单选题{{B}}Passage 2{{/B}} My parents' house had an attic, the darkest and strangest part of the building, reach- able only by placing a stepladder beneath the trapdoor, and filled with unidentifiable articles too important to be thrown out with the trash but no longer suitable to have at hand. This mysterious space was the memory of the place. After many years all the things deposited in it became, one by one, lost to consciousness. But they were still there, we knew, safely and comfortably stored in the tissues of the house. These days most of us live in smaller, more modern houses or in apartments, and at- tics have vanished. Even the deep closets in which we used to pile things up for temporary forgetting are rarely designed into new homes. Everything now is out in the open, openly acknowledged and displayed, and whenever we grow tired of a memory, an old chair, a trunkful of old letters, they are cast into the dump for burning. This has seemed a healthier way to live, except maybe for the smoke everything out to be looked at, nothing strange hidden under the roof, nothing forgotten because of no place left in impenetrable darkness to forget. Openness is the new lifestyle, no undisclosed belongings, no private secrets. Candor is the rule in architecture. The house is a machine for living, and what kind of machine would hide away its worn-out, deserted parts? But it is in our nature as human beings to clutter, and we long for places set aside, reserved for storage. We tend to accumulate and outgrow possessions at the same time, and it is an endlessly discomforting mental task to keep sorting out the, ones to get rid of. We might, we think, remember them later and find a use for then, and if they are gone for good, off to the dump, this is a source of nervousness. I think it may be one of the reasons we drum our fingers so much these days. We might take a lesson here from what has been learned about our brains in this century. We thought we discovered, first off, the attic, although its existence has been mentioned from time to time by all the people we used to call great writers. What we really found was the trapdoor and a stepladder, and off we clambered, shining flashlights into the corners, vacuuming the dust out of bureau drawers, puzzling over the names of objects, tossing them down to the floor below, and finally paying around fifty dollars an hour to have them cast away for burning.

单选题As children get older, self-discipline should take the place of imposed discipline. Constrains become internalized and children begin to weigh from within the validity of their promptings(敦促). But their tendency to be self-critical, to develop a code of their own, depends on the extent to which they must have kept critical company. The dialogue within reflects the dialogue without that is why discussion is so important during adolescence. Those in authority over children will, therefore, attempt to get children to do what is sensible by appealing to their common sense instead of ordering them around or appealing to their own status. They will not say, "I'm your father and I'm telling you not to smoke," but will point out the dangers involved. It is a further question, however, whether a child's acceptance of good reasons should be the criterion for his action. If a parent explains to a child why it is stupid and wrong to put objects on railway lines, and yet sees him doing so, will he stand aside and reflect that the boy is learning to choose? Parents must weigh their own fundamental principles against what is instructive for their children. Example, of course, is crucial. Parents and others must provide a pattern out of which the child can eventually develop his own style of self-regulation. This is not likely to happen unless exercise of authority is rationalized and sensitively adapted to age, to persons , and to the tasks in hand. For the young will tightly rebel against the irrational expression of a traditional status. In brief, teachers and parents must learn to be in authority without being authoritarian.

单选题In the massive Zambezi River system, fish are not only vital to the ecosystem, but also a staple in the diet of millions of people. Yet, little is known about the species, their movements and the stocks. In hopes of ensuring that these fish stocks will continue to be around for many years to come, the African Wildlife Foundation has embarked on extensive research and monitoring efforts in the Zambezi River, its tributaries and related reservoirs. While tracking the fish of the Zambezi River system, AWF learned of a sport-fishing tournament taking place on the river. AWF decided to join the tournament. All the tournament catches were carefully monitored and recorded, providing invaluable data on the health and size of key trophy specimens. For the first time in history, real data is now available on the effect of the human population on the Zambezi River network, on the use of incompatible fishing methods, incompatible land uses (like deforestation, which leads to erosion and massive deposits of silt in the river), and over-fishing. All the research will help AWF and its partners to help guide fishery policy and legislation—and help local communities create fishing strategies that are not just profitable, but truly sustainable. For many years, the fish of the Zambezi River network have been bountiful. In fact, the upper part of the river alone feeds 300,000 people. The sardine catch in Lake Kariba yields more than 30,000 tons of fish annually—amounting to more than $55 million a year. To manage the region's fisheries effectively, to monitor water quality, and to keep track of fish yields and fishing activities, AWF created the Aquatic Resources Working Group (ARWG). Its first priority was to gain a greater understanding of the fish that swim in the Zambezi River system as well as a clearer picture of the river system itself. Although data collection will continue, the ARWG has already collected a significant amount of data. Now underway are pilot business ventures with fisheries and the creation of a formal fishing association in which registered fishermen drawn from the local community in Mozambique will undergo training in business skills, best-practice fishing, energy-efficient fish processing and marketing. The future is looking bright for both the fish and the communities along the Zambezi River system.

单选题Which of the following statements about the Third Age in paragraph 2 is true?

单选题Cloning shakes us all to our very souls. For humans to consider the cloning of one another forces them all to question the very concepts of right and wrong that make them all human. The cloning of any species, whether they be human or non-human, is wrong. Scientists and ethicists alike have debated the implications of human or non-human cloning extensively since 1997 when scientists at Roslin Institute in Scotland produced Dolly. No direct conclusions have been drawn, but compelling arguments state that cloning of both human and non-human species results in harmful physical and psychological effects on both groups. The possible physical damage that could be done if human cloning became a reality is obvious when one looks at the sheer loss of life that occurred before the birth of Dolly. Less than ten percent of the initial transfers survive to be healthy creatures. There were 277 trial implants of nuclei. Nineteen of those 277 were deemed healthy while the others were discarded. Five of those nineteen survived, but four of them died within ten days of birth of severe abnormalities. Dolly was the only one to survive. Even lan Wilmut, one of the scientists accredited with the cloning phenomenon at the Roslin Institute agrees, "the more you interfere with reproduction, the more danger there is of things going wrong." The psychological effects of cloning are less obvious, but nonetheless, very plausible. In addition to physical harms, there are worries about the psychological harms to cloned human children. One of those harms is that cloning creates serious issues of identity and individuality. Human cloning is obviously damaging to both the family and the cloned child. It is harder to convince that non-human cloning is wrong and unethical, but it is just the same. Western culture and tradition has long held the belief that the treatment of animals should be guided by different ethical standards than the treatment of humans. Animals have been seen as non-feeling and savage beasts since time began. Humans in general have no problem with seeing animals as objects to be used whenever it becomes necessary. But what would happen if humans started to use animals as body for growing human organs? What if we were to learn how to clone functioning brains and have them grow inside of chimps? Would non-human primates, such as a chimpanzee, who carried one or more human genes via transgenic technology, be defined as still a chimp, a human, a subhuman, or something else? If defined as human, would we have to give it rights of citizenship? And if humans were to carry non-hum, an transgenic genes, would that alter our definitions and treatment of them? Also, if the technology were to be so that scientists could transfer human genes into animals and vice versa, it could create a worldwide catastrophe that no one would be able to stop.
