【正确答案】 C

【答案解析】[听力原文] W: Good morning, Mr. Smith. May I join you on the walking exercise? I thought it is a good idea to walk around to get some fresh air early in the morning. M: Do come along. It is nice to have some company for good exercise. My wife comes along with me sometimes but she is quite irregular. We have a large family and she has to prepare breakfast for the children and for me. W: Do you take walking exercise every morning? M: Yes. I feel much better after a good walk in the morning. I have to sit at a desk the whole day. Some exercise before going to work helps. It clears my head and puts vigor into my body. W: Some people prefer to take an evening walk after dinner. M: I get fairly late coming back from office. Then I have my little son with his lessons in the evenings. W: These days, fitness walking is getting very popular. Nearly all men come out for fitness walking between five and six in the morning. M: I notice that they are the middle-aged and older people, who are out walking in the morning. They understand the importance of morning exercise. W: Yes, it seems like that. The young white collars go to parties after work so often that they can hardly get up early in the morning. That is the reason for their absence from fitness walking. M: Also perhaps they are in the prime of life and do not feel the strain like us older men. W: You said it. M: Well, today's walking exercise was very refreshing and informative. I must go home now and get ready for work. See you tomorrow again for morning exercise.
