Article: If you are sitting down listening to what I'm going to say, stand up. Move your legs. Touch your toes, if you can. Do anything but sit. If you cut down on the time you spend sitting, you might live longer. New research shows that sitting less than three hours a day might extend your life by two years. Just the opposite, says Peter Katzmarzyk. He is a scientist at the University of Louisiana in the southern United States. He says that sitting is _ in our lives. "We sit while we're eating; we sit in the car; we sit while we watch TV. Many of us sit for many hours at work. " But, he adds, that does not make sitting good for us. The human body is designed to move. But modern lifestyles and office jobs rarely give us the chance to move around. Exercise is important. So is not sitting. "We can't throw away physical activity. It's extremely important. We have 60 years of research showing us that. Even if you exercise for 30 minutes a day, what goes on in the other 23-and-a-half hours a day is also very important." Mr. Katzmarzyk and his co-workers are part of a new generation of researchers studying how sitting all day affects length of life. This is a relatively new area of study--studies that have assessed the relationship between sitting and mortality or television viewing and mortality. Making uses of the few studies available to them, they found that cutting television time to less than two hours a day could add one-point four years to life. New desk designs are helping Change is already coming to some offices, especially in the design of desks. A "standing desk" lets people stand while they work. Another new design is called the "treadmill desk." A treadmill is an exercise machine that lets you walk in one place. That's one of the strategies that many companies are using now. Some companies may equip their employees with a "standing desk" or a "treadmill desk". Other companies may not buy one for everybody, but they'll have a bank of these desks where people can go for an hour a day and answer their emails or talk on the phone. Even some U.S. schools are beginning to experiment with such desks to keep children moving. Mr. Katzmarzyk says studying this problem has inspired his team to make a few changes in their own lives. "As a university professor, you know, it is a very sedentary occupation. We're chained to a desk in terms of writing papers and doing research. We really try to limit the amount of time we spend doing that." Suggestions for sitting less If you work in office job or have a sedentary job, Mr. Katzmarzyk and his team suggest a few simple changes: get up from your desk as often as you can take walks at lunch time walk to your colleagues' offices and talk directly instead of emailing them All these activities may help you live longer.
Question: What might be the best title for the passage?
Options: (A) Take exercise, keep fit. (B) Change more, achieve greater. (C) Talk directly, improve relationship. (D) Sit less, live longer.

Article: One day a student was taking a walk with his teacher. As they went along, they saw a pair of old shoes lying in the path. They were a poor farmer's, who was working in the nearby field. The student turned to the teacher, saying: "we will hide his shoes, and hide ourselves behind those trees, and wait to see what he will do." "My young friend," answered the teacher, "we should never make fun of the poor. Why not put a coin in each shoe, and then we will hide ourselves and watch?" The student did so and they both hid themselves behind the trees. The poor man soon finished his work, and came across the field to the path where he had left his coat and shoes. After putting on his coat, he put his foot into one of his shoes, and felt something hard. Then he bent down to feel what it was, and found the coin. Surprised, he looked at the coin, turned it around and looked at it again. He then looked around, but no person was seen. He put the money into his pocket, and continued to put on the other shoe. His surprise was doubled on finding the other coin. He couldn't control his feelings and fell to his knees, looked up to the sky and expressed his thanks. Then he spoke of his wife, sick and helpless, and his children without bread. He said the help would save them from dying. The student stood there deeply moved, and his eyes filled with tears. "Now," said the teacher, "are you not much happier than if you had hidden the shoes?"

Article: Oliver Radtke believes Chinglish mistranslations may be fun, but are not to be made fun of. "My message on Chinglish is: It should be conserved . It shouldn't be treated as a cheap joke for foreign tourists to laugh at but as a cultural treasure," said the 32-year-old multimedia designer, who frequently visited China for almost a decade before moving to Beijing in 2007. "I'm trying to challenge the idea that there is only one type of standard English -- the English that's spoken in America or in the British Isles -- which is shortsighted, because Chinglish is already being used by millions of people to communicate with one another." So, since 2005, he has collected more than 5,000 examples of "the wonderful results of an English dictionary meeting Chinese grammar" on his website www.chinglish.de and has published two books on the subject. "The two books are unique in that they talk about the academic value of Chinglish, the creative combination of English and Chinese, and why we should keep it," Radtke said. Patricia Schetelig, who works for the German Embassy in Beijing and regularly contributes to www.chinglish.de, said she appreciates Radtke's approach to Chinglish. "What's important to me is that he's not making fun of the way things are translated," said she. "There are other websites doing similar things, but they're making fun of Chinglish or saying it shouldn't be done this way." Part of his mission, Radtke said, is to conserve rapidly disappearing Chinglish examples. He was disappointed while watching the government replace Chinglish signs with standard English ones in the run-up to the Beijing Olympics. "That was a sad day for me and a sad day for Chinglish," Radtke said. But American David Tool, who has been closely involved in cleaning up Chinglish in Beijing since 2001, disagreed. "Chinglish takes away from the aesthetic , educational and cultural value we want these signs to provide," said Tool, "We get distracted when we're trying to explain something. It's not dealing with the issues with respect."
Question: Which of the following statements does Radtke agree with?
Options: (A) Chinglish will gradually disappear as years go by. (B) Chinglish is invented to amuse foreign tourists. (C) Chinglish will be treated as a cultural treasure. (D) Chinglish is actually a variety of English.
