[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 modem1.
[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 helping2 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 linings3 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 coordination4 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 darts5 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.
