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．

B．To prove the previous studies have a big drawback．

C．To test whether exercise can really improve cognition．

D．To encourage more scientists to get involved in the research．

3.What can we know about the research Cary Stothart and his team carried out？

A．They employed 171 people to take part in the actual exercise．

B．The result of the research removed the recent doubt of some scientists．

C．The participants thought walking had a greater impact on thinking ability．

D．Their conclusion drives scientists to do research on the placebo effect．

4.What might be the best title for the passage？

A．Is it necessary for us to take exercise？

Your chair is your enemy. That is the conclusion of several recent studies. Among people who sit in front of the television for more than three hours each day, those who exercise are as fat as those who don’t.

So what’s wrong with sitting? The answer seems to have two parts. The first is that sitting is one of the most passive things you can do. Compared to sitting, standing in one place is hard work. To stand, you have to tense your leg muscles, and engage the muscles of your back and shoulders; while standing, you often shift from leg to leg. All of this burns energy.

You may think you have no choice about how much you sit. But this isn’t true. Suppose you sleep for eight hours each day, and exercise for one. That still leaves 15 hours of activities. Even if you exercise, most of the energy you burn will be burnt during these 15 hours, so weight gain is often the cumulative(累积的) effect of a series of small decisions: Do you take the stairs or the elevator? Do you walk to the corner store, or drive?

But it looks as though there’s a more sinister aspect to sitting. Some evidence suggests that when you spend long periods sitting, your body actually does things that are bad for you.

Lipoprotein lipase(蛋白脂酶) is a molecule that plays a central role in how the body processes fats. Low levels of lipoprotein lipase are associated with a variety of health problems. Studies in rats show that leg muscles only produce this molecule when they are actively being moved. The result is that when you sit, an important part of your metabolism(新陈代谢) slows down. You may also have a higher risk of suffering from diabetes(糖尿病).

Some people have advanced radical solutions to the sitting syndrome(综合症): replace your sit-down desk with a stand-up desk, or watch television in a rocking chair. But whatever you choose, know this. The data is clear; look out for your chair.

1.What would be the best title of this passage?

A．Become an Athlete to Be Healthy.

B．Choose a Better Chair for You.

C．How to Speed Up Your Metabolism.

D．Stand Up While You Read This.

2.Paragraphs 2 and 3 tell us that.

A．taking too much exercise harms people’s health

B．sitting a lot reduces the benefits of taking exercise

C．people needn’t depend on exercise to keep healthy

D．healthy people are those who sit less and stand more

3.Which of the following is the best advice on how to control our weight?

A．Exercising at least an hour a day.

B．Standing as long as possible.

C．Using our energy actively in daily life.

D．watching TV in a rocking chair.

4.The author mentions lipoprotein lipase mainly to.

A．show that it plays a big part in keeping us healthy

B．tell us that it isn’t produced while we are sitting

C．suggest that we should take less exercise to be healthy

D．prove sitting for long is bad for our body

Recently a study, led by Pedro Hallal of the Federal University, suggests that nearly a third of adults, 31%, are not getting enough exercise. That rates of exercise have declined is hardly a new discovery. Since the beginning of the industrial revolution, technology and economic growth have helped to create a world in which taking exercise is more and more an option rather than a necessity. But only recently have enough good data been collected from enough places to carry out the sort of analysis Dr Hallal and his colleagues have engaged in.

There are common themes in different places. Unsurprisingly, people in rich countries are less active than those in poor ones, and old people are less active than young ones. Less obviously, women tend to exercise less than men—34% are inactive, compared with 28% of men. But there are exceptions. The women of Croatia, Finland, Iraq and Luxembourg, for example, move more than their male countrymen.

Malta wins the race for most slothful country, with 72% of adults getting too little exercise, and Swaziland and Saudi Arabia are in close behind, with 69%. In Bangladesh, just 5% of adults fail to exercise enough. Surprisingly, six Americans in ten are active enough according to Dr Hallal’s study, compared with fewer than four in ten British.

These high rates of inactivity are worrying. Human beings seem to have evolved(进化) to benefit from exercise while deliberately avoiding it whenever they can. In a state of nature it would be impossible to live a life that did not provide enough of it. But that is no longer the case. Actually lack of enough activity these days has nearly the same effect on life span(寿命) as smoking.

1.We may learn from Paragraph 1 that_________.

A. the decline of exercise rates is newly discovered

B. the study suggests 31% of female adults get too little exercise

C. the good enough data has been collected from only one country

D. the industrial revolution has changed the way people live to some degree

2.According to the study, women of Luxembourg_________.　

A. have little time to exercise

B. hate to get regular exercise

C. take more exercise to lose weight

D. exercise more than men in their country

3.The underlined word “slothful” in Paragraph 3 most probably means_________.

A. powerful　　　　　　　　　 　　　　　　　　　 　　　　　　　　　 B. rich　　　　　　　　　 　　　　　　　　　 　　　　　　　　　 C. lazy　　　　　　　　　 　　　　　　　　　 　　　　　　　　　 D. unpopular
