历史 第九篇(发明是)讲义P117
But too often it seems to me, we apply the turn (term 术语) “invention” only to big, important items like the car or the telephone. AR (After all), we can hardly imagine surviving without them. We don’t stop to think there are L (literally 如实的) hundreds of inventions that make our lives little easier, little more convenient.
Let’s take something as common as the paper bag on my desk here. Yes, that’s right. I’ve got my lunch in it. Well, I never open my lunch bags without thinking of Charles Stilwell, who in 1813 invented the first machine to produce bags like this. You see, before Stilwell, bags were pieced together by hand, and they didn’t have flat bottoms, so they could stand on their own, and you couldn’t fold them very well, either. Stilwell changed all that with what is really a MA (marvelous 令人惊叹的) piece of engineering. Think about it. Look at how efficiently this bag is designed. I can open it with a flick of my rest. But I can also fold it back flat as a piece of paper. And I can scroll (store) a hundred of them onto (under) my desk. What’s more, it’s strong. See? I can even put this heavy dictionary in it, and it won’t break. But it’s cheap to produce, really. It’s a masterpiece 杰作 of practical engineering. Girls restores buy (Grocery 食品杂货店stores buy) over a billion of them every year. Well, nobody remember Stilwell nowadays, but his little invention has certainly proved useful. If any of you can produce something perhaps useful, you have really done something.
