题目内容
10.If you want to see climate change,head north and keep going until you run out of globe.That is easier said than done.The Arctic (北极) is home to few people and covered in ice much of the year.But those who make their way to the icy seas of the Arctic Ocean will see a part of the planet that is warming and changing faster than anywhere else.In September,scientists announced at the National Snow and Ice Data (数据) Center that Arctic summer sea ice had fallen to its second lowest level since 1979,and probably long before that.The Arctic has lost an area of ice greater than the area of all U.S.states east of the Mississippi River.And what ice remains appears to be getting thinner and weaker.
Nick Toberg and Till Wagner are polar ice scientists who are doing sea ice fieldwork."There is plenty of data to suggest that the ice is becoming thinner as well as smaller in area,"they say.
The changes happening in the Arctic are a warning for the entire world.As polar expert Walt
Meier puts it,"What happens in the Arctic doesn't stay in the Arctic."
Some scientists worry that Arctic sea ice may be going from a downward spiral (螺旋线) to a"death spiral",one from which there is no escape.As more ice melts (融化),more dark open water appears.The darkness absorbs (吸收) more heat,which speeds up the pace of melting.
Until recently,many scientists thought it might take until the end of the century for the North Pole to become completely ice free during the summer.Now some believe it could happen by 2030or even earlier."The melting is happening faster in the real world than it has in the models,"says Nick Toberg.

A.it's difficult to arrive at the Arctic
B.it is too cold for people to live in the Arctic
C.what caused the climate change in the Arctic
D.we can see the most obvious climate change in the Arctic
60.From the second paragraph we can learn Arctic summer sea iceA.
A.is still decreasing
B.began reducing in 1979
C.fell to its lowest level in September
D.is equal to the Mississippi River
61.What does the underlined sentence in Paragraph 3mean?D
A.The changes don't affect the Arctic at all.
B.The changes will only happen in the Arctic.
C.The changes happening in the Arctic will stop.
D.The changes will also affect other parts of the world.
62.Nick Toberg may agree thatB.
A.the ice in the North Pole will stop melting
B.the ice in the North Pole is melting faster than expected
C.the ice in the North Pole will melt before 2030or even earlier
D.the ice in the North Pole will not disappear until the end of the century.
分析 文章大意:本文讲的是北极的冰层变得越来越薄,科学家Nick Toberg指出北极冰层的融化会比我们想象的要快,会给整个世界带来危害.
解答 59.D 目的意图题.根据文章第一段第一句话If you want to see climate change,head north and keep going until you run out of globe和最后一句话But those who make their way to the icy seas of the Arctic Ocean will see a part of the planet that is warming and changing faster than anywhere else可知作者是要告诉读者在北极能够看到气候的变化要比任何其他地方都要快,因此答案选D.
60.A 细节理解题.根据文章第二段最后一句话Nick Toberg and Till Wagner are polar ice scientists who are doing sea ice fieldwork."There is plenty of data to suggest that the ice is becoming thinner as well as smaller in area,"they say可知北极的海冰还在减少,因此答案选A.
61.D 推理判断题.根据文章第三段第一句话The changes happening in the Arctic are a warning for the entire world可知北极气候的变化会给世界其他地方带来警告,影响世界其他地方,因此答案选D.
62.B 细节理解题.根据文章最后一段最后一句话."The melting is happening faster in the real world than it has in the models,"says Nick Toberg可知Nick Toberg认为北极冰层的融化速度要比预期的快,因此答案选B.
