    16．Getting less sleep has become a bad habit for most American kids．According to a new survey（调查） by the National Sleep Foundation，51% of kids aged 10 to 18 go to bed at 10 pm or later on school nights，even though they have to get up early．Last year the Foundation reported that nearly 60% of 7-to 12-year-olds said they felt tired during the day，and 15% said they had fallen asleep at school．
    How much sleep you need depends a lot on your age．Babies need a lot of rest：most of them sleep about 18 hours a day!Adults need about eight hours．For most school-age children，ten hours is ideal（理想的）．But the new National Sleep Foundation survey found that 35% of 10-to 12-year-olds get only seven or eight hours．And guess what almost half of the surveyed kids said they do before bedtime？Watch TV．
    "More children are going to bed with TVs on，and there are more opportunities（机会） to stay awake，with more homework，the Internet and the phone，"says Dr．Mary Carskadon，a sleep researcher at Brown University Medical School．She says these activities at bedtime can  get kids all excited and make it hard for them to calm down and sleep．Other experts say part of the problem is chemical．Changing levels of body chemicals called hormones not only make teenagers'bodies develop adult characteristics，but also make it hard for teenagers to fall asleep before 11 pm．
    Because sleepiness is such a problem for teenagers，some school districts have decided to start high school classes later than they used to．Three years ago，schools in Edina，Minnesota，changed the start time from 7：25 am to 8：30 am．Students，parents and teachers are pleased with the results．

    25．What is the new National Sleep Foundation survey on？A
    A．American kids'sleeping habits．
    B．Teenagers'sleep-related diseases．
    C．Activities to prevent sleeplessness．
    D．Learning problems and lack of sleep．
    26．How many hours of sleep do 11-year-olds need every day？C
    A.7 hours．B.8 hours．C.10 hours．D.18 hours．
    27．Why do teenagers go to sleep late according to Carskadon？B
    A．They are affected by certain body chemicals．
    B．They tend to do things that excite them．
    C．They follow their parents'examples．
    D．They don't need to go to school early．

    3．Population Change      Why is the world's population growing？The answer is not what you might think．The reason for the explosion is not that people have been reproducing like rabbits，but that people have stopped dropping dead like flies．In 1900，people died at the average age of 30．By 2000 the average age was 65．But while increasing health was a typical feature of the 20th century，declining birth rate could be a defining one of the 21st．
          Statistics show that the average number of births per woman has fallen from 4.9 in the early 1960s to 2.5 nowadays．Furthermore，around 50% of the world's population live in regions where the figure is now below the replacement level（i．e.2.1 births per woman）and almost all developed nations are experiencing sub-repalanement birth rate．You might think that developing nations would make up the loss（especially since 80% of the world's people now live in such nations），but you'd be wrong，Declining birth rate is a major problem in many developing regions too，which might cause catastrophic global shortages of work force within a few decades．
          A great decline in young work force is likely to occur in China，for instance．What does it imply？First，China needs to undergo rapid economic development before a population decline hits the country．Sencond，if other factors such as technology remain constant，economic growth and material expectations will fall well below recent standards and this could invite trouble．
          Russia is another country with population problems that could break its economic promise．Since 1992 the number of people dying has been bigger than that of those being born by a massive 50%，Indeed official figures suggest the country has shrunk by 5% since 1993 and people in Russia live a shorter life now than those in 1961．Why is this occurring？Nobody is quite sure，but poor diet an above all long-time alcoholism have much to do with it．If current trends don't bend．Russia's population will be about the size of Yemen's by the year 2050．
          In the north of india，the population is booming due to high birth rates，but in the south，where most econmoic development is taking place，birth rate is falling rapidly．In a further twist，birth rate is highest in poorly educated rural arceas an lowest in highly educated urban areas．In total，25% of India's working-age population has no education．In 2030，a sixth of the country's potential work force could be totally uneducated．
          One solution is obviously to import foreign workers via immigration．As for the USA，it is almost unique among developed nations in having a population that is expected to grow by 20% from 2010-2030，Moreover，the USA has a track record of successfully accepting immigrants．As a result it's likely to see a rise in the size of its working-age population and to witness strong economic growth over the longer term．

    71．lower   72．size/scale  73．immediate74．economic75．old/older

    20．After years of heated debate，gray wolves were reintroduced to Yellowstone National Park．Fourteen wolves were caught in Canada and transported to the park．By last year，the Yellowstone wolf population had grown to more than 170 wolves．
        Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States，but they were gradually displaced by human development．By the 1920s，wolves had practically disappeared from the Yellowstone area．They went farther north into the deep forests of Canada，where there were fewer humans around．
       The disappearance of the wolves had many unexpected results．Deer and elk populations-major food sources （来源） for the wolf-grew rapidly．These animals consumed large amounts of vegetation （植被），which reduced plant diversity in the park．In the absence of wolves，coyote populations also grew quickly．The coyotes killed a large percentage of the park's red foxes，and completely drove away the park's beavers．
       As early as 1966，biologists asked the government to consider reintroducing wolves to Yellowstone Park．They hoped that wolves would be able to control the elk and coyote problems．Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets．
        The government spent nearly 30 years coming up with a plan to reintroduce the wolvers．The U．S．Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone．Today，the debate continues over how well the gray wolf is fitting in at Yellowstone．Elk，deer，and coyote populations are down，while beavers and red foxes have made a comeback．The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well．
    28．What is the text mainly about？D
    A．Wildlife research in the United States．
    B．Plant diversity in the Yellowstone area．
    C．The conflict between farmers and gray wolves．
    D．The reintroduction of wolves to Yellowstone Park．
    29．What does the underlined word"displaced"in paragraph 2 mean？C
    A．Tested．B．Separated．C．Forced out．D．Tracked down．
    30．What did the disappearance of gray wolves bring about？A
    A．Damage to local ecology．     B．A decline in the park's income．
    C．Preservation of vegetation．  D．An increase in the variety of animals．
    31．What is the author's attitude towards the Yellowstone wolf project？B
    A．Doubtful．B．Positive．C．Disapproving．D．Uncaring．
