We are not surprised when we watch on TV that a politician has talked with French President in Paris and attended a meeting in Beijing on the same day. 2 , if a person takes long-distance
2、flying frequently, he can be so tired that he maybe feel his brain is in one country, his 3 in another. 4 , he 5 knows where he is. When we fly from east to west or 6 versa, the 7 we experience after taking a longdistance flying is 8 , because we cross time zones. According to doctors, air travelers
3、, after crossing several time zones, are in no 9 to go to work, and they should go 10 to bed 11 arrival. As to airline pilots who often live 12 their own watches and ignore local time, there is no need for them to worry about their health although they sometimes have breakfast at midnight, because t
4、hey are used to 13 and are 14 fit. Many businessmen like long-distance flights, thinking they are 15 to have been chosen and they are out for promotion. They are lucky if the company follows the doctor“s advice and allow them to rest for a day or two 16 working. However, sometimes the manager is so
5、energetic that he believes everyone is 17 to be as fit as he is. Since he has never felt 18 after flying himself, the work he assigns is so 19 that the employee is too 20 to carry the work out satisfactorily. That is disastrous for the employee“s health and the company“s reputation.（分数：400.00）A.ordi

9、en creamjust to be safe“. More and more people are questioning about sunscream. Can sunscreen cream help protect me against melanomas? How safe are we in applying these chemical cocktails? Does it actually stop melanomas, the most dangerous type of skin cancer, from forming? As is known to all, suns
10、creen cream can protect the skin from the harmful effects of sun. The most important function of it is the prevention of skin cancer. A great number of American people like to use it. Surprisingly, this kind of cancer is increasing in incidence faster than any other cancer in the United States. It s
11、eems that sunscreen actually increases the risk of skin cancer. More and more health experts are taking a discommendable attitude to the application of sunscreen. Researchers show that the earlier finding has many flaws and is unable to prove the exact function because they fail to take into account
12、 many exceptional cases. For instance, some people prefer to use sunscreen cream while going out. However, sunscreen cream users suffer from cancer more often. In fact, sunscreen cream allows people to remain exposed in the sun longer. People are likely to get skin problem under the sunshine for a l
13、ong time. Besides, many people use the sunscreen cream in an inappropriate way. The sunscreen cream should be applied about half an hour before going outside, so the time is enough for the sunscreen to soak in and take effect. In fact, the protection of sunscreen will not last indefinitely. It shoul
14、d be reapplied at least every two hours when people stay outdoors for a prolonged period. After swimming, bathing, perspiring heavily, or drying off with a towel or handkerchief, you had better reapply it, too. Millions of gallons of sunscreen cream are consumed each year. Only 5% of products overal
15、l met the criteria for safety and sunscreen effectiveness. Three of five brand name products can not protect the skin from sun damage sufficiently or they contain hazardous chemicals, according to a report by Environmental Working Group (EWG). It is time to change our misunderstanding now. In fact,
16、besides the sunshine-preventing function, it also has the function of protecting our skin. We all know that the sun impacts collagen production in the skin, and without collagen, skin won“t naturally maintain that plump, moist, youthful, wrinkle-free look. Without the protection of sunscreen cream,
17、just a few minutes of daily sun exposure over the years can cause noticeable changes in skin. Sunscreen cream can protect our skin from these damaging rays, so that even if we do spend time outdoors, our face is less likely to give away our age.（分数：5.00）(1).What can we learn from the first paragraph

Nothing could be further from the truth. The relation between interest rates and i
23、nflation is uncertain. And there are long, variable lags before policy changes have any effect on the economy. Hence the analogy that likes the conduct of monetary policy to driving a car with a blackened windscreen, a cracked rearview mirror and a faulty steering wheel. Given all these disadvantage
24、s, central bankers seem to have had much to boast about. Average inflation in the big seven industrial economies fell to a mere 2.3% last year, close to its lowest level in 30 years, before rising slightly to 2.5% this July. This is a long way below the double-dig- it rates which many countries expe
25、rienced in the 1970s and early 1980s. It is also less than most forecasters has predicted. In late 1994 the panel of economists which The Economist polls each month said that America“s inflation rate would average 3.5% in 1995. In fact, it fell to 2.6% in August, and is expected to average only abou
26、t 3% for the year as a whole. In Britain and Japan inflation is running half a percentage point below the rate predicted at the end of last year. This is no flash in the pan; over the past few years, inflation has been continually lower than expected in Britain and America. Economists have been part
27、icularly surprised by favourable inflation figures in Britain and the United States, since conventional measures suggest that both economies, and especially that of America, have little productive slack. America“s capacity utilisation, for example, hit historically high levels earlier this year, and
28、 its jobless rate (5.6% in August) has fallen below most estimates of the natural rate of unemploymentthe rate below which inflation has taken off in the past. Why has inflation proved so mild? The most thrilling explanation is, unfortunately, a little defective. Some economists argue that powerful
29、structural changes in the world have up-ended the old economic models which were based upon the historical link between growth and inflation.（分数：5.00）(1).According to the text, making monetary policy changes _.（分数：1.00）A.is comparable to driving a carB.is similar to carrying out scientific workC.wil

34、 sold your souls, but must you corrupt our nation and threaten our children as well?“ At Time Warner, however, such questions are simply the latest manifestation of the soul-searching that has involved the company ever since the company was born in 1990. It“s a self-examination that has, at differen
35、t times, involved issues of responsibility, creative freedom and the corporate bottom line. At the core of this debate is chairman Gerald Levin, 56, who took over from the late Steve Ross in the early 1990s. On the financial front, Levin is under pressure to raise the stock price and reduce the comp
36、any“s mountainous debt, which will increase to $17.3 billion after two new cable deals close. He has promised to sell off some of the property and restructure the company, but investors are waiting impatiently. The flap over rap is not making life any easier for him. Levin has consistently defended
37、the company“s rap music on the grounds of expression. In 1992, when Time Warner was under fire for releasing Ice-T“s violent rap song Cop Killer, Levin described rap as a lawful expression of street culture, which deserves an outlet. “The test of any democratic society,“ he wrote in a Wall Street Jo
38、urnal column, “lies not in how well it can control expression but in whether it gives freedom of thought and expression the widest possible latitude, however disputable or irritating the results may sometimes be. We won“t retreat when we face any threats.“ Levin would not comment on the debate last
39、week, but there were signs that the chairman was backing off his hard-line stand, at least to some extent. During the discussion of rock singing verses at last month“s stockholders“ meeting, Levin asserted that “music is not the cause of society“s ills“ and even cited his son, a teacher in the Bronx
40、, New York, who uses rap to communicate with students. But he talked as well about the “balanced struggle“ between creative freedom and social responsibility, and he proclaimed that the company would launch a drive to develop standards for distribution and labeling of potentially objectionable music
41、. The 15-member Time Warner board is generally supportive of Levin and his corporate strategy. But insiders say some of them have shown their concerns in this matter. “Some of us have known for many, many years that the freedoms under the First Amendment are not totally unlimited,“ says Luce. “I thi
42、nk it is perhaps the case that some people associated with the company have only recently come to realize this.“（分数：5.00）(1).An American senator criticized Time Warner for _.（分数：1.00）A.its raising of the corporate stock priceB.its self-examination of the soulC.its neglect of social responsibilityD.i
43、ts emphasis on creative freedom(2).The word “flap“ (Para. 3) here means “_“.（分数：1.00）A.controversyB.fearC.disasterD.solution(3).In 1992, Time Warner caused public outrage because it _.（分数：1.00）A.sacked workers as a result of restructuringB.issued a record promoting violenceC.advocated the culture of
44、 the streetD.challenged the freedom of expression in democratic society(4).In the face of recent attacks on the company, Levin _.（分数：1.00）A.stuck to a strong stand to defend freedom of expressionB.softened his tone and introduced a new initiativeC.yielded to objections and resigned from the companyD
45、.requested unconditional support from the 15-member board(5).We can infer from the last paragraph that _.（分数：1.00）A.profits and social responsibility can rarely go hand in hand in the companyB.few people are concerned about corporate responsibilityC.the debate over Time Warner“s policy will soon inv
