Walking to Exercise the Brain
Do you think sitting and studying all the time will improve your grades?Think again?Getting some exer-
cise may help,too.
New research with old people suggests that taking regular walks helps them pay attention better than if
they didn't exercise.
Previous research had shown that mice learn,remember,and pay attention better after a few weeks of
working out on a running wheel.Mice that exercise have greater bl0od flow to the brain than those who don't.
Their brain cells also make more connections.
Neuroscientists（神经科学家）from the University of Illinois at Urbana-Champaign wanted to find out if
the same thing is true for people.First,they measured the physical fitness of 41 adults,ages 58 to 77,after
each person walked 1 mile.Then,participants looked at arrows on a computer screen and had to use computer
keys to show which way one particular arrow was pointing.
Adults who were physically fit were faster at the arrow task,and their answers were just as accurate as
their less-it peers,the researchers found.The fitter participants also had more blood flow to a part of their
brain responsible for paying attention and making decisions.
In a second study , 15 elderly people who completed a 6-month aerobic-training（有氧运动）course were
faster at attention tasks compared with 14 seniors who just did stretching and toning exercises（韵律操）for
the same amount of time.
So,even going for a walk every 2 or 3 days for just 10 to 45 minutes can help.That should be good news
for the elderly.
The effects of exercising on the brains of younger people haven't been studied yet.Still,it can't hurt to
take occasional breaks and' go for a walk or run around with friends.Whatever you do,though,don't try to
read and walk at the same time.You could end up hurting yourself! After taking exercise for a few weeks,the mice were found to have__________.A:higher blood pressureB:faster heartbeatC:more blood flow to the brainD:better appearance

材料
运动会结束后，小华在周记中写下了自己的感受：
这一次学校秋季运动会非比寻常，因为有一个特殊的项目，那就是班级的韵律操比赛。我们班余老师是一位比较要强的老师，听同学们讲，每次比赛，她都力争好成绩。
大家熟悉的班级韵律操对我这个刚转来的新手来说，可以说是难上加难。有班干部向余老师建议，不让我参加比赛。我本想余老师会同意，反正学校并没有要求必须全班参加，再说我刚刚转来。但是余老师没有同意，在班上说：“咱们是一个团队，是一个整体，班上一个同学都不能少！”我感觉余老师用鼓励的眼光看着我。
眼见比赛日益临近，我很是着急，看得出与我们一同训练的余老师也很着急，余老师找到我，一边鼓励我一定行，一边亲自手把手教我韵律操的每一个动作。
余老师腰不好，我看到余老师每次讲解示范动作弯腰时，总咬着牙，我更是认真地操练。在余老师的帮助下，我终于在较短的时间内学会了班级的韵律操。
请评析余老师的教育行为。
