　　You’ve probably heard of a lot about the Internet, but what is it?

　　The Internet is a computer network that uses the telephone system to connect together millions of computers around the world．

　Maybe that isn’t very exciting but once you’re connected to the Internet, there are lots and lots of different things you can do．You can send electronic messages or “emails” to your friends(as long as they’re on the Internet, too), or you can sort through all kinds of information on something called the World Wide Web(www世界信息网)．

　　You don’t need to know how the Internet works in order to use it, but if you understand the basics, it may help you work out any technical problems you have－and of course you can help your friends with your Net knowledge!

　　You may think that your telephone is just for talking．But as long as you have the equipment, you can use a telephone line to send computer data(数据)as well as sounds．If you connect your computer with the telephone system, it can receive information from, and send information to other computers(as long as they are connected with the telephone system, too)．

　　Because there is not an organization which operates the Internet, no one exactly knows how many people are connected to it．It’s thought that there could be 60 millionpeople on the Net, connected up to over 15 million computers!

　　I opened the box．There was a beautiful gold ring in it．So I went 　　5　　 to the police station．

　　“Has anyone lost a ring?” I asked．“Yes,” said a policeman．“A young man who came in this morning lost a ring．He lost it in London．” He 　　6　　 the young man．A few minutes later, the man arrived．“Yes, this is my ring,” he said．“How can I thank you, sir?You see, I paid a lot of money for this ring and 　　7　　 I lost it on the train!”

　　You’ve probably heard a lot about the Internet, but what is it?

　　The Internet is a computer network that uses the telephone system to link together millions of computers around the world．

　　Maybe that doesn’t sound exciting, but once you’re connected to the Internet, there are lots and lots of different things you can do．You can send electronic messages or “E-mail” to your friends(as long as they’re on the Internet too), or you can sort(挑出, 拣出)through all sorts of information on something called the World Wide Web．

　　You don’t need to know how the Internet works in order to use it, but if you understand the basics, it may help you solve any technical problem you have－and of course you can impress your friends with your Net knowledge!

　　You may think that your telephone is just for talking．But as long as you have the right equipment, you can use a telephone line to transmit computer data(数据)as well as sounds．If you plug your computer into the telephone system it can receive information from and send information to other computers(as long as they are plugged into the telephone system too)．

　　Computer data is made up of electronic signals(讯息)．A computer language called TCP/IP

　　(which stands for Transmission Control Protocol/Internet Protocol, if you like to know these things)is used to move computer data around the Internet．Many of the links, for example, those which send out computer data across the Atlantic Ocean, are special fiber optic cables(光导纤维电缆),

　　fiber optic cables use light to send out information．They can carry a lot more data than an ordinary telephone line and they send it a lot faster!
