单选题"In every known human society the male's needs for achievement can be recognized. . . In a great number of human societies men's sureness of their sex role is tied up with their right, or ability, to practice some activity that women are not allowed to practice. Their maleness in fact has to be underwritten by preventing women from entering some field or performing some feat. " This is the conclusion of the anthropologist Margaret Mead about the way in which the roles of men and women in society should be distinguished. If talk and print are considered it would seem that the formal emancipation of women is far from complete. There is a flow of publications about the continuing domestic bondage of women and about the complicated system of defences which men have thrown up around their hitherto accepted advantages, taking sometimes the obvious form of exclusion from types of occupation and sociable groupings, and sometimes the more subtle form of automatic doubt of the seriousness of women's pretensions to the level of intellect and resolution that men, it is supposed, bring to the business of running the world. There are a good many objective pieces of evidence for the erosion of men's status. In the first place, there is the widespread postwar phenomenon of the woman Prime Minister, in India, Sri Lanka and Israel. Secondly, there is the very large increase in the number of women who work, especially married women and mothers of children. More diffusely there are the increasingly numerous convergences between male and female behaviour: the approximation to identical styles in dress and coiffure, the sharing of domestic tasks, and the admission of women to all sorts of hitherto exclusively male leisure-time activities. Everyone carries round with him a fairly definite idea of the primitive or natural conditions of human life. It is acquired more by the study of humorous cartoons than of archaelology, but that does not matter since it is not significant as theory but only as an expression of inwardly felt expectations of people's sense of what is fundamentally proper in the differentiation between the roles of the two sexes. In this rudimentary natural society men go out to hunt and fish and to fight off the tribe next door while women keep the fire going. Amorous initiative is firmly reserved to the man, who sets about courtship with a club.

单选题 The current emergency in Mexico City that has taken over our lives is nothing. I could ever have imagined for me or my children. We are living in an environmental crisis, an air-pollution emergency of unprecedented severity. What it really means is that just to breathe here is to play a dangerous game with your health. As patents, what terrorizes us most are reports that children are at higher risk because they breathe more times per minute. What more can we do to protect them and ourselves? Our pediatrician's (儿科医师的) medical recommendation was simple: abandon the city permanently. We are foreigners and we are among the small minority that can afford to leave. We arc here because of my husband's work. We are fascinated by Mexico--its history and rich culture. We know that for us, this is a temporary danger. However, we cannot stand for much longer the fear we feel for our boys. We cannot stop them from breathing. But for millions, there is no choice. Their lives, their jobs, their futures depend on being here. Thousands of Mexicans arrive each day in this city, desperate for economic opportunities. Thousands more are born here each day. Entire families work in the streets and practically live there. It is a familiar sight: as parents hawk goods at stoplights, their children play in the grassy highway dividers, breathing exhaust fumes. I feel guilty complaining about my personal situation; we won't be here long enough for our children to form the impression that skies are colored only gray. And yet the government cannot do what it must to end this problem. For any country, especially a developing Third World economy like Mexico, the idea of barring from the capital city enough cars, closing enough factories and spending the necessary billions on public transportation is simply not an option. So when things get bad, as in the current emergency, Mexico takes half measures--prohibiting some more cars from circulating, stopping some factories from producing--that even its own officials concede aren't adequate. The word "emergency" implies the unusual. But when daily life itself is an emergency, the concept loses its meaning. It is human nature to try to adapt to that which we cannot change or to mislead ourselves into believing we can adapt.

单选题{{B}}Passage Three{{/B}} When I was a child in Sunday school, I would ask searching questions like "Angels can fly up in heaven, but how do clouds hold up pianos, and get the same puzzling response about how that was not important, what was important was that Jesus died for our sins and if we accepted him as our savior, when we died, we would go to heaven, where we'd get everything we wanted. Some children in my class wondered why anyone would hang on a cross with nails stuck through his hands to help anyone else; I wondered how Santa Claus knew what I wanted for Christmas, even though I never wrote him a letter. Maybe he had a tape recorder hidden in every chimney in the world. This literal-mindedness has stuck with me; one result of it is that I am unable to believe in God. Most of the other atheists I know seem to feel freed or proud of their unbelief, as if they have cleverly refused to be sold snake oil. My husband, who was reared in a devout Catholic family, has served as an altar boy. So other than baptizing our son to reassure our families, we've skated over the issue of faith. Some people believe faith is a gift; it's a choice, a matter of spiritual discipline. I have a friend who was reared to believe, and he does. But his faith has wavered. He has struggled to hang onto it and to pass it along to his children. Another friend of mine never goes to church because she's a single mother who doesn't have the gas money. But she once told me a day when she was washing oranges as the sun streamed onto them. As she peeled one, the smell rose to her face, and she felt she received the Holy Spirit. "He sank into my bones," she recounted. "I lifted my palms upward, feeling filled with love. " Being no theologian, and not even a believer, I am not in a position to offer up theories, but mine is this: people who receive faith directly, as a spontaneous combustion of the soul, have fewer questions. They have been sparked with a faith that is more unshakable than that of those who have been taught.

单选题I saw a television advertisement recently for a new product called an air sanitizer. A woman stood in her kitchen, spraying the empty space in front of her as though using Mace against an imaginary assailant. She appeared very determined. Where others are satisfied with antibacterial-laced sponges, dish soaps, hand sanitizers and telephone wipes, here was a woman who sought to sterilize the air itself. As a casual student of microbiology, I find it hard to escape the absurdity here. This woman is, like any human being, home to hundreds of trillions of bacteria. Bacteria make up a solid third, by weight, of the contents of her intestines. If you were to sneak into her bathroom while she was showering—and based on my general impression of this woman from the advertisement, I don't recommend this—and secret away a teaspoon of the water at her feet, you would find some 820 billion bacteria. Bacteria are unavoidably, inevitably—and, usually, utterly benignly—a part of our world. The fantasy of a germ-free home is not only absurd, but it is also largely pointless. Unless you share your home with someone very old, very young (under 6 months) or very ill, the few hundred bacteria on a countertop, doorknob or spoon pose no threat. The bacteria that cause food poisoning, the only significant rational bacterial worry in the average home, need to multiply into the thousands or millions before they can overwhelm your immune system and cause symptoms. The only way common food poisoning bacteria can manage this is to spend four or five hours reproducing at room temperature in something moist that you then eat. If you are worried about food poisoning, the best defense is the refrigerator. If you don't make a habit of eating perishable food that has been left out too long, don't worry about bacteria. Viruses are slightly different. You need only pick up a few virus particles to infect yourself with a cold or flu, and virus particles can survive on surfaces for days. So disinfecting the surfaces in the home should, in theory, reduce the chances of picking up a bug. In practice, the issue is less clear. A study by Dr. Elaine Larson at the Columbia School of Nursing called into question the usefulness of antibacterial products for the home. In New York, 224 households, each with at least one preschooler, were randomly assigned to two groups. One group used antibacterial cleaning, laundry and hand-washing products. The other used ordinary products. For 48 weeks, the groups were monitored for seven symptoms of colds, flu and food poisoning—and found to be essentially the same. According to Dr. Gerba' s research, an active adult touches an average of 300 surfaces every 30 minutes. You cannot win at this, You will become obsessive-compulsive. Just wash your hands with soap and water a few times a day, and leave it at that.

单选题 How many things can you see in the night sky? A lot! On a clear night you might see the Moon, some planets, and thousands of sparkling stars. You can see even more with a telescope. You might see stars where before you only saw dark space. You might see that many stars look larger than others. You might see that some stars that look white are really red or blue. With bigger and bigger telescopes you can see more and more objects in the sky. And you can see those objects in more and more details. But scientists believe there are some things in the sky that we will never see. We won't see them with the biggest telescope in the world, on the clearest night of the year. That's because they're Invisible. They're the mysterious dead stars called black holes. You might find it hard to imagine that stars die. After all, our Sun is a star. Year after year we see it up in the sky burning brightly, giving us heat and light. The Sun certainly doesn't seem to be getting old or weak. But stars do burn out and die after billions of years. As a star's gases burn, they give off light and heat. But when the gas runs out, the star stops burning and begins to die. As the star cools, the outer layers of the star pull in toward the center. The star squashes into a smaller and smaller ball. If the star was very small, the star ends up as a cold. dark ball called a black dwarf. If the star was very big, it keeps squashing inward until it's packed together tighter than anything in the universe. Imagine if the each were crushed until it was the size of a tiny marble. That's how tightly this dead star, a black hole is packed. What pulls the star in toward its center with such power?. It's the same force that pulls you down when you jump--the force called gravity. A black hole is so tightly packed that its gravity sucks in everything--even light. The light from black hole can never come back to your eyes. That's why you see nothing but blackness. So the next time you stare up at the night sky, remember: there's more in the sky than meets the eyes! Scattered in the silent darkness are black holes--the great mystery of space.

单选题Learning a language is not for everyone. Some people find it very difficult and stressful; others actually enjoy the mental challenge and still others(although these are rare people)find it easy to learn a foreign language. Recently, there has been a lot of interest in trying to define the characteristics of a " good" language learner. Here are four examples—can you select the person who is likely to make the best language learner from these descriptions of their needs and personalities? Perhaps it is best to take a typical example at the outset. Fred Brown had to retire last year because of a bad heart. He went to Spain for a holiday and decided he liked the country and the people so much that he would like to learn the language. He already speaks good French and a little Italian and he thinks these will give him a head start in learning another Latin language. He sees language leaning as a detective game; He hunts for cines and likes to find the answers himself. He knows that language learning is hard work, but he gives himself a little to learn each day. He listens to himself and usually knows when he has made a mistake. He knows exactly what sort of Spanish he wants to learn and is only interested in that. Mary Green has friends in Athens and she has been to Greece several times. Through her friends she met a Greek working in London and now they are engaged to be married. They plan to live in London but she feels she must learn Greek to talk to her future in-laws. She is going to Greek cookery classes as well. She says she is "hopeless at languages" and she hated the French teacher at school. She thinks language is all about talking and she tries to experiment with the language she knows:She takes risks. She is rather lazy about reading Greek and "switches off" when she sees it written down. She finds the classes a bit boring because she is not learning the things she wants to leam but she has not spoken to the teacher about this. In total contrast to someone who has the need to integrate into a family situation, however, is John Freeman. John"s company is starting to sell sportswear in France next May and John will have to visit Marseilles four times a year. There will be a local agent so he will not have to negotiate in French. He has been to France on holiday three times and knows a few words already. He enjoyed the sunshine but doesn"t really like foreigners:" They"re all a funny lot. " He is a very precise person who always likes to be accurate and doesn"t like to make a fool of himself. He does not speak any other languages and is motivated to learn French because of his work. He knows that language can be described as a series of rules and he tries hard to learn the system. He likes the teacher to translate so that he can be sure he has understood exactly what every word means. He is not interested in wasting his time guessing. He has not thought about what kind of French he needs to learn. Jane Smith, on the other hand, hasn"t even started work so she won"t have the strong motivation that working in a language gives people who are trying to sell their products. However, she doesn"t think that foreigners are strange people and she isn"t frightened of making mistakes because " it"s all a bit of fun". She has now finished her first school examinations and, although she is going on to study science in the 6th Form, she doesn"t want to forget the German she has studied. She can"t bear writing, though, and is impatient with herself when she makes grammatical mistakes. She doesn"t really know why she is continuing to leam and she has already said that if her German studies take up too much of her time, she will drop them and focus on "real" work. All of these learners have their own reasons and they are all different in how they approach the task and what they think learning is all about. The experts" view is that people who have a clear idea of the reasons for learning will do well and, on that basis, Fred Brown, John Freeman and Mary Green are clearly advantaged. However, it is also true that those who take risks and experiment do well and regular exposure to the language do well and here, of courses, John and Mary may have the edge over people like Jane. There"s also a case to be made that for those who enjoy learning and don"t care too much about making mistakes, success can come easily.
