举例

Directions: Choose the one that fits best according to the information given in the passage you have just read.  

    A tiny clue found in ancient deposits has unlocked big secrets about Greenland's past and future climate. Just beyond the northwest edge of the vast Greenland Ice Sheet, researchers have discovered lake mud that have survived the last ice age. The mud, and remains of common flies in it, record two interglacial periods(间冰期)in northwest Greenland.

    Although researchers have long known these two periods—the early Holocene and Last Interglacial—experienced warming in the Arctic, the mix of fly species shows that Greenland was even warmer than previously thought. "As far as we know, it has never been found in Greenland. We think this is the first time anyone has reported it in ancient deposits or modern lakes there," Axford said. "We were really surprised to see how far north it migrated (迁徙)."

    This new information could help researchers better measure Greenland's sensitivity to warming, by testing and improving models of climate and ice sheet behaviour. Those models could then improve predictions of how Greenland's ice sheet might respond to man-made global warming. After all, Greenland covers 80 per cent of the Arctic country and holds enough ice to equal 20 feet of global sea level. "Northwest Greenland might feel really remote, but what happens to that ice sheet is going to matter to everyone in every coastal city around the world," said Yarrow Axford, an associate professor in the team. "One of the big uncertainties in climate science is how fast the Earth changes when it gets warmer. Geology gives us an opportunity to see what happened when the Earth was warmer than today," said Axford.

    People might be surprised to see how today's Greenland looked during the last two interglacial periods. During the Last Interglacial, global sea levels increased by 15 to 30 feet, largely due to thinning of Greenland and Antarctica's ice sheets. However, now researchers believe northern Greenland's ice sheet experienced stronger warming than previously thought, which could mean that Greenland is more responsible for that sea-level rise.

    Finding lake deposits older than about 10,000 years, however, has been historically very difficult in Greenland. To measure these ancient temperatures, researchers look to ice cores (冰核) and lake deposits. Since ice and lake deposits form by a gradual buildup on annual layers of snow or mud, these cores contain history of the past. By looking through the layers, researchers can obtain climate clues from centuries ago.

（1）Why are the remains of flies mentioned in the first two paragraphs?            

A.They serve as evidence that there is still life in the Northwest Greenland.

B.They were one of the many ancient lives that were left in the Greenland mud.

C.They are indicators that Greenland was much warmer than previously thought.

D.They help the researchers realize that there was once a warm period in the Arctic.

（2）The new information about Greenland is important because              .            

A.researchers have no idea how to measure Greenland's warming speed

B.it can help researchers better predict Greenland's response to warming

C.people should be more sensitive to the changes in the ice in Greenland

D.it is uncertain how fast the Earth changes with man-made global warming

（3）Which of the following can be inferred from the passage?            

A.It is easier for today's scientists to find ancient lake deposits.

B.People are surprised at the landscape feature of Greenland today.

C.Researchers measure the changing temperatures by directly examining mud.

D.Greenland holds enough ice that might one day threaten life in coastal cities.

（4）Which do you think is the best title of the passage?            

A.Greenland Used to Be Much Greener

B.Earth Once Experienced Warm Periods

C.Coastal Cities Warned of Coming Disasters

D.Northwest Greenland, A Perfect Destination

【答案】 

（1）C

（2）B

（3）D

（4）A   

【解析】【分析】本文是一篇说明文，介绍了在古代沉积物中发现的一条微小线索揭开了格陵兰岛过去和未来气候的大秘密。就在广阔的格陵兰冰原的西北边缘，研究人员发现了在最后一个冰河时代幸存下来的湖泥。现在研究人员认为，格陵兰北部的冰盖经历了比之前认为的更强烈的变暖。

 （1）考查推理判断。根据第一段中的“The mud, and remains of common flies in it, record two interglacial periods（间冰期）in northwest Greenland.”在格陵兰岛西北部，泥浆和常见苍蝇的残骸记录了两次间冰期；以及第二段中的“Although researchers have long known these two periods—the early Holocene and Last Interglacial—experienced warming in the Arctic, the mix of fly species shows that Greenland was even warmer than previously thought. ”尽管研究人员很早就知道这两个时期——全新世早期和最后一次间冰期——在北极经历了变暖，但混合的蝇类表明格陵兰岛甚至比之前认为的还要热。可知，在前两段中提到苍蝇的残骸是为了证明格陵兰岛的温度比之前认为的要高得多。故选C。

 （2）考查细节理解。根据第三段中的“This new information could help researchers better measure Greenland's sensitivity to warming, by testing and improving models of climate and ice sheet behaviour. ”可知，这些新信息可以帮助研究人员更好地测量格陵兰岛对气候变暖的敏感性。故选B。

 （3）考查细节理解。根据第三段中的“After all, Greenland covers 80 per cent of the Arctic country and holds enough ice to equal 20 feet of global sea level. ‘Northwest Greenland might feel really remote, but what happens to that ice sheet is going to matter to everyone in every coastal city around the world,’”  可知，格陵兰岛覆盖了这个北极国家的80%，拥有相当于全球海平面20英尺的冰。“格陵兰西北部可能真的感觉很遥远，但冰盖的变化将关系到世界上每个沿海城市的每个人。”故选D。

 （4）考查主旨大意。本文通过最新的发现——最后一个冰河时代幸存下来的湖泥及湖泥中的苍蝇残骸及其相关研究说明格陵兰岛之前可能更暖和。因此，本文的最佳标题应为“格陵兰岛曾经更加绿色”。故选A。

 【点评】本题考点涉及细节理解，推理判断和主旨大意三个题型的考查，是一篇科研类阅读，考生需要准确捕捉细节信息，并根据上下文进行逻辑推理，概括归纳，从而选出正确答案。
