Article: BEIJING - By the end of 2011 China-made supercomputers will say goodbye to foreign microchips and start using their own "Chinese core ", 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 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 _ 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. Question: What's the best title for this passage? Options: A: The Arrival of Chinese Supercomputers B: Homemade CPUs with a Long Way to Go C: The Supercomputers of Three Organizations in China D: Homemade CPUs on the Way for Local Supercomputers

Read the article and select the best answer. Article: John H. Johnson was born in a black family in Arkansas City in 1918. His father died in an accident when John was six . He was reaching high school age , but his hometown offered no high school for blacks . Fortunately he had a strong -- willed , caring mother . John remembers that his mother told him many times , "Son , you can be anything you really want to be if you just believe ." She told him not to be dependent on others , including his mother . "You have to earn success," said she . "All the people who work hard don't succeed , but the only people who do succeed are those who work hard ." These words came from a woman with less than a third --grade education .She worked hard as a cook for two years to save enough money to take her son -- then 15--to Chicago . Chicago in 1933 was not the promised land that black southerners were looking for . John's mother and stepfather could not find work . But here John could go to school , and here he learned the power of words -- as an editor of the newspaper at Du Sable High School . His wish was to publish a magazine for the blacks . While others discouraged him , John's mother offered him more words to live by : " _ " She also let him pawn her furniture to get the $500 he needed to start the Negro magazine . It is natural the difficulties and failures followed John closely until he became very successful . He always keeps his mother's words in mind: "Son , failure is not in your vocabulary ." Now John H. Johnson is one of the 400 richest people in America . Question: What's the best title of the passage ? Options: A: How John H. Johnson became somebody B: The mental support from a great mother C: The importance of a good education D: The key to success for blacks

Ques:Read the article and select the best answer. Article: Darek Fidyka, a 38-year-old Bulgarian, had been paralyzed from the chest down for four years after a knife attack. Scientists from Britain and Poland took cells from his nose, transplanted them into his back and re-grew his spinal cord . Now he can walk and even drive a car. The doctors were delighted but said it was the first step in a long journey. The breakthrough came after 40 years of research by Professor Geoff Raisman, who found that cells had the possibility to repair damage to nasal nerves, the only part of the nervous system that constantly re-grows. "The idea was to take something from an area where the nervous system can repair itself and put it into an area that doesn't repair itself," Professor Raisman said. Polish doctors injected the nasal cells into Mr Fidyka's spinal cord above the injury and used some nerves from his ankle to form a bridge across the damaged tissue. The nasal cells appear to have caused the spinal nerves to repair themselves. Professor Raisman achieved this with rats in the late 1990's, but this is his greatest success. "I think the moment of discovery for me was Christmas in 1997 when I first saw a rat, which couldn't control its hand, put its hand out to me. That was an exciting moment, because I realized then that my belief that the nervous system could be repaired was true." Doctors chose the easiest case for their first attempt--it might not work for others. But there is a real sense of hope that an idea once thought impossible has been realized. David Nicholls, who helped provide money for the breakthrough, said information about the breakthrough would be made available to researchers across the globe. "What you've got to understand is that for three million paralyzed people in the world today, the world looks a totally brighter place than it did yesterday," he said. Question: Why did Professor Geoff Raisman choose cells from the nose? Options: A: The nervous system in the nose can repair itself. B: Cells from the nose can be easily transplanted. C: The nervous system in the nose has more cells. D: Cells in the nose are able to re-produce rapidly.
