19.It is common sense that children who walk or cycle to school have a lower risk of obesity than those by car.But driving your youngsters to the gates could also cause their academic work to suffer.Researchers found children who were driven to school,or who took public transport,had poorer concentration levels than those who took a more active route such as walking or cycling.
The joint study by researchers at two Danish universities found the regular exercise could advance a student up to half a year in their studies.Children who were driven to school,or who took public transport,performed less well in a test measuring concentration levels,than those who had walked or cycled.
The results surprised the researchers,as their hypothesis(假设) originally focused on the effects of eating breakfast and lunch on pupils'ability to concentrate.
"The exercise one uses to transport oneself to school is reflected in the level of concentration one has about four hours later,"Niels Egelund,a co-author of the report said."The results showed that having breakfast and lunch has an impact,but not very much compared to having exercise."
"As a third-grade pupil,if you exercise and bike to school,your ability to concentrate increases to the equivalent of someone half a year further in their studies,"he added.
In the survey,taken by 19,527 pupils aged five to 19 years old,participants were asked about their exercise habits and were then given a basic test measuring their concentration.
"Most people know the feeling of being refreshed after having exercised,but it is surprising that the effect lasts for so long,"Egelund said.
Previous research from the university of Montreal has found that exercise helps our brains make better use of oxygen.It may also reduce mental fatigue(疲劳) and sharpen your thinking in between gym sessions.And last week Swedish researchers said they found that muscular boys will live longer than their weaker friends.
And even if they are overweight by the time they get to adulthood,those with stronger muscles tend to live longer.

分析 本文是一篇科普类文章,主要讲述了研究者发现开车,坐交通工具去上学的学生和那些走路或骑车上学的学生相比,注意力不够集中,这是因为锻炼可以帮助大脑充分利用氧气,减少精神疲劳,使思维敏捷,从而使注意力更集中.
解答 51.答案:D.主旨大意题.通读全文,根据文章内容,尤其是"Researchers found children who were driven to school,or who took public transport,had poorer concentration levels than those who took a more active route such as walking or cycling"及"The joint study by researchers at two Danish universities found the regular exercise could advance a student up to half a year in their studies"可知,本文主要讲述了锻炼使学生学得更快.故选D.
52.答案:B.细节理解题.根据"Previous research from the university of Montreal has found that exercise helps our brains make better use of oxygen.It may also reduce mental fatigue(疲劳) and sharpen your thinking in between gym sessions"可知,锻炼帮助大脑充分利用氧气,减少精神疲劳,使思维敏捷,但没有提高注意力这一点.故选B.
53.答案:D.细节理解题.根据"The results showed that having breakfast and lunch has an impact"知,吃早饭和午饭会影响学生的注意力.故选D.
54.答案:C.推理判断题.根据"children who were driven to school,or who took public transport,had poorer concentration levels than those who took a more active route such as walking or cycling"可推测出,开车去上学的学生在学习方面表现得较差的原因是注意力不够集中.故选C.
