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 （壓縮） 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�。﹚ater 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．

Answer 1

分析 本文是一篇說明文，主要說明了一個(gè)鮮為人知的公司經(jīng)過兩年多的研究即將推出一個(gè)新型的家用加油系統(tǒng)的相關(guān)信息．這項(xiàng)技術(shù)是由派克漢尼汾公司巨頭公司支持研發(fā)的，加油速度比一般地模型要快，可以使用長達(dá)20年．'Go Natural CNG‘是第妨礙這個(gè)系統(tǒng)被廣泛應(yīng)用的問題可能是它的價(jià)格．一個(gè)推出這種技術(shù)的公司，并且面臨眾多的競(jìng)爭(zhēng)，通用電器公司、惠而浦和伊頓公司都在研發(fā)家用加油技術(shù)，并有望在未來幾年推出．政府對(duì)這一新的科技發(fā)明持支持的態(tài)度．

解答 46．C      推理判斷題．文章第一段點(diǎn)明了主題，即一個(gè)鮮為人知的公司經(jīng)過兩年多的研究即將推出一個(gè)新型的家用加油系統(tǒng)．故選C項(xiàng)．
47．D      推理判斷題．根據(jù)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'面臨眾多的競(jìng)爭(zhēng)，通用電器公司、惠而浦和伊頓公司都在研發(fā)家用加油技術(shù)，并有望在未來幾年推出．因此'Go Natural CNG‘可能是第一個(gè)推出這種技術(shù)的公司．故選D項(xiàng)．
48．C     細(xì)節(jié)理解題．根據(jù)文章第二段第一句中的"and last up to 20 years"可知，這個(gè)新型的加油系統(tǒng)可以使用長達(dá)20年．故選C項(xiàng)．
49．D    推理判斷題．根據(jù)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，政府對(duì)這一新的科技發(fā)明持支持的態(tài)度．故選D項(xiàng)．
60．B    細(xì)節(jié)理解題．根據(jù)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，妨礙這個(gè)系統(tǒng)被廣泛應(yīng)用的問題可能是它的價(jià)格．故選B項(xiàng)．

點(diǎn)評(píng) 解答細(xì)節(jié)理解題時(shí)，一個(gè)常用的方法就是運(yùn)用定位法，即根據(jù)題干和選項(xiàng)中的關(guān)鍵詞從原文中找到相關(guān)的句子，與選項(xiàng)進(jìn)行比較從而確定答案；推理判斷題既要求學(xué)生透過文章表面文字信息推測(cè)文章隱含意思，又要求學(xué)生對(duì)作者的態(tài)度、意圖及文章細(xì)節(jié)的發(fā)展作正確的推理判斷，力求從作者的角度去考慮，不要固守自己的看法或觀點(diǎn)．
