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.

单选题The man in the comer confessed to ______ a lie to the manager of the company.

单选题As soon as it was revealed that a reporter for progressive magazine had discovered bow to make a hydrogen bomb, a group of firearm(火器) fans formed the National Hydrogen Bomb Association, and they are now lobbying against any legislation to stop Americans from owning one. "The Constitution," said the associationes spokesman, "gives everyone the right to own arms. It doesn't spell out what kind of arms. But since anyone can now make a hydmgen bomb, the public should be able to buy it to protect theraselves." "Don't you think it's dangerous to have one in the house, particularly where there are children around?" "The National Hydrogen Bomb Association hopes to educate people in the safe handling of this type of weapon. We are instrueting owners to keep the bomb in a locked cabinet and the fuse(导火索) separately in a drawer." "Some people consider the hydrogen bomb a very fatal weapon which could kill somebody." The spokesman said, "Hydrogen bombs don't kill people--people kill people. The bomb is for selfpro-tection and it also has a deterrent effect. If somebody knows you have a nuelear weapon in your house, they're going to think twice about breaking in." "But those who want to ban the bomb for American citizens claim that if you have one locked in the cabinet, with the fuse in a drawer, you would never be able to assemble it in time to stop an intruder(侵入者)." "Another argument against allowing people to own a bomb is that at the moment it is very expensive to build one So what your association is backing is a program which would allow the middle and upper classes to acquire a bomb while poor people will be left defenseless with just handguns./

单选题{{B}}Passage Four{{/B}} An Ohio State University study has linked behavior in young children with the type of job their mother has. Mothers with complex occupations that are self-directed and require working with other people tended to have offspring with relatively low levels of behavior problems. The opposite held true when the jobs were routine, closely supervised, and dealt with things, rather than people. "A job that challenges and interests a mother and gives her an opportunity to exercise judgment and solve problems clearly has positive consequences for her children's behavior," indicates associate professor of sociology Elizabeth Menaghan. Occupations with more positive conditions include management, sales, and teaching positions. Jobs that may be related to increased child behavior problems include book-keeping, food service, and assembly line positions. Women who are supervised closely at work and made to follow strict orders may be more likely to use this same style in raising their kids. They may emphasize obedience to parental authority and the potential for physical punishment. "We believe that the choice of such a parenting style may increase the frequency of behavior problems in children." On the other hand, mothers whose jobs are less controlled by supervisors and who must work closely with other people probably rely less on physical punishment, instead encouraging children to think about consequences of their actions and take responsibility for their behavior. Such an approach encourages youngsters to follow parental demands even when they aren't being supervised because they have accepted parental values as their own. Moreover, mothers whose jobs don't involve constant supervision "develop problem-solving skills that they can bring to other parts of their life". The research also found that those who have more challenging and interesting jobs provide better home environments for their children. The mothers give their offspring more intellectual stimulation and emotional support, and this, in turn, is linked to fewer behavior problems.

单选题 As people continue to grow and age, our body systems continue to change. At a certain point in your life your body systems will begin to weaken. Your joints may become stiff. It may become more difficult for you to see and hear. The slow change of aging causes our bodies to lose some of their ability to bounce back from disease and injury. In order to live longer, we have always tried to slow or stop this process that leads us toward the end of our lives. Many factors contribute to your health. A well-balanced diet plays an important role. The amount and type of exercise you get is another factor. Your living environment and the amount of stress you are under is yet another. But scientists studying senescence (衰老) want to know: Why do people grow old? They hope that by examining the aging process on a cellular level medical science may be able to extend the length of life.

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.
