2、 that during the Renaissance one year in ten in Britain, and one in five in Europe, was a famine year. China, with a greater area and more diverse climate, had a famine in some region every year.Famine is a state of affairs in which people are dying in the streets. It therefore attracts the notice o

3、f historians and is recorded. The fact that it strikes people who are aware of having been properly fed and well is more important. Not only are the survivors more resilient, they are also angry at the breakdown of the system and eager to do something about it though it is obvious from the record th

4、at they do not always have the means. Malnutrition is much more insidious. It is a chronic state in which the total food supply or, more often, the supply of certain components such as protein or some of the vitamins, is inadequate. It seems probable that, either constantly or seasonally. It used to

5、 be the usual condition of mankind and was regarded as normal. The rickety appearance of the figures in medieval paintings and drawings is often put down to the incompetence of the artist: it is as likely that most people really did look like that. The exuberance with which poets greeted the "m

6、erry month of May" may, in our dull climate, have had a meteorological basis: it is just as likely that in May, after six months' shortage, there was now an adequate vitamin supply. The promptness with which some sailors succumbed to scurvy after leaving port suggests that they were normall

7、y on the edge of scurvy and needed only a slight worsening of conditions to get it acutely. Others will think of other examples. Hunger and malnutrition are components, of a classic example of a vicious cycle. They lead to enfeeblement or apathy in which nothing either can be done, or seems to be wo

8、rth doing, to alter the state of affairs; this leads to more hunger and malnutrition. There is good reason to think that, in much of the developing world, if the cycle could once the broken, it would never return. (1). According to the text, hunger in the past _.A. occurred more frequently in Britai

9、n than in the rest of EuropeB. was less of a problem than it is todayC. was almost unknown in the Indian subcontinentD. was quite a regular occurrence(2). The writer suggests that famine is different from malnutrition because _.A. it is a far more widespread problemB. it causes rather more people to

10、 dieC. it arouses a desire for action rather than mere apathyD. it tends to affect the rich and well fed more than the poor(3). What does the writer say about malnutrition?_A. It was a common condition in the Middle Ages.B. It arouses a great deal of emotion and interest.C. It affected the competenc

11、e of medieval artists. D. It is a more obvious problem than famine.(4).

13、 in the future2. One of the most fascinating questions about human behavior is each person is different from all others. The answer to this question would explain the aspect of human nature called personality. Some theories assume that inborn characteristics determine human personality. Many observe

14、rs have hypothesized that each person has a dominant temperament, present from birth, that influences his or her behavior during an entire lifetime. According to one of these theories, people can be classified into four basic types: sanguine, choleric, phlegmatic and melancholic. Each type or temper

15、ament is characterized by a unique set of possible strengths and possible weaknesses.Sanguine people are described as the most outgoing of the four temperaments. They are warm, fun-loving, and like the company of others. Because of these strengths, it is said that sanguines often make good salesmen,

16、 actors, or public speakers. Sanguines, however, may have some serious weaknesses. Their problems often come from their lack of discipline. Easily distracted, they often lack the concentration to complete a job or follow through on a promise. For this reason, other people may not trust them. Choleri

17、c people, are quite different from the carefree, emotional sanguines. Because of their strong will, decisiveness, and productivity, cholerics are natural leaders who are good at making vast plans and motivating other people to help them carry out their plans. They are often successful in business, i

18、ndustry, or politics. Choleric weaknesses can be very damaging, however. Because a strong desire to lead, they can be cruel and cold toward those who do not wish to follow. They often do not listen to advice from others, and once they make a decision, they may become hostile toward anyone who questi

19、ons that decision.Phlegmatics are calm, easygoing people who strive for efficiency and organization. Very diplomatic and polite, they make people feel comfortable and generally help keep things running smoothly. For these reasons, they make good teachers, technicians, etc. Phlegmatics, however, ofte

20、n have weaknesses that keep them from becoming successful. Afraid to take chances, they may let opportunities go by. In fact, they may avoid taking any steps to improve their position in life.Melancholics are often considered to be gifted persons who possess creative talent. They are very analytical

21、 and able to understand complicated processes and to note detail. These people can make good doctors, scientists, artists, writers, and musicians. Melancholics are also said to be loyal, idealistic and self-sacrificing. However, melancholics frequently make themselves miserable because they tend to

22、be negative and critical, and put up inflexible standards. They attach importance to everything they do, so they worry too much and see problems everywhere, and complain too much. They often become disappointed because neither they nor the people around them can live up to their high standards.Expla

23、ining human personality in terms of innate temperaments is a theory that has not been generally accepted by psychologists. They criticize it for being too simplistic and unscientific. This may be so; however, present-day psychologists have been unable to formulate a single theory. (1). The word &quo

26、nt from all others?_A. Because of their psychology.B. Because of their different background.C. Because of their various body temperature.D. Because of their innate personalities.3. Chicago taxpayers paid $ 30 an hour to provide reputed mob (黑帮) boss Joseph Lombardo with his own personal chauffeur, T

27、hey also paid city workers who ran business, conducted shake-downs, went to the racetrack and even committed a jewel robbery on city time. All of this occurred in the city's scandal-ridden Department of Streets and Sanitation (卫生). "There's always been a link between the mob and the Dep

28、artment of Streets and Sanitation," said Jerry Gladden, investigator of the Chicago Crime Commission. "The hoods sign in and leave. They get health benefits and a paycheck. It's a common practice."According to the results of an investigation conducted by City Inspector General Ale

29、xander Vroustouris, a sanitation department foreman by the name of Chirs Spina used city crews to clear out city-owned scrap metal (废金属) on department property and sold the scrap to private scrap yards. In addition, the Vroustouris investigation reports, Spina, who was paid $ 20 an hour by Streets a

OSHA were doing their job bookishly.4. Large companies need a way to reach the savings of the public. The

34、same problem, on a smaller scale, faces practically every company trying to develop new products and create new jobs. There can be little prospect of raising the sort of sums needed from friends and people we know, and while banks may agree to provide short-term finance, they are generally unwilling

35、 to provide money on a permanent basis for long-term projects. So companies turn to the public, inviting people to lend them money, or take a share in the business in exchange for a share in future profits. This they do by issuing stocks and shares in the business through the Stock Exchange. By doin

36、g so they can put into circulation the savings of individuals and institutions, both at home and overseas.When the saver needs his money back, he does not have to go to the company with whom he originally placed it. Instead, he sells his shares through a stockbroker to some other saver who is seekin

37、g to invest his money.Many of the services needed both by industry and by each of us are provided by the Government or by local authorities. Without hospitals, roads, electricity, telephones, railway, this country could not function. All these require continuous spending on new equipment and new dev

38、elopment if they are to serve us properly, requiring more money than is raised through taxes alone. The Government, local authorities, and nationalized industries therefore frequently need to borrow money to finance major capital spending, and they, too, come to the Stock Exchange.There is hardly a

39、man or woman in this country whose job or whose standard of living does not depend on the ability of his or her employers to raise money to finance new development. In one way or another this new money must come from the savings of the country. The Stock Exchange exists to provide a channel through

40、which these savings can reach those who need finance.(1).

42、 on The Stock Exchange(3). When the savers want their money back they _.A. ask another company to obtain money for themB. look for other people to borrow money fromC. put their shares in the company back on the market D. transfer their money to a more successful company(4). All the essential service

43、s on which we depend are _.A. run by the Government or our local authorities B. in constant need of financial supportC. financed wholly by rates and taxesD. unable to provide for the needs of the population(5).

44、ed industries _.A. to borrow as much money as they wishB. to make certain everybody saves moneyC. to raise money to finance new development D. to make certain everybody lends money to them5. How much paper do you use every year? Probably you can't answer that question quickly. In 1990 the world&

45、#39;s use of paper was about one kilogram for each person in a year. Now some countries use as much as 50 kilograms of paper for each person in a year. The amount of paper a country uses shows how far advanced the country is, some people say. It is difficult to say whether this is true: different pe

46、ople mean different things by the word 'advanced'. But countries like the United States, England and Sweden certainly use more paper than other countries.Paper, like many other things that we use today, was first made in China. In Egypt and the West, paper was not very commonly used before t

47、he year 1400. The Egyptians wrote on papyrus. Europeans used Parchment for many hundreds of years. Parchment was very strong; it was made from the skin of. Certain young animals. We have learnt some of the most important facts of European history from records that were kept on parchment.The Chinese

48、first made paper about 2000 years ago. China still has pieces of paper which were made as long ago as that. But Chinese paper was not made from the wood of trees. It was made from the hair-like parts of certain plants.Paper was not made in southern Europe until about the year 1100. Scandinavia which

49、 now makes a great deal of the world's paper, did not begin to make it until 1500. It was a German named Schaeffer who found out that one could make the best paper from trees. After that, the forest countries of Canada, Sweden, Norway Finland and the United States became the most important in pa

50、permaking. Today in Finland, which makes the best paper in the world, the paper industry is the biggest in the land. New papermaking machines are very big, and they make paper very fast. The biggest machines can make a piece of paper 300 metres long and six metres wide in one minute.When we think of

51、 paper, we think of newspaper, books, letters, envelopes, and writing paper. But there are many other uses. Only half of the paper that is made is used for books and newspapers, etc.Paper is very good for keeping you warm. Houses are often insulated with paper. You have perhaps seen homeless men asl

52、eep on a large number of newspapers. They are insulating themselves against the cold. In Finland, where in winter it is sometimes - 40centigrade, the farmers wear paper boots in the snow. Nothing could be warmer.Each year, more and more things are made of paper. We have had paper cups, plates, and dishes for a long time. But now we hear that chairs, tables
