[00:00.00]沪江网 CHAPTER TWO READING pages 18 and 19 COMPUTERS
[00:10.08]Tony plans to write an article about computers.
[00:17.06]This is some of the information he has collected.
[00:26.78]Not so many years ago.
[00:30.90]You hardly ever saw computers.
[00:35.94]Now they are everywhere.
[00:40.70]There may also be tiny hidden computers in your home that you are unaware of.
[00:50.13]There may be one inside your TV set, telephone or washing machine.
[00:57.78]So maybe you depend on computers more than you realize.
[01:06.04]What kind of jobs can a computer do?
[01:11.60]It is common knowledge that computers are super calculators.
[01:18.97]They can calculate very fast and rarely give wrong answers.
[01:26.91]They can also type, print and draw things like diagrams and graphs.
[01:36.97]They can teach you and play games with you.
[01:42.01]More importantly,they can operate railways
[01:47.89](like the Underground) and fly aeroplanes and spaceships.
[01:55.33]For these reasons,we often call them electronic brains
[02:03.19]Is a computer cleverer than I am?
[02:08.86]The answer to this question is,for the time being,'No'.
[02:16.72]Your brain can understand the meaning of things better and create new ideas.
[02:26.47]However,one day computers may be abl to do most things that a human brain can do
[02:35.61]and do them better.
[02:39.45]They may be better than doctors,judges and teachers at doing their jobs.
[02:49.43]If this is true,it raises interesting questions.
[02:56.98]What will happen to us if computers can do our jobs?
[03:03.82]How will we spend our lives? Will we have nothing to do?
[03:11.97]Computers may change our lives.
[03:16.44]But will they make them better?
[03:20.28]How do we give a computer instructions?
[03:25.92]We give a computer instructions by putting a program into it.
[03:34.70]The program is written by a human being,
[03:40.76]and it is essential that the human does make a mistake.
[03:48.13]If we want a computer to do different jobs,
[03:54.19]we have to give it different programs.
[04:03.41]Many of today's computers have CD-ROM drives.
[04:10.57]A CD-ROM can hold over 300,000 pages of writing,
[04:18.74]and can also contain pictures and sound.
[04:24.80]Thus,for example,you can use your computer
[04:32.17]to read about a famous person in history such as John F Kennedy
[04:39.43]and you can see a photograph or video of him,
[04:44.58]and even listen to him speaking.
[04:49.25]Some people think that CD-ROMs will soon be more popular than books.
[04:57.40]LISTENING Page 21

[11:17.20]MORE PRACTICE Page 31
[11:22.37]The History of the Internet
[11:28.01]A research team at the United States Pentagon
[11:33.58]first developed the concept of linking computers together in the 1960s.
[11:42.04]They wanted to have a system that would enable universities,
[11:49.20]research departments and the military to share resources with each other.
[11:56.77]Computers at this time were as large as refrigerators
[12:02.94]and could not be transported easily.
[12:08.19]Another problem was that they were often complicated
[12:14.43]and not compatible with each other.
[12:19.29]The research team had to overcome these difficulties
[12:24.93]to create a network that could share computing power.
[12:31.10]Gradually,more and more scholars came online.
[12:37.05]Years later, businessmen began using the Internet, too.
[12:43.53]The number of people using it is increasing all the time
[12:50.80]and it is becoming more widely available across the world.
[12:57.74]In fact,somewhere in every continent in the world,
[13:03.78]it is possible to use the Internet.
[13:08.74]There is a wide range of services available on the Internet.
[13:15.40]This means that there are many different ways to communicate.
[13:21.33]The most popular way is undoubtedly electronic mail
[13:28.10]more commonly called'e-mail
[13:32.36]The second most popular is browsing on the World Wide Web(WWW).
[13:41.71]Briefly,the WWW is a very big series of connected pages
[13:49.65]containing various forms of multimedia.
[13:54.51]The third most popular way is real time text based communication between users
[14:02.76]such as IRC-Internet Relay Chat.
