单选题To paraphrase 18th-century statesman Edmund Burke, "all that is needed for the triumph of a misguided cause is that good people do nothing." One such cause now seeks to end biomedical research because of the theory that animals have rights ruling out their use in research. Scientists need to respond forcefully to animal rights advocates, whose arguments are confusing the public and thereby threatening advances in health knowledge and care. Leaders of the animal rights movement target biomedical research because it depends on public funding, and few people understand the process of health care research. Hearing allegations of cruelty to animals in research settings, many are perplexed that anyone would deliberately harm an animal. For example, a grandmotherly woman staffing an animal rights booth at a recent street fair was distributing a brochure that encouraged readers not to use anything that comes from of is tested in animals--no meat, no fur, no medicines. Asked if she opposed immunizations, she wanted to know if vaccines come from animal research. When assured that they do, she replied, "Then I would have to say yes." Asked what will happen when epidemics return, she said, "Don't worry, scientists will find some way of using computers." Such well-meaning people just don't understand. Scientists must communicate their message to the public in a compassionate, understandable way--in human terms, not in the language of molecular biology. We need to make clear the connection between animal research and a grandmother's hip replacement, a father's bypass operation, a baby's vaccinations, and even a pet's shots. To those who are unaware that animal research was needed to produce these treatments, as well as new treatments and vaccines, animal research seems wasteful at best and cruel at worst. Much can be done. Scientists could "adopt" middle school classes and present their own research. They should be quick to respond to letters to the editor, lest animal rights misinformation go unchallenged and acquire a deceptive appearance of truth. Research institutions could be opened to tours, to show that laboratory animals receive humane care. Finally, because the ultimate stakeholders are patients, the health research community should actively recruit to its cause not only well-known personalities such as Stephen Cooper, who has made courageous statements about the value of animal research, but all who receive medical treatment. If good people do nothing, there is a real possibility that an uninformed citizenry will extinguish the precious embers of medical progress.

单选题In recent years, there has been an increasing awareness of the inadequacies of the judicial system in the United States. Costs are staggering both for the taxpayers and the litigants—and the litigants, or parties, have to wait sometimes many years before having their day in court. Many suggestions have been made concerning methods of ameliorating (改善) the situation, but as in most branches of government, changes come slowly. One suggestion that has been made in order to maximize the efficiency of the system is to allow districts that have an overabundance of pending cases to borrow judges from other districts that do not have such a backlog. Another suggestion is to use pretrial conferences, in which the judge meets in his chambers with the litigants and their attorneys in order to narrow the issues, limit the witnesses, and provide for a more orderly trial. The theory behind pretrial conferences is that judges will spend less time on each case and parties will more readily settle before trial when they realize the adequacy of their claims and their opponents" evidence. Unfortunately, at least one study has shown that pretrial conferences actually use more judicial time than they save, rarely result in pretrial settlements, and actually result in higher damage settlements. Many states have now established another method, small-claims courts, in which cases over small sums of money can be disposed of with considerable dispatch. Such proceedings cost the litigants almost nothing. In California, for example, the parties must appear before the judge without the assistance of counsel. The proceedings are quite informal and there is no pleading (辩护)—the litigants need to make only a one-sentence statement of their claim. By going to this type of court, the plaintiff (原告) waives (放弃) any right to a jury trial and the right to appeal the decision.
