题目内容

    Suppose the year is 1666 and we can see a student called Isaac Newton. He’s away from his university for a holiday and at home with his family. Isaac Newton continues to study at home. He enjoys physics and thinking about the mysteries of the world.

    On a day there is rain and sun at the same time, so he sees a beautiful rainbow( 彩虹 )in the sky. It has many different colors. He is told that there are five. Newton wants to have his own rainbow because he wants to look at it closely. He decides to do an experiment. On a sunny day he goes inside a small room and makes the room very dark. Then he makes a small hole and the sun comes inside; it’s a small ray of light. It’s white. Newton takes a prism( 棱镜 ) and holds it up to the light. The ray of light goes through the prism, but it isn’t white now---there are many colors. The prism has split up ( 分解 ) the white into different colors: Newton has a rainbow.

    Newton looks at his rainbow carefully. He can see more than five colors, and he can see seven. He says the colors are: red, orange, yellow, green, blue, indigo and violet.

    But Newton is a scientist and he’s always very interested in how things work.  He has his rainbow but he wants to know more. So he takes another prism and holds it up to the rainbow. The rainbow goes through the second prism, but it isn’t colorful now---it’s white again. The prism has joined up the colors back into white light. Newton is the first person to understand that light is a combination ( 结合 ) of all the rainbow colors together.

1. In 1666 Isaac Newton was _____.

  A. a famous doctor                        B. an assistant in a lab

  C. a university teacher             D. a university student

2. What is the Chinese meaning of the words “ray of light”?

  A.光线           B. 光圈             C. 光速           D.灯光

3. The prism can split up the white into ____.

  A. less than five different colors              B. seven different colors

  C. five different colors              D. more than seven different colors

4. Which of the following is RIGHT according to the sentences underlined(画线)?

 

        A                  B                C                D

5. Which of the following is NOT according to the passage?

  A. Newton did his experiment on a sunny day.

  B. Newton continued his study at home during his holidays.

  C. If we put five different colors together, we get the white light.

  D. Newton can see seven different colors in his experiment.
