The discovery of Greenland’s icy Grand Canyon is quite surprising. How could something so large exist, and we only just recently noticed it? The canyon also helps scientists understand the environmental history of Greenland. Even though we would like to see the canyon up close, we don’t want all the ice covering it to melt. If it did, the world’s sea level would go up seven meters, which would do more harm than good.
發現格陵蘭冰雪大峽谷是一件相當令人驚訝的事。這麼巨大的東西怎麼可能存在，而我們最近才注意到它？峽谷也幫助了科學家了解格陵蘭的環境史。儘管我們想近距離地觀察峽谷，但我們可不希望所有覆蓋它的冰都融化。如果真是這樣，世界的海平面將上升七公尺，這將弊大於利。
生活必備字詞：
exist vi. 存在
environmental a. 環境的
do more harm than good 壞處多於好處，弊多於利
