暗夜特使

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 time

答案好像是选C，也有人说选B

但是我觉得不管是C还是B，其中CEO's now earn有点怪怪的。我认为CEO ‘s是 CEO is的缩写，那不应该是CEO is now earning 吗？？

CEO's 是复数的表达，就是一堆CEO，不是一个CEO。在规范英语里，是绝对不可能把is 缩写成's来表达的
