But it works because the energy from the blow gets distributed throughout the wood rather than focusing on one weak spot. The discovery should lead to more effective and lighter packaging materials. Carpenters have known{{U}} (51) {{/U}}centuries that some woods are tougher than others. Hickory (山核桃木), for example, was turned into axe handles and cartwheel spokes (轮辐) because it can absorb shocks without breaking. White oak, for example, is much more easily damaged,{{U}} (52) {{/U}}it is almost as dense. Julian Vincent at Bathe University and his team were convinced the wood's internal structure could explain the differences. Many trees have tubular (管的) vessels that run{{U}} (53) {{/U}}the trunk and carry water to the leaves. In oak they are large, and arranged in narrow bands, but in hickory they are smaller, and more evenly distributed. The researchers{{U}} (54) {{/U}}this layout might distribute a blow's energy throughout the wood, soaking up a bigger hit. To test the idea, they drilled holes 0.65 millimetres across into a block of spruce (云杉), a wood with{{U}} (55) {{/U}}vessels, and found that{{U}} (56) {{/U}}withstood a harder knock.{{U}} (57) {{/U}}when there were more than about 30 holes per square centimetre did the wood's performance drop off. A uniform substance doesn't cope well with knocks because only a small proportion of the material is actually{{U}} (58) {{/U}}. All the energy from the blow goes towards breaking the material in one or two places, but often the pieces left{{U}} (59) {{/U}}are pristine (未经破坏的). But instead of the energy being concentrated in one place, the holes provide many weak spots that all absorb energy as they break, says Vincent. "You are controlling the places{{U}} (60) {{/U}}the wood breaks, and it can then absorb more{{U}} (61) {{/U}}, more safely." The researchers believe the principle could be applied to any material—{{U}} (62) {{/U}}example, to manufacture lighter and more protective packaging. It could{{U}} (63) {{/U}}be used in car bumpers, crash barriers and armour for military vehicles, says Ulrike Wegst,{{U}} (64) {{/U}}the Max Plank Institute for Mental Research in Stuttgart. But she emphasizes that you{{U}} (65) {{/U}}to design the substance with the direction of force in mind. "The direction of loading is crucial," she says.

单选题Fighting for a Brighter Future for Women When I was asked what it means to be a woman running for president, I always gave the same answer that I was proud to be running as a woman, but I was running because I thought I'd be the best president. But I am a woman and, like millions of women, I know there are still barriers and biases (偏见) out there, often unconscious, and I want to build an America that respects and embraces the potential of every last one of us. I ran as a daughter who benefited from opportunities my mother never dreamed of. I ran as a mother who worried about my daughter's future and a mother who wants to leave all children brighter tomorrows. To build that future I see, we must make sure that women and men alike understand the struggles of their grandmothers and their mothers, and that women enjoy equal opportunities, equal pay, and equal respect. Let us resolve and work toward achieving very simple propositions (命题) :There are no acceptable limits, and there are no acceptable prejudices in the 21st century in our country. You can also be so proud that, from now on, it will be unremarkable for a woman to win primary state victories, unremarkable to have a woman in a close race to be our nominee (被提名者), unremarkable to think that a woman can be the president of the United States. And this is truly remarkable, my friends. To those who are disappointed that we couldn't go all of the way, especially the young people who put so much into this campaign, it would break my heart if, in falling short of my goal, I in any way discouraged any of you from pursuing yours. Always aim high, work hard, and care deeply about what you believe in. And, when you stumble (绊倒) ,keep faith. And, when you're knocked down, get right back up and never listen to anyone who says you can't or shouldn't go on. As we gather here today in this historic, magnificent building, the 50th woman to leave the Earth is orbiting (绕轨道运行) overhead. If we can blast 50 women into space, we will someday launch a woman into the White House.

These reminiscences (回忆) are not simply random or trivial memories,{{U}} (51) {{/U}}is their purpose merely to make conversation. The old person's recollections of the past help to{{U}} (52) {{/U}}an identity that is becoming increasingly fragile (脆弱的):{{U}} (53) {{/U}}any role that brings respect or any goal that might provide orientation to the future, the individual mentions their past as a reminder to listeners, that here was a life{{U}} (54) {{/U}}living.{{U}} (55) {{/U}}, the memories form part of a continuing life{{U}} (56) {{/U}}, in which the old person{{U}} (57) {{/U}}the events and experiences of the years gone by and reflects on the overall meaning of his or her own almost completed life. As the life cycle{{U}} (58) {{/U}}to its close, the aged must also learn to accept the reality of their own impending (即将发生的) death.{{U}} (59) {{/U}}this task is made difficult by the fact that death is almost a{{U}} (60) {{/U}}subject in the United States. The mere discussion of death is often regarded as{{U}} (61) {{/U}}As adults many of us find the topic frightening and are reluctant to think about it and certainly not to talk about it{{U}} (62) {{/U}}the presence of someone who is dying. Death has achieved this taboo{{U}} (63) {{/U}}only in the modern industrial societies. There seems to be an important reason for our reluctance to{{U}} (64) {{/U}}the idea of death. It is the very fact that death remains{{U}} (65) {{/U}}our control; it is almost the only one of the natural processes that is so.

单选题The Worker"s Role in Management Traditionally, it has been the worker"s role to work and management"s role to manage. Managers have planned and directed the firm"s operation with little thought of consulting the labor force. Managers have rarely felt compelled (被迫的) to obtain the worker"s opinions or to explain their decisions to their employees. At most, companies have provided "suggestion boxes" in which workers could place ideas for improving procedures. In recent years, however, many management specialists have been arguing that workers are more than sellers of labor—they have a vital stake in the company and may be able to make significant contributions to its management. Furthermore, major company decisions profoundly affect workers and their dependents. This is particularly true of plant closings, which may put thousands on the unemployment lines. Should workers, then, play a stronger role in management? Workers should have a role in management. At the very least, the labor force should be informed of major policy decisions. (A common complaint among rank-and-file workers is the lack of information about company policies and actions.)Between 1980 and 1985 about five million workers were the victims of plant closings and permanent layoffs, often with no warning. At least 90 day"s notice ought to be given in such instances so that workers have time to adjust. Management should consult workers before closing a plant, because the workers might be able to suggest ways of improving productivity and reducing costs and might be willing to make concessions that will help keep the plant operating. It should become a general practice to include workers in some managerial decision making. There ought to be representatives of the workers on the firm"s board of directors or other major policymaking groups. If rank-and-file workers are given a voice in the planning and management of the work flow, they will help to make improvements, their morale will rise, and their productivity will increase. As a further incentive, they must be given a share in the company"s profits. This can be done through employee stock ownership plans, bonuses, or rewards for efficiency and productivity. Finally, when a plant can no longer operate at a profit, the workers should be given the opportunity to purchase the plant and run it themselves.

单选题Man of Few Words Everyone chases success, but not all of us want to be famous. South African writer John Maxwell Coetzee is (1) for keeping himself to himself. When the 63-year-old was named the 2003 Nobel Prize winner for literature earlier this month, reporters were warned that they would find him " particularly difficult to (2) ". Coetzee lives in Australia but spends part of the year teaching at the University of Chicago. He seemed (3) by the news that he won the U. S. $1.3 million prize. "It came as a complete surprise.

But despite being described as (5) to track down, the critics agree that his writing is easy to get to know. Born in Cape Town, South Africa, to an English-speaking family, Coetzee (6) his breakthrough in 1980 with the novel "Waiting for the Barbarians (野蛮人)". He (7) his place among the world's leading writers with two Booker prize victories, Britain's highest honour for novels. He first (8) in 1983 for the "Life and Times of Michael K", and his second title came in 1999 for "Disgrace". A major theme in his work is South Africa's former apartheid (种族隔离) system, which divided whites from blacks. (9) with the problems of violence, crime and racial division that still exist in the country, his books have enabled ordinary people to understand apartheid (10) within. "I have always been more interested in the past than the future," he said in a rare interview. "The past (11) its shadow over the present. I hope I have made one or two people think (12) about whether they want to forget the past completely. " In fact this purity in his writing seems to be (13) in his personal life. Coetzee is a vegetarian, a cyclist rather than a motorist and doesn't drink alcohol. But what he has (14) to literature, culture and the people of South Africa is far greater than the things he has given up. "In looking at weakness and failure in life," the Nobel prize judging panel said, "Coetzee's work (15) the divine (神圣的) spark in man. /
