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?

My son and I were trying to sell the house we had repaired, but in the barn（谷仓）there were bats and they would not leave. The barn was their home. They told us so in their own way they hung for the season. “Don’t worry about it, Dad.” Patrick said. “They keep down the mosquitoes（蚊子）.”
Unfortunately they also kept the buyers away. When we had asked a person to sell the house for us he had refused to show it because of the bats. “Bats are popular,” Patrick comforted me. “They are ecological.” “Isn’t there a machine you can buy that produces high-frequency sounds to keep bats away?” “ I don’t know,” said Patrick. “But I like bats, and whoever buys this house will probably like them too.’ “Probably?” I hated that word. “How many bats are there, anyway?” “I counted about 90 last night,” said Patrick. “They were dropping out from under the edge of the roof.” “You mean there are more------outside?” “They’re everywhere, Dad. But look at it this way. When the cold weather comes, they’ll be off to Mexico. Maybe in the spring we can keep them out. Don’t worry about it,” he said for the
the hundredth time. “It’s not a problem.”
The bat expert I called was even more active than Patrick. “I think you’ve got a large number there,” he said in wonder. “I’ve been trying to attract bats to our house for 25 years. A single bat ears up his weight in mosquitoes and black flies three times every night. You’ve a very lucky man.” I offered to share my luck with him. He could take them away. “Bats have a remarkable homing instinct（本能）,” he said. “They’d fly straight back even if I transported them 100 miles. Once they have settled, you can’t stop them from coming back.” I was silent.
Finally we managed to rent the house to a young family, who were also interested in buying it. “What about the bats?” I said to Patrick. “Oh, they love the bats,” he said. “No mosquitoes. No black flies. It’s one of the things that attracted them.” “Do you think they will really buy the house?” “Probably? Well, if they do, I suppose I’ll have to admit that I was wrong.” “You mean you’re going to eat your words?”

Have you ever suddenly felt that someone you knew was in trouble —and was he? Have you ever dreamed something that came true later? Maybe you have ESP（特异功能）. ESP stands for Extrasensory Perception. It may be called a sixth sense. It seems to let people know about events before they happen, or events that are happening some distance away.
Here’s an example. A woman was ironing clothes. Suddenly she screamed, “My father is dead! I saw him sitting in the chair!” Just then, a telegram came. The woman’s father died of a heart attack. He died sitting in a chair.
There are thousands of stories like this one on record. Scientists are studying them to find out what’s behind these strange mental messages. Here’s another example —one of hundreds of dreams that have come true.
A man dreamed he was walking along a road when a horse and carriage came by. The driver said, “There’s room for one more.” The man felt the driver seemed dead, so he ran away. The next day, when the man was getting on a crowded bus, the bus driver said. “There’s room for one more.”
Then the man saw that the driver’s face was the same face he had seen in the dream. He wouldn’t get on the bus. As the bus drove off, it crashed and burst into flames. Everyone was killed!
Some people say stories like these are coincidences. Others, including some scientists, say that ESP is real. From studies of ESP, we may someday learn more about the human mind.According to the passage, the author believes that the sixth sense is ______.
| A．possible | B．imaginative |
| C．not real | D．impossible |
By studying ESP, scientists may get to ______.
| A．learn how people tell lies |

In the last paragraph the underlined word “coincidences” probably means “______”.
| A．things that may not happen |
| B．things that happen by accident |
| C．things that must happen |
| D．things that happen in a dream |
This article is mainly about ______.
| A．the human dream | B．a crowded bus |
| C．the human mind | D．the sixth sense |
How many men do housework? Recently a European Commission tried to find out people’s ideas and reactions to the women’s movement. As part of their survey (调查), they asked many men and women the question, “Who does the housework?” The men answered very differently from the women!
The housework they asked people about were: preparing meals, washing dishes, cleaning the house and babysitting. 48% of British husbands said they did these things. 37% of Danish men helped in the house. But only 15% of Italian men said they did the housework, many of them said they never helped at all!
But there was an interesting point of view from the wives. According to British wives, only 38% of their husbands helped in the house. And Italian wives said that their husbands hardly ever helped. The Italian and British men did not tell the truth! The Commission found that Danish men were the most trustful husbands; their answers were the same as their wives’ answers.
Do the men you know help in the house? Do you think the survey gives a true picture in your experience? Write and tell us what you think.The survey was carried out in ______.

The elephant was lying heavily on its side, fast asleep. A few dogs started barking at it. The elephant woke up in a terrible anger: it chased the dogs into the village where they ran for safety. That didn't stop the elephant. It destroyed a dozen houses and injured several people. The villagers were scared and angry. Then someone suggested calling Parbati, the elephant princess.
Parbati Barua’s father was a hunter of tigers and an elephant tamer（驯兽者）. He taught Parbati to ride an elephant before she could even walk. He also taught her the dangerous art of the elephant round-up -- how to catch wild elephants.
Parbati hasn’t always lived in the jungle. After a happy childhood hunting with her father, she was sent to boarding school in the city. But Parbati never got used to being there and many years later she went back to her old life. “Life in the city is too dull. Catching elephants is an adventure and the excitement lasts for days after the chase,” she says.
But Parbati doesn’t catch elephants just for fun. “My work,” she says, “is to rescue man from the elephants, and to keep the elephants safe from man.” And this is exactly what Parbati has been doing for many years. Increasingly, the Indian elephant is angry: for many years, illegal hunters have attacked it and its home in the jungle has been reduced to small pieces of land. It is now fighting back. Whenever wild elephants enter a tea garden or a village, Parbati is called to guide the animals back to the jungle before they can kill.
The work of an elephant tamer also involves love and devotion. A good elephant tamer will spend hours a day singing love songs to a newly captured elephant. “Eventually they grow to love their tamers and never forget them. They are also more loyal than humans,” she said, as she climbed up one of her elephants and sat on the giant, happy animal. An elephant princess indeed!For Parbati, catching elephants is mainly to ______.
| A．get long lasting excitement |
| B．make the angry elephants tame |
| C．send them back to the jungle |
| D．keep both man and elephants safe |

| C．elephant tamers are in short supply |
| D．the man-elephant relationship is getting worse |
Rome had the Forum (论坛). London has Speaker’s Corner. Now always-on-the-go New Yorkers have Liz and Bill.
Liz and Bill, two college graduates in their early 20s, have spent a whole year trying to have thousands of people talk to them in subway stations and on busy street comers. And just talk. Using a 2-foot-tall sign that says, “ Talk to Me,” they attract conversationalists, who one evening included a mental patient, and men in business suits.
They don’t collect money. They don’t push religion (宗教). So what’s the point?
“To see what happens,” said Liz. “ We simply enjoy life with open talk.”
Shortly after the September 11, 2001 attacks, they decided to walk from New York City to Washington, a 270-mile trip. They found they loved talking to people along the way and wanted to continue talking with strangers after their return. “ It started as a crazy idea.” Liz said. “ We were so curious about all the 10 strangers walking by with their life stories. People will talk to us about anything: their job, their clothes, their childhood experiences, anything.” Denise wanted to talk about an exam she was about to take. She had stopped by for the second time in two days, to let the two listeners know how it went. Marcia had led her husband to a serious disease. “That was very heavy on my mind.” Marcia said. “ To be able to talk about it to total strangers was very good,” she explained.
To celebrate a year of talking, the two held a get-together in a city park for all the people they had met over the past year. A few hundred people appeared, as well as some television cameramen and reporters. They may plan more parties or try to attract more people to join their informal talks. Some publishers have expressed interest in a book, something the two say they’ll consider before making a decision.
