　　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

　　Jack is the name of a game. It is very popular with children. To play jacks, you will need a small ball and ten small other objects（物体）called jacks.

　　The rules for this game are not complicated（错综复杂）. To begin, you put the ten jacks on the floor or ground in front of you. Toss the ball up (but not too high), pick up one jack, and then catch the ball. Keep（保留）the jack in your hand and then go on to pick up the other jacks one at a time. You lose（负于）your turn if you do not catch the ball, you do not pick up a jack, or you drop（失落）any jacks from your hand.

　　When you finish all ten jacks, you now try to do the same thing again but with two jacks at one time. This is more difficult, of course. You lose your turn if you make any of the other three mistakes（错误）or if you do not pick up two jacks each time!
