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! It can be good for health when one takes a walk every 2 or 3 days for at least__________.A:3 minutesB:45 minutesC:30 minutesD:10 minutes

二、考题解析【教学过程】(一)开始部分1.课堂常规：体委整队，报告人数，师生问好，教师简要介绍教学内容，检查服装，安排见习生。导入：今天我们首先看一段视频，大家看到里面讲的内容是什么?看完同学们告诉老师看到了谁?对，同学们看到的是我国在大阅兵时候的一段视频，视频中队伍的变化多种多样，大家看到后都很兴奋。那我们也一起来感受一下吧，今天我们就来学习队列队形中的分队走和合队走。(二)准备部分1.图形跑方法：全班同学成一路纵队，教师领跑，在跑的过程中变换不同的图形，如：三角形、圆形、正方形等，同时教师需要通过语言调动学生的积极性。组织教学：在课前画好的区域内进行。2.配乐韵律操开合运动、踢腿运动、侧展运动、体转运动、跳跃运动。组织教学：四列横队体操队形，教师边做示范，边提示动作要领，语言激励学生，及时表扬鼓励。要求：拍节准确，动作到位，节奏感强。(三)基本部分1.示范提问：大家观察示范小组在分队走和合队走的过程中变换形式是怎样的?学生回答：分队走由一队分成了两队，合队走由两队合成了一队。组织教学：四列横队，前两排蹲下。2.讲解一路纵队中场行进，听到分队走的口令第一名同学左转弯，第二名同学右转弯，后面同学依次跟进，成二路纵队沿左右边线绕场进行。即将相遇，听到合队走的口令时，左路同学左转弯，右路同学右转弯并依次插入左路学生之后，成一路纵队进行。3.练习(1)分队走练习。将学生一路纵队在中场依次排开，根据老师口令进行分队走练习。(教师喊“齐步—走”的时候学生开始向前行进，当教师喊到“分队—走”的时候，学生按要求分成两队进行分队走练习。)(2)合队走练习。将学生分为两组在场地两边排开，根据老师口令进行合队走练习。(教师下达“齐步—走”的时候学生开始向前行进，当走至面对面时，教师下达“合队—走”口令，学生按要求合成一队进行合队走练习。)4.优生展示：教师选出优生进行展示师生进行自评、互评。(四)结束部分1.放松活动—配乐放松操组织教学：四列横队体操队形。要求：放松活动，身心充分放松。2.课堂小结：教师总结学练情况，表扬先进，激励全体学生。3.宣布下课、师生再见、回收器材。【答辩题目解析】1.本节课的重难点是什么?2.如何对队形队列进行教学计划的设计?

材料：运动会结束后小华在周记中写下自己感受：  这次学校秋季运动会非比寻常，因为有个特殊项目，那就是班级韵律操比赛。  我们班余老师是个比较要强的老师，听同学们讲，每次比赛她都力争好成绩。大家熟练的班级韵律操对我这个刚转来的新手来说，可以说难上加难。有班干部向余老师建议不让我参加比赛，我想余老师会同意，反正学校并没有要求全班参加，再说我刚刚转来，但余老师没同意，在班上说我们是个团队，是个整体，班上的个同学都不能少。我感觉到余老师用鼓励的眼光看着我。  眼见比赛日渐临近，我很是着急，看得出来我们一同训练的余老师也很是着急，余老师找到我，一边鼓励我一定能行，一边亲自手把手教我韵律操每一个动作。余老师腰不好，我看到余老师每次讲解动作弯腰时，总是咬着牙，我更是认真的操练。在老师的帮助下，我终于在较短的时间内学会了班级韵律操。  比赛终于来了，临赛前余老师走过来，笑着对我们说：同学们，不要太看重比赛成绩，只要将我们平时操练的水平展现出来就可以了说完还朝我点头微笑，我知道余老师为什么朝我点头微笑，那是在鼓励我，相信我能行。随着音乐声起，我按照余老师平时教我的韵律操动作，一丝不苟做着，同学们也异常认真。功夫不负有心人，在大家齐心协力努力下，我们班终于夺得冠军。问题：请结合材料，从教师职业道德角度，评析余老师的教育行为（14分）
