M:Professor,what exactly is your goal?Why do you do all of this?

W:Well,as you said,I do have different thing going on.But these,I think,can be divided into two roups:the education of sciemce and the further understandin of science.

M:Don't these two things get in the way of each other?What I meam is,doesn't giving lectures take time away from the lab?

W:Not really,no.I love teaching.and I don't mind spending more time doing that now than in the past.Also,what  I will sa is that teachin a subect hel s me com rehend it better m self.I find that it furthers my own knowledge when I have to explain something clearly,when I have to aid others in understanding it,and when I have to answer questions about it.Teaching at a high level can bevery stimulating for anyone,no matter how much expertise  they may already have in the field they are instructing.

M:Are there any scientific breakthroughsthat you see on the near honizom,asignificant discovery or invention we can expect soon?

W:The world is always conducting science,and there are constantly new things being discovered.In fact,ri ht now we have too much data sittin in com uters.For example,we have thousandsof photos of planet Mars taken by telescopes that nobody has everseen.We have them,yet nobody has had time to look at them with their own e es,let alone anal ze them.

Questions 5 to 8 are based on the conversation you have just heard.

M:Do you think dreams have special meanings? 

W:No,I don't think they do.

M:I don't,either.But some people do.I would say people who believe that dreams have specia meanings are superstitious,especially nowadays.In the past,during the timesof ancient Egypt.Greece,or China,people used to believe that dreams could foresee the future.But today.with all the scientific knowledge that we have.I think it's much harder to believe in these sortsof things.

W:My grandmother is superstitious,and she thinks dreams can predict the future.Once she dreamed that the flight she was due to take the following daycrashed.Can youguess what she did?She didn't take that flight.She didn't even bother to go to the air port the followingday.Instead,she took the same flight,but aweeklater.And everything was fine,of course.No plane ever crashed.

M:How funmy!Did you know that flying is actually safer than any other mode of transport?It's been statistically provem.People can be so irrational sometimes.

W:Yes,absolutely.But even if we think they are ridiculous,emotions can be just as powerful as rational thinking.

M:Exactly.People do all sorts of crazy things because of their irational feelins.But in fact,some psychologists believe that ourdreams are the result ofour emotions and memories from that day.I think it was Sigmund Freud who said that children's dreams were usually simple representations of their wishes,things they wished would happen.But in adults,dreams are much more complicated reflections of their more sophisticated sentiments.

W:Isn't it interesting how psychologists try to understand,using the scientificmethod,something ias bizarre as dreams?Psychology is like the rational study of irrational feelings.

Section B

Questions 9 to 11 are based on the passage you have just heard.

While some scient sts explore the surface of Antarctica,others are learning more about a giant body of water four kilometers beneath the ice pack.Scientists first dicovered Lake Vostok in the 1970s by using radio wavesthat penetrate the ice.Since then they have used sound waves and even satellites to map this massive body of water.

How does the water in LakeVostok remain liquid beneath an ice sheet?The thick glacier above actslike an insulating blanket andkeepsthe water from freezing,says Martin Siegert,a glaciologist from the University of  Wales.In addition.geothermal heat from deep within the Earth may warm the hidden lake.The scientists suspect that micro or sanisms may be livingin Lake Vostok,closed off from the outside world for more than two million years.Anything found there will be totally alien towhat's on the surface of the Earth,saysSiegert.Scientists aretrying to find a way to drill into the ice and draw water samples without causing contamination.

Again,robots might bethe solution.If all goes as planmed,a drill shaped robot will melt through the surface ice.When it reaches the lake,it will release another robot that canswim in the lake,take picturesand look for  signs of life.The scientists ho e their discoveries will shed li ht on life in outer s ace which mi ht exist in similar dark and airles conditions.Recently,closeup picturesof Jupiter's moon Europa showed signs of water beneath its icy surface.Once tested in Antarctica,robots could be sent to Europa to search for life there,too.

The idea to stud the American Indian tribe Tarahumaras came to James Co eland in 1984 when he discovered that ver little research had been done on their lan ua e.Hecontacted a tribe member through a social worker who worked withthe tribesmen in Mexico.At first,the tribe member named Gonzalezwasvery reluctant to cooperate.He told Copeland that no amount of money could buy his language.But after Copeland explained tohim what he intended todo with his researchand howit would benefit the Tarahumaras,Gomzalez agreed to help.He took Co eland to his villa e and served as an intermediar .Copeland says.“Thanks to him,the Tarahumarasunderstood what our mision was and started trusting us.”Entering the world of the Tarahumaras has been a laborious ro ect forCo eland.To reach their homeland,he must drive two and a half days from Houston,Texas.He loads up his vehicle with goods that the tribesmen can'teasily get and gives the goods to them as agesture of friendship.TheTarahumaras,who don'tbelieve in acumulating wealth,take the food and share it among themselves.

For Copeland,the experience has not only been academically satisfying 。but also has enriched his life in  several ways.“I see people rejecting technology and living a very hard,traditional life,which offers me another notion about the meaning of progress in the Western tradition,"he says.“I experienced the sim licit of livin in nature that I would otherwise oml be able to read about.I see a lot of beaut in their sense of sharing and concern foreach other.”

Section C

Questions 16 to 18 are based on the recording you havejust heard.

What is a radical?It seems today that people are terrifed of the term,particularly of having the label atached to them.Accusing individuals or groups of being radical often serves to silence them into submission,thereby maintaining the existing state of affairs,and,more important,preserving the power of a select minority who are mostly wealthy white males in Westernsociety.

Feminism is a perfect example of this phenomenom.The women's movement has been plagued by stereotypes,misrepresentations by the media andaccusations of man hating and radicalism,when the basic  foundation of feminismis simply that women deserve equal rights in allfacets of life.When faced with a threat  of being labelled radical,women backdown from their worthy cause and consequently participate in theirown  oppressiom.It has gotten to the point that many women are afraid to call themselves feminists because of the stigma attached to the word.If people refuseto be controlled and intimidated by stigmas,the stigmas lose all  their power.Without fear on which they feed,suchstigmas can only die.

To me,a radical is simply someone who rebels against the nom while advocates a change in the existing state of affairs.On closer inspection,it becomes clear that the norm is constantly evolving and therefore is not a constant entity.So why then is deviation from the present situationsuch a threat when the state of affairs itself is unstable and subject to relentless transformatiom?It all goes back to maintaining the power of those who have it and preventing the rights of those who don't.In fact,when we look at the word"radical"in a historical context,nearly every figure we now hold up as a hero wasconsidered a radicalin his or her time.Radicals are people who effect change.Theyare the people about whom history is written. Abolitionists were radicals;civil rights activists were radicas;even the founders ofour country in their fight to win  independence from England were radicak.Their presence in history has changed the way our society  functions,mainly by shifting the balance of power that previously existed.Of course,there are someradicas  who've made a negative impact on humanity.But undeniably,there would simply be no progress without  radical.That being said,next time someone calls me a radical,I will accept that label with pride.

16.What usually happens when peopleare accused of being radical?

17.What is the speaker's definition of a radical?

18.What does the speaker think of most radicas in the American history?

Questions 19 to 21 are based on the recording you havejust heanl.

We are very susceptible to the influence of the people around us. For instance,you may have known somebody who hasgone overseas for a year or so,and has returned with an accent,perhaps.We becomepart of our immediate emviromment.None of us are immume to the influences of our own world.And let us not kid ourselves that we are untouched by the things and the people in our life.Fred goes off to his new job at a factory.Fred takes hs 10 minute coffee break,but the other workers take a half an hour.Fred says,“What's thematter with you guys?”Two weeks later,Fred is taking 20 minute breaks.A month later,Fred takes his half hour.Fred is saying,“If you can't beat them,join them.Why should I work any harder than the next guy?”

The fascinating thing about being human is that generally we are unaware that there are changes taking place in ourmentality.It is like returningto the city smog after some weeks in the fresh air.Only then do we realise that we have becomeaccustomed to the nasty smells.Mix with critical peopleand we learn to criticize.Mixwith happy people andwe learn about happines.What this meansis that weneed to decide what we want fromlife and then chooseour company accordingly.You may well say,“That is going to take some effort.It may not be comfortable.I may offend some of my present company.”Right!But it is your life.Fred may say,“I'm always broke,frequently depressed.I'm going nowhere and I never do anything exciting.”Then we discovered that Fred's best friends are always broke,frequently depressed,going nowhere and wishing that life was more exciting.This is not coincidence,nor is it our business to stand in judgement to Fred.However,if Fred ever wants to im rovehis ualit of life,the first thin he'll need to do is reco nise what has been oin on all these years.It's no surprise that doctors as a profession suffer a lot of ill health because they spend their lives around sick people.Ps  chiatrists have a hi her incidence of suicide in their profesion for related reasons.Traditionally,nine out of ten children whose parents smoke,smoke themselves.Obesity is in part an envirommental problem.Succesful people have succesful friends.And so the story goes on.

19.What does the speaker say about us as human beings?

20.What does the speaker say Fred should do first to improve his quality of life?

21.What does the speaker say about psychiatrists?

Virtuall ever Americancan reco mize a dollarbill at a mere lance.Man can identif it bits sound or texture.But few eo le indeed can accuratel describe the world's most owerful,imortant currency.

The American dollar bill is colored with black ink on one side and green on the other.The exact com osition of the a er and ink is a closel arded overnment secret.Despite its weighty importance,the dollar bill actually weighs little.It requires nearly 500 bills to tip the scales at a pound.Not only is the dollar bill lightweight,but it abo has a brief lifespan.Few dollar bills survive longer tham 18 months.

The word“dollar"is taken from the German word“thaler,"the name for the world's most important currency in the 16th century.The thaler was a silver coin first minted in 1518 under the reign of Charles V, Fmperor of Germamy.

The concept of paper money is a relatively recent innovation in the history of American currency.When the  Constitution was signed,people had little regard for paper money because of its steadil decreasing value during the colonial era.Because of this lack of faith,the new American government minted only coins for common currency.Interest bearing bank notes were issued at the same time,but their purpose was limied to providing money for urgent government crises,such asAmerican involvement in the War of 1812.The first noninterest bearing paper currency was authorized by Congress in 1862,at the height of the Civil War.At this point,citizens'old fears of devalued papercurrency had calmed and the dollarbill wasborn.The new green colored papermoneyquickly earned the nickname“greenback.”

Today,the American dollar bill is a product of the Federal Reserve,and is issued from the 12 Federal Reserve banks around the United States.The government keeps a steady supplyof approximately two billion bills in circulation at all times.Controversy continues to surround the true value of the dollar bill American history has seen generations of politicians argue in favor of a gold standard for American currency.However,forthe  present,the American dollar billholds the value that is printed on it,and little more.The onlyother guarantee on the bill is a Federal Reserve pledge as a confirmation in the form of government securities.

22.What does the speaker say about the American dollar bill?

23.What does the speaker say about the exact composition of the American dollar bill?

24.Why did the new American government mint only coins for common currency?

25.What have generations of American politicians argued for?
