    D
    Are some people born clever, and others born stupid? Or is intelligence developed by our environment and experience? Strangely enough, the answer to these questions is yes. To some extent, person’s intelligence is fixed at birth, whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.
    It is easy to show that intelligence is to some extent something we are born with. The closer the blood relationship between two people, the closer they are likely to be in intelligence. Thus if we take two unrelated people at random(随意地) from the population, it is likely that their degree of intelligence will be completely different. If, on the other hand, we take two identical twins they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth.
    Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is  boring. We should soon find differences in intelligence developing, and this indicates that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all are likely to have similar degree of intelligence.
    68. The writer is in favor of the view that man’s intelligence is given to him
    A. at birth                          B. through education
    C. both at birth and through education    D. neither at birth nor through education
    69. If a child is born with low intelligence, he is unlikely to      
    A. become a genius so long as he or she works hard enough
    B. still become a genius if he should be given special education
    C. go beyond his intelligence limits even in rich surroundings
    D. never reaches his intelligence limits in his life
    70. The example of the twins going to a university and to a factory separately shows
    A. the importance of their intelligence      
    B. the role of environment on intelligence
    C. the importance of their positions        
    D. the part that birth plays
    71. What can be the best title for the text?
    A. Surroundings                           B. Intelligence
    C. Dependence on Environment              D. Effect of Education

    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

      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．

    B
    People all over the world today are beginning to hear and learn more and more about the problem of pollution. Pollution is caused either by man's release of completely new and often artificial substances into the environment, or by releasing greatly increased amounts of a natural substance , such as oil tankers into the sea．
    The whole industrial process which makes many of the goods and machines we need and use in our daily lives, is bound to create a number of waste products which upset the environmental balance, or the ecological balance as it is also known. Many of these waste products can be prevented or disposed of sensibly, but clearly while more and more new and complex goods are produce there will be new, dangerous wastes to be disposed of, for example, the waste products from nuclear power stations. Many people, therefore, see pollution as only part of a larger and more complex problem, that is, the whole process of industrial production and consumption of goods. Others again see the problem mainly in connection with agriculture, where new methods are helping farmers grow more and more on their land to feed our ever-increasing populations. However, the land itself is gradually becoming worn out as it is being used in some cases, too heavily, and artificial fertilizer cannot restore the balance.
    Whatever its underlying reasons, there is no doubt that much of the pollution caused could be controlled if only companies, individuals and governments would make more efforts. In the home there is an obvious need to control litter and waste. Food comes wrapped up three or four times in packages that all have to be disposed of; drinks are increasingly sold in bottles or tins which cannot be reused． This not only causes a litter problem, but also is a great waste of resources, in term of glass, metals and paper. Advertising has helped this process by persuading many of us not only to buy things we neither want nor need, but also to throw away much of what we do buy. Pollution and waste combine to be a problem everyone can help to solve by cutting out unnecessary buying ,excess consumption and careless disposal of the products we use in our daily lives.
    45．The underlined phrase “disposed of ”in the second paragraph means_______.
    A． dealt with               B． exposed 
    C． disapproved of           D． collected
    46． In the writer’s view ,the more new goods, _______.
    A． the less pollution             
    B． the harder pollution can be prevented
    C． the more pollution there will be
    D． the more easily pollution can be controlled
    47．What can we learn from the last paragraph?
    A． We can do much to reduce pollution.
    B． The government is trying hard to stop pollution.
    C． Individuals know how to get rid of the habit of littering everywhere.
    D． We can’t stop buying unnecessary things.
    48． People can help solve the problem of pollution by _______.
    A． urging their governments to control litter and waste
    B． making anti-pollution advertisements
    C． cutting down the use of oil and other oil products
    D． reducing unnecessary buying, over-consumption and careless disposal of wastes

           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

    B
    As a result of pollution, Lake Erie, on the borders of the USA and Canada, is now without any living things.
    Pollution in water is not simply a matter of “poisons” killing large numbers of fish overnight, Very often the effects of pollution are not noticed for many months or years because the first organisms（生物体）to be affected are either plants or plankton(浮游生物). But these organisms are the food of fish and birds and other creatures. When this food disappears, the fish and birds die too. In this way a whole food chain can be wiped out, and it’s not until dead fish and water birds are seen at the river’s edge or on the seashore that people realize what is happening.
    　　Where do the substances which pollute the water come from? There are two main sources of sewage（下水道污物）and industrial waste. As more detergent（洗涤剂）is used in the home, so more of it is finally put into our rivers, lakes and seas. Detergents harm water birds, dissolving the natural substances which keep their feathers water-proof (防水). Sewage itself, if not properly treated, makes the water dirty and prevents all forms of life in rivers and the sea from receiving the oxygen they need. Industrial waste is even more harmful as there are many highly poisonous things in it, such as copper and lead.
    　　So, if we want to stop this pollution, the answer is simple: sewage and industrial waste must be made clear before flowing into the water. It may already be too late to save some rivers and lakes, but others can still be saved if the correct action is taken at once.
    70. Pollution of water is noticed________.
    　　A. when the first organisms are affected　     
    B. when a good many fish and birds die
    　　C. when poisonous things are poured into water　
    D. as soon as the balance of nature is destroyed
    71.The living things die because there is no ________in the lake or river.
    　　A. water　　　　　            B. fish           　 C. poison　　　　　  D. oxygen
    72. Which of the following is harmful according to the passage?
    　　A. Organisms              　B. Plants and plankton in the water
    　　C. Waste water from cleaning    D. Industrial waste made clear before flowing into the water
    73. The way to stop water pollution is to________.
    　　A. realize the serious situation clearly
    　　B. put oxygen into the river
    　　C. make the waste material harmless before flowing into the water
    　　D. make special room in the sea for our rubbish

    D
    Film cameras and digital cameras work in a similar way.
    Film cameras
    After all, a film camera is basically a light – proof (不透光的) box. It has a lens (镜头) system to focus light onto the film at the back of the camera.
    Let’s suppose that we are outside on a beautiful summer day trying to take a picture of the family dog. We are using a film camera. We finally get the dog to lie still. You point the camera at him. What happens? Light goes into the camera lens and hits the shutter. In other words, nothing happens yet. Now let’s say that the dog looks really cute and you decide to snap a picture. What happens? When you press the button, the shutter open for a very short period of time. A small amount of light passes through and hits the film at the back of the camera. This creates an upside-down and reversed (反向的)image on the film.
    When you finish the roll of the film, you can take it to the photo shop to develop it and you will have a great picture of your dog!
    Cameras come with different lens lengths. Why does it matter? Many small cameras have shorter focal lengths, which means that there is a small distance between the lens and the place where the light focuses at the back of the camera. This gives you a large view of the area you are taking a picture of. Lenses with a long focal length show a smaller area but allow you to focus on distant objects and make them bigger. They are often called telephoto lenses. A good example of a long focus lens is one that is used by sports photographers to get photos of football players as if they were standing right beside them.
    Digital cameras
    In digital cameras, the light falls not on film but onto a sensor (传感器)called a CCD (Charge Coupled Device). This digitally converts(转变) light and colour into a digital information or pixels (象素). The CCD is the heart of any digital camera and usually the most expensive part ---- depending on how good it is.
    67．Which of the following statements is TRUE?
    A．Both digital and film cameras focus light onto the film.
    B．All cameras have a sensor.
    C．Digital cameras and film cameras have something in common. .
    D．Small cameras usually have longer focal lengths.
    68．In the “Film cameras” part, you fail to take the picture of the dog because _____.
    A．light goes into the camera lens and hits the shutter
    B．you haven’t aimed the camera at the dog
    C．the image of the dog is not created
    D．the sensor fails to convert light and colour into a digital information
    69．The main reason that sports photographers can get clear and big photos of players is that _ ___.
    A．they use digital cameras  B．the lens of their cameras is excellent
    C．their focus lenses are short      D．their focus lenses are long
    70．Generally speaking, a digital camera’s price is ____.
    A．closely related to the quality of the CCD
    B．irrelevant to the quality of the CCD
    C．closely related to the lens
    D．irrelevant to the lens
