Article: New findings show that musical training affects the structure and function of different brain areas, how those areas communicate during the creation of music, and how the brain interprets and combines sensory information. The findings were presented at Neuroscience 2013, the annual meeting of the Society for Neuroscience and the world's largest source of emerging news about brain science and health. These views suggest potential new roles for musical training including training plasticity in the brain, offering an alternative tool in education, and treating a range of learning disabilities. Today's new findings show that long-term high level musical training has a broader effect. Researchers found that musicians have a better ability to combine sensory information from hearing, touch, and sight. The age at which musical training begins influenced brain structure and its function. Beginning training before the age of seven has the greatest effect. Even older adults who took music lessons as children but haven't actively played an instrument in decades have a faster brain response to a speech sound than those who never played an instrument, according to a study appearing November 6 in the Journal of Neuroscience. The finding suggests early musical training has a lasting, positive effect on how the brain deals with sound. "Playing a musical instrument is a multi-sensory and motive experience that creates emotions and movements--from finger tapping to dancing -- and engages pleasure and reward systems in the brain. It has the potential to affect brain function and structure when done over a long period of time," said Gottfried Schlaug, MD, PhD, of Harvard Medical School, press conference speaker, also an expert on music. "As today's findings show, musical training brings about new processes within the brain, at different stages of life, and with a range of effects on creativity, cognition , and learning," he added.
Question: Why does the author mention "Even older adults ... a speech sound." in Para. 3?
Options: (A) To suggest how new roles for musical training work. (B) To prove early musical training affects the function of the brain. (C) To explain how the brain interprets sensory information. (D) To show how the brain areas communicate in music training.

B

Article: Today's career assumption is that you can get a lot of development, challenge and job satisfaction and not necessarily be in a management role. Managing others is always a tough task, but in the past that stress was balanced by hopes for career mobility and financial rewards. Along with a sizable pay raise, people chosen as managers would begin a nearly automatic climb up the career ladder to successful executive private benefits: company cars, club memberships, plus the key to the executive washroom. But in today's global and more competitive showground, a manager sits in an insecure chair. More companies has begun to take less management as they come to view their organizations as collections of talents rather than hierarchies . There are far fewer steps for managers to climb. Also, managerial jobs demand more hours and headaches than ever before but offer slim, if any financial paybacks and perks. Now managers must manage many people who are spread over different locations, even over different continents. They must manage across functions with, say, design, finance and marketing. In many companies, when the most praised people in business are those launching something new, management seems like an invisible, thankless role. Employers are looking for people who can do things, not for people who make other people do things. Moreover it may not pay to be a manager, at least not the way it once did. Ms. Chmielewski says, "The emotional rewards can be great, and there were times when I enjoyed management. But a 10-to-11-hour day and one weekend day a month is the norm ". With more people cautious of joining management, are companies being hurt or worrying about developing future leaders? Not many are. While employers have fired a lot of managers, they believe many more candidates linger on at many companies. "Another reason why companies aren't short of managers," argues Robert Kelley, a business professor, "is that so many workers today are self-managed, either individually or via teams, they don't need a manager."
Question: By writing the passage, the writer seems to _ .
Options: (A) explain reasons for firing managers (B) advise people not to become managers (C) express dissatisfaction of some managers (D) encourage managers to be more competitive

B

question:
Article: Some weightloss camps, which are rare in China just a few years ago,have multiplied in Beijing, Qingdao, Shenzhen,and other cities. Today about 15 percent of adults, or 200 million Chinese, are reportedly overweight.Of these, 90 million--about 7 percent--are obese . Experts say the obesity epidemic is spreading to children, though more slowly than in adults. The obesity, they say, will do harm to the health of China' s citizens and economy."We're seeing a very large number of teenagers who are quite heavy and aren't moving much," said Barry Popkin, a nutrition professor. Popkin carries out an ongoing healthandnutrition survey of 16,000 households in China. He says more kids today are overeating and putting on weight "quite quickly." In just ten years China's childhood obesity rate has doubled,with the greatest gains coming in urban areas."In big cities it's a big problem." Some experts blame the extra fat on a range of factors, many of them tied to China' s rapidly changing economy and culture. The diets of Chinese adults and children are far higher in meats, fish, eggs, dairy products, fats and sugars than ever before. In addition,kids--especially city dwellers--are more today and spend more time indoors in front of homework, television,computer games, and the Internet. Shuwen Ng,a health economist, says that kids in China now have pocket money, and they spend a portion of it on junk food. Ng adds that advertising and peer groups influence kids' food choices. Certain foods, such as new candies or fast food, have attractive features. China' s childhood obesity rate stillfall behind that of the United States, where some 15 percent of kids are said to be obese. But the longterm effects are equally serious.
Question: According to the passage we know _ .
Options: (A) weightloss camps have been very popular in China six years ago (B) about 290 million Chinese are overweight in China in all (C) in China childhood obesity rate in rural areas is lower than that in major cities (D) America' s childhood obesity rate is lower than China's

C
