    How can you find out what is going on inside a person’s body without opening the patient’s body up? Regular X rays can show a lot. CAT scans can show even more. They can give a complete view of body organs.
    What is a CAT scan? CAT stands for a kind of machine. It is a special X-ray machine that gets a 360-degree picture of a small area of a patient’s body.
    Doctors use X rays to study and determine diseases and injuries within the body, X rays can find a foreign object inside the body or take pictures of some inside organs to be X-rayed.
    A CAT scanner, however, uses a group of X rays to give a cross-sectional（横截面）view of a specific part of the body. A fine group of X rays is scanned across the body and around the patient from many different directions. A computer studies the information from each direction and produces a clear cross-sectional picture on a screen. This picture is then photographed for later use. Several cross sections, taken one after another, can give clear “photos” of the entire body or of any body organs. The latest CAT scanners can even give clear pictures of active, moving organs, just as a fast-action camera can “stop the action”, giving clear pictures of what appears unclear to the eye. And because of the 360-degree pictures, CAT scans show clear and complete views of organs in a manner that was once only shown during operation or examination of a dead patient.
    Frequent appearance before X rays can cause skin burns, cancer or other damage to the body. Yet CAT scans actually don’t cause the patient to more radiation than regular X rays do. CAT scans can also be done without getting something harmful into the patient, so they are less risky than regular X rays.
    CAT scans provide exact, detailed information. They can quickly find such a thing as bleeding inside the brain. They are helping to save lives.
    小题1:What is NOT true of a CAT scan?
    A．It is safer than regular X rays.
    B．It makes use of computer techniques.
    C．It can stop the action of an organ for a short time.
    D．It gives clear pictures of active, moving body parts.
    小题2:The underlined words “a foreign object”（Para 3）most probably refer to     .
    A．a badly injured part inside the body
    B．a new thing that is unknown to the doctor
    C．a strange organ that has grown in the body
    D．an object that gets inside the body by chance
    小题3:What is the special use of the latest CAT scanners?
    A．It provides clear photos of moving organs.
    B．It can take 3-dimension（三维）pictures of inside organs.
    C．It won’t cause serious skin burns, cancer or other damage to the body.
    D．It helps to find out what is going on inside a person’s body without opening it up.

    You never see him, 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 back of the plane – the area least subject to 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 resist 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 does the author say about the black box?
    A．It ensures the normal functioning of an airplane.
    B．The idea for its design comes from a comic book.
    C．Its ability to resist disasters is incredible.
    D．It is an indispensable device on an airplane.
    小题2: 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3: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4: 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 conform to international standards.
    小题5: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.

    The famous director of a big and expensive movie planned to film a beautiful sunset over the ocean, so that the audience could see his hero and heroine in front of it at the end of the film as they said goodbye to each other for ever. He sent camera team out one evening to film the sunset for him.
    The next morning he said to the men, “Have you provided me with that sunset?”
    “No, Sir,” the men answered.
    The director was angry.  “Why not?”  he asked.
    “Well,” one of the men answered, “we are on the east coast here, and the sun sets in the west. We can get you a sunrise over the sea, if necessary, but not a sunset.”
    “But I want a sunset!” the director shouted. “Go to the airport, take the next flight to the west coast, and get one.”
    But then a young secretary had an idea. “Why don’t you photograph a sunrise,” she suggested, “and then play it backwards, Then it’ll look like a sunset.” “That’s a very good idea!” the director said. Then he turned to the camera team and said, “Tomorrow morning I want you to get me a beautiful sunrise over the sea.”
    The camera team went out early the next morning and filmed a bright sunrise over the beach in the middle of a beautiful bay. Then at nine o’clock they took it to the director. “Here it is, Sir,” they said, and give it to him. He was very pleased.
    They all went into the studio. “All right,” the director explained, “now our hero and heroine are going to say goodbye. Run the film backwards so that we can see the sunset behind them.”
    The “sunset” began, but after a quarter of a minute, the director suddenly put his face in his hands and shouted to the camera team to stop. The birds in the film were flying backwards away from the beach.
    小题1:One evening, the director sent his camera team out ______.

    THIS was the year the Earth struck back.
    Earthquakes, heat waves, floods, volcanoes, super typhoons, snow storms, landslides and droughts killed at least a quarter of a million people in 2010 – the deadliest year in more than a generation. More people were killed worldwide by natural disasters this year than have been killed in terrorism attacks in the past 40 years combined.
    "It just seemed like it was back-to-back and it came in waves," said Craig Fugate, who heads the U.S. Federal Emergency Management Agency. It handled a record number of disasters in 2010.
    And we have ourselves to blame most of the time, scientists and disaster experts say.
    Even though many catastrophes have the ring of random chance, the hand of man made this a particularly deadly, costly, extreme and weird（古怪的） year for everything from wild weather to earthquakes.
    Poor construction and development practices conspire to make earthquakes more deadly than they need be. More people live in poverty in vulnerable（脆弱的） buildings in crowded cities. That means that when the ground shakes, the river breaches, or the tropical cyclone hits, more people die.
    Disasters from the Earth, such as earthquakes and volcanoes "are pretty much constant," said Andreas Schraft, vice president of catastrophic perils for the Geneva-based insurance giant Swiss Re. "All the change that's made is man-made."
    The January earthquake that killed well more than 220,000 people in Haiti is a perfect example. Port-au-Prince has nearly three times as many people - many of them living in poverty - and more poorly built shanties than it did 25 years ago. So had the same quake hit in 1985 instead of 2010, total deaths would have probably been in the 80,000 range, said Richard Olson, director of disaster risk reduction at Florida International University.
    In February, an earthquake that was more than 500 times stronger than the one that struck Haiti hit an area of Chile that was less populated, better constructed, and not as poor. Chile's bigger quake caused fewer than 1,000 deaths.
    Climate scientists say Earth's climate also is changing, bringing extreme weather, such as heat waves and flooding.
    In the summer, one weather system caused oppressive heat in Russia, while farther south it caused flooding in Pakistan that inundated 161,200 square kilometers, about the size of Wisconsin. That single heat-and-storm system killed almost 17,000 people, more people than all the worldwide airplane crashes in the past 15 years.
    Scientists have calculated that the killer Russian heat wave—setting a national record of 43.9℃—would happen once every 100,000 years without global warming.
    小题1:What is responsible for the most human deaths in 2010?
    A．Natrual disasters.B．Terrorist attacks.
    C．Poor buildings.D．Too rapid developrnent.
    小题2:According to Andreas Schraft,             .
    A．earthquakes are happening more often because of human beings
    B．earthquakes are causing more damage because of human beings
    C．stronger houses should be built to limit storm damage
    D．Port—au—Prince is now overpopulated
    小题3:The main point of the article is to           
    A．list the natural disasters that occurred in 2010
    B．give the details of some natural disasters of 2010
    C．warn that more natural disasters are to strike
    D．blame humanity for not helping those affected by the disasters

    Take a look at the following list of numbers: 4, 8, 5, 3, 7, 9, 6. Read them loud. Now look away and spend 20 seconds memorizing them in order before saying them out loud again. If you speak English, you have about a 50% chance of remembering those perfectly. If you are Chinese, though, you’re almost certain to get it right every time. Why is that? Because we most easily memorize whatever we can say or read within a two-second period. And unlike English, the Chinese language allows them to fit all those seven numbers into two seconds.
    That example comes from Stanislas Dahaene’s book The Number Sense. As Dahaene explains: Chinese number words are remarkably brief. Most of them can be spoken out in less than one-quarter of a second (for instance, 4 is “si” and 7 “qi”). Their English pronunciations are longer. The memory gap between English and Chinese apparently is entirely due to this difference in length.
    It turns out that there is also a big difference in how number-naming systems in Western and Asian languages are constructed. In English, we say fourteen, sixteen, seventeen, eighteen and nineteen, so one might expect that we would also say oneteen, twoteen, threeteen, and fiveteen. But we don’t. We use a different form: eleven, twelve, thirteen and fifteen. For numbers above 20, we put the “decade” first and the unit number second (twenty-one, twenty-two), while for the teens, we do it the other way around (fourteen, seventeen, eighteen). The number system in English is highly irregular. Not so in China, Japan, and Korea. They have a logical counting system. Eleven is ten-one. Twelve is ten-two. Twenty-four is two-tens-four and so on.
    That difference means that Asian children learn to count much faster than American children. Four-year-old Chinese children can count, on average, to 40. American children at that age can count only to 15. By the age of five, in other words, American children are already a year behind their Asian friends in the most fundamental of math skills.
    The regularity of their number system also means that Asian children can perform basic functions, such as addition, far more easily. Ask an English-speaking seven-year-old to add thirty-seven plus twenty-two in her head, and she has to change the words to numbers (37+22). Only then can she do the math: 2 plus 7 is 9 and 30 and 20 is 50, which makes 59. Ask an Asian child to add three-tens-seven and two-tens-two, and then the necessary equation(等式) is right there, in the sentence. No number translation is necessary: it’s five-tens-nine.
    When it comes to math, in other words, Asians have a built-in advantage. For years, students from China, South Korea, and Japan --- outperformed their Western classmates at mathematics, and the typical assumption is that it has something to do with a kind of Asian talent for math. The differences between the number systems in the East and the West suggest something very different --- that being good at math may also be rooted in a group’s culture.
    小题1:What does the passage mainly talk about?
    A．The Asian number-naming system helps grasp advanced math skills better.
    B．Western culture fail to provide their children with adequate number knowledge.
    C．Children in Western countries have to learn by heart the learning things.
    D．Asian children’s advantage in math may be sourced from their culture.
    小题2:What makes a Chinese easier to remember a list of numbers than an American?
    A．Their understanding of numbers.
    B．Their mother tongue.
    C．Their math education.
    D．Their different IQ.
    小题3:Asian children can reach answers in basic math functions more quickly because ____________.
    A．they pronounce the numbers in a shorter period
    B．they practice math from an early age
    C．English speaking children translate language into numbers first
    D．American children can only count to 15 at the age of four

    The Touchstone
    When the great library of Alexandria burned, the story goes, one book was saved. But it was not a valuable book; and so a poor man, who could read a little, bought it for very little money.
    The book wasn’t very interesting, but between its pages there was something very interesting indeed. It was a thin strip of vellum on which was written the secret of the “Touchstone”! The touchstone was a small pebble that could turn any common metal into pure gold.
    The writing explained that it was lying among thousands and thousands of other pebbles that looked exactly like it. But the secret was this: The real stone would feel warm, while ordinary pebbles are cold.
    So the man sold his few belongings, bought some simple supplies, camped on the seashore, and began testing pebbles. He knew that if he picked up ordinary pebbles and threw them down again because they were cold, he might pick up the same pebble hundreds of times. So, when he felt one that was cold, he threw it into the sea. He spent a whole day doing this but none of them was the touchstone. Yet he went on and on this way. Pick up a pebble. Cold - throw it into the sea. Pick up another. Throw it into the sea. Pick up another. Throw it into the sea.
    The days stretched into weeks and the weeks into months. One day, however, about mid-afternoon, he picked up a pebble and it was warm. He threw it into the sea before he realized what he had done. He had formed such a strong habit of throwing each pebble into the sea that when the one he wanted came along he still threw it away.
    So it is with opportunity. Unless we are careful, it’s easy to fail to recognize an opportunity when it is in hand, and it’s just as easy to throw it away.
    小题1:The man bought the book because _____________.
    A．he wanted to read itB．it was very interesting
    C．there was a secret in the book D．he wanted to find the touchstone
    小题2:We can learn from the passage that the touchstone is _________.
    A．pureB．coldC．magicD．big
    小题3:Why did the man throw the pebbles into the sea?
    A．Because he didn’t want to get the same pebbles.
    B．Because he didn’t want others to pick them up.
    C．Because he didn’t like their ordinary looks.
    D．Because he didn’t like the cold feelings.
    小题4:What does the author want to tell us in the passage?
    A．We should offer opportunities in our life.
    B．We should seek for opportunities in the world.
    C．We may seize opportunities when we are watchful.
    D．We may discover opportunities when forming habits.

    The holiday's upon us. Finally, after months of study, you have some time to yourself. so, why not read a book? Well, some people will say, "Why bother with books? We have the Internet and other media that offer a lot more colorful entertainment. Books are history!" But don't be fooled. There's still a lot to be said for reading.
    One clear reason is that a well-chosen book is a wonderful source of vocabulary, so long as you have a good dictionary, of course. Believe me, it's far easier to get new English words and phrases from a book or article than it is from the TV or the Internet.
    But an even more important point is that books give you something that modern media simply can not. The average webpage is picture-heavy and the text is often designed to make it as easy to read as possible. While "easy" may be attractive, unfortunately it's little use for many long-term development of reading skills and the general language level. For that, there's still no substitute (替代品）of a book.
    But perhaps the best single reason is that simply choosing what you read and doing it independently means that it's something you do by yourself. You can choose what you want to read. It's hard work, but something down the line, you will find that what once seemed like a duty is now a pleasure. We asked three bookworms -- an English teacher, a book editor and a film critic - to pick some favorite reads for you.
    小题1: How many reasons for reading a book does the author mention in the passage?
    A．OneB．TwoC．ThreeD．Four
    小题2: According to this passage, we basically need a ______ in reading.
    A．computerB．dictionaryC．notebookD．pencil
    小题3:In the author's opinion, reading on the Internet may ________
    A．develop long-term reading skillsB．improve the general language ability
    C．not take the place of reading booksD．be an effective way of reading
    小题4: The passage is written mainly to ____________.
    A．share the pleasure of reading booksB．advise readers to read books
    C．stress the importance of reading online.D．help readers to choose good books.
