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.

Radio announcers give the correct time during the day. People there think that it is important to know the time. Most Americans have watches. They want to do certain things at certain times. They do not want to be late. Not all people all over the world value time. Suppose you visit a certain country in South America. You would find that people living there do not like to rush. If you had an appointment with someone, he would probably be late. He would not care for arriving on time. In some countries in South America, even the radio programs may not begin right on time, nor do the radio announcers think it important to announce the right time. Many people regard a clock as a machine. It seems to them that a person who does everything on time is controlled by a machine. They do not want a clock or any machine to have that much power over their lives. Question: If you had an appointment with someone in some place in South America,he might not arrive on time,and this is because _ . Options: A: he didn't have a watch with him B: he didn't think it important to arrive on time C: he forgot to have a look at a watch or a clock D: he didn't like an appointment with someone

He had never been to camp before. So, Stanley Yelnats seems set to serve an easy sentence,which is only fair because he is as innocent as you or me. But Stanley is not going where he thinks he is. Camp Green Lake is like no other camp anywhere. It is a place that has no lake and nothing green. Nor is it a camp,at least not the kind of camp kids look forward to in the summertime. It is only a desert wasteland,dotted with countless holes dug by the boys who live at the camp. At Camp Green Lake,the warden makes the boys" build character" by spending all day, every day, digging holes:five feet wide and five feet deep. It doesn't take long for Stanley to realize there's more than character improvement going on at Camp Green Lake. The boys are digging holes because the warden is searching for something,and before long Stanley begins his own search--for the truth. Fate is to find a solution to it all--the family curse,the mystery of the holes. The great wheel of justice has ground slowly for generations,but now it is about to reveal its verdict . Question: Stanley Yelnats went to Camp Green Lake to _ . Options: A: enjoy the summertime B: show his innocence C: Serve his sentence D: make a choice
