BEIJING - By the end of 2011 China-made supercomputers will say goodbye to foreign microchips（微芯片） and start using their own "Chinese core(核心)", according to one of the country's leading scientists, Hu Weiwu.
Hu told reporters on Saturday that the "Dawning 6000" supercomputer, developed by the Institute of Computing Technology of CAS and the Dawning Information Industry Company (DIIC), will adopt Loongson microchips for the first time as its core parts. It will have a computing speed of more than 1,000 trillion operations a second.
Making supercomputers with Chinese microchips is one of the nation's major science and technology projects. Three organizations - the Institute of Computing Technology of CAS, Jiangnan Institute of Computing Technology and the National University of Defense Technology (NUDT) - have their own supercomputer projects.
According to their schedules, all three institutions will need to meet the target of using domestically（国内的） developed microchips by the end of this year. Hu said the new supercomputer will use fewer than 10,000 Loongson microchips, and will also be more energy-efficient.
Tianhe-1A, developed by NUDT in Hunan's provincial capital Changsha, is the fastest supercomputer in the world. However, Tianhe-1A largely runs on 14,336 CPUs made by Intel, and 7,186 GPUs (processing units) from Nvidia, two US chip-makers.
Hu said there will be difficulties ahead as there is little affiliated equipment specially developed for these supercomputers. "We have enough supercomputers in China but still can't make full use of them," He said.
Hu added that although the China-made CPUs have improved since they were first produced in 2002, they have a long way to go to compete with US chip-makers such as Intel.What’s the best title for this passage?

When you get in your car, you reach for it. When you're at work, you take a break to have a moment alone with it. When you get into a lift, you play with it.
Cigarette? Cup of coffee? No, it's the third most addictive thing in modem life, the cell phone. And experts say it is becoming more difficult for many people to curb their longing to hug it more tightly than most of their personal relationships.
The costs are becoming more and more evident, and I don't mean just the monthly bill. Dr.Chris Knippers, a counselor at the Betty ford Center in Southern California, reports that the overuse of cell phones has become a social problem not much different from other harmful addictions: a barrier to one-on -one personal contact, and an escape from reality. Sounds extreme, but we' ve all witnessed the evidence: The person at a restaurant who talks on the phone through an entire meal, ignoring his kids around the table; the woman who talks on the phone in the car, ignoring her husband; the teen who texts messages all the way home from school, avoiding contact with kids all around him. Jim Williams, an industrial sociologist based in Massachusetts, notes that cell - phone addiction is part of a set of symptoms in a widening gulf of personal separation. He points to a study by Duke University researchers that found one-quarter of Americans say they have no one to discuss their most important personal business with. Despite the growing use of phones, e - mail and instant messaging, in other words, Williams says studies show that we don't have as many friends as our parents. “Just as more information has led to less wisdom, more acquaintances via the Internet and cell phones have produced fewer friends,” he says.
If the cell phone has truly had these effects, it's because it has become very widespread. Consider that in 1987, there were only l million cell phones in use. Today, something like 300 million Americans carry them. They far outnumber wired phones in the United States.From the first two paragraphs, we can know ．
| A．cell phones have become as addictive as cigarettes |
| B．cell phone addiction is good for building personal relationships |
| C．people are longing to have their own cell phones |
| D．cell phones are the same as cigarettes |
Cell phone addiction has caused the following effects EXCEPT .
| A．a barrier to personal contact | B．fewer friends |
| C．an escape from reality | D．a serious illness |
The underlined word "curb" in Paragraph 2 means “ ．”
| A．ignore | B．control | C．develop | D．rescue |
The example of a woman talking on the phone in the car supports the idea that .
| A．women Use cell phones more often than men |
| B．talking on the phone while driving is dangerous |
| C．cell phones do not necessarily bring people together |
| D．cell phones make one - on - one personal contact easy |
Which of the following is the best title for the passage?
| A．Cell phones Are the New Cigarettes |
| B．Cell phones Are Harmful to the Society |
| C．The New Report about the Cell phone |
| D．The Disadvantages of the Cell phone |
Not long ago the movie 2012 came into screen. The people were threatened by those scenes of destroying flood, severe earthquake, terrifying hurricane and constructions representing human civilization being destroyed and even swallowed by disaster. Luckily, they are just the director’s imagination, but the present situation is not heading a positive direction, either.
Take my own experience in Alaska as an example. Once I took a trip to the glacier. Along the way there stood signposts marking the snow lines of different years. They started from the foot of the mountain, but it was at the top when I finally saw melting glaciers(融化的冰川). My heart ached seeing the beautiful blue ice melting at every second.
Sad but true, they are the effects of global warming and the result of our human impact. Furthermore, each year the rising sea level will kill 56 million people, and that's about the population of the en tire Italy. According to studies, if the temperature keeps on rising like this, by the year 2050, some islands and coastal cities including New York, Shanghai, Tokyo and Sydney will be drowned in water.
Our fortune is in our own hands. It depends on us to shape our future, to reduce future human impact and find ways to form a peaceful relationship with our environment. Therefore, it's time for actions to be taken right now. Contribute a little to energy saving by using more efficient light bulbs and less hot water. Let recycle become our habit by thinking twice before throwing something away. Let us take public transportation as our first choice when going to a certain place. It might cost more time for now, but it' s to the benefit of a permanent future. Take care of every tree and grass around us by watering them or simply just avoid destroying them．
In a word, small drops of water make a big ocean. The earth does not belong to us. On the contrary, we belong to the earth. Please bear in mind that the earth is our home. It is our responsibility to build a brighter and better future of our planet and prevent what happened in the movie 2012 from becoming reality． Why does the author talk about the movie 2012 in the passage ?

Some Chinese new - rich like eating shark fin soup because they think it shows their class. However, for the Chinese NBA idol Yao Ming, doing so is unacceptable as the practice has led to the overfishing of sharks.
When Yao and his wife Ye Li got married in 2007, they publicly announced that they would not allow shark fin soup to be served at their wedding banquet.
Actually, Yao had been saying no to shark fins since 2006, when he was appointed as the Goodwill Ambassador for wild life protection.
Now, the 226 - cm big guy is resorting to his personal influence to encourage more to say no to eating the soup and to raise awareness of protecting animals. “Sharks are friends of human beings. They are not our food,” Yao said.
Other celebrity athletes like Olympic champions. Li Ning and Kong Linghui are following on the heels of Yao, throwing themselves into serving the public as Goodwill Ambassadors for wild animal rescue. Recent reports about Yao’s retirement have saddened tens of thousands of basketball fans both at home and abroad. Yet Yao's influence goes far beyond the basketball courts.
Yao has engaged himself in charity and public welfare services for quite a while. When the devastating 8.0 －magnitude earthquake hit Wenchuan in southwest China in 2008 , Yao donated 2 million yuan. “When I was a little boy, my parents and teachers told me to help others and to be a good man,” Yao recalled. “But I could nor donate then because I had not much pocket money. After I moved to Houston, I got involved in quite a number of community service activities and I felt a strong sense of achievement when I got people together,”Yao said.
Like Yao, newly crowned French Open champion Li Na has showed her willingness to donate. Li gave 480,000 yuan of her prize money from the open, plus 20,000 yuan from her own pocket, to a local nursing home in her hometown. Another Chinese sports icon, hurdler Liu Xiang, has also been actively involved in charity for years.The reason why some Chinese new-rich like eating shark fin soup is that they think ．
| A．it is very delicious | B．it is very cheap and healthy |

Yao Ming is against eating shark fin soup because ．
| A．too many sharks are killed | B．he dislikes eating sharp fin |
| C．it is too expensive | D．sharks are dangerous animals |
Which of the following statements is NOT TRUE?
| A．Li Na donated 500,000 yuan to a local nursing home in her hometown． |
| B．Yao Ming donated 2 million yuan after the earthquake of Wenchuan． |
| C．Yao Ming has encouraged more people to stop eating shark fin soup and protect animals． |
| D．Yao Ming was appointed as the Goodwill Ambassador for protecting wild life in 2007． |
What words can be used to describe Yao Ming according to the passage?
| A．Rich and generous． | B．Influential and warmhearted． |
| C．Energetic and optimistic． | D．Popular and confident． |
