Universal Product Code What are the zebra stripes （See the figure) on the Instant Mashed P

Universal Product Code

What are the zebra stripes (See the figure) on the Instant Mashed Patato Flakes package？ They are special black and white vertical lines. These black and white stripes can be read by an optical scanner, or computer. The "scanner", which reads the lines of code, is a small laser beam of light. When the light rays is broken by the black stripes, the computer "reads" the information about the product.

This code is called the Universal Product Code (UPC). It is designed to add speed and efficiency to stores by using computers. It can do this in several ways. First, it is not necessary for workers to put individual prices on items. By using UPC, the computer can print out the accurate price of the item. Errors in prices are eliminated, or done away with. Also, the time spent checking out is reduced UPC gives an itemized receipt to the customer with all the items, prices, and totals. The store clerk does not need to spend time checking the price on the item and punching it into the cash register. This UPC computerized system will probably save as much as 45 percent of the checkout clerk's time.

What do the stripes mean？ How does the computer interpret the stripes？ The number printed below the vertical bars identifies the manufacturer and the manufacturer's item. As many as 10 trillion individual machine-readable numbers can be used with this system. In the example, the 0 on the left side means that it is a grocery item. The numbers 36800 indicate the manufacturer, in this case it is the Food Club Company. The last five digits, 51512, mean it is a pack of mashed patato flakes. The light rays from the light beam read these lines, and the message is sent directly to the computer. The computer then finds the information about this product (price, inventory data) and sends it instantly back to the terminal at the checkout counter. At the same time, it keeps an inventory for the store manager. Many products have labels with these stripes.

The figures printed below the stripes are codes of the producer and the product.

A．right

B．wrong

C．Doesn't say

Computers can injure you. 电脑会伤害到你。Most other injuries happen suddenly. For example，

if you fall off a bike and break your arms，it happens very quickly. But computer injuries happen slowly. You probably know how to ride a bike safely. Now learn to use a computer safely. Your eyes Too much light can injure your eyes，so never sit too close to a computer screen. Your eyes should be at least 50cm from the screen. Remember to look away from it sometimes. This gives your eyes a rest. When you use a computer, the window should be on your left or your right. If it is behind you, the light will reflect on (反射) the screen. If the window is in front of you, the sun and the screen will both shine into your eyes. Your hands and wrists Hand and wrist injuries can happen because the hands and wrists are moved in the same way hundreds of times. If you use a keyboard for a long time，follow these three rules:1) Rest your wrists on some thing. 2) Keep your elbows (肘) at the same height as the keyboard. 3) Stop sometimes and exercise your hands，wrists and fingers in a different way. Your back Some people sit for many hours in front of a computer. If you sit in the wrong way，you can injure your back or your neck. So you should sit with your back straight. The top part of the screen should be in front of your eyes. Your forearms，wrists，hands and the upper part of your legs should all be parallel (平行) to the floor. If you are sitting for a long time，get up every 30 minutes and exercise your arms，legs and neck. Enjoy your computer，but use it safely. 问题：A computer screen may injure your eyes if your eyes are too close to it.A.T
