18.In face of global warming,much effort has been focused on reducing greenhouse gas emissions through a variety of strategies.But while much of the research and innovation has concentrated on finding less-polluting energy alternatives,it may be decades before clean technologies like wind and solar meet a significant portion of our energy needs.In the meantime,the amount of CO2 in the air is rapidly approaching the limits proposed by the Intergovernmental Panel on Climate Change (IPCC)."As long as we're consuming fossil fuels,we're putting out CO2,"says Klaus Lackner,a geophysicist at Columbia University,"We cannot let the CO2 in the atmosphere rise indefinitely."
That sense of urgency has increased interest in capturing and storing CO2,which the IPCC says could provide the more than 50% reduction in emissions needed to reduce global warming."We see the potential for capture and storage to play an integral (基本的) role in reducing emissions,"says Kim Corley,Shell's senior advisor of CO2 and environmental affairs.That forward thinking strategy is gaining support.The U.S.Department of Energy recently proposed putting 1billionintoanew2.4billion coal-burning energy plant.The plant's carbon-capture technologies would serve as a pilot project for other new coal-burning plants.
But what do you do with the gas once you've captured it?One option is to put it to new uses.Dakota Gasification of North Dakota captures CO2 at a plant that converts (转换) coal into synthetic(合成的)natural gas.It then ships the gas 200miles by pipeline to Canada,where it is pumped underground in oil recovery operations.In the Netherlands,Shell delivers CO2 to farmers who pipe it into their greenhouses,increasing their production of fruits and vegetables.
However,scientists say that the scale of CO2 emissions will require vast amounts of long-term storage.Some propose storing the CO2 in coal mines or liquid storage in the ocean,Shell favors storing CO2 in deep geological structures such as saline (盐的) formations and exhausted oil and gas fields that exist throughout the world.
67.What does the author intend to tell readers?C
A.How to find more oil and natural gases.B.How to reduce greenhouse gas emissions.
C.How to deal with the greenhouse gas creatively.
D.How to make good use of solar and wind energy.
68.According to the passage,the following statements are true EXCEPT thatB.
A.the idea of capturing and storing CO2 is supported by the American government
B.it is widely accepted that the CO2 captured should be stored in deep geological structures
C.capturing and storing CO2 is intended to handle the problem with global warming
D.long-term storage of CO2 is no easy job because of the scale of CO2emissions
69.By using CO2,Dutch farmers have been able toA.
A.increase their production of fruits and vegetables B.convert coal into synthetic natural gas
C.pump it underground in oil recovery operations D.make exhausted oil and gas fields productive
70.How would you understand the underlined part in the third paragraph?C
A.It means a project training new pilots who will serve the new strategy.
B.It refers to the coal-burning energy plant that U.S government sponsors.
C.It implies the carbon-capture technologies will be popular once successful.
D.It shows the new idea of reduction of CO2 emissions needs a large sum of investment.
分析 本文是一篇科教类阅读,属于说明文,面对全球变暖,很多努力都集中在通过各种策略减少温室气体排放.不过,虽然很多研究和创新都集中在寻找较环保的替代能源,这可能是几十年的清洁能源技术,如风力和太阳能满足我们的能源需求显著部分之前.本文以此展开,主要讲述了如何处理温室气体.
解答 67.C.主旨大意题.根据第一段中"much effort has been focused on reducing greenhouse gas emissions through a variety of strategies"可知本文主要讲述如何处理温室气体,故答案为C项.
68.B.细节理解题.由最后一段"Some propose storing the CO2 in coal mines or liquid storage in the ocean,Shell favors storing CO2 in deep geological structures such as saline (盐的) formations and exhausted oil and gas fields that exist throughout the world."可知这种观点并不是被广泛接受的,故答案为B项.
69.A.细节理解题.根据第四段最后一句"Netherlands,Shell delivers CO2 to farmers who pipe it into their greenhouses,increasing their production of fruits and vegetables."可知,通过使用二氧化碳,荷兰农民能够增加水果和蔬菜的产量.故答案为A项.
70.C.句意理解题.本句意为这项技术获得成功的话,对于其他一些工厂将会是一个试点工程,如成功的话,其他工厂肯定会效仿.故答案为C项
点评 本文是一篇科教类阅读,题目涉及多道细节理解题,句意理解题,主旨大意题.做题时学生应仔细阅读原文,把握文章主要内容,联系文章上下文内容并结合所给选项含义,从中选出正确答案,一定要做到有理有据,切忌胡乱猜测.
