单选题Anne Whitney, a sophomore at Colorado State University, first had a problem taking test when she began college. "I was always well prepared for my tests. Sometimes I studied for weeks before a test. Yet I would go in to take the test, only to find I could not answer the questions correctly. I would blank out because of nervousness and fear. I couldn't think of the answer. My low grades on the tests did not show what I knew to the teacher." Another student in microbiology had similar experiences. He said, "My first chemistry test was very difficult. Then, on the second test, I sat down to take it, and I was so nervous that I was shaking. My hands were moving up and down so quickly that it was hard to hold my pencil. I knew the material and I knew the answers. Yet I couldn't even write them down." These two young students were experiencing something called test anxiety. Because a student worries and is uneasy about a test, his or her mind does not work as well as it usually does. The student cannot write or think clearly because of the extreme tension and nervousness. Although poor grades are often a result of poor study habits, sometimes test anxiety causes the low grades. Recently, test anxiety has been recognized as a real problem, not just an excuse or a false explanation of lazy students. Special university counseling courses try to help students. In these courses, counselors try to help students by teaching them how to manage test anxiety. At some universities, students take tests to measure their anxiety. If the tests show their anxiety is high, the students can take short courses to help them deal with their tension. These courses teach students how to relax their bodies. Students are trained to become calm in very tense situations. By controlling their nervousness, they can let their minds work easy. Learned information then comes out without difficulty on a test. An expert at the University of California explains, "With almost all students, relaxation and less stress are felt after taking our program. Most of them experience better control during their tests. Almost all have some improvement. With some, the improvement is very great./

单选题 Many people think there is no need to take special care over home security. "I'm all right, I'm insured." Maybe--if you're fully insured. Even then you can never recover the real value you place upon your possessions. But you can't insure against the upset and unhappiness that we all feel if our homes are seriously damaged by some stranger, our windows and doors smashed, our precious possessions ruined. "It won't happen to me." Won't it? A home is broken into almost every minute of the day. Thefts of all kinds, including cars and property stolen, happen twice as frequently. "I've nothing worth stealing." You may think not. But in fact every one has something worth a thief's attention. And we all have things of special value to us even if they're worth little or nothing in cash terms. "I'm only a tenant here." The thief doesn't care whether you're a tenant or an owner-occupier. You're just as likely to be robbed. Have a word with the owner of the house ff you think extra locks and fastenings are necessary. "They'll get in any way." Most thieves are always looking for easy jobs. They are soon discouraged by houses they can't get into quickly and easily. So it's worth taking care. This booklet will help you. It's based on the practical experience of police forces throughout the country. Most of the suggestions will cost you only a few minutes extra time and thought. A few may involve some expense, but this is small compared with the loss and unhappiness you might otherwise suffer. If you are in doubt, ask for free advice from the Crime Prevention Officer at your local police station.

单选题Our physical development is largely directed by the genes that we inherit from our parents. At one time, psychologists waged vigorous debates about how much of our behavior is genetically determined and how much of it is learned. This was known as the nature-nurture controversy. We now know that this "either-or" question is largely meaningless, since behavior depends on the interaction between heredity (遗传) and environment. However, it is also dear that genetic factors do set limits on our behavioral capabilities, as illustrated most dramatically in certain genetically baaed birth disorders. Psychologists working in the field of behavior genetics study how behavior is influenced by biological factors and how favorable or unfavorable environmental conditions can affect an organism' s genetically inherited potential. Genetic theory began around 1865, when Gregor Mendel reported on his experiments with garden peas. Mendel showed that heredity involved the passing on of specific organic factors, not the simple blending of the parents' characteristics. These specific factors might produce visible characteristics in the offspring(后代), or they might simply be carried for possible transmission to another generation. In any case, the offspring of one set of parents did not all inherit the same traits. Early in the twentieth century, geneticists made an important distinction between genotype and phenotype. Genotype refers to the specific genetic makeup of an individual, while phenotype refers to the observable characteristics produced by that genetic endowment(才能). Genotype and phenotype axe not identical because not every gene is expressed in a visible trait and bemuse the expression of a genotypic trait may be modified by the environment. An individual's genetic coding is like the catalog of a giant library. Some of the coded directives are used on one occasion, some on another. Some are never used at all, either, because they are contradicted by stronger genetic directives or because the environment never calls them forth. For example, geneticists have discovered that chickens have retained the genetic code for teeth, yet, because the code is prevented from being expressed, hens' teeth remain a cliche for scarcity.

单选题 After the violent earthquake that shook Los Angeles in 1994, earthquake scientists had good news to report: the damage and death toll could have been much worse. More than 60 people died in this earthquake. By comparison, an earthquake of similar intensity that shook America in 1988 claimed 25, 000 victims. Injuries and deaths were relatively less in Los Angeles because the quake occurred at 4:31 a.m. on a holiday, when traffic was light on the city's highways. In addition, changes made to the construction codes in Los Angeles during the last 20 years have strengthened the city's buildings and highways, making them more resistant to quakes. Despite the good news, civil engineers aren't resting on their successes. Pinned to their drawing boards are blueprints for improved quake-resistant buildings. The new designs should offer even greater security to cities where earthquakes often take place. In the past, making structures quake-resistant meant firm yet flexible materials, such as steel and wood, that bend without breaking. Later, people tried to lift a building off its foundation, and insert rubber and steel between the building and its foundation to reduce the impact of ground vibrations. The most recent designs give buildings brains as well as concrete and steel supports, called smart buildings. The structures respond like living organisms to an earthquake's vibrations. When the ground shakes and the building tips forward, the computer would force the building to shift in the opposite direction. The new smart structures could be very expensive to build. However, they would save many lives and would be less likely to be damaged during earthquakes.

单选题Americans live in a style-conscious culture even elementary school children know the difference between Air Jordans and the cheaper imitations. By the time they enter junior high school, most American adolescents are already highly skilled at distinguishing between brand names. The real lesson young Americans learn is that they live in a world where it matters what brand of clothes or furniture or car they buy. It matters what style of music they listen to, how they wear their hair, whether they"re tattooed or pierced, and what kind of food they like to eat. Even everyday use—objects from staplers to tooth brushes to laptop computers matter too. In many ways, it seems that such a concern for personal style and the appearance of objects is shallow and trivial. After all, what does it really matter whether or not someone"s clothes or music or computer is at the cutting edge of style? Why should anyone care? One reason is that style is a guide to economic and social class in America Style identities. Whether consciously or unconsciously, we make judgments about people based on their appearance and their style. Simply by growing up in American culture, we acquire a sense of the style appropriate to different walks of life—how, for example, a high school teacher, a business executive, a truck driver, or a rock star ought to look. Style communicates messages about economic and social class precisely because we share with others cultural codes that define what"s normal and expected. For example, we expect wealthy professionals in metropolitan areas to be museum members, go to the opera, and enjoy gourmet food and fine wine. On the other hand, we are likely to expect that working-class men in the Midwest drink beer, listen to classic rock, and support their local pro-football team. This doesn"t mean that everyone in a particular social group conforms to these cultural codes. What it does indicate, however, is that style carries cultural meanings that go far beyond individual likes and dislikes. Style, in other words, is linked to the way of life that identifies groups of people, cultures, and subcultures. If the styles we adopt seem to be freely taken personal choices, they are contained nonetheless in a larger system of cultural codes that organize the way we think about identity, social status, prestige, good (and bad) taste, tradition, and innovation. Fashion designers, graphic designers, and product designers understand this intimate connection between style and identity. They design everything from corporate logos and brand trademarks to the latest style of jeans and athletic shoes to computers and cars. Their job is to match styles to people"s identities and, at the same time, to create styles that offer people new identities.
