去外太空旅行你會(huì)帶什么？

侯怡

Have you ever dreamed of traveling in space？ Like most kids， when you look at the stars， youll imagine that you will be an astronaut1. It would be lots of fun to travel on a spaceship， just think about how wonderful it would be to stand on the moon or another planet！

你夢想過去太空旅行嗎？和大多數(shù)孩子一樣，當(dāng)你仰望星空時(shí)，會(huì)想象自己是一名宇航員。乘坐宇宙飛船去外太空旅行會(huì)十分有趣，想想看，站在月球上或者其它星球上的感覺是多么美妙啊！

Of course， its not easy to become an astronaut. There arent many astronauts in the world， so you have to learn many skills in different areas. Astronauts have many skills so that they can be suitable2 to be traveling scientists beyond Earth.

當(dāng)然，成為一名宇航員并不是件容易的事情。世界上的宇航員數(shù)量不多，所以你得學(xué)習(xí)不同領(lǐng)域的技能。宇航員擁有多種技能，這樣他們才有資格成為地球外太空旅行的科學(xué)家。

Although it sounds like it would be great fun to travel to outer space， there would be a lot of work to do. You should take lots of preparation if you want to travel to outer space. Everything has to be planned carefully in advance. Why？ Because once you leave Earths surface， youll be all alone with the things you have in your spaceship. Theres no store to go to in space！

盡管去外太空旅行聽上去很有意思，但是你得完成許多工作。如果你想去外太空旅行，那就要做許多準(zhǔn)備，每件事都要提前仔細(xì)計(jì)劃好。為什么呢？因?yàn)橐坏┠汶x開地球表面，就只能與你的行囊為伴。太空中可沒有商店！

Once you are in space， nothing can enter the ship and nothing can go out. You must take everything you need to survive3 into outer space with you. Lets call these items “inputs4”. Inputs might include necessities such as food， water and oxygen.

一旦你待在太空中，就沒有什么東西可以進(jìn)出飛船。你必須把所有維持生命所需的東西帶到太空中。我們稱這些東西為“攝入物”，攝入物可以包括食物、水和氧氣等必需品。

Now lets talk about “outputs5”. Every input creates an output. Lets say you open a box of Coco Comets cereal6 for breakfast. What will you do with the box when it is empty？ You only have so much room to store outputs on your spaceship. The garbage7 you create will be on the ship with you. Where will you store the garbage？

接下來我們談?wù)劇芭判刮铩薄Ｃ糠N攝入物都會(huì)產(chǎn)生排泄物。比如說，你打開了一盒可可彗星牌的谷物作為早餐，如果盒子里的食物吃完了，你會(huì)怎么處理這個(gè)盒子？而你的宇宙飛船上只有那么點(diǎn)空間存放排泄物，你產(chǎn)生的垃圾只會(huì)和你一起留在宇宙飛船上。你會(huì)把這些垃圾放在哪里呢？

In order to survive， you must eat and drink， but this means your body will also turn these food and water into other forms8 of waste. Because nothing can leave the spaceship， you will need to think of a way to handle these bodily wastes. It might seem disgusting9， but this is an important question.

為了生存，你必須攝取食物和水，但是這就意味著你的身體會(huì)將這些食物和水轉(zhuǎn)化成其它形式的垃圾。由于任何東西都不能離開宇宙飛船，你得想辦法處理這些身體代謝產(chǎn)生的廢物。這或許很惡心，但是個(gè)很重要的問題。

Even breathing creates an output—carbon dioxide！Do you know how to deal with the carbon dioxide？ Hint： Plants love carbon dioxide and depend on it. Also， plants output oxygen！ However， plants also have other input needs like water.

即使呼吸也會(huì)產(chǎn)生排泄物，那就是二氧化碳！你知道如何處理二氧化碳嗎？給你個(gè)提示：植物喜歡二氧化碳并且依賴于它。同樣地，植物也產(chǎn)出氧氣！但是植物還需要其它的攝入物，比如水。

So， you have to plan for the trip to outer space very carefully. You have to think about all the things youll need， and you also have to consider what wastes these things will create.

所以說，你得仔細(xì)計(jì)劃好外太空的旅行，還得想清楚所有需要的東西，以及這些東西會(huì)產(chǎn)生的廢物。

Packing for a trip to outer space isnt a simple thing. It will take you time and energy. And you can start right now！Perhaps， you should make a plan that will have the least influence10 on the environment and your future.

去外太空旅行之前打包行李不是件容易的事。這需要時(shí)間和精力，而且你現(xiàn)在就要開始準(zhǔn)備了！或許，你該先做個(gè)計(jì)劃，這個(gè)計(jì)劃對(duì)環(huán)境和你的未來的影響應(yīng)該是最小的。
