考博英语模拟试题



Part I Listening Comprehension(15 points) (



)


Part II Reading Comprehension (40 % )


Directions:


There are 4 reading passages in this part. Each passage is followed by some questions


or


unfinished


statements.


For


each


or


them


there


are


four


choices


marked


A,


B,


C


and


D.


You


should decide on the best choice and then mark the corresponding letter on the Answer Sheet.


Questions 16 to 20 are based on the following passage:



Eight


times


within


the


past


million


years,


something


in


the


Earth's


climatic


equation


has


changed,


allowing


snow


in


the


mountains


and


the


northern


latitudes


to


accumulate


from


one


season to the next instead of melting away. Each time, the enormous ice sheets resulting from this


continual buildup lasted tens of thousands of years until the end of each particular glacial cycle


brought a warmer climate. Scientists speculated that these glacial cycles were ultimately driven by


astronomical factor: slow, cyclic changes in the eccentricity of the Earth's orbit and in the tilt and


orientation of its spin axis. But up until around 30 years ago, the lack of an independent record of


ice- age timing made the hypothesis untreatable.



Then


in


the


early


1950's


Emirian


produced


the


first


complete


record


of


the


waxwings


and


awnings of first glaciations. It came from a seemingly odd place, the seafloor. Single-cell marine


organisms called


the foraminifera die, sink to the bottom, and become part of seafloor sediments, the carbonate of


their shells preserves certain characteristics of the seawater they inhabited. In particular, the ratio


of


a


heavy


isotope


of


oxygen


(oxygen-


18)


to


ordinary


oxygen


(oxygen


-


16)


in


the


carbonate


preserves the ratio of the two oxygen’s in wate


r molecules.



It is now understood that the ratio of oxygen isotopes reflects the proportion of the world's


water locked up in glaciers and ice sheets. A kind of meteorological distillation accounts for the


link.


Water


molecules


containing


the


heavier


isotope


tend


to


condense


and


fall


as


precipitation


slightly sooner than molecules containing the lighter isotope. Hence, as water vapor evaporated


from warm oceans moves away from its source, its oxygen - 18 returns more quickly to the oceans


than


does


its


oxygen


-


16.


What


falls


as


snow


on


distant


ice


sheets


and


mountain


glaciers


is


relatively


depleted


of


oxygen


-18.


As


the


oxygen


-18


-poor


ice


builds


up,


the


oceans


become


relatively


enriched


in


the


isotope.


The


larger


the


ice


sheets


grow,


the


higher


the


proportion


of


oxygen - 18 becomes in seawater -- and hence in the sediments





Analyzing cores drilled from seafloor sediments, Mililani found that the isotopic ratio rose


and fell in rough accord with the Earth's astronomical cycles. Since that pioneering observation,


oxygen


isotope


measurements


have


been


made


on


hundreds


of


cores.


The


combined


record


enables scientists to show that the record contains the very periodicities as the orbital processes.


Over


the


past


800,


000


years,


the


global


ice


volume


peaked


every


100,000


years,


matching


the


period


of


the


orbital


eccentricity


variation.


In


addition,



superposed


on


each


cycle


--


small decreases or surges in ice volume -- have come at intervals of roughly 23, 000 and 41,000


years, in keeping with the precession and tilt frequencies of the Earth's spin axis.


16. In opening paragraph, the author introduces his topic by________



A. unfolding a phenomenon.












B. posing a contrast.



C. refuting a speculation.
















D. testifying a hypothesis.


17. The expression



A. regularities and eccentricities.







B. vaporizations and sediments.



C. variants and constants.








D. maximizations an minimizations.


18. As pointed out in the text, the ratio of oxygen - 18 to oxygen - 16 in seafloor sediments and


that of these isotopes locked in glaciers and ice-sheets are________



A. irrelevant.




B. correlated.







C. corresponding.






D. identical.


19. Single- cell marine organisms referred to as


as_________



A. a proof against the existence of oxygen.



B. a testimony to sediment formation processes.



C. a valid record justifying glacial periodic cycles.




D. an indicator of the ratio of the t


wo oxygen’s.



20. What can we safely infer from the text?



A. Many a phenomenon might be caused by astronomical factors.



B. Any hypothesis should be abandoned unless supported by solid records.



C. Glaciers are the records keeping Earth's astronomical cycles.



D. Oxygen isotopes are evenly distributed throughout the earth surface.


Questions 21 to 25 are based on the following passage:



If you smoke and you still don't believe that there's a definite between smoking and bronchial


troubles,


heart


disease


and


lung


cancer,


then


you


are


certainly


deceiving


yourself.


No


one


will


accuse you of hypocrisy. Let us just say that you are suffering from a bad case of wishful thinking.


This


needn't


make


you


too


uncomfortable


because


you


are


in


good


company.


Whenever


the


subject of smoking and health is raised, the governments of most countries hear no evil, see no


evil and smell no evil. Admittedly, a few governments have taken timid measures. In Britain, for


example,


cigarette


advertising


has


been


banned


on


television.


The


conscience


of


the


nation


is


appeased, while the population continues to puff its way to smoky, cancerous death.



You don't have to look very far to find out why the official reactions to medical findings have


been so lukewarm. The answer is simply money. Tobacco is a wonderful commodity to tax. It's


almost


like


a


tax


on


our


daily


bread.


In


tax


revenue


alone,


the


government


of


Britain


collects


enough from smokers to pay for its entire educational facilities. So while the authorities point out


ever


so


discreetly


that


smoking


may,


conceivably,


be


harmful,


it


doesn't


do


to


shout


too


loudly


about it.



This


is


surely


the


most


short-sighted


policy


you


could


imagine.


While


money


is


eagerly


collected


in


vast


sums


with


one


hand,


it


is


paid


out


in


increasingly


vaster


sums


with


the


other.


Enormous amounts are spent on cancer research and on efforts to cure people suffering from the


disease. Countless valuable lives are lost. In the long run, there is no doubt that everybody would


be much better-off if smoking were banned altogether.



Of course, we are not ready for such drastic action. But if the governments of the world were


honestly


concerned


about


the


welfare


of


their


peoples,


you'd


think


they'd


conduct


aggressive


antismoking campaigns. Far from it! The tobacco industry is allowed to spend staggering sums on


advertising. Its advertising is as insidious as it is dishonest. We are never shown pictures of real


smokers coughing up their lungs early in the morning. That would never do. The advertisements


always depict virile, clean-shaven young men. They suggest it is manly to smoke, even positively


healthy!


Smoking


is


associated


with


the


great


open-air


life,


with


beautiful


girls,


true


love


and


togetherness. What utter nonsense!



For a start, governments, could begin by banning all cigarette and tobacco advertising and


should then conduct anti-smoking advertising campaigns of their own. Smoking should be banned


in all public places like theatres, cinemas and restaurants. Great efforts should be made to inform


young people especially of the dire consequences of taking up the habit. A horrific warning -- say,


a


picture


of


a


death's


head


--


should


be


included


in


every


packet


of


cigarettes


that


is


sold.


As


individuals we are certainly weak, but if governments acted honestly and courageously, they could


protect us from ourselves.


21. The best title of the text may be _______



A. give up the habit of smoking immediately.



B. word governments should conduct serious campaigns against smoking.



C. go on with anti-smoking lobby vigorously.



D. world governments should allocate more funds on cancer researches.


22.


As


pointed


out


in


the


text,


governments


are


reluctant


to


exercise


total


ban


on


cigarette


and


tobacco advertising _____



A. in the interests of financial rewards.








B. for the sake of the public's welfare.



C. without regard to tax collections.











D. in anticipation of smokers lobbying.


23. The word



A. dishonesty.




B. predicament.










C. indecision.







D. intimidation.


24. It can be concluded that anti-smoking campaigns should be conducted_______



A. insidiously and discreetly.















B. vividly and attractively.



C. aggressively and drastically.














D. disinterestedly and bravely.


25. The author is most critical of________



A. anti-smoking lobbyists.



















B. tobacco advertisers.



C. world governments.






















D. tax collectors.


Questions 26 to 30 are based on the following passage:



It is the staff of dreams and nightmares. Where Tony Blair's attempts to make Britain love the


Euro have fallen on deaf ears, its incarnation as notes and coins will succeed. These will be used


not just in the Euro area but in Britain. As the British become accustomed to the Euro as a cash


currency, they will warm to it paving the way for a yes note in a referendum.



The idea of Euro creep appeals to both sides of the Euro argument. According to the pros, as


Britons become familiar with the Euro, membership will start to look inevitable, so those in favor


are bound to win. According to the antis, as Britons become familiar with the Euro, membership


will start to look inevitable, so those opposed must mobilize for the fight.



Dream or nightmare, Euro creep envisages the single currency worming its way first into the


British economy and then into the affections of voters. British tourists will come back from their


European holidays laden with Euros, which they will spend not just at airports but in high street


shops. So, too, will foreign visitors. As the Earn becomes a parallel currency, those who make up


the


current


two-o-one


majority


will


change


their


minds.


From


there,


it


will


be


a


short


step


to


decide to dispense with the pound.



Nell Kinnock, a European commissioner and former leader of the Labor Party, predicts that


the Euro will soon become Britain's second currency. Hans Eichel, the German finance minister,


also says that it will become a parallel currency in countries like Switzerland and Britain. Peter


Hain, the European minister who is acting as a cheerleader for membership, says


the Euro will


become



practical


day-to- day


reality


and


that


will


enable


people


to


make


a


sensible


decision


about it


they will take Euros in some of their shops. BP has also announced that it will accept Euros at


some of its garages.



But


there


is


less


to


this


than


meet


the


eye.


British


tourists


can


now


withdraw


money


from


cash point from European holiday destinations, so they are less likely than in the past to end up


with excess foreign money. Even if they do, they generally get rid of it at the end of their holidays,


says David South well, a spokesman for the British Retail Consortium (BRC).


26. According to the writer, once the British get used to the Euro,__



A. there will be no obstacle for it to be a currency in Britain.



B. it will take the place of pound in whatever aspects in Britain.



C. the British will accept it as a cash currency gradually.



D. it will become a symbol of reunification for European countries.


27. The writer seems_________




A. to be over-enthusiastic about the success of the Euro.





B. to launch a vigorous campaign against the Euro creep.



C. to hold a hostile attitude towards Euro expansions.



D. to take a matter-of-face attitude towards the issue.


28. The word



A.








B.






C.







D.


29. What does the writer intends to illustrate with Marks and Spencer.9



A. A kind of professional service.









B. Objections to the Euro creep.



C. A type of subjective brand loyalty.






D. Expansions of the Euro in Britain.


30. Which of the following would be the best title for this passage?



A. The Prospect of the Euro in Britain.





B. A New Currency under Attack.



C. The Popularity of the Euro in Britain.




D. A Theme of Dreams and Nightmares.


Questions 31 to 35 are based on the following passage:



Whenever


you


see


an


old


film,


even


one


made


as


little


as


ten


years


ago,


you


cannot


help


being struck by the appearance of the women taking part. Their hairstyles and make-up look dated;


their skirts look either too long or too short; their general appearance is, in fact, slightly ludicrous.


The men taking part in the film, on the other hand, are clearly recognizable. There is nothing about


their appearance to suggest that they belong to an entirely different age.



This illusion is created by changing fashions. Over the years, the great majority of men have


successfully resisted all attempts to make them change their style of dress. The same cannot be


said for women. Each year a few so-called top designers' in Paris or London lay down the law and


women the whole world over msh to obey. The doctrines of the designers are unpredictable and


dictatorial. This year, they decide in their arbitrary fashion, skirts will be short and waists will be


high; zips are in and buttons are out,, Next year the law is reversed and far from taking exception,


no one is even mildly surprised.



If


women


are


mercilessly


exploited


year


after


year,


they


have


only


themselves


to


blame.


Because they shudder at the thought of being seen in public in clothes that are out of fashion, they


are annually blackmailed by the designers and the big stores, Clothes which have been worn only


a few times have to be discarded because of the dictates of fashion. When you come to think of it,


only a woman is capable of standing in front of a wardrobe packed full of clothes and announcing


sadly that she has nothing to wear.



Changing


fashions


are


nothing


more


than


the


deliberate


creation


of


waste.


Many


women


squander vast sums of money each year to replace clothes that have hardly been worn. Woman


who cannot afford to discard clothing in this way waste hours of their time altering the dresses


they have. Hem lines are taken up or let down; waist- lines are taken in or let out; neck-lines are


lowered or raised, and so on.



No one can claim that the fashion industry contributes anything really important to society.


Fashion designers are rarely concerned with vital things like warmth, comfort and durability. They


are only interested in outward appearance and they take advantage of the fact that women will put


up with any amount of discomfort providing they look right. There can hardly be a man who hasn't


at some time in his life smiled at the sight of a woman shivering in a flimsy dress on a wintry day,


or delicately picking her way through deep snow in dainty shoes.



When comparing men and women in the matter of fashion, the conclusions to be drawn are


obvious.


Do


the


constantly


changing


fashions


of


women's


clothes,


one


wonders,


reflect


basic


qualities of fickleness and instability? Men are too sensible to let themselves be bullied by fashion


designers. Do


their


unchanging


styles


of


dress


reflect


basic


qualities


of


stability


and


reliability?


That is for you to decide.


31. In the opening paragraph, the writer introduced his topic by________



A. introducing an illusion.














B. making a comparison.



C. depicting a vivid scene.















D. posing a sharp contrast.


32. In the eyes of the author, the dictates of fashion probably means a sort of design characterized


by ________



A. obsolescence and sensibility.









B. uniqueness and stability.



C. creativity and hypocrisy.













D. inconstancy and irrationality.


33. The word



A.















B.



C.












D.


34. The writer would be less critical if fashion designers placed more stress on the


_______ of


clothing.



A. suitability






B. comfort












C. appearance








D. fabric


35. It can be inferred from the passage that women should________



A. see through the very nature of fashion myths.




B. boycott the products of the fashion industry.



C. avoid following fashion doctrines too closely.





D. blame designers for their waste of money.

Directions:


There are 20 blanks in the following passage. For each blank there are four choices


marked A, B, C and D. You should choose the ONE that best fits into the passage. Then mark the


corresponding letter on the Answer Sheet.



Every second,



56



hectare of the world's rainforest is destroyed. That's one to two football


fields.



This




57



rate of destruction has serious consequences



58



the environment. Scientists


estimate, for example, that 137




59



of plant, insect or animal become




60



every day due to


logging. In British Columbia,



61



, since 1990,thirteen rainforest valleys have been clear cut,


142 species of salmon have already become extinct, and the




62



of grizzly bears, wolves and


many


other


creatures


are


threatened.


Logging,





63



,


provides


jobs,


profits,


taxes


for


the


government and cheap products of all kinds for consumers, so the government is




64



to restrict


or control it. Much of Canada's forestry production

forests could be



67


. Recently, a possible



68



way of producing paper has been suggested by


agriculturalists


and


environmentalists:


a

cultivated


by


many


cultures


for


thousands


of


years.


It

and


pulp.


According to its proponents, four-times as

Part V Translation from English into Chinese


Directions:



Translate


the


following


passage


into


Chinese,


and


then


write


it


on


the


ANSWER


SHEET.



What,


then,


does


Drucker


suggest


are


the


new


knowledge-based


industries


on


which


economic growth will depend? He discusses three categories of such industries. The first of these


is


the


information


industry.


This


industry


collects,


stores,


spreads,


and


applies


knowledge.


It


depends on the computer. In the future, however, the computer itself will probably become less


important than communicating and applying knowledge. Dmcker foresees a central computer that


will make information available to everyone. Another source of new industries is the science of


the oceans. New technologies may help to supply food and minerals from the seas. A third new


source


of


economic


growth


is


the


materials


industry.


This


industry


provides


the


materials


for


making objects. One such industry that has already become economically important is the plastic


industry. Dmcker explains that throughout history our traditional materials have been metals, glass,


natural fibers, and paper. Today, with the help of modem science, industries can make many new


materials to meet specific needs. Because they will be created to fit a certain product, they will be


highly efficient. Consequently, he points out, industries that supply traditional materials such as


steel or glass Will have trouble competing with those that produce these new materials.
