高考真題:2011年北京卷 Part 2 (4/4)

Well, we are now looking at ways of making shopping less tiring. You know, a day at the shops wears people out. And we considered a number of ideas. Carrying shopping around is very tiring, and we looked at ways to avoid that. We thought of hiring out small electric-driven cars to shoppers, but we came up against problems of space. There just isn’t enough room. We also thought about those moving walk ways, like the ones you see at the airports. We decided it against them though, because they require a major redesign of the whole center. What we have actually come up with is a new technology where you buy what you want and then just leave it on the shelf. That way, you don’t need to carry your heavy shopping around with you all day. When you want to go home, our computer system automatically sends everything you’ve bought to your exit point, and you pick it up there.
