单选题 On a four-day trip to Ethiopia, I had a dream. In my dream, I saw two men, one older and one younger, facing one another against a background of temples and pyramids.

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.

单选题Throughout this long, tense election, everyone has focused on the presidential candidates and how they'll change America. Rightly so. But selfishly, I'm more fascinated by Michelle Obama and what she might be able to do, not just for this country, but for me as an African-American woman. As the potential First Lady, she would have the world's attention. And that means that for the first time people will have a chance to get up close and personal with the type of African-American woman they so rarely see. Usually, the lives of black women go largely unexamined. The prevailing theory seems to be that we're all hot-tempered single mothers who can't keep a man. Even in the world of make-believe, black women still can't escape the stereotype of being eye-rolling, oversexed females raised by our never-married, alcoholic(酗酒的) mothers. These images have helped define the way all black women are viewed, including Michelle Obama. Before she ever gets the chance to commit to a cause, charity or foundation as First Lady, her most urgent and perhaps most complicated duty may be simply to be herself. It won't be easy. Because few mainstream publications have done in-depth features on regular African-American women, little is known about who we are, what we think and what we face on a regular basis. For better or worse, Michelle will represent us all. Just as she will have her critics, she will also have millions of fans who usually have little interest in the First Lady. Many African-American blogs have written about what they'd like to see Michelle bring to the White House—mainly showing the world that a black woman can support her man and raise a strong black family. Michelle will have to work to please everyone—an impossible task. But for many African-American women like me, just a little of her poise(沉着), confidence and intelligence will go a long way in changing an image that's been around for far too long.

单选题In bringing up children, every parent watches eagerly the child's acquisition (学会) of each new skill the first spoken words, the first independent steps, or the beginning of reading and writing. It is often tempting to hurry the child beyond his natural learning rate, but this can set up dangerous feelings of failure and states of worry in the child. This might happen at any stage. A baby might be forced to use a toilet too early, a young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural enthusiasm for life and his desire to find out new things for himself. Parents vary greatly in their degree of strictness towards their children. Some may be especially strict in money matters. Others are sever over times of coming home at night or punctuality for meals. In general, the controls imposed represent the needs of the parents and the values of the community as much as the child's own happiness. As regards the development of moral standards in the growing child, consistency is very important in parental teaching. To forbid a thing one day and excuse it the next is no foundation for morality(道德). Also, parents should realize that "example is better than precept". If they are not sincere and do not practise what they preach (说教), their children may grow confused, and emotionally insecure when they grow old enough to think for themselves, and realize they have been to some extent fooled. A sudden awareness of a marked difference between their parents' principles and their morals can be a dangerous disappointment.
