A picture of a set of eyes on a computer screen can cause a change in the way people act. Even images of eyes on a charity donation, collection box encourage people to be unselfish, because people put more money in a
collection box that has a picture of eyes on it than they do when a flower symbol is on the box.
Manfred Milinski from the Max-Planck Institute for Evolutionary Biology in Germany and Bettina Rockenbach of the University of Berlin, the authors of a new study, found that people act better when they are being watched because they feel they will be rewarded for good behavior. Their report also referred to other research showing that this response of behaving well when watched is somehow coded into humans and people respond this way unconsciously, or without realizing it.
It is not just humans that act unselfishly when they are being watched. A fish called the grooming fish cleans other fish. When other fish are around, it is gentler. When no other fish are around, however, the grooming fish bites chunks from the fish it is supposed to be cleaning.
The researchers suggest that the best way to get people to behave in the correct way is to make them feel watched. This could be the reason for the success of a famous American army poster. On it was a picture of an elderly man staring fiercely and pointing, it appeared, to the person who was looking at the poster. Under the picture was the caption "I Want You" It encouraged hundreds of thousands of young American men to join the army during the Second World War to fight the Germans and Japanese.

“It’s the next ‘wow’ vehicle，”said Terrafugia vice president Richard Gersh .“Anybody can buy a Ferrari, but as we say, Ferraris don’t fly.”
The car plane has wings that unfold for flying—a process the company says takes one minute—and fold back up for driving. A runway is still required to take off and land.
The Transition is being marketed more as a plane that drives than a car that flies, although it is both. The company has been working with FAA to meet aircraft regulations, and with the National Highway Traffic Safety Administration to meet vehicle safety regulations.
The company is aiming to sell the Transition to private pilots as a more convenient and cheaper way to fly. They say it saves you the trouble from trying to find another mode of transportation to get to and from airports: You drive the car to the airport and then you’re good to go. When you land, you fold up the wings and hit the road. There are no expensive parking fees because you don’t have to store it at an airport—you park it in the garage at home.
The car-plane is designed to fly primarily under 10,000 feet. It has a maximum takeoff weight of 1,430 pounds, including fuel and passengers. Terrafugia says the Transition reduces the potential for an accident by allowing pilots to drive under bad weather instead of flying into marginal(临界)conditions.
The Transition’s price tag: $194,000, But there may be additional charges for options like a radio, transponder or GPS. Another option is a full-plane parachute.
“If you get into a very awful situation, it is the necessary safety option,” Gersh said.
So far, the company has more than 70 orders with deposits.“We’re working very closely with them, but there are still some remaining steps,” Brown said.

40 Nanjing has shown a remarkable capacity for reinvention during its 2,500-year history. And in recent years, the city has moved 41 its tragic past to become a vital engine of China’s economic growth, thanks 42 to its position in the middle of China’s prosperous eastern seaboard. Growth has also 43 thanks to improved ground transportation: A new bullet train linking Nanjing and Shanghai started service last year, 44 travel time between the cities from several hours to just 75 minutes, and a Beijing-Shanghai high-speed line is 45 to open later this year, with a stop in Nanjing. Within the city, two metro lines were built in the last few years; 15 more are planned to begin service by 2030.
Signs of Nanjing’s 46 wealth and optimism can be seen everywhere. In the heart of the downtown Xinjiekou district, a bronze statue of Sun Yat-sen, 47 the father of modern China, looks 48 over a busy 49 area.
There is perhaps no more 50 symbol of the city’s transformation than the Zifeng Tower, a 1,480-foot skyscraper that opened its doors last May. 51 offices, restaurants and an InterContinental hotel, the tower is the second-tallest building in China and billed as the seventh-tallest in the world.
Underlying all this development is a large Chinese and 52 student population — there are several major universities, plus a branch of Johns Hopkins’s international studies school. In fact, art and music 53 in all sorts of places.
On a larger 54 , local government officials and private investors are pushing the city as a rising center for contemporary art and architecture, hoping to attract 55 from the neon-bathed streets of its neighbor Shanghai.

The survey was conducted for Common Sense Media, a nonprofit organization devoted to helping families find the right way to deal withthe world of media and technology.
Ninety-two percent of parents said they are concerned that children share too much information online, and 85 percent said they are more concerned about online privacy than they were five years ago. In other findings, Common Sense Media found that 68% of parents are not at all confident in search engines keeping their private information safe and secure and 71% of parents said the same about social networking sites.
The survey found a great deal of concern about the online geo-location
services which find and show the exact position of somebody through the net. Ninety-one percent of parents said search engines and social networking sites should not be able to share the physical location of children with other companies unless the parents approve.“The survey results present a clear divide between the industry’s view of privacy and the opinion of parents and kids,” Common Sense Media CEO and founder James Steyer said.
“American families are deeply worried about how their personal information is being used by technology and online companies, yet the companies appear to be keeping their heads deep in the sand,” Steyer said.
IT companies need to step up but parents, children, schools and government also need to do more, he said.
“Parents and kids have to educate themselves about how to protect their information,” he said. “Schools should teach all students and their parents about privacy protection.”
“And finally, policymakers have to update privacy policies for the 21st century,” he said. According to the survey, more than 60 percent of parents want the US Congress to update online privacy laws for children and teenagers.

A study of Gentral American leaf-cutter ants has shown that the younger and stronger members are give the toughest job of cutting therough the leaves they harvest.Their sharp youn teeth do this job effectively,but as they get older their teeth become relatively worn and blunt.
But rather than being retired or abandoned by the group,the ageing ants are given a new role more suyted to their physical abilities.They become carriers and teansport the leaves back to the kingdom where they are harvested for food.
The findings by researchers from the University of Oregon and the Oregong State University support previous research showin the survival of a leaf-cutter kingdom depends on the efficiency(效率）of is workers.
“Cuting leaves is hard work,”said Dr.Robert Schofield,who led the research team.“Much of the cutting is done with a V-shaped blade(刀片）between teeth on their jaws.This blade starts out as sharp as the sharpest razor blade that humans have developed.”But over rime the teeth become blunter and the cutting job slows down.The team estimated that,because of this age-related wear,a colony(蚁群)spent twice the energy cutting leaves than it would if all the ants had sharp blades.Its findings support the idea that wear and break can be significant problems for insects as well as largre animals.
Like humans,leaf-cuttre ant recognize that older members of the group can still make a worhwhile contribution to society.“This study shows an advantage of social living that we are familiar with,”said Dr.Schofield.

| C．They have to leave and live on themselves. |
| D．They are given a new worthwhile job. |
| A．Dr.Schofield is the first to research leaf-cuttre ants |
| B．older ants are more powerful in carrying leaves |
| C．large animals can also suffer from some kind of wear |
| D．leaf-cutter ants are the most lever ants in the world |

Spending time with grandma and grandpa especially appears to help children from single-parent, divorced/separated or stepfamily households, according to the report, published in the February Journal of Family Psychology.
"Grandparents are a positive force for all families but play a significant role in families undergoing difficulties," the study"s lead author, Shalhevet Attar-Schwartz, of The Hebrew University of Jerusalem, said in an American Psychological Association news release. "They can reduce the negative influence of parents separating and be a resource for children who are going through these family changes."
In interviewing 11- to 16-year olds from England and Wales, Attar-Schwartz and her team found that the more conversations the youths had with a grandparent, including asking for advice or even money, the better they got along with their peers and the fewer problems they had, such as hyperactivity and disruptive behavior.
"This was found across all three family structures," she said. "But adolescents in single-parent households and stepfamilies benefited the most. The effect of their grandparents" involvement was stronger compared to children from two biological parent families."
The study did not look at children who lived solely with their grandparents, though.
The findings have great implications for people in the United States, the authors said, because American grandparents are increasingly sharing living space with their grandchildren. A 2004 U.S. Census Bureau survey found that more than 5 million households include a grandparent and a grandchild under 18, up 30 percent since 1990, according to background information in the news release.
小题1:It is generally believed that a grandmother __________ .
| A．can help a child through hard times |

| B．from a single—parent household |
| C．from a divorced household |
| D．from a stepfamily household |
| A．have difficulty in getting along with his peers |
| B．still get along well with his peers |
| C．be easier to be spoiled than his peers |
| D．not be popular with peers |
| A．there are more families in America undergoing difficulties |
| B．American parents are much busier than those from other countries |
| C．American grandparents are much better at bringing up their grandchildren |
| D．American kids like to share more living space with their grandparents |
| A．children who live solely with their grandparents may benefit the most |
| B．grandparents are a source of comfort to children from families undergoing difficulties |
| C．grandparents play a more positive role than parents in children’s growth |
