The sun seems to rise in the east, move across the sky, and set in the west．In other words, the sun seems to travel round the earth．However, this is not really true．It is the earth which is turning on its own axis(轴)．
The earth rotates(旋转), or turns on its axis．It rotates once in 24 hours．The turning of the earth on its own axis is what makes the change from day to night．The earth revolves(旋转)around the sun too．It revolves once a year．
The robit(天体运行轨道)of the earth is not a perfect circle．It is oval．The earth's axis is not at a right angle to its orbit, but it is tilted(使倾斜)a little．The turning of the earth round the sun at this angle and in an oval-shaped orbit is what makes the change of the seasons．
Nowadays, all these ideas are well-known truths, but it took people a long, long time to be sure about them．It took a lot of thinking, a lot of looking．It took lots of arguments too．

We are all busy talking about and using the Internet(因特网), but how many of us know the history of the Internet?
Many people are surprised when they find that the Internet was set up(建立) in the 1960s. At that time, computers were large and expensive. Computer networks(网络) didn't work well. If one computer in the network broke down, then the whole network stopped. So a new network system(系统) had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information(信息) could be sent through another part. In this way computer network system would keep on working all the time.
At first the Internet was only used by the government(政府), but in the early 1970s, universities(大学), hospitals and banks(银行) were allowed(允许) to use it too. However, computers were still very expensive and the Internet was difficult to use. By the start of the 1990s, computers became cheaper and easier to use, Scientists had also developed software(软件) that made “surfing”(浏览) the Internet more convenient(方便).
Today it is easy to get on-ling(上网) and it is said that millions of people use the Internet every day. Sending email(电子邮件) is more and more popular among students.

What a beautiful day!
The sun is shining and everything looks bright. Stand in tile sun. Can you feel the heat of the sun? The sun that gives the heat is very far away. It is hard to believe, but the sun is about one hundred and fifty million kilometers away. If a plane flew day and night without stopping, it would take nearly 18 years to get to the sun.
The sun doesn't seem very big to us, but it's really very huge. One million balls as big as our earth could fit inside the sun. The sun looks small because it is so far away. If the sun were much nearer, our earth would be too hot to live on. If there were no sun, the earth would be so cold that nothing could live on it. Aren't we lucky to be just about the right distance away from the sun?
The earth circles tile sun. It takes one year for the earth to go completely around. The earth spins around once every 24 hours. In the morning the sun seems to rise in the east. As the day goes on, the sun seems to travel across the sky. In the evening the sun seems to set in the west and then it is night. Almost every part of the earth turns from day to night during every 24 hours.
The sun gives us light. It keeps us warm. It makes things grow. Plants, animals and people need the sun. The sun makes our earth beautiful. We could not live with out the sun.
