Question

    Some educators told us that more years of school could help students get higher scores on intelligence tests.That was a finding of a study of teenage males in some countries.Now，another research shows that physical activity may help students do better in their classes.

The research comes as educators in some countries are reducing time for activities like physical education.They are using the time instead for academic(学术的) subjects like math and reading.The studies appeared between 2008 and 2014.They included more than 55,000 children，aged 6 to 18.

Amika Singh：“According to the results of our study，we can conclude that being physically active is beneficial for academic performance.There are，first，Physiological explanations，like more blood flow，and so more oxygen to the brain.Being physically active means there are more hormones(荷尔蒙) produced like endorphins(内啡肽)．And endorphins make your stress level lower and your mood improved，which means you also perform better.”

Also，students taking part in organized sports learn rules and how to follow them.This could improve their classroom behavior and help them keep their mind on their work.

The study leaves some questions unanswered，however.Ms Stash says it is not possible to say whether the amount or kind of activity affected the level of academic improvement.This is because of differences among the studies.

The researchers said they found only two high­quality studies.They needed more high­quality studies to confirm(证实) their findings.They also pointed out that “results for other parts of the world may be quite different”．

Still，the general finding was that physically active kids are more likely to do better in school.Ms Singh says schools should consider that finding before they cut physical education programs.Her paper on “Physical Activity and Performance at School” is published in the Archives of Pediatric and Adolescent Medicine.

【解析】

本文是议论文。研究表明体育锻炼能提高学习成绩，呼吁学校重视体育运动。

1.细节理解题。根据第一段中Now，other research shows that physical activity may help students do better in their classes第三段中According to the results of our study，we can conclude that being physically active is beneficial for academic performance.可知研究表明，体育锻炼可能帮助学生在功课上做得更好，故选B项。

2.推理判断题。第一段Some educators told us that more years of school could help students get higher scores on intelligence tests.可知一些教育家告诉我们学习时间长能帮助学生在智力测试中得高分。最后一段Ms Singh says schools should consider that finding before they cut physical education programs.可知Ms Singh建议学校减少体育项目前考虑一下这些研究结果。由此推知一些国家的教育者认为学习对学生更重要，而不是锻炼。故选D。

3.句意猜测题。第五段提到The study leaves some questions unanswered，however．Ms．Stash says it is not possible to say whether the amount or kind of activity affected the level of academic improvement．This is because of differences among the studies可知该研究还留下了一些未解之谜。辛格女士说，无法确定是运动量还是运动类型影响到学术水平的提高。因为这些研究之间存在差异。第七段提到The researchers said they found only two highquality studies. They needed more highquality studies to confirm(证实) their findings.研究人员表示，他们只发现两项高质量研究。他们呼吁进行更多高质量研究以确认他们的发现。所以画线句子意为，世界上不同地区的结果可能大不一样，故选B项。

4.推理判断题。文章前几段说明了体育锻炼对成绩提高的好处，最后一段提到Ms．Singh says schools should consider that finding before they cut physical education programs．辛格女士说，学校应该在削减体育课之前，考虑一下这一研究发现。所以作者写本文是为了呼吁学校要认识到体育锻炼的好处，重视体育运动，故选A项。
