2、鱼肝油与心脏病 V1(from morningqu 600+) 逻辑有道吃鱼能降低心脏病发病率但芬兰吃很多这种鱼的人却比别人发病风险高 找支持 考古 (from nowwsy) 鱼肝油能抑制心脏病,可是在芬兰,吃鱼的人们反而心脏病发病几率高,研究发现原来是长期吃鱼,导致人体积聚的汞的含量高倒是心脏病发病几率高的阿。。。问其他帮助分析这个结果的实验,我没看懂题目想问什么,答案也不知所云,好几个假设。。 我记得一个类似的题目。 7. Recent evidence appears to contradict earlier findings that suggested that those who are physically fit cope better with stressful real-life events. Of a group of healthy women, those randomly assigned to a ten-week program of aerobic exercises performed no better in laboratory tests simulating stressful situations than did the subgroup assigned to a program without exercise. Which of the following, if true, provides evidence for determining whether physical fitness makes one react better to stress? (A) Superior reaction to laboratory stress situations was found to be more prevalent among women than among men. (B) Healthy men, after training six months in weight lifting, encountered fewer potentially stressful situations in the subsequent six months. (C) Subjects following a regimen during which they perfected their skills in a variety of relaxation techniques found that their lives seemed calmer after they began the regimen. (D) College students with previous high levels of stressful life events showed a markedly reduced reaction to such events after training in aerobics for six months. (E) Subjects with a high level of self-esteem more often engaged in physical-fitness regimens than did a control group of subjects with average levels of self-esteem. 答案是D -- by 会员 bonnie0715 (2010/5/27 17:34:24)
