Back in the early 1960s, when the laser【C2】______developed, it was viewed by some as a fascinating research tool; others called it a【C3】______toy. Since that time, the laser has proved to be an【C4】______of many uses. In fact, in many places it’s becoming a part of【C5】______life. Take, for example, what’s happening at some supermarkets. Food-shopping Americans are coming【C6】______with lasers and computers for the first time. But they’re hardly【C7】______it, until they get to the checkout line. With scarcely a glance at the items, the clerk【C8】______them across a hole, where a special marking on each item is scanned by a low-powered laser【C9】______inside the machine, connected to a remote computer. It started a few years ago, when food processors【C10】______the time had come to put code markings on every one of their thousands of food products.
