单选题The economy in the United States is heavily dependent on aluminum, a material widely used in the construction of buildings and in making such diverse things as cars, airplanes, and food containers. In 1979 Americans used over five million tons of new aluminum, and one and a half million tons of recycled aluminum. Some ninety percent of the bauxite (矾士) ore from which new aluminum is normally derived had to be imported to meet the demand. Poorer ores are abundant in the United States, however, researchers at Purdue University may recently have found a way to obtain aluminum magnetically from these. Although aluminum is not attracted by ordinary magnets, under special conditions it becomes temporarily "paramagnetic", or very weakly responsive to a magnetic field. This is achieved by immersing ore particles in water to which certain salts have been added and then filtering the ore through steel wool in the presence of a strong magnetic field. It is hoped that this technique will reduce the amount of high-grade aluminum the United States must import.

单选题 Why Integrity Matters What is Integrity? A. 'Integrity' is defined as 'adherence to moral and ethical principles; honesty.' The key to integrity is consistency—not only setting high personal standards for oneself (honesty, responsibility, respect for others, fairness) but also living up to those standards each day. One who has integrity is bound by and follows moral and ethical standards even when making life's hard choices, choices which may be clouded by stress, pressure to succeed, or temptation. B. What happens if we lie, cheat, steal, or violate other ethical standards? We feel disappointed in ourselves and ashamed. But a lapse of integrity also affects our relationships with others. Trust is essential in any important relationship, whether personal or professional. Who can trust someone who is dishonest or unfair? Thus, integrity must be one of our most important goals. Risky Business C. We are each responsible for our own decisions, even if the decision-making process has been undermined by stress or peer pressure. The real test of character is whether we can learn from our mistake, by understanding why we acted as we did, and then exploring ways to avoid similar problems in the future. D. Making ethical decisions is a critical part of avoiding future problems. We must learn to recognize risks, because if we can't see the risks we're taking, we can't make responsible choices. To identify risks, we need to know the rules and be aware of the facts. For example, one who doesn't know the rules about plagiarism may accidentally use words or ideas without giving proper credit, or one who fails to keep careful research notes may unintentionally fail to quote and cite sources as required. But the fact that such a violation is 'unintentional' does not excuse the misconduct. Ignorance is not a defense. But Everybody Does It E. Most people who get in trouble do know the rules and facts, but manage to fool themselves about the risks they're taking by using excuses: 'Everyone else does it,' 'I' m not hurting anyone,' or 'I really need this grade.' Excuses can get very elaborate: 'I know I'm looking at another's exam, even though I'm supposed to keep my eyes on my own paper, but that's not cheating because I'm just checking my answers, not copying.' We must be honest about our actions, and avoid excuses. If we fool ourselves into believing we're not doing anything wrong, we can't see the real choice we're making— and that leads to bad decisions. F. To avoid fooling yourself, watch out for excuses and try this test: Ask how you would feel if your actions were public, and anyone could be watching over your shoulder. Would you feel proud or ashamed of your actions? If you'd rather hide your actions, that's a good indication that you're taking a risk and rationalizing it to yourself. Evaluating Risks G. To decide whether a risk is worth taking, you must examine the consequences, in the future as well as right now, negative as well as positive, and to others as well as to yourself. Those who take risks they later regret usually focus on immediate benefits ('what's in it for me'), and simply haven't considered what might go wrong. The consequences of getting caught are serious, and may include a '0' on a test or assignment; an 'F' in the class; Suspension or Dismissal from school; transcript notation; and a tarnished reputation. In fact, when you break a rule or law, you lose control over your life, and give others the power to impose punishment: you have no control over what that punishment might be. This is an extremely precarious and vulnerable position. There may be some matters of life and death, or highest principle, which might justify such a risk, but there aren't many things that fall in this category. Getting Away With It—Or Not H. Those who don't get caught pay an even higher price. A cheater doesn't learn from the test, depriving him/herself of an education. Cheating undermines confidence and independence: the cheater is a fraud, and knows that without dishonesty, he/she would have failed. Cheating destroys self-esteem and integrity, leaving the cheater ashamed, guilty, and afraid of getting caught. Worst of all, a cheater who doesn't get caught the first time usually cheats again, not only because he/she is farther behind, but also because it seems 'easier.' This slippery slope of eroding ethics and bigger risks leads only to disaster. Eventually, the cheater gets caught, and the later he/she gets caught, the worse the consequences. Students have been dismissed from school because they didn't get this simple message: Honesty is the ONLY policy that works. Cheating Hurts Others, Too I. Cheaters often feel invisible, as if their actions 'don't count' and don't really hurt anyone. But individual choices have a profound cumulative effect. Cheating can spread like a disease, and a cheater can encourage others just by being seen from across the room. Recent statistics suggest 30% or more of college students cheat. If a class is graded on a curve, cheating hurts others' grades. Even if there is no curve, cheating 'poisons' the classroom, and others may feel pressured to join in. ('If I don't cheat, I can't compete with those who do.') Cheating also has a destructive impact on teachers. The real reward of good teaching is seeing students learn, but a cheater says, 'I'm not interested in what you're trying to teach; all I care about is stealing a grade, regardless of the effect on others.' The end result is a blatant and destructive attack on the quality of your education. Finally, cheating can hurt the reputation of the university, and harm those who worked hard for their degree. Why Integrity Matters J. If cheating becomes the norm, then we are in big trouble. We must rely on the honesty and good faith of others every day. If not, we couldn't put money in the bank, buy food, clothing, or medicine from others, drive across a bridge, get on a plane, go to the dentist—the list is endless. There are many examples of the vast harm that is caused when individuals forget or ignore the effect their dishonesty can have. The savings and loan scandal, the stock market and junk bond swindles, and, of course, Watergate, have undermined the faith of many Americans in the integrity of political and economic leaders and society as a whole. Such incidents take a tremendous toll on our nation's economy and our individual well-being. For example, but for the savings and loan debacle, there might be funds available to reduce the national debt and pay for education. K. In sum, we all have a common stake in our school, our community, and our society. Our actions do matter. It is essential that we act with integrity in order to build the kind of world in which we want to live.

单选题The question of ethics in the legal profession is one that has plagued the industry since its inception. The common image of an attorney is one who will resort to any unethical trick to twist the laws to fit his purposes. In the more specific industry of criminal law, defense attorneys are often criticized for advocating on behalf of defendants who are "obviously guilty," thus becoming roadblocks on the path to justice. Much to the contrary, however, defense attorneys provide a valuable serve that should earn them praise, not scorn. While it is true that every lawyer will do everything within his power to interpret the laws in the manner most beneficial to his client, such a characterization is by no means limited to defense attorneys. The prosecutor will do the same thing, employing all his legal knowledge and know-how to establish the guilt of the defendant. In this respect, the vague nature of the law is highlighted, and it becomes a virtual necessity for each side to use every tool at their disposal, on the assumption that the other side will also use every tool at his. The net result emerges as a positive, in which the tricks of the opposing attorneys cancel one another out, leaving only the truth, clearer and devoid of manipulation, presented for the jury's consideration. Further, the defense attorney is a vital element of the American judicial system, in that without him the defendant would stand no chance whatsoever. Under the constitution, even the most "obvious guilty" defendants are guaranteed the right to a fair trial, involving someone able and willing to advocate on his behalf. Of course, there are bad apples in the industry who are unethical and care nothing for actual justice, and whose only concerns are their wallets. Generally speaking, however, without defense attorneys, the system would crumble into a mere machine in which defendants are assumed guilty, without a chance to argue or prove otherwise, and many innocent people falsely charged with crimes would be severely punished for transgressions that they didn't commit. It is a basic fact that the adversarial system of justice in the United States is necessary in order to ensure the fairest and most unbiased presentation and evaluation of the facts possible. Without defense attorneys, that system cannot be carried out, and would result in a loss of the civil liberties that the nation enjoys and treasures. To that end, all of those who make that process a reality, including defense attorneys, deserve our support and admiration, not our suspicion and disdain.
