Polar bears live in such an environment that is too cold for most animals. For much of the year, they live and hunt on the 1. (freeze) Arctic sea ice. Nature has prepared them for the cold conditions but nothing has prepared them for the danger that 2. (threaten) their only home.

The polar bears’ world is melting. Polar bears 3. (suffer) in a warmer world are in danger. Studies show that the polar ice 4. (reduce) by 9.8% every 10 years since 1978.At present, about 20,000 to 25,000 polar bears live in the Arctic. Polar bears depend on the sea ice for their 5. (survive). “The sea ice is more than just the platform that the bears walk 6. ,” says Andrew Derocher, who studies North American polar bear populations. “Without 7. , they can’t exist.”

答案及剖析:

1.frozen 考查形容词。这里用形容词修饰名词, frozen 冰冻的。

2.threatens 考查主谓一致。分析句子结构可知,that引导定语从句,修饰先行词the danger,that在定语从句中作主语,所以后面的谓语动词用单数形式。

3.suffering 考查非谓语动词。 in a warmer world是非谓语动词短语作后置定语修饰Polar bears,Polar bears是suffer的逻辑主语,两者之间是主动关系,所以用动词-ing形式。

4.has reduced 考查动词时态。since 1978提示是现在完成时,主语the polar ice和reduce 之间是主谓关系,且表示主动,所以是has reduced。

5.survival 考查名词。用名词作介词for的宾语,所以用名词形式survival。
