The study, published in JAMA Psychiatry, found a two-way relationship between depression and physical activity. People who increased their weekly activity were reported to have 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 his twenties and forties who isnt physically active became active 3 times per week, he would reduce his risks of depression by about 16%，” said Dr Snehal of the UCL Institute of Child Health, lead author of the study. Professor Mark, Director of the Public Health Research Centre, said: “Many people are already aware of the benefits of physical activity on their general health, but now we are seeing more evidence that suggests it also has a positive effect on a persons 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.” 文章大意：必威体育精装版研究表明，增加每周锻炼身体的次数，能降低人们患上抑郁症的风险。 1．The underlined word “odds” in Paragraph 1 probably means “________”． A．benefits　　　　　　　　　　 B．intervals C．risks D．ages 答案：C　词义猜测题。根据第四段中的“If an adult between his twenties and forties who isnt physically active b
