Article: Mark Ramirez, a senior executive at AOL, could work in the comfortable leather chair, if he wanted. No, thanks. He prefers to stand most of the day at a desk raised above stomach level. "I've got my knees bent. I feel totally alive," he said. "It feels more natural to stand." In the past few years, standing has become the new sitting for 10 percent of AOL employees at the firm's Virginia branch. Part of a standing popularity is among accountants, programmers, telemarketers and other office workers across the nation. GeekDesk, a California firm that sells desks raised by electric motors, says sales will triple this year. Standers give various reasons for taking to their feet: It makes them feel more focused, prevents drowsiness , and makes them feel like a general even if they just push paper. (Former Defense Secretary Donald Rumsfels works standing up. So does novelist Philip Roth.) But unknown to them, a debate is spreading among ergonomics experts and public-health researchers about whether all office workers should be encouraged to stand--to save lives. Doctors point to surprising new research showing higher rates of diabetes, obesity, heart disease and even mortality among people who sit for long stretches. A study earlier this year in theAmerican Journal of Epidemiologyshowed that among 123,000 adults followed over 14 years, those who sat more than six hours a day were at least 18 percent more likely to die during the time period studied than those who sat less than three hours a day. "Every rock we turn over when it comes to sitting is astonishing," said Marc Hamilton, a leading researcher on inactivity physiology at the Pennington Biomedical Research Center in Louisiana. "Sitting is harmful. It's dangerous. We are on the cusp of a major revolution." He calls sitting "the new smoking". Not so fast, other experts say. Standing too much at work will cause more long-term back injuries. Incidences of varicose veins among women will increase. The heart will have to pump more. Hedge, the Cornell... Question: Which of the following is the best title of the passage? Yes or no, is the answer "More office workers take standing against sitting"?

No

Article: A South African farmer is receiving phone calls from his sheep after equipping them with cell phones to keep tabs on the flock amid recent livestock thefts, according to local press Wednesday. When the sheep call, it is always bad news for farmer Erard Louw of the Cape Town suburbs, as the phones around their necks are only set to switch on when the sheep start running, a sign that thieves have cut through the fences. "As they run it gives me a phone call and says 'Sheep One' or 'Sheep Two' and so on, so at least I know where to start looking because the farm is 750 hectares (1,850 acres)," Louw told the Cape Times daily. Louw attached the phone-like security device to the collars of four sheep in separate flocks after thieves sneaked in and stole 27 sheep and 13 lambs a couple of weeks ago, driving Louw to _ for ways to protect his animals. He said there was no use calling nearby police, as they were stationed too far away and in his experience they either lacked an available car or the vehicle was out of fuel or missing tyres -- also the work of thieves. According to Louw, the cell phones have already proved their worth, with one sheep-snatcher caught thanks to the device. Still, with theft attempts currently at their peak, given long winter nights and early nightfall, a few sheep-robbers managed to get away in spite of the device. "The phone did start ringing that night and I went out," he said, but added that he was too late. Question: Why did Erard Louw attach the phone-like device to the sheep he raises? Yes or no, is the answer "Because he wanted to protect them against thieves."?

No

Article: It is not only experts in China who are arguing over whether women should work after marriage or not. Worldwide this question is being discussed as an interestingly large number of married women enter the workplace. Take the United States for example. Since 1960, the percentage of married women in the work force has jumped from 31.9 per cent to 59.4 per cent. American women first moved into the paid labour force during the World War II, when men left their jobs to fight. In the last fifty years, more and more women have worked outside the home. And over these years of developing, Americans have changed their social values as a result. In 1975, women aged 35 and above made up half of all working women. And by 1980, 60 per cent were women at the age of 45 and above. Now in Japan, women's work group is M-shaped with middle-aged women and those aged 20-25 at the two peaks. According to statistics , 37.7 per cent of Japanese women at childbearing age(25-29) still engaged themselves in work in 1980. and the number reached 50 per cent the next year. Being a housewife has always been regarded as a "graceful occupation" in Japan. Some young Japanese women believe it is good to be a " professional housewife". However, old attitudes have been changing everywhere, and sometimes just out of economic necessary. In recent years, a great number of city housewives have poured out of homes to take part time jobs. Even the UN has given its support.. The 34thCongress of the United Nations in 1979 put forward the decision for formal agreement on the getting rid of discrimination against women. So far, most UN members have agreed on it, but some still haven't, including the United States. Question: From the first passage, we can learn that _ . Yes or no, is the answer "more and more people begin to care about women's life"?

No
