单选题{{B}}21-25{{/B}} Not too many decades ago it seemed "obvious" both to the general public and to sociologists that modern society has changed people's natural relations, loosened their responsibilities to kin (亲戚) and neighbors, and substituted in their place superficial relationships with passing acquaintances. However, in recent years a growing body of research has revealed that the "obviousness" is not tree. It seems that if you are a city resident, you typically know a smaller proportion of your neighbors than you do if you are a resident of a smaller community. But, for the most part, this fact has few significant consequences. It does not necessarily follow that if you know few of your neighbors you will know no one else. Even in very large cities, people maintain close social ties within small, private social worlds. Indeed, the number and quality of meaningful relationships do not differ between more and less urban people. Small-town residents are more involved with kin than big-city residents. Yet city dwellers compensate by developing friendships with people who share similar interests and activities. Urbanism may produce a different style of life, but the quality of life does not differ between town and city. Nor are residents of large communities any likelier to display psychological symptoms of stress or alienation, a feeling of not belonging, than are residents of smaller communities. However, city dwellers do worry more about crime, and this leads them to a distrust of strangers. These findings do not imply that urbanism makes little or no difference. If neighbors are strangers to one another, they are less likely to sweep the sidewalk of an elderly couple living next door or keep an eye out for young troublemakers. Moreover, as Wirth suggested, there may be a link between a community's population size and its social heterogeneity (多样性). For instance, sociologists have found that the size of a community is associated with bad behavior including gambling, drugs, etc. Large-city urbanites are also more likely than their small-town counterparts to have a cosmopolitan (见多识广者的) outlook, to display less responsibility to traditional kinship roles, to vote for leftist political candidates, and to be tolerant of nontraditional religious groups, unpopular political groups, and so-called undesirables. Everything considered, heterogeneity and unusual behavior seem to be outcomes of large population size.

单选题 A major reason for conflict in the animal world is territory. The male animal {{U}} {{U}} 1 {{/U}} {{/U}}an area. The size of the area is sufficient to provide food for him, his {{U}} {{U}} 2 {{/U}} {{/U}}and their offspring. Migrating birds, for example, {{U}} {{U}} 3 {{/U}} {{/U}}up the best territory in the order of "first come, first {{U}} {{U}} 4 {{/U}} {{/U}}." The late arrivals may acquire {{U}} {{U}} 5 {{/U}} {{/U}}territories, but less food is available, or they are too close to the {{U}} {{U}} 6 {{/U}} {{/U}}of the enemies of the species. {{U}} {{U}} 7 {{/U}} {{/U}}there is really insufficient food or the danger is very great, the animal will not {{U}} {{U}} 8 {{/U}} {{/U}}. In this way, the members of the species which are less fit will not have offspring. When there is conflict {{U}} {{U}} 9 {{/U}} {{/U}}. territory, animals will commonly use force, or a {{U}} {{U}} 10 {{/U}} {{/U}}of force, to decide which will stay and which will go. It is interesting to note, however, that animals seem to use {{U}} {{U}} 11 {{/U}} {{/U}}the minimum amount of force {{U}} {{U}} 12 {{/U}} {{/U}}to drive away the intruder. There is usually no killing. In the {{U}} {{U}} 13 {{/U}} {{/U}}of those animals which are capable of doing each other great harm, {{U}} {{U}} 14 {{/U}} {{/U}}is a system for the losing animal to show the winning animals that he {{U}} {{U}} 15 {{/U}} {{/U}}to submit. When he shows this, the {{U}} {{U}} 16 {{/U}} {{/U}}normally stops fighting. Animals (especially birds), which can easily escape from conflict seem to have {{U}} {{U}} 17 {{/U}} {{/U}}obstacle against killing, and equally no mechanism {{U}} {{U}} 18 {{/U}} {{/U}}submission. The losing bird simply flies away. However, if two doves are {{U}} {{U}} 19 {{/U}} {{/U}}in a cage, and they start fighting, they will continue to fight until one kills the other. We all think of the dove as a symbol of peace and, in its natural habitat, it is peaceful. But the "peace" mechanism does not {{U}} {{U}} 20 {{/U}} {{/U}}in a cage.

单选题All her hard work ______ in the end, and she finally passed the exam. A. showed off B. paid off C. left off D. kept off

单选题Like many of my generation, I have a weakness for hero worship. At some point, however, we all begin to question our heroes and our need for them. This leads us to ask: What is a hero? Despite immense differences in cultures, heroes around the world generally share a number of characteristics that instruct and inspire people. A hero does something worth talking about. A hero has a story of adventure to tell and a community who will listen. But a hero goes beyond mere fame. Heroes serve powers or principles larger than themselves. Like high-voltage transformers, heroes take the energy of higher powers and step it down so that it can be used by ordinary people. The hero lives a life worthy of imitation. Those who imitate a genuine hero experience life with new depth, enthusiasm, and meaning. A sure test for would-be heroes is what or whom do they serve? What are they willing to live and die for? If the answer or evidence suggests they serve only their own fame, they may be famous persons but not heroes. Madonna and Michael Jackson are famous, but who would claim that their fans find life more abundant? Heroes are catalysts (催化剂) for change. They have a vision from the mountaintop. They have the skill and the charm to move the masses. They create new possibilities. Without Gandhi, India might still be part of the British Empire. Without Rosa Parks and Martin Luther King, Jr. , we might still have segregated (隔离的) buses, restaurants, and parks. It may be possible for large-scale change to occur without leaders with magnetic personalities, but the pace of change would be slow, the vision uncertain, and the committee meetings endless.

单选题 By adopting a few simple techniques, parents who read to their children can greatly increase their children's language development. It is surprising but true. How parents talk to their children makes a big difference in the children's language development. If a parent encourages the child to actively respond to what the parent is reading, the child's language skills increase. A study was done with 30 three-year-old children and their parents. Half of the children participated in the experimental study; the other half acted as the control group. In the experimental group, the parents were given a two-hour training session in which they were taught to ask open-ended questions rather than yes-or-no questions. For example, the parent should ask, "What is the doggie doing? " rather than "Is the doggie running away?" The parents in the experimental group were also instructed in how to help children find answers, how to suggest alternative possibilities and how to praise correct answers. At the beginning of the study, the children did not differ in measures of language development, but at the end of one month, the children in the experimental group showed 5.5 months ahead of the control group on a test of verbal expression and vocabulary. Nine months later, the children in the experimental group still show an advance of 6 months over the children in the control group.

单选题Recently, the American Heart Association surveyed 1,000 people nationwide about their thoughts on sodium and heart health. 61~ said that they believed sea salt was a low-sodium alternative to table salt. They can be forgiven for thinking so. Sea salt is marketed as a healthy food, added to soups, potato chips and a wide variety of packaged snacks labeled "low sodium", "all natural" and "healthy". But in reality, sea salt and table salt are not terribly different, at least chemically. The real differences are in how the two are used in cooking. Table salt comes from underground salt deposits. Companies that sell it typically add something to keep it from clumping(结块). During processing, table salt is stripped of many of its natural minerals. Sea salt, on the other hand, is made from evaporated seawater. With little processing, it retains most of its minerals, which some cooks say give it a better flavor. But both contain the same amount of sodium chloride (氧化的) by weight, which means they contribute equally to total sodium consumption and have the same effect on blood pressure. Officials recommend that adults consume no more than 2,300 milligrams of sodium a day, equivalent to a teaspoon of salt. You should eat less if you are black, hypertensive(患高血压的) or older than 40. Yet most Americans consume more than double the amount they need, mostly from processed foods, so it is best to limit salt-of any kind.
