2018.12六级第一套 Passage One

During the arctic winter from October to March, the average temperature in the frozen north typically hovers around minus 20 degrees Celsius.

在10月至次年3月的北极冬季，冰冻北部的平均温度通常在零下20摄氏度左右徘徊。

But this year the Arctic is experiencing much higher temperatures.

但是今年北极正在经历更高的温度。

On February the 20th the temperature in Greenland climbed above freezing or zero degrees Celsius and it stayed there for over 24 hours.

2月20日，格陵兰岛的气温升至零摄氏度以上，并保持超过24个小时。

Then on February the 24th the temperature on Greenland's northern tip reached six degrees Celsius.

然后在2月24日，格陵兰岛北端的温度达到了6摄氏度。

Climate scientists describe the phenomenon as stunning. Weather conditions that drive this bizarre temperature surge have visited the Arctic before.

气候科学家称这种现象令人震惊。导致气温反常飙升的情况过去也曾在北极发生过。

They typically appear about once in a decade. However, the last such increase in temperature took place two years ago.

它们通常每十年发生一次。然而，上一次这样的温度升高是两年前才发生的。

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.

这令人不安，因为不断升高的北极温度加上快速的海冰损失，正在创造一种新型的气候反馈循环，而它可以加速北极变暖。

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.

实际上，北极的海冰盖融化速度比预期的要快。如果没有大量海冰的冷却，被带到北极的暖空气可以比以前更深入地渗透到内陆。

The air can stay warmer longer too. This drives additional melting.

空气也可以保持更长时间的温暖。这会带来更多的融化。

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.

整个地球正在快速变暖。2014年至2017年是有记录以来最热的年份，而北极的变暖速度是地球上任何其他地方的两倍。

This raises unique challenges for Arctic wildlife and indigenous people who depend on Arctic ecosystems to survive.

这给依赖北极生态系统生存的北极野生动物和土著居民带来了特殊的挑战。

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.

先前的气候预测估计，北极夏季冰将在2060年左右完全消失，但根据科学家现在所看到的情况，北极可能在20年内就会面临无冰的夏季。

问题：

9: What did climate scientists describe as stunning?

A) The unprecedented high temperature in Greenland.

B) The collapse of ice on the northern tip of Greenland.

C) The unusual cold spell in the Arctic area in October.

D) The rapid change of Arctic temperature within a day.

10: What does the passage say about that temperature surge in the Arctic?

A) It has created a totally new climate pattern.

B) It will pose a serious threat to many species.

C) It typically appears about once every ten years.

D) It has puzzled the climate scientists for decades.

11: What may occur in 20 years according to scientists' recent observations?

A) Extinction of Arctic wildlife.

B) Iceless summers in the Arctic.

C) Emigration of indigenous people.

D) Better understanding of ecosystems.
