An invention may be a new product or a new way of doing things. Inventions come about in many ways. Most of the time, inventions happen because someone works to solve a problem. Sometimes inventions are the result of accidents. Look at your schoolbags. You have pencils, pens, crayons, rulers and some books. None of these things was planted in fields. They were made in factories and invented by someone. Inventing is interesting and exciting and everyone can be an inventor. Do you want to be an inventor? There are a few simple steps to follow in the invention process.

一项发明也许是一个新的产品或者一种做事情的新方法。发明以许多方式出现。大多数时候，有人为了解决问题而工作，发明就偶然出现了。有时候发明是事故的结果。看看你的书包。你有铅笔、钢笔、蜡笔、直尺和一些书。这些物品没有一个是被种在田地里的。它们是工厂里制造的而且是由某个人发明的。发明东西是有趣和令人兴奋的，而且每个人都能成为一个发明家。你想成为一个发明家吗?在发明的过程中有几个简单的步骤要遵从。

You can have wild and crazy thoughts. Remember that no idea is too silly. Many people laughed at the Wright brothers and said they would never fly. But they weren’t discouraged by what people said. That’s why now we have planes.

你可能有疯狂的想法。记住有想法就好。许多人嘲笑莱特兄弟并且说他们将永远也飞不起来。但是他们没有因为人们所说的而灰心丧气。因此，我们现在才有飞机。

Careful planning is important in the invention process. This is the time to brainstorm for ideas and to evaluate them.

在发明的过程中认真计划是重要的。这时候要多想出一些想法并评价它们。

Make a detailed drawing of your invention so others will understand how your invention works. 为你的发明画一个详细的图纸，使他人明白你的发明是怎样工作的。

Make a model of your invention. 为你的发明制作一个模型。

See if your invention works as it is planned. If not, do more research, redesign it, and test it again. 看看你的发明是否像它被计划的那样起作用。如果不是，就做更多研究重新设计，并再次试验。

Every invention needs a name. 每个发明都需要一个名字。
