题目内容
3."Ten years ago I could never have imagined I'd be doing this,"says Greg Pal,33,a former software executive."I mean,this is essentially agriculture,right?But the people I talk to,especially the ones coming out of business school,think this is the one hot area everyone wants to get into."He means bugs.To be more accurate,the genetic(基因的) change of bugs---very,very small ones---so that when they feed on agricultural waste such as woodchip or wheat straw,they do something extraordinary.They excrete (排泄) crude oil.
Unbelievably,this is not science fiction.Mr.Pal holds up a small cup of bug excretion that could,in theory,be poured into the tank of the big Lexus SUX next to us.Not that Mr.Pal was willing to risk it just yet.He gives it a month before the first vehicle is filled up with what he calls"renewable petroleum".After that,he smiles,"It's a brave new world."
Mr.Pal is a senior director of LS9,one of several companies in or near Silicon Valley.The company is not interested in using corn as material,given the much-advertised problems created by using food crops for fuel.Instead,different types of agricultural waste will be used according to whatever makes sense for the local climate and economy:wheat straw in California,for example,or woodchip in the south.
Are Americans ready to be putting genetically changed bug excretion in their cars?"It's not the same as with food,"Mr.Pal say."We are putting these bacteria in a very isolated container.Their entire universe is in that tank.When we've done with them.they are destroyed."
"Besides",he says,"there is greater good being served.""I have two children,and climate change is something that they are going to face.The energy crisis is something that they are going to face.We have a collective responsibility to do this."

A.keep them in an isolated tank

A.it is a very complex process for bugs to produce oil
B.it is not worthwhile for Mr.Pal to do the experiment
C.it is safe to use the excretion produced by bugs
D.it is necessary to use bugs to produce crude oil
75.What would be the best title for the passage?A
A.Bugs Eat Waste and Excrete Petrol
B.Waste Turns into Crude Oil

D.Software Executive Turned to Bugs.
分析 本文说明了一个研究成果,即通过改变虫子的基因来达到让它们吃农业废弃物进而排泄出原油的目的.
解答 CBCA
72.答案 C 细节理解题.由文章第一段…says Greg Pal,33,a former software executive可知,Greg Pal原先是一位电脑软件开发人员.故答案为C
73.答案 B 细节理解题.文章第二段To be more accurate,the genetic(基因的) change of bugs,可知是改变虫子的基因,以达到让它们吃农业废弃物进而排泄出原油的目的.故答案为B
74.答案 C 推理判断题.由文章倒数第二段Greg Pal所说的话可知,这些虫子排泄的原油将被放在一个单独的容器中,不会损害汽车,是安全的.故答案为C
75.答案 A 主旨大意题.本文说明了这样一个研究成果,即通过改变虫子的基因来达到让它们吃农业废弃物进而排泄出原油的目的.故A项能恰如其分地概括本文的主题,其他选项都偏离了文章的主旨.故答案为A
点评 阅读理解题测试考生在阅读基础上的逻辑推理能力,要求考生根据文章所述事件的逻辑关系,对未说明的趋势或结局作出合理的推断;或根据作者所阐述的观点理论,对文章未涉及的现象、事例给以解释.考生首先要仔细阅读短文,完整了解信息,准确把握作者观点.
