Question

Recently we told you about a finding that more years of school could help students get higherscores on intelligence tests．That was the finding of a study of teenage males in Norway．Now，other 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 subjects like maths and reading．The studies appeared between 2007 and 2013．They included more than 55，000 children，aged 6 to 18．

Amika Singh：“Based on 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(荷爾蒙)produced like endorphins(內(nèi)啡肽)．And endorphins make your stress level lower and? your mood improved, which means you also perform better.”

Also，students involved 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 .

Also．they were mostly observational studies．An observational study is where researchers do not do controlled comparisons．They only describe what they observe．So they might observe a link that students who are more active often have better grades．But that does not necessarily mean being active was the cause of those higher grades．

The researchers said they found only two high - quality studies．They called for more high-

quality studies to confirm their findings．They also pointed out that “outcomes 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．

1.The passage mainly tells us that ＿＿＿＿

A．a research on physical education has been done by the researchers

B．there exists a possibility that physical activity leads to higher grades

C．the amount or kind of activity directly affects academic level

D．the research shows that the children aged 6 to 1 8 don't do sports

2.Which of the following is TRUE?

A．Being mentally active is good for academic subjects．

B．The more hormones you have，the more stressed you will get．

C．They have found many high-quality studies to prove the research．

D．The educators in the research think studies，not exercise，mean much to students．

3.The underlined sentence in Paragraph 7 probably means ＿＿＿＿.

A．good marks result from high-quality study

B．findings probably vary in different areas

C．physical activity will spread all over the world

D．academic performance depends on the surroundings

4.What's the purpose of writing the passage?

A．To call our attention to the sports at school．

B．To introduce all types of physical activities．

C．To represent the academic performance．

D．To improve students' health ．

試題分析: 本文講的是體育鍛煉能提高學習成績嗎？

1.B 細節(jié)理解題。根據(jù)第一段提到Recently we told you about a finding that more years of school could help students get higherscores on intelligence tests．That was the finding of a study of teenage males in Norway．Now，other research shows that physical activity may help students do better in their classes最近我們講述了關于上學時間更長能夠幫助學生在智力測驗中得到更高分數(shù)的一項發(fā)現(xiàn)，這是針對挪威青年男子的一項研究�，F(xiàn)在其它研究表明，體育鍛煉可能幫助學生在功課上做得更好，所以選B項。

2.D 細節(jié)理解題。根據(jù)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然而該研究還留下了一些未解之謎。辛格女士說，無法確定是運動量還是運動類型影響到學術水平的提高。因為這些研究之間存在差異，所以D項正確。

3.B 細節(jié)理解題。根據(jù)第七段提到The researchers said they found only two high - quality studies．They called for more high-quality studies to confirm their findings．They also pointed out that “outcomes for other parts of the world may be quite different. 研究人員表示，他們只發(fā)現(xiàn)兩項高質(zhì)量研究。他們呼吁進行更多高質(zhì)量研究以確認他們的發(fā)現(xiàn)。他們還指出，“世界上其它地區(qū)的結果可能大不一樣，所以選B項。

4.A 細節(jié)理解題。根據(jù)最后一段提到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．盡管如此，總的結論是，喜歡運動的孩子更容易在學校表現(xiàn)更好。辛格女士說，學校應該在削減體育課之前，考慮一下這一研究發(fā)現(xiàn)，所以選A項。
