The 1 took a sharp upward leap with the invention of writing, but even 2 it remained painfully slow for several centuries. In Europe the next great leap forward 3 knowledge acquisition did not occur 4 the invent
15、ion of movable type in the 15th century by Gutenberg and others. 5 to 1,500, by the most optimistic 6 , Europe was producing books at a rate of 1,000 titles per year. This means that it 7 a full century to produce a library of 100,000 tides. By 1950, four and a half 8 later, the rate had accelerated
16、 so sharply that Europe was producing 120,000 titles a year. 9 once took a century now took only ten months. By 1960, a 10 decade later, the rate had made another significant jump, 11 a century“s work could be finished in seven and a half months. 12 , by the mid-sixties, the output of books on a wor
17、ld 13 , Europe included, approached the prodigious figure of 900 tides per day. One can 14 argue that every book is a net gain for the advancement of knowledge. Nevertheless we find that the accelerative 15 in book publication does, in fact, crudely 16 the rate at which man discovered new knowledge.
18、 For example, prior to Gutenberg 17 11 chemical elements were known. Antimony, the 12th, was discovered 18 about the time he was working on his invention. It was fully 200 years since the 11th, arsenic, had been discovered. 19 the same rate of discovery continued, we would by now have added only two
19、 or three additional elements to the periodic table since Gutenberg. 20 , in the 450 years after his time, certain people discovered some seventy additional elements. And since 1900 we have been isolating the remaining elements not at a rate of one every two centuries, but of one every three years.（

Merely graduating from such a high schoo
23、l is difficult, much less becoming a high-caliber science or engineering student. Schools with students from a higher socioeconomic level would not tolerate the obstacles I encountered daily. Improvements need to be made efficiently and made soon, or the divisions among people in this country will o
24、nly become more extreme. Of course, there are things that concerned citizens can do to help. Get involved with a school, especially one in a poor area. Volunteer to give a presentation or just to spend time with the children. My students were excited to talk to an insurance salesperson who came to g
25、ive a career exploration lecture. They not only were genuinely interested in the opportunities he described but also were amazed that such a man would donate an afternoon to them. Although those measures can help, they are not enough. For teaching to be effective, the entire environment of the inner
26、 city needs to be changed. Teaching someone the difference between velocity and acceleration is irrelevant if the person is hungry and scared. Programs that educate parents in child-rearing, organize low-income groups into cooperative units, fight drug trafficking and help to clean up the ghettos ph
27、ysically will improve the life in the community. The small alterations and “new“ proposals currently filling the newspapers are certainly not strong enough to transform a decaying and demoralized school structure that has been disintegrating for decades. Inner-city schools need so much more, and the
28、 children deserve so much more than our society is willing to give. Like many other people, I entered the teaching profession eager to investigate change and found many institutionalized obstacles in my way. It should not be so difficult to make a difference.（分数：5.00）(1).By saying “an uphill battle“
29、, the author means _.（分数：1.00）A.a tough taskB.an easy jobC.an upgrade classD.climbing a hill(2).We can learn from the text that _.（分数：1.00）A.the political circle will offer the help to the high schoolsB.giving a presentation is beneficial to studentsC.teaching methods have to be changedD.students ar

32、author“s remarks that _.（分数：1.00）A.we should educate more high schools studentsB.the obstacles in teachers“ way should be moved awayC.the decaying school buildings should be reconstructedD.we should build up more high schools in our city九、Text 2(总题数：1，分数：5.00)Many phrases used to describe monetary p
33、olicy, such as “steering the economy to a soft landing“ or “a touch on the brakes“, makes it sound like a precise science. Nothing could be further from the truth. The relation between interest rates and inflation is uncertain. And there are long, variable lags before policy changes have any effect
34、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 disadvantages, central bankers seem to have had much to boast about. Average inflation in the big seven ind
35、ustrial 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-digit rates which many countries experienced in the 1970s and early 1980s. It is also less than most forecasters has predicted. In lat
36、e 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 about 3% for the year as a whole. In Britain and Japan inflation is running half a percentage point b
37、elow 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 particularly surprised by favourable inflation figures in Britain and the United States, since conven
38、tional 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 its jobless rate (5.6% in August) has fallen below most estimates of the natural rate of unemplo
39、ymentthe 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 structural changes in the world have up-ended the old economic models which were based upon the h
40、istorical 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.will not influence the economy immediatelyD.will have an immediate impact on the inflation rate(2).F
41、rom the text we can learn that _.（分数：1.00）A.there is a clear relationship between inflation and interest ratesB.the economy always follows particular trendsC.the current economic problems are entirely predictableD.the present economic situation is better than expected(3).The text suggests that _.（分数
42、：1.00）A.the previous economic models are still applicableB.an extremely low jobless rate will lead to inflationC.a high unemployment rate will result from inflationD.interest rates have an immediate effect on the economy(4).By saying “This is no flash in the pan“ ( Para. 3 ), the author means that _
43、.（分数：1.00）A.the low inflation rate will continueB.the inflation rate will rise againC.inflation will disappear entirelyD.there is no inflation at present(5).How does the author feel about the present situation?（分数：1.00）A.Tolerant.B.Indifferent.C.Disappointed.D.Surprised.十、Text 3(总题数：1，分数：5.00)Proper
44、 arrangement of classroom space is important to encouraging interaction. Most of us have noticed how important physical setting is to efficiency and comfort when we work. Today“s corporations hire human engineering specialists and spend a great deal of time and money to make sure that the physical e
45、nvironments of buildings are fit to the activities of their inhabitants. Similarly, college classroom space should be designed to encourage the activity of critical thinking. We moved into the twenty-first century, but stepped into almost any college classroom and you would step back in time at leas
46、t a hundred years. Desks were normally in straight rows, so students could clearly see the teacher but not all their classmates. The assumption behind such an arrangement is obvious: everything important comes from the teacher. With a little imagination and effort, unless desks are fixed to the floo
47、r, the teacher can correct this situation and create space that encourages interchanges among students. In small or standardsized classes, chairs, desks and tables can be arranged in different ways: circles, U-shapes, or semicircles. The primary goal should be for everyone to be able to see everyone
48、 else. Larger classes, particularly those held in lecture halls, unfortunately, allow much less flexibility. Arrangement of the classroom should also make it easy to divide students into small groups for discussion or problem-solving exercises. Small classes with moveable desks and tables present no
49、 problem. Even in large lecture halls, it is possible for students to turn around and form groups of four to six. Breaking a class into small groups provides more opportunities for students to interact with each other, think out hard, and see how other students“ thinking processes operateall these are the most important elements in developing new modes of critical thinking. In courses that regularly use a small group format, students
