(10 points) 1 Formal economic forecasting is usually based on a (1)_ theory as to how the economy works. Some theories are complicated, and their

2、 application requires an elaborate (2)_ of cause and effect. Others are relatively simple, (3)_ most developments in the economy to one or two basic factors. Many economists, for example, believe that changes in the supply of money (4)_ the rate of growth of general business activity. Others (5)_ a

3、central role to investment in new facilities housing, industrial plants, highways, and so forth. In the United States, where consumers (6)_ such a large share of economic activity, some economy believe that consumer decisions to (7)_ or save provide the principal (8)_ to the future course of the ent

4、ire economy. Obviously the theory that a forecaster applies is of (9)_ importance to the forecasting process; it (10)_ his line of investigation, the statistics he will regard as most important, and many of the techniques he will apply. Although economic theory may determine the general (11)_ of a f

5、orecast, judgment also often plays an important role. A forecaster may decide that the circumstances of the moment are (12)_ and that a forecast produced by the (13)_ statistical methods should be modified to take account of special current circumstances. This is particularly necessary when some eve

6、nt outside the Usual run of economic activity has an a (14)_ economic effect. For example, forecasts of 1987 economic activity in the United States were more accurate when the analyst correctly foresaw that the exchange value of the dollar would (15)_ sharply during the year that consumer spending w

7、ould slacken, and that (16)_ rates would rise only moderately. None of these conclusions followed (17)_ purely economic analysis; they all required judgment as to future decisions (18)_, an economist may decide to adjust an economic forecast that was made by traditional methods to take account of ot

(40 points) 21 Could HIV, the virus that causes AIDS, be weakening? The results of a study conducted in Belgium, at the Inst

13、itute of Tropical Medicine in Antwerp, seem to suggest that in one corner of the world it might be. The report, published in the latest issue of AIDS, a specialist journal, concludes that HIVs ability to replicate (known technically as its virulence) may have decreased since the start of the pandemi

14、c. Kevin Aden, the lead author of the paper, stresses that the study is based on a small set of samples and does not prove that HIVs virulence is attenuating around the world. However, it does offer new insights into the evolution of the disease. Dr. Arien looked at 24 blood samples collected from u

15、ntreated patients attending an HIV/ AIDS clinic in Antwerp. A dozen of these samples were taken between 1986 and 1989; the other 12 were collected between 2002 and 2003. First, he analyzed the samples to find their viral load (the number of virus particles per cubic centimeter) and the subtype of vi

16、rus involved. In Europe and North America, the predominant subtype is B; in sub-Saharan Africa, where the epidemic is at its worst, the predominant subtype is C. Most of Dr. Ariens samples were of subtype B. Having done this analysis, he paired the samples off for a series of replicative “duels“. Ea

17、ch sample from the earlier series was matched with the most similar one from the later series, and they were placed in identical cell cultures to see which would multiply the most. The result was that 75% of the viruses from 2002-03 were less virulent than apparently similar counterparts from 1986-8

18、9 a statistically significant observation. Dr. Ariens caution is sensible, at least until someone replicates the work elsewhere. But his conclusion is not necessarily surprising. Such viral attenuation, as it is known, is one way that vaccines are produced. What causes attenuation in wild viruses, t

19、hough, is a matter of speculation. Dr Arien believes that in this case the attenuation could be the result of what he calls “serial genetic bottlenecks“ during transmission from host to host. These act to reduce the genetic diversity (and thus the replicative fitness) of the virus. Genetic diversity

20、 is known to be an important component of HIVs virulence. But what might cause the bottlenecks is still unclear. A second reason for caution besides the small size of the study is, as Geoffrey Garnett, a professor of microparasite epidemiology at Imperial College, London, points out, that the abilit

21、y of a virus to infect cells in a test-tube is not the same as its ability to cause disease and death in a human host. Nevertheless, Dr Adens result is intriguing, and surely worth following up in a larger piece of research. 21 The word “attenuating“(Paragraph 1) most probably means （ A） weakening.

22、（ B） accentuating. （ C） accelerating. （ D） increasing. 22 We can learn from para. 2 that （ A） a dozen of blood examples were from the patients died between 1986 and 1989. （ B） Dr. Arien studied the blood examples to find the cause of AIDS. （ C） the subtype of virus involved is different due to diffe

23、rent places. （ D） 3/4 of the viruses appeared to be more harmful than before. 23 Which of the following is true according to the text? （ A） In his paper, Dr. Arien proves that HIV is weakening in Europe and Africa. （ B） Two kinds of blood samples are placed in two different cell cultures to be obser

24、ved. （ C） Dr. Arien has made the cause of attenuation of virus clear. （ D） There are 3/4 of the viruses in Dr. Ariens study proving to be less harmful. 24 By saying “Dr. Ariens caution is sensible“(Line 1, Paragraph 3), the author implies that （ A） The result of Ariens research is worth further stud

25、ies. （ B） the result of Dr. Ariens research is not true. （ C） Dr. Ariens conclusion has been made by others before. （ D） Dr. Ariens result is based on the small size of study. 25 Which is the best title for the text? （ A） New Method of AIDS Treatment. （ B） A Small Hope in HIV Research. （ C） AIDS Dam

26、age May Decrease Soon. （ D） The Special Bottlenecks to HIV Study. 26 Despite the doubts, and despite complaints from shop owners, Londons congestion charge introduced in February 2003 has managed to ease the gridlock in the city centre. Traffic is down by 18%, jams by 30%. The schemes biggest weakne

27、ss is that it is crude: drivers pay 8 ($14) to enter the zone between 7am and 6:30pm, regardless of how congested the roads are, or how long they stay. So road-pricing fans are watching trials by Transport for London (TfL) of a new detection system, called tag-and-beacon, with interest. Under such a

28、 scheme (used in Singapore and on some European roads) cars are fitted with electronic tags that are read by roadside masts. If the trial is successful, TfL says that the city could switch to the system once the contract to run the congestion charge is re-let in 2009. Currently, cameras are used to

29、read license plates and track motorists. They are not always reliable: an individual camera identifies only around 70% of cars. Most driven get photographed more than once, which boosts the systems effectiveness to over 95%, but that still leaves several thousand vehicles per day whose details must

30、be laboriously checked by hand. Tag-and-beacon technology is much more accurate, with an identification rate of over 99%. TfL says the trial is partly designed to see whether the new system could allow drivers to pay charges by direct debit. That would be popular with motorists, who complain that th

31、e current payment system is unfriendly: the toll for a days travel must be paid manually online, by phone or in a shop by midnight, with steep fines levied on forgetful drivers. More precise detection also allows for more precision in policy, and road-pricing enthusiasts see radical possibilities ah

32、ead. TfL says it is considering using the new technology to charge drivers each time they cross the zone boundary (up to a daily maximum), instead of paying once for an entire days travel. That would be cheaper for drivers who make few trips into the zone, although drivers who spend a long time trun

33、dling around without leaving (thereby causing the most congestion) would get off lightly, too. Further refinements may be possible. The current system has cut traffic most drastically in the middle of the day, when congestion is at its lowest. Demand for road space would better match supply if charg

34、es were variable high at the busiest times of day and low in quiet periods. Such a time-sensitive, variable-charging scheme using a tag-and-beacon system was endorsed last year by Bob Kiley, the TfLs boss, who also said that he wanted to extend the congestion charge to other parts of London. That wo

35、uld be controversial, and Mr. Kileys underlings were quick to insist that his musings were not official policy. But the original scheme was controversial too, yet Ken Livingstone, Londons mayor and its biggest backer, was re-elected after introducing it. It would be a shame if timidity took hold now

36、. 26 From paragraph 1, we know that Londons congestion charge scheme （ A） has got much support from shop owners. （ B） has reduced 18% of traffic jams. （ C） asks $14 for entering the city center after 7pm. （ D） demands same charges from drivers in spite of road conditions. 27 The tag-and-beacon syste

37、m （ A） is being tested by road-pricing fans. （ B） has been used on European roads. （ C） need cars to be equipped with electronic tags. （ D） will be carried out in 2009. 28 The new detection technology has an identification rate of （ A） 30%. （ B） over 99%. （ C） 70%. （ D） over 95%. 29 Which of the fol

38、lowing statements is true about TfL? （ A） It will re-let the contract to run the congestion charge. （ B） It conducts the trim of the new detection system. （ C） It is thinking of charging drivers once for an entire days travel. （ D） Its boss ever wanted to extend the congestion charge to other cities

39、. 30 From the last paragraph, we can infer that （ A） Bob Kiley as TfLs boss approved the new scheme. （ B） Mr. Kileys underlings confirmed his suggestion. （ C） Londons mayor disagrees Mr. Kileys idea. （ D） Ken Livingstone would feel shameful if he changed the scheme. 31 A growing number of women are

40、rising to the top and beginning to change the culture of the workplace. This should be a season of celebration. After all, by many measures, theres never been a better time to be a woman. In places like Scandinavia and Britain, a third or more of all corporate managers are now women. The number of f

41、emale executive directors of FISE 100 companies nearly doubled from 2000 to 2004. Latin America has seen a 50 percent jump in the number of women politicians in the last decade. Japan voted 26 new female parliamentarians into office this year. Of course, the jewel in the equal-opportunity crown was

42、this falls election of Angela Merkel once nicknamed “the Girl“ by Helmut Kohlto Germanys highest office. But as always, statistics tell a multifaceted story. Sure, its no longer an anomaly to have a female CEO but there are still only 17 female executive directors in the largest FTSE 100 companies.

43、In the EU Parliament, only 23 out of 162 members are female. In Britain, studies show that women have never been more dissatisfied with the workplace. No wonder: the EU pay gap between men and women shrank only one point in the last couple of years, to 17.5 percent. So where does all this leave us?

44、With some big challenges that require more female leadership to solve. At some major companies including Shell and British Telecomwomen are combating the old-boys club atmosphere by starting their own networks, linking top female leaders with up-and-comers they can mentor. Labor flexibility is also

45、on the agenda; in parts of Europe, top female legislators have fought to give employees with children or elderly parents the right to ask for adjustable hours. Perhaps most important, there is an increasingly vibrant debate around work-life balance. Study after study shows that it is a working woman

46、s second full-time job as caregiver that makes it most difficult for her to stay on the career ladder. While extra benefits and longer maternity, leave can help, they arent a complete solution. Clearly, some out-of-the-box thinking is required. And thats where women come in. In countries like Camero

47、on, Bolivia and Malaysia, greater numbers of women in public office have resulted in less spending on the military and more on health, education and infrastructure. Norways woman-heavy Parliament recently passed a law mandating that 40 percent of directors on corporate boards be women. And in German

48、y, the archetypal outsider a woman who grew up on the wrong side of the Iron Curtain will likely take the helm in a country with virtually no other women in top positions of power. No longer “the Girl“ but poised to become the chancellor, Merkel is a symbol of how far women have come and the work th

49、at remains to be done. 31 According to paragraph two, what is the most important issue of womens achievement in politics? （ A） In Scandinavia and Britain, women account for more than 30% of corporate managers. （ B） Between 2000 and 2004, women executive directors in FTSE firms almost doubled. （ C） The election of Angela Merkel as one of the highest officials in Germany: （ D） Japan has a new group of 26 women in the parliament. 32 We can learn from th
