A new report says sea ice in the Arctic Ocean is melting more quickly than expected. American scientists say the ice is melting even faster than computer programs had estimated.
Scientists know that climate change has a major effect on the Arctic Ocean partly because sea ice is disappearing. They also know that areas of open seawater are expanding. Such areas are known to take in sunlight and increase temperatures. Scientists say this has helped to cause the loss of the Arctic’s ice cover.
For the study, the American scientists compared eighteen computer programs with observations made by satellites and other instruments. The Intergovernmental Panel on Climate Change used the computer programs to prepare its 2007 estimates of climate change.
The computer programs gave estimates of the amount of ice in the Arctic Ocean in the month of September. September is when the Arctic has the least ice, after the warm, summer months. The computer estimates suggested an ice loss of two and a half percent for every ten-year period between 1953 and 2006.  
Newer studies of the Arctic have used information gathered by aircraft, satellites and ships. This information showed a loss of September ice cover of almost eight percent for every ten-year period between 1953 and last year. This means the ice is disappearing about thirty years faster than the computer programs estimated.
The scientists say the programs might not have recognized the full effect of increased carbon dioxide and other gases in Earth’s atmosphere. They say their study suggests the gases may have more of an effect than had been thought.
小題1:It is reported that sea ice in the Arctic Ocean is melting more quickly than expected mainly because _________.
A．climate changeB．sea ice’s disappearance
C．seawater’s expansionD．the loss of the Arctic’s ice cover
小題2: How did the scientists draw the conclusion that sea ice in the Arctic Ocean is melting more quickly than expected?
A．The scientists have been observing the Arctic Ocean for many years.
B．The scientists have compared the computer programs with observation made by satellites and other instruments.
C．The scientists have figured out many numbers with the help of computer.
D．The scientists have found that the seawater take in sunlight and increase temperatures.
小題3:If the ice melts at the present speed, by the end of this century the ice loss in the Arctic Ocean will be _________ according to newer studies.
A．22.5%B．35%C．72%D．100%
小題4:Which of the following is TRUE according to the passage?
A．The figures of the computer estimates are wrong.
B．Scientists study climate change through studying sea level.
C．Newer studies show gases may have more effect on sea ice in the Arctic Ocean.
D．The ice is melting even faster than satellites have estimated.

OSLO — Excited with pride, Norwegians sang in the streets of Oslo on Sunday, celebrating Norway’s National Day and the country’s Eurovision Song Contest victory.
Hundreds of Norwegians sang along to Alexander Rybak’s winning song Fairytale as they walked in the country’s traditional National Day parade (游行) celebrating the Norwegian constitution.
Alexander Rybak — called “Alexander the Great” by the Norwegian media — won a great victory in the Eurovision Song Contest (ESC) by gaining the most votes in its 53-year history in Moscow on Saturday.
Alexander has played violin and piano since he was five years old, and he also composes his own music and sings. In 2006 he won the Norwegian talent show Kjempesjansen with his own song Foolin. Alexander has performed with one of the world’s most celebrated violinists, Pinchas Zukerman, won the Anders Jahres Culture Price and has been the concertmaster for Norway’s largest symphony orchestra (交響樂隊) for youths, Ung Symfoni.
Norwegian Prime Minister Jens Stoltenberg said there was clearly something special about the 23-year-old and his folk music. “This is a phenomenal performance by a young and talented musician,” Stoltenberg said in a statement.
Rybak is expected to draw a large crowd of fans to Oslo’s Gardermoen airport when he arrives next Sunday, after having invited all his countrymen from the stage in Moscow.
With Rybak’s win, Norway will host next year’s Eurovision finals, a show that reaches a television audience of over 100 million people. Norway’s Minister of Culture, Trond Giske, promised that Norway would put on a splendid show next year but without spending as much as Moscow, which spent 24 million euros this year. “I don’t think that is necessary,” he told national broadcaster NRK.
The win was Norway’s third. The Nordic country also won the Eurovision Song Contest in 1985 and 1995.

Sydney 2005-01-01 08:33 --- mother of two, Jillian Searle, had to choose between her children when she made a life-or-death decision.
Swept up by mountainous tsunami（海嘯）waves at a Thai resort ( 旅游勝地), she couldn't hold on to both her young sons and survive. Fighting to stay above the waters, she had to choose which one would have to take his chances in the swirling torrent ( 漩流 ).
“I knew I had to let go of one of them and I just thought I’d better let go of the one that's the older,” she told Sky News Television in a report broadcast on Thursday. She said she was accompanied by the two boys, Lachie, 5, and two-year-old Blake, and their father, Brad, who had watched the drama helplessly from their first-floor hotel room, when the waves struck. “and I was screaming, trying to find him, and we thought he was dead,” she told reporters on arrival back in Australia.

His wife Vicki and son Jake looked on in horror from a hotel balcony (陽臺) as he crashed towards the shore. Luckily, he stayed atop his board until he reached the hotel, jumped off and got to safety as the ocean rolled back to feed a much larger tsunami wave on its way.

My children go to a primary school where they are not allowed to play football in the playground for fear that a child might be hurt. Besides, now the school says there must be no homework because the local secondary school can't keep up with the amount of homework given in the primary school. Can the school do this?   Puzzled Dad
It can't if enough parents do something about it. It is not just schools. We live in a society which wishes to get rid of risk. However, schools should have a little common sense and courage.

China news, Beijing, Feb. 9 – Housing price in China has always aroused heated discussions among property developers（房產(chǎn)開發(fā)商）and ordinary Chinese. To many property developers and local government officials, housing price in China is still low compared with many developed countries. However, the average housing price in the United States is only 8,000 yuan per square meter, while in China, it is even higher than in the United States. This shows that there are some bubbles(泡沫) in Chinese real estate market, the International Finance News reported.
Although the average price of residential houses in the United States, after converted（轉(zhuǎn)換）to Renminbi, is about 8,000 yuan per square meter, the houses in US are not sold in terms of building area, as most Chinese property developers do when they sell their houses. If US property developers sell their houses according to the building area, then the housing price will be even lower than 8,000 yuan per square meter. In most big Chinese cities, such as Beijing, Shanghai, and Shenzhen, houses are sold a t a price even higher than those in the US.
The high housing sales price in large cities in China proves that Chinese real estate（房地產(chǎn)）market does have some bubbles. Moreover, Chinese houses can not be compared with houses in US in terms of building quality, environment and supporting facilities. Furthermore, it should be noted that American people’s average income is several dozen times higher than that of Chinese people. How can the Chinese afford to buy a house which is even more expensive than that sold in US?
At the beginning of 2007, Chinese government issued a set of policies that aimed to benefit the public. Now in order to reduce the high housing prices, the government can regulate (控制) the real estate market by raising tax on property industry and controlling the release of loans（貸款）and lands to property developers. At the same time, the government should allow people to build more houses through various fund-raising channels, such as funds collected from buyers or raised by working units. By applying these multiple means, it is expected that the high housing prices can be lowered.
小題1:What is the average housing price per square meter in China?
A．8000 yuan.B．10000 yuan.C．7000 yuan.D．it’s not mentioned here.
小題2:Which of the following does NOT support the idea that the average housing price in China is  even higher than in the United States?
A．Chinese houses can not be compared with houses in US in terms of building quality, environment and supporting facilities.
B．American people’s average income is several dozen times higher than that of Chinese
people.
C．The houses in US are not sold in terms of building area, as most Chinese property
developers do when they sell their houses.
D．There population who need houses in China than in the United States.
小題3:How many measures are mentioned in the last paragraph in order to reduce the high housing  prices?  
A．Four. B．Three. C．Tow. D．One.
小題4:What is the main idea of this passage?

prevent it.
B．There are some bubbles in Chinese real estate market.

As an effect of the high fuel prices spent on bus transportation, some American schools are changing to a four-day week. That means longer days instead of the traditional Monday through Friday schedule.
Having been approved for three years and beginning in the fall, students in the Maccray school district in Minnesota will be in school from Tuesday to Friday. Each school day will be 65 minutes longer. Officials say the district expects to save about sixty-five thousand dollars a year in transportation costs.
In new Mexico, the first school district changed to a four-day week in 1974 because of the Arab oil boycott(抵制). Now, 17 out of 89 districts use it.
In Custer, South Dakota, students have been going to school four days a week since 1995. Superintendent(主管人)Tim Creal says the change has saved about one million dollars over just the past eight years. He sees other benefits, too. Students get more instructional time, and activities that used to take up class time are now held on non-school days. He says that in the future, the growth of online classes could make it possible to require even fewer days in school. High fuel prices are driving college students to take more online classes.
A four-day school week sounds like a great idea for students and teachers, but working parents may have to pay for child care for that fifth day.
1. According to Tim Creal, what makes it possible to have even fewer days in school?
A. The increasing number of private tutors.
B. The development of teaching methods.
C. The increase in the number of online classes.
D. The growth in the income of Americans.
2. It can be learned from the passage that______
A. students will be in school from Monday to Tuesday.
B. four-day week was first carried out in South Dakota.
C. Maccray will save one million dollars every year.
D. Minnesota state has approved the four-day week plan.
3. The passage is mainly about______
A. some school’s four-day week plan    B. districts using a four-day week.
C. how to save on transportation fees.   D. expense of school transportation.
