[Q]: Article: Born with easy-broken bone disease, Zhang Yonghong is only half a meter tall and must use a wheelchair. His thin arms and legs can hardly support any weight, and he is unable to take care of himself. However, his hands are able to produce fine paper-cuts, which will free his daughter from the same disease. To support himself, he learned how to make paper-cut art from his mother. He sold his artwork and taught his techniques in Xi'an for eight years before discovering his young daughter _ the disease from him, leading Zhang to move his family to Beijing for his daughter's better treatment five years ago. The daughter's treatment costs about 30,000 yuan a year. The family's savings was used up in two years, and Zhang was forced to start to sell his work in underground passages with his healthy wife, who soon left him because of the hard life. With a little help from government, he was lucky to meet some kindhearted people in Beijing. A Hong Kong businessman gave 60,000 yuan to him last year to treat the girl and start a small shop on Qiangulouyuan, which is known as a famous hutong that attracts lots of tourists over holidays. Zhang Rui, a university graduate, spends most of her time helping Zhang sell the paper-cuts, translating the stories of the paper-cuts into English and selling the works on the roadside of Nanluoguxiang. However, the artist still lives beyond his income and struggles to continue his small business. "Selling paper-cuts is his only source of income. Without this, he can't support the family and treat his daughter," says Zhang Rui, who hopes more people will help Zhang.
Answer: His easy-broken bone disease affected him.
[A]: Why did Zhang grow only half a meter tall?

[Q]: Article: A window is more than just an opening that you can see through. It can affect the way a building looks,how much energy a building USES and even how you feel. Scientists are now working on ncw technologies to create"smart windows". Unlike normal windows,high-tech smart windows can change from clear to dark and back again with the touch of a button --or even automatically as the outside light changes. Smart windows have the power to make the world a cleaner and more comfortable place. Instead of turning on air conditioners ,people could simply _ the windows in a building's empty rooms. With the rooms less bright,they would stay cool,and people would save energy and money at the same time. That's why smart windows are so exciting. Says Claes Granqvist. He's a professor of physics at Uppsala University in Sweden. If you think that you don't care much about windows,you should think again,Granqvist says. Most people who live in developed countries spend about 90% of their time inside buildings and cars. You might spend even more time than that indoors during the winter if you live in a cold climate. Imagine then what it would be like if there were no windows. You'd have no idea what's going on outside. So,the light of the nature is important for improving the way people feel when they stay indoors. The development of smart windows could mean that a lot of air-conditioning systems may no longer be needed. "In the future," Granqvist says "our buildings may look different."
Answer: They can change automatically or by pressing a button.
[A]: About the smart windows.which of the following is NOT true?

[Q]: Article: Is it true that cats have nine lives? One 4-year-old American cat named Sugar definitely seems to have more than one. Sugar fell from the 19th floor of her owner's home in Boston last month and was only hurt a little on her chest. "This story isn't much of a surprise," said Jake Socha, a scientist at Virginia Tech University, US, in an interview with the BBC. "There have been lots of records of these cats surviving." Back in 1987, scientists studied 132 cats. All of them had been brought to a vet's clinic in New York after falling from tall buildings. Around 90 percent of these cats were alive after their fall and only 37 percent had been seriously injured. "Being able to survive falls is a _ thing for animals that live in trees, and cats are one of them," said Socha. Cats have developed special body structures to survive accidental falls. Their legs are muscular. This can protect their bones from breaking, Professor Andrew Biewener from Harvard University told the BBC. Cats can also spread out their legs like a parachute to reduce their falling speed, he said. The strange part, according to scientists, is that cats have a better chance of survival if they fall from higher than seven stories. This is because cats have a good sense of which way is down. They can twist their bodies as they fall to make sure they land on their feet. A higher fall means more time for the cat to change its body position. However, you should not throw your cat out of the window to see how this works. Most pet cats are overweight nowadays. They are not fit enough to change their position in midair, warned Steve Dale, an American cat behavior scientist. "This cat (Sugar) was lucky," Dale said. In fact, most cats would suffer serious lung damage, a broken leg or a broken jaw or teeth damage, he said.
Answer: A cat that falls from the fourth story of a building is more likely to die than one that falls from the 10th story.
[A]:
