Question

A victim of climate change

         A polar bear's dead body found on the Arctic island of Svalbard, the northernmost part of Norway, has shocked experts who say climate change may be to blame for the death. The starved polar bear in Norway was said to be in good bones by the time a group of explorers came across its body in July．

The bear is thought to have been heading north in a desperate search for sea ice that would allow it to hunt for seals．"From his lying position in death, the bear appears to simply have starved to health in April when the Norwegian Polar Institute examined and labeled it． However, the animal was reduced to skin and bones and died where he dropped," polar bear expert Dr. Ian Stirling, a professor at the University of Alberta said, "He had external suggestion of any remaining fat, having been reduced to little more than skin and bone．"

Stirling believes the bear starved to death as a result of a lack of sea ice which the animals use as a platform for hunting seals． That may also explain why the 16-year-old male bear was found about 155 miles north of where it was seen in April．

Arctic sea ice reached a record low in 2012, according to a report released this week by the National Oceanic and Atmospheric Administration that pointed to continued signs of climate change．

The International Union for Conservation of Nature currently classifies polar bears as vulnerable on its Red List of Threatened Species．

1.How did Stirling know the reason for the death of the polar bear?

A．By the food he ate．                         B．By doing further experiments．

C．By observing other polar bears．              D．By his lying position in death．

2.The underlined word "vulnerable" probably means _____．

A．easily hurt                        B．difficult to hunt

C．dangerous                        D．a(chǎn)mazing

3.What is the author's attitude to the incident?

A．Favorable．           B．Uncaring．         

C．Doubtful．             D．Concerned．

4.Where does this text probably come from?

A．A novel．                       B． A guidebook．      

C．A news report．                  D．An advertisement．

【解析】

試題分析：文章講述了在挪威北部北極的一個島上發(fā)現(xiàn)了一頭北極熊，這件事使專家很震驚。從發(fā)現(xiàn)北極熊的地方看，是北極熊為了尋找食物在向北去的路上死掉的，他是為了尋找冰來作為他獵取海豹的平臺才向北轉(zhuǎn)移的，在些過程中因饑餓而死。這一事件是由氣候的變化引起的，因?yàn)槿�球的氣候變暖，使冰在減少，才使北極熊處于瀕危境地。

1. D細(xì)節(jié)理解題。.. From his lying position in death, the bear appears to simply have starved to health in April when the Norwegian Polar Institute examined and labeled it。句意為：當(dāng)挪威極地研究院在檢測北極熊時發(fā)現(xiàn)，從他死的位置上可以看出，北極熊是在四月份因饑餓而死的。故答案為D。

2.A詞義理解題。The International Union for Conservation of Nature currently classifies polar bears as vulnerable on its Red List of Threatened Species．國際聯(lián)盟自然保護(hù)機(jī)構(gòu)將北極熊歸類到了瀕危物種的紅色名單上。由此可知北極熊是易受攻擊，受傷害的動物。dangerous 危險(xiǎn)的，此處并非北極熊是危險(xiǎn)的，而是處于危險(xiǎn)之中。故答案為A。

3.D綜合理解題。文中從發(fā)現(xiàn)北極熊開始到對動物檢測，查找原因，對這件事情一直處在關(guān)注之中，同時也了解到，挪威自然研究院把北極熊劃為瀕危動物的行列。故作者對此事是關(guān)注的，所以答案應(yīng)為D。

4.C段落理解題。文章從發(fā)現(xiàn)北極熊的尸體開始展開，經(jīng)過對熊尸體的檢測，推測出了是因氣候變化而導(dǎo)致死亡的原因，同時指出了氣候變暖使北極的冰在連年減少，2012年達(dá)到了新的紀(jì)錄。所以這篇文章應(yīng)出自于一篇報(bào)道。novel 小說,文章并非在講一個故事；a guidebook 一本指導(dǎo)書，文章并未對事情作出指導(dǎo)；advertisement 廣告，沒有介紹什么產(chǎn)品，故答案應(yīng)為C。
