Earth’s Hot, Dry Twin

Earth’s Hot, Dry Twin  Four and a half billion years ago, Venus and Earth were born together. They looked almost the same. They both had blue oceans and green mountains. They were twin planets! 45億年前，金星跟地球一起誕生。兩個星球看起來幾乎一樣，都有藍色的大海和綠色的山，簡直是雙胞胎! Earth is the right distance from the sun. Earth's oceans are full of water. Earth is warm but not too hot. The air is cool. 地球的海洋充滿水分，又離太陽的距離很剛好，讓地球很溫暖又不會太熱，空氣也很涼爽。 But Venus is too close to the sun.* *The sun’s heat made Venus’ oceans lose water. 但是金星離太陽太近了，金星的海洋都蒸發了。 Venus has a lot of volcanoes. Lots of bad gases came out of them. The gases made the air thick. The thick air kept more heat in. Venus became the hottest planet around the sun! 金星又有很多火山釋放大量的氣體，讓大氣層變得很厚，整個星球又更熱，成為太陽周圍最熱的行星! Water is made from hydrogen and oxygen. In the thick air around Venus, hydrogen and oxygen are cut apart. Hydrogen goes into space. With no hydrogen, Venus cannot have more water. Now it’s Earth’s hot, dry twin. 水是由氫氣跟氧氣組成。金星的大氣層讓氫氣釋放到太空中。沒有氫氣，金星就沒有水，就變成現在地球又熱又乾的雙胞胎。 Scientists study Venus to learn how to protect the air and oceans on Earth. The story of Venus and Earth teaches us to care for our planet. ---------------------------------------------------------------------------------------------------------------- Vocabulary 金星誕生的時候跟地球很像，後來的命運卻大不相同。 1. blue 藍色、green 綠色 Look at the photos from the Space Station.你看從太空站拍的照片。 All those blue oceans and green forests. 藍海跟綠色森林。 Yeah, so pretty! 對啊，真美! 2. hottest 最熱的 But it’s getting hotter, don’t you think? 但是越來越熱，你不覺得嗎?
