Elderly adults who regularly drink green tea may stay more agile and independent than their peers over time, according to a Japanese study that covered thousands of people. Green tea contains antioxidant chemicals that may help stop the cell damage that can lead to disease. Researchers have been studying green tea's effect on everything from cholesterol to the risk of certain cancers, with mixed results so far. They found those who drank the most green tea were the least likely to develop "functional disability", or problems with daily activities or basic needs, such as dressing or bathing. Specifically, almost 13 percent of adults who drank less than a cup of green tea per day became functionally disabled, compared with just over 7 percent of people who drank at least five cups a day. The study did not prove that green tea alone kept people agile as they grew older. Green-tea lovers generally had healthier diets, including more fish, vegetables and fruit, as well as more education, lower smoking rates, fewer heart attacks and strokes, and greater mental sharpness. They also tended to be more socially active and have more friends and family to rely on. But even with those factors accounted for, green tea itself was tied to a lower disability risk, the researchers said. People who drank at least five cups a day were one-third less likely to develop disabilities than those who had less than a cup per day. Those people who averaged three or four cups a day had a 25 percent lower risk. Although it's not clear how green tea might offer a buffer against disability, Tomata's team did note that one recent study found green tea extracts seem to increase leg muscle strength in older women. While green tea and its extracts are considered safe in small amounts, they do contain caffeine and small amounts of vitamin K, which means it could affect drugs that prevent blood clotting . What can be learned from the passage? A) Antioxidant chemicals can lead to disease. B) Those who often drank green tea can't develop "functional disability". C) "Functional disability" is related to problems with daily activities or basic needs. D) People who drank at least five cups a day are not likely to become functionally disabled.

Nicole Delian, 17, suffers from a condition that makes her sleep up to 19 hours a day and as much as 64 days in a row. Nicole Delian is tired of sleeping. This 17-year-old teenager from North Fayette, Pa., has a rare condition called Kleine-Levin Syndrome -- or "Sleeping Beauty Syndrome" -- that makes her sleep 18 to 19 hours a day. And when she does wake up, she is often so tired out that she is in a sleepwalking state and doesn't remember doing basic things like eating, according to KDKA-TV. Nicole's sleepwalking state has been so severe that she once slept through the holidays, awaking one day in January when she finally opened Christmas gifts alongside her family, according to ChartiersValley.Patch.com. . "She's never really adjusted to it," her mother, Vicki Delien told the website. "She's 17 now and it really upsets her. She's missed out on a lot." Delien told talk show host Jeff Probst that the teen has at times slept 32 to 64 days in a row, waking only in sleepwalking mode to eat. Kleine-Levin Syndrome is incredibly rare, only affecting about l,000 people worldwide, and very hard to diagnose. In Nicole's' case, it took 25 months for doctors to diagnose her, according to ChartiersValley.Patch.com, and everything from a virus, to epilepsy to West Nile was mentioned, including, unfortunately, the possibility she was faking it for attention.. When a typical episode of Sleeping Beauty Syndrome begins, the patient becomes progressively drowsy and sleeps for most of the day and night, waking only to eat or go to the bathroom, according to the Klein-Levin Syndrome Foundation website. "When awake, the patient's whole behavior is changed, often appearing "stupid" or childlike. When awake he experiences confusion, complete lack of energy, and lack of emotions." Patients also report that everything seems out of focus, and that they are hypersensitive to noise and light. Some patients also have intense food cravings . The Delians did not say whether Nicole has experienced these symptoms. There is no... Frorn the passage we can infer that_. A) the disease will change the patients' behavior for good B) the case of Nicole has been covered several times by different media C) the.patients of this kind are more and more sleepy when the syndrome begins D) the patients of this kind become too sensitive to being exposed to any noise and light

*Question*
Surprisingly, no one knows how many children receive education in English hospitals, still less the content or quality of that education. Proper records are just not kept. We know that more than 850,000 children go through hospital each year, and that every child of school age has a legal right to continue to receive education while in hospital. We also know there is only one hospital teacher to every 1,000 children in hospital. Little wonder the latest survey concludes that the extent and type of hospital teaching available differ a great deal across the country. It is found that half the hospitals in England which admit children have no teacher. A further quarter have only a part-time teacher. The special children's hospitals in major cities do best; general hospitals in the country and holiday areas are worst off. From this survey, one can estimate that fewer than one in five children have some contact with a hospital teacher--and that contact may be as little as two hours a day. Most children interviewed were surprised to find a teacher in hospital at all. They had not been prepared for it by parents or their own school. If there was a teacher they were much more likely to read books and do math or number work; without a teacher they would only play games. Reasons for hospital teaching range from preventing a child falling behind and maintaining the habit of school to keeping a child occupied, and the latter is often all the teacher can do. The position and influence of many teachers was summed up when parents referred to them as "the library lady" or just "the helper". Children tend to rely on concerned school friends to keep in touch with school work. Several parents spoke of requests for work being ignored or refused by the school. Once back at school children rarely get extra teaching, and are told to catch up as best they can. Many short-stay child-patients catch up quickly. But schools do very little to ease the anxiety about falling behind expressed by many of the children interviewed. Which of the following statements is true? A) Every child in hospital receives some teaching. B) Not enough is known about hospital teaching. C) Hospital teaching is of poor quality. D) The special children's hospitals are worst off.
