【正确答案】
B
【答案解析】[听力原文] Research into the icecap of North Pole has found that it is melting so quickly that the Arctic Ocean could lose most of its ice during summer time in as little as ten years. Scientists of Cambridge University say recent exploration to the Arctic led by explorer Pen Hadow found ice was much thinner than expected and less dense, subject to rapid melting. Mr. Hadow said the finding should act as a wake-up call. The long-term view for the global community, this is definitely not good news. But if we can see this for what it is which is the biggest visual cue that we are going to get to manage our relationship with the planet better, then that is a good thing. What is this news item mainly about? 主旨大意题。新闻中报道：北极积冰的融化速度太快(it is melting so quickly)导致北冰洋冰雪将在10个夏天之后基本融掉。剑桥大学的科学家们说最近的北极探险发现冰块比想象中的更薄、更稀了。可见新闻主要是说北极冰雪的快速融化。B项中的The increased melting是对原文的同义改写，故答案是B项。A项“建设地球村的建议”在新闻中没有提到。虽然剑桥大学的科学家们说最近的北极探险发现冰块比想象中的更薄了，但这是为了引出北极积冰融化加快这一主题，C项“探险队员到北极探险”和D项“剑桥大学的科学研究”都不是新闻的主要内容。
