    Scientists are placing robotic dogs in the homes of lonely old people to test whether they can improve the quality of life for humans. Alan Beck, an expert(专家) in human-animal relationship, and Nancy Edwards, a professor of nursing, are leading the animal-assisted study on the effect of robotic dogs on old people’s depression (沮丧) , physical activity, and life satisfaction.
    In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, scientists will collect baseline data(数据) for six weeks. These old people will keep a diary to note their feelings and activity before and after AIBO. Then, the scientists will review the data to test if it has produced any changes in the life of its owner.
    “I talk to him all the time, and he responds to my voice,” says a seventy-year-old lady. “When I’m watching TV, he’ll stay in my arms until he wants down. He has his own mind.”
    The AIBOs respond to certain orders. The scientists say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns.
    “At the beginning, it was believed that no one would relate(与……相关) to the robotic dog, because it was metal and not furry.” Beck says. “Hopefully, down the road, these robotic pets could become a more-valuable health helper. They will record their masters’ blood pressure, oxygen levels or heart rhythms(心律). AIBOs may even one day have games that can help stimulate(刺激) older people’s minds.”
    小题1:The purpose of Beck and Edwards’ study is to _____________.
    A．understand human-animal relationship
    B．make lonely old people’s life better
    C．find the causes of old people’s loneliness

    小题2: In the research, the old people are asked to _____________.
    A．note the activities of AIBOs
    B．keep AIBOs at home for 12 weeks
    C．record their feelings and activity
    D．study the collected information
    小题3:What does the underlined word “removes” mean?
    A．moves againB．is movableC．doesn’t needD．need
    小题4:What is the better point of AIBO than live dogs?
    A．It is easier to keep at home.
    B．It can help the disabled people.
    C．It responds to all the human orders.
    D．It can watch TV with its owner.
    小题5:The writer seems to suggest that the future robotic dogs may__________.
    A．cure certain diseasesB．keep old people active

    What does it feel like to break a bone (骨头)? It’s different for everyone, but the pain is often sharp (严重). If the break is small, however, the person may not feel much pain at all. If you think that you or someone else has broken a bone, the most important things to do are to stay calm, make the hurt person comfortable, and call the doctor. Do not move the injured body part since movement could make it worse.
    To treat the break, the doctor will need to take an X-ray. This gives the doctor the information he or she needs to set (接上) the bone: to put it back to its normal place. If the bone is large or it is broken in more than one place, the doctor may need to use metal pins (钢钉) to set it. After the bone has been set, the next step is usually putting on a cast, the special, hard thing that will keep the bone in place for a month or two.
    Your bones are excellent at healing themselves. Broken bones will produce many new cells (细胞) and tiny blood vessels (血脉). These cover both ends of the broken part, and close up the break until the bone is as whole and strong as before.
    小题1: Which of the following is the best title for the passage?
    A．How to Know if a Bone is Broken
    B．How Broken Bones Heal Themselves
    C．Common Causes (原因) of Broken Bones
    D．What You Should Know about Broken Bones
    小题2: When someone breaks his bone, the following should be done except ______.
    A．asking the doctor for helpB．comforting the hurt person
    C．moving the injured partD．staying calm
    小题3:Which is the correct order to treat the break?
    a. take an x-ray  b. use metal pins to set it  c. put it back to its normal place  d. put on cast
    A．a→b→c→dB．a→c→b→dC．a→d→c→bD．d→a→b→c
    小题4:The underlined word “heal” in Paragraph 3 is closest in meaning to “______”.
    A．break againB．become worse C．wound or hurtD．become healthy again
    小题5: Where would you probably read this passage?
    A．In a story book.B．On a poster.C．In a health care book.D．In a chemistry book.

    Teeth are important. Strong, healthy teeth help you chew foods that help you grow. They help you speak clearly. And, they help you look your best. Here are some advice for you to take care of your teeth.
    ● Brush your teeth the right way.
    Brush your teeth at least twice a day after breakfast and before bedtime. If you can, brush after lunch or after sweet snacks（快餐）, too.

    Get a new toothbrush every three months. When you buy your tooth brush, be sure it has soft bristles（鬃毛）.

    What makes 15,000 men and women run for hours, and what makes them run through the streets on a cold day without coats? I was one of those runners.  The race is called marathon (马拉松).
    I had never run more than eight miles before, and here I was training.  Since the race is in April, I had to run throughout the winter, and in Boston, winters are cold. For most people, just putting on their shirts, sweaters, jackets, and hats is exercise enough. I found myself out on the dark streets, running along ice sidewalks (人行道). Even in gloves, my fingers got so cold that they looked like red carrots. My nose didn’t get warm until lunchtime !
    Finally, the big day arrived. The weather was cold, with ice and rain. Bang! The gun sounded, and we started. I didn’t go anywhere at first because I was standing behind so many people. I had to wait for them to move.
    At first, the running was easy.  The other runners just seemed to pull me along. Somewhere around the 20-mile mark I even said to myself, "This is nothing, why did I train so hard?"
    Then I hit "the wall". "The wall" is what marathon runners call the special point. I knew my body reached the point and I thought I couldn’t go any more. I was out of breath and my legs turned into pieces of wood.  I was almost falling down.  I can’t remember anything about the last five miles of the race.
    I kept running though. At last, I heard a voice at the finishing line.
    "You look good," my friend Ted said. "How did it feel?"
    "Wonderful !" I replied.
    For everything, if you devote yourself into it, there will be a way. I finished the race, at least, in my heart, I was the winner.
    小题1:Which one best describes the weather on the race day?
    A．Cold and rainy.B．Cold and sunny.C．Dry and cloudy.D．Wet and foggy.
    小题2: How did the writer feel about the race during the first 20 miles?
    A．Difficult.B．Boring.C．Easy.D．Interesting.
    小题3: According to the article, what must someone do to prepare for a marathon?
    A．One must eat certain food and get plenty of sleep.
    B．One must be willing to eat, sleep, and train twenty-four hours a day.
    C．One must run along ice sidewalks every day.
    D．One must be willing to train a lot and doesn’t give up easily.
    小题4:Then I hit "the wall". What do you think "hit the wall" means here?
    A．撞击墙壁B．到达极限C．抵达终点D．中途加速
