Hey Roy, the subject for my school project is "Small inventions that changed the world." Can you help me think of an invention?
嗨，罗伊，我的学校项目主题是《改变世界的小发明》。你能帮我想个发明么？
My pleasure! Let me think ... hmm ... I know! The zipper!
我很乐意！让我想想...嗯...我知道啦！拉链！
The zipper? Is it really such a great invention?
拉链？这真的是个伟大发明么？
Think about how often it's used in our daily lives. You can see zippers on dresses, trousers, shoes, bags ... almost everywhere!
你想想在日常生活中我们经常用到拉链。裙子、裤子、鞋子、包包...它们几乎无处不在！
Well, you do seem to have a point ...
确实有道理...
Of course! I thought about it because I saw a website last week. The pioneers of different inventions were listed there. For example, it mentioned that the zipper was invented by Whitcomb Judson in 1893. But at that time, it wasn't used widely.
当然！我想到拉链是因为上周我在一个网站上看到了。网站上列出了不同发明的发明人。例如，上边提到拉链是威特康·朱迪森在1893年发明的。但当时还没有被广泛使用。
Really? So when did it become popular?
真的么？那什么时候拉链才开始流行的呢？
Around 1917.
大概在1917年。
