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 isn"t 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 are loosening. 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 underprivileged upbringing, by the school that didn"t teach him to read, by the church that failed to reach him with moral guidance, by the parents who didn"t 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. Compared with those in small towns, people in large cities have ______.
A. less self-discipline
B. better sense of discipline
C. more mutual respect
D. less effective government

Imagine a world in which there was suddenly no emotion—a world in which human beings could feel no love or happiness, no terror or hate. Try to imagine the consequences of such a transformation. People might not be able to stay alive: knowing neither joy nor pleasure, neither anxiety nor fear, they would be as likely to repeat acts that hurt them as acts that were beneficial. They could not learn: they could not benefit from experience because this emotionless world would lack rewards and punishments. Society would soon disappear: people would be as likely to harm one another as to provide help and support. Human relationships would not exist: in a world without friends or enemies, there could be no marriage, affection among companions, or bonds among members of groups. Society"s economic underpinnings (支柱) would be destroyed: since earning $10 million would be no more pleasant than earning $10, there would be no incentive to work. In fact, there would be no incentives of any kind. For as we will see, incentives imply a capacity to enjoy them.In such a world, the chances that the human species would survive are next to zero, because emotions are the basic instrument of our survival and adaptation. Emotions structure the world for us in important ways. As individuals, we categorize objects on the basis of our emotions. True we consider the length, shape, size, or texture, but an object"s physical aspects are less important than what it has done or can do to us—hurt us, surprise us, anger us or make us joyful. We also use categorizations colored by emotions in our families, communities, and overall society. Out of our emotional experiences with objects and events comes a social feeling of agreement that certain things and actions are "good" and others are "bad", and we apply these categories to every aspect of our social life—from what foods we eat and what clothes we wear to how we keep promises and which people our group will accept. In fact, society exploits our emotional reactions and attitudes, such as loyalty, morality, pride, shame, guilt, fear and greed, in order to maintain itself. It gives high rewards to individuals who perform important tasks such as surgery, makes heroes out of individuals for unusual or dangerous achievements, such as flying fighter planes in a war, and uses the legal penal (刑法的) system to make people afraid to engage in antisocial acts. It can be inferred from the passage that the economic foundation of society is dependent on ______.
A. the ability to make money
B. the will to work for pleasure
C. the capacity to enjoy incentives
D. the categorizations of our emotional experiences
