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.

One of the most famous buildings in the United States is Carnegie Hall, the home of classical and popular music concerts in New York. Carnegie Hall is known not just for its beauty and history, but also for its amazing sound. It has been said that the hall itself is an instrument. It takes the music and makes it larger than life.
Carnegie Hall is named after Andrew Carnegie, who paid for its construction. He was a wealthy man who also gave a lot of money to schools and public libraries. Construction on Carnegie Hall began in 1890 and the official opening night was on May 5, 1891.
The hall was owned by the Carnegie family until 1924 when it was sold to Robert E. Simon. The building became very old and in 1960, the new owner made plans to destroy it and build an office block. Isaac Stem led a group of people who fought to save Carnegie Hall and finally, the city of New York bought it for $5 million. It was then fixed up between 1983 and 1995.
In 1986, people realized that Carnegie Hall had never kept proper records of its history. Advertisements and stories in newspapers about how Carnegie Hall needed help to recover its history led people to send in old concert programmes and information from all over the world. Over 12,000 concert programmes were received and with these it was possible to make a proper record of Carnegie Hall’s concert history.
Carnegie Hall is actually made up of several different halls, but the Main Hall, now called the Isaac Stern Hall, is the most famous. Most of the greatest performers of classical music since the time the hall was built have performed in the Main Hall, and its reception areas are decorated with signed photographs of these musicians. The hall itself can hold an audience of 2,804 in five levels of seating. Visitors to the top level have to climb up 105 steps to get there!
Because the best and most famous musicians of all time have played at Carnegie Hall, it is the dream of most musicians who want to be great to play there. This has led to a very old joke which is now part of Carnegie Hall’s history. Question: “How do I get to Carnegie Hall?” Answer: “Practise, practise, practise.”
What do music lovers expect in Carnegie Hall?

A．Musical concerts presented by first class performers.

B．Exhibits and photographs of historical events.

C．Musicians practicing for opportunities to play.

D．People dancing merrily at parties.

What is the correct order of the following events?

During the twentieth century, cars, electric lights, space travel and amazing advances in medicine changed people’s lives. So what might this new century bring? There are hundreds of predictions flying around — let’s have a light-hearted look at some of them.
In a recent UK survey, teenagers were asked to make predictions about the year 2020. One of the most common predictions was that school uniforms won’t be around. They also predicted that both girls and boys will wear make-up more often, and more than 75% of men will wear skirts regularly. My dad is 65 next Saturday — I think I’ll buy him a skirt as a birthday present and tell him he’ll soon be in fashion!
Other predictions involve changing roles of men and women. By 2017, some people say that single men of working age will form more than 10% of all families. It is also predicted that washing powder advertisements will include more men because more of them will do housework. I’ll tell that to my husband when he gets home and see how keen he is to wash the dishes!
Many predictions are about crime and safety problems. Some people think that crime will improve and the world will become a more peaceful place. Others believe that crime is going to worsen and that people will stay at home becoming completely dependent on the Internet for shopping and work. It is also predicted that you will need an electronic card to get into parks as parents demand safe play areas for their children. This is old news for me --- our local government is going to introduce one this summer.
Technology is predicted to play an even more important role in our lives in the future. Some parents might have cameras at home so they can keep an eye on their children while they are out. Quick, kids, turn off the TV and do your homework!
Here’s another prediction. Researchers have concluded that cultural activity may add years to your life. The cinema, theatre and concerts may give us a longer life because they encourage strong feelings. Well, we’re watching Bridget Jones’ Diary this Friday night. Will that help us live longer?
Let’s finish up with my favourite prediction. In the future, elderly people are going to make up a larger proportion of the world’s population than ever before. In Britain, an estimated 100,000 people now in their thirties may live to be 100. And that includes me! I’ll have a big, big party, I promise!

“Everybody in this city wants a car, and I’m no exception. A car brings with it the freedom to travel”, said a friend of mine while reading a car magazine. I might not agree with him, but no doubt he was speaking for a rapidly growing number of middle-class Chinese. While it is true that all the waiting, walking, being part of a crowd, and sweating, are somewhat unpleasant, there are many problems which can arise when our lives rely too much on this invention.
First of all, in terms of polluting the environment, driving a car is the worst act an average person can commit. Beijing now finds itself at the top of the list of the most polluted capital cities in the world with Mexico City in the second place. Research also shows that by 2010 around 90% of total pollutants in Shanghai have come from cars. These pollutions are extremely dangerous to our health. They can damage the lungs, cause cancer, and damage the brain.
Apart from environmental problems, relying too much on cars also creates social problems such as traffic jams, road accidents, and noise pollution. The jeeps that proudly drive through the Hutongs in Beijing as if they are in a race often annoy me, and to make it worse, these drivers seldom respect cyclists.
Of course, we cannot forget the convenience that cars bring us when we need to travel far, but I often find it faster to cycle from one place to another within the city of Beijing, especially with the growing traffic jams.
Since people travel further and more frequently than before, cars will certainly be important in the future. At the same time, however, let us work hard to make sure that this invention brings us a more convenient lifestyle rather than trouble and disease. Let us make good use of cars.
What is this passage mainly about?

A．Environmental problems.

B．Traffic jams in Beijing.

C．Problems brought about by cars.

D．Benefits of using cars.

Barbie(芭比娃娃)，believe it or not，is 50 this year and she's still as popular as ever.A doll is a doll，but Barbie illustrates how，over the last five decades，women have become a standard for judging what freedom really means. How women are treated in different countries tells you a lot about the politics and culture of where they live.
The doll that every little girl wants enables young children to test their possibilities in role playing，giving them a glimpse of what they might be when they grow up，whether to be frivolous or serious (or both)．
But in many countries that's not an option. In Saudi Arabia，where woman can't drive or go out publicly unless covered，Barbie is banned. They think Barbie dolls are offensive to Islam(伊斯兰教) and a threat to morality.
In America，she represents the swiftly changing roles of women. Barbie is fun to tease but she's as American as miniskirts_and_pantsuits in her flexible identities and her “growth” from model to astronaut.
Barbie inspired a dollrevolution movement. When a Teen Talk Barbie was programmed electronically to say “Math class is tough”，she was criticized by a national women's group and was regarded as a bad stereotype. Some of her critics also say she's a bad influence because she's too thin and encourages anorexia，that she has run through too many stereotypes(固定模式)，and that she lends too much significance to the fantasy stages of child's play.
In some Muslim countries, substitute Barbie dolls have been developed that promote traditional values，with their modest clothing and profamily backgrounds. They are widely seen as an effort to resist the American dolls that have flooded the market.
Toy seller Masoumeh Rahimi welcomed the dolls，saying Barbie was “foreign to Muslim culture” because some of the dolls have little clothing. She said young girls who play with Barbie，could grow into women who reject Muslim values. “I think every Barbie doll is more harmful than an American missile，”Ms. Rahimi said.

A．these are the only clothes a doll should wear

B．these are very traditional American clothes for women

C．there are a range of different life options available for women

D．readers should wear these clothes more often

The underlined word “anorexia” (in Paragraph 5) most probably means“________”．
