问题     The guy in the next cubicle is yammering away on the phone. Across the room, someone begins cursing loudly at a jammed copy machine. The headphones on the other end of your desk suddenly look very appealing. Would anyone mind if you tapped into your iTunes playlist for a while? Some workers like to listen to music when they find themselves losing focus. They may also plug in their earbuds to escape an environment that’s too noisy—or too quiet—or to make a repetitive job feel more lively.
    In biological terms, melodious sounds help encourage the release of dopamine(a chemical found in brain)in the reward area of the brain, as would eating a delicacy, looking at something appealing or smelling a pleasant aroma, said Dr. Amit Sood, a physician of integrative medicine with the Mayo Clinic. People’ s minds tend to wander, "and we know that a wandering mind is unhappy," Dr. Sood said. "Most of that time, we are focusing on the imperfections of life." Music can bring us back to the present moment. "It breaks you out of just thinking one way," said Teresa Lesiuk, an assistant professor in the music therapy program at the University of Miami. Dr. Lesiuk’s research focuses on how music affects workplace performance. In one study involving information technology specialists, she found that those who listened to music completed their tasks more quickly and came up with better ideas than those who didn’t, because the music improved their mood.
    Dr. Lesiuk found that personal choice in music was very important. She allowed participants in her study to select whatever music they liked and to listen as long as they wanted. Those who were moderately skilled at their jobs benefited the most, while experts saw little or no effect. And some novices regarded the music as distracting. Dr. Lesiuk has also found that the older people are, the less time they spend listening to music at work.
    Few companies have policies about music listening, said Paul Flaharty, a regional vice president at a staffing agency. But it is still a good idea to check with your manager, even if you see others wearing headphones in the office. For those who choose to listen to music, it’s best to set limits, because wearing headphones for an entire shift can be perceived as rude by those nearby.  
Which of the following is an effect of music according to Paragraph 2?

选项 A、Making people’ s mind wander.
B、Bring people to their unhappy moment.
C、Making people focus on the imperfections of life.
D、Improving people’ s mood.

答案D

解析 根据题干关键词定位到第二段。题目要求为“哪一项是音乐的作用”。第二段最后一句“because the music improved their mood”与D项相符,因此D项为正确选项。A项“使人们分神”,B项“将人们带人不快乐的时刻”,C项“使人们关注生活的不完美”均不是第二段所提到的音乐的作用。因此选择D项。
