【正确答案】 C

【答案解析】 [听力原文]
   W: Bill, I've got a question. What I don't really understand and nobody seems to be able to explain it to me is this: how are our lives any easier now than they used to be? Everything just seems to get more and more complicated.
   M: Okay, Jane, I'll give you an example—take my iPhone 7. If I didn't have it I wouldn't be able to keep in close touch with my friends and colleagues.
   W: What's wrong with writing email letters to them?
   M: You mean sending email letters over the Internet?
   W: Of course. I still write regularly to friends I've known for years.
   M: And so do 1, when I'm not pushed for time. But sometimes I need an immediate reply to a question. I can't wait, especially if I'm writing to someone in Australia or the Far East.
   W: You could use the phone, couldn't you?
   M: Well, I could, but it'd work out much more expensive and anyway I don't want a nice cosy chat with these people. I often just want the answer to a question.
   W: Everyone's in such a hurry these days. They drive everywhere—they don't even think of walking or cycling. It's no wonder they're stressed and overweight.
   M: But cars save you so much time, I mean, to walk to work would take me 45 minutes, whereas I can just get in my car and be there in ten. Think of all the time you could save.
   W: And what do you do with all that time you've managed to save?
   M: That's the whole point—you've got a choice. You can do what you like—listen to music, watch a DVD, or surf the Internet and so on.
   W: I'd have thought walking was more relaxing—you haven't got to worry about being held up in traffic jams, or accidents or foul weather.
   M: You've got a point there, Jane. Things are getting pretty bad on the roads at certain times—people do get very stressed and irritated when they get held up.
   W: But you still haven't told me what you do with all the time you've saved, Bill.
   M: I suppose in the end you get more spare time for yourself—time to go out and enjoy yourself: go to the gym to keep fit; watch TV; play computer games. Or you can chat to your friends on the phone or text someone on Wechat.
   W: I don't understand: How do you text someone? Is it like writing an email letter?
   M: Not really, Jane. To get onto the WeChat network, you need a suitable smart phone with app installed. You key your message into your phone and then send it—you can send photos or videos as well. You can even become WeChat Out users to receive free calling credit. That certainly saves you a great deal of cash on phone bills...
   W: Oh, stop, stop—it's all too much for me—I think I'll just settle for what I've got.
   What is Jane complaining about?
