18、ics, 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 portraying relationships and _27_ connections. Graphics are used extensively in natural sciences and social sciences. Social scientists work with statistics _28

19、_ 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 information easier for the student to grasp, but as an integral part of the way social scientists think. Many textbooks, _29_ those in economics, contain appendixe

20、s that provide specific information on reading and working with graphic material. Make it a practice to _30_ attentively the titles, captions, headings, and other material connected with graphics. These elements _31_ and usually explain what you are looking at. When you are examining graphics, the _

21、32_ questions to ask are (a) What is this items about? and (b) What key idea is the author _33_ . One warning: Unless you integrate your reading of graphics 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 n

22、ot 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_ that most of the firstborn children in the sample were from single-parent homes in which the father was absent. （分数：71.50）填空项 1:_填空项 1:_填空项

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 in

24、creased risk of brain and behavioral disorders in children. The developing 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 environmen

25、tal _38_ have long urged US government agencies to _39_ the use of some 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 h

26、omes and child-care _41_ , after concerns were raised about lead poisoning. 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 childrens brain and behavioral disorders, like hyperactivity and lower grades, can als

27、o be linked to social and genetic factors, its tough to pin 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, i

While it may be impossible to prevent kids from drinking tap water that may contain trace amounts of chemicals, keeping kids away from lawns recently sprayed with chemicals and freshly dry-cleaned clothes cant hurt.

Whethe

31、r it is a transition 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

32、 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 moving), 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

33、. B) 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 (大圆石), it pushes you back. Once you have started the

34、boulder 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 is hard

35、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 (动能) to your own body, or you can approach alongside and slowly apply pressure to gradually alter his course. C) But there are

36、other kinds of momentum as well. After all, we dont speak only of objects or people as having momentum; we speak of entire systems having 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 directi

37、on. D) One kind of momentum is technological momentum. When a technology is deployed, its impacts reach far beyond itself. Consider the incandescent (白炽灯的) bulb, an object currently hated by many environmentalists and energy-efficiency advocates. The incandescent light bulb, invented by Thomas Ediso

38、n, 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 easy, with all t

39、hat 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 your grandmoth

40、er, 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 the devices tha

41、t 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 sources, only ba

42、d applications.“ There are some very commendable characteristics of the CFL compact fluorescent(荧光的) light bulb, yet the selection of any light source 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 t

43、o 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 fixture with the room. It i

44、s 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 inexpensive proposition. H)

45、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 30 percent of our elect

46、ricity 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 new energy industry ar

47、e 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 trained in the right sequenc

48、e. 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 another 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 that have lengt
