Cities need to put efforts to deal with pollution and clear the air.
Chinese cities will need to put efforts to clear up the sky when a new department to improve regional air quality is set up by 2015, according to the latest plan released by the State Council．
Besides the existing pollution control program for S02, regional emission caps （區(qū)域排放上限） for other certain chemicals will be established in the three key air polluting areas— rhe Yangtze River Delta, Pearl River Delta and the Beijing-Tianjin-Hebei region．Coal-consumption caps will also be tried out in some areas, according to the plan．
The plan is aimed at dealing with regional air pollution—such as acid rain and smog—which have become increasingly obvious in China in recent years and caused a severe threat to people's health, Zhang Lijun, vice-minister of environmental protection, said in an interview on Monday.
The air quality in a city affects the regions nearby because pollutants （污染物）can travel through the atmosphere, said Chai Fahe, vice-director of Chinese Research Academy of Environmental Sciences．
“So efforts to reduce air pollution in a single city, targeting a certain pollutant will not oe enough," Chai said．
Zhang said the country's major industrial districts—the Yangtze River Delta, Pearl River Delta and the Beijing-Tianjin-Hebei region—have recorded more than 100 misty days annually in recent years．
These three regions, home to at least 200 million people, occupy only 6．3 percent of the country's area but consume 40 percent of the country's coal and produce half of its steel, according to official figures．
Studies also show that the visibility （能見度） in eastern regions of China has dropped by 7 to 15 km compared to that in the early 1960s, as a result of air pollution．
Liaoning province, the Shandong Peninsula, Wuhan in Hubei province and its surrounding area, the Changsha-Zhuzhou-Xiangtan region in Hunan province, the Chengdu-Chongqing region, and the western coast of the Taiwan Straits are also listed as areas to carry out such regional air pollution control programs, according to the plan．
The new plan also requires an improved air quality system, which will measure the pollution levels．"The current system, which only measures some major pollutants, cannot reflect the true picture．" said Chai．
小題1:It will not be enough to reduce air pollution in a single city because ______.
A．a(chǎn)ir pollution has been becoming more and more serious in recent years
B．a(chǎn)ir pollution like acid rain and smog is threatening people's health
C．a(chǎn)ir pollutants in a city can travel in the sky and affect nearby areas
D．a(chǎn)ir pollutants stay in fixed places over the cities
小題2:Suppose the visibility in eastern regions of China was 130 km in the early 1960s, the visibility there nowadays is           .
A．123 to 115 km
B．137 to 145 km
C．123 to 145 km
D．115 to 137 km
小題3:The main purpose of the passage is        .
A．to inform readers of the damage caused by air pollution
B．to introduce the new plan to control air pollution
C．to provide official figures of air pollution levels
D．to point out the regions affected by air pollution

Dogs have an understanding of fair play and become angry if they feel that another dog is getting a better deal, a new study has found.
The study looked at how dogs react when a companion is rewarded for the same trick in an unequal way. Friederike Range, a researcher at the University of Vienna in Austria, and her colleagues did a series of experiments with dogs who knew how to respond to the command “give the paw “. The dogs were normally happy to repeatedly give the paw, whether they got a reward or not. But that changed if they saw that another dog was being rewarded with a piece of food, while they received nothing.
“We found that the dogs hesitated significantly longer when obeying the command to give the paw,” the researchers write. The unrewarded dogs eventually stopped cooperating.
Scientists have long known that humans pay close attention to inequity. But researchers always assumed that animals didn’t share the trait. “The argument was that this is a uniquely human phenomenon,” says Frans de Waal, a professor of psychology at Emory University in Atlanta.
That changed in 2003 when he and a colleague did a study on monkeys. The monkeys had to hand a small rock to researchers to get a piece of cucumber in return. They were happy to do this. But if they saw that another monkey was getting a more delicious reward, a grape, for doing the same job, they would throw away the food and rock, and at some point just stopped performing.
In that experiment, the monkeys considered the fairness of two different types of payment. But when Range and her colleagues did a similar study with their trained dogs, testing to see if dogs would become upset if they only got dark bread when other dogs received sausage, they found that as long as the dogs got some kind of food payment, even if it wasn’t the most delicious kind, the animals would play along.
小題1:How did the dogs in Range’s study react to the order of “giving the paw”?
A．They took the order even without being rewarded.
B．They took the order only when rewarded.
C．They turned a deaf ear to repeated orders.
D．They hesitated longer when given repeated orders.
小題2: The research by Frans De Waal in 2003 ___________.
A．originated from Range’s research on dogs.
B．showed that animals do pay attention to inequity.
C．began the argument that only humans are aware of inequity.
D．was conducted to find out how monkeys reacted to humans’ orders.
小題3: Some monkeys in the research become angry because they found another monkey _______.
A．was given less work.
B．was given more food.
C．was given the same type of food.
D．was given more delicious food.
小題4: Range found that, compared with monkeys, dogs ____________.
A．care more about whether they are rewarded.
B．care less about what they are rewarded with.
C．care more about what they are ordered to do.
D．care less about who gives them orders.
小題5: What is the main idea of the passage?
A．Animals have various ways to show their anger.
B．Dogs are less intelligent than monkeys.
C．Dogs have a sense of fairness.
D．Most animals want to be rewarded equally.

Computer programmer David Jones earned $ 150,000 a year designing new computer games, yet he cannot find a bank prepared to let him have a check card (信用卡). Instead, he has been told to wait another two years until he is 18.
He works for a small firm in Liverpool, where most young people of his age are finding jobs. David”s biggest headache is what to do with his money. Though he has high payment, he cannot drive a car, or get credit cards.(信用卡)

Read a whole book in English? Me?
Yes, you. Believe it or not, that may be easier than you think. Not all classics are too difficult or complicated. So you’re not limited to the simplified versions. And the easier books are not all for children.
Books in their original versions may send you to the dictionary. And you might not understand everything you read. But reading one from cover to cover will give you a real sense of accomplishment（成就）. The key is to find the right books. Let’s take a look at these.
The Lion, the Witch and the Wardrobe (C.S. Lewis)
Stepping into an old wardrobe, four English schoolchildren find themselves in the magical world of Narnia. On this delightful land, they find friends among the many talking creatures. The children soon discover, however, that Narnia is ruled by the White Witch. Edmund, one of the children, falls under her power. Who can free Narnia? Only Aslan, the great and noble lion. He alone knows the Deeper Magic. But the children themselves must help fight the battle against the White Witch and those who serve her.
The Old Man and the Sea (Ernest Hemingway)
Santiago, an old Cuban fisherman, hasn’t caught any fish in more than 80 days. Sailing far out from land, the old man hooks an enormous fish. That begins an agonizing three day battle. First he struggles against the great fish. Then he must fight off the sharks that circle the little boat and threaten to eat his fish. Exhausted and bleeding, the old man arrives back at shore. But his fish, his beautiful fish . . .
Hemingway won the Nobel Prize for this superb story of strength and courage, of victory and regret.
A Wrinkle in Time (Madeleine Lingle)
Meg’s father, a U.S. government scientist, has been missing for many months. He had been experimenting with time travel when he mysteriously disappeared.
Now Meg, her little brother Charles Wallace and her friend Calvin will try to rescue him. But first they must outwit the forces of evil they encounter（遇到） on their journey through time and space. Can they find Meg’s father before it’s too late?
This novel is more than just a science fiction adventure. It’s an exploration of the nature of our universe.
The Pearl (John Steinbeck)
One day Kino, a poor Mexican pearl diver, finds a magnificent pearl. With it he dreams of buying a better life, new clothes and schooling for his son. Instead, it brings only evil. His wife pleads with him to get rid of it. "No," says Kino. "I will have my chance. I am a man." But when he kills a man who is trying to steal the pearl, Kino and his wife must run for their lives.This tale of dreams, justice and the power of greed is told simply and beautifully.
The Long Winter (Laura Ingalls Wilder)
It’s winter, 1880—1881, on America’s northern prairies. Mr. and Mrs. Ingalls and their four girls stay near the kitchen stove to keep warm. Heavy snowstorms cut them off even from neighbors. With the trains stopped, no supplies can reach the town. Food and fuel are running out. Day after day the girls must grind wheat for bread and twist hay to burn. At times they nearly lose the battle to keep their spirits up.
This story provides a fascinating glimpse into the life of early American settlers.

It was once thought that air pollution affected only the area immediately around large cities with factories and/or heavy automobile traffic. Today, we know that although these are the areas with the worst air pollution, the problem is literally worldwide. On several occasions over the past decade, a heavy cloud of air pollution has covered the entire eastern half of the United States and led to health warnings even in rural areas away from any major concentration of manufacturing and automobile traffic. In fact, the very climate of the entire earth may be affected by air pollution. Some scientists feel that the increasing concentration of carbon dioxide in the air resulting from the burning of fossil fuels(coal and oil) creating a greenhouse effect-holding in heat reflected from the earth and raising the world’s average temperature. If this view is correct and the world’s temperature is raised only a few degrees, much of the polar ice cap will melt and cities such as New York, Boston, Miami, and New Orleans will be under water.
Another view, less widely held, is that increasing particulate matter in the atmosphere is blocking sunlight and lowering the earth’s temperature-a result that would be equally disastrous（災(zāi)難的）. A drop of just a few degrees could create something close to a new ice age, and would make agriculture difficult or impossible in many of our top farming areas. At present we do riot know for sure that either of these conditions will happen(though one recent government report prepared by experts in the field concluded that the greenhouse effect is very likely). Perhaps, if we very lucky, the two tendencies will offset each other and the world’s temperature will stay about the same as it is now.
小題1:As pointed out at the beginning of the passage, people used to think that air pollution ______.
A．caused widespread damage in the countryside
B．a(chǎn)ffected the entire eastern half of the United States
C．a(chǎn)lmost brought worldwide effect
D．existed merely in urban and industrial areas
小題2:As far as the greenhouse effect is concerned, the author _____________.
A．shares the same view with the scientists
B．is uncertain of its occurrence
C．rejects it as being ungrounded（無根據(jù)的）
D．thinks that it will increasingly destroy the world soon
小題3:It can be inferred from the passage that                   .
A．raising the world’s temperature a little would not do much harm to life on the earth
B．lowering the world’s temperature a little would lead to agricultural disasters
C．a(chǎn)lmost no temperature variations have occurred over the past decade
D．the world’s temperature will remain stable forever
小題4:This passage is primarily concerned with             .
A．the greenhouse effect in the world
B．the measures to adjust the climate
C．the potential effect of air pollution
D．the measures to protect the environment

We hear with our ears, right? Yes, but scientists have known for years that we also hear with our eyes. In a study published in 1976, researchers found that people combined both auditory cues(聽力提示) and visual ones，like mouth and face movements, when they heard speech.
A new study that looks at a different set of sensory cues adds to a growing body of evidence that suggests such combination is natural. In a paper, Bryan Gick and Donald Derrick report that people can hear with their skin.
The researchers had volunteers listen to spoken syllables. Meanwhile, they connected the volunteers to a device that would blow a tiny puff (氣流) of air onto the skin of their hands or necks. The syllables included “ba” and “pa”, which produce brief puffs from the mouth when spoken, and “da” and “ta,” which do not produce puffs. They found that when listeners heard “da” or “ta” while a puff of air was blown onto their skin, they considered the sounds as “ba” or “pa”.
Dr. Gick said the findings were similar to those from the 1976 study, in which visual cues defeated auditory ones — volunteers listened to one syllable but thought it another because they were watching a video of mouth movements corresponding to the second syllable. In his study，he said，cues from sensory receivers on the skin defeated the ears as well. “Our skin is doing the hearing for us,” he said.
Dr. Gick noted that it would normally be rare that someone actually sensed a puff of air produced by another, although people might occasionally sense their own puffs. “What’s so persuasive about this particular effect,” he added. “is that people are picking up on this information that they don’t know they are using.” That supports the idea that combining different sensory cues is natural.
Dr. Gick said the finding also suggested that other sensory cues might be at work in speech perception(知覺) — that, as he put it, “we are these fantastic perception machines that take in all the information available to us and combine it faultlessly.”
小題1:“Da” or “ta” were considered as “ba” or “pa” when __________.
A．they were spoken quickly
B．puffs of air were blown onto the listener’s skin
C．they were pronounced using a special device
D．they were made with face movements
小題2:Which of the following statements is TRUE?
A．Humans combine different sensory cues through experience.
B．Dr. Gick’s new study is more important than the one in 1976.
C．People sometimes can sense their own puffs when speaking
D．Only auditory and visual cues are at work in speech perception.
小題3:What is the best title of the text?
A．We Can Hear with Our Skin
B．Our Visual Cues Is Doing the Hearing for Us
C．Facial Expressions Are Important
