    Do you know why different animals or pests (昆虫) have their special colors? Colors in them seem to be used mainly to protect themselves.
    　　Some birds like eating locusts (蝗虫), but birds cannot easily catch them. Why? It is because locusts change their colors together with the change of the colors of crops(庄稼). When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color as crops have. Some other pests with different colors from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night.
    If you study the animal life, you’ll find the main use of coloring is to protect themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters (猎人). This is because they have the colors much like the trees.
    Have you ever noticed an even stranger act? A kind of fish in the sea can send out a kind of very black liquid (液体)when it faces danger. While the liquid spreads over (散开), its enemies (敌人)cannot find it. And it immediately swims away. So it has lived up to now though it is not strong at all.
    36. From the passage we learn that locusts________.
    A. are small animals                  B. are easily found by birds
    C. are dangerous to their enemies    D. change their colors to protect themselves
    37. How can pests with different colors from plants keep out of danger?
    A. They run away quickly.         
    B. They have the colors much like their enemies.
    C. They hide themselves by day and appear at night.      
    D. They have to move quietly.
    38. Bears and lions can keep safe because _________.
    A. they have the colors much like the trees     B. they move quietly
    C. they like brown and gray colors            D. they live in forests
    39. Why can the kind of fish live up to now?
    A. Because it is very and strong.    
    B. Because the liquid it sends out can help it escape from its enemies.
    C. Because the liquid it sends out can kill its enemies.
    D. Because it swims faster than any other fish.
    40. Which is the best title for this passage?
    A. The Change of Colors for Animals and Pests　 　
    B. Colors of Different Animals and Pests

    阅读下列短文, 从每题所给的选项（A、B、C和D）中，选出最佳选项，并在答题卷上将该项涂黑。
    B 
    　Two experts did some experiments on two groups of people — one who tended to sleep less than the
    people around them and the other group more.
    According to their report that the “short sleepers” had been more or less average in their sleep needs until the men were in their teens. But at about age 15 or so, the men automatically began to cut down their nightly sleep time because of pressures from school, work, and other activities. These men tended to view their nightly periods of unconsciousness as bothersome interruptions in their daily routines.
    　　 In general, these “short sleepers” appeared with ambition, active, energetic, cheerful, and conformist (不动摇) in their opinions, and very sure about their career choices. They often held several jobs at once, or even worked full time while going to school. And many of them had a strong urge to appear “acceptable” or “outstanding” to their friends and associates.
    　　When asked to recall their dreams, the “short sleepers” did poorly. More than this, they seemed to prefer not remembering them. In similar fashion, their usual way of dealing with psychological problems was to deny that the problem existed, and then to keep busy in the hope that the trouble would go away.
    　　The experts also stated that those “long sleepers” were quite different indeed. They reported that those men had been lengthy sleeps since childhood. They seemed to enjoy their sleep, protected it, and were a bit concerned when they were occasionally deprived of their desired 9 hours of nightly bed rest. They tended to recall their dreams much better than the “short sleepers did.
    　　Many of the “long sleepers” were shy, anxious, introverted (内向), inhibited (压抑), passive, mildly depressed, and unsure of themselves (particularly in social situations). Several openly express it that being asleep was a good escape from their daily problems.
    All in all, proper time of sleeping should be admired, not too long, neither too short.
    小题1:According to the report, ______.
    A．many “short sleepers” need less sleep just by nature
    B．many “short sleepers” are obliged to reduce sleep time by work
    C．long sleepers sleep a longer period of time during the day
    D．many “long sleepers” formed sleeping habit during childhood
    小题2: Many “short sleepers” are likely to hold the view that ______.
    A．sleep is a very efficient escape from the reality
    B．sleep is just an item which should be denied by them
    C．sleep might be a disturbing thing for their daily business
    D．sleep is the best way to deal with psychological troubles
    小题3: It is stated in the forth paragraph that “short sleepers” ______.
    A．are ideally energetic under the pressures of life
    B．often ignore the ill effect of not enough sleep
    C．do not know how to relax themselves properly
    D．are more unlikely to run into mental problems
    小题4:Which of the following is nearest to the meaning of “… were a bit concerned” in the fifth Para?
    A．appeared troubled B．became energetic
    C．felt dissatisfied D．were much depressed
    小题5:Which of the following is NOT correct according to the passage?
    A．If one sleeps improperly, his performance suffers and his memory is weakened
    B．The sleep patterns of short sleepers are the same as those shown by “long sleepers”
    C．Long and short sleepers differ in their attitudes towards sleep
    D．Short sleepers may have been better off if they have more rest

    In American schools there is something called Home-coming Day. Many high schools and colleges with a football team have a homecoming game.

      Environmental protection is frequently talked about nowadays. The authorities are doing their best to arise the public awareness of the vital importance of the environmental protection. This issue is, indeed, worth following up.
    Environmental protection is closely related not only to our personal life, but also to the entire human race and the world’s further development. For one thing, the environment, in a narrow sense, determines the quality of our individual life. The air we breathe, the water we drink, the food we eat, etc. , all come directly from the environment. If they continue to be contaminated, we may have neither clean water, nor healthy food. For another thing, in a broader sense, the environment plays a decisive role in fate of mankind. As is known to all, the earth, up to now, is human being’s only dwelling place. We can expect that some day we will live on another planet, but I doubt that this day will come earlier than the day when the earth becomes a globe of waste, if we keep damaging the environment. Finally, the environment is essential to the further development of the world. Extensive industrialization, which has brought about all the convenience and facilities we enjoy today, has been depending on the comprehensive exploitation of the earth’s natural resources found in the environment. If we do not protect the environment properly, further development cannot be guaranteed. In a word, to protect the environment is an urgent task.
    Nevertheless, environmental protection is indeed a demanding task. Many people are still, either unconscious of the urgency of the task or deliberately damaging the environment for the interests of their own. Hence, we should adopt severe measures to prohibit people from doing more harms to the environment. Meanwhile, we need to make the gravity of the present situation known to all. In other words, punishment and instruction should be equally emphasized. Only in this way can we look forward to a cleaner and greener world.
    小题1:.
    . What does the underlined word contaminated（in paragraph 2）probably refer to?
    A．pollutedB．protectedC．wastedD．guaranteed
    小题2:.
    The author’s purpose in writing the passage is to ________.
    A．stress the importance of protecting environment
    B．enjoy beautiful environment happily
    C．try to develop our industrialization fast
    D．take severe measures to the environmental destroyers
    小题3:.
    . From the passage we can know that ________.
    A．environmental protection is indeed a demanding task to our government
    B．not all the people in the world realize the urgency of the task
    C．only a few people are damaging the environment on purpose
    D．some day we will live on another planet before the earth is damaged

The School has a long and distinguished history, and it is also one of the oldest charities in the country, providing scholarships to pupils and organizing a Charity of the Term.
    The curriculum(课程)at King’s is based on strong academic roots. It emphasizes and relies upon what is best in traditional independent school education: scholarly excellence supported by a caring and tutorial system, and a wide-ranging co-curricular programme. However, it is continually adapting and reacting to the changing demands of modern education: new subjects are added, new teaching techniques adopted, and there is an increasing awareness of the need to provide programmes of study that match individual needs and skills.
    The curriculum is divided into three units: the Lower School (Year 9), an introductory year; the Middle School (Years 10 and 11), working to GCSEs; and the Sixth Form ( Years 12 and 13), taking AS and A levels.  
    Full details can be found in:  Shell Guide and Handbook; Middle School Academic Guide 2009-11; Middle School Academic Guide 2010-12;  Sixth Form Guide 2009-11 and Sixth Form Guide 2010-12.
    Formal and structured educational support, for those who need it, is available at all levels. The well-stocked Library is open 7 days and 6 evenings per week. ICT facilities (including the Internet) are available for all and the whole school (studies within the Houses as well as classrooms) is extensively networked.   
    Pupils are offered extensive careers advice throughout their time at King’s. Almost all go to university, either immediately or following a GAP year.  The most popular university destinations are Cambridge, Bristol, Nottingham, Durham, Leeds, Oxford, Edinburgh, Manchester, and University College, London.

    There are several ways to break the technology code that teenagers have written among themselves. The following are ideas to help parents understand the sometimes confusing world of the teens.
    Social Networking (人际关系网) Sites: Sites like MySpace and Facebook appeal to all generations and are a good way for a parent to understand what social standards your teen is living with. There are many ways to help you take part in your child's online activities. You also can be from an onlooker (旁观者) who keeps a bird' s-eye view of his cyber world to an active member of his social group.
    MMORPG: Massively Multiplayer Online Role-Playing Game comes in the form of games. A child can easily become addicted to (沉溺于) them if no limits are set. To fully understand the attraction behind MMORPG, you can make your own account and character to explore the digital (数码的) world. Playing the online games may seem strange at first to your teen, but experience has led me to only positive feedback (反应) from young people who can communicate with adults about their gaming experiences.
    Text and Instant Messenger: The ways of teenage communication have produced a whole new language, such as "LOLZ" (laughing out loud) and "PSOS" (parent standing over shoulder). Learning the basic shorthand (速记法) of teens can open up a whole new world of communication, not only talking to your teens, but being able to listen on their terms as well. You may just find yourself texting faster and ending your correspondence (联系) with TTYL (talk to you later). To teens, texting anyone looks cool, even Mom and Dad.
    Email: Emailing your child is easy. This, of course, cannot take the place of face-to-face communication, but it provides another way for your child to reach you. Another benefit is that your child cannot act like he didn't hear you.
    小题1:What does the underlined part "appeal to" in the second paragraph mean?
    A．harmB．attractC．upsetD．attack
    小题2:According to this passage we can infer that the author's child __________.
    A．works hard at school
    B．is active on Facebook
    C．enjoys playing online games
    D．likes talking with adults
    小题3:If you are standing beside your child, he is most likely to text his friend __________.
    A．PSOSB．MMORPGC．TTYLD．LOLZ
    小题4:What does the passage mainly tell us?
    A．Parents can use technology to stay in touch with their children.
    B．Many children are very crazy about the online games.
    C．Science and technology make life easy and convenient.
    D．Parents can do something interesting like their children do.

    Ever thought you’d get to experience the smell of ancient Egyptian queen Cleopatra’s hair, or the scent(气味) of the sun? Visitors to the Reg Vardy Gallery will soon be able to do just that.
    The gallery, at Sunderland University, England, is holding a new exhibition “If There Ever Was”. It focuses on scent rather than sight.
    The innovative(创新的) idea is the brainchild of curator(馆长) Robert Blackson. His inspiration came from reading the book Fast Food Nation. The book discussed the use of artificial chemicals to flavor things such as milkshakes, making them smell and taste like strawberries, when they’re not actually made from them.
    A smell can often conjure up(召唤) memories such as school dinners or a childhood holiday by the sea, but the smells on display, will allow visitors to experience smells their noses won’t have been able to pick out before.
    “There’s a whole variety of different smells, including some extinct flowers,” explains Blackson. “Some have been gone for hundreds of years.”
    One extraordinary fragrance(香气) is the aftermath(灾难的后果) of the first atomic bomb, dropped on Japan on August 6,1945.
    There is also the smell of Clepatra’s hair, based on incense(熏香) that was popular among ancient Egyptians.
    The Soviet Mir space station, which burnt up in the atmosphere in 2001, smells of charred(烧焦的) material (the space station caught fire).
    Among the stranger smells is the “surface of the sun”.
    “It is hard to sum up. It is an atmospheric smell, like walking into a room when the sun has been pouring in” says Blackson. “It gives a freshness, a sun kissed feel with a bit of metal. If you can say something smells hot, this is it.”
    A team of 11, including perfume designers, have been working on recreating the smells for the exhibition. James Wong, a botanist（植物学家）at Botanic Gardens Conservation International, UK, helped in the recreation of the smells of four extinct flowering plants.
    He did this by closely linking the extinct flowers with the smells of existing ones. With the help of historical reports of how the extinct flowers smelled, he was able to remix the aromas(芳香).
    The exhibition runs until June 6.Fourteen extinct and impossible smells are on display.
    小题1:What might be the best title of the passage?
    A．The Reg Vardy GalleryB．Egyptian queen Cleopatra’s hair
    C．A visit to a new exhibitionD．The scents of ancient Egypt
    小题2:Visitors can enjoy all of the following scents at the Reg Vardy Gallery EXCEPT  .
    A．the scent of ancient Egyptian queen Cleopatra’s hair
    B．the smells of charred material of the Soviet Mir space station
    C．the scent of having a childhood vacation by the sea
    D．the smell of the aftermath of the first atomic bomb dropped on Japan
    小题3:Which of the following is TRUE according to the passage?
    A．Visitors go to Reg Vardy Gallery to enjoy beautiful sights.
    B．James Wong managed to remix the aromas by referring to some historical reports.
    C．The exhibition will last until July 6.
    D．The scents visitors will smell are found in the tomb (坟墓) of the ancient Egyptian queen Cleopatra.
    小题4:In which session are you likely to read the passage in a newspaper?
    A．ScienceB．EducationC．EntertainmentD．Economy
