最近有同学问到平衡概念对等这个考点，通常概念对等要看句意， 但是有时候我们也可以从一些简单的方法判断，好比说实义名词和抽象名词， 这里A2简单整理相关考点如下： 一般性名词（实义名词） vs 动作名词（抽象名词） 平衡概念对等下，一般性名词尽量与一般性名词平衡，动作名词尽量与 动作名词平衡 Prep2012-Pack1-SC-062 VSC002507 KEY:C Narwhals can be called whales of the ice: in icy channels, ponds, and ice-shielded bays they seek sanctuary from killer whales, their chief predator, and their annual migrations following the seasonal rhythm of advancing and retreating ice. A. their annual migrations following C. their annual migrations follow 注解: 这题会在A/C纠结，注意killer whales, their chief predator, and their annual migrations并非是三个名词的平衡，因为一般性名词 killer whales/predator和动作名词migrations平衡概念不对等，their chief predator是killer whales的同位语，答案C是复合句，and後面接第 二个主要子句，主词是their annual migrations，动词是follow。 OG12-119 KEY:B New theories propose that catastrophic impacts of asteroids and comets may have caused reversals in the Earth's magnetic field, the onset of ice ages, splitting apart continents 80 million years ago, and great volcanic eruptions. B. the splitting apart of continents E. continents that were split apart 注解: the splitting是动作名词，continents是一般性名词，这里是四个 动作名词的受词平衡 Unlike/Like A, B +V….结构下，通常要看A/B有无可比性，通常都是 一般性名词，避免动作名词，另外一般性名词和动作名词在此结构下通常可 比性输给一般性名词对一般性名词 OV2-32. KEY:A Like Rousseau, Tolstoi rebelled against the unnatural complexity of human relations in modern society. (A) Like Rousseau, Tolstoi rebelled (B) Like Rousseau, Tolstoi's rebellion was 注解: rebellion是动词rebel 变化而来的抽象名词 OV2-66.KEY:D Unlike auto insurance, the frequency of claims does not affect the premiums for personal property coverage, but if the insurance company is able to prove excessive loss due to owner negligence, it may decline to renew the policy. (A) Unlike auto insurance, the frequency of claims does not affect the premiums for personal property coverage, (D) Unlike the premiums for auto insurance, the premiums for personal property coverage are not affected by the frequency of claims, 注解: the frequency是be frequent变化而来的抽象名词 -- A2GMAT一个月精修班 五年来超过400位精修班同学取得700+高分, 申请上Dream school！ 若您发现既有解法已无法让答题状况改善,或仍旧在重考漩涡打转, 请参考以下连结 http://a2gmat.blogspot.tw/p/02.html 让A2助你一举突破瓶颈上700! --
