17.Being physically active three times a week reduces the odds of being depressed by about 16%,according to new UCL research carried out as part of the Public Health Research Center.The study,published in JAMA Psychiatry,found a two-way relationship between depression and physical activity.People who increased their weekly activity reported fewer depressive symptoms but those with more depressive symptoms were less active,particularly at younger ages.
Researchers followed 11,135 people born in 1958 up until the age of 50,recording depressive symptoms and levels of physical activity at regular intervals in adulthood.They found that each additional activity period per week reduced odds of depression by 6%.In England 19% of men and 26% of women are currently classed as"inactive",and this study suggests that activity could significantly improve their mental as well as physical health.
"Assuming the association is causal,physical activity has a protective effect against depression.If an adult between their twenties and forties who isn't physically active became active 3times per week,they would reduce their risks of depression by about 16%."says Dr.Snehal of the UCL Institute of Child Health,lead author of the study.
Professor Mark,Director of the Public Health Research Center,said,"Many people are already aware of the benefits of physical activity on their general health,but now we are seeing more evidence that suggest it also has a positive effect on a person's mental well-being.The latest research highlights just how important it is to ensure that people are working and living in environments that allow them to be both physically active and mentally healthy."

解答 25.B 写作意图题.本文主要向读者介绍了一项科学研究成果,这项研究主要介绍了身体锻炼与抑郁症之间的联系,故选B.
26.A 细节理解题.根据第二段的People who increased their weekly activity reportedfewer depressive symptoms but those with more depressive symptoms were lessactive可知,增加每周活动的人报告说有较少的抑郁症状,但那些有更多的抑郁症状的是较不活跃的,特别是在年轻的年龄.所以如果人们增加每周锻炼身体的次数,就会有较少的抑郁症状,故选A.
27.D 细节理解题.根据第一段的Being physically active three times a week reducesthe odds of being depressed by about 16%可知,每周锻炼三次,大约降低16%患抑郁症的可能性.所以增加每周锻炼身体的次数,在某种程度上能降低人们患抑郁症的可能性,故选D.
28.B 推理判断题.根据全文尤其是根据第三、四段的内容可知,研究人员记录了出生于1958的11135人直到50岁,在成年期定期记录抑郁症状和身体活动水平.他们发现每周增加活动期间减少抑郁症的几率为6%.如果一个在二十多岁和四十多岁不太活动的成年人变为每周活动3次,他们会减少约16%的抑郁症风险.所以作者主要通过比较和对比来说明身体锻炼与抑郁症之间的联系,故选B.
