    Think about the different ways that people use wind. You can use it to fly a kite or to sail a boat. Wind is one of our cleanest and richest power sources, as well as one of the oldest. Evidence shows that windmills (风车) began to be used in ancient Iran back in the seventh century BC. They were first introduced to Europe during the 1100s, when armies returned from the Middle East with knowledge of using wind power.
    For many centuries, people used windmills to grind (磨碎) wheat into flour or pump water from deep underground. When electricity was discovered in the late 1800s, people living in remote (偏僻的) areas began to use them to produce electricity. This allowed them to have electric lights and radio. However, by the 1940s when electricity was available to people in almost all areas of the United States, windmills were rarely used.
    During the 1970s, people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity. People also realized that the supply of coal and gas would not last forever. Then, wind was rediscovered, though it means high costs. Today, there is a global movement to supply more and more of our electricity through the use of wind.

    Over 70 percent of the "double single-child couples" in China need help from their parents in taking care of their own kids, according to a recent survey.
    "Women of China" magazine and a consulting company carried out a survey recently on young couples of the "single-child" generation, the Morning Post reports. The couples surveyed were around 29 and have been married for three years on average, with university education and monthly income of 4.000 yuan ($531). Among them, 43.5 percent have kids.
    Results show that 71.9 percent of the young couples have help from their parents in taking care of their kids.
    Grown up as the "single-child", the only child in a family since the family planning policy was adopted in 1979, this generation depends much on their parents.
    The parents of the "single-child" generation focused more on their children's physical well-being rather than their attitudes and values, according to some psychologists.
    The research also found that the "double single-child couples" follow a rather traditional value system.
    Survey shows that 27.5 percent of them got married after dating for one to two years, 25.2 percent two to five years, and 20 percent didn't tie the knot until dating for five years. Also, 30 percent of the couples were schoolmates, while 43.8 percent were introduced by someone.
    Since their marriage are based on enduring relationships, 65.2 percent of the husbands and 62.9 percent of the wives think that compromise(妥协)and tolerance(宽容)are necessary in their marriage. Meanwhile, 21.7 percent of the husbands and 37.1 percent of the wives support the idea that happiness is the key standard for a marriage.

    Traders were expecting market liquidity to remain thin on Friday because of the extended U.S. holiday.
    In such thin trading, many said a fall in the dollar past 102 yen and US$1.33 per euro was a real possibility.
    Referring to recent currency movements as “brutal”, European Central Bank chief Jean-Claude Trichet, who is the most vocal European policymaker on dollar weakness, is due to make comments in Rio de Janeiro, along with ECB council member and Spanish central bank governor Jaime Caruana.
    Introduced in 1999 as the common currency for 12 European countries, the euro initially(最初) dropped against the dollar but has risen some 60 percent since hitting an all-time low of 82 U.S. cents in October 2000.

    WASHINGTON, Sept. 23 — The House of Representatives, which prides itself on being " the People’s House" has been turning into, a rich men’s club.
    The representatives newly elected in 1984 were almost four times as wealthy as the first term lawmakers elected only six years before, according to a new study on the members’ financial reports.
    Behind this remarkable swing, the study says, there are two main factors: a court decision that outlawed limits on what candidates could give to their own campaigns, and the enormous growth in the cost of pursuing a seat in Congress. As a result, it is increasingly difficult for candidates of modest means, particularly women to amount successful challenges to entrenched office holders.
    One solution, the authors contend, is a system of public financing for campaigns, but Congress seems in no mood to change the political rules any time soon.
    "The lower chamber is going upper class," said Mark Green, the President of the Democracy Project, a public policy institute based in New York. ".But this evolution from a House of Representa­tives to a House of Lords denies the diversity of our democracy. It establishes a de facto property qual­ification for office that increasingly says: The people with low and middle income need not apply. "
    The Democracy Project produced the study in cooperation with the United States Public Interests Research Group, a similar institute situated in Washington. But their research was not entirely theo­retical. In 1980 Mr. Green was the unsuccessful Democratic candidate for Congress in New York’s 15th District, in Manhattan. The winner was. Bill Green, one of the wealthiest members of Congress.
    5. What can we know from the passage?
    A. The House of Representatives is poor men’s club.
    B. The House of Representatives was made up of people with low and middle income.
    C. The House of Representatives, was rich men’s club;
    D. The House of Representatives is made up of people with low and middle income.
    6. What does "this remarkable swing" in the third paragraph refer to?
    A. The House of Representatives prides itself on being" the people’s House".
    B. The new study based on the members’ financial reports.
    C. A court decision that outlawed limits on what candidates could give to their own campaigns.
    D. The representatives elected now are much wealthier than those elected a few years ago.
    7. Which of the following is wrong according to the study?
    A. Any honest man can become a representative of the House.
    B. Women are more difficult than men to be an entrenched office holder.
    C. Limits on what a candidate could give to his campaign are outlawed.
    D. One must spend much money getting a seat in the Congress.
    8. What is the United States Public Interests Research Group like?
    A. The House of Representatives.
    B. A public policy institute based in New York.
    C. A public policy institute based in Washington.
    D. The House of Lords.

    If you want to stay young, sit down and have a good think. This is the research finding of a team of Japanese doctors, who say that most of our brains are not getting enough exercise—and as a result, we are aging unnecessarily soon.
    Professor Taiju Matsuzawa wanted to find out why otherwise healthy farmers in northern Japan appeared to be losing their ability to think and reason at a relatively early age, and how the process of aging could be slowed down.
    With a team of colleagues at Tokyo National University, he set about measuring brain volumes of a thousand people of different ages and varying occupations.
    Computer technology enabled the researchers to obtain precise measurements of the volume of the front and side sections of the brain, which relate to intellect (智能) and emotion, and determine the human character. (The rear section of the brain, which controls functions like eating and breathing, does not contract with age, and one can continue living without intellectual or emotional faculties.)
    Contraction of front and side parts—as cells die off—was observed in some subjects in their thirties, but it was still not evident in some sixty- and seventy-year-olds.
    Matsuzawa concluded from his tests that there is a simple remedy to the contraction normally associated with age—using the head.  The findings show in general terms that contraction of the brain begins sooner in people in the country than in the towns. Those least at risk, says Matsuzawa, are lawyers, followed by university professors and doctors. White collar workers doing routine work in government offices are, however, as likely to have shrinking brains as the farm worker, bus driver and shop assistant.    Matsuzawa’s findings show that thinking can prevent the brain from shrinking. Blood must circulate properly in the head to supply the fresh oxygen the brain cells need. “The best way to maintain good blood circulation is through using the brain,” he says, “Think hard and engage in conversation. Don’t rely on pocket calculators.”
    小题1:The team of doctors wanted to find out ________.
    why certain people age sooner than others  
    B. how to make people live longer
    C. the size of certain people’s brains       
    D. which people are most intelligent
    小题2:On what are their research findings based?
    A survey of farmers in northern Japan.       
    B. Tests performed on a thousand old people.
    C. The study of brain volumes of different people 
    D. The latest development of computer technology.
    小题3:The word “subjects” in Paragraph 5 means ________.
    something to be considered                 
    B. branches of knowledge studied
    C. persons chosen to be studied in an experiment  
    D. any member of a state except the supreme ruler.
    小题4:According to the passage, which people seem to age slower than the others?
    A．Lawyers.B．Farmers.
    C．Clerks.D．Shop assistants.

    Have you ever thought, “I wish I could take a year off and just travel around the word?” Well, three lucky American teenagers were able to do just that. The teens — two males and one female — got an all-expenses paid, yearlong hike to five continents.
    This trip didn’t include any five-star hotels or shopping funs. Eighteen-year-old Jamie Fiel from Keller, Texas, 17-year-old Arsen Ewing from Canyon, California, and 16-year-old Tyler Robinson from Lincoln, Massachusetts, didn’t expect fancy treatment. They signed up for the experience of a lifetime, which included hard work, often uncomfortable accommodations, and encounters with some of nature’s most dangerous animals and environments.
    Jamie, Arsen, and Tyler were among hundreds of high school kids nominated by their science teachers to take this trip. Earthwatch Institute sponsored this adventure. Each year, Earthwatch employs thousands of volunteers worldwide to help with scientific research projects.
    The group went all around the world to get a close look at the most pressing environmental issues of our time. Their assignments were as varied as their locations, and included measuring and attending pink flamingos in Kenya’s Great Rift Valley, and tracking giant sea turtles in Costa Rica.
    As they worked with the Earthwatch scientists, Jamie, Arsen, and Tyler began to understand that we are at a critical moment in the life of our planet. Time for change is running out. As the teens went from country to country and witnessed different environmental dangers and challenges, they understood that solutions to important environmental issues start with the power of one person’s actions. They realized that each of them can make a difference.
    小题1:These teenagers went on the journey around the world      .
    A．to experience the most serous environmental problems on the earth
    B．to bring the kindness of America to the other parts of the world
    C．to go on sightseeing around the world
    D．to call on more teenagers to join Earthwatch Institute
    小题2:What’s TRUE about their journey?
    A. They had to pay for their journey on their own expense.
    B, They often had to move from one hotel to another.
    C. They had to take great pains to collect environmental information.
    D. They received a warm welcome every time they arrived at a new place.
    小题3:It can be inferred that Earthwatch Institute could be          .
    A. an international university that takes in students from all over the world
    B. a TV station that makes programmes on the beautiful scenery of the earth
    C. a travel agency that organizes adventure trips specially for school children

    What do you use to get around town? A car? A bike? Your feet ? perhaps you should try a segway!
    The Segway is perfect for short journeys. It’s an electric vehicle that consists of a platform between two wheels, with a pole that connects the platform to the handlebars. To ride it , you step up onto the platform, and control the Segway by moving your body. Lean forwards to go faster, and back-wards to slow down.
    On older models, direction was controlled by a twist grip（扭转把手）on the left handlebar. This varies the speeds between the two motors, and a decrease in the speed of the left wheel would turn the Segway to the left . With newer models you simply lean to the left or right. Meanwhile, a gyroscope （陀螺仪）detects your movements and prevents the machine from falling over. The Segway has a maximum speed of 19 km per hour and a range of about 38 km. after that, you need to plug it and recharge the battery.
    Segways are used for a variety of purposes. People with mobility problems can now enjoy walks in the country with their friends and family. Some golfers see them as an alternative to the golf cart . And dog owners now have an easier way to take the dog to the park. A few police forces use Segways, too. They allow officers to move quickly while maintaining contact with the public. They’re also becoming a common sight on airport . However, the most popular use is in tourism , particularly for city tours . Visit any major tourist city in summer, sit outside a cafe for a while and there’s a good chance you’ll see a group of tourists passing on Segways.
    小题1:How do you turn to the left on a Segway of the new model?
    A．Lean to the leftB．Adjust the twist grip
    C．Press the left barD．Control the gyroscope
    小题2:How far can you travel on a Segway at most?
    A．Less than 19 kmB．About 19 km
    C．About 38 kmD．Over 45 km
    小题3:The Segway is most commonly used by       .
    A．familiesB．golfers
    C．policeD．tourists
    小题4:Which of the following correctly shows the order in which information about the Segway is provided?
    A．Introduction→Ways of application→ structure→Principle of operation
    B．Introduction→ Principle of operation→Structure →Ways of application
    C．Introduction → Structure → Principle of operation →ways of application
    D．Structure→ Introduction→Principle of operation→Ways of application

    Picture the scene: the battery on your mobile phone has run out． You can't make any calls for help and no one can contact you． You are all alone - well, not quite． Just reach into your pocket and take out a piece of sugar．Put it into the battery, wait a minute, and you're back on the phone．
    Thanks to a couple of American scientists, this situation could become real．Swadesh Chaudhuri and Derek Lovely have invented the"bacteria battery" - powered by bacteria that eats sugar and turns it into electricity．
    "This is a special organism," Lovely said．"You can harvest enough electricity to power a cell phone battery for about four days from a spoonful of sugar．"
    In the past, bacteria batteries have been expensive and not long-lasting． But this battery uses more efficient bacteria that can turn 80 percent of sugar into electrical energy． This is 30 percent more than similar batteries can manage．
    The bacteria battery could become as small as a household battery． It's also cheap and stable, as sugar can be taken from waste and crops．
    But the sugar to electricity process is slow: it could take weeks for the bacteria to digest a cup of sugar．And it produces "greenhouse" gases which pollute the environment．
    The scientists understand there is a lot more work to be done． "It is still young," said Lovely．"Where we are now is where solar power was 200r 30 years ago．"
    But he believes the battery could be used in scientific equipment at the bottom of the ocean．Other ideas include using sugar in the blood to run medical devices in the human body, and taking sugar from animal waste to provide energy to power homes in rural areas．
    小题1:This passage is mainly about_       ．
    A．how to change sugar into electricity
    B．a scientific invention of a new kind of bacteria battery
    C．a new way to reduce pollution caused by mobile phones
    D．a new kind of mobile phones and its future
    小题2:Which of the following is not the strong point of the newly-developed battery?
    A．Convenient．B．Stable．C．Inexpensive．D．Quick．
    小题3:The underlined sentence in the 7th paragraph actually means        ．
    A．the bacteria battery shares some similarities with solar energy
    B．scientists will continue their work until they find solar power
    C．there is much room for the improvement of the bacteria battery
    D．the bacteria battery will get popular in 20 0r 30 years
    小题4:According to the passage, who will find the bacteria battery less useful?
    A．Farmers．B．Divers．C．Doctors．D．Electricians．
