Against the supposition（假设）that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.
This finding suggests that taking steps to prevent northern forest to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.
This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.
Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone（臭氧）levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling.
“We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere.” Scientists tracked the change in amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicated, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.According to the new findings, taking steps to prevent northern forest fires may _______.
| A．result in a warming climate |
| B．cause the forest fires to occur more frequently |
| C．lead to a longer fire season |
| D．protect the forests and the environment there |
The following are all the immediate effects after a forest fire EXCEPT _________.

| B．the levels of ozone which is a type of oxygen increase |
| C．snow on the ground mirrors more sunlight back into space |
| D．ashes from the fire fall on the ice surface and take in more radiation from the sun |
Earlier studies about northern forest fires _________.
| A．analyze all aspects of how northern fires influence climate |
| B．indicate that forest fires will pollute the atmosphere |
| C．suggest that people should take measures to protect environment |
| D．suggest that the fires will speed up climate warming |
The underlined part “soaked up” in the last paragraph most probably means ________.
| A．released | B．absorbed | C．created | D．distributed |
From the passage we can draw a conclusion that forest fires in Alaska, Canada and Siberia may __________.
| A．warm the climate as the supposition goes |
| B．allow more snow to reflect more sunlight into space and thus cool the climate |
| C．destroy large areas of forests and pollute the far-off sea ice |
| D．help to gain more energy rather than release more energy |
The idea about the phoenix goes back to Ancient Egypt, where we find the phoenix described as a handsome, eagle-like bird, with part-golden, part-red plumage, that spent most of its life in the Arabian deserts. It was rarely seen and according to one version of the story, only appeared in Egypt once every five hundred years, when it flew to Heliopolis, “city of the sun”, and deliberately burnt itself to ashes by settling on the altar (祭坛) flame there! However, it seems it did not really die because from those same ashes a young, fully formed phoenix was born and flew away, apparently back to Arabia.
It is pretty obvious that no one has ever seen or will see a living phoenix. The interesting thing is that we can find certain clues which may explain one aspect of the Egyptians’ idea. It may sound unbelievable, but some birds are apparently quite charmed by flames and small fires, especially members of the crow family. One zoologist actually proved this by setting fire to some straw near to a tame（驯养的）rook, a large black bird like a crow. Far from becoming nervous and backing away, the bird deliberately stood over the flames, with raised and vibrating wings. It didn’t get burnt, but the image it presented by its strange behavior was almost exactly like that shown in illustrations of the mythical phoenix!
Why birds should occasionally behave in this strange way is not clear. One idea is that they carefully use the heat of the flames to relieve the annoyance caused by their feather mites (虱) which all birds have. Whatever the reason, it is quite possible that the Ancient Egyptians saw birds behaving in this way, from time to time, and used it as the basis of their phoenix myth, adding fanciful details which closely linked it to their worship of the sun and their belief in resurrection.
Nowadays, the phoenix is much less important to us than it was to the Egyptians. But the logo of modern fire insurance companies, which employ the phoenix as one of their symbols, refers that in one sense the idea of it remains. According to the passage, the phoenix _________ .
| A．is a handsome and eagle-like bird living in Arab |
| B．used to be seen when the Egyptians held religious activities |
| C．has never really existed in the world |
| D．is the king of all kinds of birds |
The reason why birds stand above flames is probably that _________ .
| A．the phoenix used to do so | B．they may get rid of the mites |
| C．they want to burn their feather | D．they can heat themselves |
Which of the following statements is NOT correct?
| A．The ancient Egyptians worshiped the phoenix. |
| B．The scientists have discovered why birds are attracted by fire. |
| C．The modern people still favor the idea of the phoenix. |
| D．The mythical tales about the phoenix were based on facts. |
Which of the following is closest to the underlined word “resurrection” in the 3rd paragraph?
| A．living forever | B．offering warmth |
| C．coming back to life | D．staying healthy |
What does the phoenix probably mean in the logo of a fire insurance company?
| A．Our company can protect you from being harmed by fire. |
| B．If your property is destroyed by fire, we will help you build it up again. |
| C．Our company will always be energetic and wealthy. |
| D．If needed, we will save you at the risk of losing lives. |

Hans was an honest fellow with a funny round good-humored face. Living alone, every day he worked in his garden. In all the countryside there was no garden so lovely as his. All sorts of flowers grew there, blooming in their proper order as the months went by, one flower taking another flower’s place, so that there were always beautiful things to see, and pleasant odors to smell.
Hans had many friends, the most devoted being the Miller. So devoted was the rich Miller to Hans, that he’d never go by his garden without plucking a large bunch of flowers or a handful of sweet herbs, or filling his pockets with fruits. The Miller used to talk about noble ideas, and Hans nodded and smiled, felling proud of having such a friend.
The neighbors thought it strange that the rich Miller never gave Hans anything in return, though he had hundreds of sacks of flour, many cows and sheep; but Hans never troubled his head about these, and nothing gave him greater pleasure than to listen to all the wonderful things about the unselfishness of true friendship.
In spring, summer, and autumn Hans was very happy, but when winter came, and he had no fruit or flowers to sell, he suffered from cold and hunger. Though extremely lonely, the Miller never came to see him then.
“There’s no good in going to see Hans while the snow last.” The Miller said to his wife, “When people are in trouble they shouldn’t be bothered. So I’ll wait till the spring comes when he’s happy to give me flowers.”
“You’re certainly very thoughtful,” answered his wife, “It’s quite a treat to hear you talk about friendship.”
“Couldn’t we ask Hans up here?” said their son. “I’ll give him half my meal, and show him my white rabbits.”
“How silly you are!” cried the Miller; “I really don’t know what’s the use of sending you to school. If Hans came up here, and saw our warm fire, our good supper, and our red wine, he might get envious, and envy is a most terrible thing, and would spoil anybody’s nature. I am his best friend, and I’ll always watch over him, and see that he’s not led into any temptation. Besides, if Hans came here, he might ask me for some flour. Flour is one thing, and friendship is another, and they shouldn’t be confused. The words are spelt differently, and mean quite different things. Everybody can see that” He looked seriously at his son, who felt so ashamed that he hung his head down, and grew quite scared, and began to cry into his tea.
Spring coming, the Miller went down to see Hans. Again he talked about friendship. “Hans, friendship never forgets. I’m afraid you don’t understand the poetry of life. See, how lovely your roses are!”
Hands said he wanted to sell them in the market to buy back his things which were sold during the hard time of the winter.
“I’ll give you many good things. I think being generous is the base of friendship.” said the Miller. “And now, as I’ll give you many good things, I’m sure you’d like to give me some flowers in return. Here’s the basket, and fill it quite full.”
Poor Hans was afraid to say anything, he ran and plucked all his pretty roses, and filled the Miller’s basket, imagining the many good things promised by the Miller.
The next day he heard the Miller calling: “Hans, would you mind carrying this sack of flour for me to market?”
“I’m sorry, but I am really very busy today.”
“Well,” said the Miller, “considering that I’m going to give you my things, it’s rather unfriendly of you to refuse. Upon my word, you mustn’t mind my speaking quite plainly to you.”
Poor Hans was driven by his friendship theory to work hard for his best friend, leaving his garden dry and wasted.
One evening Hans was sitting by fire when the Miller came.
“Hans,” cried the Miller, “My little boy has fallen off a ladder and hurt himself, and I’m going for the Doctor. But he lives so far away, and it’s such a bad windy night. It has just occurred to me that you can go instead of me. You know I’m going to give you my good things, so you should do something for me in return.”
“Certainly,” cried Hans. He struggled into the stormy night, and got the doctor to ride a horse to the Miller’s house in time to save the boy. However, Hans got lost in the darkness, and wandered off into a deep pool, drowned.
At Hans’ funeral, the Miller said: “I was his best friend. I should walk at the head of the procession.” Every now and then he wiped his eyes with a handkerchief. .From the passage, we can learn that Hans ______.

The battle for the leadership of Britain’s Labour Party ended on September 25. Five candidates competed for the top job, but it turned out to be a tale of two brothers. Victory went to Ed Miliband, 40, with his elder brother David, 45, coming a close second. Ed’s Miliband’s job will now be to try to lead his party back into power and oppose Prime Minister David Cameron.
The two Milibands were both ministers in the Gordon Brown government. David Miliband, as Foreign Secretary, held the third most important post in UK politics. US Secretary of State Hillary Clinton described him as “vibrant and attractive”. Ed, who had a lesser role in government as Minister of Climate Change, was valued for his contribution to policy discussions and for his performance at the Copenhagen Conference on Climate Change last December.
The Miliband brothers were born to political parents. Their father, Ralph, was a Marxist scholar. He came to Britain from Belgium in 1940, fleeing the Nazis. Ralph Miliband was buried beside Karl Marx in London’s Highgate Cemetery. His wife Marion, the brothers’ mother, remains an active party member at 76.
The two brothers represent different wings of the Labour Party. David supported former Prime Minister Tony Blair; Ed was a follower of Blair’s great rival Gordon Brown, the last Labour PM.
“We’re determined to make sure that family comes before politics, and I don’t think there’s any chance that politics is going to get in the way,” David Miliband said before the vote.
After the result, the two embraced in front of the cameras.
In his acceptance speech, Ed Miliband said to his brother: “David, I love you so much as a brother. And I have such extraordinary respect for the campaign that you ran.”
But some feel their warm words were for the media and for the sake of party unity. There had been reports of anger on David’s part when his younger brother chose to stand against him. David may feel that the leadership was stolen from him-and by his own brother. Ed himself was reported to be concerned that he might have hurt David. According to the Guardian, after the result, Ed’s first reaction was: “what have I done to David?”
Ed suggested that he was prepared to make his brother shadow chancellor. But David has decided it is time to move on. He will not have a role in the Shadow Cabinet in the future.
In effect, he has fallen on his sword for the Party. David Miliband said the priority was to allow his brother to make a success of leading Labour: “I believe this will be harder if there is constant comparison with my comments and position as a member of the shadow cabinet.”. Ed Miliband became head of Britain’s Labour Party because ______.
| A．he played an important role in the previous British government. |
| B．his arguments at political discussions and his performance at an international conference |
| C．Hillary Clinton thought highly of him |
| D．his brother supported him both at home and politics. |

| B．Ralph Miliband came to Britain because of the Nazis. |
| C．Tony Blair, Gordon Brown and David Cameron are all Labour Party Prime Ministers. |
| D．David Miliband and Ed Miliband’s mother is still alive. |
.What can be inferred from the passage?
| A．David Miliband and Ed Miliband fought against each other both at home and politics. |
| B．Ed was concerned about David’s feelings after the election. |
| C．David and Ed were born into a political family. |
| D．David and Ed agreed with each other on most of the issues |
.What does the underlined sentence mean?

| C．Partners in public and enemy in private | D．Representatives of different wings of Labour Party |
From the health point of view we are living in an amazing age. We are free from many of the most dangerous diseases. A large number of once deadly illnesses can now be cured by modern medicine. It is almost certain that one day medicines will be found for the most stubborn remaining diseases. The expectation of life has increased greatly. But though the possibility of living a long and happy life is greater than ever before, every day we witness the unbelievable killing of men, women and children on the roads. Man vs the motor-car! It is a never-ending battle which man is losing.
Thousands of people the world over are killed or horribly killed each year and we are quietly sitting back and letting it happen.
It has been rightly said that when a man is sitting behind a steering wheel(方向盘), his car becomes the extension of his personality. There is no doubt that the motor-car often brings out a man’s very worst qualities. People who are normally quiet and pleasant may become unrecognizable when they are behind a steering-wheel. They say, they are ill-mannered and aggressive, willful as two-year-olds and completely selfish. A.. their hidden angers and disappointments seem to be brought to the surface by the act of driving.
The surprising thing is that society smiles so gently on the motorist and seems to forgive his behavior. Everything is done for his convenience. Cities are allowed to become almost uninhabitable because of heavy traffic; towns are made ugly by huge car parks; the countryside is ruined by road networks; and the deaths become nothing more than a number every year, to be easily forgotten.
It is high time a world rule was created to reduce this senseless waste of human life. With regard to driving, the laws of some countries are unbelievable lenient(宽容的) and even the strictest are not strict enough. A rule which was universally accepted could only have an obviously beneficial effect on the accident rate. Here are a few examples of some of the things that might be done. The driving test should be standardized and made far more difficult than it is; all the drivers should be made to take a test every three years or so; the age at which young people are allowed to drive any vehicle should be raised to at least 21; all vehicles should be put through strict tests for safety each year. Even the smallest amount of alcohol in the blood can damage a person’s driving ability. Present drinking and driving laws(where they exist) should be made much stricter. Speed limits should be required on all roads. Governments should lay down safety specifications for car factories, as has been done in the USA. All advertising stress power and performance should be banned. These measures may not sound good enough. But surely nothing should be considered as too severe if it results in reducing the number of deaths. After all, the world is for human beings, not motor-cars. .What is the main idea of this passage?
| A．Traffic accidents are mainly caused by motorists. |
| B．Thousands of people the world over are killed each year. |
| C．The laws of some countries about driving are to lenient. |
| D．Only stricter traffic laws can prevent accidents. |
. What does the author think of society toward motorists?
| A．Society laughs at the motorists. | B．Huge car parks are build in the cities and towns. |
| C．Victims of accidents are nothing. | D．Society forgives their rude driving |
.What does the author mean by saying “his car becomes the extension of his personality” in Paragraph 2?
| A．Driving can show his hidden qualities | B．Driving can show the other part of his personality |
| C．Driving can bring out his character | D．Driving can represent his manners |
. Which of the following is NOT mentioned as a way against traffic accidents?
| A．Perfect the road network | B．Stricter driving tests |
| C．Test drivers every three years | D．Raise age limit and lay down safety specifications |
. The author’s attitude towards the traffic situation is ______.
| A．confused | B．discontented | C．appealing | D．doubtful |
