Well, I manage a small branch of a large supermarket, and we lose a lot of money through shoplifting. I have to try to prevent it, or else I’ll lose all my profits. A lot of shopliftings are done by teenagers in groups. They do it for fun. They’re not frightened so we have to make it difficult for them. Obviously a supermarket can’t have chains or alarms on the goods. So we have store detectives, who walk around the shop like ordinary shoppers, otherwise they’ll be recognized. We have big signs up, saying, “Shoplifters will be punished”, but that doesn’t help much. We’ve started putting cash desks at all the exits to prevent the shoplifters walking straight out with things. Of course, that worries the ordinary shopper who hasn’t found what he wanted. We also use closed-circuit television, but that’s expensive. In fact, all good methods of prevention are quite expensive, and naturally, they make our prices more expensive. But it has to be done. otherwise shoplifting itself will make all the prices much higher, and the public doesn’t want that! 二． 阅读理解
