二、聽力原文

During the arctic winter from October to March, the average temperature in the frozen north typically hovers around minus 20 degrees Celsius. But this year the Arctic is experiencing much higher temperatures. On February the 20th the temperature in Greenland climbed above freezing or zero degrees Celsius and it stayed there for over 24 hours. Then on February the 24th the temperature on Greenland‘s northern tip reached six degrees Celsius. Climate scientists describe the phenomenon as stunning. Weather conditions that drive this bizarre temperature surge have visited the Arctic before. They typically appear about once in a decade. However, the last such increase in temperature took place two years ago. This is troubling as climbing arctic temperatures combined with rapid sea ice loss are creating a new type of climate feedback loop which could accelerate Arctic warming. Indeed, sea ice cover in the Arctic is melting faster than expected. Without those masses of cooling sea ice, warm air brought to the Arctic can penetrate further inland than it ever did before. The air can stay warmer longer too. This drives additional melting. Overall earth is warming at a rapid pace. 2014 through 2017 rank as the hottest years on record and the Arctic is warming twice as fast as any place else on earth. This raises unique challenges for Arctic wildlife and indigenous people who depend on Arctic ecosystems to survive. Previously climate forecasts predicted that Arctic summer ice would disappear entirely by around 2060, but based on what scientists are seeing now the Arctic may be facing summers without ice within 20 years.
Question 9: What did climate scientists describe as stunning?
Question 10: What does the passage say about that temperature surge in the Arctic?
Question 11: What may occur in 20 years according to scientists’ recent observations?

【翻譯】

在10月至3月，北極的冬季，冰凍的北方平均氣溫通常在零下20攝氏度左右。

但今年，北極地區(qū)的氣溫要高得多。

2月20日，格陵蘭島的氣溫攀升至零度以上，并持續(xù)了24個多小時。

2月24日，格陵蘭島北端的溫度達(dá)到了6攝氏度。氣候科學(xué)家稱這一現(xiàn)象“令人震驚”。

導(dǎo)致這種奇怪的氣溫飆升的天氣條件以前也曾出現(xiàn)在北極地區(qū)。它們通常每十年出現(xiàn)一次。

然而，最近一次氣溫上升發(fā)生在兩年前。

這令人擔(dān)憂，因為北極氣溫不斷攀升，加上海冰迅速減少，正在形成一種新型的氣候反饋回路，可能加速北極變暖。

事實上，北極海冰的融化速度比預(yù)期的要快。

沒有這些大量的冰冷的海冰，帶到北極的暖空氣可以以前所未有的程度都深入內(nèi)陸。

空氣變暖也還會持續(xù)更長時間。這會導(dǎo)致進(jìn)一步的融化。

總的來說，地球正在快速變暖——2014年到2017年是有記錄以來最熱的年份，北極的變暖速度是地球上其他地方的兩倍。

這對依賴北極生態(tài)系統(tǒng)生存的北極野生動物和土著居民提出了獨特的挑戰(zhàn)。

此前，氣候預(yù)報預(yù)測，北極夏季冰層將在2060年左右完全消失。

但根據(jù)科學(xué)家目前的觀察，北極可能在20年內(nèi)面臨沒有冰的夏季。

請根據(jù)你剛剛聽到的短文回答第9題至第11題。

9. 氣候科學(xué)家認(rèn)為什么是“驚人的”？

10. 這篇文章對北極的氣溫飆升有什么看法？

11. 根據(jù)科學(xué)家最近的觀察，20年后可能會發(fā)生什么？
