Against the supposition 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 fires 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 the 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 the 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 predicted, 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 __________.

The most important holiday in spring, especially for Christians, is Easter. This Christian holiday is not on the same date every year,but it’s always on a Sunday. It can be any Sunday between March 22 and April 25. Many people celebrate Easter by buying new clothes. Children celebrate by hunting for colored eggs that their parents have hidden around the house. People also give Easter baskets filled with candy and other goodies to one another to celebrate the day.
But the holiday is more than new clothes and good things to eat. On Easter, many people go to church to celebrate Jesus’ resurrection(复活)from the dead. Most people color Ester eggs. Some people hide them. Others just eat them. But no matter what one does with Easter eggs,they are an important Easter tradition throughout the Western world. People from many different cultures celebrate Easter. In both America and Belgium, children look for Easter eggs hidden on lawns and in bushes. In America, children believe the eggs are hidden by the Easter bunny (兔子).But in Belgium, the hidden eggs are supposed to have fallen from church bells. In Bulgaria (保加利亚), red Easter eggs are lucky in churches. Bulgarian families also hit these Easter eggs together to see whose is the strongest. The winner looks forward to good fortune that year. Still dozens of other Easter traditions exist. In parts of Austria,for example,children sing from door to door and are rewarded with colorful eggs.

As the sound of footsteps behind her grew louder, she quickened her pace. She didn’t want to turn around as the memory of that morning’s newspaper headline made her afraid of what she would see: “City Killer Claims Fourth Victim.”
“Why did I stop for a few drinks in the bar after work?” she thought to herself. Now it was dark and the streets deserted. She was alone and a sitting duck.
She felt as if she was walking in the rain. Her clothes were damp from nervous sweat and as each short hot breath hit the night air, it turned to steam, coating her glasses in a thin film so all she saw seemed covered in fog.
The footsteps were closer now. She needed to get off this street. Her eyes began a useless search for an open store or lighted window. Passing a small lane she looked through, for a possible escape route. But the lane was a dead - end and she laughed to herself at the irony ( 具有讽刺意味的事 ).
The sound of a car behind her turning onto the street interrupted her self – pity. Escape was at hand. But as she was about to throw herself onto the road and shout for the car to stop, the car’s headlights cast a shadow that paralyzed ( 使瘫痪 ) her with terror.
It was the footsteps’ owner. The figure was huge and in its raised arm it held what looked like a lead-pipe, no doubt the one that was about to claim victim number five.
The shadow dissolved as the car passed by and disappeared into the distance. She felt a hand on her shoulder. It was all happening as if in slow – motion. She was waiting for her life to flash before her eyes like all those novels said it would – but it didn’t. The only thing she thought of was her dear husband. She recalled phoning him from work that very afternoon and joking about, of all things, the city killer. It was a night full of ironies.
There was a voice talking to her now but she was lost in thoughts of her fate and didn’t respond. The hand then began turning her around. It was surprisingly gentle given what was about to come. She allowed it to guide her without resistance ( 抗拒 ).
She looked up. She recognized the face, but she didn’t know from where. Its mouth was still talking to her but she couldn’t understand. Then she remembered. The face belonged to the foreign looking man who had served her at the bar. She looked down to his hand and saw in it not a lead – pipe but a rolled up copy of a work report she had been correcting in the bar as she drank.
His words suddenly started to register in her brain and she could hear him. “Miss, Miss. Are you OK? You left this in the bar and it looked important so I thought I’d better give it to you.”

1685 was a very good year for German composers. Within the space of a month, two of the greatest were born: Johann Sebastian Bach and George Frideric Handel.
Handel’s father was a barber and surgeon, which sounds like a strange combination today, but back then those occupations went hand in hand. Even though Handel was very interested in music, his father didn’t think that was a good way to earn a living, so he wanted his son to be a lawyer. The story goes that Handel smuggled a quiet piano into the house so that he could practice in secret.
One day, Handel went along when his father went to shave a duke. While his father was working, Handel sat down and played the duke’s organ. The duke was so impressed that he convinced Handel’s father to let his son study music, and Handel finally got to learn how to compose.
Handel soon discovered that what he liked most was opera. In fact, he was so passionate about opera that he even fought a duel (决斗) over it with one of his friends. Since Italy was the place to learn about opera composing, Handel went off to Italy to study. When he got home, he got a job as court composer for a German prince.
Having landed such a wonderful job, Handel immediately asked his boss for time off. He wanted to go to England, where he’d heard that there weren’t nearly enough composers to satisfy the British taste for Italian opera.
After great success writing opera in London, Handel came back to Germany. Then fate played a funny trick on Handel and his boss. The Queen of England died, and it just so happened that the prince Handel worked for was next in line to the British throne ( 王位 ). When he arrived in London as King George, followed Handel, his court composer in Germany.
In addition to serving the King, Handel became one of the most successful opera composers of his time. And he also produced them and traveled all over Europe to hire the best singers. There are stories of battles with rival ( 对手 )opera producers and of fights between rival singers. Handel apparently had quite a temper.
If you ever go to London, look for Handel’s grave in Westminster Abbey, where there’s a wonderful monument to him.

I began to grow up that winter night when my parents and I were returning from my aunt’s house, and my mother said that we might soon be leaving for America. We were on the bus then. I was crying, and some people on the bus were turning around to look at me. I remember that I could not bear the thought of never hearing again the radio program for school children to which I listened every morning.
I do not remember myself crying for this reason again. In fact, I think I cried very little when I was saying goodbye to my friends and relatives. When we were leaving I thought about all the places I was going to see—the strange and magical places I had known only from books and pictures. The country I was leaving and never to come back was hardly in my head then.
The four years that followed taught me the importance of optimism, but the idea did not come to me at once. For the first two years in New York I was really lost—having to study in three schools as a result of family moves. I did not quite know what I was or what I should be. Mother remarried, and things became even more complex for me. Some time passed before my stepfather and I got used to each other. I was often sad, and saw no end to “the hard times. ”
My responsibilities in the family increased a lot since I knew English better than everyone else at home. I wrote letters, filled out forms, translated at interviews with Immigration officers, took my grandparents to the doctor and translated there, and even discussed telephone bills with company representatives.
From my experiences I have learned one important rule: Almost all common troubles eventually go away! Something good is certain to happen in the end when you do not give up, and just wait a little! I believe that my life will turn out all right, even though it will not be that easy.

Parking has long been a major headache for drivers in Shanghai. The Transportation Department is mapping out a new plan for the city’s parking system. There are one million cars on the road in Shanghai but only enough public parking space to provide room for 15 percent of these vehicles. It is no wonder that local drivers get so worried trying to find a place to park.
The city is seeing a rise in private car owners. In March, the city sent out 2,000 private car licenses, the highest number of licenses ever sent out in a month. And prices rose to 14,600 yuan, 500 more than in February. Industry experts say this suggests that local people have a strong, active interest in buying cars.
By the year 2020, the number of automobiles in Shanghai will probably reach two million. If one parking lot is for each car, then a lot of parking space should be built for these vehicles.
Downtown Shanghai is most short of parking space. However, experts point out that simply building more parking lots in downtown areas is not practical and doesn’t provide an ideal solution. The idea of “ Park & Ride” system has been suggested. This means that drivers can leave their vehicles in car parks nearby subway or bus stations and ride public transport to go downtown. Based on this idea, the city will limit the number of parking lots in downtown areas and demand higher parking fees but build more parking areas near main subway and bus stops.
72.The underlined phrase “ mapping out ” in the first paragraph means __________.
A. making B. arguingC. controllingD. inspiring
73. About __________ drivers can find places to park their cars in Shanghai now.
A. 850,000 B. 1,000,000C. 150,000D. 2,000,000
74. What does the second paragraph mainly tell us ?
A. The city sent out more private licenses in February.
B. Less and less people bought cars in March.
C. The city sent out less private licenses in March.
D. More and more people are going to buy cars.
75. According to the idea of a “ Park & Ride ” system, the city will __________.
A. send out more private car licenses
B. build more parking lots near bus stops
C. encourage people to buy more cars
D. build more parking areas in downtown
