Unit 6
When was it invented?
A
你好，这次我们学校的项目主题是“改变世界的小发明”。 你能帮我想一个发明吗？
我很乐意！让我想想
…
嗯
…
有啦！拉链！
拉链？它真是一项那么了不起的发明吗？
想一想在我们的日常生活中拉链使用是多么频繁。 你能看到裙子、裤子、鞋子、背包上的拉链
…
几乎无处不在！
看来你说的确实有点道理。 当然！我想到了拉链因为我上周看了一个网站。
不同发明的创始人都被列在上面。 比如它提到拉链是
1893
年被惠特科姆贾德森发明的。
不过那时它并没有被广泛利用。 真的吗？那它是什么时候开始流行的？
1917
年左右。
Hey, the subject for my school project is “Small inventions that changed the world”.
Can you help me think of an invention?
With pleasure!
Let me think...hmm...I know! The zipper! The zipper? Is it really such a great invention?
Think about how often it’s used in our daily lives.
You can see zippers on dresses, trousers,shoes,bags... almost everywhere!
Well, you do seem to have a point... 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 zipper was invented by Whitcomb Judson in 1893.
But at that time, it wasn’t used widely.
Really? So when did it become popular? Around 1917.
Good habits achieve beautiful life.
Try to be your best
