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.
【小题1】It is reported that sea ice in the Arctic Ocean is melting more quickly than expected mainly because _________.

Are you afraid of change? Whether it is you personally or the working/living environment around you that changes, change will happen, it’s one guarantee I can give you and if you want success you need to make changes too.

   Throughout the history of mankind changes have happened and they will continue to do so until the end of time. I do not think I need give you a list of any of these events they are obvious to us all.

    Because some of us resist change, because we are afraid of the unknown factors that change may bring into our lives.

    Stop resisting and the changes will happen automatically, that is what happened to me when I started using hypnosis(睡眠状态) and mediation (沉思)to help me come to terms with the changes I needed to make to get out of Going Nowhere Land. I honestly believe that if I had not lost my fear of change when I did that there is absolutely no way that I would be enjoying life and the success I am having as much as I do at this moment in time.

     My intention is to carry on enjoying life to the full and to successfully help others to do the same and if that means making even more changes to my life, as it surely will, then bring them on and let’s get started.

    It does not matter if you start off making small changes like getting up early so that you can share breakfast with your loved ones, take some exercise or meditating before going to work, start making those changes now. By getting into the habit of making changes, you will accept change into your life, you will begin to change more of your old habits into new and better ones and even enjoy the feeling that making those changes brings and the success that comes with them.

BEIJING — After a night of wining and dining with 50 of China’s richest people, Warren Buffet and Bill Gates told the journalists on Thursday that the biggest difference between eating with Chinese tycoons(企业界大亨) and Western ones was the food.
“I was amazed last night, really, at how similar the questions and discussions and all that were to those in the dinners we had in the U.S.,” said Mr. Buffett.
Mr. Buffett and Mr. Gates, two of the best known Westerners here, announced in September, 2010 that they planned to invite 50 wealthy Chinese tycoons to dinner in Beijing to encourage philanthropy(慈善事业) among China’s new rich.
On Thursday, the two men pronounced the dinner a great success, saying that two-thirds of those invited had shown up, and that more than half of them had offered their own ideas on how Chinese philanthropy should work.
The guest list wasn’t made public, but the Chinese news media reported that it included Jet Li, the movie star; Niu Gensheng, the founder of a Chinese dairy business; and Pan Shiyi and Zhang Xin, who control the SOHO China real estate(房地产) empire.
As with four earlier dinners held in the United States, Mr. Buffett and Mr. Gates said, no one at the Beijing event was asked to donate money or to promise to engage in charity. “Bill and I won’t be calling anybody. What happens in China will depend on what the Chinese people feel about a project of this sort,” said Mr. Buffett.
China is widely reported to be second only to the United States in the number of dollar billionaires. Mr. Gates and Mr. Buffett said the nation was unique because its wealthy class had arisen almost wholly in the past 30 years, so the philanthropic practices established among European and American dynasties are new here, and open to change.
The two said the dinner wasn’t a long planned matter, but an offshoot of a trip that Mr. Buffett had already scheduled to Guangdong and Hunan Provinces, where BYD Company, a maker of clean-energy automobiles, has factories. Mr. Buffett’s company, Berkshire Hathaway, holds a 10% stake(股金) in the company.
But Mr. Gates suggested that their philanthropic trip wasn’t yet over. “We may do an event in India,” he said.
【小题1】What is the text mainly about?

【小题3】We can learn from the text that __________.
A.China has the largest number of dollar billionaires in Asia
B.many people have promised to donate money at dinner
C.Beijing will be the last stop of their philanthropic trip
D.the Chinese news media published the complete guest list of the dinner
【小题4】The underlined words “an offshoot” in Paragraph 8 can probably be replaced by “________”.

Like distance runners on a measured course,all of us will move through time in a roughly predictable pattern.
In the first stage of our lives,we develop and grow, reaching toward the top of physical vitality(活力).
After we grow up,however, the body begins a process of gradually wearing out.
A new awareness of physical fitness may help lengthen our years of health and vitality,yet nothing we do will work to stop the unavoidable force of aging.
Most of the changes of aging take place deep inside the body.The lungs become less able to take in oxygen.Powerful muscles gradually lose their strength.The heart loses power and pumps less blood.Bones grow easier to break.
Finally, we meet a stress,a stress that is greater than our physical resistance.Often,it is only a minor accident or chance infection(a disease caused by virus),but this time,it brings life to an end.
In 1932,a classic experiment nearly doubled the lifetime of rats,simply by cutting back the calories in their diet The reason for the effect was then unknown.
Today, at the University of California at Berkley, Dr.Paul Seagle has also greatly lengthened the normal lifetime of rats.The result was achieved through a special protein limited diet,which had a great effect on the chemistry of the brain.Seagle showed that within the brain,specific chemicals control many of the signals that influence aging.By changing that chemical balance,the clock of aging can be reset.
For the first time, the mystery of why we age is being seriously challenged.Scientists in many fields are now making striking and far-reaching discoveries.
An average lifetime lasts 75 years,yet in each of us lies a potential for a longer life.If we could keep the vitality and resistance to disease that we have at age twenty, we would live for 800 years.
【小题1】What does the underlined word “it” refer to?

A.Physical vitality.B.Stress.C.Aging.D.Physical resistance.
【小题2】Which of the following is not a change of aging?
A.People gradually lose their muscle strength.
B.Bones tend to break more easily.
C.The heart loses power and pumps less blood.
D.The lungs become unable to take in oxygen.
【小题3】The author believes the following except that     
A.human's life pattern is predictable
B.physical fitness can't stop the force of aging
C.human's lifetime will last longer than 75 years
D.all of the changes of aging take place deep inside the body
【小题4】How did Dr.Paul Seagle lengthen the lifetime of rats in his experiment?
A.By keeping their physical fitness.B.By cutting the calories in their diet.
C.By resetting their clock of aging.D.By limiting the protein in their diet.
【小题5】What is probably the best title for the article?
A.Two Great Experiments
B.The Mystery of Human Life
C.The Breakthrough in the Study of Aging
D.Ways to lengthen Human Life
