PREP-1-132

 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.

1. that CEO’s now earn an average of 419 times more pay than blue-collar workers, compared to a ratio of 42 times

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

3. that, on average, CEO’s now earn 419 times the pay of blue-collar workers, as compared to 42 times their pay, the ratio

4. CEO’s who now earn on average 419 times more pay than blue-collar workers, as compared to 42 times their pay, the ratio

5. CEO’s now earning an average of 419 times the pay of blue-collar workers, compared to the ratio of 42 times

答案选C

一直对ratio的比较不是很清楚,怎么个平行法?还有,这里的earn是名词么?

我觉得BY语法上说倍数的表达只有四种：如果用twoice做例子话就是：

twice as much as, twice as many as, twice+名词，twice+that从句

因此，A和D就可以排除了。

然后看E选项没有表示现在进行时的时间标志。并且D和E没有用that引导定于从句错。

至于B和C，我觉得C又用了上面那个结构，所以对吧。B的as compared to结构错了吧？这个问题不确定。
