    B
    Advice to “sleep on it” could be well founded, scientists say. After a good night’s sleep a problem that couldn’t be solved the night before can often appear more manageable, although the evidence（证据）until now has been personal experience. But researchers at the University of Luebek in Germany have designed an experiment that shows a good night’s sleep can improve insight（洞察力）and problem-solving.
    “If you have some newly-got memories in your brain, sleep acts on these memories and rebuild them, so that after sleep the insight into problem which you could not solve before increases,” said Dr Jan Born, a neuroscientist（神经病学专家）at the university. To test the theory, they taught volunteers two simple rules to help them turn some numbers into a new order．There was also a third，hidden rule，which could help them increase their speed in solving the problem．The researchers divided the volunteers into two groups：half were allowed to sleep after the training while the rest were forced to stay awake．Dr Jan Born and his team noticed that the group that had slept after the training were twice as likely to figure out the third rule as the other group．“Sleep helped，”Born said in a telephone interview．“The important thing is that you have to have a memory representation in your brain of the problem you want to solve and then you sleep，so it can act on the problem．”But Born admitted that he and his team don’t know how rebuilding of memories occurs or what governs it．Pierre Maquet and Perrine Ruby of the University of Liege in Belgium said the experimental evidence supports the suggestions that sleep can help develop creative thinking．Although the role of sleep in human creativity will still be a mystery，the research gives people good reason to fully respect their periods of sleep，they added．
    60．The underlined phrase“sleep on it”in Paragraph 1 probably means_________．
    A．to delay deciding something until the next day
    B．to get as much sleep as possible
    C．to go on sleeping without being disturbed
    D．to sleep till after the time you usually get up in the morning
    61．Jan Born and his team carried out the experiment through________．
    A．comparison    B．interview        C．survey          D．imagination
    62．It can be inferred from the passage that___________．
    A．people should sleep so long as they have time
    B．sleep is the only way to solve hard problems
    C．people have various periods of sleep   D．people know how sleep rebuilds memories
    63．What would be the best title for the passage?
    A．How Sleep Works．               B．Sleep Helps Solve Problems．
    C．No Evidence，But Well Founded．   D．Born’s Discovery on Sleep．

    Do you sleep well? Some people get off to sleep as soon as their head hits the pillow, but  many others are not so lucky. In fact, the lack of quality sleep has become a public health issue around the world. According to me World Association of Sleep Medicine, 45 percent of the world's population suffer from sleep problems. One in eight people don't sleep well and are easily woken. 7.6 percent sleep less than 3 hours each night. Some even cannot fall asleep for several days in a row.
    As a basic bodily and mental need, sleep is essential for our survival, it helps us to fight diseases, strengthen our memory, perform better in work and school and improve our quality of life. Lack of sleep is known to have a significant negative influence on health, both in the short and long term. Poor sleep has been associated with obesity, diabetes, weakened immune systems and even some cancers, as well as depression and anxiety.
    The World Sleep Day, held on the third Friday of March, is an annual celebration of sleep to lighten the burden of sleep problems through better prevention and management of sleep disorders.
    To achieve this goal, we must figure out what causes sleepiness and sleeplessness.
    Unhealthy lifestyle may be the first to blame. More and more people use cell phones and computers in bed, with many staying up until midnight. Modern technology does make our life convenient, but abuse of it ruins our health. Environmental conditions, such as temperature, noise, light, bed comfort also play an important Pole in one's ability to get proper sleep. Besides, improper evening diet, like a full or an empty stomach, coffee and alcohol all contribute to sleep problems. Of course, when it comes to causing poor sleep, stress from finances, family or work should never be ignored．
    However, those who suffer from sleep disorders don't necessarily have to continue to do so -most sleep problems can be managed．
    【小题1】What can be inferred from Paragraph 1?

    A．Nobody can stay awake for several days
    B．Most people are going through sleep problems
    C．Sleep problems have become a worldwide concern．
    D．The majority of the world's population can't sleep well．
    【小题2】Which of the following is not a direct cause of sleep problems?
    A．Unhealthy lifestyle．B．Modern technology．
    C．Environmental conditions．D．Work stress．
    【小题3】What will be discussed in the paragraph that follows?
    A．The harm of sleep problems．
    B．Activities on the World Sleep Day．
    C．Interviews of poor sleep sufferers．

    Donald had his own difficulties in sleeping that night. Not just because of the bright lights of the shelter or people’s constant voices, it was the happening repeatedly nightmare that caused him to stay awake, to fear sleep. Donald was back in his small house. He did his best to ignore the howling winds outside his window. Yet he could not turn out the fearful whimpers (呜咽) of his little dog, or the uncomfortable sounds of his mother anxious in her room next door, unable to sleep through the storm despite her insistence they would be all right.

    Donald did not want his mother to be upset, but on some level, he was glad to hear she was awake, It meant he was not alone in the dark. Though he was 12, until recently it was impossible for Donald to fall asleep unless his mother lay down by his side.

    Suddenly there was a crash. Their living room window is shattered (打碎) by 125 miles an hour winds. Troy rushed to Donald and sat anxiously on the edge of his bed. He did his best to calm his mother, and she had to comfort him. Soon water was seeping (渗入) into the single floor house. Quickly it rose from ankle level to leg level. At Donald’s insistence, they pushed their way through the water --- now chest high --- toward the front door. When they fought their way into the living room, water rose to their chins.

    It was a struggle for the boy and mother to stay afloat. In a total panic, desperate to hold on to something, Troy caught a curtain rod. She was breathing hard, shouting that she couldn’t swim.

    Donald cried out, “Mom! Hold on!” Just then Donald also caught a floatable wood board.

    How do you feel after you've stayed up late to finish schoolwork? Or the day after a slumber party? Scientists now say that your answers to these questions may depend on your genes.

    Genes are stretches of DNA that work like an instruction manual for our cells. Genes tell our bodies and brains what to do. People have about 40,000 genes, and each gene can have different forms. So, for example, certain forms of some genes make your eyes blue. Other versions of those genes make your eyes brown.

    In a similar way, new research suggests that a gene called period3 affects how well you function without sleep. The discovery adds to older evidence that period3 helps determine whether you like to stay up late or get up early.

    The period3 gene comes in two forms: short and long. Everyone has two copies of the gene. So, you may have two longs, two shorts, or one of each. Your particular combination depends on what your parents passed on to you.

    Scientists from the University of Surrey in England studied 24 people who had either two short or two long copies of period3. Study participants had to stay awake for 40 hours straight. Then, they took tests that measured how quickly they pushed a button when numbers flashed on a screen and how well they could remember lists of numbers.

    Results showed that the people with the short form of period3 performed much better on these tests than the people with the long form did. In both groups, people performed worst in the early morning. That's the time when truck drivers and other night-shift workers say they have the most trouble concentrating.

    After the first round of experiments, participants were finally allowed to sleep. People in the group that performed well on the tests took about 18 minutes to nod off.

    People with the long period3 gene, by contrast, fell asleep in just 8 minutes. They also spent more time in deep sleep. That suggests that people with the long form of the gene need more and deeper sleep to keep their brains working at top form.

    1.We can know from the passage that genes can not ________.

    A．tell our bodies and brains what to do

    B．make our eyes blue or brown

    C．decide how well you work without sleep

    D．ensure whether you’re good at driving

    2.Which of the following statements about the period3 is wrong?

     

    A．It affects whether you like to stay up late or get up early.

    B．It comes in two forms: short and long.

    C．One has either two longs or two shorts of it.

    D．Your parents determine what particular combination you have.

    3. People with the short form of period3__________.

     

    A．need to go to bed early and get up early

    B．can work better than the people with long form of period3 without sleep

    C．take less time to fall asleep after they stay up late

    D．need more and deeper sleep to keep their brains working at top form

    4.What’s the best title of the passage?

    A．The Period3 Gene

    B．The Function of Genes

    C．Wake up, Sleepy Gene

    D．Stay up Late or Get up Early?
