12、The age distribution of the total population has a very (21) effect on the available workforce. If the population has a high (22) of very young people or of (23) too old to work, then the available workforce would be lower than (24) there were an (25) spread age distribution. If the population grows

13、 raidly (26) natural increase, i.e., the number of births greatly (27) the number of deaths, then as a total population increases the proportion of the workforce (28) .Sometimes a population is described as aging, (29) means that the birth rate is either falling or growing very slowly, and as people

14、 retire (30) the workforce there are insufficient numbers of young people entering it to (31) those who are leaving it. The population is top heavy with older people. So the (32) of the population in the workforce declines when there is (33) a rapid increase in births or a falling birth rate.The age

15、 distribution of the population has several important effects on the economy. If the population is aging and there is an increase in the number of people retiring (34) a corresponding increase in the number entering the workforce, this raises the problem of the ability of the economy to provide a (3

16、5) level of social services to the retired group. If the (36) are to be cared (37) in special homes or hotels, finance must be (38) for that purpose. If the size of the workforce is small relative (39) the total population, then the government tax receipts are relatively low and either the governmen

17、t has less money available to it or the workforce members have to be (40) more heavily.（分数：20.00）A.littleB.markedC.muchD.lotA.portionB.correlationC.proportionD.approximationA.thoseB.onesC.whoD.thatA.whenB.ifC.unlessD.otherwiseA.evenlyB.oddlyC.smoothlyD.decentlyA.withB.toC.upD.fromA.sustainsB.exceeds

20、in the roof of a greenhouse which allows the suns rays to enter but prevents the heat from escaping.According to a weather experts prediction, the atmosphere will be 3 warmer in the year 2050 than it is today, if man continues to burn fuels at the present rate. If this warming up took place, the ice

21、 caps in the poles would begin to melt, thus raising sea level several meters and severely flooding coastal cities. Also the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere, possibly resulting in an alteration of the earths chief food-growing

22、 zones.In the past, concern about a man-made warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet. But the weather experts are now paying more attention to West Antarctic, which may be affected by only a few degrees of warming: in

23、other words, by a warming on the scale that will possibly take place in the next fifty years from the burning of fuels.Satellite pictures show that large areas of Antarcitic ice are already disappearing. The evidence available suggests that a warming takes place. This fits the theory that carbon dio

24、xide warms the earth.However, most of the fuel is burnt in the northern hemisphere, where temperatures seem to falling. Scientists conclude, therefore, that up to now natural influences on the weather have exceeded those caused by man. The question is: Which natural cause has the most effect on the

25、weather?On possibility is the variable behavior of the sun. Astronomers at one research station have studied the hot spots and “cold“ spots (that is, the relatively less hot spots) on the sun. As the sun rotated, every 27.5 days, it presents hotter of “colder“ face to the earth, and different aspect

26、s to different parts of the earth. This seems to have a considerable effect on the distribution of the earths atmospheric pressure, and consequently on wind circulation. The sun is also variable over a long term: its heat output goes up and down in cycles, the latest trend being downward.Scientists

27、are now finding mutual relations between models of solar-weather interactions and the actual climate over many thousands of years, including the last Ice Age. The problem is that the models are predicting that the world should be entering new Ice Age and it is not. One way of solving this theoretica

28、l difficulty is to assume a way of thousands of years while the solar effects overcome the inertia (惯性的) of the earths climate. If this is right, the warming effect of carbon dioxide might thus be serving a useful counter-balance to the suns diminishing heat.（分数：5.00）(1).It can be concluded that a c

29、oncentration of carbon dioxide in the atmosphere would _.（分数：1.00）A.prevent the suns rays from reaching the earths surfaceB.mean a warming up in the ArcticC.account for great changes in the climate in the northern hemisphereD.raise the temperature of the earths surface(2).The article was written to

30、explain _.（分数：1.00）A.the greenhouse effectB.the solar effects on the earthC.the models of solar-weather interactionsD.the causes affecting weather(3).Although the fuel consumption is greater in the northern hemisphere, temperatures there seem to be falling. This is _.（分数：1.00）A.mainly because the le

31、vels of carbon dioxide are risingB.possibly because the ice caps in the poles are meltingC.exclusively due to the effect of the internal of the earths climateD.partly due to variations in the output of solar energy(4).On the basis of their models, scientists are of the opinion that _.（分数：1.00）A.the

32、climate of the world should be becoming coolerB.it will take thousands of years for the inertia of the earths climate to take effectC.the man-made warming effect helps to increase the solar effectsD.the new Ice Age will be delayed by the greenhouse effect(5).If the assumption about the delay of a ne

33、w Ice Age is correct, _.（分数：1.00）A.the best way to overcome the cooling effect would be to burn more fuelsB.ice would soon cover the northern hemisphereC.the increased levels of carbon dioxide in the atmosphere could warm up the earth even more quicklyD.the greenhouse effect could work to the advant

34、age of the earth九、Text 2(总题数：1，分数：5.00)Psychologists say the one factor that differentiates people who are creative from those who arent is belief-creative people believe they are creative. To be creative, you simply have to believe and act as if you are. Once you believe you are creative, you begin

35、 to find ideas and to imagine all kinds of probable and improbable solutions.Here are a few techniques to help you get started looking for ideas you may already have in your mind.Play a different role. Suppose you want to improve your companys training program. Play the role of another person. Write

36、, from the perspective of that role, what changes the person would make. Record any interesting thoughts or new ideas.Randomly pick something and compare it with your problem. Open a dictionary and randomly, without looking, pick a word. Force yourself to make a comparison between the problem and th

37、e word.Suppose you are having a problem with a manager and you randomly pick the word “pencil“. You might list the characteristics of the pencil and determine how those characteristics are like your problem.Imagine you have a magic wand (魔杖). Consider what changes or actions you will use the wand to

38、 create, especially those that wouldnt normally be possible. After letting your imagination run, ask yourself what specific features of those wishes particularly appeal to you. Think of some feasible changes of actions that embody some of those specific features.Think outrageously. The more incredib

39、le and divergent from conventional thinking an idea is, the greater the possibilities for new twists. A frozen-fish processor used this technique. A line of his frozen fish tasted bland and boring. He tried everything to improve the taste, including keeping the fish alive in holding tanks until he p

40、ut a predator (食肉动物) in the holding tank with fish. The fish kept moving to escape the predator and they retained their vitality and flavor.Challenge assumptions. Reserve the assumptions you make about problems. List the assumptions and write the opposite. Henry Ford challenged the practice of havin

41、g workers to go where building materials were kept. In order to build cars, by creating a system that brought the materials to the workers instead. With this reversal, the assembly line was born.Be an artist. Write a poem about your job. Poetry helps give a voice to your wildest imagination, which m

42、ay lead to new ideas.Try the above methods and test if your creativity might be somewhat improved.（分数：5.00）(1).What does one have to be if he wants to make himself creative according to the author?（分数：1.00）A.He should try to be as creative as possible.B.He may set up a problem and then try to concei

43、ve all the possible solutions to it.C.He should study all the techniques mentioned in the passage and try to use them.D.He should play a different role from the one he plays now.(2).What kind of techniques has the author used by taking the example of “a pencil“?（分数：1.00）A.Metaphor.B.Simile.C.Analogy

44、.D.Association.(3).What instruction does the author have in his mind by asking you to imagine you have a magic wand?（分数：1.00）A.To increase your imagination power.B.To conceive a magic trick.C.To set up particularly attractive wishes.D.To enable you to perform miracles.(4).The sentence “the more incr

45、edible and divergent from conventional thinking an idea is, the greater the possibilities for new twists“ can best be paraphrased as _.（分数：1.00）A.“The more far-fetched a thought is, the less possible it is to be wise“B.“A good idea can often come to ones mind unexpectedly“C.“The more conflicting an

46、idea is from the traditional way, the more likely it is to be put into practice“D.“The farther an idea is from the generally accepted norms, the more useful it is to create new possibilities“(5).All the following things you are advised to do, according to the author, make one creative EXCEPT _.（分数：1

47、.00）A.to learn from such creative persons as Henry FordB.to develop ones thinking power in every conceivable wayC.to sum up all the successful methods ever tried by creative peopleD.to learn to be more creative by doing easy things in an unusual way十、Text 3(总题数：1，分数：5.00)The American educational sys

48、tem is based on the idea that as many people as possible should have access to as much education as possible. This fact alone distinguishes the U.S. system from most others, since in most others the objective is as much to screen people out as it is to keep them in. The U.S. system has no standardiz

49、ed examinations whose results systematically prevent students from going on to higher levels of study, as the British and many other systems do. Through secondary school and sometimes in post-secondary institutions as well, the American system tries to accommodate students even if their academic aspirations and aptitudes are not high, even if they are physically (an
