China’s Tianhe-1 has a computing speed of 2,507 trillion（万亿）calculations a second, making it the fastest computer in the world. It is also 40 percent faster than the world’s second fastest supercomputer, Cray XT5 Jaguar, in the US, kept at a national laboratory in Tennessee, according to the New York Times. Jack Dongarra, a University of Tennessee computer scientist, told NYT that the Chinese supercomputer is faster than the existing Number One machine.
Building the fastest supercomputer has become a source of national pride, as these machines are valued for their ability to solve problems in areas like defense, energy and science. These problems are related to national interests. Supercomputing technology is also found in business. Oil and gas companies use supercomputers to find oil and gas.
Obviously, research centers with large supercomputers attract top scientific talents. This adds extra importance to the machines—they’re more than just huge computers.
China’s new supercomputer will be used to speed up greatly scientific calculations, such as hurricane and tsunami modeling, cancer research, car design and even studying stars.
In 2008, two US scientists put together a step-by-step guide on how to build a supercomputer using PlayStation 3 video-game consoles（控制台）. Modern supercomputers are built by combining thousands of small computer servers（服务器）and using software to turn them into one large computer. Really, any organization with enough material and technology can create a fast machine.
The Chinese system follows that model by linking thousands upon thousands of computer servers. But the secret behind the system—and the technological achievement—is China’s own networking technology. “That technology was built by them,” Dongarra said. “They are taking supercomputing very seriously and using a lot of time and money.”
“China is still a developing country,” said Sha Chaoqun, manager at Dawning Company which is the leading supercomputer maker in China. “Maybe one day, China’s total computing power can be greater than that of the US, but there is still a long way to go before we get there.”

核心考点

试题【China’s Tianhe-1 has a computing speed of 2,507 trillion（万亿）calculations a secon】；主要考察你对数词等知识点的理解。[详细]

举一反三

In Britain all children have to go to school between the ages of 5 and 16. In the US children must go to school from the age of 6 to between the ages of 14 and 16, depending on the state they live in.
Subject
In England and Wales the subjects taught in schools are laid down by the National Curriculum, which was introduced in 1988 and sets out in detail the subjects that children should study and the levels of achievement they should reach by the ages of 7, 11, 14 and 16, when they are tested. The National Curriculum does not apply to Scotland, where each school decides what subjects it will teach.
In the US the subjects taught are decided by national and local governments. Whereas British schools usually have prayers and religious instruction, American schools are not allowed to include prayers or to teach particular religious beliefs.
Examinations
At 16 students in England and Wales take General certificate of Secondary Education (GCSE) examinations. These examinations are taken by students of all levels of ability in all subjects and may involve a final examination, an assessment, or both of these things. At 18 some students take A-level examinations, usually in no more than three subjects. It is necessary to have A levels in order to go to a university .
In Scotland students take the Scottish Certificate of Education (SCE) examinations. A year later, they can take examinations called HIGHS, after which they can either go straight to a university or spend a further year at school and take the Certificate of Sixth Year Studies. In Scotland the university system is different from that in England and Wales. Courses usually last four years rather than three and students have to study a larger number of subjects as part of their degree.
In the US school examinations are not as important as they are in Britain. Students in High Schools do have exams at the end of their last two years, but these final exams are considered along with the work that the students have done during the school years.
Social Events and Ceremonies
In American high schools there is a formal ceremony for graduation . Students wear a special cap and gown and receive a diploma from the head of the school. Students often buy a class ring to ear, and a yearbook, containing pictures of their friends and teachers. There are also special social events at American schools. Sports events are popular, and cheer leaders lead the school in supporting the school team and singing the school song. At the end of their junior year, at age 17 or 18, students held in the evening. The girls wear long evening dresses and the boys wear TUXEDOS.
In Britain, there are no formal dances or social occasions associated with school life. Some schools have Speech Day at the end of the school year when prizes are given to the best students and speeches are made by the head teacher and sometimes an invited guest.

请认真阅读下列短文，并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。
注意：每个空格只填1个单词。
There are many destructive (破坏性的) forces when it comes to nature, which have destroyed whole cities and killed many people. They’re really terrible, but they occur somewhat often, and this is why you see so many charities these days which focus their efforts on helping people who have been affected by natural disasters.
While the world is a very beautiful place to live in, there will always be parts of the world where natural disasters happen more often than in other places, where properties and lives are destroyed. Only the people who live in the country where tsunamis and earthquakes as well as other disasters occur experience these, and we can only imagine the suffering that they go through.
For some people out there, the world is cruel, but they have no choice but to stay where they are. A lot of the time people simply cannot afford to move away, as they might not be able to get a job when they leave.
In 2004, there was a tsunami in the Indian Ocean. A tsunami is a large wave that towers hundreds of feet into the air, and covers whole areas when it comes crashing down on to dry land. This particular tsunami was caused by an earthquake that happened in the middle of the sea, shooting the water away from the ground and towards dry land. This tsunami actually reached thirty meters in height, and was one of the worst tidal waves the world has ever seen. Over 200,000 people were hurt in the disaster.
In 2005, we also saw a hurricane happened in the United States. This hurricane was known as hurricane Katrina, and is perhaps the worst in the history of the world. It happened in 2005 and destroyed millions of properties in the area. It also took the lives of nearly 2,000 American people. It was known that for ten days, the wind swept through the area, meaning the most powerful country in the world became helpless in their attempts to save the people who were affected by the hurricane.
Finally, in 2008 we saw yet another natural disaster. This time it was a cyclone (旋风), which is similar to a hurricane but happens in a circular motion (圆周运动). This cyclone Nargis had been one of the strongest to have ever occurred, reaching a death toll of nearly 150,000 people.
All of these were terrible disasters that were unavoidable.

In France, when a woman enters a café or restaurant, she is freely discussed, not only about her appearance but about her past and future as well. She invites looks in the street whether she is beautiful or plain. There is no better way for a woman to get back her self-confidence than a walk in the streets of Paris or Marseilles, and woman really like that.

The Swiss eat as a pastime. Ladies walk into a teashop, eat a couple of ice creams and a large piece of chocolate cake, and then leave, complaining about their weight.]
For the Americans, the greatest fondness is said to be the push of buttons. You push a button in the lift, you push a button for cigarette, chewing gums, stamps, even for a life insurance. You can even push a button to get married and another button to get divorced.
In England, waiting in a line is national passion. The English will form a line whether they have the opportunity or not. Long queues can be seen, for example, at stations when the train is practically empty and everybody can have a seat.

It"s good to make mistake, and here is why.
  小题1:   It’s always good to try new things because when you are trying new things you are growing. If you never try anything new, how can you improve? How can you expand? How can you innovate? The simple answer is "You can"t". Look around you. With very few exceptions, either everything you see in your physical world or every single detail of every single thing is the result of someone trying something new.
Another good thing about mistakes is this.  小题2:   Consider this: Edison failed 10000 times before he perfected the light bulb. When asked how it felt to fail that many times, he remarked that he hadn"t failed 10000 times, but rather had learned 10000 things that didn"t work.
Finally, when you make a mistake you are much closer to success. Why? Because when all is said and done, you will have tried some limited number of things before you succeed.   小题3:
But this all doesn"t mean that you should go ahead with disregard for the consequences of a mistake. Quite the contrary, you have to be willing to set some reasonable limits if it doesn"t work out the way you want it to.   小题4:
We all have limited resources in the form of time and money, so don’t blow them all on one approach to a problem. Realize that it probably won"t be perfect the first time and allocate these resources appropriately so you can learn, modify, and try it again. Only by embracing and using your mistakes in this way can you make significant advances in your business and your career.
There is an old truth that goes, "  小题5:   ”
So go forth and make mistakes. And learn. And grow. And prosper.

A．First of all, mistakes are a clear sign that you are trying new things.

B．Only those who do nothing make no mistakes.

C．If you"re not making mistakes, you"re not trying hard enough.

D．When you are making mistakes, you are learning.

E. You should take mistakes as stepping stone to future success.
F. You should guarantee you will be in a position to succeed again.
G. Every time you made a mistake you remove one of those things and are one step closer.
