问题     Moods, say the experts, are emotions that tend to become fixed, influencing one’s outlook for hours, days or even weeks. That’s great if your mood is a pleasant one, but a problem if you are sad, anxious, angry or simply lonely.
    Perhaps the best way to deal with such moods is to talk them out; sometimes, though, there is no one to listen. Modern pharmacology (药理学) offers an abundance of tranquilizers (镇静 剂), antidepressants and anti-anxiety drugs. What many people don’t realize, however, is that scientists have discovered the effectiveness of several non-drug approaches to make you loose from an unwanted mood. These can be just as useful as drugs, and have the added benefit of being nonpoisonous. So next time you feel out of sorts, don’t head for the drug-store—try the following approach.
    Of all the mood-altering self-help techniques, aerobic (增氧) exercise seems to be the most efficient cure for a bad mood. "If you could keep the exercise, you’d be in high spirits," says Kathryn Lance, author of Running for Health and Beauty.
    Researchers have explained biochemical and various other changes that make exercise, compare favorably to drugs as a mood-raiser. Physical exertion (努力) such as housework, however, does little. The key is aerobic exercise—running, cycling, walking, swimming or other repetitive and sustained activities that boost the heart rate, increase circulation and improve the body’s utilization of oxygen. Do them for at least 20 minutes a session three to five times a week.
Which of the following can best describe the organization of this passage?

选项 A、A procedure is explained and its significance is emphasized.
B、A problem is examined and solutions are given.
C、Two contrasting views of a problem are presented.
D、Recent pharmacological advancements are outlined in order of importance.

答案B

解析 此题是一道涉及文章写作结构的问题,难度较大。根据文章的总体内容和作者的写作思路,我们可以看出作者是先提出一个问题:如何克服不良情绪。然后分别介绍了几种方法如药物治疗、心理治疗和增氧运动疗法等。本文重点推荐了增氧运动疗法。因此,本题的正确答案应是B。
