The earth is not the only body that travels around the sun. With it are eight other planets, fellow members of the sun' s family. Two of them are nearer while the other six are farther from the sun than the earth is. The farther they are, the longer trip they make around the sun. People noticed long ago that these traveling bodies moved around in the sky in certain paths.
We know that every little hit of matter in the universe pulls upon every other hit of matter. The pull between two bodies is proportional (成比例的) to the product (乘积) of their masses. Because the sun is so large, the pulls between the sun and planets are thus great. If it were not for these pulls, the planets would fly off into space. In the same way there is a pull between the earth and the moon, which keeps the moon traveling in its orbit (轨道) around our planet, the earth. The pull holds you to its surface, and pulls back the ball which you throw into the air. Of course the ball also pulls on the larger earth but the earth is so much larger that the pull is not noticed.
(1) The earth travels a larger circle around the sun than ________ .
[ ]
A. six of the other planets
B. two planets in the same family
C. most planets in the universe
D. the moon
(2) The planets move around the sun because of ________ .
[ ]
A. the gravity (引力) of the sun only
B. the pull of the planets on one another
C. the pull between the planets and the sun
D. the proportional gravity
(3)If objects (物体) didn't have gravity, ________ .
[ ]
A. the earth would not travel in the space
B. the moon would move away from the earth
C. the sun would not exist
D. the planets of the sun family form another family
(4) Which of the following pictures shows correctly the pull between the objects?
[ ]
(5) The sun's family has ________ members in this text.
A. two
C. nine
D. eight
B. six
[ ]
Simon has read Amy's article about ORBIS in the school newsletter and has become very interested. He finds another article about the history of ORBIS. Read it with him.
ORBISIn the past, eye doctors and nurses in poor countries could not study outside their own countries because they could not afford to traveland pay for their school fees. Dr David Paton was a famous eyedoctor in America. He knew that more than 60 per cent of blind people are in poor countries. It is important to train eye doctors and nurses in these poor countries to cure their patients. So in the mid-1970s, he set up ORBIS.
United Airlines donated a DC-8 plane to ORBIS. There was newmedical equipment inside the plane. It is not an ordinary hospital.It is a flying eye hospital. The plane started to fly to different poor countries in 1982. The eye doctors and nurses on the plane taught the local doctors new skills and knowledge.They also did operations together to cure patients with eye problems in poor countries.
In 1992, three generous people donated more money to ORBlS. With their donations, ORBIS bought a new plane, DC-1O. The inside of the plane is twice the size of DC-8. Its first trip was to go to Beijing,China in 1994.
A lot of people suffer from blindness. The ORBIS doctors found that 80per cent of blindness in poor countries can be cured or prevented. So it also carries out special programmes to teach people how to preventeye problems.
To blind people, ORBIS brings new hope and light. Over the past 30 years, ORBIS has successfully helped 130,000 people around the world. TO those who can see, ORBIS is something we can be proud of .
Simon wants to write a report about ORBIS. He is checking his notes before writing his report. Write a T if the sentence is true. Write an F if it is false.
(1) ORBIS often files to poor countries. ________
(2) Dr Paton set up ORBIS. ________
(3) ORBIS is an ordinary hospital. ________
