Question

5．From a small warehouse in North Salt Lake City，Utah，a little-known company called Go Natural CNG is about to release a new home refueling system after more than two years of research．
The system，backed by technology giant Parker Hannifin Corp，will fill up quicker than some models-about one gallon an hour-and last up to 20 years，according to Go Natural CNG Chief Executive Lucas Kjar．The unit，expected by the end of the year，will use hydraulic technology to compress （压缩） the gas for vehicle use，he said．He did not say how much the unit would cost．
But Go Natural may have a lot of competition．General Electric，Whirlpool and Eaton are all working on home refueling technologies expected to be launched in the next couple of years．
General Electric，which received 1.8 million from the government to develop its system，aims to release a unit that will cool natural gas to minus 50 degrees Celsius to extract（提取）water an dother contaminates before refueling．GE aims to sell the unit at 500，about a tenth of the cost of current models．
General Electric said it was in the development phase and declined to comment on the program's progress．
Honda，which makes the natural gas-fired Honda Civic GX，has contacted GE and Whirlpool to discuss their plans，according to Elmer Hardy，Honda's senior manager of alternative fuel vehicles．
Eaton，which received 3.4millionfromthegovernmenttodevelopthetechnology，isworkingonaunitatitslabsinSouthfield，Michigan，thatwoulduseliquidstocompressthegasinsteadofthetraditionalmetalpistons（活塞）．Itaimstomakeaunitavailablefor500 by 2015．
"We are seeing if we can do it in a way that reduces the price point，"said Clark Fortune，who leads the program at Eaton．"The adoption will improve if the costs come down．"
46．What might be the author's purpose in writing the text？C
A．To encourage car owners to use natural gas．
B．To advertise some technology companies．
C．To introduce a new home refueling system．
D．To present some ways of saving energy．
47．Which company may be the first to release the new refueling system？D
A．Eaton            B．General Electric         C．Whirlpool            D．Go Natural
48．Which of the following is true of the system to be launched by Go Natural？A．It can be bought at $5oo now．
B．It has got into market this year．
C．It can be used for twenty years．
D．It is financed by Honda．
49．What is the government's attitude to the new home refueling system？D
A．Doubtful     B．Cautious          C．Negative         D．Supportive
50．What may prevent the system from being widely accepted according to Clark Fortune？B
A．Its refueling speed
B．Its present price．
C．Its compressing technique
D．Its appearance．

Answer 1

分析 本文是一篇说明文，主要说明了一个鲜为人知的公司经过两年多的研究即将推出一个新型的家用加油系统的相关信息．这项技术是由派克汉尼汾公司巨头公司支持研发的，加油速度比一般地模型要快，可以使用长达20年．'Go Natural CNG‘是第妨碍这个系统被广泛应用的问题可能是它的价格．一个推出这种技术的公司，并且面临众多的竞争，通用电器公司、惠而浦和伊顿公司都在研发家用加油技术，并有望在未来几年推出．政府对这一新的科技发明持支持的态度．

解答 46．C      推理判断题．文章第一段点明了主题，即一个鲜为人知的公司经过两年多的研究即将推出一个新型的家用加油系统．故选C项．
47．D      推理判断题．根据文章第三段"But Go Natural may have a lot of competition．General Electric，Whirlpool and Eaton are all working on home refueling technologies expected to be launched in the next couple of years"可知，‘Go Natural CNG'面临众多的竞争，通用电器公司、惠而浦和伊顿公司都在研发家用加油技术，并有望在未来几年推出．因此'Go Natural CNG‘可能是第一个推出这种技术的公司．故选D项．
48．C     细节理解题．根据文章第二段第一句中的"and last up to 20 years"可知，这个新型的加油系统可以使用长达20年．故选C项．
49．D    推理判断题．根据第四段的第一句"General Electric，which received 1.8 million from the government to develop its system"和第七段的第一句"Eaton，which received 3.4millionfromthegovernmenttodevelopthetechnology"可知，政府对这一新的科技发明持支持的态度．故选D项．
60．B    细节理解题．根据文章最后一段的"We are seeing if we can do it in a way that reduces the price point"及"The adoption will improve if the costs come down．"可知，妨碍这个系统被广泛应用的问题可能是它的价格．故选B项．

点评 解答细节理解题时，一个常用的方法就是运用定位法，即根据题干和选项中的关键词从原文中找到相关的句子，与选项进行比较从而确定答案；推理判断题既要求学生透过文章表面文字信息推测文章隐含意思，又要求学生对作者的态度、意图及文章细节的发展作正确的推理判断，力求从作者的角度去考虑，不要固守自己的看法或观点．
