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, Mercury (水星) and Venus, are nearer while the other six, namely Mars, Jupiter, Saturn, Uranus, Neptune and Pluto, also in their given order from the sun, are farther from the sun than the earth is. The farther they are, the longer trips they make around the sun, People noticed long ago that these traveling bodies moved around in the sky in definite paths. It is a force called gravity (重力) that holds them in their paths.

We know that every little bit of matter in the universe pulls upon every other bit of matter. The pull between two bodies is proportional (成比例的) to the product of their masses. Because the sun is so large the pull between the sun and the planets are thus great. If it were not for this pull, the planets would fly off into space. In the same way there exists a pull between the earth and the moon, which keeps the moon traveling in its orbit around our planet, the earth. Gravity holds you to its surface, and pulls back to it 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.

Now remember that large bodies exert a greater pull than smaller ones which contain less material. But each object in the universe, no matter how small, pulls on all other objects to some degree.

Happiness is for everyone. You don’t need to care about those people who have beautiful houses with large gardens and swimming pools or those who have nice cars and a lot of money and so on. Why? Because those who have big houses many often feel lonely and those who have cars may want to walk on the country roads at their free time.

In fact, happiness is always around you if you put your heart into it. When you are in trouble at school, your friends will help you; when you study hard at your lessons, your parents are always taking good care of your life and your health; when you get success, your friends will say congratulations to you; when you do something wrong, people around you will help you to correct it. And when you do something good to others, you will feel happy, too. All these are your happiness. If you notice a bit of them, you can see that happiness is always around you.

Happiness is not the same as money. It is a feeling of your heart. When you are poor, you can also say you are very happy, because you have something else that can’t be bought with money. When you meet with difficulties, you can say loudly you are very happy, because you have more chances to challenge yourself. So you cannot always say you are poor and you have bad luck. As the saying goes, life is like a revolving(旋转的) door. When it closes, it also opens. If you take every chance you get, you can be a happy and lucky person.
