Unlike traditional commercials, Public Service Advertisements（PSA）are primarily designed to inform and educate rather than sell a product or service. The goal of a PSA is not to make a big sale, but rather to change public opinion and raise awareness for a problem.
Smokey Bear has been a recognized symbol of the protection of America’s forests from fire. It is created to educate the public about the dangers of wildfires. Smokey Bear was started in 1944 with the slogan, “Smokey Bear Says—Care will prevent 9 out of 10 forest fires”. Smokey Bear’s later slogan, “Remember! Only You Can Prevent Forest Fires”, was created in 1947 by the Advertising Council in America. In April 2001, the message was changed to “Only You Can Prevent Wildfires”.
The wildfire prevention campaign with Smokey Bear is one of the longest and most successful campaigns in advertising history. The Advertising Council often was in partnership with other organizations and groups to create various advertising for Smokey Bear since 1944.
The Advertising Council teamed with Walt Disney Company to create a series of PSAs. The ads feature（以···为形象）characters form the classic film Sleeping Beauty and aim to reach parents and children. The lovely Bambi also appeared in the advertisements. Mickey Mouse is much more popular throughout the country.
Those PSAs, which appear on television, on the radio, in the newspaper and on the website continue to remind Americans about the importance of wildfire prevention have helped to reduce the number of acres burned annually by wildfires. According to recent survey, Smokey Bear and his famous words of wisdom “Only You Can Prevent Wildfires” are recalled by 3 out of 4 adults.
In addition to the PSA campaign, Smokey Bear has his own U.S. postage stamp and website for more information about wildfire prevention. From the website, you can also learn all about wildfires and how we can protect our forests.

The fourth round of heavy smog to hit Beijing in four weeks has sent more people to the hospital with respiratory (呼吸的) illnesses and led to calls for laws to control the pollution.
Pan Shiyi, a celebrity, said he is planning to propose a Clean Air Act to the local government. As a representative to the Beijing Municipal People's Congress, he started an online survey at 9:20 a.m. Within three hours, more than 25,000 web users, or 99 percent of total respondents (应答者) , welcomed his proposal.
They have good reasons to stand alongside Pan. The latest round of haze（雾霾）reduced visibility to under 500 meters in many parts of the city. The smog has also led to a great increase in respiratory illnesses, particularly among children and the elderly. Anxious parents and doctors almost all blame the smoggy air for the illnesses. Though most schoolchildren are home for the winter holidays, the bad air can easily move indoors. Besides, ordinary medical masks fail to provide enough protection, so some people have turned to gas masks.
The causes of the frightening smog are rather mysterious, though experts blame too much emissions (排放) and the mountains around Beijing that trap pollution in winter, unless there is enough wind to clear it away. Some critics blamed China’s top two oil firms, China National Petroleum Corp and China Petrochemical Corporation, saying the companies’ outdated production technologies produce large quantities of high-polluting gas fuel.[来源:学|科|网]
Meanwhile, some Beijingers have moved their brainstorming discussion to computers. If Pan’s proposal for a Clean Air Act is adopted, netizens say the new law should include items providing for “car-free days” in times of smog, higher standards for vehicle fuel, stricter limit to industrial and engine gas emissions, and more effective protection for the public.
Beijing is not the only city that has ever lost the blue sky. Five days of thick fog caused thousands of deaths in Britain in December 1952, urging the government to pass the first Clean Air Act in 1956, which introduced smokeless zones and cleaner fuels to reduce pollution. That may provide some experience for Beijing to refer to.
【小题1】Why did Pan Shiyi started an online survey?
| A．To know the public’s opinions on pollution |
| B．To tell people the danger of the smoggy weather |
| C．To call on people to support his proposal |
| D．To collect supporting evidence for his proposal |
| A．People are clear about the causes of the smoggy weather. |
| B．Children staying indoors will not get respiratory illnesses. |
| C．Smog is worse for people with lower resistance to diseases. |
| D．Masks can give people protection against the smoggy weather. |
| A．suggest Beijing should learn from other countries |
| B．let people know many places have this problem |
| C．tell people the situation in Britain is worse |
| D．call on the government to pass Britain’s Clean Air Act |
| A．The Use of Gas masks and Engines |

Electrical devices(仪器)could soon use power made by human energy. Scientists say they have developed an experimental device that produces electricity from the physical movement of a person walking. British scientist Max Donelan and other scientists in Canada and the United States developed the device.
The device connects to a person’s knee. As the person walks, the device captures energy each time the person slows down. To do this, the device helps with the slowing down movement of the leg. The movements of the walking person push parts of a small machine
that produces electricity. Using the device, an adult walking quickly could produce thirteen watts of electricity in just a minute. Donelan says walking at that speed could produce enough power to operate a laptop computer for six minutes.
There are several possible uses for the device. Developers say it could help people who work in areas without electricity to operate small computers. The device could also be used in hospitals to operate heart pacemakers(起搏器). It could even be used to assist in the movement of robotic arms and legs.
The experimental version of the device weighs about one and a half kilograms, but it is too costly for most people to buy. But the researchers hope to make a lighter, less costly version. An improved version shou1d be ready in one year.
The developers hope the device will one day help developing countries. Near1y twenty five
percent of people around the world live without electric power.
A similar product was invented in 2005 by Larry Rome of the University of Pennsylvania. He created a bag carried on a person’s back that also produces power from wa1king.The knee device does not produce as much electricity as the bag. But the bag requires the walker to carry a load of twenty to thirty kilograms.
【小题1】 The second paragraph mainly talks about .
| A．who developed the device |
| B．how the device works |
| C．several possible uses for the devices |
| D．how much electricity the device can produce |
| A．produces power without adding more loads to the walker |
| B．can produce more power in a much shorter time |
| C．needs to be equipped with a battery |
| D．can help the walker wa1k faster |
| A．help housewives operate the washing machine |
| B．make it much easier for us to go online |
| C．produce more electricity than that invented by Larry Rome |
| D．be applied in medicine to operate heart pacemakers |

How long do you want to live? How many years might be added to a life? Do you want to live another 100 years or more? Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.（寿命）
“I think we are knocking at the door of immortality(永生) , " said Michael Zey, a Montclair State University business professor and author of two books on the future. "I think by 2075 we will see it and that's a conservative estimate(保守的估计)."
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology(纳米技术) make it likely that humans will live in the future beyond what has been possible in the past. "There is a great push so that people can live from 120 to 180 years," he said. "Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.
However, many scientists who research into ageing are doubtful about it and say the human body is just not designed to last past about 120 years. Even with healthier lifestyles and less disease, they say the failure of the brain and organs will finally lead all humans to death.
Scientists also differ on what kind of life the super aged might live. "It remains to be seen if you pass 120,you know, could you be healthy enough to have good quality of life?" said Leonard Poon, director of the University of Georgia Gerontology Centre. "At present people who could get to that point are not in good health at all."
【小题1】By saying "we are knocking at the door of immortality", Michael Zey means ______.
| A．they have got some ideas about living forever |

| D．they are able to make people live past the present life span |
| A．people can live from 120 to 180 |
| B．it is possible for humans to live longer in the future |
| C．the human body is designed to last past about 120 years |
| D．it is still doubtful how long humans can live |
| A．using genes as well as nanotechnology |
| B．the idea of living beyond the present life span |
| C．a great push |
| D．the conservative estimate |

How to be Prepared
Electricity, water, gas and telephone may not be working after an earthquake. The police and fire department are likely to be tied up. You should be prepared to take care of yourself for at least three days, preferably for a week.
This list can also be applied to other disasters, such as floods or wildfires.
1. food and water (a gallon a day per person)
2. a first aid kit
3. a fire extinguisher suitable for all types of fires
4. flashlights, a portable radio extra batteries
5. blankets, clothes, shoes and money (ATMs may not work)
6. baby and pet food
It’s also a good idea to decide beforehand how and where your family will reunite if separated during a quake and to conduct in-home practice drills.
During an Earthquake
If you are indoors, stay there. Get under and hold onto a desk or table, or stand against an interior wall. Stay away from exterior walls, glass, heavy furniture, and stay away from windows and outside walls and do not use the elevator.
If you are outside, get into the open, stay into the open, stay away from buildings, power lines or anything else that could fall on you.
If you are driving, move the car out of traffic and stop, avoid parking under or on bridges or overpasses, Try to get clear of trees, light posts, signs and power lines.
If you are in a crowded public place, avoid panicking and do not rush for the exit. Stay low and cover your head and neck with your hands and arms.
After an Earthquake
If the phone is working, only use it in case of emergency. Likewise, avoid driving if possible to keep the streets clear for emergency vehicles.
Be aware that items may fall out of cupboards or closets when the door is opened, and also that chimneys can be weakened and fall with touch. Check for cracks and damage to the roof and foundation of your home.
Listen to the radio for important information and instructions. Remember that aftershocks, sometimes large enough to cause damage in their own right, generally follow large quakes.
If you leave home, leave a message telling friends and family your location.
【小题1】Which of the following items is unnecessary to prepare before an earthquake？

The olinguito（小尖吻浣熊）is new to science. Although lt has been living in the cloud forests of South Amcrica for some time.
Scientists say the olinguito is the first new carnivore（食肉动物）discovered In the Americas in more than 30 years. It is a hairy orange-brown creature with a sweet face and big eyes The animal has small. rounded ears and lives in the trees An adult weighs one kilogram and measures about 75 centimeters. with half of those centimeters taken up by its ringed tail Most of the time. it likes to eat fruit, although it also eats meat. Active at night, the animal has lived in Colombia and Ecuador for a long time. But the olinguito did not exist in science books before now.
Kristofer Helgen, director at the National Museum in Washington, led the research team that confirmed the existence of the olinguito. It had been mistaken more than a century ago for a look-alike animal -- a similar but larger olingo(尖吻浣熊). Mr. Helgen had been studying olingos in a museum for ten years. At that time. he observed a difference in the size and shape of the heads and teeth. That led him on an effort to prove he was looking at an animal never before described by science. He got lucky when he communicated with a zoologist in Ecuador. The animal expert there made a short video that shows an olinguito in the trees. The video confirms that the oiinguito is different from the olingo Mr. Helgen says tens of thousands of olinguitos live in the wild and are not in danger of disappearing forever. Human beings, however, are moving closer to the olinguito habitat in the Andean cloud forests. The research team estimates that 42 percent of historic olinguiio habitat has been removed
【小题1】Comparcd with most carnivores. the olinguito may seem more _____.
| A．terrble | B．fierce | C．clever | D．lovely |
| A．it was mistaken for another species |
| B．it was active in the eveing |
| C．it was too small to be seen clearly |
| D．it covered itself by its long tail |
| A．Having been studying olingos for ten years. |
| B．The short video the animal expert made. |
| C．His communication with an expert in Ecuador. |
| D．Differences between olingos and olinguitos. |
| A．the olinguito could be made full use of |
| B．the number of olinguitos is in the conutrol |
| C．the clinguito is a completely new species up to now |

A scientist turns out to be able to see the future by offering each of some four-year-olds a piece of candy and watching how he or she deals with it. Some children reach eagerly for the treat they see. Some last a few minutes before they give in. But others are determined to wait until the last moment.
By the time the children reach high school, something remarkable has happened. A survey found that those who as four-year-olds had enough self-control to hold out generally grew up to be more popular, adventurous, confident and dependable. The children who gave in to temptation(诱惑) early were more likely to be lonely, easily frustrated and inflexible(顽固的)．
Actually, the ability to delay reward is a sign of emotional intelligence which doesn't show up on an IQ test.
The hardware of the brain and the software of the mind have long been scientists' concerns. But brain theory can't explain what we wonder about most, like the question why some people remain upbeat in the face of troubles that would sink a less resistant soul.
Here comes the theory of Daniel Goleman, writer of Emotional Intelligence: when it comes to predicting people's success, brain ability measured by IQ may actually matter less than the qualities of mind once thought of as “character”．
EQ is not the opposite of IQ. What researchers have been trying to understand is how they work together; how one's ability to handle stress, for instance, affects the ability to concentrate and put intelligence to use. Among the ingredients (要素) for success, researchers now generally agree that IQ counts for about 20%; the rest depends on everything from social class to luck.
While many researchers in this relatively new field are glad to see emotional issues finally taken seriously, some few fear EQ invites misuse.
【小题1】The experiment with the four-year-olds makes it clear that ________.
| A．the age of 4 is a proper time for scientific experiment |
| B．emotional intelligence won't show up until adolescence |
| C．the ability of self-control plays a role in personal success |
| D．candy can be used to measure a person's emotional intelligence |
| A．There is no link between EQ and IQ. |
| B．The higher a person's IQ is, the higher his or her EQ is. |
| C．Some people can be blessed with lots of both, but some with little of either. |
| D．Scientists are trying to discover the way in which EQ and IQ work together. |
| A．kind | B．floating | C．excited | D．optimistic |
| A．To amuse both the children and readers. |
| B．To prove the scientist’s wisdom. |
| C．To introduce the topic of the text. |
| D．To show us how to do an IQ test. |
| A．Information about famous people with high EQ. |
| B．Examples showing the opposite voice about EQ. |
| C．Some reasons why EQ is relatively new field. |
| D．Strong demands for basic emotional education. |

Australian scientists are trying to give kangaroo-style stomachs to cattle and sheep in order to cut the greenhouse gases they send out，which is thought to be responsible for global warming．
Thanks to special bacteria in the stomachs，kangaroo flatulence（肠胃气胀）contains no methane（甲烷）and scientists want to transfer that bacteria to cattle and sheep which produce large quantities of the harmful gas．
While the usual image of greenhouse gas pollution is a huge factory chimney pushing out carbon dioxide，farm animals’ passing wind contributes to a surprisingly high percentage of total emission（排放物）in some countries．
“Fourteen percent of emissions from all sources in Australia is from methane from cattle and sheep，’’said Athol Klieve，a senior research scientist with the Queensland state government．
“And if you look at another country such as New Zealand，which has got a much higher agricultural base，they are actually up around 50 percent，”he said．
Researchers say the bacteria also make the digestive process much more efficient and could potentially save millions of dollars in feed costs for farmers．
But it will take researchers at least three years to isolate the bacteria before they can even start to develop a way of transferring it to cattle and sheep．
Another group of scientists，meanwhile，has suggested Australians should farm fewer cattle and sheep and just eat more kangaroos．And about twenty percent of health-conscious Australians are believed to eat the national symbol already．
“It’s low in fat，it’s got high protein levels and it’s very clean in the sense that basically it’s the free-range（放养的）animal，”said Peter Ampt of the University of New South Wales’s institute of environmental studies．
【小题1】The passage mainly talks about ________.
| A．a better way to prevent air pollution |
| B．the danger of methane from farm animals |
| C．possible solutions to protecting environment |
| D．a recent research on global warming |
| A．prevent them from sending out harmful gases |
| B．promote Australian farming |
| C．protect Australian ecosystem |
| D．make the most of the special bacteria |
| A．to reduce the number of animals raised on farms |
| B．to eat more kangaroos rather than keep more sheep and cattle |
| C．to eat more plants rather than beef and mutton |
| D．to grow more trees to absorb carbon dioxide |
| A．it is easy to transfer the bacteria to cattle and sheep |
| B．farm animals are to blame for global warming in some countries |
| C．cattle and sheep produce more methane than kangaroos |
| D．less cattle and sheep are raised in New Zealand |

Can people change their skin color without suffering like pop king Michael Jackson? Perhaps yes. Scientists have found the gene that determines skin color.
The gene comes in two versions, one of which is found in 99 per cent of Europeans. The other is found in 93 to 100 per cent of Africans, researchers at Pennsylvania State University report in the latest issue of Science.
Scientists have changed the color of a dark-striped zebrafish（斑马鱼） to uniform gold by inserting a version of the pigment (色素) gene into a young fish. As with humans, zebrafish skin color is determined by pigment cells, which contain melanin (黑色素). The number, size and darkness of melanin per pigment cell determine skin color.
It appears that, like the golden zebrafish, light-skinned Europeans also have a mutation (变异) in the gene for melanin production. This results in less pigmented skin.
However, Keith Cheng, leader of the research team, points out that the mutation is different in human and zebrafish genes.
Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays of the sun (太阳光紫外线), which can cause skin cancer.
But when modern humans leave Africa to live in northern latitudes, they need more sunlight on their skin to produce vitamin D. So the related gene changes, according to Cheng.
Asians have the same version of the gene as Africans, so they probably acquired their light skin through the action of some other gene that affects skin color, said Cheng.
The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin color without damaging it like chemical treatment did on Michael Jackson.
【小题1】The passage mainly tells us that ________.
| A．people can not change their skin color without any pain |
| B．the new discovery could lead to research into ways to change skin color safely |
| C．pop king Michael Jackson often changed his skin color as he liked |
| D．scientists have found out that people’s skin color is determined by the gene |
| A．nowadays people who want to change their skin color have to suffer a lot from the damage caused by the chemical treatment |
| B．Europeans and Africans have the same gene |
| C．the new discovery could help to find medical treatments for skin cancer |
| D．there are two kinds of genes |
| A．find the different genes of humans’ |
| B．prove the humans’ skin color is determined by the pigment gene |
| C．find out the reason why the Africans’ skin color is dark |
| D．find out the ways of changing people’s skin color |
| A．they are born light-skinned people |
| B．light-skinned Europeans have mutation in the gene for melanin production |
| C．they have fewer activities outside |
| D．they pay much attention to protecting their skin |
