听力原文

    Before there was the written word, there was the language of dance. Dance expresses love and hate, joy and sorrow, life and death, and everything else in between. (22) Dance in America is everywhere. We dance from Florida to Alaska, from horizon to horizon and coast to coast. We dance at weddings, birthdays, office parties or just to fill the time.

    “I adore dancing,” says Lester Bridges, the owner of a dance studio in a small town in Iowa. “I can’t imagine doing anything else with my life.” Bridges runs dance classes for all ages. “Teaching dance is wonderful. My older students say it makes them feel young. It’s marvelous to watch them. (23) For many of them, it’s a way of meeting people and having a social life. ” So why do we dance? “I can tell you about one young couple,” says Bridges. (24) “They arrive at the class in a bad mood and they leave with a smile. Dancing seems to change their mood completely. ”

    So, do we dance in order to make ourselves feel better, calmer, healthier? (25) Andrea Hillier, a dance teacher says, “Dance, like the pattern of a beating heart, is life. Even after all these years, I want to get better and better. I keep practicing even when I‘m exhausted. I find it hard to stop! Dancing reminds me I’m alive. ”

24. What happened to the young couple after they attended last Bridges in class?

解析：A。本题目为细节题。问题为：那对年轻的夫妇在上完最后一节课后发生了什么事？根据原文可知，他们来到教室的时候心情很不好，但却笑着离开了。跳舞似乎完全改变了他们的心情。故正确答案为A。
