Exercise seems to be good for the human brain，with many recent studies suggesting that regular exercise improves memory and thinking skills．But an interesting new study asks whether the apparent cognitive benefits from exercise are real or just a placebo effect — that is，if we think we will be “smarter” after exercise，do our brains respond accordingly？The answer has significant implications for any of us hoping to use exercise to keep our minds sharp throughout our lives．
While many studies suggest that exercise may have cognitive benefits，recently some scientists have begun to question whether the apparently beneficial effects of exercise on thinking might be a placebo effect．So researchers at Florida State University in Tallahassee and the University of Illinois at Urbana Champaign decided to focus on expectations，on what people anticipate that exercise will do for thinking．If people’s expectations jibe (吻合) closely with the actual benefits，then at least some of those improvements are probably a result of the placebo effect and not of exercise．
For the new study，which was published last month in PLOS One，the researchers recruited 171 people through an online survey system，they asked half of these volunteers to estimate by how much a stretching and toning regimens (拉伸运动) performed three times a week might improve various measures of thinking．The other volunteers were asked the same questions，but about a regular walking program．
In actual experiments，stretching and toning program generally have little if any impact on people’s cognitive skills．Walking，on the other hand，seems to substantially improve thinking ability．
But the survey respondents believed the opposite，estimating that the stretching and toning program would be more beneficial for the mind than walking．The estimates of benefits from walking were lower．
These data，while they do not involve any actual exercise，are good news for people who do exercise．“The results from our study suggest that the benefits of aerobic exercise are not a placebo effect,” said Cary Stothart，a graduate student in cognitive psychology at Florida State University，who led the study．
If expectations had been driving the improvements in cognition seen in studies after exercise，Mr．Stothart said，then people should have expected walking to be more beneficial for thinking than stretching．They didn’t，implying that the changes in the brain and thinking after exercise are physiologically genuine．
The findings are strong enough to suggest that exercise really does change the brain and may，in the process，improve thinking，Mr．Stothart said．That conclusion should encourage scientists to look even more closely into how，at a molecular level，exercise remodels the human brain，he said．It also should encourage the rest of us to move，since the benefits are，it seems，not imaginary，even if they are in our head．
1.Which of the following about the placebo effect is TRUE according to the passage？
A．It occurs during exercise．
B．It has cognitive benefits．
C．It is just a mental reaction．
D．It is a physiological response．
2.Why did the researchers at the two universities conduct the research？
A．To discover the placebo effect in the exercise．

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. Sometimes they wore running shoes. Other times they ran barefoot.
Researchers from the JKM Technologies Company in Virginia, the University of Virginia and the University of Colorado did the study.
They 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 study appeared in the official scientific journal of the American Academy of Physical Medicine.
The other study appeared in the journal Nature. It compared runners in the United States and Kenya. The researchers were from Harvard University in Massachusetts, Moi University in Kenya and the University of Glasgow in Scotland.
They 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 heel.
Harvard’s Daniel Lieberman led the study. He 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.
60. How many organizations are involved in the two studies?
A. Three. B. Four. C. Five. D. Six.
61. What can we learn from the text?
A. Most running shoes are designed improperly.
B. The design of high heels is better than that of running shoes.
C. No one will run with running shoes in the future.
D. Both of the studies are done in America.
62. Why do running shoes increase the risk of injuries to runners?
A. They could create stress.
B. They’re too big and heavy.
C. They can affect the way the runners land.
D. Their heels can soften landings.
63. How did the researchers do the two studies?
A. By practising. B. By comparing. C. By questioning. D. By reasoning.

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.
The study was partly supported by Vibram, which makes a kind of footwear that it says is like running barefoot. The findings have gotten a lot of attention. But the researchers say there are many problems in the way the press has reported in their paper. So they have tried to explain their findings on a Harvard Website.
