本文介绍了日常生活中几种源于意外的发明。牛仔裤最初是工人服装，后风靡全球；烟花由中国厨师偶然混合厨房用品制成；创可贴因妻子常切伤手指而被发明；微波炉则源于工程师发现微波能融化糖果。这些故事表明，许多日常用品的诞生都来自生活中的意外发现，展现了人类善于观察与创新的精神。
Do you notice the everyday things around you, such as jeans, fireworks (烟花), the Band-Aid (创可贴) and the microwave oven?
你注意到身边的日常物品了吗，比如牛仔裤、烟花、创可贴和微波炉？
Many inventions in our everyday lives come from accidents. Take a look at a few of them. You may be surprised.
我们日常生活中的许多发明都源于意外。来看看其中几个吧，你可能会感到惊讶。
Now, we wear jeans all the time, but, at first, they were only for workers. Jeans are hard to wear out (穿破). Later, more and more people liked them and wore them, too. Jeans became popular around the world.
如今，我们随时穿着牛仔裤，但最初它们只是工人的服装。牛仔裤很耐穿（不易穿破）。后来，越来越多的人喜欢并穿上它，牛仔裤风靡全球。
Fireworks are fun and colorful. However, when you see them, do you think of a cook? A Chinese cook invented fireworks in old times. He mixed a few kitchen things together by accident. The mixture burnt and made a beautiful light.
烟花有趣又多彩。然而，当你看到它们时，会想到厨师吗？古代一位中国厨师偶然将几种厨房用品混合在一起，混合物燃烧后发出美丽的光芒——这就是烟花的起源。
The invention of the Band-Aid was also a surprise. About 90 years ago, American Earle Dickson made the first Band-Aid. His wife was always cutting her fingers in the kitchen. Dickson wanted to make something to help his wife bandage (包扎) herself up. So, he used a piece of gauze (纱布) and put it on some tape (胶布). Now, Band-Aids are a part of our daily lives.
创可贴的发明也出人意料。大约90年前，美国人厄尔·迪克森制作了第一个创可贴。他的妻子常在厨房切伤手指，迪克森想帮她自行包扎伤口。于是，他用一块纱布贴在胶带上——如今，创可贴已成为我们日常生活的一部分。
Nowadays, microwave ovens are popular around the world. But, in the beginning, people used microwaves in the war. American Percy Spencer found that microwaves could cook. He felt a candy in his pocket melting (融化的) when he worked beside the microwaves. Spencer then did many tests to prove (证明) his idea. In 1947, the first microwave oven in the world came out.
如今，微波炉在全球广受欢迎。但起初，微波技术用于战争。美国工程师珀西·斯宾塞发现微波能加热食物——他在微波设备旁工作时，口袋里的糖果竟融化了。随后他通过多次实验验证了这一想法。1947年，世界上第一台微波炉问世。
