一、单词与短语在Unit4中，我们学习了一些重要的单词与短语，如"exciting"（令人兴奋的）、"fascinating"（迷人的）、"curious"（好奇的）等，这些词汇可以用来描述人或事物，增强我们的表达能力。

Unit 4 Amazing Science 神奇的科学一、Page81, Section A简，你为什么不高兴？因为昨天晚上他们不让我玩电脑游戏。

如果你在那上面花的时间太多，会危害你的健康。

也许你是对的。

（康康给简展示了一个模型。

）看这个。

哇！火箭模型！谁制作的？我制作的。

哇！它是用什么制作的？它是用金属做的。

你知道火箭是用来做什么的吗？当然知道。

它是被用来发射人造卫星或宇宙飞船的。

你说得对。

我从布朗老师那儿了解到了很多有关宇宙飞船的信息，然后我做了这个火箭模型。

我希望有一天我也能飞上太空。

我希望你的梦想实现。

二、Page83, Section B看，电灯泡！是的。

它被世界各地的人们广泛使用。

你知道它是什么发明的吗？它是1879年发明的。

它是谁发明的？托马斯·爱迪生。

据说爱迪生一生有两千多项发明。

收音机呢？收音机是1895年由古尔亚莫·马可尼发明的。

简，我们这边走。

看！飞机，但是它不同于现在的飞机。

是的。

它是由莱特兄弟在1903年发明的。

三、Page 85 Section C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。

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。

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。

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。

为你的发明制作一个模型。

看看你的发明是否像它被计划的那样起作用。
