We can all contribute to a greener world．Just follow these ten golden rules:
●Stop getting junk mail．Billions of junk mail can be sent every year．Half of it is never opened．Get-your name off mailing lists．If 100,000 people stopped getting junk mail today, it would save 150,000 trees a year．
●Stop reading newspapers．All over the world, millions of newspapers are thrown away every day, 44 million newspapers in the USA alone —that"s half a million trees a week．Either recycle your newspapers or read the hews online．
●Buy clothes made from organic materials．Conventional cotton farming seriously pollutes the environment, most of which uses ch
emical pesticides （农药） and fertilizers． Organic is better!●Switch to solar energy．In one day, the sun will provide enough energy to power the planet．Why aren"t we using it?
●If you have to drive, share the ride．Most cars in the USA have only one occupant．Also, 25 percent of car rides are less than 1．5 kilometres．Get out and walk!
●Unplug your PC, TV and VCR．Simply turning them off isn"t enough．Sets left on standby are still using 25 percent of their power．
●Hold on to your balloons．Helium-filled balloons which fly away usually end up in a lake or river, where they can choke aquatic (水生的) creatures．Sav
e your balloons and use them again．Or better still, don"t use them at all．●Feed the birds．Wild birds need food, especially in v/inter when other sources can be scarce．The greater the range of foodstuffs you put out for them, the more types of birds you will attract．
●Plant a garden at your school．Learn the connection between the land and the table．Plant vegetables to eat, flowers to admire and trees to improve the air．

Critical distance apparently is present wherever and whenever there is a flight reaction. “Critical distance” includes the narrow zone separating flight distance from attack distance. A lion in a zoo will flee from an approaching man until it meets a barrier that it cannot overcome. If the man continues the approach, he soon penetrates(进入) the lion’s critical distance, at which point the cornered lion turns back and begins slowly to stalk (逼近) the man.
Social animals need to stay in touch with each other. Loss of contact with the group can be fatal(致命的) for a variety of reasons including exposure to enemies. Social distance is not simply the distance at which an animal will lose contact with his group—that is, the distance at which it can no longer see, hear, or smell the group—it is rather a psychological distance, one at which the animal apparently begins to feel anxious when it goes beyond its limits.
Social distance is not always rigidly(刻板的) fixed but is determined in part by the situation. When the young of apes and humans are mobile but not yet under control of the mother’s voice, social distance may be the length of her reach. When added control is needed because of danger, social distance shortens. To show this in man, one has only to watch a family with a number of small children holding hands as they cross a busy street.
小题1:.
Which of the following is the correct explanation of “Flight Distance” in paragraph 1?
| A．Distance between animals of the same species before fleeing. |

| D．Distance between certain animal species before fleeing. |

| B．try to hide. |
| C．begin to jump. |

| D．Spacing in Animals |
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.
小题1: What does the underlined part in Paragraph 6 mean?

| A．Parents are worried about social networks because they lead to the children’s failing grades. |
| B．Most US parents agree that the online geo-location services should be forbidden. |
| C．Most USparents will support a law that limits IT companies to using personal information. |
| D．US Congress has not yet passed any online privacy law for children and teenagers. |
