Passage one.
短文一
While some scientists explore the surface of Antarctica, others are learning more about a giant body of water four kilometres beneath the ice pack.
當一些科學家探索南極洲的表面時，另一些科學家正在對冰蓋下4公里處的巨大水體進行更多的了解。
Scientists first discovered Lake Vostok in the 1970s by using radio waves that penetrate the ice.
20世紀70年代，科學家們通過穿透冰層的無線電波首次發現了沃斯托克湖。
Since then, they have used sound waves and even satellites to map this massive body of water.
從那時起，他們就一直在利用聲波甚至衛星來繪制這片巨大的水域。
How does the water in Lake Vostok remain liquid beneath an ice sheet?
沃斯托克湖的水在冰原下是如何保持液態的?
“The thick glacier above acts like insulating blanket and keeps the water from freezing,” said Martin Siegert, a glaciologist from the University of Wales.
威爾士大學的冰川學家馬丁·斯哥特說：“上面厚厚的冰川就像保溫層，可以防止水結冰。”
In addition, geothermal heat from deep within the earth may warm the hidden lake.
此外，來自地球深處的地熱也可能會讓這個隱藏的湖變暖。
The scientists suspect that microorganisms may be living in Lake Vostok closed off from the outside world for more than 2 million years.
科學家們懷疑微生物可能生活在與外界隔絕了200多萬年的沃斯托克湖中。
"Anything found there will be totally alien to what's on the surface of the earth", said Siegert.
“在那里發現的任何東西都將與地球表面的東西完全不同”，斯哥特說。
Scientists are trying to find a way to drill into the ice and draw water samples without causing contamination.
科學家正試圖尋找一種方法，在不造成污染的情況下，在冰中鉆取水樣。
Again, robots might be the solution. If all goes as planned, a drill-shaped robot will through the surface ice.
又一次，解決方法可能是機器人。如果一切按計劃進行，一個鉆形機器人將穿過表面冰層。
When it reaches the lake, it will release another robot that can swim in the lake, take pictures, and look for signs of life.
當它到達湖里時，會釋放另一個機器人，這個機器人可以在湖里游泳、拍照，尋找生命的跡象。
The scientists hope their discoveries will shed light on life in outer space, which might exist in similar dark and airless conditions.
科學家們希望他們的發現將為外太空的生命提供線索，外太空的生命可能也存在于類似的黑暗和無空氣環境中。
Recently, close up pictures of Jupiter's moon Europa shows signs of water beneath its icy surface.
最近，木星的衛星木衛二的特寫照片顯示，在其冰冷的表面下有水的跡象。
Once tested in Antarctica, robots could be sent to Europa to search for life there too.
一旦在南極洲通過測試，機器人就可以被送往木衛二去尋找那里的生命。
