, researchers suggest. Their study shows an increase of about 50% over the next 20 years.
    When projections of social trends such as population increase and economic development were included in their model of a future Africa, temperature rise still emerged as a likely major cause of increasing armed conflict. At next month's UN climate summit (峰会) in Copenhagen, governments are due to debate how much money to put into helping African countries prepare for and adapt to negative effects of climate change.
    57．According to the passage, which of the following is one of the reasons for the fighting in Darfur in Sudan?
    A．Shortage of drinking water.                         B．Racial discrimination.
    C．Rising temperature.                                     D．Demand for planting land.
    58．What can we know from the research done by the US researchers?
    A．There is no close relation between rainfall and conflict.
    B．Temperature greatly affects crop production in sub-Saharan Africa.
    C．Temperature will rise by about 50% in Africa over the next two decades.
    D．With world cooperation, conflicts in Africa will be reduced by half 20 years later.
    59．What can be inferred from the passage?
    A．Something must be done to help sub-Saharan countries with better adaptation to climate change to avoid disaster.
    B．Conflicts in sub-Saharan countries are sure to be on the rise in future.
    C．Temperature in sub-Saharan countries will rise at a faster speed.
    D．High temperatures will make sub-Saharan countries unfit to live in.
    60．What's the best title for this passage?
    A．World cooperation against African conflict
    B．Africa's sufferings from climate change
    C．Food shortages lead to African conflict
    D．Climate drives African conflict

    A team of researchers in California has developed a way to predict what kinds of objects people are looking at by scanning what’s happening in their brains.
    When you look at something, your eyes send a signal about that object to your brain. Different regions of the brain process the information your eyes send. Cells in your brain called neurons(神经元) are responsible for this processing.
    　　The fMRI (functional Magnetic Resonance Imaging功能性磁共振造影) brain scans could generally match electrical activity in the brain to the basic shape of a picture that someone was looking at.
    　　Like cells anywhere else in your body, active neurons use oxygen. Blood brings oxygen to the neurons, and the more active a neuron is, the more oxygen it will consume. The more active a region of the brain, the more active its neurons, and in turn, the more blood will travel to that region. And by using fMRI, scientists can visualize which parts of the brain receive more oxygen- rich blood--and therefore, which parts are working to process information.
    　　An fMRI machine is a device that scans the brain and measures changes in blood flow to the brain. The technology shows researchers how brain activity changes when a person thinks, looks at something, or carries out an activity like speaking or reading. By highlighting the areas of the brain at work when a person looks at different images, fMRI may help scientists determine specific patterns of brain activity associated with different kinds of images.
    　　The California researchers tested brain activity by having two volunteers view hundreds of pictures of everyday objects, like people, animals, and fruits. The scientists used an fMRI machine to record the volunteers' brain activity with each photograph they looked at. Different objects caused different regions of the volunteers' brains to light up on the scan, indicating activity. The scientists used this information to build a model to predict how the brain might respond to any image the eyes see.
    In a second test, the scientists asked the volunteers to look at 120 new pictures. Like before, their brains were scanned every time they looked at a new image. This time, the scientists used their model to match the fMRI scans to the image. For example, if a scan in the second test showed the same pattern of brain activity that was strongly, related to pictures of apples in the first test, their model would have predicted the volunteers were looking at apples.
    　　 51. What is responsible for processing the information sent by your eyes?
    　　A A small region of the brain.
    　　B The central part of the brain.
    　　C Neurons in the brain.
    　　D Oxygen-rich blood.
    　　52. Which of the following statements is NOT meant by the writer?
    　　A Cells in your brain are called neurons.
    　　B The more oxygen a neuron consumes, the more blood it needs.
    　　C fMRI helps scientists to discover which parts of the brain process information.
    　　D fMRI helps scientists to discover how the brain develops intelligently.
    53. "Highlighting the areas of the brain at work" means
    　　A "marking the parts of the brain that are processing information"
    　　B "giving light to the parts of the brain that are processing information"
    　　C "putting the parts of the brain to work"
    　　D "stopping the parts of the brain from working"
    　　54. What did the researchers experiment on?
    　　A Animals, objects, and fruits.
    　　B Two volunteers.
    　　C fMRI machines.
    　　D Thousands of pictures.
    55.What is the best title for the passage?
    A Mind-reading Machine
    B A Technological Dream
    C Device that can Help You Calculate

    （C）
    Astronaut Jim Voss has enjoyed many memorable moments in his career，including three space flights and one space walk. But he recalls with special fondness a decidedly earthbound（为地球引力所束缚的）experience in the summer of 1980 when he participated in the NASA ASEE Summer Faculty Fellowship Program. Voss， then a science teacher at West Poin，was assigned to the Marshall Space Flight Center's propulsion（推进） lab in Alabama to analyze why a hydraulic fuel pump seal （液压燃料泵的密封圈）on the space shuttle（航天飞机） was working so well when previous seals had failed. It was a seemingly tiny problem among the vast complexities of running the space program. Yet it was important to NASA because any crack in the seal could have led to destructive results for the astronauts who relied on them.
    “I worked a bit with NASA engineers，” says Voss， “but I did it mostly by an analysis. I used a handheld calculator， not a computer， to do a thermodynamic（热力学的） analysis.” At the end of the summer，he，like the other NASA ASEE fellows working at Marshall，summarized his findings in a formal presentation and detailed paper. It was a valuable moment for Voss because the ASEE program gave him added understanding of  NASA，deepened his desire to fly in space，and intensified his application for astronaut status.
    　　It was not an easy process. Voss was actually passed over when he first applied for the astronaut program in 1978. Over the next nine years he reapplied repeatedly，and was finally accepted in 1987. Since then he has participated in three space missions. The 50 year old Army officer，who lives in Houston，is now in training for a four-month mission as a crew member on the International Space Station starting in July 2000.
    　Voss says the ASEE program is wonderful for all involved. “It brings in people from the academic world and gives NASA a special property for a particular period of time. It brings some fresh eyes and fresh ideas to NASA，and establishes a link with our colleges and universities，” Voss explains. “There's an exchange of information and an exchange of perspectives that is very important.”
    For the academic side，Voss says，the ASEE program also “brings institutions of higher learning more insight into new technology. We give them an opportunity to work on real world problems and take it back to the classroom.”
    66. Why was the hydraulic fuel pump seal important for the space shuttle？
    A） Because previous seals all failed.
    B） Because it was very complex in running the space program.
    C） Because great care has to be taken of the hydraulic fuel pump sealing.
    D） Because any crack in the seals would cause disastrous results for the astronauts.
    67.The great significance of Voss's findings lies in_________ .
    A） strengthening his determination to join in space flights
    B） furthering his understanding of NASA
    C） consolidating his astronaut status in NASA programs
    D） Both A and B
    68. How many flights will Voss have finished if his four-month mission starting in July 2000 ends up successfully？
    A） Three  B） Two   C） Four     D） Five
    69. Which of the following is NOT TRUE according to what Voss said on the ASEE program？
    A） Fresh members from the academic world participate in the program.
    B） The program brings new outlooks to NASA space programs.
    C） It is important for the space scientists to exchange information and perspectives.
    D） American colleges and universities are a special property of NASA.
    70. What does Voss want to stress in the last paragraph？
    A） The technological significance of the program.
    B） The educational significance of the program.
    C） The philosophical significance of the program.
    D） The historical significance of the program.

      Educating girls quite possibly produces a higher rate of return than any other investment(投
    资)available in the developing world．Women’s education may be an unusual field for experts On economy(经济)，but improving women’s contribution to development is actually as much all economic as a social business．And economics provides an explanation for why so many girls are
    deprived of an education．
    Parents in low-income countries fail to invest in their daughters because they do not expect them to make all economic contribution to the family：girls grow up only to marry into somebody
    else’s family and bear children．Girls are thus seen as less valuable than boys and are kept at home to do housework while their brothers are sent to school．Ignoring women’s education is therefore in a bad circle．
    An educated mother, on the other hand, has greater earning abilities outside the home and faces an entirely different set of choices．She is likely to have fewer but healthier children and can insist on the development of all her children, making sure that her daughters are given a fair chance．The education of her daughters then makes it much more likely that the next generation of girls，as well as of boys，will be educated and healthy．The bad circle is thus changed into a good
    circle．
    Educating women has great social benefits and great economic advantages as well．Most obviously, there is the direct effect of education on the wages of female workers．Wages rise by 10 to 20 per cent for each additional year of schooling．Such big returns are impressive by the standard of other available investments，but they are just the beginning．Educating women also has a significant effect on health practices, including family planning．

           File-sharing occurs whenever one individual sends a file to another. The only way to even try to limit this process is to monitor all communication between ordinary people. Despite the crackdown on Napster, Kazaa and other peer-to-peer(对等网络) services over the past decade, the volume of file-sharing has grown exponentially. Even if the authorities closed down all other possibilities, people could still send copyrighted files as attachments to e-mails or through private networks. If people start doing that, should we give the government the right to monitor all mail and all encrypted(加密) networks? Whenever there are ways of communicating in private, they will be used to share copyrighted material. If you want to stop people doing this, you must remove the right to communicate in private. There is no other option. Society has to make a choice.
    The world is at a crossroads. The internet and new information technologies are so powerful that no matter what we do, society will change. But the direction has not been decided.
    The internet it still in its infancy, but already we see fantastic things appearing as if by magic. Take Linux, the free computer operating system, or Wikipedia, the free encyclopedia. But where technology opens up new possibilities, our intellectual property laws do their best to restrict them. Linux is held back by patents, the rest of the examples by copyright. The public increasingly recognizes the need for reform.
    Our manifesto(声明) is to reform copyright laws and gradually abolish(废除) the patent system. We oppose mass surveillance (监视)and censorship(审查制度) on the net, as in the rest of society. We intend to devote all our time and energy to protecting the basal civil liberties on the net and elsewhere.
    Political decisions taken over the next five years are likely to set the course we take into the information society, and will affect the lives of millions for many years into the future. The information revolution is happening here and now. It is up to us to decide what future we want.
    41. Which of the following statements is NOT true according to the passage?
    A. Over the past decade, the volume of file-sharing has increased doubly.
    B. Over the past decade, other peer-to-peer(对等网络) services have been beaten down.
    C. Copyright laws should be reformed.
    D. File-sharing occurs unless a file is sent on the Internet.
    42. In the opinion of the writer, the government ________.
    A. has to make a choice
    B. should stop people sharing the copyrighted files
    C. shouldn't stop people sharing the copyrighted files
    D. should monitor all the mail and all encrypted (加密) networks
    43. The author's main purpose in writing the passage is____________.
    A. to have the basal citizen's freedom on the net and elsewhere
    B. to establish the patent system
    C. to abolish copyright laws
    D. to reform computer operating system
    44. The underlined word “restrict” in Paragraph 3 most probably means__________.
    A. remove           B. limit               C. close                D. reform
    45. We can infer from the passage_______________.
    A. A new information revolution will be coming.
    B. People won't share copyrighted material on the net
    C. People can share the free encyclopedia
    D. The future of the Internet will rely on the government
