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.

Karen,grown up in a very traditional family in the western United States,maintained high moral(道德的) standards throughout her youth.In 1984,at the age of 23,she married Bill.They were blessed with two children,a boy and a girl.
By 1991 their love had deepened,and they were happy.Later that year,Bill developed a white spot on his tongue.He visited a doctor.
One day shortly after that,Bill called Karen to sit beside him.He said with tears in his eyes that he loved her and wanted to live forever with her.The doctor suspected that he had been infected with HIV,the virus that leads to AIDS.
The family was tested,Bill and Karen’s results were positive.Bill had become infected before he met Karen;then he passed the virus on to Karen.The children’s results were negative.Within three years,Bill was dead.“I don’t know how to express what it is like to watch the once handsome man you love and intend to live with forever dying slowly.I cried many nights.He died three months short of ten years of our marriage,”says Karen.Though a doctor told Karen that she would soon follow her husband into death,she is still alive.The infection has progressed to the early stages of AIDS.
Karen is but one of about 30 million people now living with HIV/AIDS,a figure larger than the combined populations of Australia,Ireland and Paraguay.According to one UN report,Africa has 21 million of these victims.By the turn of the century that number could reach   40  million and the disease will bring on the greatest disaster in human history.Of the world’s sexually active adults aged 15 to 49,1 in 100 has already been infected with HIV.Of these,only 1 in 10 realizes that he or she is infected.In some parts of Africa,25 percent of the adults are infected.
Since the beginning of the spread of AIDS in 1981,about 11.7 million people have died of it.It is roughly calculated that in 1997 alone,about 2.3 million people died of it.Nevertheless,there are fresh reasons for optimism in the battle against AIDS.During the past few years,there has been a drop in new AIDS cases in wealthy nations.In addition,promising drugs hold out hope of better health and longer life.

The HOPE IS A GAME--CHANGER PROJECT will deliver unbreakable soccer balls to kids who, all too often, see things horrible, broken and not survive the simplest of circumstances. The project started taking form well before anyone knew where it would lead –which is to test the power of like-minded people working together to turn inspiration into action.
Four years ago Bobby was in Rwanda offering help to the people there and taking photos of a child soldier named Moise with his “soccer ball”,which was a pile of rubbish tied together with a string. This “ball” was the only thing Moise could call his own --- no family, no home, no place to go. Forced to fight in the Congo and having killed three people at the unbearably young age of seven, the boy’s spirit was broken. And Bobby knew, as he took one photo after the next, that he’d never forget him. In fact, he returned the following year to tell Moise he had stayed deep within his heart ---but he was gone.
I recently helped Bobby launch his new book The Power of the Invisible Sun which features a photo of Moise, his ball, and kids from war-torn areas around the world. All of his earnings go towards the HOPE IS A GAME-CHANGER PROJECT for the kids he visited over the past decade. They caught the emotional landscape from heartbreak to joy, but share the undeniable longing for recovery and hope.
Bobby and I share the unchangeable belief that delivering hope is really a game-changer, especially to a child. We believe that each indestructible ball will come to represent a lasting symbol of hope. A light no matter how small---The Power of the Invisible Sun.
This holiday season, I ask you to think about whether you are doing enough to help someone else in the world. Or as Bobby likes to put it, consider “taking a concrete baby step”, which added together, can create transformational change. It’s my great hope that the HOPE IS A GAME-CHANGER PROJECT will change the lives of children the world over --- one book, one ball at a time.
小題1:In the first sentence of the passage, the writer implies that        .
A.kids live an unsafe life in parts of the world
B.the balls sent to kids should be of good quality
C.young kids can not overcome the difficulties
D.kids intend to break their toys into pieces
小題2:The purpose of The HOPE IS A GAME-CHANGER PROJECT is to        .
A.send ball gifts to kids in poor countries
B.collect money to help kids in need
C.comfort kids in war-torn areas
D.offer kids help to change their lives
小題3:How may Bobby feel about Mosie?
A.He was very proud of Mosie’s bravery.
B.He felt sorry for Mosie’s ruined childhood.
C.He thought money could solve Mosie’s problem.
D.He felt happy to tell him what was in his heart.
小題4:Which of the following about Bobby’s new book is TRUE?
A.It earned a lot of money to help kids like Mosie.
B.The photos inside reflected the kids’ hopeless life.
C.Its title shows the author’s belief to change the world.
D.It changed the life of the kids recorded in the book.
小題5:The underlined part in the last paragrph probably means        .
A.starting the first step as a baby does
B.taking an active action from now on
C.making great changes step by step
D.doing some small but good deeds

Once in a blue moon there is one on New Year's Eve. Revelers ringing in 2010 will be treated to a so-called blue moon. According to popular definition, a blue moon is the second full moon in a month. But don't   1  it to be blue - the name has nothing to   2  the color of our closest celestial(天體) neighbor.
A full moon   3  on December 2. It will appear again on Thursday in time for the New Year's countdown.
"If you're in Times Square, you'll see the   4  moon right above you. It's going to be that brilliant," said Jack Horkheimer, director emeritus of the Miami Space Transit Planetarium and host of a weekly astronomy TV show.
The New Year's Eve blue moon will be   5  in the United States, Canada, Europe, South America and Africa. For partygoers in Australia and Asia, the full moon does not show up  6  New Year's Day, making January a blue moon month for them.
However, the Eastern Hemisphere can celebrate with a partial lunar eclipse(月蝕) on New Year's Eve when  7  of the moon enters the Earth's shadow. The   8  will not be visible in the Americas.
A full moon occurs   9  29.5 days, and most years have 12.  10 , an extra full moon in a month - a blue moon - occurs every 2.5 years. The   11  time there was a lunar double take was in May 2007. New Year's Eve blue moons are rarer, occurring every 19 years. The last time was in 1990; the next one won't  12   again until 2028.
Blue moons have no astronomical   13   , said Greg Laughlin, an astronomer at the University of California, Santa Cruz.
"`Blue moon' is just a   14  in the same sense as a `hunter's moon' or a `harvest moon,'" Laughlin said in an e-mail.
The popular definition of blue moon   15  after a writer for Sky & Telescope magazine in 1946 misunderstood the Maine Farmer's Calendar and marked a blue moon as the second full moon in a month. In fact, the calendar   16  a blue moon as the third full moon in a season with four full moons, not the usual three.
Though Sky & Telescope corrected the  17  decades later, the definition caught on. For purists(語言純正癖者), however, this New Year's Eve full moon doesn't even qualify as a   18  moon. It's just the first full moon of the winter season.
In a tongue-in-cheek essay   19  on the magazine's Web site this week, senior contributing editor Kelly Beatty wrote: "If skies are clear when I'm    20 celebrating, I'll take a peek(瞇著眼睛看) at that brilliant orb(天體) as it rises over the Boston skyline to see if it's an icy shade of blue. Or maybe I'll just howl."

You are a German living in Berlin. One day you’ re walk¬ing down the street, minding your own business, when sudden¬ly a stranger comes up with a smile on his face. After stopping you, he holds a small electronic device (裝置) close to his face and speaks slowly into it, saying, in English," Can you tell me where I can buy some sauerkraut?" What should you do? (a) Run away; (b) Call the police; or (c) Listen closely for the device to say in German," Konnen Sie mir bitte sagen, welches sauerkraut haufen kann?"
The most proper answer would be (c) because the person in front of you is only a tourist trying to enjoy himself. The de¬vice is said to be the world’s first portable(便攜的) translator — a hand-held microcomputer that at the same time translates one spoken language into another. The four-pound, battery-op¬erated product is called the Voice, and it is the invention of Advanced Products and Technologies, an American electronics company. When the Voice is introduced in the Unite States in late April — at a price of (1,500 — it will be used to trans¬late spoken English into Italian, German, French and Span¬ish. The product comes with separate cartridges(盒式存儲器) for each of the four languages, which can be changed when the user travels from one country to another. It will be sold in Eu¬rope soon after the US introduction, with cartridges that trans¬late Italian, German, French and Spanish into English.
The Voice uses a microchip(微型集成電路片) to trans¬late languages. It is Started by voice command and produces voice output through a built-in speaker. When the user makes a statement or asks a question, the Voice immediately repeats what has been said in another language.
1. The device held by the stranger is probably a kind of________.
A. a two-way radio                      B. language translator
C. easily-carried speaker                     D. a multi-functioned computer
2. What does the last sentence of the first paragraph mean?
A. Can you tell me where I can buy some sauerkraut?
B. Can I ask for some information from the police?
C. Would you like to try my device?
D. Would you not run away if I ask you where to buy some sauerkraut?
3. When the stranger says," Can you tell... sauerkraut?" he is ________.
A. learning German from his device
B. asking you the way to the sauerkraut shop
C. making fun of you with his device
D. testing his device for fun
4. Which of the following is not mentioned in the text?
A. The price of the hand-held microcomputer.
B. The function of the product Voice.
C. The producer pf the small electronic device.
D. The number of the device sold to the European coun¬tries.

The Galapagos a far-away archipelago(群島) and largely untouched by man, is now facing a problem. Its local people, who live on the island of Santa Cruz, want to develop the business and tourist potential(旅游資源)of the island. Recently, they are locked in a bitter struggle with the naturalists who work at the Charles Darwin Centre, also on Santa Cruz. The naturalists want to protect the island’s wildlife which is already suffering as a result of human activity.
The animals’ great threat used to be sailors who, hundreds of years ago, robbed the islands for food. They wiped out about 250,000 Giant Tortoises. For example, on Pinta, one of the smallest islands, there are no Giant Tortoises left at all. The last survivor, an 80-year-old Giant Tortoise called Lonesome George, lives under the protection of naturalists at the Darwin Centre.
Today, the island’s animals are no longer hunted for food. But other dangers have replaced the threat from sailors. Goats, for example, introduced over the years by man, have gone wild. With no natural enemies, their number has reached 10,000 on the largest of the Galapagos islands, Isabella. They are eating huge quantities of plants, and robbed the remaining Giant Tortoises of food. The problem is now so bad that the National Park Service has hired hunters to kill the goats in order to save the Giant Tortoise from dying out.
小題1:Today, you can find the Giant Tortoises on the island of _______.
A.Santa Cruz B.PintaC.IsabellaD.Galapagos
小題2:Which of the following shows the right relationship between the Galapagos, Isabella, Pinta and Santa Cruz?
A.The Galapagos>Pinta>Isabella>Santa Cruz
B.Isabella>Santa Cruz>the Galapagos>Pinta
C.The Galapagos>Isabella>Santa Cruz>Pinta
D.Isabella>the Galapagos>Pinta>Santa Cruz
小題3:We can learn from the article the greatest danger to the Giant Tortoises is from________.
A.sailorsB.huntersC.goatsD.the local people
小題4:From the first paragraph we can infer that _____.
A.the naturalists try to help the local people with their interest.
B.The local people pay more attention to the economic growth than the wildlife there,
C.The animals and plants are of great importance to the local.
D.The naturalists don’t care about the local people at all
