In the U(27) /U of a wing, this would make possible a material that is dense, strong and load-bearing at one end, clos

It is like making bespoke materials, U(30) /U you can customise the physical properties of every cubic millimetre of a structure. The new technique combines existing technologies in a(n) U(31) /U way. It

Mark your answers on ANSWER SHEET 1.BText 1/BIf the various advocates of the conflicting options are all s

11、mart, experienced, and well-informed, why do they disagree so completely? Wouldnt they all have thought the issue through carefully and come to approximately the same “best“ conclusion? The answer to that crucial question lies in the structure of the human brain and the way it processes information.

12、 Most human beings actually decide before they think. When any human being executive, specialized expert, or person in the street encounters a complex issue and forms an opinion, often within a matter of seconds, how thoroughly has he or she explored the implications of the various courses of action

13、? Answer: not very thoroughly. Very few people, no matter how intelligent or experienced, can take inventory of the many branching possibilities, possible outcomes, side effects, and undesired consequences of a policy or a course of action in a matter of seconds. Yet, those who pride themselves on b

14、eing decisive often try to do just that. And once their brains lock onto an opinion, most of their thinking thereafter consists of finding support for it. A very serious side effect of argumentative decision making can be a lack of support for the chosen course of action on the part of the “losing“

15、faction. When one faction wins the meeting and the others see themselves as losing, the battle often doesnt end when the meeting ends. Anger, resentment, and jealousy may lead them to sabotage the decision later, or to reopen the debate at later meetings. There is a better way. As philosopher Aldous

16、 Huxley said, “It isnt who is right, but what is right, that counts. “ The structured-inquiry method offers a better alternative to argumentative decision making by debate. With the help of the Internet and wireless computer technology, the gap between experts and executives is now being dramaticall

17、y closed. By actually putting the brakes on the thinking process, slowing it down, and organizing the flow of logic, its possible to create a level of clarity that sheer argumentation can never match. The structured-inquiry process introduces a level of conceptual clarity by organizing the contribut

18、ions of the experts, then brings the experts and the decision makers closer together. Although it isnt possible or necessary for a president or prime minister to listen in on every intelligence analysis meeting, its possible to organize the experts information to give the decision maker much greater

19、 insight as to its meaning. This process may somewhat resemble a marketing focus group; its a simple, remarkably clever way to bring decision makers closer to the source of the expert information and opinions on which they must base their decisions. （分数：5.00）(1).From the first 3 paragraphs we can le

20、arn that _.（分数：1.00）A.executive, specialized expert, are no more clever than person in the street.B.very few people decide before they think.C.those who pride themselves on being decisive often fail to do soD.people tend to consider carefully before making decisions(2).Judging from the context, what

24、h Columbias rivers to spawn. And every spring new reports detail fresh disasters that befall them. This year is no different. The fisheries committee of Canada s House of Commons and a former chief justice of British Columbia, Bryan Williams, have just examined separately why 1. 3 m sockeye salmon m

25、ysteriously “disappeared“ from the famed Fraser river fishery in 2004. Their conclusions point to a politically explosive conflict between the survival of salmon and the rights of First Nations, as Canadians call Indians. In 2004, only about 524,000 salmon are thought to have returned to the spawnin

26、g grounds, barely more than a quarter the number who made it four years earlier. High water temperatures may have killed many. The House of Commons also lambasted the federal Department of Fisheries and Oceans (DFO) for poor scientific data, and for failing to enforce catch levels. Four similar repo

27、rts since 1992 have called for the departments reform. In vain. its senior officials are “in denial“ about its failings, said the committee. Mr Williams report added a more shocking twist. He concluded that illegal fishing on the Fraser river is “rampant and out of control“, with “no-go“ zones where

28、 fisheries of ricers are told not to confront Indian poachers for fear of violence. The judge complained that the DFO withheld a report by one of its investigators which detailed extensive poaching and sale of salmon by members of the Cheam First Nation, some of whom were armed. Some First Nations c

29、laim an unrestricted right to fish and sell their catch. Canadas constitution acknowledges the aboriginal right to fish for food and for social and ceremonial needs, but not a general commercial right. On the Fraser, however, the DFO has granted Indians a special commercial fishery. To some Indians,

30、 even that is not enough. Both reports called for more funds for the DFO, to improve data collection and enforcement. They also recommended returning to a single legal regime for commercial fishing applying to all Canadians. On April 14th, Geoff Regan, the federal fisheries minister, responded to tw

31、o previous reports from a year ago. One, from a First Nations group, suggested giving natives a rising share of the catch. The other proposed a new quota system for fishing licenses, and the conclusion of long-standing talks on treaties, including fishing rights, with First Nations. Mr Regan said hi

32、s department would spend this year consulting “stakeholders“ (natives, commercial and sport fishermen). It will also launch pilot projects aimed at improving conservation, enforcement and First Nations access to fisheries. （分数：5.00）(1).The “explosive conflict“ in Para 1 refers to _.（分数：1.00）A.salmon

33、s return to spawn and its survivalB.The fisheries committee of Canadas House of Commons and Bryan WilliamsC.the struggle between sockeye salmon and human beingsD.the collision between salmons survival and human fishery(2).The number of salmon every spring in British Columbias rivers four years earli

An increase in m

37、inority populations in a neighborhood would prompt a grocer with foresight to stock more foods linked to ethnic tastes. An art museum director with foresight might follow trends in computer graphics to make exhibits more appealing to younger visitors. Foresight may reveal potential threats that we c

38、an prepare to deal with before they become crises. For instance, a corporate manager with foresight might see an alarming rise in local housing prices that could affect the availability of skilled workers in the region. The publics changing values and priorities, as well as emerging technologies, de

39、mographic shifts, economic constraints (or opportunities), and environmental and resource concerns are all parts of the increasingly complex world system in which leaders must lead. People in government also need foresight to keep systems running smoothly, to plan budgets, and to prevent wars. Gover

40、nment leaders today must deal with a host of new problems emerging from rapid advances in technology. Even at the community level, foresight is critical: School officials, for example, need foresight to assess numbers of students to accommodate, numbers of teachers to hire, new educational technolog

41、ies to deploy, and new skills for students (and their teachers) to develop. Many of the best-known techniques for foresight were developed by government planners, especially in the military, when the post-World War atomic age made it critical to “think about the unthinkable“ and prepare for it. Pion

42、eering futurists at the RAND Corporation (the first “think tank“) began seriously considering what new technologies might emerge in the future and how these might affect U.S. security. These pioneering futurists at RAND, along with others elsewhere, refined a variety of new ways for thinking about t

43、he future. The futurists recognized that the future world is continuous with the present world, so we can learn a great deal about what may happen in the future by looking systematically at what is happening now. The key thing to watch is not events (sudden developments or one-day occurrences) but t

44、rends (long-term ongoing shifts in such things as population. land use, technology, and governmental systems). Using these techniques and many others, futurists now can tell us many things that may happen in the future. Some are nearly certain to happen, such as the continuing expansion in the world

45、s population. Other events are viewed as far less likely, but could be extremely important if they do occur, such as an asteroid colliding with the planet. （分数：5.00）(1).Correctly exercising foresight is shown in the case of _.（分数：1.00）A.new products and servicesB.an increase in minority populationsC
