    In Wiltshire, England, volunteers are being sought to visit a nature protection area to count the butterflies living there and on surrounding fields. The project is promoted by all environmental protection organization, which has contributed to improving the living environment for wild animals. Recently, the organization has issued an appeal to help it observe environmental changes based on the record of butterflies and protect the environment.
    In the area, the local people have planted many special flowers with the help of the organization, aiming to see whether these flowers will interest the rare and beautiful butterflies. The project officer Sarah Marshall says,“It will be a suitable habitat (栖息地) for butterflies. They are great‘indicator species’ as they are easily affected by climate changes so they make a brilliant early-warning system for the environment.” She also points out that volunteers are needed to record the number or species of butterflies, and based on the change happening to the butterflies, the hidden environmental problems in the area can be found out in time.
    The organization is seeking volunteers to help monitor butterflies from April through to September. They will walk a fixed route and record the different butterflies they encounter along the way. Each visit should take no more than two hours, and each volunteer is expected to visit once a month to count the wildlife. “Staff will provide back up, so if the weather is poor on the day you are to visit (butterflies don’t like to fly in the rain, wind or if it’s too cloudy) we can have someone else do your job,” Sarah points out.
    No previous experience is necessary as training and support will be provided, but a keen interest is essential. If you are interested please contact Sarah on (01380) 725670, ext 278, email—sarahm @ wiltshirewildlife. org.

    Life on earth depends on water, and there is no substitute for it. The current assumption is that our basic needs for water—whether for drinking, agriculture, industry or the raising of fish—will always have to be met. Given this premise (前提), there are two basic routes we can go; more equal access to water or better engineering solutions.
    Look at the engineering solutions first. A lot of my research concentrates on what happens to wetlands when you build dams in river basins, particularly in Africa. The ecology of such areas is almost entirely driven by the seasonal changes of the river—the pulse of the water. And the fact is that if you build a dam, you generally spoil the downstream ecology. In the past, such problems have been hidden by a lack of information. But in the near future, governments will have no excuses for their ignorance.
    The engineers’ ability to control water flows has created new kinds of unpredictability, too. Dams in Africa have meant fewer fish, less grazing and less floodplain (洪泛区) agriculture, none of which were expected. And there average economic life is assumed to be thirty years. Dams don’t exist forever, but what will replace them is not clear.
    The challenge for the future is to find new means of controlling water. Although GM technology(转基因) will allow us to breed better dry-land crops, there is no market for companies to develop crops suitable for the micro-climates of the Sahel and elsewhere in Africa. Who is going to pay for research on locally appropriate crops in the Third World?
    小题1:What’s the main idea of this passage?
    A．The engineering solutions to water resource and their limitation.
    B．The challenge for the future.
    C．The basic means of controlling water.
    D．The challenge for developing crops.
    小题2:The author suggests that governments will have no excuse for their careless ignorance in the future because _____.
    A．The ecological destruction will be known to the public by researchers
    B．The ecological destruction will no longer be a problem in the future
    C．The future is an information age
    D．Governments will face greater challenge in the future
    小题3:Which of the following statements is NOT true for meeting our basic needs for water?
    A．Water resource should be used more reasonably.
    B．More dams should be built in river basins.
    C．More wetlands should be protected from destruction.
    D．More dry-land crops could be developed in Africa.
    小题4:The last sentence probably implies that _____.
    A．No one will invest in developing locally appropriate crops in Africa
    B．Researchers have no interest in developing dry-land crops
    C．Research on locally appropriate crops in the Third World may be profitable
    D．There is less water resource in the Third World

    What do butterfly wings have to do with computer screens? What do birds have to do with high speed trains?
    These may sound like strange things to put together. But scientists, inventors, and designers are doing just that. They are learning from nature to create new technology.
    The word biomimicry (仿生学) combines two words: biology and mimicry. So people using biomimicry try to use examples in nature to design new technology.
    Biomimicry is not a new idea. People have been studying nature for hundreds of years. Leonardo DaVinci used birds as models to invent his flying machine. And when the Wright Brothers made the first successful airplane, they also studied birds. In 998, Janine Benyus, a natural science writer and teacher, wrote a book about biomimicry. To develop her interest in the subject, Janine Benyus started the Biomimicry Institute.
    The Biomimicry Institute is a non-profit organization. It brings together scientists, designers, inventors and many other people. It offers classes to teach people biomimicry. It provides money for people to research and test new technologies. And it wants all people, from children to adults, to think about new ways to learn from nature.
    People involved with the Biomimicry Institute believe that biomimicry can help solve many of the world’s problems. Often, new technologies can harm nature, but this is not true for biomimicry. Let’s look at some examples.
    Butterflies have colorful wings because light shines off them in a special way. Scientists want to copy these same ways to make light shine off computers. They hope this will make for more colorful screens.
    Another example of biomimicry is the bullet train. It travels at speeds of over 250 kilometers per hour! But it had a problem: it made too much noise!
    Through the observation of birds, scientists thought about a kind of bird, the kingfisher(翠鸟). The kingfisher can dive into water without making any noise because of the shape of its beak(喙). Researchers thought that if they could design the front of the train like this beak, the train would be quieter. Well, it worked!
    小题1:The first paragraph is written to_____.
    A．start a discussion B．make a brief summary
    C．introduce the topic of the text D．test readers' knowledge on science
    小题2:Why did Janine Benyus set up the Biomimicry Institute?
    A．To honor the Wright Brothers.
    B．To show her recent inventions.
    C．To gather talented people for her research.
    D．To explore the link between nature and technologies.
    小题3:We know from the text that the Biomimicry Institute _____.
    A．earns a lot by giving classes on biomimicry B．tells people about their technologies
    C．gives free support to scientists D．teaches children about birds
    小题4:The author gives the two examples at the end of the text to show _______.
    A．biomimcry works harmoniously with natureB．the fast development of modern technology
    C．how biomimcry changes our lifeD．how nature inspires scientists
    小题5:What’s the main idea of the text?
    A．Biomimicry is widely used in the world.
    B．People copy nature to create new technologies.
    C．The Biomimicry Institute was set up for science.
    D．Birds play an important part in new technologies.

    There is no question that teenagers need rules, which is often not a difficult thing for parents to give. What can be more challenging is giving teenagers their freedom. It can be difficult to draw the line between the two. However, some issues cannot be changed by discussion and require firm rules. For instance, rules should be established concerning driving the family car.
    I will admit that I have no problem coming up with rules. To me they make life easier and they leave no room for questioning. What can be more difficult, however, is giving my teens their freedom. I guess there are really two primary reasons for this. One is that I sometimes am afraid to give them freedom. The second is that I’m not always so sure what the freedom should be.
    It helps that I have a husband with whom I can discuss these problems. We talk about them, give our thoughts and then we come up with an agreement. Sometimes one of us might be more unwilling but we know that there comes a time when we really do have to learn how to let go of the reins (缰绳) a bit.
    If we try to make life have nothing but rules, we are more likely to see our teen’s rebelling (反抗). They need to know that while we do have certain expectations, we also trust them to begin making their own choices and decisions. How else can they do that unless they are given the space and room to do it?
    It’s really all about balance and I will be the first to admit that it can be a challenge to carry out. However, it is a necessary part of growing up. Yes, teens definitely need rules but they also need freedom.
    小题1:According to the text, we can infer that the writer________.
    A．refuses to give her children freedom
    B．finds it difficult to make rules
    C．doesn’t have a good relationship with her children
    D．has trouble in giving freedom to her children
    小题2:According to the writer, only rules without freedom will make the children _______.
    A．strong-willedB．rebelliousC．weakD．independent
    小题3:Which of the following is TRUE according to the text?
    A．Rules are difficult to make for parents.
    B．Rules and freedom are similarly important.
    C．We should give children freedom as much as possible.
    D．Rules are more important than freedom.
    小题4:What does the underlined word “them” in Paragraph 3 probably refer to?
    A．Problems.B．Children.C．Rules. D．Reasons.

    Anne Whitney, a sophomore (大学二年级学生) at Colorado State University, first had a problem taking tests when she began college. "I was always well prepared for my tests. Sometimes I studied for weeks before a test. Yet I would go in to take the test, only to find I could not answer the questions correctly. I would blank out because of nervousness and fear. I couldn't think of the answer. My low grades on the tests did not show what I knew to the teacher. “Another student in biology had similar experiences. He said, "My first chemistry test was very difficult. Then, on the second test, I sat down to take it, and I was so nervous that I was shaking. My hands were moving up and down so quickly that it was hard to hold my pencil. I knew the material and I knew the answers. Yet I couldn't even write them down!"
    　　These two young students were experiencing something called test anxiety. Because a student worries and is uneasy about a test, his or her mind does not work as well as it usually does. The student cannot write or think clearly because of the extreme tension and nervousness. Contrary to people’s common belief that poor grades are often a result of poor study habits, sometimes test anxiety plays a role in students’ achieving low grades. Recently, test anxiety has been recognized as a real problem, not just an excuse or a false explanation of lazy students.
    　　Special university advising courses try to help students. In these courses, advisors try to help students by teaching them how to manage test anxiety. At some universities, students take tests to measure their anxiety. If the tests show their anxiety is high, the students can take short courses to help them deal with their tensions. These courses teach students how to relax their bodies. Students are trained to become calm in very tense situations. By controlling their nervousness, they can let their minds work at ease. Learned information then comes out without difficulty on a test.
    　　An expert at the University of California explains, " With almost all students, relaxation and less stress are felt after taking our program. Most of them experience better control during their tests. Almost all have some improvement. With some, the improvement is very great. "
    小题1:To "blank out" is probably______.
    A．to be like a blanket B．to be sure of an answer
    C．to be unable to think clearlyD．to show knowledge to the teacher
    小题2:Poor grades are usually believed to be the result of______.
    A．poor sleeping habit B．laziness
    C．test anxiety D．inability to form good study habits
    小题3:Test anxiety has been recognized as______.
    A．an excuse for lazinessB．the result of poor study habits
    C．a real problem D．something that cannot be changed
    小题4:A University of California advisor said______.
    A．all students could overcome the anxiety after taking a special test anxiety program
    B．almost all students felt less stress after taking a University of California advising course
    C．students found it difficult to improve even though they had taken a special test anxiety course
    D．students found it easy to relax as soon as they entered a University of California advising course

    Over the past decade, cheating—an act of academic dishonesty—has become more and more common.
    The latest statistics shows more than two thirds of high school students admitted cheating on an exam last year, and—even more surprising—often the best students cheat to get to the top of their class—and they don’t think it is wrong. It’s not a big deal. Everybody is doing it.
    It is a big deal! Cheating is basically wrong and must be punished.
    If students easily get away with it, they might be encouraged to do it again. They won’t realize that this—in the broadest sense—is an attack on our society, which is based on values like honesty and fairness. The present spreading of cheating indicates a loss of those values and cannot be tolerated. An appropriate punishment for cheating incidents would make students aware of their misbehavior.
    If no one were punished for cheating, who would ever study for an exam? Tons of papers would be lifted from websites, writing crib sheets would be more important than reviewing the subjects, and highly sophisticated cheating arts would be invented. Knowledge would only exist on the Internet and on cleverly created cheat sheets, but not in the minds of the students—a rather bad precondition to enrich our society wisely and intelligently.
    Students have to learn that they have to learn. Only doing what’s right will bring them a feeling of pride and accomplishment and create self-confidence—the building blocks for a successful and satisfying life and a society that keeps its values.
    小题1:What is more surprising is that       .
    A．cheating is very common in schools
    B．over 2/3 of the students cheat last year
    C．even the best students cheat on exams
    D．teachers are not aware of the problems
    小题2:How do they make the students realize their misbehavior?
    A．By letting them getting away with it.
    B．By telling them what is right.
    C．By catching them on the spot.
    D．By giving them some punishment.
    小题3:How can students create self-confidence?
    A．By knowing they have to learn.
    B．By doing what is right.
    C．By learning the right things.
    D．By being punished when cheating.
    小题4:What does the underlined word “lifted” mean?

    Across countryside, non-food crops are growing alongside wheat．Some are used in new alternatives to plastics and other materials, but others will simply be burned．
    Burning crops is becoming more popular because it is good for the planet．Doing so is also cheaper than burning fossil fuels．As more land is devoted to non-food crop production, the economics of crops for fuel are likely to become even more favorable．
    Humans have been burning such biomass—organic materials from plants or animals— since they discovered fire．But that burning fossil fuels could have catastrophic consequences has brought biomass back into fashion．
    Even allowing for emissions (排放) of carbon dioxide from fuel used in planting, harvesting, processing and transporting biomass fuel, replacing fossil fuel with biomass can typically reduce greenhouse gas emissions by more than 90 percent．
    Power stations around the world are experimenting with forms of biomass to add to their coal or oil, with encouraging results．Indeed, power companies could profit by turning to biomass, especially when the subsidies (补助) many governments offer for using renewable energy are taken into account．
    Farmers can benefit from growing biomass．In Europe, the reduction of subsidies for certain crops is exposing farmers to market forces．Instead of being paid for whatever they produce, farmers must seek a clear demand for their product．Many believe that the demand for alternatives to fossil fuels could be just such a driver．
    But while biomass offers a variety of potential alternatives, the world's infrastructure (基础设施） has developed around burning fossil fuels to such a stage that switching to biomass involves a change in conception that many companies have not accepted．
    Also, there are problems with using biomass．Although most coal-fired power stations could take a small amount of their fuel from biomass without significant adjustment, few are built to run on biomass alone．Burning some forms of biomass also causes environmental problems．Oils and waste can be smelly, while wood produces smoke unless burned properly．
    The supply chains for fossil fuels are set up well, but those for biomass are just the beginning. Sources of supply for biomass rely on farm production and can therefore be less reliable. They are necessarily limited and it wouldn't make sense to turn a very large amount of valuable agricultural land away from food crops．But as the world adjusts to the need to control greenhouse gas emissions, these problems may receive more attention．
    小题1:What do we know about biomass?
    A．It is a useful way of burning crops．
    B．It is plant and animal matter used to provide power．
    C．It is a new alternative to be used widely．
    D．It is a popular approach to fighting against pollution．
    小题2:What are the advantages of using biomass?
    a．It gives off less greenhouse gases．
    b．It helps farmers receive subsidies for what they produce．
    c．It has met the clear demand for energy．
    d．It has brought subsidies for some power companies．
    e．It is cheaper than burning fossil fuels．
    A．a, b, cB．b, c, dC．c, d, eD．a, d, e
    小题3:For coal-fired power stations, ______．
    A．more effective ways to use biomass have been tried
    B．using renewable energy has become their daily task
    C．burning biomass alone would require considerable changes
    D．setting up dependable supply channels needs governments' support
    小题4:What is the author's attitude towards biomass fuels?
    A．Defensive．B．Doubtful．C．Negative． D．Objective
