    In the 13th century, the Italian traveler, Marco polo , traveled a long way to China , During his stay in China , he saw many wonderful things . One of the things he discovered was that the Chinese used paper money . In western countries , people did not use paper money until the 15th century . However , people in China began to use paper money in the 7th century .
    A Chinese man called CaiLun invented paper almost 2000 years ago. He made it from wood . He took the wood from trees and made it into paper . He then put these pieces of paper together and made them into a book .
    Now paper still comes from trees . We use a lot of paper every day ! If we keep on wasting so much paper , there will not be any trees on the earth . If there are no trees , there will be no paper . Every day , people throw away about 2800 tons (吨) of paper in our city . It takes 17 trees to make one ton of paper . This means that we are cutting nearly 48000 trees every day . Since it takes more than 10 years for a tree to grow , we must start using less paper now . If we don’t , we will not have enough time to grow more trees to take the place of those we use for paper .
    So how can we save paper ? We can use both sides of every piece of paper , especially when we are making notes .We can choose drinks in bottles instead of those in paper packets . We can also use cotton handkerchiefs (手帕) and not paper ones . When we go shopping , we can use fewer paper bags . If the shop assistant does give us a paper bag, we can save it and reuse it later .
    Everyone can help to save paper . If we all think carefully , we can help protect trees . But we should do it now , before it is too late .

    Who wants to carry a bulky bag to school? No children. Nobody wants one shoulder to be lower than the other, and paining(疼痛) too. In India, most of us would look at the reduction(减少) of textbooks as a way out. But in a country like America, there are always more choices. A company called Goreader has created a “school bag” which is the size of a laptop computer, weighing about 2.5kg. The Goreader has a colour screen and can “hold” all the textbooks that a student may need, says a report in “The Asian Age” newspaper.
    The company plans to work closely with the publishers of test books so that these books can be supplied on the Internet. All the students will have to download their textbooks. Making notes and marking important parts of a lesson can be done just as lots of students have done on their textbooks before.
    At present, the plan is being tested out in a university. Richard Katzmann, the owner of the company is having his creation tested at Chicago’s DePaul University, where he studied. Does that mean it is goodbye to the newspaper, and the smell of the black ink?
    小题1:What does the underlined word “bulky” in the first line mean?
    A．lightB．smallC．big and heavyD．old
    小题2:What would Indians do to solve this problem?
    A．They would reduce the textbooks.
    B．They would tell the parents to help students.
    C．They would tell the teachers to help students.
    D．They would take students to school by bus.
    小题3:The writer may think that Americans have a ______ way to solve the problem.
    A．more stupidB．worseC．betterD．quicker
    小题4:The Goreader may be a machine ________.
    A．that can work as a teacher
    B．that can be used as textbooks
    C．that can cheat(欺骗) students.
    D．that can hurt students
    小题5: When the new machine is used, it is possible that ________.
    A．students might study harder
    B．students might study at home
    C．students might not need teachers
    D．students might study without paper textbooks

    When you look up into the sky at night, have you ever felt that your eyes are playing tricks on (捉弄) you? It seems that the stars are moving all the time.
    Actually, there is nothing wrong with your eyes. This twinkling effect is called scintillation (交光). Scintillation happens because of air movements in the earth’s atmosphere (大气). Light is “bent (弯曲的)” when it travels through different parts of the earth’s atmosphere. As the air in the earth’s atmosphere is moving all the time, the light from the stars looks as if it is moving too.
    The same thing also happens to things on the ground. On a very hot and shiny day, if you look at the road, the image in the distance is not clear and things move slightly. You can also see the same effect if you drop a rock into water. The rock appears a little unclear under the moving water.
    This twinkling effect causes a lot of problems for astronomers (天文学家) since they cannot observe the stars clearly. A telescope (望远镜) was sent into space so that the air movements in the atmosphere could be avoided (避免). It took a long time to build the space telescope but finally in 1990, a huge space telescope called the Hubble Space Telescope was successfully sent into space. Since then, astronomers have many important observations that have helped people understand space better.

    A．rainy daysB．shiny days
    C．cloudy daysD．windy days
    小题3:What can you see when you drop a rock into the water?
    A．The rock gets broken.
    B．The rock becomes unclear.
    C．The water becomes much polluted.
    D．The water does not move anymore.
    小题4:The underlined word “observe” means “　　　　”.
    A．watchB．listenC．drawD．explain
    小题5:Why is scintillation a problem for astronomers?

    B．It makes the stars too dark to see.
    C．It makes astronomers feel too hot to work.
    D．Astronomers cannot observe the stars clearly.

    Look at the center circles of Diagram (图) A and Diagram B.  Which of the centre circles looks larger? 
    Take a first look and you probably think that the centre circle in Diagram A is smaller than that in Diagram B. In fact , they are exactly the same size.
    Then look at the picture on the right. What do you see? A vase ? Or two faces? Does the picture change quickly from one to the other again and again? Maybe or maybe not, but you can never see them at the same time. 
    "What's happening? Is something wrong with my eyes?" You may wonder at what you see. Don't worry. Here is how it goes:

It seems that our eyes are playing a joke on us. This often happens and we call it "Visual illusion" (视觉错误). 
    Movie makers often make use of illusions. They make the objects around actors much smaller or bigger than usual. This makes us believe that the actors are much larger or smaller than they usually are. The movies Jurassic Park and Honey I shrunk the kids just make use of illusions.

    According to some predictions, human beings will die out in 2012. Nearly all people think it’s impossible, but there are some more earthquakes in recent years.
    Animals can predict the weather or other natural events. It may sound strange, but farmers living in the countryside think so. For hundreds of years , they have observed animals.
    “Animals ’ behavior can be connected to future weather conditions or events.” They say. For example, if cows lie down, a rainstorm is coming. There are many traditional stories connecting animals and natural events. Many people think that these stories don’t have scientific evidence( 根据 ) at all. Scientists, however, are beginning to take another look at some of these ideas.
    A Japanese earthquake researcher named Kiyoshi Shimamura noticed an increase in dog bites a short time before earthquake hit. Then he did research on twelve public health centers in Kobe, Japan. These health centers treated people after the 1995 earthquake . He got some interesting information about the month before the big earthquake:  treatment for animals’ bites had increased . In fact, aggressive(侵略的)behavior in dogs, such as biting and barking loudly , jumped 60 percent.
    There are also other changes in animals’ behavior before the earthquake. For example, fish began swimming together in large groups , but only in the middle of the water and not near the edges. Birds flew away from their nests for many days, leaving their eggs unprotected . These animals’ behavior suggests that animals may be able to predict natural events better than people.
    小题1:What would cows behave before a rainstorm?
    A．RunningB．BitingC．Lying downD．Sleeping
    小题2:What do dogs begin to do just before an earthquake?
    A．They leave their homes. B．They hurt people.
    C．They lie down in grass.D．They stay together in large groups.
    小题3:Which of the following animals behave strangely before an earthquake according to this passage?
    A．FishB．CowsC．PigsD．All of the above.
    小题4:In Kiyoshi Shimamura’s investigation(调查)，before the big earthquake, treatment for animals’  bites had _________.
    A．disappearedB．increasedC．been the same as before.D．never changed.
    小题5:What is the main idea of the passage?
    A．Natural events and animals’ actions.
    B．What animals do during earthquakes
    C．Many earthquakes of Japan.
    D．Some stories about animals.
