    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.

    小题1:C
    小题2:B
    小题3:D
    小题4:B
    小题5:A

    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 .
    小题1:When he was in China , Marco polo ___________ .
    A．discovered CaiLun invented paper
    B．learned to make paper
    C．saw many wonderful things
    D．told people about it
    小题2:About _______ tons of paper are thrown away every day in our city.
    A．1700B．2000C．2800D．48000
    小题3:Which of the following is NOT the way of saving paper ?
    A．To use both sides of every piece of paper
    B．To use the paper bags from shops more than once
    C．To use cotton handkerchiefs instead of paper ones
    D．To grow more trees
    小题4:Which of the following is NOT TRUE ?
    A．If we keep on wasting paper , we will have no paper to use
    B．The Chinese used paper money much earlier than the people in western countries
    C．About 48000 trees can be used to make 2800 tons of paper
    D．It is never too late to plant trees for paper .
    小题5:Which is the best title (标题)of the passage ?
    A．Saving PaperB．The history of Paper
    C．Cotton Handkerchiefs Back AgainD．CaiLun , the Great Inventor

    Some people believe that classes, teachers and school buildings will no longer be necessary in the near future because of the Internet and other new technology. Perhaps this will be true one day, but if the world has no schools, I can't imagine how our society will be. In fact, we should learn how to use new technology to make schools better. We should invent a new kind of school connected to libraries, museums, science centers, labs and even companies. Technological companies should create learning programs for schools. Scientists could give talks through the Internet. TV networks and local stations could develop programs about things students are studying in school. Labs could set up websites to show new technology, so students could see it on the Internet.
    Is this a dream? No. There have been many cities where this is beginning to happen. Here the whole city is connected to the Internet, and learning can take place at home, at school, and in the office. Businesses provide programs for the schools and the society. The schools provide computer labs for people without their own computers at home. Because everyone can go on the Internet, older people use it as much as younger ones, and everyone can visit faraway libraries and museums as easily as nearby ones. How will this new thing of school change the usual way of learning? It is a little early to be sure, but it is very exciting to think about it. Technology will change the way we learn; schools will change as well; and we will learn something from the Internet.
    小题1:Who thinks that students won’t have to go to school?
    A．Everyone.B．The writer.C．Some people.D．The teachers.
    小题2:What does “a new kind of school” mean in the passage?
    A．A school with many new computers.B．A school with many new students.
    C．A school with many new teachers.D．A school connected to the Internet.
    小题3:What the writer thinks is that____________.
    A．schools are still necessaryB．more schools should be built
    C．there should be fewer schoolsD．more computers are needed in schools
    小题4:Why do people think learning can take place at home, at school, and in the office?
    A．Because whole city is connected to the Internet.
    B．Because everyone can go on the Internet.
    C．Because getting online is very easy.
    D．Because Scientists could give talks through the Internet.
    小题5:What fact does the passage NOT provide?
    A．Technology will change our way of learning.
    B．If you are a student, you can set up websites to show new technology.
    C．The schools provide computer labs for those who have no personal computers.
    D．On the Internet, you can visit another city's libraries as easily as the people there.

    Garden building is considered an important part of Chinese culture. Some people say that if you have never walked through a Chinese garden, you cannot say that you have really visited China.
    Traditional Chinese gardens are located(位于)in North China in such places as Beihai Park, the Summer Palace, the Forbidden City. In larger imperial gardens, the main buildings are connected by an imaginary（虚构的） line in the middle of the garden on the north-south axis(轴). Other features (特征)of imperial gardens are colored-paintings, man-made hills and lakes.
    Most private gardens are found in the south, especially in cities south of the Yangtze River. Private gardens were mostly built at one side or at the back of the houses. Around the beautiful scene are small open areas with beautiful shaped-doors through which visitors can enjoy the sights. They are open on all sides and are often near the water so that the whole scene can be enjoyed. Suzhou, known as the home of gardens, displays the most and the best Chinese traditional private gardens. Different parts of it are examples of the garden style of the Song, Yuan, Ming and Qing Dynasties.
    The landscape garden contains a number of pleasant natural scenes and some fairy tales. The ancient Chinese used to call the garden landscape “Jing” , which means “scene” in English. Good examples include the ten West Lake Scenes in Hangzhou, the twenty-four slim West Lake in Yangzhou and the eight Daming Lake Scenes in Jinan.

    We all enjoy the beautiful show of colours as leaves change each autumn. But did you ever wonder how and why this happens?
    Leaves are nature’s food factories. Plants take water from the ground through their roots and take carbon dioxide (二氧化碳) from the air. Plants use sunlight to turn water and carbon dioxide into glucose (葡萄糖). Glucose is a kind of sugar, which plants use as food for energy and growing.
    The way plants turn water and carbon dioxide into sugar is called photosynthesis that means “ putting together with light”. A chemical called chlorophyll helps photosynthesis. It gives plants their green colour. As summer ends and autumn comes, the days get shorter and shorter, and trees “know” to begin getting ready for winter.
    During winter, there is not enough light or water for photosynthesis. Trees rest during this time and live on the food they store during the summer. They begin to shut down their food-making factories.
    As the green chlorophyll disappears from the leaves, we begin to see yellow and orange leaves. Small amounts of these colours have been in the leaves all along. We just can’t see them in the summer, because they are covered up by the green chlorophyll.
    The bright reds and purples we see in leaves are made mostly in autumn. In some trees, like maples (枫树), glucose is caught in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn turn this glucose into a red colour. The brown colour of trees like oaks (橡树) is made from waste left in the leaves.
    It is the mixture of all these things that makes the beautiful colours we enjoy during autumn.
    小题1:The word “chlorophyll” in the third paragraph means _______ in Chinese.
    A．叶绿素B．氧气C．胡萝卜素D．蛋白质
    小题2:The leaves of the trees in autumn turn yellow because of the short of _____.
    A．water and carbon dioxide
    B．glucose and energy
    C．sunlight and water
    D．sunlight and carbon dioxide
    小题3:The way that _______________________ is called Photosynthesis .
    A．plants change water and carbon dioxide into sugar
    B．plants turn water and carbon dioxide into sugar with the help of sunlight
    C．plants use glucose as food for energy and growing
    D．chlorophyll is a great help
    小题4:Which of the following is NOT true?
    A．When autumn and winter come, the days get shorter and shorter.
    B．During winter trees rest and live on the food they store during the summer.
    C．During winter small amounts of yellow and orange colours are kept in the leaves all the time.
    D．Trees begin to stop making food in summer.
    小题5:This passage tells us __________________.
    A．all the plants can grow well with the strong sunlight
    B．there are all kinds of plants on the earth
    C．all the colours of the leaves aren’t made from chlorophyll
    D．maples and oaks have the same reason as other trees for the change of colours
