我今日瀏覽論壇各貼，不期遇到不少談及以“不改變原意”為選擇答案標準的，方知此N年前之不知哪位教師隨口繆傳，居然被某些培訓機構(gòu)的教師奉為瑰寶，流毒至今，搞清楚這個問題，只須把它分拆成幾個子問題：

　　(1)應(yīng)該如何看待一道語法題目的A選項？

　　在直觀感受上，

　　A選項是有點特殊的，因為它被代入了題干，與不劃線的部分連成一體。所以，給考生形成了A代人后的句子代表了”原句“的錯覺。實際上，我們完全可以把一道GMAT語法題目看做一道填空題，即，題干的劃線部分是blank，你有5種選擇，需要從5種選擇中選擇一個填入這個blank。換言之，5個選項的地位是平等的，GMAC從來沒有給出過A的地位特殊的任何官方說法。

　　(2)為何多年之前會有正確答案不改變“原句”意思的說法？

　　很簡單 ，必須承認，雖然我們經(jīng)常強調(diào)“意合”，但是即便在新PREP中，5個選項意思都徹底不同的，畢竟是少數(shù)，更多的意思不同，都是體現(xiàn)在局部。更別說N年前

　　BY等前輩賴以分析的樣本了。所以，在那個年代的GMAT題目中，A選項和其它選項意思有差別的概率本來就很小，那是一個關(guān)注結(jié)構(gòu)的年代。也許因為這樣，為了在授課時候能多填充點內(nèi)容，這些前輩才給出這條荒謬之極的“不改變原意”規(guī)律。

　　(3 )什么才是真正的原意？

　　這個問題非常浩瀚。今天只能簡單地說一個最基本的判斷標準：正確的人做正確的事，修飾成分和被修飾成分正確對應(yīng)。舉2個例子：

　　1)The Environmental Protection Agency's proposal to place restrictions on both diesel fuel and diesel engines has sparked a counterattack by the oil industry, saying that the move will exacerbate the nation's fuel supply problems。

　　A. on both diesel fuel and diesel engines has sparked a counterattack by the oil industry, saying。

　　B. on both diesel fuel and engines have sparked the oil industry to counterattack, and they say。

　　C. on both diesel fuel and diesel engines has sparked a counterattack by the oil industry, which says。

　　D. both on diesel fuel and engines has sparked the oil industry to a counterattack, saying。

　　E. both on diesel fuel and diesel engines have sparked the oil industry to counterattack, and it says。

　　C和A的區(qū)別是啥？就是say這個動作到底是industry發(fā)出，還是全句的主語proposal 發(fā)出。這個時候不能根據(jù)A認為是saying，就把其它選項殺掉，而應(yīng)該根據(jù)全句的句意，判斷說出這話的應(yīng)該是industry，因為proposal不會自己反對自己，只有石油工業(yè)才會反對那個限制柴油機使用的proposal。這背后的判斷標準是什么？就是傳說中的邏輯，動作發(fā)出者與動作的合理對應(yīng)。

　　The ability of scientists to provide models of the atmosphere's complex responses to changing conditions, like seasonal and daily cycles or different planetary conjunctions, have become ever more accurate。

　　(A) The ability of scientists to provide models of the atmosphere's complex responses to changing conditions, like seasonal and daily cycles or different planetary conjunctions, have become ever more accurate。

　　(B) The ability of scientists has become ever more accurate in providing models of the atmosphere's complex responses to changing conditions, such as seasonal and daily cycles or different planetary conjunctions。

　　(C) Scientists have become able to provide ever more accurate models of the atmosphere's complex responses to such changing conditions as seasonal and daily cycles or different planetary conjunctions。

　　(D) Scientists have become ever more accurate in their ability for providing models of the atmosphere's complex responses to changing conditions, like seasonal and daily cycles or different planetary conjunctions。

　　(E) Scientists' ability to provide models of the atmosphere's complex responses to such changing conditions as seasonal and daily cycles or different planetary conjunctions have become ever more accurate。

　　請注意在每個選項里面accurate的修飾對象， ABE是能力， D是科學家，C是模型。不比不知道，一比就清楚了，應(yīng)該修飾的是模型。這道題目屬于選項意思之間差異較大的，但確定哪個意思正確，也不是依靠所謂的“原句”，而是修飾和被修飾者的合理對應(yīng)，比如你不能用婀娜來修飾男人，不能用精確來修飾眉毛，對嗎？

　　(4)A選項到底有沒有特殊地位？

　　這個問題只能作為猜想。對于命題者，這個是很好的調(diào)控難度的工具。如果想降低難度，把能反映句意的選項設(shè)為A，則能幫助考生較快獲得句意，如果想加大難度，則把唧唧歪歪的選項設(shè)為A。在這個問題上，主動權(quán)全部在GMAC。
