阅读理解。

     Being connected to the Internet has become a necessary part of modern life. Some people actually need it

as they cannot do their jobs without it, and others simply feel they need it as they cannot imagine life without it.

     To think that something that did not even exist 50 years ago has come to play a crucial role in our lives like

this in just about 15 years makes one wonder-just what will the future bring?

     In 2004, a survey was conducted in the US asking a group of technology experts their opinions on the

Internet in the next ten years. 57% of them agreed that virtual classes will be more widely adopted in schools,

allowing students to learn with those at the same level and with interests in the same subjects. It's quite possible

that, by the year 2030,every child in every school will do all their school- work on their own laptop with all

their textbooks available (现成可使用的) on the Internet. No more heavy books to carry around and no more

pens and paper!

     At work, we already use email to deal with people both inside and outside our offices and video

conferencing (电话会议) is occur- ring more frequently. This means that meetings can be held between offices

in different countries without the trouble caused by business travel. Business travel will stop to exist in the

future, and so will offices as people all start to work from home.

     It has also become a trend for people to use pocket computers such as Blackberries. With this helpful

equipment, people can send and receive emails, surf the Web, and read multimedia files from absolutely

anywhere even if we are on a beach holiday.

     The Internet will have a revolutionary (突破性的) effect on entertainment in the future. Already we can buy

and download music and movies from the Internet but it is still possible for us to buy a CD or go to the DVD

stores to rent the latest movies. However, it's quite possible that in the future, CD shops and DVD rental stores will close and cinemas will no longer exist. Entertainment will be- come completely virtual although hopefully

people will still want to get outside to play sports and entertain themselves in more healthy ways.

     With the Internet we need only relax in the rocking chair. The Internet, however, has problems to be solved.
