谢谢了~

米有人解释一下么

我看到过2个版本的正确答案: B or C.... 我也很郁闷，同问，到底哪个是正确的？

谢谢sjjay~~总算想通了~~！~\(≧▽≦)/~花花

B.      that, on average, CEO’s now earn 419 times the pay of blue-collar workers, a ratio that compares to 42 times

其中 a ratio 和42 times不平行

这个是SC-PREP里的题，详解版里解释如下：

132. (31556-!-item-!-188;#058&004545)

A recent review of pay scales indicates that CEO's now earn an average of 419 times more pay than blue-collar workers, compared to a ratio of 42 times in 1980.

(A) that CEO's now earn an average of 419 times more pay than blue-collar workers, compared to a ratio of 42 times

(B) that, on average, CEO's now earn 419 times the pay of blue-collar workers, a ratio that compares to 42 times

(C) that, on average, CEO's now earn 419 times the pay of blue-collar workers, as compared to 42 times their pay, the ratio

(D) CEO's who now earn on average 419 times more pay than blue-collar workers, as compared to 42 times their pay, the ratio

(E) CEO's now earning an average of 419 times the pay of blue-collar workers, compared to the ratio of 42 times

句子结构：A recent review… indicates that…, CEO’S earn…, as compared to… 主语是review，谓语是indicates，后跟that引导的宾语从句说明indicate的内容，宾语从句的主语是CEO’s，谓语是earn，宾语是419 times the pay of blue-collar workers，后跟比较结构as compared to…，the ratio是42 times their pay的同位语。
                    

CEO’s是CEO的复数形式，以缩写字母组成的专有名词的复数形式可以是加’s或加s。
                

考点：比较、句子结构
                

比较-compare/contrast的用法，(as) compared to/with（GMAT没有区分to和with的区别），省略了主语和系动词，即A be compared with/to B，与in contrast to都是惯用法，前后比较对象一定要对等。常见的错误用法有：将compare用作主动(when compare…; comparing…)，比较对象不对等。
                

句子结构-宾语从句，正式书面语中，宾语从句的引导词that不能省略。
                

(A) compared to的比较对象不对象，前者419 times the pay of blue-collar workers表达的是工资数，而后者a ratio of是比率。
                

(B) a ratio that compares的compare不能用主动方式表达，应该是被比较sth be compared to…的省略形式（省略了主语和系动词，是惯用法）；compare to的比较对象不对象，前者419 times the pay of blue-collar workers表达的是工资数，而后者42 times是比率。
                

(C) 正确，as compared to比较结构，419 times the pay与42 times their pay比较，the ratio…是同位语。
                

(D) 缺少that引导宾语从句；indicates CEO’s who…句子结构不完整，缺少谓语，who引导定语从句修饰名词CEO’s。
                

(E) 缺少that引导宾语从句；indicates CEO’s earning…句子结构不完整，缺少谓语；compare to的比较对象不对象，前者419 times the pay of blue-collar workers表达的是工资数，而后者42 times是比率。
