    Everyone has got two personalities—the one that is shown to the world and the other that is secret and real. You don’t show your secret personality when you are awake because you can control your behavior, but when you are asleep, your sleeping position shows the real you. In a normal night, of course, people frequently change their positions. The important position is the one that you go to sleep in.
    If you go to sleep on your back, you’re a very open person. You normally trust people and you are easily influenced by fashion or new ideas. You don’t like to displease people. So you never express your real feelings. You’re quite shy and you aren’t quite sure of yourself.
    If you sleep on your stomach, you are a rather secretive person. You worry a lot and you’re always easily upset. You always stick to your own opinions or judgment, but you don’t raise your hope too much. You usually live for today not tomorrow. This means that you enjoy having a good time.
    If you sleep curled up, you are probably a very nervous person. You have a low opinion of yourself and so you’re often defensive. You’re shy and you don’t normally like meeting people. You prefer to on your own. You’re easily hurt.
    If you sleep on your side, you have usually got a well—balanced personality. You know your strengths and weakness. You’re usually careful. You believe in yourself. You sometimes feel anxious, but you don’t often get sad. You always say what you think even if it makes people rather angry.
    【小题1】According to the passage, a person, who is not willing to change his mind and hard to deal with, probably sleeps ___.

    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．

     A warm blanket is the ideal sleep aid for a freezing winter night. The right blanket can warm your bones but the wrong one can affect your sleep. I asked experts for advice on picking the perfect blanket for a good night’s sleep. Here’s what they told me.

         When it comes to sleep temperature, experts recommend following the principle: not too cold, not too hot, but just right. “People seem to sleep best at temperature between 62 and 70 degrees F,” says Dr. Alice Hoagland. When the surrounding temperature falls too low, it can rouse you from sleep. A good blanket helps drive the coldness away.

         At the other extreme, overheating yourself can affect your sleep as well. “Core body temperature typically drops during the first four hour’s of sleep,” says Dr. Hoagland. This decline in body temperature helps you fall asleep and stay asleep.

         “In medical care, weighted blankets are one of our most powerful tools for helping people who are anxious, upset, and possibly losing control,” says Dr. Karen Moore. These special blankets are filled with weighted pellets. Weighted blankets are also marketed for general use as an aid to sleep and relaxation. Like a firm hug, weighted blankets help us feel safe.” This is the reason why many people like to sleep under a blanket even in summer.

         “If you want to try this type of blanket, the best weight depends on your body size and personal preference. However, 15 to 30 pounds is typical for adults,” Moor says. She adds that weighted blankets are not recommended for those recovering from surgery.

         “People can also have serious preferences for a particular blanket,” says Dr. Hoagland. “Regularly using a favorite blanket for sleep can help to develop a conditioned response so that sleep is quicker.” In fact, many sleep centers ask patients to bring their own blanket and pillow from home, which helps them fall asleep more easily.

    1.The author wrote the passage mainly to tell us _____.

    A. the importance of blankets

    B. how to choose the perfect blanket

    C. different materials used to make blankets

    D. the history and usage of blankets

    2.The underlined word “rouse” in Paragraph 2 is the closest in meaning to “______”.

    A. wake up     B. take up     C. make up     D. pick up

    3.What do we know from the passage?

    A. Body temperature rises when we fall asleep

    B. The perfect sleep temperature should be above 70 degrees F.

    C. Weighted blankets should be at least 30 pounds.

    D. People are advised to use their own blankets.

    阅读下面短文，根据所读内容在文章后表格中的空格里填入最恰当的单词。(注意：每空填1个单词。)

    Celebrating sleep

    World Sleep Day, observed （庆祝）on 21 March, was created to bring attention to the growing number of sleep problems worldwide. Sleep is a natural part of human life, but many people in the modern world ignore its importance. As a result, sleep problems are increasingly common.

    In 2002, scientists at the University of Athens in Greece conducted a survey of over 35,000 people in 10 countries around the world, including China, Belgium and South Africa. Of the people, 24 percent said that they did not sleep well, and based on their responses, 31.6 percent were diagnosed (诊断)with insomnia（失眠）and another 17.5 percent were diagnosed with borderline insomnia. In addition, 30.7 percent of survey respondents reported visiting a doctor for help with sleep problems and 11.6 percent said that they felt very sleepy during the day.

    Overall, the survey found that many people suffer the effects of poor quality sleep, some examples of which are being unable to fall asleep and waking up in the middle of the night. The main factors causing these problems are pressure from school or work and a fast pace of life, but noise pollution and light pollution also disturb sleep and contribute to poor quality sleep. The survey’s findings are particularly troubling because large numbers of people were found to have difficulty sleeping at night. The short-term effects of this are tiredness and trouble concentrating（专心）. If this happens for a long time, the risk of putting on weight and having a heart attack may increase.

    There are many things you can do to improve the quality of your sleep. First, you should have regular sleep habits. Try to go to bed and wake up around the same time each day. You also need to make your bedroom a cool, dark, quiet place to sleep so that heat, light and noise do not disturb you. At night, you should also avoid things that contain caffeine（咖啡因）, such as chocolate, coffee, tea and many soft drinks, as caffeine may keep you from sleeping.

    Getting a good night's sleep is important for everyone. By following the advice above, you can rest better at night and work better during the day.
