劍橋雅思11test1passage3閱讀答案及解析
第27題選:D
對應原文:D段:The idea is modelled on historic volcanic explosions
答案解析:這道題因為沒有明顯的定位詞,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對應,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
對應原文: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一步說明。即地球工程的成功應用,由此確定答案為B。
第29題選:A
對應原文: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
對應原文: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
對應原文: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
對應原文:同上
答案解析:encourgae與stimulate同義替換,雖然我們可能不認識algae是什么意思,但通過修飾關系,仍然可以確定它是答案。
第33題選:clouds
對應原文: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
對應原文: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
對應原文: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
對應原文: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
對應原文: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認為,如果我們在某一天停止地球工程,那么地球很快就會回到工程實施之前的狀態(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
對應原文: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的觀點是,我們不應該排除對這一方案及其可能性的徹底思考。即承認地球工程雖然存在一些缺點,但仍然是值得探索的。由此確定答案。
第39題選:C
對應原文:G段:Lunt says Angel’s project would have to operate at half strength
答案解析:Lunt認為Angel的項目必須以一半的強度運營。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
對應原文: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對應,由此確定答案為A。
