    D
    The future of agriculture must achieve several goals at the same time.
    First, it now appears that we will have to double world food production in the next 40 years due to population growth, increasing meat consumption and pressure from biofuels (生物燃料). We will also have to reduce the environmental impacts from our farming practices, which have caused widespread damage to soils, ecosystems, waters and even the atmosphere. In fact, agriculture’s impacts are as bad as climate change as an environmental concern. Besides, we will have to improve food security for the world’s poor. While the Green Revolution of the 1960s made it possible to feed hundreds of millions more people than in earlier eras, the number of the under-nourished in the world has started to rise again. Finally, we will have to increase the recovering ability of agriculture from shocks. Today, our high-efficiency, globalized world has many benefits, but it is vulnerable (易受伤的) to destruction, whether from droughts, diseases or sudden price rises. We must start building better food systems to better keep us away from future shocks.
    Currently, there are two models of agriculture: local and organic agriculture vs. globalized and industrialized agriculture. Each has been strongly supported and severely criticized, but neither of these models, standing alone, can fully meet our needs.
    Organic agriculture teaches us important lessons about soils, nutrition and pest management. Unfortunately, organic food provides less than 1% of the world’s calories, mostly to the wealthy. It is hard to imagine organic farming developing to feed 9 billion. Globalized and industrialized agriculture has benefits of high output and low labor demands. Without it, billions of people would have starved. However, it has come with enormous environmental and social costs, which cannot be sustained.
    Rather than voting for just one solution, we need a third way to solve the crisis. Let’s take ideas from both sides, creating new, hybrid solutions that increase production, save resources and build a more sustainable agriculture.
    There are many promising avenues to pursue. A new “third way” for agriculture is not only possible but also necessary. Our problems are huge, and they will require everyone at the table, working together toward solutions.
    53. How many goals of agriculture are mentioned in the passage?
    A. Three           B. Four            C. Five             D. Six
    54. Which is true according to the passage?
    A. Organic agriculture can feed most people in the world now.
    B. Industrialized agriculture does no harm to our environment.
    C. Modern farming is criticized while organic farming is not.
    D. The future agriculture can’t only depend on organic agriculture.
    55. We can learn from the passage that _______.
    A. everyone can afford to enjoy organic food at will
    B. we will vote to decide which farming system to take
    C. the writer is quite optimistic about future agriculture
    D. only experts can find a better agricultural solution
    56. What’s the best title for the passage?
    A. Organic Agriculture Vs. Industrialized Agriculture.          
    B. The Goals of Future Agriculture and Its Way Out.      
    C. A Third Possible and Necessary Way for Agriculture.
    D. Modern Globalized and Industrialized Agriculture.

    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

    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

    D
    　　In the atmosphere,carbon dioxide actd rather like a one-way mirror or the glass in the roof of a greenhouse which allows the sun's rays to enter but prevents the heat from excaping.
    　　According to a weather expert's prediction,the atmosphere will be 3 warmer in the year 2050 than it is today, if man continues to burn luels at the present rate. If this warming up took place,the ice caps in the poles would begin to melt,thus raising sea level several meters and severely flooding coastal cities.Also，the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere(半球),psooicbly resulting in an alteration of earth's chief food growing zones.
    　　In the past,concern about a man - made warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet.But the weather experts are now paying more attention to West Antarctic,which may be affected by a warming on the scale that will possibly take place in the next fifty years from on burning of fuels.
    　　Satellite pictures showthat large areas of Antarctic ice are already disappearing.The evidence available suggests that a warming has taken place.This fits the theory that carbon dioxide warms the earth.
    　　However,most of the fuel is burnt in the northern hemisphere,where temperatures seem to be falling.Scientists conclude,therefore,that up to now natural influences on the weather have exceeded those caused by man.The question is:Which natural cause has most effect on the weather?
    　　One possibility is the variable behavior of the sun.Astronomers at one research station have studied the hot spots and cold spots(that is,the relatively less hot spots) on the sun. As the sun rotates(旋转),every 27.5 days,it presents hotter or colder faces to the earth,and different aspects to different parts of the earth.This seems to have a considerable effect on the distribution of the earth's atmospheric pressure,and consequently on wind circulation.The sun is also variable over a long term:its heat output goes up and down in cycles,the latest trend being downward.
    　　Scientists are now finding mutual relations between models of solar weather interactions and the actual climate over many thousands of years ,including the last Ice Age.The problem is that the models are predicting that the world should be entering a new Ice Age and it is not.
    　　One way of solving this theoretical difficulty is to assume a delay of thousands of years while the solar effects overcome the inertia(不活动，惰性) of the earth's climate.If this is right,the warming effect of carbon dioxide might thus be serving as a useful counter balance to the sun's diminishing heat.
    　　68.It can be concluded that a concentration of carbon dioxide in the atmosphere would ___.
    　　　A.mean a warming - up im the Arctic
    　　　B.raise the temperature of the earth's surface
    　　　C.prevent the sun's rays from reaching the earth's surface
    　　　D.account for great changes in the climate in the northern hemiphere
    　　69.Although the fuel consumption is greater in the northern hemisphere,temperatures there seem to be falling.This is _______.
    　　　A.mainly because the levels of carbon dioxide are rising
    　　　B.partly due to variations in the output of solar energy
    　　　C.possibly because the ice caps in the poles are melting
    　　　D.exclusively due to the effect of the inertia of the earth's climate
    　　70.On the basis of their models,scientists are of the opinion that ________.
    　　　A.the climate of the world should be becoming cooler
    　　　B.the new Ice Age will be delayed by the greenhouse effect
    　　　C.the man - made warming effect helps to increase the solar effects
    　　　D.it will take thousands of years for the inertia of the earth's climate to take effect

    B
    A new study has claimed that men really are more intelligent than women . The study concluded that men’s IQs are almost four points higher than women’s.
    British-born researcher John Philippe Rushton says the finding could explain why so few women make it to the top in the workplace.
    The Oxford University reached his conclusion after Scrutinizing the results of university ability tests taken by 100,000 students aged 17 and 18 of both sexes.
    A focus on the factors such as the ability to quickly grasp a complex concept , verbal reasoning skills(语言推理能力) and creativity—some of the key factors of intelligence ---showed the male teenagers had IQs that were an average of 3.63 points higher. The average person has an IQ around 100 . The findings , which held true for all classes and levels of education , overturn 100-year opinion that men and women average the same in general mental ability. They also conflict（冲突） with evidence that girls do better in school exams than boys.
    But Professor Rushton argues that the faster maturing（成熟） of girls leads to them outshining boys in the classroom .
    46. The report is mainly about________.
    A. a study that shows men are clever than women   B. the “glass ceiling “phenomenon
    C. Professor Ruston’s theory on IQ              D. the difference between male and female
    47. The underlined word “Scrutinizing” in the fourth paragraph probably means__________.
    A. making up      B. carrying out   C. examining carefully   D. looking at
    48. The tests were taken by _________.
    A. boy students aged 17 and 18.          B. 100,000 boy and girl students aged 17 and 18
    C. girl students aged 17 and 18           D. 100,000 girl students
    49. We can infer that the average woman has an IQ of _________.
    A. a little less than 100   B. 100    C. more than 100    D. 96.37
    50. Which of the following opinions does Professor Rushton NOT accept?
    A. Men’s IQs are almost four points higher than women’s
    B. Few women make it to the top in the workplace.
    C. Men and women average the same in general mental ability .
    D. The faster maturing of girls leads to them outshining boys in the classroom.

    D
    Global warming is the process of earth’s atmosphere heating up. Over the last 100 years, the average temperature of earth’s atmosphere has gone up 1 Fahrenheit. The weather has not changed exactly the same way in every area of the planet. But scientists think that the rise in average temperature is already affecting the earth’s climate.
    Many scientists now believe that global warming is caused by cutting down trees, producing more trash, and polluting the environment are some of the reasons that the temperature has gone up. Many scientists believe that the biggest causes of global warming are new human technologies that release greenhouse gases into the atmosphere.
    The greenhouse effect is not new. Certain gases in the atmosphere, like carbon dioxide, nitrous oxide and methane, prevent heat energy from escaping back into space. In the past, the climate didn’t change much because nature produced just the right amount of greenhouse gases to deal with it.
    Today, most scientists are pretty sure that the rising temperature can’t be blamed on nature. Ever since the industrial revolution in the 1700s, humans have relied on machines for daily life. And many of those machines give off a lot of greenhouse gases. An increase in the release of greenhouse gases from human activities is throwing nature off balance.
    The climate is a very complicated thing, but many scientists agree that the rising atmospheric temperature has already damaged the environment. Sheets of ice, called glaciers, are melting in Antarctica and other parts of the globe. As glaciers break off and melt into the oceans, they are adding warm water to the oceans and causing the sea level to rise.
    Over the past last 100years, the sea level has risen 6-8 inches around the world. That means land along the coasts is beginning to disappear under water. Bigger and warmer oceans are also adding to other weather problems caused by pollution in the atmosphere. Some places have received more rain, others have had bigger storms and a few areas in the world have experienced unusual droughts.
    68. What is mainly talked about in this passage?
    A. The melting of glaciers.                B. Global warming.
    C. The world’s weather.                  D. The earth’s temperature.
    69. What causes global warming according to scientists?
    A. Human activities.                     B. The nature itself.
    C. The earth’s atmosphere.                D. New discoveries
    70. How can greenhouse gases make the globe warm?
    A. They keep heat in the atmosphere   
    B. They let the heat go out into space.
    C. They release heat into the air.       
    D. They can make the other gases warm.
    71. From the passage we can see that global warming will bring about _________.
    A. the pollution in the atmosphere            B. natural disasters
    C. population pollution                     D. the rise of glaciers

    Research on the human brain has been attracting more and more scientists in recent years, just like the booming hi-tech industry. One of the latest research topics is how to change the human brain or combine the computer and the human brain, i.e. to transplant a chip into a human brain. This idea may make everyone’s dream come true. If we compare a human brain to a hard disc（硬盘）, what the scientists are doing is to enlarge the capacity of the hard disc. For the time being, there are some difficulties in such transplant experiments, but scientists never give up.
    Experiments have started on animals. In 1996, a transplant experiment performed at the Defense and Military Physiology Research Institute in the U.S. turned a bear into a dolphin.
    The dolphin was named Ted, and the bear was named Tallin. Using the most advanced technology available, deep and detailed images were made of the memory area in Ted’s brain containing information about swimming by the scientists. They obtained a series of useful information, the signals transferred by the nervous system. Such information was saved into a button-sized chip, which was then transplanted into the action memory area in Tallin’s brain. The information saved on the chip was released by means of electric power.
    Recently, another comprehensive memory transplant was performed at the Motor Nerve Research Institute of the University of California. The comprehensive memory transplanted in the experiment included actions, moods, logic, words, images, etc. The experiment involved an entire transplant of the memory area. This was the largest such experiment done so far.
    The transplant was performed making a transfer from a dog named “Genius” to a dog named “Idiot”. “Genius” could understand and follow up to 100 gestures and orders made by its master. It was a real genius in memorizing. “Idiot” was the younger brother of “Genius”. It had no contact with people at all since its birth. It became an animal with nothing in its brain, without any memory.
    The operation was a complete success. When the two dogs woke up, “Idiot” had grasped all the abilities “Genius” possessed; it was good at memorizing and sensible. It could follow every gesture and any command given by its master. But “Genius” gave no response to its master, and in fact did not recognize him at all.
    57. The purpose of the experiment is _____.
    A. to combine the computer and the human brain    
    B. to enlarge the capacity of human brain
    C. to make some stupid dog turn clever          D. to make bear swim
    58. Which of the following statements is TRUE?
    A. The scientists transferred a button-sized chip with useful information in Tallin’s brain.
    B. The first comprehensive memory transplant was performed at the Motor Nerve Research University.
    C. The second experiment wasn’t an entire transplant of the memory area.
    D. The Idiot was an animal with memory before brain experiment
    59. What does the underlined word “success” refer to?
    A. The two dogs woke up.
    B. They were both good at memorizing.
    C. The Idiot grasped all the abilities of Genius.
    D. The Genius grasped all the abilities of Idiot.
    60. According to the text, we can infer _____.
    A. a person can know more after the experiment
    B. a bear can swim after being transferred a chip with related useful information
    C. a dog can become clever after entire transplant of the memory area
    D. it is really good for animals to have been involved in the transplant experiment
