Reading Comprehension

　　Direction: There are 4 passages in this part. Each passage is followed by some questions or unfinished 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 on the Answer Sheet with a single line through the center.

　　Passage One

　　Questions 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 man with the portable computer in business class. In the last 15 years, pilots have reported well over 100 incidents that could have been caused by electromagnetic interference. The source of this interference remain s unconfirmed, but increasingly, experts are pointing the blame at portable electronic device such as portable computers, radio and cassette players and mobile telephones.

　　RTCA, an organization which advises the aviationindustry, has recommended that all airlines bansuch devices from being used during critical stages of flight, particularly take-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 some airlines prohibit passengers from using such equipment during take-off and landing, most are reluctant to enforce a total ban, given that many passengers want to work during flights.

　　The difficulty is predicting how electromagnetic fields might affect an aircrafts computers. Experts know that portable device emit radiation which affects those wavelengths which aircraft use for navigation and communication. But, because they have not been able to reproduce these effects in a laboratory, they have no way of knowing whether the interference might be dangerous or not.

　　The fact that aircraft may be vulnerableto interference raises the risk that terrorists may use radio systems in order to damage navigation equipment. As worrying, though, is the passenger who cant hear the instructions to turn off his radio because the musics too loud.

　　21. The passage is mainly about ___________.

　　A) a new regulation for al airlines

　　B) the defects of electronic devices

　　C) a possible cause of aircraft crashes

　　D) effective safety measures for air flight

　　22. 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 because __________.

　　A) they dont believe there is such a danger as radio interference

　　B) the harmful effect of electromagnetic interference is yet to be proved

　　C) most passengers refuse to take a plane which bans the use of radio and cassette players

　　D) they have other effective safety measures to fall back on

　　24. Why is it difficult to predict the possible effects of electromagnetic fields on an airplanes computers?

　　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 author ___________.

　　A) is in favor of prohibiting passengers use of electronic devices completely

　　B) has overestimated the danger of electromagnetic interference

　　C) hasnt formed his own opinion on this problem

　　D) regards it as unreasonable to exercise a total ban during flight

　　Passage Two

　　Questions 26 to 30 are based on the following passage:

　　The rise of multinational corporations, global marketing, new communications technologies, and shrinking cultural differences have led to an unparalleled increase in global public relations or PR.

　　Surprisingly, since modern PR was largely an American invention, the U.S. leadership in public relations is being threatened by PR efforts in other countries. Ten years ago, for example, the worlds top five public relations agencies were American-owned. In 1991, only one was. The British in particular are becoming more sophisticated and creative. A recent survey found that more than half of all British companies include PR as part of their corporateplanning activities, compared to about one-third of U.S. companies. It may not be long before London replaces New York as the capital of PR.

　　Why is America lagging behind in the global PR race? First, Americans as a whole tend to be fairly provincial and take more of an interest in local affairs. Knowledge of world geography, for example, has never been strong in this country. Secondly, Americans lag behind their European and Asian counterpartsin knowing a second language. Less than 5 percent of Burson-Marshalls U.S. employees know two languages. Ogilvy and Mather has about the same percentage. Conversely, some European firms have half or more of their employees fluent in a second language. Finally, people involved in PR abroad tend to keep a closer eye on international affairs. In the financial PR area, for instance, most Americans read the Wall Street Journal. Overseas, their counterparts read the Journal as well as the Financial Times of London and The Economist, publications not often read in this country.

　　Perhaps the PR industry might take a lesson from Ted Turner of CNN. Turner recently announced that the word foreign would no longer be used on CNN news broadcasts. According to Turner, global communications have made the nations of the world so interdependent 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 of ________.

　　A) an unparalleled increase in the number of public relations companies

　　B) shrinking cultural differences and new communications technologies

　　C) the decreasing number of multinational corporations in the U.S.

　　D) increased efforts of other countries in public relations.

　　27. London could soon replace New York as the center of PR because __________.

　　A) British companies are more ambitious than U.S. companies

　　B) British companies place more importance on PR than U.S. companies

　　C) British companies are heavily involved in planning activities

　　D) four of the worlds top public relations agencies are British-owned

　　28. The word provincial most probably means ________.

　　A) limited in outlook

　　B) like people from the provinces

　　C) rigid in thinking

　　D) interested in world financial affairs

　　29. We learn from the third paragraph that employees in the American PR industry ________.

　　A) speak at least one foreign language fluently

　　B) are ignorant about world geography

　　C) are not as sophisticated as their European counterparts

　　D) enjoy reading a great variety of English business publications

　　30. 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 Three

　　Questions 31 to 35 are based on the following passage:

　　Brazil has become one of the developing worlds great successes at reducing population growth-but more by accident than design. While countries such as India have made joint efforts to reduce birth rates, Brazil has had better result without really trying, says George Martine at Harvard.

　　Brazils population growth rate has dropped from 2.99% a year between 1951 and 1960 to 1.93% a year between 1981 and 1990, and Brazilian women now have only 2.7 children on average. Martine says this figure may have fallen still further since 1990, an achievement that makes it the envy of many other Third World countries.

　　Martine puts it down to, among other things, soap operasand installmentplans introduced in the 1970s. Both played an important, although indirect, role in lowering the birth rate. Brazil is one of the worlds biggest producers of soap operas. Globo, Brazils most popular television network, shows three hours of soaps six nights a week, while three others show at least one hour a night. Most soaps are based on wealthy characters living the high life in big cities.

　　Although they have never really tried to work in a message towards the problems of reproduction, they describe middle and upper class values-not many children, different attitudes towards sex, women working, says Martine. They sent this image to all parts of Brazil and made people conscious of other patterns of behavior and other values, which were put into a very attractive package.

　　Meanwhile, the installment plans tried to encourage the poor to become consumers. This led to an enormous change in consumption patterns and consumption was incompatiblewith unlimited reproduction, says Martine.

　　31. According to the passage, Brazil has cut back its population growth _________.

　　A) by educating its citizens

　　B) by careful family planning

　　C) by developing TV programmes

　　D) by chance

　　32. According to the passage, many Third World countries _________.

　　A) havent attached much importance to birth control

　　B) would soon join Brazil in controlling their birth rate

　　C) havent yet found an effective measure to control their population

　　D) neglected the role of TV plays in family planning

　　33. The phrase puts it down to is closest in meaning to _________.

　　A) attributes it to

　　B) finds it a reason for

　　C) sums it up as

　　D) compares it to

　　34. Soap operas have helped in lowering Brzails birth rate because _________.

　　A) they keep people sitting long hours watching TV

　　B) they have gradually changed peoples way of life

　　C) people are drawn to their attractive package

　　D) they popularize birth control measures

　　35. What is Martines conclusion about Brazi;s population growth?

　　A) The increase in birth rate will promote consumption.

　　B) The desire for consumption helps to reduce birth rate.

　　C) Consumption patterns and reproduction patterns are contradictory

　　D) A countrys production is limited by its population growth.

　　Passage Four

　　Questions 36 to 40 are based on the following passage:

　　There seems never to have been a civilization without toys, but when and how they developed is unknown. They probably came about just to give children something to do.

　　In the ancient world, as is today, most boys played with some kinds of toys and most girls with another. In societies where social roles are rigidly determined, boys pattern their play after the activities of their fathers and girls after the tasks of their mothers. This is true because boys and girls are being prepared, even in play, to step into the roles and responsibilities of the adult world.

　　What is remarkable about the history of toys is not so much how they changed over the centuries but how much they have remained are same. The changes have been mostly in terms of craftsmanship, mechanics, and technology. It is the universality of toys with regard to their development in all parts of the world and their persistence to the present that is amazing. In Egypt, the Americas, China, Japan and among the Arcticpeoples, generally the same kinds of toys appeared. Variations depended on local customs and ways of life because toys imitate their surroundings. Nearly every civilization had dolls, little weapons, toy soldiers, tiny animals and vehicles.

　　Because toys can be generally regarded as a kind of art form, they have not been subject to technological leaps that characterize inventions for adult use. The progress from the wheel to the oxcart to the automobile is a direct line of ascent. The progress from a rattleused by a baby in 3000 BC to one used by an infant today, however, is not characterized by inventiveness. Each rattle is the product of the artistic tastes of the times and subject to the limitations of available materials.

　　36. The reason why the toys most boys play with are different from those that girls play with is that __________.

　　A) their social roles are rigidly determined

　　B) most boys would like to follow their fathers professions

　　C) boys like to play with their fathers while girls with their mothers

　　D) they like challenging activities

　　37. One aspect of the universality of toys lies in the fact that ________.

　　A) technological advances have greatly improved the durability of toys

　　B) the improvement of craftsmanship in making toys depends on the efforts of universities

　　C) the exploration of the universe had led to the creation of new kinds of toys

　　D) the basic characteristics of toys are the same the world over

　　38. Which of the following is the authors view on the historical development of toys?

　　A) The craftsmanship in toy-making has remained essentially unchanged.
