Researchers found that people become happier and experience less worry after they reach the age of fifty. In fact, they say by the age of eighty-five, people are happier with their life than they were when they were eighteen years old.
Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study. His team found that levels of stress were highest among adults between the ages of twenty-two and twenty-five. The findings showed that stress levels dropped sharply after people reached their fifties. Happiness was highest among the youngest adults and those in their early seventies. The people least likely to report feeling negative emotions were those in their seventies and eighties.
The findings appeared in the Proceedings of the National Academy of Sciences. Researchers say they do not know why happiness increases as people get older. One theory is that, as people grow older, they grow more thankful for what they have and have better control of their emotions. They also spend less time thinking about bad experiences.
The researchers considered possible influences like having young children, being unemployed or being single. But they found that influences like these did not affect the levels of happiness and well-being related to age.
The study also showed that men and women have similar emotional patterns as they grow older. However, women at all ages reported more sadness, stress and worry than men.

Waste can be seen everywhere in the school. Some students ask for more food than they can eat and others often forget to turn off the lights when they leave the classroom. They say they can afford these things. But I don’t agree with them.
Waste can bring a lot of problems. Although China is rich in some resources(资源), we are short of(缺乏) others, for example, fresh water(淡水). It is reported that we will have no coal(煤) or oil to use in 100 years. So if we go on wasting our resources, what can we use in the future and where can we move? Think about it. I think we should say no to the students who waste things every day. Everybody should stop wasting as soon as possible.
In our everyday life, we can do many things to prevent waste from happening, for example, turn off the water taps(水龙头) when we finish washing, turn off the lights when we leave the classroom, try not to order more food than we need, and so on. Little by little, everything will be changed. Waste can be stopped one day, if we do our best.
【小题1】From the passage we know that some students often _______ in the school.
| A．eat too much | B．don’t work hard | C．waste things | D．throw rubbish everywhere |
| A．Fresh water. | B．Forest. | C．Oil. | D．Coal. |
| A．We may still have enough oil. | B．We may still have enough coal. |
| C．We may have a little oil. | D．We may have no coal or oil to use. |
| A．Stop Wasting | B．School life |
| C．Waste in the School | D．Rich Resources in China |

The common cold is the world's most widespread illness, which is plagues(疫病) that flesh receives.
The most widespread mistake of all is that colds are caused by cold. They are not. They are caused by viruses(病毒) passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated Arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.?
During the First World War soldiers who spent long periods in the trenches(战壕), cold and wet, showed no increased tendency to catch colds.?
In the Second World War prisoners at the notorious Auschwitz concentration camp(奥斯维辛集中营), naked and starving, were astonished to find that they seldom had colds.?
At the Common Cold Research Unit in England, volunteers took part in Experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in drafty room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.?
If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter? Despite the most pains—taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on.?
No one has yet found a cure for the cold. There are drugs and pain suppressors(止痛片) such as aspirin, but all they do is to relieve the symptoms(症状).
【小题1】The writer offered _______ examples to support his argument.
| A．4 | B．5 | C．6 | D．3 |
| A．The Eskimos do not suffer from colds all the time. |
| B．Colds are not caused by cold. |
| C．People suffer from colds just because they like to stay indoors. |
| D．A person may catch a cold by touching someone who already had one. |
| A．they are working in the isolated Arctic regions |
| B．they are writing reports in terribly cold weather |
| C．they are free from work in the isolated Arctic regions |
| D．they are coming into touch again with the outside world |
| A．the fallacy about the common cold |
| B．the experiments on the common cold |
| C．the reason and the way people catch colds |
| D．the continued spread of common colds |

What makes a person a scientist？Does he have ways or tools of learning that are different from those of others？The answer is “no”. It isn’t the tools a scientist uses but how he uses these tools which make him a scientist. You will probably agree that knowing how to use a power is important to a carpenter(木匠).You will probably agree，too，that knowing how to investigate(调查)，how to discover information，is important to everyone. The scientist，however，goes one step further；he must be sure that he has a reasonable answer to his questions and that his answer he gets to many questions is into a large set of ideas about how the world works.?
The scientist’s knowledge must be exact. There’s no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one time must work under the same conditions at other times. If the conditions are different，any changes the scientist observes in a demonstration(实证)must be explained by the changes in the conditions. This is one reason why investigations are important in science. Albert Einstein，who developed the Theory of Relativity，arrived at this theory through mathematics. The accuracy(正确性)of his mathematics was later tested through investigation. Einstein’s ideas were proved to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations(计算)that may test his investigations.
【小题1】What makes a scientist according to the passage？
| A．The tools he uses. | B．His ways of learning. |
| C．The way he uses his tools. | D．The various tools he uses. |
| A．the importance of information |
| B．the difference between scientists and ordinary people |
| C．the importance of thinking |
| D．the difference between carpenters and ordinary people |
| A．works under one set of conditions at one time and also works under the same conditions at other times |
| B．doesn’t allow any change even under different conditions |
| C．leave no room for improvement. |
| D．can be used for many purposes |
| A．Scientists are different from ordinary people. |
| B．The Theory of Relativity?. |
| C．Exactness is the core(核心)of science. |
| D．Exactness and way of using tools are the keys to making of a scientist. |

Black Box
You never see them, but they're with you every time you fly. They record where you're going,how fast you're traveling and whether everything on your airplane is functioning normally. Their ability to resist almost any disaster makes them seem like something out of a comic (漫画) book.They're known as the black box.
When planes fall from the sky, as a Yemeni airliner did on its way to the Comoros Islands in the Indian Ocean on June 30, 2009, the black box is the best method for identifying what went wrong. So when a French submarine(潜水艇) discovered its homing signal five days later, it marked a huge step toward determining the cause of the disaster in which 152 passengers were killed.
In 1958. Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first model for a black box, which became a requirement on all US commercial flights by 1960. Early models often failed to resist crashes, however, so in 1965 it was completely redesigned. That same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to be easier to see.
Modem airplanes have two black boxes: a voice recorder, which tracks pilots' conversations, and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help experts reconstruct the aircraft's final moments. The boxes can resist powerful force and temperatures up t0 2,OOOoF. They're also able to send out signals from depths of 20,000 ft. Experts believe the boxes from Air France Flight 447 , which crashed near Brazil on June 1 , 2009 , are in water nearly that deep, but statistics say they're still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane's black boxes were never recovered.
【小题1】What can we leam about the black box from the passage?
| A．It helps an airplane function normally. |
| B．Its ability to avoid disasters is amazing. |
| C．It is necessary equipment on an airplane. |
| D．The idea for its design comes from a comic book. |
| A．the scene of the crash and the damage |
| B．data for analyzing the cause of the crash |
| C．the total number of passengers on board |
| D．homing signals sent by the pilot before the crash |
| A．make them easily identified |
| B．meet the international standards |
| C．caution people to handle them with care |
| D．distinguish them from the color of the plane |
| A．They have stopped sending homing signals. |
| B．They were destroyed somewhere near Brazil. |
| C．There is an urgent need for them to be restructured. |
| D．There is still a good chance of their being recovered. |

Another thing an astronaut has to learn about is eating in space．Food is weightless, just as men are．
Food for space has to be packed in special ways．Some of it goes into tubes that a man can squeeze into his mouth．Bite-sized cookies are packed in plastic．
There is a good reason for covering each bite．The plastic keeps pieces of food from traveling in the spaceship．On the earth very small pieces of food would simply fall to the floor．But gravity doesn’t pull them to the floor when they are out of the plastic in a spaceship．They move here and there and can get into a man’s eyes or into the spaceship’s instruments． If any of the instruments is blocked, the astronauts may have trouble getting safely home．
As astronauts travel on longer space trips, they must take time to sleep． An astronaut can fit himself to his seat with a kind of seat belt. Or, if he wants to, he can sleep in a sleeping bag which is fixed in place under his seat．But be careful he must put his hands under the belt when he goes to sleep．This is because he is really afraid that he might touch one of controls that isn’t supposed to be touched until later．
【小题1】Why would astronauts cover each bite of food in space？____
| A．Because small pieces of food would fall down to the floor． |
| B．Because weightless pieces of food might make trouble when they travel around． |
| C．Because they haven’t enough food for longer trips． |
| D．Because astronauts don’t want to waste food． |
| A．walk just as they do on the earth． |
| B．not eat anything because it’s dangerous． |
| C．control the spaceship when they are sleeping． |
| D．not litter small things or it will make trouble． |
| A．Because he thinks it is comfortable to sleep in that way in space． |
| B．Because he doesn’t want to touch any controls when he sleeps． |
| C．Because the instruments of the spaceship are easily broken． |
| D．Because he is afraid that the seat will move． |
| A．Eating and Sleeping in Space |
| B．How Astronauts Eat in Space |
| C．Food for Space |
| D．How Astronauts Sleep in Space |

The January fashion show, called Future Fashion, exemplified how far green design has come. Organized by the New York-based nonprofit Earth Pledge, the show inspired many top designers to work with sustainable fabrics for the first time. Several have since made pledges to include organic fabrics in their lines.
The designers who undertake green fashion still face many challenges. Scott Hahn, a cofounder with Gregory of Rogan and Loomstate, which uses all-organic cotton, says high-quality sustainable materials can still be tough to find. “Most designers with existing labels are finding there aren’t comparable materials that can just replace what you’re doing and what your customers are used to,” he says. For example, organic cotton and non-organic cotton are virtually indistinguishable once woven into a dress. But some popular synthetics, like stretch nylon, still have few eco-friendly equivalents(等同物).
Those who do make the switch are finding they have more support. Last year the influential trade show Designers & Agents stopped charging its participation fee for young green entrepreneurs who attend its two springtime shows in Los Angeles and New York and gave special recognition to designers whose collections are at least 25% sustainable. It now counts more than 50 green designers, up from fewer than a dozen two years ago. This week Wal-Mart is set to announce a major initiative aimed at helping cotton farmers go organic: it will buy transitional cotton at higher prices, thus helping to expand the supply of a key sustainable material. “Main-stream is about to occur,” says Hahn.
Some analysts are less sure. Among consumers, only 18% are even aware that eco-fashion exists, up from 6% four years ago. Natalie Hormilla, a fashion writer, is an example of the unconverted consumer. When asked if she owned any sustainable clothes, she replied, “Not that I’m aware of.” Like most consumers, she finds little time to shop, and when she does, she’s on the hunt for “cute stuff that isn’t too expensive.” By her own admission, green just isn’t yet on her mind. But thanks to the combined efforts of designers, retailers and suppliers—one day it will be.
【小题1】What is said about Future Fashion?
| A．It inspired leading designers to start going green. |
| B．It showed that designers using organic fabrics would go far. |
| C．It served as an example of how fashion shows should be organized. |
| D．It convinced the public that fashionable clothes should be made durable. |
| A．much more time is needed to finish a dress using sustainable materials |

One of my China Dialogue colleagues in Beijing recently bought a Philips energy-saving light bulb to replace a standard one．He was happy with his choice．It may have cost 30 yuan （just under US$4．50） - ten times the price of a filament （灯丝） bulb - but he wanted to save energy as part of his low-carbon lifestyle．And according to the shopkeeper, he would save, in the long run, much more than the 30 yuan he was spending．
Yet only one month later, his expensive light bulb blew up, before he had saved even a small part of the purchase price．Will he stick to his high-cost, low-carbon lifestyle?
China's environmental organizations have started to advocate low-carbon lifestyles and the decrease of carbon footprints to help fight against climate change．But they have overlooked one fact: in China, low-carbon living comes at a high cost．It means buying energy-saving bulbs and appliances, and environmentally friendly building materials and daily goods．Cost can no longer be the only standard for purchases．An energy-saving and environmentally friendly product is more expensive than a standard alternative - whether it's a simple light bulb or the house it shines．For average consumers, even buying an ordinary bulb is a huge burden．How can we persuade ordinary people to choose an energy-saving residence? This is not a trend they can afford to follow; perhaps this fashion is only for the rich．
Most consumers today do not cause huge carbon dioxide （CO2） emissions．Their responsibility lies not in choosing a low-carbon lifestyle today, but in avoiding a high-carbon life in the future．The principle of "common but differentiated responsibility" - a basis of sustainable development - can be applied here as well．
In China, low-carbon living still is resisted by a lack of social infrastructure（基础设施）. Even if your salary allows you to make that choice, nobody is there to help you accomplish it．
Consider energy-saving homes. You need to find out whether or not the developer has used natural materials wherever possible; how effective the insulation（绝缘物、隔热物） is; and what the green credentials of installed equipment are．You can read up a little, but you'll still be lucky to avoid being puzzled by the developers' marketing．Many so-called energy-saving buildings are nothing of the sort, and some are even more energy-hungry than the average home - as Li Taige warned in his article "Energy-efficient buildings? Not always", on China Dialogue last August．
【小题1】 What may probably be the best title of this passage?
| A．To purchase a cheap bulb - your wise alternative． |
| B．To choose an energy-saving residence - a must of your life |
| C．To learn a low-carbon lifestyle - each citizen's responsibility |
| D．To learn a low-carbon lifestyle - a promising but difficult purpose |
| A．Because the cost is a very important standard for purchases. |
| B．Because buying an ordinary bulb is very expensive. |
| C．Because energy-saving products are more expensive than the common alternatives. |
| D．Because rich people like to follow this trend. |
| A．Most of them are environmentally friendly. |
| B．They are musts of low-carbon lifestyle of Chinese. |
| C．They are huge burdens for Chinese people. |
| D．Many of them are more in name than in reality. |
| A．Using energy-saving bulbs and appliances is a fashion． |
| B．It's easy for most Chinese to try to learn a low-carbon lifestyle． |
| C．All citizens in China don’t have the same responsibility in living a low-carbon lifestyle． |
| D．Most Chinese families cannot afford to purchase an energy-saving residence. |
| A．informative and entertaining | B．supportive but cautious |
| C．negative but wise | D．positive and active |

Today is National Bike-to-Work Day. And on New York City’s jammed streets, people are cycling on hundreds of miles of new bike lanes. But New York’s widespread efforts to make streets safer for bikes have also left some locals complaining about the loss of parking spots and lanes for cars.
When the weather is good, Aaron Naparstek likes to pedal（用踏板踩）his two young kids to school on a special Dutch-made bicycle. Naparstek supports the new lane.
Aaron: The bike lane on Prospect Park West is really introducing a lot of new people to the idea that it’s possible to use a bike in New York City for transportation or to travel around. This is what 21st century New York City looks like.
Prospect Park West is still a one-way road, but where it used to have three lanes of car traffic, now it has two, plus a protected bike lane. Supporters say that makes the road safer for everyone, including pedestrians, by slowing down cars and taking bikes off the sidewalk. But some longtime residents disagree. Lois Carswell is president of a group called Seniors for Safety. She says the two-way bike lane is dangerous to older residents who are used to one-way traffic.
Lois: We wanted a lane — the right kind of lane that would keep everybody safe, that would keep the bikers safe. But we want it to be done the right way. And it has not been done the right way.
Craig Palmer builds bars and restaurants in Manhattan. I was interviewing him for a different story when he brought up the bike lanes all on his own.
Craig: I think the biggest problem is that Bloomberg put all these bike lanes in. You took what used to be a full street and you’re shrinking it.
Then there are the Hasidic Jews in Williamsburg, Brooklyn, who forced the city to remove a bike lane through their neighborhood. But polls show that the majority of New Yorkers support bike lanes by a margin of 56% to 39%. Bicycle advocate Caroline Samponaro of Transportation Alternatives calls that a mandate.
Caroline: If this was an election, we would have already had our victory. The public has spoken and they keep speaking. And I think, more importantly, the public is starting to vote with their pedals.
【小题1】What does Aaron mean by saying “This is what 21st century New York City looks like.”?
| A．There are hundreds of miles of new bike lanes in 21 st century New York City. |
| B．Drivers slow down their cars and bikes are taken off the sidewalk in New York. |
| C．Bikes are used as a means of transport in 21 st century New York City. |
| D．It’s possible to make the streets safe for pedestrians in New York. |
| A．Drivers lose parking spots and lanes for cars. |
| B．The two-way bike lane is dangerous to older residents. |
| C．We took what used to be a full street so the road is broader than before. |
| D．The removal of one bike lane through a neighbourhood in Brooklyn was not supported by the majority of New Yorkers. |
| A．the authority | B．the public | C．the supporters | D．the government |
| A．Ride on National Bike-to-Work Day |
| B．A New Bike Lane Appears in New York |
| C．A Bike Lane Divides New Yorkers |
| D．Who Wins an Election |
