常春藤解析英语【5】I Didn't Know That.　我不知道（在线收听）

by Jerri Graham

How much do you know? Once you watch National Geographic Channel's I Didn't Know That, you will be surprised at how little knowledge you actually have. This 10-part series is packed with action as it explores dozens of minute facts about everyday items. All of these ordinary things that we use on a daily basis may not appear exciting, but once National Geographic Channel shines the spotlight on them, you'll never see them in the same way again.

Money makes the world go round. We all use it, need it, and want more of it. Did you know that the average bank note has microscopic grains of cocaine on it? Yes, that's right. Cocaine! This illegal drug can be found in small amounts on a $100 bill. Speaking of cash, the Aztecs didn't use paper money the way we do nowadays. Instead, they used cocoa beans. The same beans that are used to make hot chocolate were once the main currency for these people. Just imagine; you could actually drink away your entire allowance.

In most offices, you'll see desks, computers, and chairs. Those office chairs get a lot of use throughout the course of a lifetime. Office chairs must be durable and have the ability to stand up to the pressure of being sat on 5,000 times a year. In order to test their durability, a fake butt mechanically sits in a chair some 50,000 times.

After meals, most people brush their teeth. In a person's lifetime, this toothpaste adds up to some 80 liters. If you're short on cash, you could always make your own toothpaste. All you need are five ingredients — baking soda, salt, glycerin, water, and peppermint. Once you've finished brushing your teeth, you could also use the toothpaste to polish your silver.

Yes, money may make the world go round, but trivia about everyday items in our lives makes the world much richer. After watching these 10 episodes, you won't be able to say, "I didn't know that!"

中文翻译＆标准答案

你知道的事有多少？看了国家地理频道全新系列 I Didn't Know That 后，你会惊讶地发现自己拥有的知识少得可怜。这个系列分成十个单元，探索生活用品的同时，又让节目充满动感。我们每天所用的这些普通用品也许并不起眼，但是经过国家地理频道的『加持』，会让你用不同以往的眼光来看待。
　　
有钱能使鬼推磨。我们都会使用钱、需要钱，也想要得到更多的钱。但你知道一般的银行钞票里含有极少量的古柯碱吗？没错，就是古柯碱！百元钞票里就含有这种少量非法药物。说到钱，阿兹提克人不像我们现代人一样使用纸钞。相反地，他们使用可可豆。这些用来泡热巧克力的豆子曾经是这些人主要的货币。想象一下，你可以真的喝掉你的零用钱。
　　
在大部分的办公室里，你会看到桌子、计算机和椅子。这些办公室椅子在一生中会被坐很多次。它们必须很耐用，并且能承受一年被坐上五千次的压力。为了测试其持久性，会用一个假屁股机械性地坐椅子约五万次之多。
　　
多数人餐后会刷牙。一个人一辈子用掉的牙膏多达八十公升。假如你缺钱的话，也可以自己做牙膏。只要有五种成分即可：食用苏打、盐、甘油、水和薄荷。你刷完牙后还可以用牙膏来擦拭银器。
