【答案解析】[解析] 男士答：“我家离公司很近(a stone's throw)”，可知，他不开车是因为公司离他家不远。
[听力原文] 15-18
W: Peter, where is the ear? I haven't seen you drive to work for a long time! Is it broken or stolen?
M: Hi, Susan] Oh, no! Of course not! I give up driving to work. Instead, I ride to my working place.
W: Why is that?
M: You see. There is only a stone's throw from my home to my working place. I think riding a bike to work is more convenient.
W: I don't think so. It will take you at least 25 minutes to get to our company from here.
M: Yes, sometimes, 30 minutes. But I love riding to work now. It is a totally different picture on my way to work.
W: Why do you think so?
M: You see, every morning, after I set off for work, I can breathe the new fresh air along the way. By the time I reach my office, I feel rather revived. I even don't rely on coffee to spend my morning hours.
W: Is it so magical?
M: At least, that's how I feel about riding to work. I can't believe I have wasted so much fresh morning air in the past 3 years!
W: Will you continue riding to work in the future?
M: I think so.
