m总体分析英语知识运用部分的短文选自2005年6月2日的TheEconomist（《经济学人》），原文标题为“TheEvolutionofIntelligence:NaturalGenius?"（《智力的进化天生我才？》）。本文主要介绍了科学家格雷戈里■科克伦的观点：人类的某些族群比其他族群智商更高，而这些族群的智商与遗传疾病密切相关。从题目来看，20个题目中有17个考查语言要素，只有3个考查语段特征。这说明考研英语的英语知识运用部分重心在向语言要素方面转移，这一点我们需要注意。IH1英汉对照OTheideathatsomegroupsofpeoplemaybemoreintelligentthanothersisoneofthosehypothesesthatdarenotspeakitsname.©ButGregoryCochranis(1)preparedtosayitanyway.❸Heisthat(2)rarebird,ascientistwhoworksindependently(3)ofanyinstitution.❹Hehelpedpopularizetheideathatsomediseasesnot(4)previouslythoughttohaveabacterialcausewereactuallyinfections,whicharousedmuchcontroversywhenitwasfirstsuggested.0(5)Evenhe,however,mighttrembleatthe(6)thoughtofwhatheisabouttodo.©Togetherwithanothertwoscientists,heispublishingapaperwhichnotonly(7)suggeststhatonegroupofhumanityismoreintelligentthantheothers,butexplainstheprocessthathasbroughtthisabout.❸Thegroupin(8)questionareaparticularpeopleoriginatedfromcentralEurope.❹Theprocessisnaturalselection.OThisgroupgenerallydowellinIQtest,(9)scoring12-15pointsabovethe(10)meanvalueof100,andhavecontributed(11)disproportionatelytotheintellectualandculturallifeoftheWest,asthe(12)careersoftheirelites,includingseveralworld-renownedscientists,(13)affirm.❷Theyalsosuffermoreoftenthanmostpeoplefromanumberofnastygeneticdiseases,suchasbreastcancer.©Thesefacts,(14)however,havepreviouslybeenthoughtunrelated.©Theformerhasbeen(15)putdowntosocialeffects,suchasastrongtraditionof(16)valuingeducation.©Thelatterwas人类的某些族群可能比其他族群智商更高，这一观点是众多不敢明说的假设之一。但是格雷戈里•科克伦（1）准备无论如何也要将它公开。科克伦是那种（2）特立独行的人,是一位不隶属（3）壬任何机构的科学家。他曾帮助普及这样一种观点：某些（4）以前被认为并非由细菌引起的疾病，实际上是传染病。这个观点一经提出就引起了很大的争议。然而，（5）即使是科克伦自己...
