Imagine that you found a wallet in the street containing a stranger 's contact details but no cash. Would you go out of your way to return it to its owner? Now imagine that the same wallet contained a few banknotes. Would that change your response? Alain Cohn of the University of Michigan and his colleagues have taken such behavioral economics around the world.

In different countries Dr. Cohn's research assistants entered public buildings like banks, museums and police stations. They handed in a fake wallet to an employee in the reception area, saying they had found it on the street outside, before making a hurried exit. Each wallet was a see-through plastic card case containing three identical business cards with a unique email address and a fake native's name, a shopping list and a key. Most importantly, some wallets also included $13.45, while some had no cash. Then, the team simply waited to see who would email the “owner” about returning the wallet.

In 38 of the 40 countries, the wallets with money in them were returned more often than those without: 51% compared with 40% for the cashless. While rates of honesty varied greatly between different countries, the difference within individual countries between the two return rates was quite stable around 11 percentage points. In addition, wallets containing a larger sum of money ($94.15) were even more likely (by about another ten percentage points) to be returned than those with less, although the “big money” experiment was done in only three countries.

With greater temptation (诱惑), then, comes greater honesty - at least when it comes to lost wallets and small cash. Interestingly, though, when Dr. Cohn and his team surveyed a sample of 299 volunteers, most of them predicted that the more money there was in a wallet, the more likely it was that it would be kept.

A certain doubt about the motivation of others is probably good for survival, so the response of the general population may be understandable. But is the warm inner satisfaction coming from “doing the right thing” also a powerful reason? As this study shows, such thought is real and universal

1.What does Dr. Cohn's research team try to find out?

A.How long it usually takes before a lost wallet is returned.

B.How people of different occupations react to lost w alts.

C.How people behave differently at public and private places.

D.How people respond to lost wallets of varying amounts of cash.

2.What is the second paragraph mainly about?

A.Work division in the team. B.Detailed arrangements.

C.Contents inside the wallets. D.Preparations made in advance.

3.What does Dr. Cohn's research find about rates of honesty?

A.They drop with bigger money. B.They vary from country to country.

C.They are quite the same globally. D.They are stable, unrelated to money.

4.From which is the text probably taken?

A.A research paper. B.A travel brochure.

C.A psychology magazine. D.An economy newspaper.

For most people today, their GPS (Global Positioning System) has become a lifeline, giving directions to the nearest bathroom or restaurant. But the price we pay for the convenience could be our sense of direction.

“I do think GPS devices cause our navigational skills atrophy.” said Nora Newcombe, a psychologist at Temple University in the US who studies how the human brain navigates. “The problem is that you don’t see an overview of the area and where you are in relation to other things.”

To understand the risk, you first need to understand how our brain keeps us from getting lost. Through experiments, researchers have found that our navigational strategies usually fall into two groups. The first involves a spatial map inside your brain. As you explore an area, you think about how the streets fit together and the best way to get between different places. Eventually, the map lets you navigate between any two points in the area. The second involves a series of landmarks and steps: turn right at the gas station, and your school is on the left. It’s quick and reliable, but less flexible—it doesn’t help you get from your school to a totally new place, even if it’s nearby.

These two methods might not sound all that different, but according to Nora Newcombe, a psychologist at Temple University in the US, people who are bad at navigation have trouble with the first strategy – creating spatial maps. What’s more, people’s ability to create maps is decided by how often we use the skill.

That helps explain what happens when people trust themselves with GPS devices. According to Professor Veronique Bohbot of McGill University, people depending on GPS show more activity in the part of the brain that is good at following directions—but less activity in the part which creates the spatial maps.

It turns out that our sense of direction isn’t the only thing we could lose. One more thing that could go is our connection to the environment we travel through. Researchers have found that when people rely on GPS while driving, their memory of their trip is of a route on a screen, rather than the landscape they traveled through. Moreover, researchers believe that active navigation improves the type of thinking used in all kinds of spatial processes. “It’s things like urban planning, and looking at a map to see where resources are. That’s not replaceable by your phone.” Newcombe said.

1.______is what we may lose for the convenience of using GPS.

A.The ability to read maps B.The sense of feeling the sun

C.The chance to do urban planning D.The connection to where we travel

2.The underlined word “atrophy” in Paragraph 2 is closest in meaning to______.

A.become weaker B.become stronger

C.become more useful D.become less important

3.What may be Veronique Bohbot’s purpose in his research?

A.To explain why people use navigation

B.To prove what happens when we use GPS devices.

C.To find out people’s ability to create the spatial maps.

D.To tell the differences between the first strategy and the second direction.

4.What may be the writer’s attitude towards people relying on GPS devices?

A.Objective B.Ambiguous C.Negative D.Indifferent

Cells in our brain usually send “stop eating” signal when we’ve had enough. But after mice ate fatty foods for just two weeks, their brains’ brake on overeating quieted down. That finding may help explain the complex link between food and appetite that can become disordered when people overeat.

Food is essential to life. Our brains have, therefore, evolved a series of systems to make sure we eat enough. Garret Stuber, a neuroscientist at the University of Washington, together with his team took aim at one brain area known to be involved in eating behaviors.

This lateral hypothalamus (下丘脑外侧区) contains many diverse cells Stuber’s group looked at the behaviors of genes in the cells here. And in one type—glutamatergic nerve (谷氨酸能神经) cells—big differences appear between fat mice and lean ones.

Earlier work by Stuber’s group had suggested that these cells act like a brake on eating. When the researchers prevented these cells from firing, mice suddenly overate. They also fattened up. But it wasn’t clear how the cells’ activity changed as the mice transitioned from slim to fat.

“Obesity doesn’t just happen overnight,” notes Stuber. To find out the secret, his group undertook a new study. They fed mice high-fat food. Now and again, they’d use a fancy microscope to look at how well the animals’ glutamatergic cells could fire off signals.

Two weeks into the high-fat food—even before the mice became round – the activity of these nerve cells had slowed. It continued as the animals grew larger over a 12-week period. “The cells’ activity was going down as a function of high-fat diet. The results suggest that the high-fat diet is removing the brake on eating and obesity,” explains Stuber.

It’s hard to say whether similar cells normally control people’s appetite. Brain-imaging tests have shown that the same brain region —the hypothalamus—plays a role when people shift between hunger and feeling full.

1.What happened after the mice ate fatty foods for two weeks?

A.Their appetite was getting worse. B.Their brains became disordered.

C.They refused to eat zero fat food. D.They lacked a feeling of fullness.

2.It can be learned from the text that glutamatergic nerve cells ________.

A.are easily found in lean mice B.can prevent mice from overeating

C.function well under any condition D.are a main part of lateral hypothalamus

3.Why did Stuber’s group undertake the new study?

A.To study the role of glutamatergic cells in mice’s fattening up.

B.To find out the link between high-fat diets and obesity.

C.To find out deciding factors in mice’s appetite.

D.To study the eating habit of fat mice.

4.What is the main idea of the text?

A.Obesity influences glutamatergic nerves’ function.

B.Glutamatergic nerves decide people’s appetite.

C.High-fat diets lead to overeating.

D.Our brains control our food choices.
