雅思备考环境科技类：经济学人精读

　　雅思阅读大致分为生物、地理和社会科学三类。其中，地理类的环境话题出题频率非常高，如果再和科技相关内容结合，会给考生造成很大的阅读困难，尤其是其中的专有名词和专业知识大大降低了考生的阅读速度。今天课窝网和大家分享一篇“环境+科技”类的好文精读！

　　以下是June 9th-15thThe Economist上的一篇文章“Climate change--The power of negative thinking”，一些地道用词、搭配已总结，便于考生积累，同时熟悉此类话题的预感和难度。

　　Extractingcarbon dioxidefromthe atmosphere is possible. Butatwhat cost?

　　extract…from…从…抽出（榨取汁液,提炼金属,摘抄摘录）；at…cost以…为代价（注意介词搭配，避免雅思作文在细节处丢分）

　　In Maysome 250 scientists from around the worldconvenedin Gothenburg, Sweden, to discuss a dirty

　　secretof the three-year-old Paris climate agreement.Virtuallyall simulations whichchartpaths towardmeetingthatcompact’s goalassume not just a sharp reduction in actual emissions butalso the removal of carbon dioxide from the atmosphereon a massive scale.

　　convene开会；virtually事实上（=actually/really/almost）;chart绘制、标示；meet…goal注意实现目标的动词用meet，也可用achieve/realize（考生需在备考雅思时重视同义替换）；on amassive scale大规模

　　Onereason why such “negative emissions” have been absent from climate discussions isthat no one has a good idea of how exactly tobring them about.The obvious solution is to plant lots oftrees, toconvertCO2intowood. But this would mean foresting an area with a sizesomewhere between that of India and Canada.

　　bring about实现,带来,造成；一句话中有两个从句，这在雅思阅读中极大地增加了阅读难度，在雅思作文中这类语法句型的多样性是高分的重点；Convert…into…把..转化为…（和change,alter等一起记）

　　DrKeith and his colleagues argue in a paper that the CO2 removal technique theyhave been perfecting is nopipe dream—evenif it does contain pipesaplenty. Theirprocess has several steps. First, air is channeled by fans onto ahoneycombedplasticslabcalled acontactor…

　　pipe dream白日梦；aplenty丰富地（这里利用pipe一词幽默了一下）；Honeycombed蜂巢状；slab厚板；contactor开关（雅思阅读也有这个习惯：给出一个生词，但是会加以解释，不会影响考生理解文章内容）

　　Ifthat all sounds complicated,chemically speakingit is not. Nor is the idea new. A researcher came up with the principles 20years ago and Dr Keithpatentedhis versionin 2015.A pilot plantwith a contactorthree by five metres across and three metres deephas been running for three years. It extracts a tonne of carbon dioxide fromthe air per day.

　　xxx speaking从…方面来说（General speaking一般来说）；patent得到…专利；A pilotplant试验工厂（雅思阅读中也经常出现“单词好像都见过，但是不清楚是什么意思”的情况，很多词的多种意思都要尽量掌握）；three byf ive metres across and three metres deep3×5米宽，3米深
