Authors use graphic a
17、ids to【B1】_and expand on concepts taken up in the text because graphics are yet another way of portraying relationships and【B2】_connections.Graphics are used extensively in natural sciences and social sciences. Social scientists work with statistics【B3】_data, and the best way to present these statis
18、tics is often in graphic form. Graphics are included not merely as a means of making the information easier for the student to grasp, but as an integral part of the way social scientists think. Many textbooks,【B4】_those in economics, contain appendixes that provide specific information on reading an
19、d working with graphic material.Make it a practice to【B5】_attentively the titles, captions, headings, and other material connected with graphics. These elements【B6】_and usually explain what you are looking at. When you are examining graphics, the【B7】_questions to ask are(a)What is this item about? a
20、nd(b)What key idea is the author【B8】_?One warning: Unless you integrate your reading of graphics with the text, you may make a wrong assumption.【B9】_, 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 dr
21、eadful influence was at work on the firstborn children. However, a careful reading of the text【B10】_that most of the firstborn children in the sample were from single-parent homes in which the father was absent.27 【B1 】28 【B2 】29 【B3 】30 【B4 】31 【B5 】32 【B6 】33 【B7 】34 【B8 】35 【B9 】36 【B10 】Section

The developing brain, the report says, is particularly【C1】_to the toxic effects of
23、 certain chemicals these products may contain, and the damage they cause can be【C2】_.The official policy, however, is still evolving. Health and environmental【C3 】_have long urged U.

In 2001, for example, the Environmental Protection Agency【C5】_the type and amount of lead that could be present in paint and soil in homes and child-care【C6】_, after concerns were raised about lead poisoning. The agency is now【C7】 _the toxic effects of some of the chemicals in

Because childrens brain and behavioral disorders, like hyperactivity and lower grades, can also be linked to social and genetic factors, its tough to pin them on exposure to specific chemicals with solid【 C8】_evidence, which is what the EP

Whether it is a transition from imported to domestic oil or from coal-powered electricity production to natural-gas power pl
29、ants, 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 last for a very long time, they have a huge amount of inertia(meaning it takes a lot of energy to set them mo
30、ving), and they have a lot of momentum once they are set in motion. No matter how hard you try, you cant turn something that large on a dime(10 美分硬币), or even a few thousand dimes.BIn physics, moving objects have two characteristics relevant to understanding the dynamics of energy systems: inertia a
31、nd momentum. Inertia is the resistance of objects to efforts to change their state of motion. If you try to push a boulder(大圆石), it pushes you back. Once you have started the boulder rolling, it develops momentum, which is defined by its mass and velocity. Momentum is said to be “conserved,“ that is
32、, 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 momentumthat is, once he is moving, it is 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(p
33、ossibly painfully)some of his kinetic energy(动能)to your own body, or you can approach alongside and slowly apply pressure to gradually alter his course.CBut there are other kinds of momentum as well. After all, we dont speak only of objects or people as having momentum: we speak of entire systems ha
34、ving momentum. Whether its a sports team or a presidential campaign, everybody relishes having the big momentum, because it makes them harder to stop or change direction.DOne kind of momentum is technological momentum. When a technology is deployed, its impacts reach far beyond itself. Consider the
35、incandescent(白炽灯的)bulb, an object currently hated by many environmentalists and energy-efficiency advocates. The incandescent light bulb, invented 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
36、store reveals a stunning array of choices. There are standard-shaped bulbs, flame-shaped bulbs, colored globe-shaped bulbs, and more. It is quite easy, with all that choice, to change a light bulb.EBut the momentum of incandescent lighting does not stop there. All of those specialized bulbs led to t
37、he building of specialized light fixtures, from the desk lamp you study by, to the ugly but beloved hand-painted Chinese lamp you inherited from 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
38、easy to change a light bulb, sure, but it is harder to change the bulb and its fixture.FAnd there is more to the story, because not only are the devices that house incandescent bulbs shaped to their underlying characteristics, but rooms and entire buildings have been designed in accordance with how
39、incandescent lighting reflects off walls and windows.GAs lighting expert Howard Brandston points out, “Generally, there are no bad light sources, only bad applications. “ There are some very commendable characteristics of the CFLcompact fluorescent(荧光的)light bulb, yet the selection of any light sour
40、ce remains inseparable from the luminaire(照明装置)that houses it, along with the space in which both are installed, and lighting requirements 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
41、lighting a particular space, or an object within that space, the fixture must be designed to work with that lamp, and that fixture 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 m
42、ore than washed out, foggy, and dim. The whole fixture must be replacedlight source and luminaireand this is never an inexpensive proposition.HAnd Brandston knows a thing or two about lighting, being the man who illuminated the Statue of Liberty.IAnother type of momentum we have to think about when
43、planning for changes in our energy systems is labor-pool momentum. It is one thing to say that we are going to shift 30 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
44、. That is because the engineers, designers, regulators, operators, and all of the other skilled people needed for the 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 complicate
45、d endeavor, takes time. And not only do our prospective new energy workers have to be trained, they have to be trained 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 waitin
46、g beyond graduation. In some cases, colleges and universities might have to change their training programs, adding another layer of difficulty.JBy 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 ener
47、gy systems, such as fuel production, refining, electrical generation and distribution, are costly installations that 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
48、plant, they expect to earn that money back over the planned life of the plant, which is typically between 40 and 60 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
49、 Yorks Hudson River, and it went into commercial service in 1898.KAs Vaclav Smil points out, “All the forecasts, 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. “LWhen you hear people speaking of making a rapid transition to
