    题目列表(包括答案和解析)

    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.

        Being in school early affects their study habits.
      3. C.
        They have to go to bed very early to have enough sleep.
      4. D.

    A lift is wonderful. It is really only a small room. Rooms usually stay in one place. Lifts travel up and down all day long.
    Sometimes a worker stands in the lift. He or she operates it up and down. In modern lifts there is no worker. The people walk in. They know what floor they want. They push a button and the lift goes to that floor. It is all very fast and easy.
    Lifts are very important to us. Why? Think about a tall building. Maybe it has twenty floors. Maybe it has fifty or more. Who can walk up all the stairs? Maybe people can climb them one time. Can someone climb thirty floors to an office every day? Can small children walk up to their room on the twenty-fourth floor? Can their mother and father carry food up all those stairs? Of course not.
    We can have high buildings because we have lifts. We could not have all the beautiful tall buildings in the world without lifts. They are really wonderful.
