单选题Here are two elements in life that Americans do save carefully: time and labor. Americans are "slaves to nothing but the clock", it has been said. Time is treated as if it were an almost tangible entry. In their language, there are words associated with it; time can be budgeted, saved, wasted, stolen, killed, and cut. Americans also charge for time. It is a precious commodity to them. Many people have a rather acute sense of the shortness of each lifetime. Once the sands have run out of a person"s hourglass, they cannot be replaced. They want every minute to count. Since people value time highly, they hate someone else "wasting" it beyond a certain courtesy point. This affects the matter of patience. In the American system of values, patience is not a high priority. Many of them have what might be called "a short fuse". They begin to splutter and move restlessly about if they feel time is slipping away without some return—be this in terms of pleasure, work value or rest. Normally Americans do not assess their visitors in relaxed surroundings over prolonged small talk; much less do they take out for dinner, while they develop a pre-business sense of trust and rapport. Rapport to most of them is less important than performance. They seek out credentials of past performance rather than evaluating a business colleague through social manners. Since they generally assess and probe professionally rather than socially, they start talking business very quickly. Most Americans live in time segments by engagement calendars. These calendars may be divided into intervals as short as fifteen minutes. They often "give" a person two or three (or more) segments of their calendar, but in the business world they almost always have other appointments following hard on the heels of whatever they are doing. Time is therefore always ticking in their inner ear.

单选题Small, pink and very ugly. Hardly the qualities of a star, but they describe the deformed mouse that was the media darling at a recent science exhibition in Beijing. With a complex tissue structure in the shape of a human ear grafted on to its back, the rosy rodent was a stunning symbol of the serious strides China is making in the field of biotechnology. China is fast applying the latest life-science techniques learned from the West to aggressively pursue genome research. It's establishing its own centers of technical excellence to build a scientific base to compete directly with the United States and Europe. With a plentiful supply of smart young scientists at home and lots of interest abroad biotechnology is on the brink of a boom in China. And in the view of foreign scientists, Beijing is playing a clever hand, maximizing the opportunities open to them. For the moment, the cooperation exists mostly with Europe and the U.S. But Asia's other biotech leaders, Japan, Singapore and Korea, also are recognizing China's potential as an attractive low-cost base to conduct research. These partnerships——and China's advancement in the field of biotechnology——could help benefit the rest of Asia: China's rapid progress in improving crop yields will address food-security concerns in the region. In addition, China is more likely to focus on developing cheap technology that its predominantly poor population——and those of other Asian countries——can afford. There remain, however, serious barriers to the development of a strong biotech industry. Among them are a poor domestic legal framework, weak enforcement of intellectual-property rights and loose adherence to international standards. China is a signatory of the International Bio Safely Protocol, which should mean adherence to global standards governing the conduct of field trials. But some observers are skeptical. "The regulations look good, but I haven't met one scientist who believes they are being fully adhered to," says a European science analyst. If shortcuts are taken, then some of the recent scientific achievements trumpeted in the official press may never make it to market. But no matter how strict lab test are, other problems lie in wait. For example, there is a number of tasks it would take years to fulfill in the patents office, says one lawyer, leaving innovators with little protection if they take a product to market in China.

单选题Does ______ matter if he can"t finish the job in time?

单选题"If you want to see a thing well, reach out and touch it!" That may seem a strange thing to say. But touching things can help you to see them better. Your eyes can tell you that a glass ball is round. But by holding it in your hands, you can feel how smooth and cool the ball is. You can feel how heavy the glass is. When you feel all these about the ball, you really see it. With your skin, you can feel better. For example, your fingers can tell the difference between two coins in your pocket. You can feel a little drop of water on the back of your hand, too. All children soon learn what "Don"t touch!" means. They hear it often. Yet most of us keep on touching things as we grow up. In shops, we touch things as we might buy: food, clothes. To see something well, we have to touch it. There are ways of learning to see well by feeling. One way is to close your eyes and try to feel everything that is touching your skin. Feel the shoes on your feet, the clothes on your body, the air on your skin. At first, it is not easy to feel these things. You are too used to them! Most museums are just for looking. But today some museums have some things to touch. Their signs say, "Do touch!" There you can feel everything on show. If we want to see better, reach out and touch. Then you will really see!

单选题Invention and innovation have been quintessentially American pursuits from the earliest days of the republic. Benjamin Franklin was a world-famous scientist and inventor. Cyrus McCormick and his harvester, Samuel F. B. Morse and the telegraph, Alexander Graham Bell and the telephone—the 19th century produced a string of inventors and their world-changing creations. And then there was the greatest of them all, Thomas Alva Edison. He came up with the crucial devices that would give birth to three enduring American industries:electrical power, recorded music and motion pictures. Much of the world we live in today is a legacy of Edison and of his devotion to science and innovation. Edison taught us to invent, and for decades we were the best in the world. But today, more than 160 years after Edison's birth, America is losing its scientific edge. A landmark report released in May by the National Science Board lays out the numbers:while U. S. investment in R&D as a share of total GDP has remained relatively constant since the mid-1980s at 2.7% , the federal share of R&D has been consistently declining—even as Asian nations like Japan and South Korea have rapidly increased that ratio. At the same time, American students seem to be losing interest in science. Only about one-third of U. S. bachelor's degrees are in science or engineering now, compared with 63% in Japan and 53% in China. It's ironic that nowhere is America's position in science and technology more threatened than in the industry that Edison essentially invented: energy. Clean power could be to the 21st century what aeronautics and the computer were to the 20th, but the U. S. is already falling behind. Meanwhile, Congress remains largely paralyzed. Though in May the House of Representatives was finally able to pass the $ 86 billion America Competes Reauthorization Act, which would double the budgets of the National Science Foundation (NSF) and Energy Department's Office of Science, the bill's fate is cloudy in the deadlocked Senate. "At this rate... we'll be buying most of our wind generators and photovoltaic panels from other countries, " former NSF head Arden L. Bement said at a congressional hearing recently. "That's what keeps me awake sometimes at night. " Some erosion of the U. S. 's scientific dominance is inevitable in a globalized world and might not even be a bad thing. Tomorrow's innovators could arise in Shanghai or Seoul or Bangalore. And Edison would counsel against panic—as he put it once, " Whatever setbacks America has encountered, it has always emerged as a stronger and more prosperous nation. " But the U. S. will inevitably decline unless we invest in the education and research necessary to maintain the American edge. The next generation of Edisons could be waiting. But unless we move quickly, they won't have the tools they need to thrive.

单选题Despite a cooling of the economy, high-technology companies are still crying out for skilled workers. The Information Technology Association of America projects that more than 800, 000 technology jobs will go unfilled next year. The lack of qualified workers poses a huge threat to the U. S. economy. The most commonly cited reason for this state of affairs is that the country's agrarian-age (农村时代) education system fails to prepare students in the primary and secondary grades for the 21st century work. Yet an inadequate and outmoded education system is only part of the problem. A less tangible (明确的) but equally powerful cause is an antique (过时的) classification system that divides the workforce into two camps; white-collar knowledge workers and blue-collar manual laborers. Blue-collar workers emerged in the United States during the Industrial Age as work moved from farms to factories. White-collar office workers became a significant class in the twentieth century, outnumbering(多于) the blue-collar workers by mid-century. Corporations increasingly require a new layer of knowledge worker; a highly skilled multi-disciplined talent, who combines the mind of the white-collar worker with a solid grounding in mathematics and science ( physics, chemistry, and biology). These "gold-collar" workers—so named for their contributions to their companies and to the economy as well as for their personal earning ability—apply their knowledge to technology. The gold-collar worker already exists in a wide range of jobs. The maintenance technician who tests and repairs aircraft systems at American Airlines; the network administrator who manages systems and network operations at Procter the engineering technologist who assists scientists at Sandia National Laboratories; and the advanced-manufacturing technician at Intel can all be regarded as gold-collar workers.
