8.A recent research shows that physical activity(体育活动) may help students do better in their classes.The research comes because educators in some countries are reducing time for activities like P.E.class.Researchers go over the results of fourteen studies.Twelve were from the United States,one from Canada and one from South Africa.The studies appeared between 2009and 2013.They included more than 55,000children,aged six to eighteen.
Thomas Singh,one of the researchers,says the studies showed a relationship between physical activity and scores on subjects such as math,English and reading.Ms.Singh offers some possible explanations(解释):
"There are,first,physiological (生理的) explanations,like more blood flow,and so more oxygen (氧气) to the brain.Being physically active means there are more hormones( 荷尔蒙) produced like endorphins ( 脑内啡).And endorphins make your stress level lower and your mood improved,which means you will perform better in class.Also,students who take part in organized sports learn rules and how to follow them.This could improve their classroom behavior and help them know what they should do.
All in all,the finding tells us that physically active kids are more likely to do better in school.Ms.Singh says schools should consider the finding before they cut physical education programs.

分析 短文大意:
最近的一项研究表明,体育活动可以帮助学生在课堂上做的更好.由于一些学校削减活动课,如体育课的课时这件事导致了研究者做的这项研究.
研究人员对十四项研究的结果进行了研究.十二项来自美国,一项来自加拿大,一项来自南非.这项研究在2009年至2013年之间进行的,其中包括超过55000名年龄在六至十八的孩子.
研究者之一托马斯说,研究显示,体育活动与数学、英语和阅读等科目的成绩之间有关系.辛格女士提供了一些可能的解释:
第一,是生理上的解释,像更多的血流量,和更多的氧气输送到大脑.体育运动意味着产生更多的荷尔蒙例如脑内啡.脑内啡可使你的压力水平降低,改善你的心情.也就是说你会在课堂上表现得更好.此外,学生参加有组织的体育活动能学习规则和如何遵循他们.这可以提高他们的课堂行为,帮助他们知道他们应该做什么.
总的来说,这一发现告诉我们,身体活跃的孩子更有可能在学校做得更好.辛格女士说,学校应该在他们削减体育课程之前考虑这一发现.
解答 64:答案A.细节理解题.根据The research comes because educators in some countries are reducing time for activities like P.E.class.可知是由于一些学校削减活动课,如体育课的课时这件事导致了研究者做的这项研究.故选A.
65:答案D.细节理解题.根据Twelve were from the United States,one from Canada and one from South Africa.描述,可知有美国,加拿大和南非三个国家参与了这项研究.故选D.
66:答案C.细节理解题.根据"There are,first,physiological (生理的) explanations,like more blood flow,and so more oxygen (氧气) to the brain.Being physically active means there are more hormones( 荷尔蒙) produced like endorphins ( 脑内啡).And endorphins make your stress level lower and your mood improved,which means you will perform better in class.Also,students who take part in organized sports learn rules and how to follow them.This could improve their classroom behavior and help them know what they should do.,可知参加体育活动有助于提高血液循环速度,改善课堂行为和提高学生组织活动的能力.没有关于体育活动能让人感到放松和神清气爽的描述,故选C.
点评 本篇是一篇科普知识类阅读.这篇短文主要介绍了一项关于体育运动对学生在校表现的影响的调查报告.报告中提到了,参加体育活动有助于提高血液循环速度,改善课堂行为和提高学生组织活动的能力.因此在我们的学习生活中应注意体育锻炼.解答时应先通读一遍短文,然后带着问题再读一遍,并注意每段句首的第一句话,它们往往是本句的主旨句.
