Ⅱ.Reading comprehension.
Barcode（条形码）technology makes shopping in stores faster and easier. The idea began in 1971, when an engineer created a special code. Before barcodes, shop workers had to add up prices by hand one by one. But now with barcodes, their work becomes faster.
Time has shown that barcodes are a wonderful invention. Today, they are scanned（扫描）more than 6 billion times every day, and around 2 million companies worldwide count on them.
A barcode carries lots of useful information, such as where a product is from, its price, and more. It also helps stores record their stock. For example, if a store has 10 boxes of milk and a customer（顾客）buys one, the barcode can help record the number. Then the store owner can know there are 9 boxes left.
The next generation of barcodes, like QR codes, can hold even more information. With just a quick scan using a smartphone, they can gather more information about the products. In this way, shoppers can make smarter choices.
Barcodes have truly changed our lives. They save us time and make our daily life much more convenient in ways we might not even notice!
