2017年雅思阅读考试精选习题及答案(4)
1. The transcription needs a certain amount of editing,as even if the computer can tell the difference between words of similar sounds such as write and right,it is still not yet able to do the work as well as an intelligent secretary.
第一层：The transcription 主 needs 谓 a certain amount of 定 editing,宾 as even if the computer can tell the difference between words of similar 状语从句
sounds such as write and right， it is still not yet able to do the work as well as an intelligent secretary.
第二层：(状语从句)as 引 even if the computer can tell the difference between words of similar sounds such as write and right,状语从句1 it 主 is 系 still not yet 状 able 表 to do the work 宾 as well as an inte- lligent secretary . 状语从句2
第三层：(状语从句1)even if 引 the computer 主 can tell 谓 the difference 宾 between words of similar sounds 定 such as write and right 同位语
(状语从句2)as well as 引 an intelligent secretary 主
要点 本句中as引导原因状语从句，其中该句还带有一个由even if引导的让步状语从句;介词短语between words of similar sounds修饰difference，such as write and right修饰words，as well as……为同等比较状语从句，其中省略了与主句相同的部分。intelligent：有才智的;理解力强的。
译文 译稿需要一定量的编辑工作，因为，即使计算机能够区别同音异义词，如 write和right，它仍不可能把这项工作做得像有思维能力的秘书那样好。

Talc Powder
A Peter Brigg discovers how talc from Luzenac's Trimouns in France find its way into food and agricultural products - from chewing gum to olive oil. High in the French Pyrenees, some 1,700m above sea level, lies Trimouns, a huge deposit of hydrated magnesium silicate - talc to you and me. Talc from Trimouns, and from ten other Luzenac mines across the globe, is used in the manufacture of a vast array of everyday products extending from paper, paint and plaster to cosmetics, plastics and car tyres. And of course there is always talc's best known end use: talcum powder for babies1 bottoms. But the true versatility of this remarkable mineral is nowhere better displayed than in its sometimes surprising use in certain niche markets in the food and agriculture industries.
B Take, for example, the chewing gum business. Every year, Talc de Luzenac France - which owns and operates the Trimouns mine and is a member of the international Luzenac Group (art of Rio Tinto minerals) supplies about 6,000 tones of talc to chewing gum manufacturers in Europe. "We've been selling to this sector of the market since the 1960s," says Laurent Fournier, sales manager in Luzenac's Specialties business unit in Toulouse. "Admittedly, in terms of our total annual sales of talc, the amount we supply to chewing gum manufactu...

2017年雅思阅读考试精选习题及答案(2)
1 NEELIE KROES, the European Union’s competition commissioner, did not mince her words when reporting on Europe’s energy markets on Wednesday January 10th. Europe’s energy firms have failed to invest in networks and so customers are suffering. Those “vertically integrated” energy companies such as Electricité de France (EDF) or Germany’s E.ON, widely dubbed as “national champions”, are effectively behaving like local monopolies. Shy of competition, eager for artificially high prices, they are helping to block the efficient generation, transmission and distribution of energy on the continent.
2 Energy prices vary wildly across Europe. Ms Kroes wants to see cheaper energy, and intends to push suppliers to divest their distribution network and to get them to invest more in transportation systems so that more energy—in the form of gas, or electricity, for example—can flow easily over borders. It is remarkably hard, for example, for gas-poor Germany to import from the neighbouring, gas-rich Netherlands. Companies that dominate national markets have, so far, had little interest in improving the interconnections which would mean lower prices for consumers across the continent.
3 Ms Kroes, of course, will struggle to get her way. The European Commission, which on the same day presented its recommendation for improving EU energy p...

From The Economist print edition
1 REFRIGERATORS are the epitome of clunky technology: solid, reliable and just a little bit dull. They have not changed much over the past century, but then they have not needed to. They are based on a robust and effective idea--draw heat from the thing you want to cool by evaporating a liquid next to it, and then dump that heat by pumping the vapour elsewhere and condensing it. This method of pumping heat from one place to another served mankind well when refrigerators' main jobs were preserving food and, as air conditioners, cooling buildings. Today's high-tech world, however, demands high-tech refrigeration. Heat pumps are no longer up to the job. The search is on for something to replace them.
2 One set of candidates are known as paraelectric materials. These act like batteries when they undergo a temperature change: attach electrodes to them and they generate a current. This effect is used in infra-red cameras. An array of tiny pieces of paraelectric material can sense the heat radiated by, for example, a person, and the pattern of the array's electrical outputs can then be used to construct an image. But until recently no one had bothered much with the inverse of this process. That inverse exists, however. Apply an appropriate current to a paraelectric material and it wil...
