    Have you ever stayed up late? If so, you know that not getting enough sleep can leave you tired and grumpy . Not sleeping enough can also make it harder to think clearly the next day.
    Sleep experts have long known that getting a good night’s sleep is important.
    It helps kids perform their best during the day. A recent study shows that sleep helps improve problem--- solving skills and creative thinking.
    For the study, two groups of volunteers answered a math problem. The group that slept for eight hours solved the problem correctly more often than the group that did not get enough sleep.
    While you sleep, your brain is busy doing its “homework”. It sorts out information from your day. Getting enough sleep each night can boost your brainpower. That will help you do your best in school. Experts say that, in return, can lead to better grades.

    Forgiving someone who has hurt you or let you down is never an easy thing. Several new studies, however, say that it could have a lot of health benefits. When you think of forgiveness, you probably don’t think of it as being a health or medical problem. Studies from Stanford University, on the other hand, show that something like anger can change your well-being.
    When cartoon book characters like the Incredible Hulk get angry, they change colours and often gain special power. In the real world, anger is less obvious and may be more dangerous. That’s why Professor Fred Luskin, founder of the Stanford Forgiveness Project and author of Forgive for Good, says holding on to anger and hatred can harm your physical and mental health. Two new studies seem to show the same idea.
    The studies find that people who are able to forgive feel less stress, less back pain, and less depression. They also have fewer headaches, lower blood pressure, and fewer problems on sleeping.
    So it doesn’t matter if your anger is caused by the traffic or other things. Learning to let it go is important. Techniques such as deep breath or thought can help. Or just ask yourself if it’s worth hurting yourself by staying angry with someone else.
    Forgiveness does not mean that you simply accept what happened and say it’s OK. Instead, it’s a way of making peace with yourself about what happened in the past.

    Most children, even the youngest of children, are delighted to be around cats and dogs. But these pets carry plenty of germs and allergens（过敏原）,prompting researchers to ask: Are cats and dogs really safe for children？
    A study finds that, contrary to many parents' fears, owning cats or dogs does not increase a child's risk of developing allergies, and in fact, may actually protect them. The study's lead author, Dr. Dennic Ownby of the Medical College of Georgia, says that even he was "very surprised" by the results. Ownby and colleagues followed more than 470 children from birth to age 6 or 7, comparing those exposed to cats and dogs during their first year of life to those who were not.
    By using skin-prick tests for detecting common allergies, the researchers found that, contrary to what many doctors had been taught for years, children who had lived with a pet were not at greater risk.
    Even more remarkable, children who had two or more dogs or cats had an even greater reduction, up to 77 percent, in risk of allergies. Researchers suggest this protective effect may be the result of early exposure to lots of bacteria that are carried by dogs and cats. Exposing young children to these bacteria helps" exercise" their immune systems early in life so that they're better able to resist allergic diseases later.
    There's something very important in that first year of life when the immune system is developing that we can retrain it away from an allergic response, said Dr. William Davis.
    And while researchers are not encouraging parents to buy dogs or cats just to reduce a child's allergy risk, they say if a family already has one or more animals, there's no need to get rid of them.
    小题1:Why do the researchers feel “very surprised” by the results of the study?
    A．Because the results are contrary to their expectation．
    B．Because so many children are playing with cats and dogs．
    C．Because parents are so much worried about their children．
    D．Because children with animals may develop allergies easily．
    小题2:Compared with children who have pets，those who haven’t  ______.
    A．will lose the chance to develop immune system
    B．may suffer allergic diseases more often
    C．will reduce the harm from bacteria
    D．can keep doctors away
    小题3:It can be inferred from the passage that ______．
    A．pets are ill-treated by their owners
    B．less families would like to own cats and dogs
    C．keeping pets is a good way to keep children healthy
    D．the results of the study can make families with pets feel at ease
    小题4:The underlined word “it” in the fifth paragraph refers to________.
    A．the early life
    B．an allergic disease
    C．immune system
    D．something important
    小题5:What may be the best title of the passage?
    A．How to protect your kids from allergies
    B．Your pets may be helping your kids
    C．Bacteria do good to your kids
    D．Advantages of owning pets

    H5N1 avian influenza, commonly known as bird flu (流感), has killed at least 15 people across Asia and was proved in China on January 27. No human cases have been found in the main­land, but 13 of the country’s 31 provinces have reported the disease in poultry.
    The Chinese government has taken measures to prevent and control the disease. Poultry within 3 km of infected (受感染的) farms is to be killed and those within 5 km vaccinated (接种疫苗). At the same time, there will be continuous monitoring and daily reports on the disease across the country, and in­creased production of bird flu vaccines.
    Among the 11 Asian countries and regions having bird flu in animals, only Vietnam and Thailand have reported human cases. The people infected were reported to have caught the disease from poultry.
    While the World Health Organization ( WHO) says there is “no proof (证据) of human-to-human infection (传染)” of bird flu, the big fear is that the disease could combine with a human flu virus (病毒) to produce a deadly new disease that will kill millions of people across the world. Many Asian farmers live closely with their animals and sell live chickens in the market. This greatly increases the chance of humans being infected with bird flu.
    A spokesman of the WHO said that Asian countries having bird flu should introduce a more healthy way of raising and selling chickens. The people there have to completely change their way of life and manners towards animals. Here are some safety measures for people to stay healthy;
    *   Keep fit through usual exercise;
    *   Avoid infected poultry and infected people;
    *   Avoid eating uncooked or under-done poultry and eggs;
    *   Make sure there is always fresh air in your home;
    *   Cover your mouth and nose when coughing or sneezing;
    *   Wash your hands as often as possible.
    小题1:What does the underlined word “poultry” mean?
    A．Wild birds.
    B．Wild animals.
    C．Home-raised birds.
    D．Home-raised animals.
    小题2:From the passage, we learn that __________.
    A．infected poultry within 3 km was killed in China
    B．the first bird flu case was proved in China on Jan. 27
    C．human infected cases were found in 11 Asian countries
    D．over two thirds of China have been affected by the bird flu
    小题3: What do people fear most?
    A．Poultry will infect many people.
    B．There will be human-to-human infection.
    C．The disease can spread quickly among people.
    D．A new disease combining bird flu and a human flu will break out.

    When you close your eyes and try to think of the shape of your own body, what you imagine (or rather, what you feel) is quite different from what you see when you open your eyes and look in the mirror. The image you feel is much vaguer（模糊的） than the one you see. And if you lie still, it is quite hard to imagine yourself as having any particular size or shape.
    When you move, when you feel the weight of your arms and legs and the natural resistance of the objects around you, the “felt” image of yourself starts to become clearer. It is almost as if it were created by your own actions and the feelings they cause.
    The image you create for yourself has rather strange proportions（部分）; certain parts feel much larger than they look. If you get a hole in one of your teeth, it feels enormous; you are often surprised by how small it looks when you inspect it in the mirror.
    Although the “felt” image may not have the shape you see in the mirror, it is much more important. It is the image through which you recognize your physical existence in the world. In spite of its strange proportions, it is all one piece, and since it has a consistent(前后一致的) right and left and atop and bottom, it allows you to locate new feelings when they occur. It allows you to find your nose in the dark and point to a pain.
    If the felt image is damaged for any reason—if it is cut in half or lost as it often is after certain strokes （中风）which wipe out recognition of one entire side –these tasks become almost impossible. What is more, it becomes hard to make sense of one’s own visual appearance. If one half of the “felt” image is wiped out or injured, the patient stops recognizing the affected part of his body. It is hard for him to find the location of feelings on that side, and, although he feels the doctor’s touch, he locates it as being on the undamaged side.
    小题1:According to the passage the “felt” image       the mirror image.
    A．is precisely the same asB．is as clear as
    C．often differens fromD．is always much smaller than
    小题2:Which the following staterants is NOT true?
    A．The felt Image is much more important because it helps you locate new feelings.
    B．When you are in bed with your eyes closed, it is not easy to imagine your image.
    C．When you move, the “felt” image of yourself starts to become clearer.
    D．The “felt” image is not so important as the mirror image.
    小题3:If a man loses the ability to recognize his right side,           .
    A．he can’t locate the doctor’s touch on his left side
    B．he can’t locate the doctor’s touch on his right side
    C．he loses his sense of touch on the left side
    D．he loses feeling on both sides
    小题4:What is this passage mainly about?
    A．Stroke victims’“felt” imagesB．Stroke victims’ mirror images.
    C．The importance of “felt” imagesD．The importance of mirror images.

    Many grown-ups worry that spending too much time playing video games isn’t good for a kid’s health. But some doctors have noticed that kids who bring their game players to the hospital seem less worried about being there. They also seem to feel less pain when they are giving all their attention on a car race or other games.
    At a children’s center in Baltimore, Maryland, young kids are finding hospital visits easier to deal with, thanks to a test program called HOPE. Patients in HOPE have a life-threatening condition where their kidneys(肾) no longer get rid of wastes from their blood. To get their blood cleaned, these kids must use the dialysis (透析) machines at the hospital three times a week, for at least three hours each time. HOPE allows kids to play Internet sports, racing, and other games with each other. They will be able to connect with kids in other hospitals who have the same problem. “We want to use the Internet to bring together kids who are ill, and let them know they are not alone,” said Arun Mathews, the doctor of the program. He loved video games himself and got the idea to connect kids all over the country.
    Many researchers elsewhere are testing video programs that might help young patients. For example, nine-year-old Ben Duskin of San Francisco, California, who was struggling with cancer helped to design a video game where players got rid of cancer cells.
    That’s all great news, because doctors already know that reducing pain and worry helps patients heal(痊愈) faster.

    A．use the dialysis machinesB．are in a car race

    If you have to miss one meal a day, which meal will cause you fewest health problems if you don’t eat it? If they have to make a decision of this type, most people (especially very busy people) will choose to skip (not to eat) breakfast.
    However, many experts in the field of health consider breakfast (the meal which “breaks” your “fast---- a period of time without eating anything ” which started the night before) to be the most important meal of the day. If we eat a good breakfast, they say, we will have the energy and nutrients we need to begin our working day with vigor and hopefully with good humour. But many people skip breakfast or replace it with snacks or a cup of coffee for a well-balanced meal. What happens if we ignore the importance of breakfast?
    One recent study conducted in the United States tested a large number of people. Participants included both males and females who ranged in age from 12—83. During the experiment, these people were given a variety of breakfasts, and sometimes, they had to skip breakfast completely. Special tests, including blood tests and endurance tests, were set up to analyze how well the participants’ bodies functioned when they had eaten a certain kind of breakfast.
    The result showed that if a person eats an adequate (充足的) breakfast, he or she will work more efficiently and more productively than if he or she skips breakfasts or eats a very poor breakfast. This fact appears to be especially true if a person’s work involves mental activity. The study showed that if schoolchildren eat fruit, eggs, bread and milk before going to school, they will learn more quickly and will be able to concentrate on their lessons for a longer period of time than if their breakfast diet is inadequate .
    The study also showed that, contrary to what many people believe, if you skip breakfast, you will not lose weight. This is because people become so hungry if they skip breakfast that they eat too much for lunch and end up gaining weight instead of losing. So remember, if you are on a diet, skipping breakfast will not help you. You will probably lose more weight if you reduce your other meals.
    小题1:According to the passage, we can safely say _____.
    A．if you skip breakfast, you will not lose weight at all
    B．if you skip breakfast, you won’t eat much for lunch either.
    C．skipping breakfast won’t do a bit of harm
    D．skipping breakfast will help one lose weight
    小题2:In the word “breakfast”, “fast” probably means _____.
    A．“moving quickly”B．“going without food ”
    C．“unlikely to go fast”D．“fast food ”
    小题3:Special tests were organized to analyze how participants’ bodies functioned when ______.
    A．they had skipped breakfasts B．they had had breakfasts
    C．they had eaten special breakfasts D．they had had all three meals
