A
An American housewife was pushing her basket with one hand. With the other hand she was holding on to her small child. She arrived at the checkout(付款)counter and thought, !Now another 20 minutes. But her bill was ready in 20 seconds.
Twenty seconds? Yes. A new electronic(电子的)system !reads a small stamp of black and white lines on each tin, box or bottle. These little lines give the computer all the information it needs-the kind of product, the price and the tax. The girl at the counter simply moves the groceries(食品杂货)along in front of the eye of the machine. And the bill is ready in no time. Most people are very pleased with this new idea. The machines-now in 20 supermarkets in New York, U.S.A.-save a lot of time and money. And they dont make as many mistakes as people. Some shoppers, however, are complaining(抱怨).They cant read the price of the food on a tin and all they can see is little black and white lines. The prices are on the shelves but they want them on each tin. Many people arent sure that machines are honest shopkeepers! The new machines are very expensive. But everyone, even these worried shoppers, will be happy. In the end, they bring food prices down.
