填空题A. Follow on Lines B. Whisper: Keep It to Yourself C. Word of Experience: Stick to It D. Code of Success: Freed and Targeted E. Efficient Work to Promote Efficient Workers F. Recipe: Simplicity Means Everything G. Efficiency Comes from Orders Every decade has its defining self-help business book. In the 1940s it was How to Win Friends and Influence People , in the 1990s The Seven Habits of Highly Successful People . These days we"re worried about something much simpler: Getting Things Done. 1 That"s the title of productivity guru David Allen"s pithy 2001 treatise on working efficiently, which continues to resonate in this decade"s overworked, overwhelmed, overteched workplace. Allen hasn"t just sold 500,000 copies of his book. He has preached his message of focus, discipline and creativity everywhere from Sony and Novartis to the World Bank and the U. S. Air Force. He counsels swamped chief executives on coping with information overload. He ministers to some clients with an intensive, two-day, $ 6,000 private session in which he and his team organize their lives from top to bottom. And he has won the devotions of acolytes who document on their blogs how his Getting Things Done (GTO) program has changed their lives. 2 Allen admits that much of his basic recipe is common sense. Free your mind, and productivity will follow. Break down projects and goals into discrete, definable actions, and you won"t be bothered by all those loose threads pulling at your attention. First make decisions about what needs to get done, and then fashion a plan for doing it. If you"ve catalogued everything you have to do and all your long-term goals, Allen says, you"re less likely to wake up at 3 a. m. worrying about whether you"ve forgotten something. "Most people haven"t realized how out of control their head is when they get 300 e-mails a day and each of them has potential meaning." 3 When e-mails, phones calls and to-do lists are truly under control, Allen says, the real change begins. You will finally be able to use your mind to dream up great ideas and enjoy your life rather than just occupy it with all the things you"ve got to do. Allen himself, despite running a $ 5.5 million consulting practice, traveling 200 days a year and juggling a business that"s growing 40% every years, finds time to joyride in his Mini Cooper and sculpt bonsai plants. Oh, and he had earned his black belt in karate. 4 Few companies have embraced Allen"s philosophy as thoroughly as General Mills, the Minnesota-based maker of Cheerios and Lucky Charms. Allen began at the company with a couple of private coaching sessions for top executives, who raved about his guidance. Allen and his staff now hold six to eight two-day training sessions a year. The company has already put more than 2,000 employees through GTD training and plans to expand it company wide. "Fads come and go," says Kevin Wilde, General Mills" CEO, "but this continues to work." 5 The most fevered followers of Allen"s organizational methodology gather online. Websites like gtdindex, marvelz, corn parse Allen"s every utterance. The 43 Folders blog ran an eight-part pod-cast interview with him. GTD enthusiasts like Frank Meeuwsen, on whatsthenextaction, com gather best practice techniques for implementing the book"s ideas. More than 60 software tools have been built specifically to supplement Allen"s system.

填空题从七个选项中挑选合适的内容，完成每个带数字的句子。 Text 1 We have to realize how old, how very old, we are. Nations are classified as "aged" when they have 7 per cent or more of their people aged 65 or above, and by about 1970 every one of the advanced countries had become like this. Of the really ancient societies, with over 13 per cent above 65, all are in Northwestern Europe. We know that we are getting even older, and that the nearer a society approximates to zero population growth, the older its population is likely to be--at least, for any future that concerns us now. To these now familiar facts a number of further facts may be added, some of them only recently recognized. There is the apparent paradox that the effective cause of the high proportion of the old is births rather than deaths. There is the economic principle that the dependency ratio--the degree to which those who cannot earn depend for a living on those who can--is more advantageous in older societies like ours than in the younger societies of the developing world, because lots of dependent babies are more of a liability than numbers of the inactive aged. There is the appreciation of the historical truth that the aging of advanced societies has been a sudden change. If "revolution" is a rapid resettlement of the social structure, and if the age composition of the society counts as a very important aspect of that social structure, then there has been a social revolution in European and particularly Western European society within the lifetime of everyone over 50. Taken together, these things have implications which are only beginning to be acknowledged. These facts and circumstances had a leading position at a world gathering about aging as a challenge to science and to policy, held at Vichy in France. There is often resistance to the idea that it is because the birth rate fell earlier in Western and Northwestern Europe than elsewhere, rather than because of any change in the death rate, that we have grown so old. Long life is altering our society, of course, but in experiential terms. We have among us a very much greater experience of continued living than any society that has ever preceded us anywhere, and this will continue. But too much of that lengthened experience, even in the wealthy West, will be experience of poverty and neglect, unless we do something about it. If you are in your thirties, you ought to be aware that you can expect to live nearly one third of the rest of your life after the age of 60. The older you are now, of course, the greater this proportion will be, and greater still if you are a woman. [A] experienced in poor conditions. [B] more likely to live longer. [C] discuss aging as a challenge both science and policy confronts. [D] these things have far-reaching implications. [E] the degree to which those non-earners rely on those earners. [F] the older its population tends to be. [G] the early drop in birth rate.

填空题 We are living in one of those periods in human history which are marked by revolutionary changes in all of man's ideas and values. It is a time when every one of us must look within himself to find what ideas, what beliefs, and what ideals each of us will live by. And unless we find these ideals, and unless we stand by them firmly, we have no power to overcome the crisis in which we in our world find ourselves. I believe in people, in sheer, unadulterated humanity. I believe in listening to what people have to say, in helping them to achieve the things which they want and the things which they need. Naturally, there are people who behave like beasts, who kill, who cheat, who lie and who destroy. But without a belief in man and a faith in his possibilities for the future, there can be no hope for the future, but only bitterness that the past has gone. I believe we must, each of us, make a philosophy by which we can live. There are people who make a philosophy out of believing in nothing. They say there is no truth, that goodness is simply cleverness in disguising your own selfishness. They say that life is simply the short gap in between an unpleasant birth and an inevitable death. There are others who say that man is born into evil and sinfulness and that life is a process of purification through suffering and that death is the reward for having suffered. I believe these philosophies are false. The most important thing in life is the way it is lived, and there is no such thing as an abstract happiness, an abstract goodness or morality, or an abstract anything, except in terms of the person who believes and who acts. There is only the single human being who lives and who, through every moment of his own personal living experience, is being happy or unhappy, noble or base, wise or unwise, or simply existing. The question is: How can these individual moments of human experience be filled with the richness of a philosophy which can sustain the individual in his own life? Unless we give part of ourselves away, unless we can live with other people and understand them and help them, we are missing the most essential part of our own human lives. There are as many roads to the attainment of wisdom and goodness as there are people who undertake to walk them. There are as many solid truths on which we can stand as there are people who can search them out and who will stand on them. There are as many ideas and ideals as there are men of good will who will hold them in their minds and act them in their lives. A. listening to people's opinions B. revolutionary changes C. being happy or unhappy D. the way it is lived E. we give part of ourselves away F. many roads to the attainment of wisdom G. as a short gap between birth and death

填空题(Alike) other forms of energy, natural gas (may be used) to (heat) homes, cook food, and even (run) automobiles.A. AlikeB. may be usedC. heatD. run

填空题Text 1 [A] Analyzing your own taste. [B] Being cautious when experimenting. [C] Finding a model to follow. [D] Getting the final look absolutely right. [E] Learning to be realistic. [F] Making regular conscious choices. When we meet people for the first time, we often make decisions about them based entirely on how they look. And, of course it's something that works both ways, for we too are being judged on our appearance. When we look good, we feel good, which in turn leads to a more confident and self-assured manner. People then pick up on this confidence and respond positively towards us. Undoubtedly, it's what's inside that's important, but sometimes we can send out the wrong signals simply by wearing inappropriate clothing or not spending enough time thinking about how others see us.

填空题The chief problem in coping with foreign motorists is not so much remembering that they are different from you, but that they are enormously variable. Cross a frontier without adjusting and you can be in deep trouble. One of the greatest gulfs separating the driving nations is the Atlantic Ocean. More precisely, it is the mental distance between the European and the American motorist, particularly the South American motorist. Compare, for example, an English driver at a set of traffic lights with a Brazilian. Very rarely will an Englishman try to anticipate the green light by moving off prematurely. You will find the occasional sharpie who watches for the amber to come up on the adjacent set of lights. However, he will not go until he receives the lawful signal. Brazilians view the thing quite differently. If, in fact, they see traffic lights at all, they regard them as a kind of roadside decoration. The natives of North America are much more disciplined. They demonstrate this in their addiction to driving in one lane and sticking to it even if it means settling behind some great truck for many miles. To prevent other drivers from falling into reckless ways, American motorists try always to stay close behind the vehicle in front which can make it impossible, when all the vehicles are moving at about 55 mph, to make a real lane change. European visitors are constantly falling into this trap. They return to the Old World still flapping their arms in frustration because while driving in the State in their car they kept failing to get off the highway when they wanted to and were swept along to the next city. However, one nation above all others lives scrupulously by its traffic regulations—the Swiss. In Switzerland, if you were simply to anticipate a traffic light, the chances are that the motorist behind you would take your number and report you to the police. What is more, the police would visit you; and you would be convicted. The Swiss take their rules of the road so seriously that a diver can be ordered to appear in court and charged for speeding on hearsay alone, and very likely found guilty. There are slight regional variations among the French, German and Italian speaking areas, but it is generally safe to assume that any ear bearing a CH sticker will be driven with a high degree of discipline.

填空题A. Benefiting from an earlier modelB. Important operative conditionsC. Examining the public confusionD. How it's all linked upE. Finding a suitable locationF. Comparing wind speeds in Australian citiesG. Matching operational requirements with considerations of appearance Harvest time in Esperance is constant. As long as the wind blows — which is pretty much all the time- nine identical synchronized wind turbines reap the benefits of the dependable winds that gust up around the southern coastline of Western Australia. These sleek, white, robot-like wind turbines loom up on the horizon forming part of Australia's first commercial wind farm. They're not only functional machines that help provide electricity for this secluded coastal town, but increasingly, they're also drawcards for curious tourists and scientists alike. Because of its isolation, Esperance is not linked to Western Power's grid which supplies electricity from gas-, coal- and oil-fired power stations to the widespread population of Western Australia. Before the wind turbines went in, Esperance's entire electricity needs were met by the diesel power station in town. 41. ______ The $5.8 million Ten Mile. Lagoon project is not Esperance's first wind farm. The success of a smaller, experimental wind farm, at a spot called Salmon Beach, encouraged the state's power utility to take Esperance wind seriously. Today, the wind turbines at Ten Mile Lagoon work in conjunction with the diesel power station, significantly reducing the amount of the town's electricity generated by expensive diesel power. 42. ______ The wind farm is connected to the power station by a 33-kilovolt powerline, and a radio link between the two, allows operators to monitor and control each wind turbine. The nine 225-kilowatt Vestas wind turbines produce a total generating capacity of two megawatts and provide around 12 percent of the energy requirements of Esperance and its surrounding districts. 43. ______ The power produced by a wind turbine depends on the size and efficiency of the machine and, of course, on the energy in the wind. The energy in the wind available to the wind turbines is proportional to wind speed cubed. Thus, the greater the wind speed, the greater the output of the turbine. In order to achieve optimum wind speeds, the right location is imperative. "You have to accept the nature of the beast," Mr. Rosser, Western Power's physicist said. "As surface dwellers our perceptions of wind speeds are bad. As you go higher, wind speed increases significantly." 44. ______ The most favorable wind sites are on gently sloping hills, away from obstructions like trees and buildings and where the prevailing winds are not blocked. Computer modeling was used to select the best site for Esperance's wind farm. Scientists were concerned not only with efficiency, but also with protecting the coastal health environment which is rich in plant life and home to tiny pygmy and honey-possums, and a host of bird species. In addition, the wind farm is adjacent to Esperance's popular scenic tourist drive. 45. ______ Strict erosion controls have been implemented and access to the wind farm is limited to selected viewing areas. The wind turbine towers are painted white and devoid of corporate logos or signage. According to Mr. Rosser there is something of a worldwide backlash against wind farms with regard to their visual impact. "But because wind turbines perform best in the most exposed positions, they will always be visible. There is a very real need to balance environmental and technical requirements. I think the Ten Mile Lagoon Wind Farm sets the standards for environmentally friendly developments." In fact, the project has become something of a tourist attraction in itself. Esperance shire president Ian Mickel said the wind turbines had been well accepted by locals. "We have watched the wind farm develop with great interest, and now we find visitors to Esperance are equally enthusiastic about it," he said. The aim now is to identify other remote locations where wind turbines will be a feasible means of supplementing existing power stations.
