※ 引述《eronjay (小比)》之铭言： : Dr. Tonegawa won the Nobel Prize for discovering how the body can constantly : change its genes to fashion a seeming unlimited number of antibodies. each : specifically targeted at an invading microbe or foreign : substance. : (A) seeming unlimited number of antibodies, each specifically targeted at : (B) seeming unlimited number of antibodies, each targeted specifically to : (C) seeming unlimited number of antibodies, all specifically targeted at : (D) seemingly unlimited number of antibodies, all of them targeted : specifically to : (E) seemingly unlimited number of antibodies, each targeted specifically at : 想请问一下(D)选项除了用惯用语target at解外, all of them...an invading是否也是 : 一个考点?如果是,为什麽all of them...an invading是错的? 从 prize for 之後的句意简述: Dr. T 赢得了诺贝尔奖 - 因为发现了人体如何持续的改变基因， 来制造出看似无穷多的抗生素， 每一个 (抗生素) 都很特殊的针对一项入侵的微生物或外在物质 如上面的版友推文所述，all of them targeted to an invading microbe 则没有强调 1 to 1 --> 1 antibody to 1 microbe or substance 而句意则会变成 all to 1 OG 2015 #61 题也是一个好例子: http://gmat.kaomanfen.com/question/2681oh.html 正确答案: While all states face similar industrial waste problems, the predominant industries and the regulatory environment of each state obviously determine the types and amounts of waste produced, as well as the cost of disposal. 为何要特别注明这些黄底的字呢? OG 是这麽解释的: The sentence begins with the conjunction while, here used to mean although, and contrasts the similar situation of all states with the varying conditions of each state. So it is more logical and correct to have the regulatory environment of each state. 句意是强调对比: 所有的 state 都面临相似的情况， 但每一个 state 的工业会自己决定....(省略) 所以当强调每个个体都有特殊性的时候， 用 each 会比 all 来的清楚许多 -- Keewee 修辞专班: http://ndxica.pixnet.net/blog/post/41829760 Donz + Keewee 四周速成实力4月班: http://ppt.cc/2oGt Donz GMAT FB: https://www.facebook.com/groups/DonzGMAT --
