【答案解析】[听力原文] 29-31
Biologically, there is only one quality which distinguishes us from animals: the ability to laugh. And it is a luxury-, for unlike any other bodily process, laughter does not seem to serve a biologically useful purpose. In a divided world, laughter is a unifying force. Human beings oppose each other on a great many issues, but we all share the ability to laugh. And laughter, in turn, depends on that most complex and subtle of all human qualities : a sense of humor. This can best be seen from the world-wide popularity of Charlie Chaplin's early films. The little man at odds with society never fails to amuse no matter which country we come from. Dr. Samuel Johnson, a great commentator on human affairs, once remarked, " Men have been wise in very different modes; but they have always laughed in the same way.
A sense of humor and laughter may take various forms, but the effect is always the same. The sense of humor must be singled out as man's most important quality because it is associated with laughter. And laughter, in turn, is associated with happiness. Courage, determination, initiative--these are qualities we share with other forms of life. But the sense of humor is uniquely human. If happiness is one of the great goals of life, then it is the sense of humor that provides the key.
29. How does the speaker evaluate laughter in a divided world?
[解析] 细节题。本文介绍笑声与幽默感的重要性。根据选项可以预测问题是有关某事物的作用或者性质。文章开头就提到了laughter，应该考虑与选项中的it相关。听到选项中涉及的distinguishes、luxury、unifying时，与原文进行信息匹配，结果C中的power相当于原文的force，A、B与原文信息均有出入，故答案为C。
