7、nfant school is the teachers affair.It is up to the teacher to see that such a child is given more advanced reading material.Similarly,the child who still cannot read by the time he goes to junior school at the age of seven should be given every help by teachers and parents alike.They should make ce

8、rtain that he is not dyslexic*.If he is,specialist help should immediately be sought.n Although parents should be careful not to force youngsters aged two to five to learn to read(if badly done it could put them off reading for life)there is no harm in preparing them for simple recognition of letter

10、d be undertaken gently,with great patience and a sense of humour.Reading should never be made to look like a chore and the child should never be forced to continue,should his interest start to flag*.Part 1 Sentence Identificationn1.Sn2.C-Cn3.CPn4.Sn5.CPLTapescriptn1.The line down the middle of the r

17、now what I mean.Why is the sound quality so good?I mean,why do CDs sound so much clearer than cassette tapes?KATHY:Actually,I do know that.MIKE:Really?KATHY:Its all based on digital sound.CDs are digital.Digital sound is like several photos,all taken one after another.Its kind of like pictures of so

18、und.The intensity of the sound how strong it is-is measured very quickly.Then its measured again and again.When we hear the sound,it all sounds like one long piece of sound,but its really lots of pieces close together.And each piece is really clear.M1KE:So digital is like lots of short pieces of sou

19、nd.KATHY.Exactly.This is different from analog*-thats how they used to record.Analog is more like one wave of sound.It moves up and down with volume and pitch.Anyway,analog is like a single wave.Digital is like a series of pieces.MIKE:OK,I understand that.But how do they make the CDs?KATHY:I told yo

20、u.They get a hunch of musicians together,and they sing and play.MIKE:OK,I understand that.But how do they make the CDs?KATHY:I told you,Mike.They get a bunch of musicians together,and they sing and play.MIKE:Kathy!KATHY:No.What really happens is first they do a digital recording-on videotape.MIKE:On

21、 videotape.KATHY:Yeah,they use videotape.So then the videotape is played through a computer.MIKE:OK.What does the computer do?KATHY:Well,the computer is used to figure out the pieces of sound we were talking about;how long everything is,how far apart spaces are.MIKE:OK.So the computer is figuring ou

22、t those separate pieces of sound.KATHY:Yeah.They need to do that to make the master.MIKE:The master?KATHY:The master is the original that all the other CDs are copied from.Its made of glass.Its a glass disk that spins around-just like a regular CD.And the glass disk is covered with a chemical.They u

23、se a laser to bum the signal,or the song,into the glass plate.The laser burns through the chemical,but not through the glass.MIKE:So the laser cuts the sound into the plate.KATHY:Right.What its doing is cutting little holes.into the back of the disk.Those holes are called pits.The laser puts in the

24、pits.MIKE:So CDs really have little holes on the back?I didnt know that.KATHY:Yeah.Tiny pits.Theyre too small to see.Pause.Anyway,then theyve got the master,and they make copies from it.Then you buy your copy and put it in the CD player.MIKE:Put it in the CD player.That part I understand.KATHY:There

25、s another laser in your CD player.The light of the laser reflects off the CD.The smooth part of the CD reflects straight back,like a mirror.But the light that bounces off the pits is scattered.Anyway,the computer in your CD player reads the light that bounces off the pits.And you get the music.MIKE:

26、Reflected light,huh?.Uh.you knew what I like?Just relaxing,listening to music,and not really worrying about how it gets on the disk.KATHY:You want me to explain it again?MusicDialogue 2 Lost in TranslationProductadvertisedDescription of the adMessageMistake madedetergentshirtgasIn the ad there was a

27、 pile of dirty clothes on the left,a box of the laundry soap in the middle,and a pile of clean clothes on the right.This detergent would make really dirty clothes clean.In the Middle East,they should have changed the order of the pictures.When I wore this shirt,I felt good.They made a translation mi

29、th a pile of dirty clothes on one side and then the same clothes after theyve been washed?Sure.Man:There was an American company that had one of those ads.It was really successful in North America.In the ad there was a pile of dirty clothes on the left,a box of the laundry soap in the middle,and a p

30、ile of clean clothes on the right.So,the message was that a box of this detergent would make really dirty clothes clean.Woman:Yeah?Man:So what do you think happened when they used the ad in the Middle East?Woman:I dont know.Man:Think about it.In the Middle East,languages are written from right to le

31、ft.People look at things from right to left.Woman:So it looked like the soap made the clothes dirty?Man:“Our soap will make your clothes dirty!”Not a very smart ad campaign.Woman:They should have changed the order of the pictures.They should have put the picture of the clean clothes on the left side

32、 and the dirty clothes on the right.Man:Really,Oh,heres another one.Some shirt maker put an ad in a Mexican magazine.Woman:And?Man:Well,the ad was supposed to say,“When I wore this shirt,I felt good.”But they made a translation mistake.Woman:What did they say?Man:Instead of“When I wore this shirt,”t

33、he ad said,“Until I wore this shirt,I felt good.”Woman:“Until I wore this shirt,I felt good?”Gee,changing one little word gave it the opposite meaning.Man:The article says sometimes its not just the advertising slogan that gets companies into trouble.Sometimes the company name can scare off business

34、.Woman:What do you mean?Man:Well,there was a large oil company in the United States called Enco:E-N-C-O.Woman:Yeah,I remember them.Man:They opened some gas stations in Japan,and they advertised using their American name.Unfortunately,they didnt know what the word means in Japanese.Woman:What does it

35、 mean?Man:“Enco”is a short way of saying“Engine stop”in Japanese.Woman:Great.Would you buy gasoline from a company that said your car engine would stop?Man:No,and neither did the Japanese.Part 2 PassageToothbrushPre-listening:First,the toothbrush was made of hairs from the neck of a Siberian wild bo

40、ygiene!We know this today because they also had the good habit of being entombed*with all their treasures.So we were able to discover that tombs from 3,000 years before Christ contained small tree branches whose ends had been frayed*into soft fibers.Its comical to imagine an Egyptian stopping to bru

41、sh his teeth after a meal,on his break from building a pyramid!The true ancestor of our toothbrush,however,was invented by the Chinese in the 15th century and brought back to Europe by travelers.This toothbrush was made of hairs from the neck of a Siberian wild boar which were fixed to a bamboo or b

42、one handle.The people of the Occident*,however,found the wild boar hairs too stiff.At the time,very few people in the Western world brushed their teeth,and those who did preferred horse hairs,which were softer than those of the wild boar!In Europe,it was more customary after meals to use a goose fea

44、ntury!Script In 1937,in the Du Pont laboratories in Nemours,U.S.,nylon was invented by Wallace H.Carothers.In 1938,this new material became a symbol of modernism and prosperity through the commercialization of nylon stockings and of Dr.Wests miracle toothbrush with nylon bristles.The wild boars were

45、 finally off the hook!At first,even if there were many advantages to using this new brush instead of the one made with wild boar hairs(which fell out,wouldnt dry very well or became full of bacteria),the consumers were not entirely satisfied.This is because the nylon bristles were very stiff and hur
