3．Two new studies suggest that modern running shoes could increase the risk of injuries to runners．
One study involved sixty-eight healthy young women and men who ran at least twenty-four kilometers a week．The runners were observed on a treadmill machine（跑步机）．Sometimes they wore running shoes．Other times they ran barefoot．
Researchers found that running shoes create more stress that could damage knees，hips and ankle joints than running barefoot．They observed that the effect was even greater than the effect reported earlier for walking in high heels．
The other study compared runners in the United States and Kenya．The researchers divided the runners into three groups．One group had always run shoeless．Another group had always run with shoes．And the third group had changed to shoeless running．
Runners who wear shoes usually come down heel first．That puts great force on the back of the foot．But the study found that barefoot runners generally land on the front or middle of their foot．That way they ease into their landing and avoid striking their heels．
Daniel Lieberman says the way most running shoes are designed may explain why those who wear them land on their heels．The heel of the shoe is bigger and heavier than other parts of the shoe，so it would seem more likely to come down first．Also，the heel generally has thick material under it to soften landings．
But the researchers do not suggest that runners immediately start running barefoot．They say it takes some training．And there can be risks，like running when your feet are too cold to feel if you get injured．
24．What's the main idea of the passage？D
A．Running in shoes is partly good to runners．
B．Two new discoveries encourage people to run in high heels．
C．Walking in high heels could cause less serious effects than running barefoot．
D．Two new studies prove running without shoes is beneficial to runners in most cases．
25．From the fifth paragraph we can infer thatB．
A．running barefoot is faster than running in shoes．
B．the landing point is very important in running．
C．running shoeless can give people a real exercise．
D．different running ways cause different injuries．
26．Why do people who run in shoes land on their heels？B
A．Because the shoes put great force on the back of the foot．
B．Because the design of running shoes is unreasonable．
C．Because people who often run get used to landing on their heels．
D．Because the running people want to run faster．
27．What's the writer's attitude towards the use of the modern running shoes？C
A．Positive．
B．Persuasive．
C．Objective．
D．Supportive． 试题答案
分析 文章主要阐述了两项研究的结果．两项新的研究显示，穿跑鞋对运动员的伤害会很大，而赤脚跑步能够减轻对膝盖、脚踝等的伤害．
解答 24-27．DBBC
24题答案：D考查主旨大意，文章主要阐述了两项研究的结果．两项新的研究显示，穿跑鞋对运动员的伤害会很大，而赤脚跑步能够减轻对膝盖、脚踝等的伤害．故本题答案为D选项．
25题答案：B考查细节推理，文章第五段讲的是穿鞋跑着地时是后跟先着地，这样的话大量脚的后部的力量就很大；而裸脚跑是脚的前部或中部先着地，这样的话他们是以缓冲的方式着地而且避免了脚后跟的受伤．可知"落点很重要"，故本题答案为B选项．
26题答案：B考查细节推理，根据文章倒数第二段的Daniel Lieberman says the way most running shoes are designed may explain why those who wear them land on their heels．Daniel Lieberman 说大多数鞋子设计的方式有可能解释了为什么那些穿它们的人会以脚后跟着地．由此可知脚后跟着地的原因是因为设计不合理，故本题答案为B选项．
27题答案：C考查情感态度，两项新的研究都显示穿跑鞋对运动员的伤害会很大，而赤脚跑步能够减轻对膝盖、脚踝等的伤害；因此作者是反对穿鞋跑步的．故本题答案为C选项．
点评 本文是一篇科教类阅读，题目涉及多道细节理解题，做题时结合原文和题目有针对 性找出相关语句进行仔细分析，结合选项选出正确答案．推理判断也是要在抓住关键句子的基础上合理的分析才能得出正确的答案．
Fear may be felt in the heart as well as in the head，according to a study that has found a link between the cycles of a beating heart and the chance of someone feeling fear.
Tests on healthy volunteers found that they were more likely to feel a sense of fear at the moment when their hearts are contracting and pumping blood around their bodies, compared with the point when the heartbeat is relaxed. Scientists say the results suggest that the heart is able to influence how the brain responds to a fearful event, depending on which point it is at in its regular cycle of contraction and relaxation.
Sarah Garfinkel at the Brighton and Sussex Medical School said：“Our study shows for the first time that the way in which we deal with fear is different depending on when we see fearful pictures in relation to our heart.”
The study tested 20 healthy volunteers on their reactions to fear as they were shown pictures of fearful faces. Dr Garfinkel said, “The study showed that fearful faces are better noticed when the heart is pumping than when it is relaxed.Thus, our hearts can also affect what we see and what we don't see—and guide whether we see fear.”
To further understand this relationship，the scientists also used a brain scanner(扫描仪)to show how the brain influences the way the heart changes a person's feeling of fear.
“We have found an important mechanism by which the heart and brain ‘speak’ to each other to change our feelings and reduce fear,”Dr Garfinkel said.
“We hope that by increasing our understanding about how fear is dealt with and ways that it could be reduced, we may be able to develop more successful treatments for anxiety disorders，and also for those who may be suffering from serious stress disorder.”
