劍橋雅思11test1passage3閱讀答案及解析

第27題選：D

對(duì)應(yīng)原文：D段：The idea is modelled on historic volcanic explosions

答案解析：這道題因?yàn)闆]有明顯的定位詞，因此難度較大。我們只能從列舉各種地球工程的B段，C段和D段中尋找。發(fā)現(xiàn)historic可以和題干中的earlier對(duì)應(yīng)，而volcanic explosions也是一種自然現(xiàn)象，由此確定答案為D。

第28題選：B

對(duì)應(yīng)原文：B段：Geo-engineering has been shown to work,at least on a small localised scale.For decades,May Day parades in Moscow have taken place under clear blue skies,aircraft having deposited dry ice,silver iodide and cement powder to disperse clouds.

答案解析：B段開頭提到地球工程在本地范圍已經(jīng)被證明有效，隨后利用莫斯科五一游行的例子進(jìn)一步說明。即地球工程的成功應(yīng)用，由此確定答案為B。

第29題選：A

對(duì)應(yīng)原文：A段：Consequently,an increasing number of scientists are beginning to explore the alternative of geo-engineering–a term which generally refers to the intentional large-scale manipulation of the environment.

答案解析：A段中提到了地球工程的定義。該詞匯通常用來指國際性的，對(duì)環(huán)境的大范圍操控。即地球工程的定義，由此確定答案。

第30題選：sunshade

對(duì)應(yīng)原文：B段：His scheme would employ up to 16 trillion minute spacecraft,each weighing about one gram,to form a transparent,sunlight-refracting sunshade in an orbit 1.5 million km above the Earth.

答案解析：根據(jù)spacecraft定位到B段的這一句，原文中的form與題干上的create同義替換，排除掉其他修飾詞之后，確定答案為sunshade。

第31題選：iron

對(duì)應(yīng)原文：C段：depositing iron in the ocean to stimulate the growth of algae

答案解析：雖然這道題沒有什么提示詞，但根據(jù)30題和33題的位置，我們可以將注意力集中在C段上。depositing與place同義替換，再加上這一段中只有這一句提到往海洋里放什么東西，由此確定答案為iron。

第32題選：algae

對(duì)應(yīng)原文：同上

答案解析：encourgae與stimulate同義替換，雖然我們可能不認(rèn)識(shí)algae是什么意思，但通過修飾關(guān)系，仍然可以確定它是答案。

第33題選：clouds

對(duì)應(yīng)原文：D段：The concept of releasing aerosol sprays…so that sulphur dioxide would form clouds,which would,in turn,lead to a global dimming.

答案解析：根據(jù)aerosol sprays定位到D段，form與create同義替換，由此鎖定答案為clouds。

第34題選：cables

對(duì)應(yīng)原文：D段：it’s possible to preserve the ice sheets of Greenland with reinforced high-tension cables,preventing icebergs from moving into the sea.

答案解析：根據(jù)Greenland定位到D段的這一句話，strong與reinforced同義替換，由此確定答案為cables.

第35題選：snow

對(duì)應(yīng)原文：D段：Whereas the region’s native evergreen pines shade the snow and absorb radiation,birches would shed their leaves in winter,thus enabling radiation to be reflected by the snow.

答案解析：根據(jù)Russian Arctic和leaves定位到這句話。題干中問的是什么反射輻射，由此鎖定snow。

第36題選：rivers

對(duì)應(yīng)原文：D段：Re-routing Russian rivers to increase cold water flow to ice-forming areas could also be used to slow down warming,say some climate scientists.

答案解析：根據(jù)后一單元格的ice-forming定位到這句話，change the direction與re-routing同義替換，由此確定答案為rivers.

第37題選：B

對(duì)應(yīng)原文：E段：Dr Phil Rasch…if we were to end geo-engineering on a given day,then the planet would return to its pre-engineered condition very rapidly,and probably within ten to twenty years.

答案解析：Phil Rasch認(rèn)為，如果我們?cè)谀骋惶焱Ｖ沟厍蚬こ?，那么地球很快就?huì)回到工程實(shí)施之前的狀態(tài)。題干中的not be long-lasting與rapidly同義替換，由此確定答案為B。

第38題選：D

對(duì)應(yīng)原文：H段：According to Dr Martin Sommerkorn…we shouldn’t exclude thinking thoroughly about this topic and its possibilities

答案解析：Martin Sommerkorn的觀點(diǎn)是，我們不應(yīng)該排除對(duì)這一方案及其可能性的徹底思考。即承認(rèn)地球工程雖然存在一些缺點(diǎn)，但仍然是值得探索的。由此確定答案。

第39題選：C

對(duì)應(yīng)原文：G段：Lunt says Angel’s project would have to operate at half strength

答案解析：Lunt認(rèn)為Angel的項(xiàng)目必須以一半的強(qiáng)度運(yùn)營。即必須限制某些地球工程的功效。由此確定答案為C。

第40題選：A

對(duì)應(yīng)原文：E段：Angel says that his plan is‘no substitute for developing renewable energy

答案解析：Angel說，他的計(jì)劃并不是開發(fā)開再生能源的替代品。其中substitute與replace同義替換，renewable energy與non-fossil-based fuels對(duì)應(yīng)，由此確定答案為A。
