    Early to bed, early to rise, makes a man healthy, wealthy and wise.

    This is an old English saying. Do you know it before? It says that we must go to bed early and get up early in the morning. Then we should be healthy. We should also be rich (wealthy) and clever (wise).

       This is true. The body must have enough sleep to be healthy. Children of a young age should have ten hours’ sleep every night. Children who don’t have enough sleep can’t do their work very well. They will not be wise and they may not become wealthy!

       The body also needs exercise. Walking, running, jumping, swimming and playing games are all exercise. Exercise keeps the body strong.

       Exercise also keeps the blood（血液）moving around inside the body. This is very important. Our blood takes food to all parts of our body. The head also needs blood. Exercise helps us to think better!

    1.If a child doesn’t have 10 hours’ sleep every night, he _____.

    A. will become wise 

    B. won’t do well in his work

    C. will have to sleep in the daytime

    A study finds that not enough morning light causes teenagers not to get enough sleep at night. “As teenagers spend more time indoors, they miss necessary morning light. Day light is needed to keep the balance of the body’s 24-hour biological system (生物系统), which regulates (调节) body temperature and sleep styles,” reports Dr. Mariana Figueiro. “These teenagers who receive little morning light are going to bed later, getting less sleep and doing badly in tests. They are more likely to fail in their exams.”
    In the study, Dr. Figueiro asked 11 students in Grade 8 to wear special glasses to prevent blue morning light from reaching their eyes. At the end of the 5-day study she found that they fell asleep 30 minutes later than usual.
    Throughout her research, Dr. Figueiro has been very worried about teenagers going to bed too late. The problem is that today’s schools require teenagers to be in school very early in the morning. These students are likely to miss the morning light because they often go to school before the sun is up or as it’s just rising.
    Furthermore (此外), the schools are not likely to provide enough electric light to keep the balance of this biological system. Our biological system is much more sensitive (敏感的) to blue light. Therefore, having lots of light in the classroom does not make sure that there is enough light to keep our biological system balanced.

    1. 1.

      Which of the following is the result of the study?

      1. A.
        Blue light in the morning harms the biological system.
      2. B.
        Not enough morning light keeps teenagers sleep less.
      3. C.
        Not getting more light in the morning make teenagers happy.
      4. D.
        Not enough sleep makes teenagers fail in tests.
    2. 2.

      We know from the passage that morning light __________.

      1. A.
        has the same effects as afternoon light
      2. B.
        may change studying habits of teenagers
      3. C.
        is important to children’s biological system
      4. D.
        has no effect on students’ tests
    3. 3.

      What’s the problem of the students according to the study?

      1. A.
        There are not enough electric lights in the classroom.
      2. B.
        Being in school early affects their study habits.
      3. C.
        They have to go to bed very early to have enough sleep.
      4. D.
        They go to school too early to get enough morning light.
