1Part II Reading Comprehension35 minutes)Directions:There are 4 passages in this part.Each passage is followed by some questions orunfinished statements.For each of them there are four choices marked A),B),C)and D).You should decide on the best choice and mark the corresponding letter onthe Answer Sheet with a single line through the center.Passage OneQuestions 21 to 25 are based on the following passage.The biggest safety threat facing airlines today may not be a terrorist with a gun,but the manwith the portable computer in business class.In the last 15 years,pilots have reported well over100 incidents that could have been caused by electromagnetic interference.The source of thisinterference remains unconfirmed,but increasingly,experts are pointing the blame at portableelectronic device such as portable computers,radio and cassette players and mobile telephones.RTCA,an organization which advises the aviation (industry,has recommended that allairlines ban (such devices from being used during "critical"stages of flight,particularlytake-off and landing.Some experts have gone further,calling for a total ban during all flights.Currently,rules on using these devices are left up to individual airlines.And although someairlines prohibit passengers from using such equipment during take-off and landing,most arereluctant to enforce a total ban,given that many passengers want to work during flights.The difficulty is predicting how electromagnetic fields might affect an aircraft's computersExperts know that portable device emit radiation which affects those wavelengths which aircraftuse for navigation and communication.But,because they have not been able to reproduce theseeffects in a laboratory,they have no way of knowing whether the interference might be dangerousor not.The fact that aircraft may be vulnerable(易受损的)to interference raises the risk thatterrorists may use radio systems in order to damage navigation equipment.As worrying,though,isthe passenger who can't hear the instructions to tum off his radio because the music's too loud.21.The passage is mainly aboutA)a new regulation for al airlinesB)the defects of electronic devicesC)a possible cause of aircraft crashesD)effective safety measures for air flight22.What is said about the over 100 aircraft incidents in the past 15 years?A)They may have been caused by the damage to the radio systems.B)They may have taken place during take-off and landing.C)They were proved to have been caused by the passengers'portable computers.D)They were suspected to have resulted from electromagnetic interference.23.Few airlines want to impose a total ban on their passengers using electronic devices becauseA)they don't believe there is such a danger as radio interferenceB)the harmful effect of electromagnetic interference is yet to be provedC)most passengers refuse to take a plane which bans the use of radio and cassette playersD)they have other effective safety measures to fall back on24.Why is it difficult to predict the possible effects of electromagnetic fields on an airplane'scomputers？A)Because it is extremely dangerous to conduct such research on an airplane.B)Because it remains a mystery what wavelengths are liable to be interfered with.C)Because research scientists have not been able to produce the same effects in labs.D)Because experts lack adequate equipment to do such research.25.It can be inferred from the passage that the authorA)is in favor of prohibiting passengers'use of electronic devices completelyB)has overestimated the danger of electromagnetic interferenceC)hasn't formed his own opinion on this problemD)regards it as unreasonable to exercise a total ban during flightPassage TwoQuestions 26 to 30 are based on the following passage.The rise of multinational corporations(跨国公司)，global marketing,new communicationstechnologies,and shrinking cultural differences have led to an unparalleled increase in globalpublic relations or PR.Surprisingly,since modern PR was largely an American invention,the U.S.leadership inpublic relations is being threatened by PR efforts in other countries.Ten years ago,for example,the world's top five public relations agencies were American-owned.In 1991,only one was.TheBritish in particular are becoming more sophisticated and creative.A recent survey found thatmore than half of all British companies include PR as part of their corporate planningactivities,compared to about one-third ofU.S.companies.It maynot be long before London replaces New York as the capital of PR.2Why is America lagging behind in the global PR race?First,Americans as a whole tend to befairly provincial and take more of an interest in local affairs.Knowledge of world geography,forexample,has never been strong in this country.Secondly,Americans lag behind their Europeanand Asian counterparts(相对应的人)in knowing a second language..Less than5 percent ofBurson-Marshall's U.S.employees know two languages.Ogilvy and Mather has about the samepercentage.Conversely,some European fimms have half or more of their employees fluent in asecond language.Finally,people involved in PR abroad tend to keep a closer eye on internationalaffairs.In the financial PR area,for instance,most Americans read the Wall Street Journal.Overseas,their counterparts read the Joumal as well as the Financial Times of London and TheEconomist,publications not often read in this country.Perhaps the PR industry might take a lesson from Ted Turner of CNN(Cable News Network).Turner recently announced that the word "foreign"would no longer be used on CNN newsbroadcasts.According to Tumer,global communications have made the nations of the world sointerdependent that there is no longer any such things as foreign.26.According to the passage,U.S.leadership in public relations is being threatened because ofA)an unparalleled increase in the number of public relations companiesB)shrinking cultural differences and new communications technologiesC)the decreasing number of multinational corporations in the U.S.D)increased efforts of other countries in public relations27.London could soon replace New York as the center of PR becauseA)British companies are more ambitious than U.S.companiesB)British companies place more importance on PR than U.S.companiesC)British companies are heavily involved in planning activitiesD)four of the world's top public relations agencies are British-owned28.The word“provincial”Line2,Para.3)most probably means“A)limited in outlookB)like people from the provincesC)rigid in thinkingD)interested in world financial affairs29.We leam from the third paragraph that employees in the American PR industryA)speak at least one foreign language fluentlyB)are ignorant about world geographyC)are not as sophisticated as their European counterpartsD)enjoy reading a great variety of English business publications30.What lesson might the PR industry take from Ted Turner of CNN?A)American PR companies should be more internationally-minded.B)The American PR industry should develop global communications technologies.C)People working in PR should be more fluent in foreign languages.D)People involved in PR should avoid using the word"foreign".Passage ThreeQuestions 31 to 35 are based on the following passage.Brazil has become one of the developing world's great successes at reducing populationgrowth-but more by accident than design.While countries such as India have made joint efforts toreduce birth rates,Brazil has had better result without really trying,says George Martine atHarvard.Brazil's population growth rate has dropped from 2.99%a year between 1951 and 1960 to1.93%a year between 1981 and 1990,and Brazilian women now have only 2.7 children onaverage.Martine says this figure may have fallen still further since 1990,an achievement thatmakes it the envy of many other Third World countries.Martine puts it down to,.among other things,soap operas(通俗电t视连续剧)and installment(分期付款)plans introduced in the 1970s.Both played an important,,although indirect,role inlowering the birth rate.Brazil is one of the world's biggest producers of soap operas.Globo,Brazil's most popular television network,shows three hours of soaps six nights a week,whilethree others show at least one hour a night.Most soaps are based on wealthy characters living thehigh life in big cities."Although they have never really tried to work in a message towards the problems ofreproduction,they describe middle and upper class values-not many children,different attitudestowards sex,women working,"says Martine."They sent this image to all parts of Brazil and madepeople conscious of other pattems of behavior and other values,which were put into a veryattractive package..”Meanwhile,the installment plans tried to encourage the poor to become consumers."This ledto an enormous change in consumption patterns and consumption was incompatible(不相容的)with unlimited reproduction,"says Martine.31.According to the passage,Brazil has cut back its population growthA)by educating its citizensB)by careful family planningC)by developing TV programmesD)by chance32.According to the passage,many Third World countriesA)haven't attached much importance to birth controlB)would soon join Brazil in controlling their birth rateC)haven't yet found an effective measure to control their populationD)neglected the role of TV plays in family planning
