单选题请根据下面短文回答第66～70题： One day Jack's wife was cleaning the house. "Look at all these umbrellas (雨伞) ," Jack's wife said to him. "There are eight and they are broken." "I'll take them all to the umbrella shop. Maybe the workers there can mend them, "Jack said. "They are too good to throw away." Jack took the eight umbrellas to the shop and left them there. "They'll be ready tomorrow, "the shopkeeper said. That evening Jack went home from the office by bus as usual. He sat next to an old woman. She had a red umbrella on the floor near her. When the bus reached his stop, he picked up her umbrella and stood up. "Hey!" the woman said. "That's my umbrella." "I'm sorry, "Jack said, giving it to her. "I wasn't thinking. Please forgive(原谅)me." The next day he took the umbrellas from the umbrella shop and got on the bus. As he sat down, a woman behind him said, "You have certainly had a successful(成功的)day!" He turned around and saw the woman he had seen the day before.

单选题Sustainable development is applied to just about everything from energy to clean water and economic growth, and as a result it has become difficult to question either the basic assumptions behind it or the way the concept is put to use. This is especially true in agriculture, where sustainable development is often taken as the sole measure of progress without a proper appreciation of historical and cultural perspectives. To start with, it is important to remember that the nature of agriculture has changed markedly throughout history, and will continue to do so medieval agriculture in northern Europe fed, clothed and sheltered a predominantly rural society with a much lower population density than it is today. It had minimal effect on biodiversity, and any pollution it caused was typically localized. In terms of energy use and the nutrients captured in the product it was relatively inefficient. Contrast this with farming since the start of the industrial revolution. Competition from overseas led farmers to specialize and increase yields. Throughout this period food became cheaper, safe and more reliable. However, these changes have also led to habitat (栖息地) loss and to diminishing biodiversity. What"s more, demand for animal products in developing countries is growing so fast that meeting it will require an extra 300 million tons of grain a year by 2050 yet the growth of cities and industry is reducing the amount of water available for agriculture in many regions. All this means that agriculture in the 21stcentury will have to be very different from how it was in the 20th.thiswill require radical thinking. For example, we need to move away from the idea that traditional practices are inevitably more sustainable than new ones. We also need to abandon the notion that agriculture can be "zero impact". The key will be to abandon the rather simple and static measures of sustainability, which centre on the need to maintain production without increasing damage. Instead we need a more dynamic interpretation, one that looks at the pros and cons (正反两方面) of all the various way land is used. There are many different ways to measure agricultural performance besides food yield: energy use, environmental costs, water purity, carbon footprint and biodiversity. It is clear, for example, that the carbon of transporting tomatoes from Spain to the UK is less than that of producing them in the UK with additional heating and lighting. But we do not know whether lower carbon footprints will always be better for biodiversity. What is crucial is recognizing that sustainable agriculture is not just about sustainable food production.

单选题People in business can use foresight to identify new products and services, as well as markets for those products and services. An increase in minority 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 can 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 public's changing values and priorities, as well as emerging technologies, demographic 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. Government 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 technologies 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 Ⅱ atomic age made it critical to "think about the unthinkable" and prepare for it. Pioneering 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 the 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 trends (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'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.

单选题With Airbus's giant A380 airliner about in to take to the skies, you might think planes could not get much bigger — and you would be right. For a given design, it turns (21) , there comes a point where the wings become too heavy to generate (22) lift to carry their own weight. (23) a new way of designing and making materials could (24) that problem. Two engineers (25) University College London have devised an innovative way to customise and control the (26) of a material throughout its three-dimensional structure. In the (27) of a wing, this would make possible a material that is dense, strong and load-bearing at one end, close to the fuselage, (28) the extremities could be made less dense, lighter and more (29) . It is like making bespoke materials, (30) you can customise the physical properties of every cubic millimetre of a structure. The new technique combines existing technologies in a(n) (31) way. It starts by using finite-element-analysis software, of the type commonly used by engineers, (32) a virtual prototype of the object. The software models the stresses and strains that the object will need to (33) throughout its structure. Using this information it is then (34) to calculate the precise forces acting on millions of smaller subsections of the structure. (35) of these subsections is (36) treated as a separate object with its own set of forces acting on it — and each subsection (37) for a different microstructure to absorb those local forces. Designing so many microstructures manually (38) be a huge task, so the researchers apply an optimisation program, called a genetic algorithm, (39) This uses a process of randomization and trial-and-error to search the vast number of possible microstructures to find the most (40) design for each subsection.
