Ques:Article: Today most Chinese teenagers are happy to be favored by two parents and four grandparents in their families. But have you ever thought about how to take care of four to twelve old people when you grow up and get married? This could be a problem for most Chinese youths as China is entering a new stage of an aging society. An aging society refers to one where 10 percent or more of its population is over 60. By the end of 2007, Chinese over 60 years old have made up 11.7 percent of the nation's total population. "China is getting old before becoming rich,"said Cai Chuang, a professor at the Chinese Academy of Social Sciences. The population increase that has powered Chinese growth for three decades will give way over the next ten years to a rapid aging of the society. This will lead to weaker economic growth, because of a lack of labor resources. As a result of the family planning policy, it is expected that the country's total working population will decrease after 2015. China is not the only country getting old. More that 60 countries have become aging societies and one in three people in the European Union is a senior citizen. However, experts said that China doesn't have a highly developed social security network to support the old. Social security is an insurance program protecting those in need, including the old, the disabled and others. Question: What does Cai Chuang mean by saying"China is getting old before becoming rich."? Yes or no, is the answer "An aging society will affect Chinese economy development."?

Ques:Article: If a diver surfaces too quickly, he may suffer the bends. Nitrogen dissolved in his blood is suddenly liberated by the reduction of pressure. The consequence, if the bubbles accumulate in a joint, is sharp pain and a bent body -- thus the name. If the bubbles form in his lungs or brain, the consequence can be death. Other air-breathing animals also suffer this decompression sickness if they surface too fast: whales, for example. And so, long ago, did ichthyosaurs . That these ancient sea-animals got the bends can be seen from their bones. If bubbles of nitrogen form inside the bone they can cut off its blood supply. This kills the cells in the bone, and consequently weakens it, sometimes to the point of collapse. Fossil bones that have caved in on themselves are thus a sign that the animal once had the bends. Bruce Rothschild of the University of Kansas knew all this when he began a suty of ichthyosaurs bones to find out how widespread the problem was in the past. What he particularly wanted to investigate was how ichthyosaurs adapted to the problem of decompession over the 150 milllion years. To this end, he and his colleagues traveled the world's natural-history museums, looking at hundreds of ichthyosaurs from the Trassic period and from the later Jurassic and Cretaceous periods. When he started, he assumed that signs of the bends would be rarer in younger fossils, reflecting their gradual evolution of measures to deal with decompression. Instead, he was astonished to discover the opposite. More than 15% of Jurassic and Cretaceous ichthyosaurs had suffered the bends before the died, but not a single Trassic specimen showed evidence of that sort of injury. If ichthyosaurs did evolve an anti-decompression means, they clearly did so quickly -- and, most strangly, they lost it afterwards. But that is not what Dr Rothchild thinks happened. He suspects it was evolution in other animals that caused the change. Whales that suffer the bends often do so because they have sufaced to escape a predator such... Question: Rothchild might have concluded that ichthyosaurs _ . Yes or no, is the answer "failed to evole an anti-decompression means"?

Ques:Article: A lot of kids have dreams they'll never achieve due to the limitations of their little bodies. They want to fly, or to become a dinosaur, or to learn how to act like Spiderman. Luka Tavcar, 12, has muscular dystrophy and is totally dependent on his wheelchair. Nevertheless, late last year, he had an inspired plan: to be photographed walking around and having fun. He approached Matej Peljhan, an amateur photographer and a psychologist at CIRIUS rehabilitation center near Ljubljana, Slovenia, where Luka is a patient. At first, Peljhan was perplexed. How could he photograph a boy who can not move or act in motion? "Luka wanted to see himself playing and having fun, but it seemed impossible," he says. Then Peljhan had a brainstorm: Luka could lie down on a piece of cloth and, with the help of an assistant, Peljhan would pose the boy as if he were jumping, climbing stairs, moving downhill on a skateboard, and playing basketball. Then Peljhan would shoot these images from above. The photos took about a month to produce; all were shot early this year. Peljhan, who lost his right arm and left eye as a child, says his own disabilities motivated him to make the photographs. "I understand people with limitations," he says. He named the series "The Little Prince" after the French story by Antoine de Saint-Exupery in which a boy teaches a man about trust, hope, and friendship. Luka loves the photos. Matej himself understands what it is like to live with limitations--he lost his right arm and left eye as a child."Luka wants to stay positive and his imagination helps him forget his physical limitation," says Peljhan. "He's fragile, but he can see the world differently." Question: What's the best title of the passage? Yes or no, is the answer "A Positive Disabled Boy--Luka"?

Ques:Article: Not long ago, people could only buy organic food in small shops. Today it is common in most major supermarkets. The reason for the increase is that more and more people are demanding food grown without chemicals. Since the 1990s, organic farm production has gone up 20 percent every year. This pattern is expected to continue around the globe. Australia leads the world in land used for organic agriculture. It has four times as much land devoted to organic farming as all of Asia. However, most of the land is not very fertile, and it only produces a modest amount of food. Argentina is a distant second, followed by Brazil, the United States and China. In Africa, only a very small amount of land is registered for organic farming. That does not mean Africa relies on chemicals. In fact, many farmers do not use chemicals because they cannot afford them. Yet there are no programs for these farmers to prove they do not use chemicals. Without these programs their food can never be approved organic. India has had the most dramatic recent increase in organic farming. Like many other countries, India sees continual growth in organic food sales around the world. This, of course, leads to growth in profits. Sales of organic food were more than doubled from 2000 to 2005. Like India, many countries are trying to increase commercial organic farming to get a share of the sales. This has led to criticism. Some people believe that organic farming should not just be about making money. They think the goal is to help the environment. Others say organic farming will not continue if it is not profitable. They say that people should be able to make money while providing food that is healthy to mankind. Question: Why do people want to increase organic farming? Yes or no, is the answer "Organic food is good for the Earth and the human beings."?

No
