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Real policemen hardly recognize any resemblance (类同之处) between their lives and what they see on TV—if they ever get home in time. Them are similarities, of course, but the cops(警官) don't think much of them. The first difference is that a policeman's real life revolves round the law. Most of his training is in criminal law. He has to know exactly what actions are crimes and what evidence can be used to prove them in court. He has to know nearly as much law as a professional lawyer, and what is more, he has to apply it on his feet, in the dark and rain, running down an alley after someone he wants to talk to. Little of his time is spent in chatting to scanty-clad (穿衣不多的) ladies or in dramatic confrontations with desperate criminals. He will spend most of his working life typing millions of words on thousands of forms about hundreds of sad, unimportant people who are guilt or not—of stupid, petty crimes.

单选题Jessica Bucknam shouts "tiao! "(tee—ow) and her fourth-grade students jump. "Dun!"(doo—wen) she commands, and they crouch(蹲). They giggle(吃吃地笑) as the commands keep coming in Mandarin Chinese. Half of the 340 students at the K-5 school are enrolled in the program. They can contine studying Chinese in middle and high schools. The goal.. to speak like natives. About 24,000 American students are currently learning Chinese. Most are in high schools. But the number of younger students is growing in response to China's emergence as a global superpower. "China has become a strong partner of the United States," says Mary Patterson, Woodstock's principal. "Children who learn Chinese at a young age will have more opportunities for jobs in the future." Isabel Weiss, 9, isn't thinking about the future. She thinks learning Chinese is fun. "when you hear peo- ple speaking in Chinese, you know what they're saying,' she says. "And they don't know that you know. '

单选题Happiness is becoming a huge area in psychological research and even in government policy, with the UK government exploring a "happiness index". It"s tough, though, to define exactly what happiness is, and what makes us happy. There are two broad ways of looking at happiness: short-term happiness (a great cookie, a bottle" of wine) and long-term happiness (financial security, achieving your goals). Both types of happiness are valid, and important. The problem is, they"re often in competition. Let"s say you"ve got a goal of losing 50 pounds this year. You know you"d be happier and healthier if you weren"t carrying that extra weight. To achieve long-term happiness, you need to go on a diet. In the short-term, though, it"s not that easy. A chocolate cake, or a large glass of wine, might seem like just the thing to cheer you up at the end of a long day—or to celebrate with friends. It"s the same with lots of other goal. If you"ve got a tendency to prioritize long-term happiness at the expense of day-to-day pleasures, you should start looking for some small ways to bring a little joy back into your life. I"m not suggesting that you go out and get drunk every night, or that you stuff yourself with cake. There are plenty of other ways to enjoy yourself. Don"t pin ai1 your hopes of happiness on some far-off future, though. There"s no point working a 60-hour week and making yourself thoroughly miserable in the belief that things will be perfect as soon as you"re making a six-figure salary.
