【正确答案】 B

【答案解析】[听力原文] Interviewer: How many hours do you spend on Internet everyday? David: I spend about 1 to 3 hours on school day working and probably about half an hour just surfing. And on a weekend, I would spend about 2-10 hours working and about two hours surfing or so. I try to limit my time. I don't want to get addicted to the Internet. Interviewer: You do all the design work? David: Yes, the design, the programming. My father handles the marketing. He markets the company very well actually. And if you go to any major search engine such as Yahoo or Google, and type in web designing company or Macromedia Flash, we will come in the top 10 with his marketing. Interviewer: And do you know those marketing things? David: He is teaching me. He is training me for that when I am older actually, so I don't have to be reliant on anybody. Interviewer: What would you do if people don't treat you as a grown-up? If they don't take you seriously, what would you do? David: I simply let them go. You can't do business with someone who doesn't take you seriously. Interviewer: Do you care how people look at you? David: No, not really. If you care too much about what people think of you or look at you, I don't think you can live a joyful life. Interviewer: Then, have you ever thought of doing business with China? David: Of course, that's the main reason we are here. To hopefully make some bids and do business in China, and make some long term relationships with us and Chinese businesses that look to grow bigger, because currently, as I mentioned, China is not developed to its fullest potential, and some of the smaller companies will grow. And we want to be part of that. 根据对话中probably about half an hour just surfing可知花半小时浏览网页。
