    Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain-computer interface(BCI) technology could help people with disabilities send commands to machines.
    Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic school in Lausanne, Switzerland, demonstrated（展示）a small robotic wheelchair directed by a person’s thoughts.
    In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right band. He could even talk as he watched the vehicle and guided it with his thoughts.
    “our brain has billions of nerve ceils. These send signals through the spinal cord （脊髓）to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles,” Tavella says.  “Our system allows disabled people to communicate with external world and also to control devices.”
    The researchers designed a special cap for the user. This head cover picks up the signals from the scalp(头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.                                               
    Prof. Millan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. “The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices. One example is this wheelchair.”
    He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit frotn. And the other is to guarantee that they can use the technology over long periods of time.
    小题1:
    BCI is a technology that can              
    A．help to update computer systemsB．link the human brain with computers
    C．help the disabled to recoverD．control a person's thoughts
    小题2:
    How" did Tavella operate the wheelchair in the laboratory?
    A．By controlling his muscles.B．By talking to the machine.
    C．By moving his hand.D．By using his mind.
    小题3:
    Which of the following shows the path of the signals described in Paragraph 5?
    A．scalp→computer→cap→wheelchair
    B．computer→cap→scalp→wheelchair
    C．scalp→cap→computer→wheelchair
    D．cap→computer→scalp→wheelchair
    小题4:
    The team will test with real patients to
    A．make profits from themB．prove the technology useful to them
    C．make them live longerD．learn about their physical condition
    小题5:
    Which of the following would be the best title for the text?
    A．Switzerland, the BCI Research Center
    B．New Findings About How the Human Brain Works
    C．BCI Could Mean More Freedom for the Disabled
    D．Robotic Vehicles Could Help to Cure Brain Injuries

    Broken rubber bands and flat tires requiring replacement could soon be a thing of the past．
    French researchers have developed a new kind of rubber that can repair itself when broken．The new rubber is made from widely available materials including vegetable oil and a common industrial chemical．All the materials are considered safe to the environment and can be easily reused．
    The best part is that the new rubber can be repaired and used again and again without losing its strength or ability or stretch．When cut, the rubber can be made new again, simply by pressing the two broken ends back together．
    The product can be repaired at room temperature, around twenty degrees Centigrade；other self-healing materials require higher temperatures for repair．
    Traditionally, rubber substances are made from huge molecules（分子）connected by strong chemical links, or bonds．The new rubber is made of smaller molecules．The molecules are linked together using hydrogen bonds．When connected in this way, the molecules act like one long molecule, forming what is called supramolecular networks（超分子网）．When the rubber is cut, the molecules attempt to connect with whatever molecule is near them．When pressed together, the molecules are able to repair themselves at the molecular level, making the repaired rubber like new．
    However, time is an important element in the process．If the broken ends are not brought together quickly, a repair is not possible．This is because molecules will form bonds with molecules on their own side．The inventors say the surfaces of the rubber can be repaired within a week of being separated．
    The rubber is the creation of scientists at the Industrial Physics and Chemistry Higher Education Institution in Paris．The organization is part of France’s National Center for Scientific Research．The new material is described in greater detail in the research publication Nature．
    小题1:According to the introduction, which of the following is NOT the advantage of the new rubber?
    A．It can be made as easily as common rubber．
    		B．It is environmentally-friendly．
    		C．It can repair itself at room temperature．
    		D．It is made of smaller molecules．
    小题2:What does the 5th paragraph mainly tell us?
    A．Why the new rubber is unique．
    		B．Why the new rubber can repair itself．
    		C．The new rubber is made from huge molecules．
    		D．The new rubber is different from the common rubber．
    小题3:If we want to know more about the technology of this kind of new rubber, where can we get the information?
    A．In the researchers’ diary．B．In a guide book．
    		C．In a research magazine．D．In a newspaper．

    Twenty-five years ago if you made a trip to the local library and searched for articles on globing warming, you’d probably come up with a few from the leading magazines in the world. As an Internet search on global warming now shows, the subject has become as rooted in people’s mind as Madonna or microwave cooking.
    With the possible exception of another world war, a giant planet, or an incurable disease, global warming may be the largest danger to our planet. For decades human factories and cars have sent billions of tons of greenhouse gases into the atmosphere, and the climate has begun to show some signs of warming. If steps are not taken soon to reduce the amount of carbon dioxide sent into the atmosphere, the result could terribly affect human life. We have already seen growing destruction, such as drought and death in Sudan, flooding in Asia, bush fires in Indonesia, and fierce winter storms in central Europe.
    The Republic of Maldives is barely above sea level. Its 250, 000 citizens are scattered across 1,200 islands in the Indian Ocean. A strong typhoon could spell the end for the entire country, as sea levels could continue rising. The entire population would have to be moved away as the country disappears under the sea.
    The greenhouse effect is a naturally occurring phenomenon that keeps our planet at a comfortable temperature averaging 60°F. Since the mid-nineteenth century, however, carbon dioxide in the atmosphere has increased nearly 30% because of the increased use of fossil fuels to run cars, heat homes and power factories. Without controlling, the amount of carbon-dioxide by 2100 may increase by 30%-150% and could lift the average global temperature by up to 2.5° F the next 50 years.
    小题1:.
    With the first paragraph, the author intends to       .
    A．scold people for not paying enough attention to global warming
    B．draw people’s attention to global warming
    C．how to search for the articles on global warming
    D．point out the serious effect of global warming
    小题2:.
    Global warming could affect human life in the following ways EXCEPT       .
    A．producing more greenhouse gasesB．causing more floods
    C．making winter storms fiercerD．starting more bush fires
    小题3:.
    The Republic of Maldives       .
    A．has moved away their citizens
    B．will be more likely to be destroyed by a strong typhoon than by the rising sea level
    C．is mostly likely to be destroyed by the rising sea level
    D．will have to move away most of their population
    小题4:.
    . Why is the Republic of Maldives especially mentioned in the passage?
    A．Because smaller countries are easier to be affected by global warming.
    B．Because seaside countries are in danger of disappearing.
    C．Because it’s necessary to rescue a country before the sea level rises.
    D．Because the serious result of global warming could end a whole country.
    小题5:.
    . From the last paragraph, we can infer that greenhouse effect       .
    A．can only affect the earth in an unfavorable way
    B．is something easy to control
    C．is caused by human act
    D．will be good to us if it remains at a proper level

    Recently,university students around the world were asked to volunteer in a global experiment called Unplugged.It was designed to see how young people would react if they were asked to observe a total media ban by unplugging all forms of media devices for 24 hours.
    Unplugged is being run by Dr Roman Gerodimos，a lecturer in Communication and Journalism at Bournemouth University.During the experiment，Dr Gerodimos said there were already  signs of how much the exercise affected volunteers.He said：“They’re reporting withdrawal symptoms，overeating，feeling nervous，isolated and disconnected.”
    During their 24-hour test，three of the experiment’s participants were followed around by a BBC reporter plus cameraman.They were asked to write down 100 lines about their day offline，but of course，they all waited until the next day when they had access to their laptops.
    Elliot Day wrote：“Today,my whole morning routine was thrown up into the air.Despite being  aware of the social importance of the media,I was surprised by how empty my life felt without the radio or newspapers.”
    From Caroline Scott，we read：“I didn’t expect it，but being deprived of the media for 24 hours resulted in my day-to-day activities becoming so much harder to carry out than usual…I didn’t break out in a cold sweat like our lecturer expected us all to，but It’s not something l would like to do again！”
    And Charlotte Gay wrote：“I have to say the most difficult item for me to be without has been  my  mobile；not  only is it a social device，it’s  my main access point of communication.”
    Earlier in the year,a UK government study found that in the UK we spend about half our waking hours using the media,often plugged into several things at once.So,with technology continuing to develop at an alarming rate,how much time will you set aside for sleep in the future?
    小题1:What can we learn about the volunteers?
    A．Volunteers didn’t write down about their day offline.
    B．Volunteers weren’t allowed to use any media for 24 hours.
    C．Volunteers were followed around by Dr Roman Gerodimos.
    D．Only volunteers in the UK took part in Unplugged experiment.
    小题2:Which of the following is NOT mentioned about the participants’feelings？
    A．Anxious. B．Lonely C．Bored.D．Despaired.
    小题3:Which of the following is true of Caroline Scott？
    A．The media ban affected his temperature.
    B．His work went on smoothly without the media.
    C．His work was carried on hard without the media.
    D．His life was empty without the radio or newspapers.
    小题4:What can be inferred from the last paragraph?
    A．People should use the media devices reasonably.
    B．People can easily survive the media devices addict.
    C．People can spend more time sleeping in the future.
    D．People spend about half the time using the media devices.

    A new study has been carried to test the role of story telling in lowering blood pressure. Dr. Thomas Houston, a professor of the University of Massachusetts Medical School, led a group of scientists that researched how pre-recorded videos of hypertension (高血压) patients' talking about their medical histories helped another group of patients with high blood pressure to control their condition over several months.
    Houston was surprised by their studies that suggested that communication can be a powerful tool in medicine. They showed that those who had had similar experiences, when talking to someone with a similar background, could help change their behavior to become healthier. Hypertension is difficult to control, since it is dependent on diet, exercise and mental state. Medical treatments with drugs, and lifestyle therapies(疗法) have been relatively ineffective because people find it hard to follow those medical requirements.
    In the test, his team carefully chose their story-tellers from 230 members of a patients' community with whom they could most easily relate. Next, they divided their study population into two groups. One received three interactive DVDs containing the tellers' stories of their experiences in living with and treating their hypertension. The other were given educational discs on an unrelated health topic. The study volunteers reported that they had listened to the DVDs, and after three months, those who heard the stories of the hypertensive patients lowered their blood pressure.
    While the study did not address how the story-telling influenced the patients' behavior, Houston doubts that watching patients of similar backgrounds who had a similar medical experience helped to motivate them to seek medical help to their hypertension. They found that after six months the difference in blood pressure between those who watched the story-tellers and those who observed the unrelated videos remained, suggesting that the story-telling continued to have an effect.
    小题1: We can learn from the text that the pre-recorded videos _________.
    A．tell medical histories of hypertension patients
    B．introduce some medical treatments of hypertension
    C．introduce a good lifestyle for hypertensive patients
    D．tell scientific discoveries of the scientist group
    小题2:Houston was surprised to find that _______.
    A．hypertension is really difficult to control
    B．communication has some medical effects
    C．medical treatments have no effect at all
    D．people don't follow the medical requirements
    小题3: The underlined word "address" in the last paragraph most probably means _______.
    A．persuadeB．observeC．attend D．announce
    小题4: Which of the following could be the best title of the text?
    A．The stories of some hypertension patients.
    B．Medical treatments of blood pressure.
    C．Storytelling may help lower blood pressure.
    D．Suggestions about how to lower blood pressure.

      Dolphins and sharks are showing up in surprisingly shallow water just off the Florida coast．Mullets，crabs，rays and small fish gather by the thousands off an Alabama pier．Birds covered in oil are crawling（爬）deep into marshes（沼泽），never to be seen again．
    Marine scientists studying the effects of the BP disaster（英国石油公司漏油事件）are seeing some strange phenomena．Fish and other wildlife seem to be fleeing the oil out in the Gulf and gathering in cleaner waters along the coast in a trend that some researchers see as a potentially troubling sign．The animals.presence close to shore means their usual habitat is badly polluted，and the crowding could result in mass die-offs as fish run out of oxygen．Also，the animals could easily be captured by their enemies．
    The nearly two-month-old spill（漏油）has created an environmental disaster in US history as tens of millions of gallons have flown into the Gulf of Mexico ecosystem．Scienfists are seeing some unusual things as they try to understand the effects on thousands of species of marine life．For nearly four hours Monday，a three-person crew with Greenpeace cruised（巡航）past delicate islands and mangrove-dotted inlets in Barataria Bay off southern Louisiana．They saw dolphins by the dozen frolicking（嬉戏）in the oily sheen（光泽）and oil-tinged pelicans feeding their young．But they spotted no dead animals．
    “I think part of the reason why we’re not seeing more yet is that the impacts of this crisis are really just beginning，”Greenpeace marine biologist John Hocevar said．
    The counting of dead wildlife in the Gulf is more than an academic exercise；the deaths will help determine how much BP pays in damages．
    小题1:What do the marine life react to the BP disaster？
    A．Dolphins and sharks show up in deep water．
    B．Tens of thousands of marine animals are found dead．
    C．Sea creatures flee from oil spill，gathering near seashore．
    D．Birds crawl（爬）deep into caves．
    小题2:The environmental disaster was caused by       ．
    A．the lack of environmental sense of BP
    B．the nearly two-mouth-old oil spill
    C．the crowding marine life
    D．the damage of Mexico Gulf ecosystem
    小题3:What is John Hocevar’s attitude towards the disaster？
    A．DisappointedB．DepressedC．NeutralD．Worried
    小题4:From the passage，we can infer that         ．
    A．marine scientists have seen some strange phenomena．
    B．the disaster has little influence on dolphins．
    C．a three-person crew reached no conclusion．
    D．BP will pay much money according to the number of dead wildlife there．

    Light travels at a speed which is about a million times faster than the speed of sound. In one second, light travels about 300,000km, but sound travels only 344m. You can get some idea of this difference by watching the start of a race. If you stand some distance away from the starter, you can see smoke come from his gun before the sound reaches your ears. This great speed of light produces some strange facts. Sunlight takes about 8 minutes to reach us. If you look at the light of the moon tonight, remember that the light rays（光线）left the moon 1.3 seconds before they reached you. The nearest star is so far away that the light which you can see from it tonight started to travel towards you four years ago at a speed of nearly 2 million km per minute. In some cases the light from one of tonight’s stars started on its journey to you before you were born.
    Thus, if we want to be honest, we cannot say “ The stars are shining tonight.” We have to say, “ The stars look pretty. They were shining four years ago but their light has only just reached Earth.”
    小题1: Light speed is ________ than sound speed.
    A．millions times fasterB．a million times slower
    C．about millions of times fasterD．about a million times faster
    小题2:If you stand 200 meters away from a man who is firing a gun to start a race, you will find out that _____.
    A．you can hear the gun before you see the smoke.
    B．sound does not travel as fast as light.
    C．the sound of the gun will reach you before the man fires his gun.
    D．sound travels about a million times faster than light.
    小题3:What does “ it” refer to?
    A．moon lightB．light raysC．the nearest starD．the moon
    小题4:The scientific way of saying “ The stars are shining tonight” should be________.
    A．the stars have been shining all the time.
    B．the stars seen tonight will be shining four years later.
    C．the stars were shining long ago but are seen tonight.
    D．the starlight seen today could be seen four years ago.

    As children face their final month of revision before the exam season starts, many parents are looking for the words to motivate their offspring．But could they be mistakenly praising the value of ability over effort, asks Matthew Syed．
    Take a glance at these expressions of encouragement:
    "You learned that so quickly, you're so smart!"
    "Look at that drawing．Are you -the next Picasso or what?"
    They appear as the kind of confidence-boosting statements that should be given to children or, indeed, anyone else．Such phrases are used in homes and classrooms every day, particularly with exams approaching．
    Intelligence-based praise leads the receiver towards the fixed thought —it suggests to them that intelligence is of primary importance rather than the effort through which intelligence can be transformed．
    Let's take a quick second look into the science of expertise, and ask a question．Where does excellence come from? For a long time, it was thought the answer to this depended, to a large degree, on genetic inheritance．Or, to put it another way, it is all about talent．
    It turns out that this is mistaken．Dozens of studies have found that top performers—whether in maths, mi sic or whatever—learn no faster than those who reach lower levels of achievement—hour after hour, they improve at almost the same rates．
    The difference is simply that high achievers practice for more hours．Further research has shown that when students seem to possess a particular gift, it is often because they have been given extra tuition at home by their parents．
    This is not to deny that some kids start out better than others—it is merely to suggest that the starting point we have in life is not particularly relevant．
    Why? Because, over time, with the right, kind of practice, we change so dramatically．It is not just the body that changes, but the brain．The question of talent versus effort would not matter terribly much if it  as merely theoretical．But it is so much more than that．It influences the way we think, feel, and the way we engage with our world．
    小题1:What is the best title of this passage?
    A．The Words That Could Encourage Your Child
    B．Intelligence Says All
    C．High and Low Achievers
    D．Start Early, Learn More
    小题2:Which statement is intelligence-based praise?
    A．"You're so brilliant - you passed that exam without really studying!"
    B．"With more efforts, you can achieve more!"
    C．" You combine study with entertainment so well!"
    D．"You study so hard even when you are so good at it!"
    小题3:The writer thinks the answer to the question of talent versus effort is _____．
    A．simpleB．complicatedC．obviousD．mysterious
    小题4:Why do some people have higher achievements?
    A．Because they are born with great talent.
    B．Because they start better than others.
    C．Because they spend more of their spare time practicing what they have learnt.
    D．Because they improve themselves at almost the same rates.
