21、In this section, you will hear a passage three times. When the passage is read for the first time, you should listen carefully for its general idea. When the passage is read for the second time, you are required to fill in the blanks with the exact words you have just heard. Finally, when the passag

22、e is read for the third time, you should check what you have written.Graphics are used in textbooks as part of the language of the discipline, as in math or economics, or as study aids. Authors use graphic aids to（26）and expand on concepts taken up in the text because graphics are yet another way of

23、 portraying relationships and（27）connections.Graphics are used extensively in natural sciences and social sciences. Social scientists work with statistics（28）data, and the best way to present these statistics is often in graphic form. Graphics are included- not merely as a means of making the inform

24、ation easier for the student to grasp, but as an integral part of the way social scientists think. Many textbooks,（29）those in economics, contain appendixes that provide specific information on reading and working with graphic material.Make it a practice to（30）attentively the titles, captions, headi

25、ngs, and other material connected with graphics. These elements（31）and usually explain what you are looking at. When you are examining graphics, the（32）questions to ask are (a.)What is this item about? and (b.)What key idea is the author（33）?One warning: Unless you integrate your reading of graphics

26、 with the text, you may make a wrong assumption.（34）, from a chart indicating that 33 percent of firstborn children in a research sample did not feel close to their fathers, you might assume that some dreadful influence was at work on the firstborn children. However, a careful reading of the text（35

27、）that most of the firstborn children in the sample were from single-parent homes in which the father was absent.Part Reading Comprehension (40 minutes)Section ADirections: In this section, there is a passage with ten blanks. You are required to select one word for each blank from a list of choices g

28、iven in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in

29、 the bank more than once.Questions 36 to 45 are based on the following passage.According to a report from the Harvard School of Public Health, many everyday products, including some bug sprays and cleaning fluids, could lead to an increased risk of brain and behavioral disorders in children. The dev

30、eloping brain, the report says, is particularly （36） to the toxic effects of certain chemicals these products may contain, and the damage they cause can be（37） .The official policy, however, is still evolving. Health and environmental（38） have long urged U.S. government agencies to （39） the use of s

31、ome of the 11 chemicals the report cites and called for more studies on their long-term effects. In 2001, for example, the Environmental Protection Agency （40） the type and amount of lead that could be present in paint and soil in homes and child-care（41）, after concerns were raised about lead poiso

32、ning. The agency is now （42） the toxic effects of some of the chemicals in the latest report. But the threshold for regulation is high. Because children's brain and behavioral disorders, like hyperactivity and lower grades, can also be linked to social and genetic factors, it's tough to pin

33、them on exposure to specific chemicals with solid （43）evidence, which is what the EPA requires. Even the Harvard study did not prove a direct （44） but noted strong associations between exposure and risk of behavioral issues.Nonetheless, it's smart to （45） caution. While it may be impossible to p

Eachstatement contains information given in one of the paragraphs. Identify the paragraph from which the informat

36、ion is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter. Answer the questions by marking the corresponding letter on Answer Sheet 2.The Impossibility of Rapid Energy Transitions A Politicians are fond of promising rapid energy transitions. Whether it is a tr

37、ansition from imported to domestic oil or from coal-powered electricity production to natural-gas power plants, politicians love to talk big. Unfortunately for them (and often the taxpayers), our energy systems are a bit like an aircraft carrier: they are unbelievably expensive, they are built to la

38、st for a very long time, they have a huge amount of inertia ( meaning it takes a lot of energy to set them moving ), and they have a lot of momentum once they are set in motion. No matter how hard you try, you can't turn something that large on a dime ( 10美分硬幣 ), or even a few thousand dimes. B

39、In physics, moving objects have two characteristics relevant to understanding the dynamics of energy systems: inertia and momentum. Inertia is the resistance of objects to efforts to change their state of motion. If you try to push a boulder ( 大圓石 ), it pushes you back. Once you have started the bou

40、lder rolling, it develops momentum, which is defined by its mass and velocity. Momentum is said to be "conserved," that is, once you build it up, it has to go somewhere. So a heavy object, like a football player moving at a high speed, has a lot of momentum-that is, once he is moving, it i

41、s hard to change his state of motion. If you want to change his course, you have only a few choices: you can stop him, transferring ( possibly painfully) some of his kinetic energy (動能) to your own body, or you can approach alongside and slowly apply pressure to gradually alter his course. C But the

42、re are other kinds of momentum as well. After all, we don't speak only of objects or people as having momentum; we speak of entire systems having momentum. Whether it's a sports team or a presidential campaign, everybody relishes having the big momentum, because it makes them harder to stop

43、or change direction. D One kind of momentum is technological momentum. When a technology is deployed, its impacts reach far beyond itself. Consider the incandescent (白熾燈的) bulb, an object currently hated by many environmentalists and energy-efficiency advocates. The incandescent light bulb, invented

44、 by Thomas Edison, which came to be the symbol of inspiration, has been developed into hundreds, if not thousands, of forms. Today, a visit to a lighting store reveals a stunning array of choices. There are standard-shaped bulbs, flame-shaped bulbs, colored globe-shaped bulbs, and more. It is quite

45、easy, with all that choice, to change a light bulb. E But the momentum of incandescent lighting does not stop there. All of those specialized bulbs led to the building of specialized light fixtures, from the desk lamp you study by, to the ugly but beloved hand-painted Chinese lamp you inherited from

46、 your grandmother, to the ceiling fixture in your closet, to the light in your oven or refrigerator, and to the light that the dentist points at you. It is easy to change a light bulb, sure, but it is harder to change the bulb and its fixture. F And there is more to the story, because not only are t

47、he devices that house incandescent bulbs shaped to their underlying characteristics, but rooms and entire buildings have been designed in accordance with how incandescent lighting reflects off walls and windows. G As lighting expert Howard Brandston points out, “ Generally, there are no bad light so

48、urces, only bad applications. " There are some very commendable characteristics of the CFL compact fluorescent (熒光的) light bulb , yet the selection of any light source remains inseparable from the luminaire (照明裝置 ) that houses it, along with the space in which both are installed, and lighting r

49、equirements that need to be satisfied. The lamp, the fixture, and the room, all three must work in concert for the true benefits of end-users. If the CFL should be used for lighting a particular space, or an object within that space, the fixture must be designed to work with that lamp, and that fixt

50、ure with the room. It is a symbiotic (共生的 ) relationship. A CFL cannot be simply installed in an incandescent fixture and then expected to produce a visual appearance that is more than washed out, foggy, and dim. The whole fixture must be replaced-light source and luminaire-and this is never an inex

51、pensive proposition. H And Brandston knows a thing or two about lighting, being the man who illuminated the Statue of Liberty. I Another type of momentum we have to think about when planning for changes in our energy systems is labor-pool momentum. It is one thing to say that we are going to shift 3

52、0 percent of our electricity supply from, say, coal to nuclear power in 20 years. But it is another thing to have a supply of trained talent that could let you carry out this promise. That is because the engineers, designers, regulators, operators, and all of the other skilled people needed for the

53、new energy industry are specialists who have to be trained first ( or retrained, if they are the ones being laid off in some related industry), and education, like any other complicated endeavor, takes time. And not only do our prospective new energy workers have to be trained, they have to be train

54、ed in the right sequence. One needs the designers, and perhaps the regulators, before the builders and operators, and each group of workers in training has to know there is work waiting beyond graduation. In some cases, colleges and universities might have to change their training programs,adding an

55、other layer of difficulty. J By far the biggest type of momentum that comes into play when it comes to changing our energy systems is economic momentum. The major components of our energy systems, such as fuel production, refining, electrical generation and distribution, are costly installations tha

56、t have lengthy life spans. They have to operate for long periods of time before the costs of development have been recovered. When investors put up money to build, say, a nuclear power plant, they expect to earn that money back over the planned life of the plant, which is typically between 40and 60

57、years. Some coal power plants in the United States have operated for more than 70 years!The oldest continuously operated commercial hydro-electric plant in the United States is on New York's Hudson River, and it went into commercial service in 1898. K As Vaclav Smil points out, "All the for

58、ecasts, plans, and anticipations cited above have failed so miserably because their authors and promoters thought the transitions they hoped to implement would proceed unlike all previous energy transitions, and that their progress could be accelerated in an unprecedented manner. " L When you hear people speaking of making a rapid transition toward any type of energy, whether it is a switch from coal to nuclear power, or a switch from gasoline-powered cars to electric cars, or even a switch. from an incandescent to a fluorescent
