一、高中英语阅读理解科普环保类
1．犇犇阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。
A team of international scientists is due to t off for the world's biggest iceberg in a mission aiming to answer fundamental questions about the impact of climate change in the polar regions. The scientists, led by the British Antarctic Survey (BAS), are trying to reach a newly revealed ecosystem that had been hidden for 120,000 years below the Larn C ice shelf.
Last year, part of the Larn C ice shelf calved (崩解) away, forming a huge iceberg-A68—which is four times bigger than London, and revealing life beneath for the first time. Now scientists say it is a race against time to explore the new ecosystems before they are transformed to the light. Marine biologist Dr Katrin Lin from the BAS is leading the mission.
"The calving of A68 provides us with a unique opportunity to study marine life as it responds to a huge environment change," she said. "It is important that we get there quickly before the undera environment changes as sunlight enters the water."
Professor David Vaughan, science director at the BAs, said, "We need to be bold (大胆的) on this one跳跳糖怎么玩. Larn C is a long way south and there's lots of a ice in the area, but this is important science, so we will try our best to get the team where they need to be. He said climate change had already affected the a around Antarctica and is warming some coastal waters. "Future warming may make some habitats warm. Where the habitats support unique species that are adapted to love the cold and not the warm, tho species are going to either move or die."
There is growing concern about the possible impact of climate change in the Antarctic. Earlier this month, a report revealed that melting ice sheets in Greenland and Antarctica are speeding up the already fast pace of the a level ri. The rearch, published by the National Academies of Science, Engineering and Medicine, said, "At the current rate,
the world's ocean will be, on average, at least 60cm higher by the end of the century." However, it found that the process is accelerating, and more than three quarters of the acceleration since 1993 is due to melting ice sheets in Greenland and Antarctica, the study shows.

（4）What can we infer from the last paragraph?
A. There is no need to worry about climate change in Antarctica.
B. The ice sheets in Greenland and Antarctica are melting at a steady rate.
C. Many creatures living in deep water will die out due to climate change.

【解析】【分析】本文是一篇说明文，南极地区的拉森C冰架崩解形成了一座巨大的冰山A68 iceberg。冰山下面显现的新的海洋生态系统为科学家提供了研究未知的海洋生物的机会。
（1）考查细节理解。根据第二段中的“Now scientists say it is a race against time to explore the new ecosystems before they are transformed to the light.”可知，科学家着急赶去世界最大的冰山是为了在其受到光照影响之前研究这座冰山下面的海洋生态系统。故选B。
（2）考查词义猜测。根据第三段中的“The calving of A68 provides us with a unique opportunity to study ”可知A68冰山的形成为科学家提供了研究海洋生物的独一无二的机会，所以Professor David Vaughan认为科学家要果敢地抓住这次机会，故this one指的是A68冰山和它下面的生态系统。故选C。
（3）考查细节理解。根据第一段中的“to reach a newly revealed ecosystem that had been hidden for 120,000 years below the Larn C ice shelf.”到达一个新发现的在拉森冰架下面隐藏了12万年的的生态系统，可知选D。
朴实的近义词 （4）考查推理判断。根据最后一段中的“…At the current rate, the world's oceans will be, on average, at least 60cm higher by the end of the century.”按目前的速度，世界的海洋到本世纪末平均至少升高60厘米，选D。
