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.”

The world’s biggest Internet search engine, Google, has proven once again to be king of the Web. Users can download “Google Wi-Fi” software and then enjoy free Wi-Fi service available in some US cities since last Tuesday.

Wi-Fi is short for “Wireless Fidelity”(无线上网). It allows laptop computers and personal digital assistants to connect to the Internet at high speed by radio sigal.

A person with a Wi-Fi enabled computer can connect to the Internet when near one of the network’s access points. The place covered by one or several access points is called a hotspot. Google had already set up two “hotspots” in the US city of San Francisco which provide a free Wi-Fe service.

The Wi- Fi technology even allows users to enjoy a free Internet phone service. Some scientists argue that Wi-Fi may replace mobile phone networks.

Wi-Fi is stioo limited to a few cities, where there are “ hotspots”. But its capability(容量) of sending information has already done better than that of the mobile phone network, even that of 3G (Third Generation telecommunication technology). Some scientists have started to call Wi-Fi 4G.

In addition to a high speed Internet connection, Fi-Fi has other advantages compared to mobile phones. We-Fi is global. The same Wi-Fi system works in different countries around the world. Different from using cell phones, you don’t need to change computers to use Internet phones when you go to other places and most importantly, many Internet phones cost you nothing at all.

1. Wi-Fi is not available in cities without_____.

A. a computer   B. a radio   C. a hotspot   D. a cell phone

2. Which of the following is NOT the advantage of Wi-Fi?

A.  The high speed Internet connection.   B. Many free Internet phones.

Google, one of the world’s outstanding tech companies, was attacked. It wasn’t its search engine that was attacked or its advertising platform or even its social network, Google+. Instead, it was a building.

Two web security experts hacked (侵入) into its Wharf 7 office in Sydney, Australia, through Google’s building management system (BMS). One of them, Billy Rios, says, “My colleague and I have a lot of experience in web security, but it is not something that people couldn’t learn. Once you understand how the system works, it is very simple.”

They found the system on Shodan, a search engine that lists devices connected to the Internet, and then ran it through their own software to identify who owned the building. In the case of the Google hacking, the researchers had no immoral purpose and just informed Google about what they found.

According to Mr. Rios, Who runs security company Whitescope, there are 50,000 buildings currently connected to the Internet, including research institutes, churches and hospitals, and 2,000 of those are online with no password protection. Martyn Thomas, a professor of IT at Gresham College in the UK, says, “It is beyond doubt that attempts to attack building management systems arc happening all the time.”

Making a building smart generally means connecting the systems that control heating, Hating and security to the Internet and the wider corporate network. There was a strong reason for doing this, said Andrew Kelly, principal security consultant at defence company Qinetiq.

“Energy savings are the biggest factor in connecting building management systems to the corporate network,” he says. “It gives those who run the building better control and offers between 20% to 50% in energy savings,” he adds.

But it also makes them less secure. And if any of these feels like a Hollywood film, think again.

1.How did Billy Rios and his colleague hack Google’s building?

A. They invented a search engine and connected it to Google’s building.

B. They connected their own software to the building to run Google.

C. They worked for Google and mastered how the building worked.

D. They used Google’s BMS to find out the owner of the building.

2.In the case of the Google hacking, the researchers had the intention of 　　　　 .

A. telling Google about the Wharf 7 office’s hidden danger

B. entering Google’s building to save more energy

C. explaining the reasons for energy savings

D. analyzing some immoral problems

3.What’s the main idea of Paragraph 4?

A. There are many researchers contributing a lot to web security.

B. The attack on building management systems happens all over the world.

C. The building management systems of some buildings are in danger.

D. There are too many buildings connected to the Internet to be managed well.

4.What is the author’s attitude towards the way of the energy savings of some buildings?

A. Favorable.　　 B. Ambiguous.

C. Indifferent　　 D. Negative.

On March 23, 2010, Google Inc took a major step in withdrawing(收回) its search-engine services from Beijing to Hong Kong. Google acknowledged that it failed to make progress in talks with the Chinese government for permission to let Google stop censoring(审查) its search results.

Since posting the announcement on its website, Google’s stock(股票) price has fallen from $595 to about $567, while Baidu, the leading search engine in China, has seen its stock price rise by 50%. A potential foreign beneficiary(受益者) is Bing, Microsoft’s new search engine. And while Bing may not exactly have got the keys to a very rich kingdom, its managing group understand their good fortune and have not been shy about sticking the knife into Google. Craig Mundie, a chief officer of Bing, told China Daily that “we feel good enough now,” adding, “but it’s a 20-year journey, and not just three years. And Microsoft is here to stay.”

Several other Chinese Internet companies are no doubt moving swiftly to take advantage of this situation. Both Sohu. com—a Yahoo-like website in China— and a hugely successful instant-messaging company called Tencent(腾讯) are already trying to hire Google China staff. Analysts believe that of the two, Tencent is in the better position. Nearly 70% of China’s 400 million Internet users use instant-messaging, and of those, 80% use Tencent’s system, known as QQ. That’s the major reason why Tencent’s potential market is bigger than Baidu’s, and an insider at the company acknowledges that the search business is full of opportunities.

All the competitors of Google do what the Chinese government requires: censor their search results. If Microsoft and the others intend to be in China “to stay,” as Craig Mundie put it, there is no chance that the censoring principle will change for them.

As to the Google’s exit, one of its investors made the comment recently, “There’re still a lot of us who believe that they’ve made the wise choice. But Google is apparently out and I guess we just get to accept.” However, some Chinese netizens regretted the loss of its professional services on google. cn, such as maps, videos, music and translations.

73.Google.cn stops its business in China because _____.

A. too many companies enter the market         B. its stock price has fallen sharply

C. Chinese companies hire its workers           D. it refuses to censor the search results

74.How many Chinese beneficiaries are mentioned in the passage?

A. Two.               B. Three             C. Four.               D. Five.

75.When Google withdraws, _______.

A. Chinese netizens won’t have any professional service

B. only Chinese companies will provide search service

C. China’s attitude towards censoring won’t be changed

D. the Google managing group will regret its decision

76.A suggested title for this news would be ______.

A. When Google Withdraws From China        B. Who Wins in China’s Search Business

C. Who Will Profit When Google Exits         D. Why Google Loses to Other Competitors
