Section C

An invention may be a new product or a new way of doing things. Inventions come about in many ways.
一項發明可以是一種新產品或者一種做事的新方法。發明會以各種方式出現。
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.
多數情況下，出現一項發明是因為有人努力去解決一個問題。有時候發明是意外的結果?？纯茨愕臅?。你有鉛筆、鋼筆、蠟筆、尺子和一些書。這些東西沒有一樣是天然存在的。它們是在工廠里制造出來，被人們發明出來的。
Inventing is interesting and exciting and everyone can be an inventor.
發明既有趣又令人興奮，每個人都可以是一位發明家。
Do you want to be an inventor? These are a few simple steps to follow in the invention process.
你想成為發明家嗎？這些是在發明過程中要經歷的一些簡單步驟。
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.
你可以有瘋狂又大膽的想法。記住沒有什么想法是愚蠢的。很多人曾嘲笑萊特兄弟，說他們永遠都飛不起來。但是他們并沒有被人們的話打擊。所以現在我們有了飛機。
Careful planning is important in the invention process. This is the time to brainstorm for idea and to evaluate them.
認真計劃是發明過程中很重要的一點。也就是說要集思廣益，評估觀點。
Make a detailed drawing of your invention so others will understand how your invention works. Make a model of your invention. See if your invention works as it is planned. If not, do more research, redesign it, and test it again.
把你的發明詳細畫出來，這樣別人就能懂它是如何運作的。為你的發明做一個模型。看你的發明是否能像計劃的那樣工作。如果不能，就繼續研究，重新設計，再次測試。
Every invention needs a name. Share your inventions with others.
每項發明都需要名字。跟大家分享你的發明。
