问答题It is hard to predict how science is going to turn out, and if it is really good science it is impossible to predict. If the things to be found are actually new, they are by definition unknown in advance. You cannot make choices in this matter. 1 You either have science or you don"t, and if you have it you are obliged to accept the surprising and disturbing pieces of information, along with the neat and promptly useful bits. The only solid piece of scientific truth about which I feel totally confident is that we are profoundly ignorant about nature. Indeed, I regard this as the major discovery of the past hundred years of biology. It is, in its way, an illuminating piece of news. 2 It would have amazed the brightest minds of the 18th century Enlightenment to be told by any of us how little we know and how bewildering the wag ahead seems. 3 It is this sudden confrontation with the depth and scope of ignorance that represents the most significant contribution of the 20th century science to the human intellect. In earlier times, we either pretended to understand how things worked or ignored the problem, or simply made up stories to fill the gaps. Now that we have begun exploring in earnest, we are getting glimpses of how huge the questions are, and how far from being answered. Because of this, we are depressed. 4 It is not so bad being ignorant if you are totally ignorant; the hard thing is knowing in some detail the reality of ignorance, the worst spots and here and there the not-so-bad spots, but no true light at the end of the tunnel nor even any tunnels that can yet be trusted. But we are making a beginning and there ought to be some satisfaction. There are probably no questions we can think up that can"t be answered, sooner or later, including even the matter of consciousness. 5 To be sure, there may well be questions we can"t think up, ever, and therefore limits to the reach of human intellect, but that is another matter. Within our limits, we should be able to work our way through to all our answers if we keep at it long enough, and pay attention.

问答题71. Not so long ago it was assumed that the dangers man would meet in space would be terrible, the main ones being radiation and. the danger of being hit by meteors. It is perhaps worth remembering that less than two centuries ago, the dangers of train travel seemed similarly terrible. A man would certainly die, it was thought, if carried along at a Speed of 30 miles per hour. There are two sorts of radiation man must fear in space. The first is radiation from the sun, and this is particularly dangerous when the sun is very active and explosions are occurring on its surface. The second, less harmful form comes from the so-called Van Allen Belts. These are two areas of radiation about 1 ,500 miles away from the earth. 72. Neither of these forms of radiation are a danger to us on the earth, since we are protected by our atmosphere. Specifically, it is that part of our atmosphere known as the ozonosphere which protects us. This is a belt of the chemical ozone between 12 and 21 miles from the ground which absorbs all the radiation. Once outside the atmosphere, however, man is no longer protected, and radiation can be harmful in a number of ways. 73. A distinction must be drawn between the short-and long-term effects of radiation. The former are merely unpleasant, but just because an astronaut returning from a journey in space does not seem to have been greatly harmed, we cannot assume that he is safe. The long-term effects can be extremely serious, even leading to death. One solution to the dangers of radiation is to protect the spaceship by putting some kind of shield around it. This was in fact done on the Apollo spaceships which landed on the moon. But this solution is not possible for longer journeys—to Mars for example—because the shield would need to be very large, and could not be carried. Another solution, not in fact possible at present, would be to surround the spaceship with a magnetic field to deflect the radiation. In all, we have to conclude that there is at present no complete solution to the problem of radiation.

问答题People tend to amass possessions. Indeed they can have a delightful surprise when they find something useful which they did not know they owned. Some people leave unwanted objects in drawers, cupboards and attics for years, in the belief that they may one day need just those very things. Collecting as a serious hobby is quite different. It provides relaxation for leisure hours, because just looking at one"s treasures is always a joy. One does not have to go out for amusement, since the collection is housed at home. Whatever it consists of, stamps, first editions of books, antique furniture, stuffed birds, toy animals, there is always something to do in connection with it, from finding the right place for the latest addition to verifying facts in reference books. This hobby educates one not only in the chosen subject, but also in general matters which have some bearing on it.

问答题{{B}}1{{/B}} Engineering is the professional art of applying science to the optimum conversion of the re- sources of nature to the uses of humankind. Engineering has been defined as the creative application of "scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination." The term engineering is sometimes more loosely defined, especially in Great Britain, as the manufacture or assembly of engines, ma- chine tools, and machine parts. Associated with engineering is a great body of special knowledge; preparation for professional practice involves extensive training in the application of that knowledge. The function of the scientist is to know, while that of the engineer is to do. The scientist adds to the store of verified, systematized knowledge of the physical world; the engineer brings this knowledge to bear on practical problems. Engineering is based principally on physics, chemistry, and mathematics and their extensions into materials science, solid and fluid mechanics, thermodynamics, and systems analysis.

问答题After working 36-hour shifts as a resident in orthopaedic surgery, Taryn Rose knew a lot about sore feet. But unlike most of her colleagues, she turned her pain into profit. Today she is CEO of Taryn Rose International, a $28 million company that makes chic, and comfortable, shoes. A Vietnamese refugee who moved to the United States when she was just eight, Rose assumed she"d follow in the footsteps of her physician father. For a while, she did, getting her medical degree from the University of Southern California and opting for gruelling training in orthopaedic surgery. But when the time came to apply for post-residential fellowships, Rose found her heart was no longer in medicine. "I felt like a part of me, the part that loves to learn new things, that likes adventure, would be dying." Rose had always loved shoes, especially high heels. When her fellow residents headed home after long hours on their feet, "I would make my way to Neiman Marcus for some retail therapy," she says. What if, she wondered, she gave up her career to learn how to make stylish shoes that could stand up to a day"s work?

问答题Signs of decline are sure to be found in a place as complex as America: debt, crime, the homeless, drugs, dropouts. But the main characteristic of America, the first and most enduring impression, is dynamism, energy, aggressiveness, forward movement. It is so hard to think of this nation in decline when you know that there are vast regions of the planet which are absolutely paralyzed, incapable of any improvement at all. It is difficult for me to agree with Paul Kennedy's thesis that America must inevitably follow historical precedent. That's the way history used to be—all powerful nations declined and gave way to other empires. But I have a sense that what is going on here concerns much more than the fate of a nation. It may be that the Euro-centered American nation is declining as it gives way to a new Pacific civilization that will include, but not limited to, America. (153 words)
