If you do, youll find it harder to wake and may experience the unstable feeling for a while.For those who are worried about the after-affect of a nap, there i

27、s the caffeine nap. A caffeine nap is taken after an intake of caffeine, so that you are asleep while your body digests the caffeine. After a 15 -30 minutes nap, you wake up and have the caffeine in your system. This is great if you need to be instantly on the move after a nap, and you can bounce ou

28、t of your sleeping state and jump into refreshed Work feeling.Finding 15 -30 minutes to take a nap in a day sometimes seems difficult, but doing so is very helpful to your productivity.

Nothing could be further from t

34、he truth. The relation between interest rates and inflation is uncertain. And there are long, variable lags before policy changes have any effect on the economy. Hence the analogy that likens the conduct of monetary policy to driving a car with a blackened windscreen, a cracked rearview mirror and a

35、 faulty steering wheel.Given all these disadvantages, 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

36、 the double-digit rates which many countries experienced 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 Americas inflation rate would average 3.5% in 1995. In fact, it fell to 2.6%

37、in August, and is expected to average only about 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

38、 Britain and America.Economists have been particularly 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. Americas capacity utilisation, for example, hit hi

39、storically high levels earlier this year, and its jobless rate (5.6% in August) has fallen below most estimates of the natural rate of unemployment - the rate below which inflation has taken off in the past.Why has inflation proved so mild? The most thrilling explanation is, unfortunately, a little

40、defective. Some economists argue that powerful 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 changesA is comparable to driving a car.B is similar

41、to carrying out scientific work.C will not influence the economy immediately.D will have an immediate impact on the inflation rate.（分数：1.00）A.B.C.D.(2).From the text we learn thatA there is a clear relationship between inflation and interest rates.B the economy always follows particular trends.C the

42、 current economic problems are entirely predictable.D the present economic situation is better than expected.（分数：1.00）A.B.C.D.(3).The text suggests thatA the previous economic models are still applicable.B an extremely low jobless rate will lead to inflation.C a high unemployment rate will result fr

43、om inflation.D interest rates have an immediate effect on the economy.（分数：1.00）A.B.C.D.(4).By saying “This is no flash in the pan“ (Para. 3), the author means thatA the low inflation rate will continue.B the inflation rate will rise again.C inflation will disappear entirely.D there is no inflation a

44、t present.（分数：1.00）A.B.C.D.(5).How does the author feel about the present situation?A Tolerant. B Indifferent.C Disappointed. D Surprised.（分数：1.00）A.B.C.D.十、Passage 3(总题数：1，分数：5.00)Thousands of years ago man used handy rocks for his surgical operations. Later he used sharp bone or horn, metal knives

45、 and more recently, rubber and plastic. And that was where we stuck, in surgical instrument terms, for many years. In the 1960s a new tool was developed, one which was, first of all, to be of great practical to the armed forces and industry, but which was also, in time, to revolutionize the art and

46、science of surgery.The tool is the laser and it is being used by more and more surgeons all over the world, for a very large number of different complaints. The word laser means: light amplification by stimulated emission of radiation. As we all know, light is hot; any source of light-from the sun i

47、tself down to a humble match burning -will give warmth. But light is usually spread out over a wide area. The light in a laser beam, however, is concentrated. This means that a light with no more power than that produced by an ordinary electric light bulb becomes intensely strong as it is concentrat

48、ed to a pinpoint-sized beam.Experiments with these pinpoint beams showed researchers that different energy sources produce beams that have a particular effct on certain living cells. It is now possible for eye surgeons to operate on the back of the human eye without harming the front of the eye, simply by passing a laser beam right through the eyeball. No knives, no stit
