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."

分析 本文主要向讀者介紹了一項科學(xué)研究成果,這項研究主要介紹了身體鍛煉與抑郁癥之間的聯(lián)系.研究表明,增加每周鍛煉身體的次數(shù),能降低人們患抑郁癥的風(fēng)險.
解答 25.B 寫作意圖題.本文主要向讀者介紹了一項科學(xué)研究成果,這項研究主要介紹了身體鍛煉與抑郁癥之間的聯(lián)系,故選B.
26.A 細(xì)節(jié)理解題.根據(jù)第二段的People who increased their weekly activity reportedfewer depressive symptoms but those with more depressive symptoms were lessactive可知,增加每周活動的人報告說有較少的抑郁癥狀,但那些有更多的抑郁癥狀的是較不活躍的,特別是在年輕的年齡.所以如果人們增加每周鍛煉身體的次數(shù),就會有較少的抑郁癥狀,故選A.
27.D 細(xì)節(jié)理解題.根據(jù)第一段的Being physically active three times a week reducesthe odds of being depressed by about 16%可知,每周鍛煉三次,大約降低16%患抑郁癥的可能性.所以增加每周鍛煉身體的次數(shù),在某種程度上能降低人們患抑郁癥的可能性,故選D.
28.B 推理判斷題.根據(jù)全文尤其是根據(jù)第三、四段的內(nèi)容可知,研究人員記錄了出生于1958的11135人直到50歲,在成年期定期記錄抑郁癥狀和身體活動水平.他們發(fā)現(xiàn)每周增加活動期間減少抑郁癥的幾率為6%.如果一個在二十多歲和四十多歲不太活動的成年人變?yōu)槊恐芑顒?次,他們會減少約16%的抑郁癥風(fēng)險.所以作者主要通過比較和對比來說明身體鍛煉與抑郁癥之間的聯(lián)系,故選B.
點評 本文是科教類閱讀,主要考查細(xì)節(jié)理解題和推理判斷題.在做細(xì)節(jié)理解題時,首先根據(jù)題目要求迅速在文章里找出相應(yīng)的段落、句子或短語.認(rèn)真比較選項和文中細(xì)節(jié)的區(qū)別,在做推理判斷題時不要以個人的主觀想象代替文章的事實,要根據(jù)文章事實進(jìn)行合乎邏輯的推理判斷.
