Influenza is some

10、times called “flu” or a “bad cold”. He took samples from the throats of patients in his hospital and was able to find the virus of this influenza.There are three main types of the influenza virus. The most important of these are types A and B, each of them having several sub-groups. With the instrum

11、ents at the hospital the doctor recognized that the outbreak was due to a virus group A, but he did not know the sub-group. He reported the outbreak to the World Health Organization in Geneva. W. H.O. published the important news alongside reports of a similar outbreak in Hong Kong, where about 15%2

12、0% of the population had become ill.As soon as the London doctors received the package of throat samples, they began the standard tests. They found that by reproducing itself at very high speed, the virus had multiplied more than a million times within two days. Continuing their careful tests, the d

13、octors checked the effect of drugs used against all the known sub-groups of virus type A. None of them gave any protection. This then, was something new: a new influenza virus against which the people of the world had no ready help whatsoever. Having isolated the virus they were working with, the tw

14、o doctors now dropped it into the noses of some specially selected animals, which contact influenza in the same way as human beings do. In a short time the usual signs of the disease appeared. These experiments revealed that the new virus spread easily, but that it was not a killer. Scientists, like

15、 the general public, called it simply “Asian” flu.The first discovery of the virus, however, was made in China before the disease had appeared in other countries. Various reports showed that the influenza outbreak started in China, probably in February of 1957. By the middle of March it had spread a

16、ll over China. The virus was found by Chinese doctors early in March. But China was not a member of the World Health Organization and therefore did not report outbreaks of disease to it. Not until two months later, when travelers carried the virus into Hong Kong, from where it spread to Singapore, d

17、id the news of the outbreak reach the rest of the world. By this time it was started on its way around the world.Thereafter, WHOs Weekly Reports described the steady spread of this virus outbreak, which within four months swept through every continent.（分数：10.00）(1).The Singapore doctor found the inf

18、luenza was caused byA an influenza virus type B. B a sub-group of virus type A.C a virus only existing in Asia. D a new type of influenza virus.（分数：2.00）A.B.C.D.(2).W. H. O, reported the influenza becauseA a doctor found its virus and reported to it.B many people in Hong Kong suffered from it.C it s

With a mixed clientele ranging from truckers using CBs t

22、o police armed with walkie-talkies to taxi drivers dispatched by radio, it was viewed as an unglamorous business and a technological backwater.But specialized mobile radio, as it is known, has been rediscovered. It is now considered one of the biggest prizes in the all-out war for the public airwave

The reason: high-tech companies have figured out how to profitably rebuild the antiquated dispatching system into an advanced cellular-telephone network that can take on the likes of AT it is not binding on human behavior nor approved or opposed by human conscience.43. _.The evidence as to the va

24、stness of the universe and the complexity of its arrangements continues to grow at an amazing rate. The gap between what we know and all that can be known seems not to diminish, but rather to increase with every new discovery. Fresh unexplored regions are forever opening out. The rapidity of the gro

25、wth of scientific knowledge, in the nineteenth and twentieth centuries, is apt to give students and teachers the impression that no sooner is a problem stated than the answer is forthcoming. A more detailed study of the history of science corrects the impression that fundamental discoveries are made

26、 with dramatic suddenness. Even in our present age no less than fifty years separate the discovery of radioactivity from the explosion of the first atomic bomb. The teacher, giving his brief accounts of scientific discovery, is apt to forget the long periods of misunderstanding, of false hypotheses

27、and general uncertainty, which almost invariably precede the clear statement of scientific truth.44. _.The vast mass of information which scientists have gained has provided the answer to the fundamental questions which, through the centuries, have puzzled and sometimes tortured the human mind. Ther

28、e are many such questions. The study of parasites has provided evidence that organisms which could be self-supporting have become parasites, but hardly any light has been shed on the problem of why they should have done so. What enables an organism to respond to the poisonous secretions of harmful b

29、acteria and organize its resources to defend its life?45. _.To raise the standard of living in any country, two things are required, scientific knowledge, and a population sufficiently educated to understand how to apply it. Without the latter, the expected benefits will not come. Notes: ado 麻烦，忙乱。b

But the tower became

31、 the tower of Babel, according to the Old Testament, when the people were suddenly caused to speak different languages. In modern New York City, a new tower, that of the United Nations Building, thrusts its shining mass skyward. (47) But the realization of the UNs aspirationsand with it the hopes of

32、 the peoples of the worldis threatened by our contemporary Babel: about three thousand different languages are spoken throughout the world today, without counting the various dialects that confound communication between peoples of the same land.In China, for example, hundreds of different dialects a

33、re spoken; people of some villages have trouble passing the time of day with the inhabitants of the next town. In the new African state of Ghana, five million people speak fifty different dialects. In India more than one hundred languages are spoken, of which only fourteen are recognized as official

34、. To add to the confusion, as the old established empires are broken up and new states are formed, new official tongues spring up at an increasing rate. In a world made smaller by jet travel, man is still isolated from many of his neighbors by the Babel barrier of multiplying languages. Communicatio

35、n is blocked daily in scores of ways. Travelers find it difficult to know the peoples of other nations. Scientists are often unable to read and benefit from the work being carried on by men of science in other countries. (48) The aims of international trade, of world accord, of meetings between nati

36、ons, are blocked at every turn; the work of scholars, technologists, and humanists is handicapped. Even in the shining new tower of the United Nations in New York, speeches and discussions have to be translated and printed in the five official UN languageEnglish, French, Spanish, Russian and Chinese

37、. Confusion, delay, suspicion, and hard feelings are the products of the diplomatic Babel.The chances for world unity are lessened if, in the literal sense of the phrase, we do not speak the same language. (49) We stand in dire need of a common tongue, a language that would cross national barriers,

38、one simple enough to be universally learned by travelers, businessmen, government representatives, scholars, and even by children at school.Of course, this isnt a new idea. Just as everyone is against sin, so everyone is for a common language that would further communication between nations. (50) Wh

39、at with one thing and anotherour natural state of drift as human beings, our rivalries, resentments, and jealousies as nationswe have up until now failed to take any action. I propose that we stop just talking about it, as Mark Twain said of the weather, and do something about it. We must make the c
