B
Have you ever dreamed of travelling in space? For many kids, staring at the stars leads to daydreams about what it would be like to be an astronaut. Just think about how amazing it would be to set foot on the moon or another planet!
Although it sounds like it would be great fun to travel to outer space, it would be a lot of work too. Travelling to outer space needs lots and lots of preparation.
Once you are in space, nothing can come on board the ship and nothing can go out. You must take all you need into outer space to keep yourself alive. Let's call these things “inputs”, including food, water and oxygen. Every input creates an output. If you open a box of cookies for breakfast, what will you do with the box when it's empty? Every piece of rubbish you create in space will remain on the ship with you. Your body will also output food and water. Since nothing can leave the spaceship, you will have to think of another way to deal with these bodily wastes.
Even breathing creates an output carbon dioxide! It's true that plants depend on carbon dioxide in the same way humans depend on oxygen to breathe. However, plants have other input needs. If you take a banana tree with you, you will need to bring enough water to keep it alive. You must also consider another type of output rubbish in the ship after taking the fruit as snacks—the banana peel.
See how carefully you have to plan for a trip to outer space? How can you plan your actions on earth to have the least influence on the environment and your future? Not only do you have to think about all the things you'll need, you will also have to consider the influence of those things because of the wastes they may create.

你曾经梦想过在太空中旅行吗？对于很多孩子来说，凝视星星会让他们产生关于成为宇航员会是什么样子的白日梦。想想踏上月球或另一个星球会是多么令人惊叹的事情啊！
虽然去外太空旅行听起来会很有趣，但这也会有很多工作要做。去外太空旅行需要大量大量的准备工作。
一旦你进入太空，任何东西都不能带上飞船，任何东西也不能出去。你必须带上所有你需要的东西进入外太空来维持自己的生命。我们把这些东西称为“输入物”，包括食物、水和氧气。每一种输入物都会产生一种输出物。如果你早餐打开一盒饼干，当盒子空了的时候你会怎么处理它呢？你在太空中产生的每一件垃圾都会和你一起留在飞船上。你的身体也会排出食物和水。由于没有东西能离开宇宙飞船，你将不得不想出另一种方法来处理这些身体排泄物。
甚至呼吸也会产生一种输出物——二氧化碳！确实，植物依赖二氧化碳，就像人类依赖氧气呼吸一样。然而，植物还有其他的输入需求。如果你带上一棵香蕉树，你将需要带足够的水来让它存活。在把水果当作零食吃了之后，你还必须考虑飞船里的另一种输出垃圾——香蕉皮。
看看你为一次外太空旅行必须多么仔细地做计划吧？你如何在地球上规划你的行动，以使对环境和你的未来的影响最小呢？你不仅必须考虑到你将需要的所有东西，你还必须考虑到那些东西的影响，因为它们可能会产生废物。
（A）6. 我们从前两段中能了解到什么？
A. 在太空旅行是具有挑战性的。
B. 在月球上生活很无聊。
C. 凝视星星很放松。
D. 成为一名宇航员很难。
（C）7. 关于太空中的输入物我们知道些什么？
A. 它会让宇航员犯困。
B. 它只意味着吃的和喝的东西。
C. 它对宇航员来说相当重要。
D. 它能帮助宇航员处理垃圾。
（D）8. 根据第三段，以下哪一个是“输出物”？
A. 一些饼干。
B. 食物和水。
C. 一个氧气面罩。
D. 空的饼干盒。
（A）9. 第四段主要讲了什么？
A. 呼吸产生输出物的原因。
B. 一种在太空中成功种植香蕉树的方法。
C. 植物依赖二氧化碳的原因。
D. 一种处理宇宙飞船中二氧化碳的方法。
（A）10. 这篇文章主要讲了什么？

B. 如何处理宇宙飞船里的废物。
C. 输入物和输出物之间的区别。
D. 在太空中处理废物的不同方法。
