题目内容
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.”

【解析】
试题分析:文章讲述了中国超级计算机的研发成就及今后的发展趋势。
1.从文章making it the fastest computer in the world. 可知此处填makes
2.从文章It is also 40 percent faster than the world’s second fastest supercomputer, 可知,此处填second
3.从文章Jack Dongarra, a University of Tennessee computer scientist, told NYT that the Chinese supercomputer is faster than the existing Number One machine.
可知,此处填From,表明来自他的观点。
4.从文章Building the fastest supercomputer has become a source of national pride,可知填pride,把建立最快速的超级计算机作为一种骄傲。
5.从文章their ability to solve problems in areas like defense, energy and science.可知填able,be able to do sth表示能够做某事
6.从文章Supercomputing technology is also found in business. 可知此处填business
7.从文章Obviously, research centers with large supercomputers attract top scientific talents.可知此处填attracted
8.从文章They are taking supercomputing very seriously and using a lot of time and money.可知此处填seriously
9.从最后一段Mr. Sha 的话中可知对于计算能力的发展他的观点是保守的,故填attitude
10.从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.可知,尽管将来的某一天我们总体的运算能力比美国强但是仍然有很长的路要走,故填Despite
