This winter, the air quality over the north China plain was so bad that it was actually off the standard scale. The air pollution reached levels that the World Health Organization describes as dangerous. On Thursday, heavy smog blanketed most of northern and eastern China again.
It is reasonable to ask why the air pollution is so bad this winter. Weather conditions and topographic(地形學的) factors have been given as reasons, but, although contributing factors, these are not to blame. The worsening air pollution is linked to an energy mix that relies heavily on coal and to motor vehicle emissions(排放). But despite the astonishing growth of motor vehicles in our cities, it is the burning of coal that is the biggest cause of air pollution. More than half of the country's power plants are located in the eastern region and China's coal consumption has more than doubled in the past decade, reaching 3.8 billion tons last year, accounting for almost half the world's total coal consumption. And with coal occupying nearly 70 percent of the country's primary energy consumption, it has become critical to reduce the use of coal if we are to solve the nation's overall air pollution problem.
In the face of the poisonous air recently, one citizen said, "we have nothing but hot air to purify the skies". In fact, the government plans to have 350 billion yuan ($55.67 billion) investment in improving coal-fired facilities and limiting the use of yellow-label cars that do not meet the Euro I emissions standard and so on.
However, it would be far more effective to reduce emissions at the source, which means that the biggest challenge currently facing government departments is saying "no" to the country's air polluting offenders. According to the Joint Prevention and Control Plan on Air Pollution in Key Regions released recently by the State Council, the amount of coal the nation consumes is set to rise by 30 percent during the period of the 12th Five-Year Plan. This is not going to let anyone breathe easier.
This highlights a key problem when it comes to environmental issues in this country - economic development comes first. The fundamental cause of the worsening air pollution is the idea of economic growth at any cost, which has resulted in ever-worsening pollution. And the priority(優(yōu)先權(quán))given to economic growth presents another problem, namely the failure of existing environmental protection policies and regulations to control pollution. For instance, the current weak regulations covering emissions would suggest there has been a significant reduction in emissions when clearly this is not the case. Also those enterprises found breaking the regulations are still far lower than the cost of treating the pollution they produce. This means even if many large-scale enterprises with lagging production capacity(能力) fail to meet the requirements for environmental protection, the environmental protection department is incapable of shutting these enterprises down or forcing their relocation.
Dealing with air pollution requires taking action at the local level to reduce vehicle emissions and at the regional level to reduce industrial emissions. But it also requires giving more priority to environmental issues in policymaking. Our hope is that the environmental protection department will be truly capable of saying "no" to pollution, and it will raise standards and effectively enforce them, and that governments at all levels will prioritize quality of life not just economic growth.

解析試題分析:
本文介紹了中國空氣污染的情況,分析了造成污染的原因,提出解決污染問題的對策措施。造成污染的原因主要是燃煤和汽車排放,燃煤是最大原因;而根源卻在于“經(jīng)濟發(fā)展優(yōu)先”的觀念。作者指出,各級政府應(yīng)該將人們的生活質(zhì)量放在首位。
【小題1】主旨大意題。文章主要分析污染原因,提出問題對策,第一段只是為了引起人們對污染的嚴重程度的關(guān)注,引起下文。故答案為C.
【小題2】由第四段…which means that the biggest challenge currently facing government departments is saying "no" to the country's air polluting offenders, ,“十二五”期間煤消耗增長30%到第五段第一句話“突顯了一個關(guān)鍵問題,即‘經(jīng)濟發(fā)展優(yōu)先’”可知,經(jīng)濟發(fā)展優(yōu)先的觀念阻礙了從根源上減少排放。故答案為B。
【小題3】由第二段it is the burning of coal that is the biggest cause of air pollution一句可知,燃煤是造成污染越來越嚴重的根本原因。故選擇A項。
【小題4】污染越來越嚴重,燃煤是原因,但是根源卻在于“經(jīng)濟發(fā)展優(yōu)先”的觀念。所以解決污染問題的關(guān)鍵在于改變觀念。這就要求政府制定環(huán)保政策并有效實施。由最后一段But it also requires giving more priority to environmental issues in policymaking.可知B項正確。
【小題5】作者對于環(huán)境污染越來越嚴重感到深深的憂慮。從最后一段故答案為D.
考點:議論文。

When an ant dies, other ants take it out of the nest, often within an hour after its death. This behavior interests scientists and they wonder how ants know for sure—and so soon—that another ant is dead.
One scientist recently came up with a way to explain this ant behavior. Dong-Hwan Choe is a biologist, a scientist who studies animals and plants. He found that ants have a chemical on the outside of their bodies that signals to other ants, “I'm dead—take me away” when it is dead.
But there's a question to answer: As we know, if an ant is dead, it stops moving. But when an ant is sleeping or knocked unconscious, it is also not moving. However, other ants don't move the living ant out of the nest. How do they know this ant is not dead? Choe found that ants have another chemical on their bodies, which tells nearby ants something like, “Wait—I'm not dead yet” when it is not dead. Choe suspects that when an ant dies, the chemical that says, “Wait— I'm not dead yet” quickly goes away. When other ants detect the “dead” chemical without the “not dead yet” chemical, they move away the body.
To test his theory, Choe and his team put different chemicals on ants. When the scientists used the “I'm dead” chemical, other ants quickly moved the treated ant away. When the scientists used the “Wait—I'm not dead yet” chemical, other ants left the treated ant alone. Choe believes this behavior shows that the “not dead yet” chemical overrides the “dead” chemical when picked up by other ants. And that when an ant dies, the “not dead yet” chemical dies away. Other nearby ants then notice the remaining “dead” chemical and remove the body from the nest.
Understanding this behavior can help scientists figure out how to stop ants from invading new places and causing problems.

Early one morning, more than a hundred years ago, an American inventor called Elias Howe finally fell asleep. He had been working all night on the design of a sewing machine but he had run into a very difficult problem: It seemed impossible to get the thread to run smoothly around the needle.
Though he was tired, Howe slept badly. He turned and turned. Then he had a dream. He dreamt that he had been caught by terrible savages whose king wanted to kill him and eat him unless he could build a perfect sewing machine. When he tried to do so, Howe ran into the same problem as before. The thread kept getting caught around the needle. The king flew into the cage and ordered his soldiers to kill Howe. They came up towards him with their spears raised. But suddenly the inventor noticed something. There was a hole in the tip of each spear. The inventor awoke from the dream, realizing that he had just found the answer to the problem. Instead of trying to get the thread to run around the needle, he should make it run through a small hole in the center of the needle. This was the simple idea that finally made Howe design and build the first really practiced sewing machine.
Elias Howe was not the only one in finding the answer to his problem in this way.
Thomas Edison, the inventor of the electric light, said his best ideas came into him in dreams. So did the great physicist Albert Einstein. Charlotte Bronte also drew in her dreams in writing Jane Eyre.
To know the value of dreams, you have to understand what happens when you are asleep. Even then, a part of your mind is still working. This unconscious(無意識的), but still active part understands your experiences and goes to work on the problems you have had during the day. It stores all sorts of information that you may have forgotten or never have really noticed. It is only when you fall asleep that this part of the brain can send messages to the part you use when you are awake. However, the unconscious part acts in a special way. It uses strange images which the conscious part may not understand at first. This is why dreams are sometimes called “secret messages to ourselves”.
【小題1】According to the passage, Elias Howe was________.
A.the first person we know of who solved problems in his sleep |
B.much more hard-working than other inventors |
C.the first person to design a sewing machine that really worked |
D.the only person at the time who knew the value of dreams |
A.what kind of thread to use |
B.how to design a needle which would not break |
C.where to put the needle |
D.how to prevent the thread from getting caught around the needle |
A.he also tried to invent a sewing machine |
B.he got some of his ideas from dreams |
C.he was one of Howe’s best friends |
D.he also had difficulty in falling asleep |
A.strange images are used to communicate ideas |
B.images which have no meaning are used |
C.we can never understand the real meaning |
D.only specially trained people can understand them |

After a busy day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping enables your body to prepare itself for the next day.
There are four levels of sleep, each being a little deeper than the one before. As you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to the other.
Although your mind slows down, from time to time you will dream. Scientists who study sleep state that when dreaming occurs, your eyeballs begin to move more quickly (Although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement.
If you have trouble falling asleep, some people recommend breathing very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion the counting sheep will put you to sleep!

Passage 1
The information Highway is the road that links computer users to a large number of on-line services; the Web, e-mail, and software, to mention just a few. Not long ago, the information Highway was a new road, with not many users. Now, everyone seems to want to take a drive, with over 30 million families connected worldwide. Not surprisingly, this well-traveled highway is starting to look like a well-traveled highway. Traffic jams can cause many serious problems, forcing the system to close down for repair. Naturally, accidents will happen on such a crowed road, and usually victims are some files, gone forever. Then, of course, there’s Mr. Cool, with his new broad-band connection, who speeds down the highway faster than most of us can go. But don’t trick yourself; he pays for that speeding.
Passage 2

Back in old times, people had little knowledge about the universe and nature. Things we now consider to be common sense were mysteries to our ancestors.
Over the years, major breakthroughs have been made in science and many phenomena have been explained. But still, there are always questions we can't yet answer, and The Guardian has listed some of them.
1. What makes us human?
Just looking at your DNA won't tell you - human DNA is 99 percent identical to that of the chimpanzee and, believe it or not, 50 percent identical to a banana's! A lot of the things we once thought were unique about us - language and tool use, recognizing ourselves in the mirror and so on – have since been seen in other animals. Perhaps it's our culture that makes the difference or maybe our ability to use fire. It's also possible that our capacity (能力) for co-operation and our trading skills are what make us unique.
2. Why do we dream?
Given the fact that we spend around a third of our lives sleeping, shouldn't we know everything about it? Unfortunately, scientists are still searching for a complete explanation of what happens when we sleep and why we dream.
Austrian psychologist Sigmund Freud believed dreams were the expressions of wishes that we can't fulfill in our real lives. Others have wondered whether dreams are just random "noise" coming from a sleeping brain.
3. Could we someday live forever?
Apart from accidents, most people die because of diseases that can be treated and aging. And since many diseases, such as diabetes(糖尿。 and cancer, are diseases of aging, treating aging itself could be the key to extending our lives.
Our knowledge of what causes us to age - and what allows some animals to live longer than others - is expanding rapidly. And though we haven't quite worked out all the details, we've worked out some pieces of the puzzles such as DNA damage and metabolism (新陳代謝), which are all leading to the invention of drugs that can slow down the aging process.
If we're lucky enough to lengthen our lives, we might even get to see the day when all of these questions are answered.
【小題1】The main point of the passage is ______.
A.to inform people of the knowledge about the universe and nature |
B.to introduce major breakthroughs that have been made in science |
C.to present some questions we can't yet answer |
D.to explain what were once mysteries to our ancestors |
A.human beings are actually not different from other animals |
B.a(chǎn)nimals have completely different DNA from that of plants |
C.both animals and plants share the same amount of DNA |
D.DNA alone is not good enough to make humans different |
A.mysterious | B.unique | C.a(chǎn)dvanced | D.same |
A.What were mysteries to our ancestors are considered to be common sense now. |
B.Now we know much more about dreams than our ancestors did in the past. |
C.With the invention of new drugs people can possibly live even longer. |
D.If all the diseases can be treated people can theoretically live forever. |

Culture helps human societies survive in changing natural environment.For example, the end of the last Ice Age, beginning about 15,000 years ago, brought a big challenge to which humans had to adapt.Before this time, large parts of the northern hemisphere were covered in great sheets of ice that contained much of the earth' s water.In North America, large animals that wandered the vast tundra (冰原) provided people with food and materials for clothing and simple shelters.When the earth became warm, large Ice Age animals disappeared, and many land areas were covered by rising sea levels from melting ice.But people survived, they developed new technologies and learned how to survive on new plant and animal species. Finally some people settled into permanent villages, durable houses and farms.
Cultural adaptation has made humans one of the most successful species on the planet. Through history, major developments in technology, medicine, and nutrition have allowed people to reproduce and survive in ever-increasing numbers.The global population has risen from 8 million during the Ice Age to about 6 billion today.
However, the successes of culture adaptation can also create problems in the long run.Over the last 200 years, people have begun to use large quantities of natural resources and energy and to produce a great amount of material and chemical wastes.The global population now consumes some important natural resources—such as petroleum, wood, and minerals—faster than nature can produce them.Many scientists believe that in the process of burning fuels and producing wastes, people may be changing the global climate in unpredictable and possibly harmful ways.Thus, the adaptive success of the present-day global culture of production and trade may be temporary.
【小題1】What is the first paragraph mainly talking about?
A.How the human beings survived in the Ice Age. |
B.What the situation was like during the Ice Age. |
C.What caused the Ice Age to come to an end. |
D.Why the Ice Age was very important. |
A.stop developing any longer |
B.reduce the overuse of natural resources |
C.stop the global warming and using natural resources |
D.save more animals in case they all die out |
A.A very developed culture came into being. |
B.New technologies have been developed. |
C.Natural resources have been used up. |
D.Human activities have done damage to the balance of nature. |
A.Natural Environment Should Be Protected. |
B.The Success of Cultural Adaptation Is Not Permanent. |
C.The Global Population Is Increasing Since Ice Age. |
D.Human Beings Are Capable of Surviving on Earth. |
