Section C
An invention may be a new product or a new way of doing things. Inventions come about in many ways.
一项发明可以是一种新产品或者一种做事的新方法。发明会以各种方式出现。
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.
多数情况下，出现一项发明是因为有人努力去解决一个问题。有时候发明是意外的结果。看看你的书包。你有铅笔、钢笔、蜡笔、尺子和一些书。这些东西没有一样是天然存在的。它们是在工厂里制造出来，被人们发明出来的。
Inventing is interesting and exciting and everyone can be an inventor.
发明既有趣又令人兴奋，每个人都可以是一位发明家。
Do you want to be an inventor? These are a few simple steps to follow in the invention process.
你想成为发明家吗？这些是在发明过程中要经历的一些简单步骤。
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.
你可以有疯狂又大胆的想法。记住没有什么想法是愚蠢的。很多人曾嘲笑莱特兄弟，说他们永远都飞不起来。但是他们并没有被人们的话打击。所以现在我们有了飞机。
Careful planning is important in the invention process. This is the time to brainstorm for idea and to evaluate them.
认真计划是发明过程中很重要的一点。也就是说要集思广益，评估观点。
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.
把你的发明详细画出来，这样别人就能懂它是如何运作的。为你的发明做一个模型。看你的发明是否能像计划的那样工作。如果不能，就继续研究，重新设计，再次测试。
Every invention needs a name. Share your inventions with others.
每项发明都需要名字。跟大家分享你的发明。
Section D
Where Are We?
我们在哪里？
Where are we?
我们在哪里？
That was a big question when we first explored our world long ago.
很久以前人们刚开始探索世界的时候这是一个很困难的问题。
The early explorers found that the stars in the sky were good guiding marks.
早期的探索家发现天空中的星星是很好的标记。
Using the stars, they could find out where they were and in which direction they were going.
通过星星，他们能够知道自己在哪里，在往哪个方向前进。
This method worked well at night as long as the weather was good and the stars could be seen.
只要天气晴朗，星星清晰可见，这种方法就很有效。
But it didn't work so well during the rest of the time.
但是其他时间效果就不太好了。
That was a problem.
这是个问题。
Today, the problem has been solved by the Global Postitoning System(GPS).
现在，这个问题已经被全球定位系统（GPS）解决了。
It is like a man-made star.

它还可以用来研究地球的形状。
The GPS is a great invention that helps us explore our planet and discover where we are.
全球定位系统是一个很伟大的发明，能够帮助我们探索地球，寻找位置。
