Read the following article and select the best answer. Article: As many as one in five US teenagers have some degree of hearing loss, according to researchers. They say the problem is growing. "Teenagers really don't pay attention to how much noise they are exposed to ," Josef Shargorodsky of Brigham and Women's Hospital in Boston told Reuters. "Often people won't notice it, but even very little hearing loss may influence language development," said Shargorodsky, one of the researchers. The study compared surveys from the early 1990s and the mid-2000s. Each included a few thousand teenagers. In the first survey, about 15 percent of teenagers had some degree of hearing loss. Some 15 years later, that number had risen by a third, to nearly 20 percent. "This certainly is big news," said Alison Grimes, an ear doctor. "Hearing loss is very common in old people," Grimes said, but she added that it was worrying to see it happen in the younger age group. In babies and young children, hearing problems are known to slow language development. The science is less clear for teenagers, but it is easy to imagine how being hard of hearing could influence learning, said Grimes. The reasons for the rise are still unclear. When researchers asked teenagers about noise exposure - on the job, at school or from activities, for example - the teenagers didn't report any change. But Shargorodsky said that might not be true. "We know from before that it is difficult to ask this age group about noise exposure - _ " Few people would call it noise when they listen to music on their MP3 player, for example. "There is a difference between what we think is loud and what is harmful to the ear," said Grimes. Although it's not clear that the MP3 players cause teenagers' hearing loss, Grimes said it was still a good idea to turn down the sound and take short breaks from listening. Question: Which of the following is true according to the passage? - Hearing loss may lead to slow language development. - Hearing loss in old people is as common as in young people. - Researchers have already found some causes of hearing loss. - Teenagers know MP3 is harmful, but they can't stop listening to it.
Hearing loss may lead to slow language development.

While some question the necessity of such training. Many students see military training as a campus tradition that should be maintained. Early in February, the Ministry of Education issued a new regulation that colleges and universities should carry out a minimum of 14 days compulsory military training for freshmen. In a report by Beijing Evening News, Hou Zhengfang, a Beijing-based education PhD, questioned the benefits of military training. "The training routine does little to improve students' physical fitness over only two weeks' time. Maybe some disaster prevention training, such as earthquake survival or escaping from fires would be of greater benefit." Meng Yang, a 19-year-old freshman at Guangxi University, fainted during training. She said that many students, especially girls, are willing to train under direct sunshine. "For me, military training is physically challenging and even damages my health." According to Li Jian from the student affairs office of Guangzhou University, feeling dizzy happens frequently during military training and the school has received a lot of complaints from both students and parents: "But I still think military training is a good thing. Students are easier to manage after the military training. They became more positive about their new environment after the training." Although autumn is fast approaching Beijing, the noon heat burns 3300 freshmen on Tsinghua University's campus. Chu Jinjing, a freshman majoring in medicine, did feel some discomfort while training in sweaty clothes in the glaring heat, the 18-year-old still enjoyed being part of group going through strict exercises. "By going through this tough training, students bond faster and a sense of belonging to the school can be formed. I've made a lot of friends already." According to the Ministry of Education, the purpose of military training is to teach students discipline, the...

Read the following article and select the best answer. Article: Every time you visit Disney World, there's something new to see. What began in 1971 as theprefix = st1 /MagicKingdomnow includes the high-tech, movie-mad Disney and Animal Kingdom. Each time the park expands, so do your chances to spend money. How can you save? As a family guide to Disney World, I've been to the park more than 25 times with my kids, and I've developed a few money-saving plans. * Buy the five-day All-in-One Hopper Pass . Even if you're visiting for fewer days, it's a deal (the pass costs $ 229 for visitors ages 10 and up, $ 183 for kids ages three to nine and is free for kids under age three). Without the pass, you'll have to pay separately for PleasureIslandand the water parks. A single trip toBlizzardBeach, for example, would cost a family of four $ 100. * Dine out at lunch. The prices at some of the nicer restaurants, especially those in Epcot's World Showcase, are much lower at noontime than at dinner. It's wise to make reservations before you leave home. Call 407-W-DISNEY. * Become a Gold Card Member. For $65, you can get a Magic Kingdom Club Gold Card (call 1-800-56-DISNEY). Card-holders get up to 20 percent off Disney hotel rooms, plus price breaks on character breakfasts, theme park tickets and goods from Disney stores. * Don't pay extra to see a character. Character-theme dinner shows are expensive, costing a family of four about $ 140, and even a character breakfast, where Mickey or Donald Duck joins you for cakes, can _ $ 50. If your budget is tight, try to meet the characters inside the theme parks and at free in-park shows. You can watch the Diamond Horseshoe show, for example, in theMagicKingdomfor no additional cost, while the similarly themed Hoop-Dee-Doo Musical Revue requires expensive tickets. * Wait until the end of your trip to buy souvenirs. By then, the kids will really know what they want, and you won't waste money on expensive things. Question: If you are short of money, the writer suggests _ . - you should not buy things for the kids from Disney stores - you should not buy souvenirs at the beginning of the trip - you should not make a trip toBlizzardBeach - you should not have your meals out at noontime
(A).
