I have a funny question for you: Have you ever heard a cow burp? 你有聽過牛打嗝嗎？ Yes, cows burp. They burp a lot! A cow burp probably sounds like this… Oh, wait. That's a moo. Here's a burp… Maybe you've heard a cow burp. But have you ever seen a picture of a burp? 你可能聽過牛的打嗝，但是你有看過牛打出來的嗝的照片嗎？ Yes, you can take a picture of a burp. But, you need a special camera. Scientists in America used a special camera to take pictures of cow burps. The camera was in space! 美國科學家用外太空的相機，拍到牛打出來的嗝。 Why did the scientists take pictures of cow burps from space? 為什麼要拍這種照片呢？ When cows burp, they make a gas. This gas is called methane. 因為當牛打嗝的時候，會產生一種氣體，名叫甲烷。 Too much methane makes the world hotter. So, too much methane is not good for the world. 太多甲烷會造成全球暖化。 The scientists want to find out where the methane is. They can see where the methane is in the pictures from the satellite. This can help them understand how much methane there is in the world. 科學家用人造衛星拍照，可以看出來什麼地方有很多甲烷。 What does a picture of cow burps look like? In the pictures from space, they look blue. That's right! A cow burp looks blue in a photo! 所以牛打嗝長什麼樣子呢？在照片中，這些嗝是藍色的！ What about farts? I wonder what a fart looks like? 我很好奇放屁會是什麼樣子？ ________________________________ Vocabulary 牛打嗝放屁的氣體都有甲烷，而這種氣體是全球暖化的重要原因。 1. burp 打嗝 Cows burp, and we burp too. 牛打嗝，我們也打嗝。 So we also make methane. 所以我們也製造甲烷。 We make more CO2. 我們製造比較多的二氧化碳。 It's another kind of gas. 它是另外一種氣體。 2. take picture 拍照 Would you take a picture of me? 幫我拍一張照片好嗎？ Of you eating watermelon? 拍你吃西瓜喔？ Yeah, I want to post the picture on my Facebook. 對，我要把照片po在臉書上。 3. photo 照片 What's so special about the photo? 這張照片有什麼特別？ It can cool people down. 可以讓人覺得涼快一點。 4. camera 照相機 My camera takes 4 photos in one second. 我的相機每秒拍四張照片。 That's an amazing camera! 真驚人的相機！ 你經常拍照嗎? 來讀讀單字。 burp 打嗝 take picture 照相 photo 照片 camera 相機 ________________________________ Quiz 1.
