The rockets take astronauts and man-made satellites into space. The satellites are used for communication, weather monitoring and research. But how do satellites stay up without falling down?
There are two opposite forces (力量) acting on the satellite. One of them is the force of gravitation (地心引力), which tries to pull the satellite towards the earth. The other force is created by the rotation (旋转) of the satellite around the earth. This force tries to take the satellite away from the earth. With these two forces, the satellite goes round and round. The gravitational pull of the earth (the force which pulls everything towards the ground) is like a rope which keeps the satellite from flying away.
Everything that goes up has to come down. It is only a matter of time before a satellite comes back to the earth. As time goes by, the satellite loses its speed, which makes the gravitational pull stronger than the force pulling it away. This makes the satellite crash (坠落) down to the earth.

Started in 1636, Harvard (哈佛) University is the oldest of all the colleges and universities in the United States. Yale, Princeton, Columbia and Dartmouth were opened soon after Harvard.
In the early years, these schools were nearly the same. Only young men went to college. All the students studied the same subjects, and everyone learned Latin and Greek. Little was known about science. And few people knew that one kind of school could teach everything that was known about the world. When the students graduated, most of them became ministers or teachers.
In 1782, Harvard started a medical school for young men who wanted to become doctors. Later, lawyers could study in Harvard’s law school. In 1825, besides Latin and Greek, Harvard began to teach modern languages, such as French and German. Soon it began to teach American history.
As knowledge increased, Harvard and other colleges began to teach many new subjects. Students were allowed to choose the subjects that interested them.
Today, there are many different kinds of colleges and universities. Most of them are made up of smaller schools that deal with special fields of learning. There’s so much to learn that one kind of school can’t offer all.
