　　[00:05.69]Before listening to each one,you will have time to read

[00:10.14]the questions related to it.

[00:13.90]While listening,answer each question by choosing A,B,C or D.

[00:20.24]After listening,

[00:23.41]you will have time to check your answers

[00:27.38]You will hear each piece once only.

[00:32.03]Questions 11~ 13 are based on the following talk about the Internet.

[00:38.69]You now have 15 seconds to read Questions 11-13.

[00:44.54]M:The Internet is a vast network of computers that

[00:50.86]connects many of the world's businesses,institutions,and individuals.

[00:56.74]The Internet,which means interconnected network of networks,

[01:02.30]links tens of thousands of smaller computer networks.

[01:07.34]These networks transmit huge amounts of information in the

[01:12.91]form of words,images,and sounds.

[01:17.35]The Internet has information on virtually every topic.

[01:22.10]Network users can search through sources ranging from vast databases

[01:28.76]to small electronic "bulletin boards",

[01:33.44]where users form discussion groups around common interests.

[01:39.00]Much of the Internet's traffic

[01:42.35]consists of messages sent from one computer user to another.

[01:47.91]These messages are called electronic mail or e-mail.

[01:53.16]One feature of the Internet provides graphics,audio,and video

[01:59.01]to enhance the information in its documents.

[02:03.48]These documents cover a vast number of topics.

[02:08.21]People usually access the Internet with a device called a modem 1.

[02:13.64]Modems connect computers to the network through telephone lines.

[02:19.89]Much of the Internet operates through worldwide

[02:24.43]telephone networks of fiber-optic cables.

[02:29.29]In the future,

[02:32.14]the Internet will probably grow more sophisticated as

[02:37.10]computer technology becomes more powerful.

[02:41.46]Many experts believe the Internet may become part of a larger network

[02:47.21]called the information superhighway.

[02:51.57]This network,

[02:54.63]still under development,would link computers with telephone companies,

[03:00.19]cable television stations,and other communication systems.

[03:06.36]Questions 14-16 are based on the following lecture on Five Senses of Man.

[03:14.82]You now have 15 seconds to read Questions 14--16.

[03:21.48]W:Everyone talks about the "five" senses of man.

[03:28.82]And it's true that we get our information about the

[03:33.26]outside world from our sense of sight,hearing,smell,touch and taste.

[03:39.61]Researchers tell usthat the sense of sight--our visual sense --gives us

[03:45.67]up to 80% of what we know about the world outside our bodies;\

[03:51.52]while the other senses the hearing,the smell,the touch,and the taste

[03:57.19]bring into our brains information about the other

[04:01.84]twenty percent of what is happening.

[04:05.79]But there are,two other senses that we cannot get along without,

[04:11.35]though they are very seldom given any credit for helping 2 us

[04:16.31]to survive in this difficult world.

[04:20.68]These are:the sense of balance,and the kinesthetic sense.

[04:26.42]The sense of balance without which,we would act like a drunk,

[04:31.70]is located in the inner ear.

[04:35.36]The inner ear contains three curved tubes,filler with liquids.

[04:42.02]The shifting of these liquids,activates nerve endings in the linings 3 of the canals

[04:48.57]and nerve impulses from these nerve endings help our brains to keep us upright.

[04:55.94]The kinesthetic sense is actually made up of nerve impulses

[05:01.53]that arise from nerves planted in close contact with our muscles.

[05:07.46]These nerve messages,

[05:10.91]are constantly telling us what position our limbs,

[05:16.08]trunk and head are in.

[05:19.32]They serve as a continuous "feedback" system to

[05:24.28]help us know how to move our various parts and when to hold them still.

[05:30.63]Otherwise,we would lack the coordination 4 to run,jump,

[05:35.39]dance the twist,or even sit still.

[05:40.14]Incidentally the word "kinesthetic"

[05:44.08]comes from two Greek words meaning "motion" and "feeling".

[05:50.04]The kinesthetic sense gives our ideas about our own motion.

[05:56.52]Questions 17 - 20 are based on a conversation about Entertainments.

[06:03.08]You now have 20 seconds to read Questions 17- 20.

[06:08.64]W1:In China

[06:14.10]I think that a lot of people have the idea that there's always

[06:19.66]plenty going on in the west,always lots to do in one's

[06:24.99]spare time,is that in fact true?

[06:28.96]M:Hmm...yes...in Britain it's true,

[06:33.51]especially in London and the other big cities.

[06:37.95]In small towns though it can sometimes be a bit dull.

[06:42.70]What about the States,Elen?

[06:46.86]W2:Yeah...things are pretty lively there too in the larger places.

[06:52.71]If you have the time and the money to get to a city there's

[06:57.36]always somewhere to go once you get there.

[07:01.93]W1:OK...but what do people actually do for entertainment?

[07:07.39]For example in Britain what sorts of entertainments are actually popular?

[07:12.85]M:Er...I suppose that some of the most popular

[07:17.60]forms of entertainment for everyone are the cinema and watching TV

[07:23.35]Adults go out to pubs to meet friends,have a drink and maybe play darts 5 or pool

[07:30.61]er...increasingly going out to eat is becoming a sort o entertainment and mmm.

[07:37.98]for younger people going to discos or

[07:42.24]to live pop or rock concerts is pretty popular too.

[07:47.59]W1:How about the U.S.?

[07:50.83]W2:I guess the number one form of entertainment

[07:55.79]for almost everybody has to be the TV and the radio.Mmm...

[08:00.97]after that er...yeah going to see a film and going out to eat,

[08:07.52]maybe going to a drive-in movie theatre and a drive-in restaurant;

[08:13.37]that would be a very American way to spend the occasional evening

[08:19.23]especially in a smaller town.

[08:23.30]M:Yeah,that's an amazing experience for somebody from Britain,

[08:28.76]we've got nothing like it.

[08:32.00]W2:and er...we go to bars to drink and

[08:37.33]meet friends and well in the larger places yes...going to clubs and discos

[08:44.80]W1:But what about live performances,the theatre,ballet,the opera?

[08:50.76]Neither of you have mentioned those.

[08:54.80]W2:Well...they exist of course...There's Broadway in New York where there

[09:00.73]are always a couple of dozen shows,and er...

[09:05.72]most bigger cities have one or

[09:09.67]two theatres,often connected to the local university and

[09:15.02]these sometimes present ballet and opera too.

[09:20.48]Mmm...the trouble is...er...that often the tickets are very expensive,

[09:28.95]especially if it's a first-rate company performing,

[09:34.01]so it's often the older,richer people who go rather than ordinary people.

[09:40.68]It's not really something that everybody does.
