这是一道信息还原题,主要考查学生对英语短文的理解能力和对上下文逻辑关系的把握能力。题目给出了一个关于阿拉斯加气候变化的短文,其中留有5个空格需要从方框中选出最佳选项填入。这类题目需要学生先通读全文,理解短文的大意和结构,然后再逐句分析空格前后文的逻辑关系,最后从选项中找出最符合语境和逻辑的句子。
1. 第一个空格,根据前文"Over the past 60 years, Alaska has been about 3 degrees warmer."以及后文"This changes ecosystems."可以推断出,此处需要填入一个描述阿拉斯加气候变化程度的句子,与后文形成因果关系。选项E"That is more than twice as much as the rest of the United States."符合语境,表示阿拉斯加的气候变化程度是其他地区的两倍多。
2. 第二个空格,根据前文"Permafrost usually stays frozen all year."以及后文"Some part of it is melting, though."可以推断出,此处需要填入一个描述阿拉斯加永久冻土分布情况的句子,为后文描述冻土融化做铺垫。选项B"Most of Alaska has permafrost."符合语境。
3. 第三个空格,根据前文"As it melts, it gets softer. The ground above can fall down."可以推断出,此处需要填入一个描述冻土融化对上层地面影响的句子。选项D"This can cause damage to whatever is built on top of it."符合语境,表示冻土融化会对上层建筑造成损害。
4. 第四个空格,根据前文"Some get bigger."以及后文"Millions of birds travel to these lakes when it's warm."可以推断出,此处需要填入一个描述湖泊变化的句子,与前文形成对比关系。选项A"Others get smaller."符合语境,表示有些湖泊变大了,有些则变小了。
5. 第五个空格,根据前文"Warmer, drier weather makes wildfires more frequent."以及后文"Fires change the forest."可以推断出,此处需要填入一个描述野火对森林影响的句子。选项F"Large wildfires have destroyed more forests in Alaska than ever before."符合语境,表示野火摧毁了比以往更多的森林。

To protect air, soil and water, we can take several actions. First, we should plant more trees to keep the air clean. Second, we must stop throwing rubbish into the soil and water. Third, we can use public transport instead of cars to reduce air pollution. Fourth, we should save water by turning off the tap when not in use. Finally, we can tell others about the importance of protecting these non-living things.
