據科學傢稱，有城市般大小、寬度可能達到數十公裡的冰山曾漂浮在英國近海。研究人員發現瞭這些漂流的冰山留下的獨特刮痕。
Scientists found the deep tracks left by these icebergs by looking at energy companies’ seismic surveys of the North Sea. It showed icebergs the size of Norwich were once found off the eastern coast of Scotland. This is the first hard evidence that the ice sheet that covered Britain and Ireland 18,000 years ago produced such large icebergs.
科學傢們通過分析能源公司對北海的地震勘測資料發現瞭冰山留下的深深的軌跡。資料表明與諾裡奇市大小相當的冰山曾出現在蘇格蘭的東海岸。這是首個確鑿證據證明 1.8 萬年前覆蓋著不列顛和愛爾蘭的冰蓋曾行成過如此巨大的冰山。
The findings may help scientists answer fundamental questions about how the Antarctic ice sheet may be affected as the ice shelves around its edge become unstable in a warming world.
這些發現或許能幫助科學傢們解答關於南極冰蓋的一些關鍵問題：隨著全球變暖，南極冰蓋邊緣的冰架變得愈發不穩定，南極冰蓋將受到怎樣的影響。

答案
一、聽第一遍音頻，回答問題。
1. What is the main topic of this report?
The report is about new evidence that icebergs the size of Norwich were once found off the eastern coast of Scotland.
二、用一分鐘閱讀下列問題，然後聽第二遍音頻並回答問題。
1. a. Scientists found the deep tracks left by these icebergs by looking at energy company’s seismic surveys of the North Sea.
2. c. It showed icebergs the size of Norwich were once found off the eastern coast of Scotland.
3. b. False. This is the first hard evidence that the ice sheet that covered Britain and Ireland 18,000 years ago produced such large icebergs. Here, ‘the’ means scientists already knew there was an ice sheet that covered Britain and Ireland 18,000 years ago.
4. a. True. The findings may help scientists answer fundamental questions about how the Antarctic ice sheet may be affected…
