Dogs are social animals and without proper training, they will be have like wild animals. They will spoil your house, destroy your belongings, bark excessively, fight other dogs and even bite you. Nearly all behavior problems are perfectly normal dog activities that occur at the wrong time or place or are directed at the wrong thing. The key to preventing or treating behavior problems is learning to teach the dog to redirect its normal behavior to outlets that are acceptable in the domestic setting. one of the best things you can do for your dog and yourself is to obedience train (驯服) it. Obedience training doesn't solve all behavior problems, but it is the foundation for solving just about any problem. Training opens up a line of communication between you and your dog. Effective communication is necessary to instruct your dog about what you want it to do. Training is also an easy way to establish the social rank order. When your dog obeys a simple request of "come here, sit," it is showing obedience and respect for you. It is not necessary to establish yourself as top dog or leader of the dog pack (群) by using extreme measures. You can teach your dog its subordinate (从属的) role by teaching it to show submission to you. Most dogs love performing tricks for you to pleasantly accept that you are in charge. Training should be fun and rewarding for you and your dog. It can enrich your relationship and make living together more enjoyable. A well-trained dog is more confident and can more safely be allowed a grea- ter amount of freedom than an untrained animal.

单选题The mid-sixties saw the start of a project that, along with other similar research, was to teach us a great deal about the chimpanzee mind. This was project Washoe, conceived by Trixie and Allen Gardner. They purchased an infant chimpanzee and began to teach her the signs of ASL, the American Sign Language used by the deaf. Twenty years earlier another husband and wife team, Richard and Cathy Hayes, had tried, with an almost total lack of success, to teach a young chimp, Vikki, to talk. The Hayes's undertaking taught us a test about the chimpanzee mind, but Vikki, although she did well in IQ tests, and was clearly an intelligent youngster, could not learn human speech. The Gardners, however, achieved spectacular success with their pupil, Washoe. Not only did she learn signs easily, but she quickly began to string them together in meaningful ways. It was clear that each sign evoked, in her mind, a mental image of the object it represented. If, for example, she was asked, in sign language, to fetch an apple, she would go and locate an apple that was out of sight in another room. Other chimps entered the project, some starting their lives in deaf signing families before joining Washoe. And finally Washoe adopted an infant, Loulis. He came from a lab where no thought of teaching signs had ever penetrated. When he was with Washoe he was given no lessons in language acquisition--not by humans, anyway. Yet by the time" he was eight years old. he had made fifty-eight signs in their correct contexts. How did he learn them? Mostly, it seems, by imitating the behavior of Washoe and the other three signing chimps, Dar, Moja and Tam. Sometimes, though, he received tuition from Washoe herself. One day, for example, she began to swagger about bipedally, hair bristling, signing food! food! food! in great excitement. She had seen a human approaching with a bar of chocolate. Loulis, only eighteen months old, watched passively. Suddenly Washoe stopped her swaggering, went over to him, took his hand, and moulded the sign for food (fingers pointing towards mouth). Another time, in a similar context, she made the sign for chewing gum, but with her hand on his body. On a third occasion Washoe picked up a small chair, took it over to Loulis, set it down in front of him, and very distinctly made the chair sign three times, watching him closely as she did so. The two food signs became incorporated into Loulis's vocabulary but the sign for chair did not. Obviously the priorities of a young chimp are similar to those of a human child! Chimpanzees who have been taught a language can combine signs creatively in order to describe objects for which they have no symbol. Washoe, for example, puzzled her caretakers by asking, repeatedly, for a rock berry. Eventually it transpired that she was referring to brazil nuts which she had encountered for the first time a while before. Another language- trained chimp described a cucumber as a green banana. They can even invent signs. Lucy, as she got older, had to be put on a leash for her outings. One day, eager to set off but having no sign for leash, she signaled her wishes by holding a crooked index finger to the ring on her collar. This sign became part of her vocabulary.

单选题From the health point of view we are living in a marvelous age. We are immunized from birth against many of the most dangerous diseases. A large number of once fatal illnesses can now be cured by modern drugs and surgery. It is almost certain that one day remedies will be found for the most stubborn remaining diseases. The expectation of life has increased enormously. But though the possibility of living a long and happy life is greater than ever before, every day we witness the incredible slaughter of them, women and children on the roads. Man versus the motor-car! It is a never-ending battle which man is losing. Thousand of people the world over are killed or horribly killed each year and we are quietly sitting back and letting it happen. It has been rightly ;aid that when a man is sitting behind a steering wheel, his car becomes the extension of his personality. There is no doubt that the motor-car often brings out a man's very worst qualities. People who are normally quiet and pleasant may become unrecognizable when they are behind steering, wheels. They swear, they are ill-mannered and aggressive, willful as two-year-olds and utterly selfish. All their bidden frustrations, disappointments and jealousies seem to be brought to the surface by the act of driving. The surprising thing is that the society smiles so gently on the motorist and seems to forgive his behavior. Everything is done for his convenience. Cities are allowed to become almost uninhabitable because of heavy traffic; towns are made ugly by huge car parks; the countryside is desecrated by road networks; and the mass annual slaughter becomes nothing more than a statistic, to be conveniently forgotten. It is high time a world code were created to reduce this senseless waste of human life. With regard to driving, the laws of some countries are notoriously lax and even the strictest are not strict enough. A code which was universally accepted could only have a dramatically beneficial effect on the accident rate. Here are a few examples of some of the things that might be done. The driving test should be standardized and made far more difficult than it is; all the drivers should be made to take a test every three years or sol the age at which young people are allowed to drive any vehicle should be raised to at least 21; all vehicles should be put through strict annual tests for safety. Even the smallest amount of alcohol in the blood can impair a person's driving ability. Present drinking and driving laws (where they exist) should be made much stricter. Maximum and minimum speed limits should be imposed on all roads. Governments should lay down safety specifications for manufacturers, as has been done in the USA. All advertising stressing power and performance should be banned. These measures may sound inordinately harsh. But surely nothing should be considered as too severe if it results in reducing the annual toll of human life. After all, the world is for human beings, not for motor-cars.

单选题Being a man has always been dangerous. There are about 105 males born for every 100 females, but this ratio drops to near balance at the age of maturity, and among 70-year-olds there are twice as many women as men. But the great universal of male mortality is being changed now, by babies survive almost as well as girls do. This means that, for the first time, there will be an excess of boys in those crucial years when they are searching for a mate. More important, another chance for natural selection has been removed. Fifty years ago, the chance of a baby (particularly a boy baby) surviving depended on its weight. A kilogram too light or too heavy meant almost certain death. Today it makes almost no difference. Since much of the variation is due to genes one more agent of evolution has gone. There is another way to commit evolutionary suicide: stay alive, but have fewer children. Few people are as fertile as in the past. Except in some religious communities, very few women has 15 children. Nowadays, the number of births, like the age of death, has become average. Most of us have roughly the same number of offspring. Again, differences between people and the opportunity for natural selection to take advantage of it have diminished India shows what is happening. The country offers wealth for a few in the great cities and poverty for the remaining tribal peoples. The grand mediocrity of today everyone being the same in survival and number of offspring means that natural selection has lost 80% of its power in upper-middle-class India compared to the tribes. For us, this means that evolution is over; the biological Utopia has arrived. Strangely, it has involved little physical change. No other species fills so many places in nature. But in the pass 100,000 years—even the pass 100 year our lives have been transformed but our bodies have not. We did not evolve, because machines and society did it for us. Darwin had a phrase to describe those ignorant of evolution: they "look at an organic being as average looks at a ship, as at something wholly beyond his comprehension." No doubt we will remember a 20th century way of life beyond comprehension for its ugliness. But however amazed our descendants may be at how far from Utopia we were, they will look just like us.

单选题When we think about addiction to drugs or alcohol, we frequently focus on negative aspects, ignoring the pleasures that accompany drinking or drug-taking. (21) the essence of any serious addiction is a pursuit of pleasure, a search for a "high" that normal life does not (22) . It is only the inability to function (23) the addictive substance that is dismaying, the dependence of the organism upon a certain experience and a(n) (24) inability to function normally without it. Thus a person will take two or three (25) at the end of the day not merely for the pleasure drinking provides, but also because he "doesn't feel (26) " without them.

Other potentially pleasurable experiences axe no longer possible, (30) under the spell of the addictive experience, his life is peculiarly (31) . The addict craves an experience and yet he is never really satisfied. The organism may be (32) sated, but soon it begins to crave again. Finally a serious addiction is (33) a harmless pursuit of pleasure by its distinctly destructive elements. A heroin addict, for instance, leads a (34) life: his increasing need for heroin in increasing doses prevents him from Working, from maintaining relationships, from developing in human ways.

单选题 The most effective attacks against globalization are usually not those related to economics. Instead, they are social, ethical and, above all, cultural. These arguments surfaced amid the disturbance of Seattle in 1999 and have resonated (产生反响) more recently in Davos, Bangkok and Prague. They say this. The disappearance of national borders and the establishment of a world interconnected by markets will deal a death blow to regional and national cultures, and to the traditions, customs, myths and mores that determine each country's or region's cultural identity. Since most of the world is incapable of resisting the invasion of cultural products from developed countries--or, more to the point, from the superpower, the United States--that inevitably trails the great transnational corporations, North American culture will ultimately impose itself, standardizing the world and annihilating its rich flora of diverse cultures. In this manner, all other peoples, and not just the small and weak ones, will lose their identity, their soul, and will become no more than 21st century colonies modeled after the cultural norms of a new imperialism that, in addition to ruling over the plant with its capital, military strength and scientific knowledge, will impose on others its language and its ways of thinking, believing, enjoying and dreaming. Even though I believe this cultural argument against globalization is unacceptable, we should recognize that deep within it lies an unquestionable truth. This century, the world in which we will live will be less picturesque and filled with less local color than the one we left behind. The festivals, clothing, customs, ceremonies, rites and beliefs that in the past gave humanity its folkloric and ethnological (民族的) variety are progressively disappearing or confining themselves to minority sectors, while the bulk of society abandons them and adopts others more suited to the reality of our time. All countries of the earth experience this process, some more quickly than others, but it is not due to globalization. Rather, it is due to modernization, of which the former is effect, not cause. It is possible to feel deep sorrow, certainly, that this process occurs, and to feel nostalgia (怀旧) for the past ways of life that, particularly from our comfortable position of the present, seem full of amusement, originality and color. But this process is unavoidable. In theory, perhaps, a country could keep this identity, but only if like certain remote tribes in Africa or the Amazon--it decides to live in total isolation, cutting off change with other nations and practicing self-sufficiency, a cultural identity preserved in this form would take that society back to prehistoric standards of living. It is true that modernization makes many forms of traditional life disappear. But at the same time, it opens opportunities and constitutes an important step forward for a society as a whole. This is why, when given the option to choose freely, peoples, sometimes counter to what their leaders or intellectual traditionalists would like, choose for modernization without the slightest ambiguity.
