单选题Despite the general negative findings, it is important to remember that all children who live through a divorce do not behave in the same way. The specific behavior depends on the child's individual personality, characteristics, age at the time of divorce, and gender. In terms of personality, when compared to those rated as relaxed and easygoing, children described as temperamental and irritable have more difficulties coping with parental divorce, as indeed they have more difficulties adapting to life changes in general. Stress, such as that found in disrupted families, seems to impair the ability of temperamental children to adapt to their surroundings, the greater the amount of stress, the less well they adapt. In contrast, a moderate amount of stress may actually help an easygoing, relaxed child learn to cope with adversity. There is some relationship between age and children's characteristic reaction to divorce. As the child grows older, the greater is the likelihood of a free expression of a variety of complex feelings, an understanding of those feelings, and a realization that the decision to divorce cannot be attributed to any one simple cause. Self-blame virtually disappears after the age of 6, fear of abandonment diminishes after the age of 8, and the confusion and fear of the young child is replaced in the older child by shame, anger, and self-reflection. Gender of the child is also a factor that predicts the nature of reaction to divorce. The impact of divorce is initially greater on boys than on girls. They are more aggressive, less compliant, have greater difficulties in interpersonal relationships, and exhibit problem behaviors both at home and at school Furthermore, the adjustment problems of boys are still noticeable even two years after the divorce. Girls' adjustment problems are usually, internalized rather than acted out, and are often resolved by the second year after the divorce. However, new problems may surface for girls as they enter adolescence and adulthood. How can the relatively greater impact of divorce on boys than on girls be explained? The greater male aggression and noncompliance may reflect the fact that such behaviors are tolerated and even encouraged in males in our culture more than they are in females. Furthermore, boys may have a particular need for a strong male model of self-control, as well as for a strong disciplinarian parent. Finally, boys are more likely to be exposed to their parents' fights than girls are, and after the breakup, boys are less likely than girls to receive sympathy and support from mothers, teachers, or peers.

单选题BPassage 3/B 　　A wise man once said that the only thing necessary for the triumph of evil is for good men to do nothing. So, as a police officer, I have some urgent things to say to good people. Day after day my men and I struggle to hold back a tidal wave of crime. Something has gone terribly wrong with our once-proud American way of life. It has happened in the area of values. A key ingredient is disappearing, and I think I know what it is: accountability. Accountability is not hard to define. It means that every person is responsible for his or her actions and liable for their consequences.　　Of the many values that hold civilization together—honesty, kindness, and so on, accountability may be the most important of all. Without it, there can be no respect, no trust, no law—and, ultimately, no society.　　My job as a police officer is to impose accountability on people who refuse, or have never learned, to impose it on themselves. But as every policeman knows, external controls on people's behavior are far less effective than internal restraints such as guilt, shame and embarrassment.　　Fortunately there are still communities—smaller towns usually—where schools maintain discipline and where parents hold up standards that proclaim: "In this family certain things are not tolerated—they simply are not done!"　　Yet more and more, especially in our larger cities and suburbs, these inner restraints areloosening. Your typical robber has none. He considers your property his property; he takes what he wants, including your life if you enrage him.　　The main cause of this break-down is a radical shift in attitudes. Thirty years ago, if a crime was committed, society was considered the victim. Now, in a shocking reversal, it's the criminal who is considered victimized: by his under-privileged upbringing, by the school that did not teach him to read, by the church that failed to reach him with moral guidance, by the parents who did not provide a stable home.　　I don' t believe it. Many others in equally disadvantaged circumstances choose not to engage in criminal activities. If we free the criminal, even partly, from accountability, we become a society of endless excuses where no one accepts responsibility for anything. We in America desperately need more people who believe that the person who commits a crime is the one responsible for it.
