※ 引述《eronjay (小比)》之銘言： : 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 : 想請問一下(D)選項除了用慣用語target at解外, all of them...an invading是否也是 : 一個考點?如果是,為什麼all of them...an invading是錯的? 從 prize for 之後的句意簡述: Dr. T 贏得了諾貝爾獎 - 因為發現了人體如何持續的改變基因， 來製造出看似無窮多的抗生素， 每一個 (抗生素) 都很特殊的針對一項入侵的微生物或外在物質 如上面的版友推文所述，all of them targeted to an invading microbe 則沒有強調 1 to 1 --> 1 antibody to 1 microbe or substance 而句意則會變成 all to 1 OG 2015 #61 題也是一個好例子: http://gmat.kaomanfen.com/question/2681oh.html 正確答案: 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. 為何要特別註明這些黃底的字呢? OG 是這麼解釋的: 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. 句意是強調對比: 所有的 state 都面臨相似的情況， 但每一個 state 的工業會自己決定....(省略) 所以當強調每個個體都有特殊性的時候， 用 each 會比 all 來的清楚許多 -- Keewee 修辭專班: http://ndxica.pixnet.net/blog/post/41829760 Donz + Keewee 四週速成實力4月班: http://ppt.cc/2oGt Donz GMAT FB: https://www.facebook.com/groups/DonzGMAT --
