    Sports shoes that work out whether their owner has done enough exercise to promise time in front of the television have been devised in the UK.
    The shoes- named Square Eyes- contain an electronic pressure sensor and a tiny computer chip to record how many steps the wearer has taken in a day. A wireless transmitter (发射器) passes the information to a receiver connected to a television, and this decides how much evening viewing time the wearer deserves(应得), based on the day's efforts.
    The design was inspired by a desire to fight against the rapidly ballooning waistlines among British teenagers, says Gillian Swan, who developed Square Eyes as a final year design project at Brunel University in London, UK. "We looked at current issues and childhood overweight really stood out," she says. "And I wanted to tackle that with my design."
    Once a child has used up their daily allowance gained through exercise, the television automatically (自动地) switches off. And further time in front of the TV can only be earned through more steps. Swan calculated how exercise should translate to television time using the recommended daily amounts of both. Health experts suggest that a child take 12,000 steps each day and watch no more than two hours of television. So, every 100 steps recorded by the Square Eyes shoes equals exactly one minute of TV time.
    Existing pedometers(计步器) normally clip onto a belt or slip into a pocket and keep count of steps by measuring sudden movement. Swan says these can be easily tricked into recording steps through shaking. But her shoe has been built to be harder for lazy teenagers to cheat. "It is possible, but it would be a lot of effort," she says. "That was one of my main design considerations."
    小题1:According to Swan, the purpose of her design project is to _____.
    A．keep a record of the steps of the wearer.
    B．deal with overweight among teenagers.
    C．enable children to resist (抵制) the attraction of TV.
    D．prevent children from being tricked by TV programs.
    小题2:Which of the following is true of Square Eyes shoes?
    A．They control a child's evening TV viewing time.
    B．They determine a child's daily pocket money.
    C．They have raised the hot issue of overweight.
    D．They contain information of the receiver.
    小题3:Compared with other similar products, the new design ___.
    A．sends teenagers' health data(数据) to the receiver.
    B．counts the wearer's steps through shaking.
    C．records the sudden movement of the wearer.
    D．make it difficult for lazy teenagers to cheat
    小题4:Which of the following would be the best title for the text?
    A．Smart Shoes Stop Childhood Overweight
    B．Smart Shoes Guarantee More Exercise
    C．Smart Shoes Measure Time of Exercise
    D．Smart Shoes Decide on Television Time

    小题1:B
    小题2:A
    小题3:D
    小题4:D

    Once my mother told me a story that in Africa, when an antelope (羚羊) wakes up every morning, the first thing it thinks about is, “I must be 36 to run faster than the fastest lion, or I will be killed.” 37 , a lion wakes from his dream. The first thing the lion thinks about is, “I must be able to catch the 38 antelope, or I will starve to 39 .” So almost simultaneously(同时地), the antelope and the lion get up and start running toward the 40 sun.
    This is 41 : full of chances and challenges. Whether you are an antelope or a lion, you must go 42 when the sun rises. For students, it is just the same.

    I was still not sure what competition 51 meant. One day, I was 52_in an English-speaking competition. When I went to the stage, I saw other students looking at me kindly. Suddenly I 53 what competition was. It is not as cruel as my teacher and parents told me. In fact, competition is the 54 : it is kind and necessary.

    Living in a modern society with more and more out-of-date but still useful computers, many people have to face such a troubling problem: How to deal with those old computers? Some old ones are put away in homes. Many more are just thrown out with the rubbish.
    Don’t worry! Some companies are coming up with new ways to cut the number of old computers. Sony, Dell, Hewlett-Packard and other companies now agree to take back some old computers.
    In some countries, there are laws about what to do with old computers. By law, computer companies will have to pay for collecting and recycling their used products. And 70% of computer waste must be recycled. The idea behind the laws is that computer companies themselves should pay the cost. That will encourage them to make computers that are easier and cheaper to repair and upgrade（升级）.
    While many people are throwing away good computers, others cannot afford them at all. Hundreds of organizations（组织）are working to solve this problem. They collect and repair old computers before sending them to schools, charities（慈善团体）and people who need them. In this way, we can turn one person's rubbish into someone else's useful things-and cut down on waste.
    小题1:What do many people do with old computers?
    A．They sell them to others.
    B．They try to repair them.
    C．They give them to others.
    D．They stop using them
    小题2:According to laws in some countries mentioned in the passage, computer companies must_____.
    A．recycle most of their products
    B．make their computers cheaper
    C．repair and upgrade old computers
    D．collect all their used products
    小题3:The last paragraph mainly tells us that hundreds of organizations are working to _________.
    A．help the computer companies to collect old ones
    B．repair old ones and send them to whoever needs them.
    C．advise people not to throw away good computers.
    D．encourage people to turn rubbish into useful things.
    小题4:What is the main idea of this passage?
    A．How to repair old computers.
    B．Avoid producing too many computers.
    C．Encourage to recycle old computers.
    D．How to turn rubbish into useful things

    Nothing succeeds like confidence. When you are truly confident, it radiates (辐射) from you like sunlight, and attracts success to you like a magnet (磁铁). Besides, those who are self-confident can in turn inspire (encourage) confidence in others: their audience, their peers, their bosses, their customers, and their friends. And gaining the confidence of others is one of the key ways in which a self-confident person finds success.
    So how can we build a sense of self-confidence and prepare ourselves on the way to success?
    First, do what you believe to be right, even if others mock or criticize you for it. Believe in yourself and believe that you can do it in any situations, because if you believe you can, then you really will. The belief keeps you searching for answers, which means that pretty soon you will get them.
    Second, govern your behavior based on what other people think. What’s more important, be willing to take risks and go the extra miles to achieve better results, in which case mistakes can not be avoided. Always be ready to admit your mistakes, and learn from them. Next, work hard to settle the problems in order to cover up your mistakes before anyone notices. Building self-confidence is readily achievable, as long as you have the focus and determination to carry things through. And what’s even better is that the things you’ll do to build self-confidence will also build success -- after all, your confidence will come from real, solid achievement. No one can take this away from you!
    As you sow, so will you reap. With your perseverance (毅力) and improvement, you are getting closer to success. At this stage, wait for others to give congratulations and compliments on your achievements. “Thanks, I really worked hard on it. I’m pleased you recognize my efforts.” The congratulations and compliments from others will promote you to gain further success.
    Self-confidence is extremely important in almost every aspect of our lives, and it is no wonder that so many people struggle to find it. Self-confidence really can be learned and built on. Besides, whether you’re working on your own self-confidence or building the confidence of people around you, it’s well worth the effort!
    小题1:Those who are truly confident _______.
    A．succeed without effort and hard work
    B．encourage people around to become confident
    C．appear more attractive and thus become successful
    D．gain the confidence of others and feel successful
    小题2:The underlined word “mock” (Paragraph 2) is closest in meaning to _______.
    A．praiseB．imitate (模仿)C．punishD．laugh at
    小题3:When others congratulate us on our achievements, we are supposed to _______.
    A．praise them in return
    B．gain further improvement
    C．politely accept the compliments
    D．expect them to congratulate you again
    小题4:Which of the following proverbs (sayings) best goes with Paragraph 4?
    A．Look before your leap.
    B．It is no use crying over spilt milk.
    C．Genius is 1% inspiration and 99% perspiration.
    D．Learn from past mistakes and avoid future ones.
    小题5:The purpose of the text is to _______.
    A．tell people how to become successful
    B．convince people to do what they believe to be right
    C．encourage people to build confidence and achieve success
    D．criticize people who lack confidence and thus fail in their career

    The common cold is the world's most widespread illness, which is a serious infection that man receives.
    The most widespread mistake of all is that colds are caused by cold. They are not. They are caused by viruses passing on from person to person. You catch a cold by touching directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in separate Arctic (北极的)areas, explorers have reported being free from colds until touching again with infected people from the outside world by way of packages and mail dropped from airplanes.
    During the First World War, soldiers who spent long periods in the trenches, cold and wet, seldom caught colds.
    In the Second World War, prisoners at Auschwitz concentration camp, bare and starved, were astonished to find that they seldom had colds.
    At the Common Cold Research Unit in England, volunteers took part in experiments in which they gave themselves to the discomforts of being cold and wet for a long time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in a room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.
    If then, cold and wet have nothing to do with catching colds, why are they more frequent in winter? Despite the most hard research, no one has yet found out the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and that makes it easier for cold viruses to be passed on.
    No one has yet found a cure for the cold. There are drugs and pain-killers such as aspirin, but all that they do is to reduce the symptoms.
    小题1:The writer thinks the cause of catching cold is due to_______.
    A．touching anyone directly
    B．touching anyone indirectly
    C．cold weather
    D．getting viruses from person to person
    小题2:Arctic explorers may catch colds when___.
    A．they are working in the separate Arctic areas
    B．they are writing reports in terribly cold weather
    C．they are free from work in the isolated Arctic regions
    D．they are coming into touch again with the outside world
    小题3:Volunteers taking part in the experiments in the Common Cold Research Unit___.
    A．suffered a lotB．never caught colds
    C．often caught coldsD．became very strong
    小题4:The passage mainly discusses___.
    A．the experiments on the common cold
    B．the mistake about the common cold
    C．the reason and the way people catch colds
    D．the continued spread of common colds

    Doctors say anger can be an extremely damaging emotion, unless you learn how to deal with it. They warn that anger can lead to heart disease, stomach problems, headaches, emotional problems and possibly cancer.
    ___1___ Some people express anger openly in a calm reasonable way. Others burst with anger, and scream and yell. But other people keep their anger inside. They can not or will not express it. This is called repressing anger.
    For years many doctors thought that repressing anger was more dangerous to a person’s health than expressing it. They said that when a person is angry, the brain releases the same hormones (荷尔蒙). They speed the heart rate, raise blood pressure, or sugar into the blood, etc. ___2___
    Some doctors say that both repressing and expressing anger can be dangerous. They believe that those who express anger violently may be more likely to develop heart disease, and they believe that those who keep anger inside may face a greater danger of high blood pressure.
    ___3___ They say the first step is to admit that you are angry and to recognize the real cause of the anger, then decide if the cause is serious enough to get angry about. If it is, they say, “___4___ Wait until your anger has cooled down and you are able to express yourself calmly and reasonably.”
    Doctors say that a good way to deal with anger is to find humor in the situation that has made you angry. ___5___
    A．In general the person feels excited and ready to act.
    B．They said that laughter is much healthier than anger.
    C．Expressing anger violently is more harmful than repressing it.
    D．Do not express your anger while angry.

    You never see them, but they're with you every time you fly. They record where you are going, how fast you're traveling and whether everything on your airplane is functioning normally. Their ability to withstand almost any disaster makes them seem like something out of a comic book. They're known as the black box.
    When planes fall from the sky, as a Yemeni airliner did on its way to Comoros Islands in the India ocean June 30, 2009, the black box is the best bet for identifying what went wrong. So when a French submarine (潜水艇) detected the device's homing signal five days later, the discovery marked a huge step toward determining the cause of a tragedy in which 152 passengers were killed.
    In 1958, Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first mode for a black box, which became a requirement on all U.S. commercial flights by 1960. Early models often failed to withstand crashes, however, so in 1965 the device was completely redesigned and moved to the rear of the plane – the area least subject to（易遭受）impact – from its original position in the landing wells (起落架舱). The same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to aid visibility.
    Modern airplanes have two black boxes: a voice recorder, which tracks pilots' conversations, and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help investigators reconstruct the aircraft's final moments. Placed in an insulated (隔绝的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can withstand massive force and temperatures up to 2,000℉. When submerged, they're also able to emit signals from depths of 20,000 ft.
    Experts believe the boxes from Air France Flight 447, which crashed near Brazil on June 1, 2009, are in water nearly that deep, but statistics say they're still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane's black boxes were never recovered.
    小题1:What information could be found from the black box on the Yemeni airliner?
    A．Data for analyzing the cause of the crash.
    B．The total number of passengers on board.
    C．The scene of the crash and extent of the damage.
    D．Homing signals sent by the pilot before the crash.
    小题2:Why was the black box redesigned in 1965?
    A．New materials became available by that time.
    B．Too much space was needed for its installation.
    C．The early models often got damaged in the crash.
    D．The early models didn't provide the needed data.
    小题3:Why did the Federal Aviation Authority require the black boxes be painted orange or yellow?
    A．To distinguish them from the colour of the plane.
    B．To caution people to handle them with care.
    C．To make them easily identifiable.
    D．To obey international standards
    小题4:What do we know about the black boxes from Air France Flight 447?
    A．There is still a good chance of their being recovered.
    B．There is an urgent need for them to be reconstructed.
    C．They have stopped sending homing signals.
    D．They were destroyed somewhere near Brazil.

    阅读下面的短文，并根据短文后的要求答题(请注意问题后的字数要求)。
    [1]Everyone makes mistakes. How do you react when a family member, friend, or a classmate makes a mistake? Some of us may shout out , complain, or punish. Unfortunately, these reactions to mistakes sometimes greatly hurt both sides. In fact, there is a better way to deal with a mistake.
    [2]Reframe（重组） "MISTAKE": Change "MISTAKE" into "MIS-TAKE." Doesn't that have a different feeling? Therefore, a mistake is not so bad as expected. We can learn from it and it is likely to lead to success in the end.
    [3]Use mistakes as an opportunity for learning. Most of us want to hide our mistakes, but we may be more willing to share our "MIS-TAKES" and let others learn from them. Either an individual or a family can benefit by openly recognizing and correcting mistakes, rather than pretending that they didn't happen. In fact, a mistake, if corrected quickly and in a creative way, can become ___________for learning.
    [4]Think of mistakes as opportunities to prove yourself. A mistake becomes an opportunity to create a close friend or customer. For example, in business, studies show that one of the things all customers want is recovery when the organization has made a mistake. They want us to apologize sincerely. With creative thinking, we can make them satisfied with the way we deal with a mistake.
    [5] We have learned to allow people around us to make mistakes. Now give them “protection” when they make a mistake. If you give people both permission and protection, you will get along well with them. Show them how they can turn a mistake into learning something about themselves so they don’t make the same mistake again.
    小题1:What is the passage mainly about? (no more than 10 words)
    ___________________________________________________________               _____                                              
    小题2:What does the underlined word “it” in Paragraph 2 probably refer to? (no more than 3 words)

    小题3:Fill in the blank in Paragraph 3 with proper words.(no more than 4 words)

    小题4:Complete the following statement with proper words.(no more than 3 words)
    If we think creatively, we are able to make people feel pleased with the way in which a mistake is_________________.
