Within a large concrete room, cut out of a mountain on a freezing-cold island
just 1,000 kilometers from the North Pole, could lie the future of humanity.
The room is a vault(地下库) designed to hold around 2 million seeds, representing all known
varieties of the world’s crops. It is being built to safeguard the word’s food supply against
nuclear war, climate change, terrorism, rising sea levels, earthquakes and the collapse of electricity
supplies “if the worst came to the worst, this would allow the world to reconstruct agriculture on
this planet,” says Cary Fowler, director of the global Crop Diversity Trust ,an independent
international organization promoting the project .
The Norwegian (挪威的)government is planning to create the seed bank next year at the request
of crop scientists. The $3 million vault will be built deep inside a sandstone mountain on the
Norwegian Arctic island of Spitsbergen. The vault will have metre-thick walls of reinforced concrete
and will be protected behind two airlocks and high-security doors.
The vault’s seed collection will represent the products of some 10,000 years of plant breeding
by the world’s farmers, though most are no longer widely planted, the varieties contain vital genetic
properties still regularly used in plant breeding .
To survive, the seeds need freezing temperatures. Operators plan to replace the air inside the
vault each winter, when temperatures in Spitsbergen are around -18 °C. But even if some disaster
meant that the vault was abandoned, the permanently frozen soil would keep the seeds alive. And
ever accelerated global warming would take many decades to penetrate the mountain vault.
“This will be the world’s most secure gene bank.,” says Fowler. “But its seeds will only
be used when all other samples have gone for some reason."
The project comes at a time when there is growing concern about the safety of existing seed
banks around the world .Many have been criticized for their poor security, ageing refrigeration(冷藏)
systems and vulnerable electricity supplies.
The scheme won UN approval at a meeting of the Food and Agriculture Organization in Rome in
October 2005. A feasibility study sail the facility "would essentially be built last forever."

答案解析:
1 【答案】 B
【考点】事实细节题
【题意】挪威的这个地下库很重要因为______。
A. 库里的种子代表了世界上最稀有的庄稼的品种
B. 如果最坏的事情发生时,库里的种子可以使农业复活.
C. 它建在冰冷的北极岛的一个深山里。
D.它很坚固,可以抵御人类和自然引起的所有的灾难。
【解析】原文提到if the worst came to the worst, this would allow the world to reconstruct agriculture on this planet,可以看出正确答案应该选B。
2. 【答案】 D
【考点】事实细节题
【题意】这个种子库工程是由_____提出的。
A.挪威ZF B. 挪威的农民 B. 斯匹次卑尔根岛的居民 D. 农业科学家
【解析】原文提到The Norwegian (挪威的)government is planning to create the seed bank next year at the request of crop scientists. At the request of sb: 在某人的要求下,可以看出正确答案应该选D。
3. 【答案】 C
【考点】事实细节题
【题意】库里的种子可以储存________。
A. 作为世界庄稼品种 B. 作为世界作物育种产品
C. 为了他们的的有价值的基因特性 D. 为了他们可以预防植物疾病
【解析】原文提到the varieties contain vital genetic properties still regularly used in plant breeding. 可以看出正确答案应该选C。
4 【答案】 C
【考点】事实细节题
【题意】为了让种子库工程获得成功,最重要的因素可能是_____。
A. 建立密封的气锁 B. 保持非常高的安全性
C. 保持零点的温度 D. 储存大量的种子seeds
【解析】原文提到To survive, the seeds need freezing temperatures. 可以看出正确答案应该选C。
5. 【答案】 C
【考点】推理判断题
【题意】下面哪一项是对的?
A. 挪威的种子库是按照现存的种子库建立的。
B. 预计斯匹次卑尔根岛的种子库有10,000年的寿命。
C. 现存的种子库有很多潜在的问题。
D. 联合国资助了斯匹次卑尔根岛的种子库。
【解析】对错判断推理题的做题方法就是把四个选项和原文一一对应,逐一排除。原文倒数第二段提到The project comes at a time when there is growing concern about the safety of existing seed banks around the world .Many have been criticized for their poor security, ageing refrigeration(冷藏)systems and vulnerable electricity supplies. 可以看出现存的种子库有很多潜在的问题,故正确答案应该选择C。
