Feeling stressed out lately? Has the doctor said he cannot find anything wrong with you? Perhaps he sent you to a hospital, but all the (1) equipment there show that there is nothing wrong.Then consider this, you might be in a (2) of sub-health. Sub-health, also called the third state, is (3) as a borderline slate between health and disease. According to an investigation by the National Health Organization, over 45 per cent of subhealthy people are middle-aged or elderly. The percentage is even higher among people who work in management (4) as well as students around exam-time. This may be due to their heightened (5) to stress.Symptoms include a (6) of energy, depression, slow reactions, insomnia, agitation and (7) memory. Other symptoms include shortness of breath, sweating and aching in the waist and legs.According to some medical experts, the (8) to preventing and recovering from sub-health is to form good living habits. (9) work with rest, exercise regularly, and take part in (10) air activities will all help.As for meals, people are (11)to eat less salt and sugar. They should also eat more fresh vegetables, fruits and fish because they are rich in nutritious (12) , such as vitamins, which are (13) to the body.Nutrition experts point out that it is not good to eat too much at one meal because it may cause (14) changes in the digestive tract. They also say that a (15) diet is very helpful in avoiding sub-health.

The Japanese desire for marriage had been very strong. In the fifth "world youth attitude survey" (1 ) by the Management and Coordination Agency in 1993, over 70 percent of the Japanese (2 ) chose the answers "One should get married" or "It's better to get married." Of the 11 countries surveyed, Japan was (3 ) only by the Philippines in the percentage of those advocating marriage (4 ) opposed to a single life.In recent years, however, there has been a spreading recognition among the Japanese public that something (5 ) is happening in people's attitudes toward marriage.When they began to have adequate food, clothing and shelter after years of postwar shortages and thus became able to (6 ) their attention to other matters, the Japanese for the first time (7 ) a renewed look at the question of marriage. In the 1990s, people began to ask "What on earth is marriage anyway?" and to talk about marriage itself.In Japan, the proportion of men still unmarried in their thirties reached about 20 percent in the national census taken in 1985, and the (8 ) apparently exceeded 30 percent in 1995. The proportion of unmarried women in the 25-29 age bracket has been increasing (9 ) about 5 percent every five years until it is now nearly 50 percent.What are the real reasons women choose not to marry? Early on, two were (10 ) ; women were now better educated and more women were interested in working outside the home. Many women have become (11 ) independent, acquiring enough self-confidence to (12 ) a meaningful life outside of marriage. And (13 ) seems to be a wide gap in the way men and women view marriage. Women generally believe that, (14 ) women's roles in Japan's postwar society have become diversified, men have essentially remained unchanged. (15 ) such circumstances, communication between the sexes is, in fact, far from easy.Besides that, in the postwar Japan, individualism has begun to take (16 ) . The 50 years since the end of the war may be regarded as the process of a (17 ) from the family-centered to the individual-centered way of thinking. In Japan today, society has matured to a point (18 ) it now tolerates a diversity of marriage styles which were unthinkable not very long ago. In the future, such tolerance is almost (19 ) to increase. But a headlong plunge toward unbridled individualism is also dangerous. The ideal (20 ) may be to achieve a complementary fusion of the collectivism of Japan's traditional community and the individualism of the new age.

Despite decades of scientific research, no one yet knows how much damage human activity is doing to the environment. Humans are thought to be responsible for a whole host of environmental problems, ranging from global warming to ozone depiction. What is not in doubt, however, is the devastating effect humans are having on the animal and plant life of the planet.Currently, an estimated 50,000 species become extinct every year. If this carries on, the impact on all living creatures is likely to be profound, says Dr Nick Middleton, a geographer at Oxford University. "All species depend in some way on each other to survive. And the danger is that, if you remove one species from this very complex web of interrelationships, you have very little idea about the knock-on effects on the ecosystem. So, if you lose a key species, you might cause a whole cascade of other extinctions."Complicating matters is the fact that there are no obvious solutions to the problem. Unlike global warming and ozone depletion ― which, if the political will was there, could be reduced by cutting gas emissions preserving biodiversity remains an intractable problem.The latest idea is "sustainable management", which is seen as a practical and economical way of protecting species from extinction. This means humans should be able to use any species of animal or plant for their benefit, provided enough individuals of that species are left alive to ensure its continued existence.For instance, instead of depending on largely ineffective laws against poaching, it gives local people a good economic reason to preserve plants and animals. In Zimbabwe, there is a sustainable management project to protect elephants. Foreign tourists pay large sums of money to kill these animals for sport. This money is then given to the inhabitants of the area where the hunting takes place. In theory, locals will be encouraged to protect elephants, instead of poaching them ― or allowing other; to poach them - because of the economic benefit involved.This sounds like a sensible strategy, but it remains to be seen whether it will work. With corruption endemic in many developing countries, some observers are skeptical that the money will actually reach the people it is intended for. Others wonder how effective the locals will be at stopping poachers.There are also questions about whether sustainable management is practical when it comes to protecting areas of great- bio-diversity such as the world's tropical forests. In theory, the principle should be the same as with elephants ― allow logging companies to cut down a certain number of trees, but not so many as to completely destroy the forest.Sustainable management of forests requires controls on the number of trees which are cut down, as well as investment in replacing them. But because almost all tropical forests are located in countries which desperately need revenue from logging, there arc few regulations to do this. Moreover, unrestricted logging is so much more profitable that wood prices from managed forests would cost up to five times more ― an increase that consumers, no matter how "green", are unlikely to pay.For these reasons, sustainable management of tropical forests is unlikely to become widespread in the near future. This is disheartening news. It's estimated these forests contain anything from 50 to 90 percent of all animal and plant species on Earth. In one study of a five-square-kilometer area of rain forest in Peru, for instance, scientists counted 1,300 species of butterfly and 600 species of birD.In the entire continental United States, only 400 species of butterfly and 700 species of bird have been recorded.Scientist Professor Norman Myers sees this situation as a gigantic "experiment we're conducting with our planet". "We don't know what the outcome will be. If we make a mess of it, we can't move to another planet." It's a case of one planet, one experiment."1.What damage do we know for sure is human activity doing to the environment?2.What is an effective way to preserve biodiversity?3.What is NOT true about the idea of sustainable management?4.What factor(s) might affect the practicality of sustainable management?5.Why is sustainable management of tropical forests unlikely to be used in the near future?

To live in the United Slates today is to gain an appreciation for Dahrendorf's assertion that social change exists everywhere. Technology, the application of knowledge for practical ends, is a major source of social change.Yet we would do well to remind ourselves that technology is a human creation; it does not exist naturally. A spear or a robot is as much a cultural as a physical object. Until humans use a spear to hunt game or a robot to produce machine parts, neither is much more than a solid mass of matter. For a bird looking for an object on which to rest, a spear or robot serves the purpose equally well. The explosion of the Challenger space shuttle and the Russian nuclear accident at Chernobyl make people see how important the human quality of technology is; they provide cases in which well-planned systems suddenly became completely disordered and there was no ready hand to set them right. Since technology is a human creation, we are responsible for what is done with it. Pessimists worry that we will use our technology eventually to blow our world and ourselves to pieces. But they have been saying this for decades, and so far we have managed to survive and even flourish. Whether we will continue to do so in the years ahead remains uncertain. Clearly, the impact of technology on our lives deserves a closer examination.Few technological developments have had a greater impact on our lives than the computer revolution. Scientists and engineers have designed specialized machines that can do the tasks that once only people could do. There are those who assert that the switch to an information-based economy is in the same camp as other great historical milestones, particularly the Industrial Revolution. Yet when we ask why the Industrial Revolution was a revolution, we find that it was not the machines. The primary reason why it was a revolutionary is that it led to great social change. It gave rise to mass production and, through mass production, to a society in which wealth was not confined to the few.In somewhat similar fashion, computers promise to revolutionize the structure of American life, particularly as they free the human mind and open new possibilities in knowledge and communication. The Industrial Revolution supplemented and replaced the muscles of humans and animals by mechanical methods. The computer extends this development of supplement and replaces some aspects of the mind of human beings by electronic methods. It is the capacity of the computer for solving problems and making decisions that represents its greatest potential and that poses the greatest difficulties in predicting the impact on society.1.A spear or a robot has the quality of technology only when it ( ) .2.The examples of the Challenger and Chernobyl cited by the author serve to show that( ) .3.According to the author, the introduction of the computer is a revolution mainly because ( ) .4.By using the phrase "the human quality of technology" (line 7, ParA.2), the author refers to the fact that technology ( ).5.The passage is based on the author's( ) .

When people arc struck by lightening, they fall to the ground as though they were struck by a severe blow to the heaD.After the shock they may remain unconscious, become semiconscious or be conscious but confused and dazed, at least for a time. Flashes of light may continue passing before their eyes, and blindness and deafness may follow. The nervous system may be badly affected, causing paralysis, pain in the limbs and even hemorrhage. There will be bums where the lightening passed through the body, and like all electrical bums, they are often deep and severe.All persons, especially campers and hunters, should know how to give first aid to someone who has been struck by lightening. Do not be afraid to touch the victim. You won't get a shock. The lightening has already been groundeD.Remember that speed is of the greatest importance in severe cases.The first thing to do is to loosen tight clothing about the throat and waist. Then clear the air passages of mucus (黏液)if present, and apply artificial respiration if necessary. Give mouth-mouth resuscitation if needed, or give oxygen if available. Many victims thought Io be dead have been revived after treatment.Send someone for a doctor as soon as possible, but don't leave the victim alone. If a doctor is not available, take the person to a hospital as soon as the person can be safely moved.Signs of shock are: pale, cold, sticky skin; weak, rapid pulse; shallow, irregular breathing or, in extreme cases, no breathing at all. To treat shock, you must keep the patient lying down with the head lower than the feet and cover him or her with a blanket but watch out for overheating. Giving a stimulating hot tea or coffee will help, but only if the patient is thoroughly conscious.After breathing has been restored and shock is treated, treat the bums. Apply some salve and cover them with a clean cloth or a sterile dressing. If conscious, the patient will be badly frightened, so do all you can to reassure. A little knowledge and a helping hand may save someone's life.1.The passage mainly talks about ( ) .2.According lo the passage, all the following are signs of shock except ( ) .3.It can be guessed from the passage that ( ) .4.The word "salve" in line 2 of the last paragraph most likely means ( ) .5.Which of the following must not be done while treating shock?

When a Scottish research team startled the world by revealing three months ago that it had cloned an adult sheep, President Clinton moved swiftly. Declaring that he was opposed to using this unusual animal husbandry technique to clone humans, he ordered that federal funds not be used for such an experiment although no one had proposed to do so — and asked an independent panel of experts chaired by Princeton President Harold Shapiro to report back to the White House in 90 days with recommendations for a national policy on human cloning. That group - the national Bioethics Advisory Commission - has been working feverishly to put its wisdom on paper, and at a meeting on 17 May, members agreed on a near-final draft of the recommendations.NBAC will ask that Clinton's 90-day ban on federal funds for human cloning be extended indefinitely, and possibly that it be made law. But NBAC members are planning to word the recommendation narrowly to avoid new restrictions on research that involves the cloning of human DNA or cells -- routine in molecular biology. The panel has not yet reached agreement on a crucial question, however, whether to recommend legislation that would make it a crime for private funding to be used for human cloning.In a draft preface to the recommendations, discussed at the 17 May meeting, Shapiro suggested that the panel had found a broad consensus that it would be "morally unacceptable to attempt to create a human child by adult nuclear cloning." Shapiro explained during the meeting that the moral doubt stems mainly from fears about the risk to the health of the chilD.The panel then informally accepted several general conclusions, although some details have not been settled.NBAC members also indicated that they will appeal to privately funded researchers and clinics not to try to clone humans by body cell nuclear transfer. But they were divided on whether to go further by calling for a federal law that would impose a complete ban on human cloning. Shapiro and most members favored an appeal for such legislation. But in a phone interview, he said this issue was still "up in the air."1.We can learn from the first paragraph that( ) .2.The meaning of the word "consensus" in Paragraph 3 is closest to ( ) .3.The panel agreed on all of the following except that ( ) .4.Which of the following statements can be inferred from Paragraph 2?5.It can be inferred from the last paragraph that ( ) .

Is language, like food, a basic human need without which a child at a critical period of life can be starved and damaged? Judging from the drastic experiment of Frederick II in the thirteenth century, it may be. Hoping to discover what language a child would speak if he heard no mother tongue, he told the nurses to keep silent.All the infants died before the first year. But clearly there was more than lack of language here. What was missing was good mothering. Without good mothering, in the first year of life especially, the capacity to survive is seriously affected.Today no such severe lack exists as that ordered by Frederick. Nevertheless, some children are still backward in speaking. Most often the reason for this is that the mother is insensitive to the signals of the infant, whose brain is programmed to learn language rapidly. If these sensitive periods are neglected, the ideal time for acquiring skills passes and the language might never be learned so easily again. A bird learns to sing and to fly rapidly at the right time, but the process is slow and hard once the critical stage has passed.Experts suggest that speech stages are reached in a fixed sequence and at a constant age, but there are cases where speech has started late in a child who eventually turns out to be a high IQ. At twelve weeks a baby smiles and makes vowel-like sounds, at twelve months he can speak simple words and understand simple commands, at eighteen months he has a vocabulary of three to fifty words. At three he knows about 1000 words which he can put into sentences, and at four he knows his language differs from that of his parents in style rather than grammar.Recent evidence suggests that an infant is born with the capacity of speaking. What is special about man's brain, compared with that of the monkey, is the complex system which enables a child to connect the sight and feel of, say, a toy-bear with the sound pattern "toy-bear". And even more incredible is the young brain's ability to pick out an order in language from the mixture of sound around him, to analyze, to combine and recombine the parts of a language in new ways.But speech has to be induced, and this depends on interaction between the mother and the child, where the mother recognizes the signals in the child's babbling, grasping and smiling, and responds to them. Insensitivity of the mother to these signals dull the interaction because the child gets discouraged and sends out only the obvious signals. Sensitivity to the child's non-verbal signals is essential to the growth and development of language. 1.What is the purpose of the drastic experiment of Frederick II in the thirteenth century?2.Today some children are backward in speaking because ( ) .3.If a child starts to speak later than other normal children, he will ( ) in the future.4.Compared with the brain of the monkey, human's brain is a complex system which enables a child ( ) .5.Which of the following can NOT be inferred from the passage?

Developing a peaceful, understanding, and supportive relationship between parents and children is not an easy task. Failures can and do occur at any age level, and at times the results arc the abuse, neglect, and even death of children.Child abuse has become a major topic in child development and an issue of much national concern. In the span of four legislative years, 1963 - 1967, all fifty states enacted laws calling for the reporting of injuries inflicted on children. By 1973, the United States Congress passed the Child Abuse Prevention and Treatment Act (Public Law 93 - 247). This law not only reflected the mood of concerned citizens, but it also did much to clear up the confusion and disagreement over what is child abuse.The question "what causes child abuse?" has prompted much debate. The single most persistent myth which had plagued efforts to understand causes is the notion that parents who abuse children are mentally disturbed or ilk Although there is no specific psychiatric diagnosis which comprises the behavior and personalities of abuser, they seem to share a common style of child rearing. Those parents demand high levels of child performance and they often use severe physical punishment to ensure the child's proper behavior. Abusive parents themselves were raised in similar family situations and their own childhood experience has a lasting influence on their behavior as adults.Current research has suggested, however, that the "abuser is sick" hypothesis is too limiteD.A broader social, psychological approach recognizes that some personal problems are implicit but that psychological factors arise out of a social context. Social factors include unemployment, social isolation, and unwanted pregnancy. Moreover, findings that abuse occurs more frequently in larger families and families with low income, poor education, and low occupational status suggest that many such parents cannot withstand the twenty-four-hour-a-day responsibility to raise and care for their children. These problems aggravate the situation, especially when combined with the general approval in our culture of violence.1.This selection suggests that child abuse is( ) .2.We can know from the second paragraph that the law passed by 1973( ) .3.The person who is least likely to be a child-abusing parent is the one who( ).4.Which one of the following is most probably a cause of child abuse?5.Which of the following statements is the author most likely to agree with?
