题型:不详难度:来源:
Beijing had its biggest snowfall since 1951. Britain is suffering through its longest cold snap (寒潮) since 1981. And freezing weather is hitting the Deep South, including Florida’s orange groves and beaches.
Whatever happened to global warming?
Such weather doesn’t seem to fit with warnings from scientists that the Earth is warming because of greenhouse gases. But experts say the cold snap doesn’t contradict global warming at all—it’s just a temporary phenomenon in the long-term heating trend. “It’s part of natural variability,” said Gerald Meehl, a senior scientist. With global warming, he said, “we’ll still have record cold temperatures. We’ll just have fewer of them.”
Scientists say man-made climate change does have the potential to cause more frequent and more severe weather extremes. But experts did not connect the current cold snap to climate change.
So what is going on?
“We basically have seen just a big outbreak of Arctic air over populated areas of the Northern Hemisphere”, Arndt said.
In the atmosphere, large rivers of air travel roughly west to east around the globe between the Arctic and the tropics. This air flow acts like a fence to keep Arctic air restricted. But recently, this air flow has become bent into a zigzag (之字形) pattern, wandering north and south. If you live in a place where it brings air up from the south, you get warm weather. In fact, record highs were reported this week in Washington state and Alaska.
But in the eastern United States, like some other unlucky parts of the globe, Arctic air is coming from the north. And that’s how you get a temperature of 3 degrees in Beijing, a reading of minus-42 in mainland Norway, and 18 inches of snow in parts of Britain. The zigzag pattern arises naturally from time to time, but it is not clear why it’s so strong right now.

Ever since I was a small girl in school, I’ve been aware of what the school textbooks say about Indians. I am an Indian and, naturally, am interested in what the schools teach about natives of this land.
One day, I read that a delicacy(美味) of American Indian people was dried fish, which , according to the textbook, tasted “like an old shoe, or was like chewing on dried leather.” To this day I can remember my surprise, my anger and my sadness at reading these words. We called this wind-dried fish “sleet-shus”, and to us, it was our favorite delicacy and, indeed, did not  taste like shoe leather, and didn’t rot our teeth and bring about the various dietary problem that trouble Indian people in modern times. It took many hours of long and hard work to cure the fish in just this particular fashion. Early fur traders and other non-Indians must have agreed, for they often had this food as they traveled around isolated areas.
I brought the textbook home to show it to my father, leader of my tribe at that time. On this particular day, he told me in his wise and modest manner that the outside world did not understand Indian people, and that I should not let it prevent me from learning the good parts of education.
At a later time in my life, I had brought a group of Indian people to the country fairgrounds to sell Indian-made arts and crafts. My group was excited to make some money by selling Indian handicrafts. We thanked the man who showed us to our booth and told him it was nice of him to remember the people of the Indian community. The man expanded a little and remarked that he liked Indian people. “In fact,” he went on to state, “we are bringing some professional Indians to do the show!”
As we stood there in shock, listening to this uninformed outsider, I looked at my dear Indian companion, an eighty-year-old woman who could well remember the great chiefs of the tribe who once owned all the land of this country before the white man came bringing “civilization”, which included diseases and pollution. My friend said not a word, but took the hurt as Indian people have done for many years.
Of course, we all knew that the “professional Indian” were not Indians at all, but dressed in leather and dancing their own dances. And, anyway, how does one become a “professional Indian”?
45.Which of the following statements about “sleet-shus” is true?
A.It tasted like an old shoe.
B.Eating it was like chewing on dried leather.
C.It was delicious but bad for our teeth.
D.It must have brought pleasure to Indians as well as early business men.
46.What does the writer mean by saying “how does one become ‘a professional Indian’”?
A.Only the Indians know how to become professional Indians.
B.The outside civilization can help and Indian become a professional Indian.
C.An Indian is a born professional Indian.
D.The outside civilization can help white people become professional Indians.
47.After reading the passage, you don’t know __________.
A.what the writer’s profession is
B.what upset the writer and her friend at the county fair
C.why the writer went to the county fair
D.the writer’s attitude to the so-called civilization
48.This story is primarily about ___________.
A.customs of native Americans
B.how textbooks describe native Americans.
C.misunderstanding between people from different cultures
D.how an Indian becomes a “professional Indian”

D
Sadness is unpleasant, and in a society where personal happiness is prized above all else, there is little tolerance for falling in despair. Especially now we’ve got drugs for getting rid of sad feelings — whether it’s after losing a job, the break-up of a relationship or the death of a loved one. So it’s no surprise that more and more people are taking them.
But is this really such a good idea? A growing number of voices from the world of mental health research are saying it isn’t. They fear that the increasing tendency to treat normal sadness as a disease is playing fast and loose. Sadness, they argue, serves a useful purpose—and if we lose it, we lose out. Yet many psychiatrists insist not. Sadness has a nasty habit of turning into depression they warn. Even when people are sad for good reason, they should take drugs to make themselves feel better.
So who is right? Is sadness something we cannot live without or something horrible never to touch?
There are lots of ideas about why feeling sad should become part of human life. It may be a kind of self-protection, as other primates (灵长类) also show signs of sadness. A losing monkey that doesn’t show sadness after it loses a fight may be seen as continuing to challenge the winning monkey — and that could result in death.
In humans sadness has a further function: we may display sadness as a form of communication. By acting sad, we tell other community members that we need support.
Then there is the idea that creativity is connected to dark moods. There are plenty of great artists, writers and musicians who have suffered from depression or disorder. Scientists found that people with signs of depression performed better at a creative task, and negative moods make people think deeply over the unhappy experience, which allows creative processes to come to the front. There is also evidence that too much happiness can be bad for your career. A doctor found that people who scored 8 out of 10 on a happiness test were more successful in income and education than 9s or 10s. The happiest people lose their willingness to make changes to their lives that may benefit them.
53.The underlined word “this ” refers to ________.
A.taking medicine              B.falling in despair            C.losing a job            D.feeling sad
54.The author believes sadness is ________.
A.a good thing for people’s health       B.something horrible never to touch
C.a necessary function of humans’       D.always to be treated as depression
55.Some animals show their sadness in order to ________.
A.cheat their enemy               B.protect themselves 
C.comfort the loser               D.challenge the winner
56.We can infer from the last paragraph that ________.
A.people with great creativity tend to be happier   
B.unhappy experiences contribute to a greater career
C.too much happiness can be bad for your career
D.the happiest people are the most successful ones

London Underground
The world’s first subway was built in London in 1863. At the time, the government was looking for a way to reduce traffic problems in the city of London. The poor areas of the city were so crowded with people that it was almost impossible for horse carriages to get through. The city officials were interested in trying to make it possible for workers to live outside of London and travel easily to work each day. If people had a cheap and convenient way that they could depend on to go to and from work, they would relocate their homes outside of the city. This would help ease(减轻) the pressure of too many people living in the poor parts of London. From these problems, the idea of the London Underground, the first subway system was born.
The plans for building the Underground met with several problems and delays, but the fast track was finally opened in January 1863. A steam train pulled the cars along the fast underground track which was 6 kilometers (3. 7 miles) long. About 30,000 people got on the subway the first day.  Riders were treated to comfortable seats (standing up while the train was moving was not allowed), and pleasant decorations inside each of the cars. However, the smoke from the engine soon filled the air in the tunnels with ash and soot(煤灰), as well as chemical gases. Fans had to be put in the tunnels later to keep the air clean enough for people to breathe. Even with its problems, riding in the Underground did catch on. It carried 9 million riders in its first year.
40. What led the British government to build the London Underground?
A.  Traffic jams and pollution.
B.  Population and pollution.
C.  Overcrowding and traffic jams.
D.  The poverty and subway problems. 
41. How did the London Underground solve the smoke problem?
A.  It made the tunnels larger.
B.  It put fans in the tunnels.
C.  It cleaned the chemical gases in the tunnels. 
D.  It reduced the number of passengers riding in the train.
42. The underlined phrase “catch on” most probably means “______”.
A.  be troublesome         
B.  become popular and fashionable
C.  keep up with           
D.  seize
43. Which of the following is TRUE?
A.  To relocate the workers’ homes outside London,the government built the subway.
B.  There were so many problems and delays that in 18th century the first subway opened.
C.  The subway greatly eased the pressure of traffic.
D.  There were not enough seats for the passengers the first day the subway opened.

The geographical location of a country and its physical characteristics are very important to its development and progress. he United States is very fortunate in this respect.
First of all, it has a good climate. In almost all sections of the country it is possible to live comfortably during the whole year. It is true that in the south it sometimes gets very hot, and in the north very cold. But the people who live in these regions become accustomed to the climate and never suffer very much when the weather is either very hot or very cold.
In a large country there is usually a great variety of different physical characteristics. In the United States, there are wide plains and high mountains, thousands of lakes and rivets of all sizes, cool forests and hot deserts, and a coastline several thousand miles long.
The many lakes and rivers, as well as the long coastline, have been of great importance to the development of the country, since they made possible the easy transportation of people and all the things people need. Transportation by water is still necessary and important. In modern times, however, trains, automobiles, trucks and airplanes are doing much of the work which was formerly done by ships and boats.

Passage seven(Stricter Traffic Law can Prevent Accidents)
From the health point of view we are living in a marvelous age. We are immunized from birth against many of the most dangerous diseases. A large number of once fatal illnesses can now be cured by modern drugs and surgery. It is almost certain that one day remedies will be found for the most stubborn remaining diseases. The expectation of life has increased enormously. But though the possibility of living a long and happy life is greater than ever before, every day we witness the incredible slaughter of men, women and children on the roads. Man versus 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, 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 swear, they are ill-mannered and aggressive, willful as two-years-olds and utterly selfish. All their hidden frustrations, disappointments and jealousies seem to be brought to the surface by the act of driving.
The surprising thing is that society smiles so benignly on the motorist and seems to condone his behaviour. Everything is done for his convenience. Cities are allowed to become almost uninhabitable because of heavy tragic; towns are made ugly by huge car parks; the countryside is desecrated by road networks; and the mass annual slaughter becomes nothing more than a statistic, to be conveniently forgotten.
It is high time a world code were created to reduce this senseless waste of human life. With regard to driving, the laws of some countries are notoriously lax and even the strictest are not strict enough. A code which was universally accepted could only have a dramatically beneficial effect on the accident rate. Here are a few examples of some 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 stringent annual tests for safety. Even the smallest amount of alcohol in the blood can impair a person’s driving ability. Present drinking and driving laws (where they exist) should be mad much stricter. Maximum and minimum speed limits should be imposed on all roads. Governments should lay down safety specifications for manufacturers, as has been done in the USA. All advertising stressing power and performance should be banned. These measures may sound inordinately harsh. But surely nothing should be considered as to severe if tit results in reducing the annual toll of human life. After all, the world is for human beings, not motor-cars.
