问答题难道再也没有时间阅读书籍吗?现在你可以利用电子邮件从书籍里面解放出来。通过两年前创建的在线图书俱乐部——“一日一章”，有10万多的人们可以通过打开邮件阅读一本书中的一章。这种免费的邮件服务可给忙碌人士提供每日短暂的阅读，提供他们自己可能找不到的一些文学作品，同时让他们形成阅读的好习惯。大约550个公共图书馆系统所包含的超过3000个分支图书馆已经签约提供“一日一章”电子邮件，参与每日五分钟阅读价值这种活动。当邮件提供到三章后就停止为读者电邮分期连载的文学作品，但那些想继续坚持阅读的人可以通过公共图书馆阅读或者在线搜寻。“一日一章”拥有八个免费的图书俱乐部，销售大约上千本图书。 “一日一章”是由一位终身的图书爱好者——苏珊娜·比彻创立于1999年。当时，她意识到那些在软件开发公司做兼职的女士一生忙碌却没有时间阅读。她决定打出一本书中的一章，通过电子邮件发给她的员工。第二天她又打多了一点，继续每天都发送一些文章。她说她开始得到员工每天阅读的感受，“那些书太有意思了，同时意识到，虽然在她们忙碌的一生里几乎没有时间阅读，但是每日一点的阅读就使她们形成了习惯”。她意识到其他的人同样可以从中受益，所以她决定开发这种思想，同时创立“一日一章”图书俱乐部，以帮助其他人恢复每日阅读的习惯。比彻说：“阅读改变了人们的生活。” 一位在俄亥俄公共图书管的图书商——帕特·戴姆森已经建立了“一日一读”帮助她的员工恢复阅读的习惯。她说：“这是一种让人们热衷于读书的特殊方法”。

问答题What"s your earliest childhood memory? Can you remember learning to walk? Or talk? The first time you heard thunder or watched a television program? Adults seldom recall events much earlier than the year or so before entering school, just as children younger than three or four rarely retain any specific, personal experiences. A variety of explanations have been proposed by psychologists for this "childhood amnesia"(儿童失忆症). One argues that the hippocampus, the region of the brain which is responsible for forming memories, does not mature until about the age of two. But the most popular theory maintains that, since adults do not think like children, they cannot reflect childhood memories. Adults think in words, and their life memories are like stories or narratives—one event follows another as in a novel or film. But when they search through their mental files for early childhood memories to add to this verbal life story, they don"t find any that fits the pattern It"s like trying to find a Chinese word in an English dictionary. Now psychologist Annette Simms of the New York State University offers a new explanation for childhood amnesia. She argues that there simply aren"t any early childhood memories to recall. According to Dr. Simms, children need to learn to use someone else"s spoken description of their personal experiences in order to turn their own short-term, quickly forgotten impressions of them into long-term memories. In other words, children have to talk about their experiences and hear others talk about theirs—Mother talking about the afternoon spent looking for seashells at the beach or Dad asking them about their day at Ocean park. Without this verbal reinforcement, says Dr. Simms, children cannot form permanent memories of their personal experiences.

问答题For all the fevered work being done, however, science is still far away from the Brave New World vision of engineering a perfect human or even a perfect tomato. Much more research is needed before gone therapy becomes commonplace, and many diseases will take decades to conquer, if they can be conquered at all. In the short run, the most practical way to use the new technology will be in genetic screening. Doctors will be able to detect all sorts of flaws in DNA long before they can be fixed. In some cases the knowledge may lead to treatments that delay the onset of the disease or soften its effects. Someone with a genetic predisposition to heart disease, for example, could follow a low-fat diet. And if scientists determine that a vital protein is missing because the gone that was supposed to make it is defective, they might be able to give the patient an artificial version of the protein. But in other instances, almost nothing can be done to stop the ravages brought on by genetic mutations.

问答题In man"s early days, competition with other creatures must have been critical. But this phase of our development is now finished. Indeed, we lack practice and experience nowadays in dealing with primitive conditions. 11 I am sure that, without modern weapons, I would make a very poor show of disputing the ownership of a cave with a bear, and in this I do not think that I stand alone. The last creature to compete with man was the mosquito. But even the mosquito has been subdued by attention to drainage and by chemical sprays. 12 Competition between ourselves, person against person, community against community, still persists, however; and it is as fierce as it ever was. But the competition of man against man is not the simple process envisioned in biology. 13 It is not a simple competition for a fixed amount of food determined by the physical environment, because the environment that determines our evolution is no longer essentially physical. Our environment is chiefly conditioned by the things we believe. Morocco and California are bits of the Earth in very similar latitudes, both on the west coasts of continents with similar climates, and probably with rather similar natural resources. 14 Yet their present development is wholly different, not so much because of different people even, but because of the different thoughts that exist in the minds of their inhabitants. This is the point I wish to emphasize. The most important factor in our environment is the state of our own minds. 15 It is well known that where the white man has invaded a primitive culture the most destructive effects have come not from physical weapons but from ideas. Ideas are dangerous. The Holy Office knew this full well when it caused heretics to be burned in days gone by. Indeed, the concept of free speech only exists in our modem society because when you are inside a community you are conditioned by the conventions of the community to such a degree that it is very difficult to conceive of anything really destructive.

问答题People all over the world today are beginning to hear and learn more and more about, the problem of pollution. 21 Pollution is caused either by the released by man of completely new and often artificial substances into the environment, or by releasing greatly increased amounts of a natural substance, such as oil from tankers into the sea. 22 The whole industrial process which makes many of the goods and machines we need and use in our daily lives, is bound to create a number of waste products to upset the environment balance, or the ecological balance as it is also known. Many of these waste products can be prevented or disposed of sensibly, but clearly while more and more new goods are produced and made complex, there will be new, dangerous wastes to be disposed of, for example, the waste products from nuclear power stations. Many people, therefore, see pollution as only part of a larger and more complex problem, that is, the whole process of industrial production and consumption of goods. 23 Others again see the problem mainly in connection with agriculture, where new methods are helping farmers grow more and more on their land to feed our ever-increasing populations. However, the land itself is gradually becoming worn out as it is being used, in some cases, too heavily, and artificial fertilizers cannot restore the balance. 24 Whatever its underlying reasons, there is no doubt that much of the pollution cause could be controlled if only companies, individuals and governments would make more efforts. In the home there is an obvious need to control litter and waste. Food comes wrapped up three or four times in packages that all have to be disposed of; drinks are increasingly sold in bottles or tins which cannot be reused. This not only causes a litter problem, but also is a great waste of resources, in terms of glass, metals and paper. 25 Advertising has helped this process by persuading many of us not only to buy things we neither want nor need, but also throw away much of what we do buy. Pollution and waste combine to be problem everyone call help to solve by cutting out unnecessary buying, excess consumption and careless disposal of the products we use in our daily lives.
