Great Inventions That Changed the World
Think about your daily life: the mobile phone, the keyboard, the zipper and the light bulb. None of them existed a hundred years ago. Great inventions have changed the way we live, study and work.
想想你的日常生活：手机、键盘、拉链和电灯泡。一百年前它们都不存在。伟大的发明改变了我们生活、学习和工作的方式。
Some inventions were made by accident. The zipper, for example, was invented when a man tried to help his friend close his heavy boots. By mistake, he created a new way to join two pieces of cloth.
有些发明是偶然产生的。比如拉链，是一个男人想帮朋友扣上笨重的靴子时发明的。无意中，他创造了一种连接两块布的新方法。
Other inventions came from long years of work. Thomas Edison tried thousands of materials before the light bulb finally worked. Electricity now lights up our homes, thanks to such pioneers of the industry.
另一些发明来自多年的努力。托马斯·爱迪生试验了上千种材料，电灯泡才终于成功。如今电照亮了我们的家，这要感谢这些行业先驱。
Inventions also connect the world. The telephone, invented by Alexander Graham Bell, is the father of the mobile phone. Electronic instruments and the internet make international communication easy and fast.
发明也连接世界。贝尔发明的电话是手机的前身。电子仪器和互联网让国际交流变得轻松快捷。
Every discovery starts with a basic question: why or how. National projects and laboratories help young scientists explore. Maybe one day, a new discovery made by a student like you will change the world, too.
每项发现都始于一个基本问题：为什么或怎样。国家项目和实验室帮助年轻科学家探索。也许有一天，像你这样的学生做出的新发现也会改变世界。
