单选题 Protests at the use of animals in research have taken a new and fearful character in Britain with attempted murder of two British scientists by the terrorist technique of the pre-planted carbomb. The research community will rightly be alarmed at these developments, which have two aims: to draw public attention and to frighten people working in research with animals. The scientists insist that everything should be done to identify those responsible for the crimes and to put them on trial. The Defense Research Society has taken the practical step of offering a reward of $10,000 for information leading to those responsible, but past experience is not encouraging. People are unlikely to be tempted by such offers. The professional police will similarly be confronted by the usual problem of finding a needle in a haystack. That is why the intellectual community in Britain and elsewhere must act more actively in its own defense. There are several steps that can be taken, of which the chief one is to demand of all the organizations that exist with the declared aims of safeguarding the interests of animals that they should declare clearly where they stand on violence towards people. And it will not be enough for the chairman and chairwoman of these organizations to make placatory statements on behalf of all their members. These people should also undertake that it will be a test of continuing membership in their organizations that members and would-be members should declare that they will take no part in acts of violence against human beings. Even such undertakings would be fully effective: people, after all, can lie. But at least they would distinguish the organizations entitled to a continuing voice in the dialogue with the research community about the rights of animals in research from the organizations that deserve no say.

单选题A Dutch review of prior research reveals that the more physically active school-aged children are, the better they fare in the classroom. Most of the studies in the review had been 28 in the United States, while one came out of Canada and the other out of South Africa. The findings are published in the January issue of the Archives of Pediatrics Adolescent Medicine. 'We found strong evidence of a 29 positive relationship between physical activity and academic performance,' the researchers, led by Amika Singh of the Vrije Universiteit University Medical Center at the EMGO Institute for Health and Care Research in Amsterdam, the Netherlands, said in a journal news release. 'The findings of one high-quality intervention study and one high-quality observational study 30 that being more physically active is positively related to improved academic performance in children,' the authors noted. Fourteen studies were analyzed; they 31 in size from about 50 participants to as many as 12000 and 32 children between the ages of 6 and 18. The investigators noted that increases in blood and oxygen flow to the brain that accompanies exercise may play a role in improving classroom performance. The suggestion is that the dynamic prompts an increase in levels of hormones (荷尔蒙) 33 for reducing stress and boosting mood, while at the same time prompting the 34 of new nerve cells and synapse (神经元) flexibility. The Dutch team cautioned, however, that more rigorous work is needed to confirm the connection. ' 35 few studies of high methodological quality have explored the relationship between physical activity and academic performance,' they 36 . 'More high-quality studies are needed on the dose-response relationship between physical activity and academic performance and on the explanatory mechanisms, using 37 and valid measurement instruments to assess this relationship accurately.'
