Perhaps you have heard a lot about the Internet，but what is it，do you know？The Internet is a network.It uses the telephone to join millions of computers together around the world.

Maybe that doesn't sound very interesting.But when you've joined to the Internet，there are lots and lots of things you can do.You can send e－mails to your friends，and they can get them in a few seconds.You can also do with all kinds of information on the World Wide Web(WWW)．

There are many different kinds of computers now.They all can be joined to the Internet.Most of them are small machines sitting on people's desks at home，but there are still many others in schools，offices or large companies.These computers are owned by people and companies，but no one really owns the Internet itself.

There are lots of places for you to go into the Internet.For example，your school may have the Internet.You can use it during lessons or free time.Libraries often have computers joined to the Internet.You are welcome to use it at only time.

Thanks to the Internet，the world is becoming smaller and smaller.It is possible for you to work at home with a computer in front，getting and sending the information you need.You can buy or sell whatever you want by the Internet.But do you know 98% of the information on the Internet is in English？So what will English be like tomorrow?

Today almost everyone knows computers and the Internet.If I ask you what the most important in your life is，maybe you will say“computers and the Internet”．

The first computer was made in 1946.It was very big but it worked very slowly.Today computers are getting smaller and smaller.But they work faster and faster.What can computers do？A writer has said，“People can't live without computers today.”

The Internet came a little later than computers.It is about twenty－five years later than computers.But now it can be found almost everywhere.We can use it to read books，write letters，go shopping，play games or make friends.

Many students like the Internet very much.They often go into the Internet as soon as they are free.They make friends on the Internet and maybe they have never seen these friends.They don't know their real names，ages，and even sex.They are so interested in making“unreal friends”that they can't put their heart into study.Many of them can't catch up with others on many subjects because of that.

We can use computers and the Internet to learn more about the world.But at the same time，we should remember that not all the things can be done by computers and the Internet.

文章大意：这篇文章介绍的是Internet的相关知识及介绍Internet是如何运行的，给人们带来什么好处。

1.主旨大意题。文章的每一段都谈到了Internet，所以我们可以推断文章的主要内容是Internet。

2．细节理解题。在第二段中谈到“You can send e－mails to your friends，and they can get them in a few seconds.”，相比其他选项，e－mail当然是最快的。

3．推理判断题。根据第三段最后一句并结合全文我们得知，我们可以在school，libraries，home等地方使用Internet，所以拥有者是大家，并不是某一个人或某一行业的从业者。

4．推理判断题。最后两句告诉我们：...98% of the information on the Internet is in English，也就是说英语在Internet上的应用是非常广泛、非常重要的，除A选项外，其他选项都不能全面概括这句话的意思。

B

答案：5. C    6. B    7. B    8. D

6．推理判断题。根据第二段首句“The first computer was made in 1946.”以及第三段第二句“It is about twenty－five years later than computers.”可推知。
