One of the biggest ideas in computer technology is cloud computing. The system is changing the way information is kept. It uses a group of computers or servers to store information instead of one. The data floats around like clouds instead of being saved on any computer. It means computers can be smaller than ever and store practically unlimited amounts of information. No longer are bulky computers needed because all the information is in the clouds.
So when will cloud computing start affecting the way you use computers? You may not have noticed, but it already has. Facebook, Amazon, Twitter and many other sites all run on cloud computing. Cloud computing is really useful. You can use it to access the same file at work at home or in other countries on different computers. There may even be environmental benefits, too. Gmail, which uses cloud computing, says that the system saves a lot of energy.
However, potential problems do exist such as losing information and not being able to access certain files when the internet is down. Also, some companies charge fees for their cloud computing services. Another major problem is security. If all your Information is out there in the cloud and not safely stored on your own computer or laptop, it may be possible for other people to access it. More and more of our personal information is in danger of being stolen. Therefore, it is important to be careful and to find ways of making the information secure.
More and more companies are starting up and offering cloud computing. Will the company be reliable? What will happen to your data if the company goes out of business? There are real worries. Even so, for those interested in computing technology, one thing is for certain ---the future in the clouds is going to be very exciting.

Are you wondering whether it’s worth going for a little jog? Don’t hesitate, and get your sports shoes on. A new study shows that proper running lowers the risk of death before the normal time.
In an analysis of 14 previous studies from the US and Denmark, the group of researchers from institutes in Australia and Finland concluded that increasing running participation would probably lead to substantial improvements in population health and longevity. The studies involved 232,149 participants over time periods ranging from 5. 5 to 35 years.
On the whole, people running any distance were associated with a 27% lower risk of death from all causes than those who did not, the study shows. Running was also related with a 30% and 23% lower risk of death from cardiovascular(心血管的)disease and cancer, respectively.
Previous studies had concluded “inconsistent findings” about whether running could lower the risk of premature death, according to the researchers. Lead researcher Jim White, a professor at Victoria University in Melbourne, told CNN: “Our recent findings may encourage physically inactive individuals to take up running and those who already run to keep on doing it.”
He added that doctors may be encouraged by our findings to promote running as a part of “lifestyle medicine”. In their paper, which will be published in the British Journal of Sports Medicine, the researchers say health professionals are sometimes wary of promoting running because vigorous(剧烈的)use of it has been linked with sudden heart death.
Jim and his team deny this by noting that the benefit of running outweighs the risk. However, they did say advice should be given on a case-by-case basis, as running might not be appropriate for everyone. Although running has a clear health benefit, the researchers point out that higher “doses” of running may not reduce the risk of premature death further. According to the WHO’s guidelines, adults aged between 18 and 64 should take 150 minutes of gentle exercise or 75 minutes of vigorous exercise each week.

3.What does the underlined word “wary” in paragraph 5 mean?
A.Certain. B.Tired.
C.Cautious. D.Confident.
4.What’s the last paragraph mainly about?
A.The risk of exercising vigorously.
B.The reasons why people should keep running.

In the winter of 1910, Dr. Wu Lien-Teh stepped off a train in the northern Chinese city of Harbin. He was there to solve a medical mystery, at great personal risk. Over the past few months, an unknown disease had swept along the railways of northeast China, killing 99.9% of its victims. The Qing Imperial court had sent the Cambridge-educated Dr. Wu north to stop the epidemic.
When Dr Wu arrived in Harbin on Christmas Eve, 1910, he carried little in the way of medical instruments and had only one assistant. One of Wu' s first acts upon arrival was to set up special quarantine(隔离) units and to order lockdowns to stop infected persons from traveling and spreading the disease. He had teams check households for possible cases, and even managed to convince authorities to completely close the railways in the early weeks of 1911. Of particular concern was the upcoming Chinese New Year holiday, which had become a great annual migration of people traveling across the country to see their families.
Thanks to Dr. Wu's efforts, the number of plague victims began to die down, and by March 1, 1911, the epidemic was fully contained. The pneumonic (肺炎的) plague outbreak of 1910-1911 lasted nearly four months, affected five provinces and six major cities, and accounted for over 60,000 deaths. It is clear that without the brave and decisive actions taken by Dr. Wu, it could have been much worse. Had the epidemic gone unchecked, allowing holiday rail passengers to spread the disease to the rest of China could have meant a catastrophic loss of life and possibly a global health crisis.
In April 1911, Dr. Wu chaired an International Plague Conference in Shenyang, attended by scientists from 11 counties including the United States, Great Britain, Russia, Japan and France. They praised Dr. Wu for his handling of the 1910-1911 outbreak. For a time, Dr. Wu was the world's most famous plague fighter, a title be defended in a malaria epidemic in China in 1919, and a return of plague in 1921.
1.What was Dr Wu's mission in 1910?
A.To take personal risk.
B.To end an epidemic.
C.To provide medical education.
D.To investigate the number of victims.
2.Which of Dr Wu's acts stopped the disease from spreading nationwide?
A.Setting up special quarantine units around the country.
B.Treating infected persons with his medical instruments.
C.Checking households himself for possible cases.
D.Convincing authorities to close the railways.
3.What can we infer from the last two paragraphs?
A.The disease worsened after Mach 1, 1911.
B.60,000 would have died without Dr Wu's efforts.
C.A global health crisis followed the 1910-1911 outbreak.
D.The plague broke out again about 10 years later.
