A recently published report indicates that the salaries of teachers continue to lag far behind other college-educated professionals, because they make an average of nearly $8,000 a year less at the start of their careers and almost $24,000 less a year by the time they reach the age of 50.
A.other college-educated professionals, because they make an average of nearly $8,000 a year less at the start of their careers and almost $24,000 less
B.other college-educated professionals, by an average of nearly $8,000 a year at the start of their careers, to almost $24,000
C.what other college-educated professionals are paid—making an average of nearly $8,000 a year less at the start of their careers and almost $24,000 less
D.those of other college-educated professionals—by an average of nearly $8,000 a year at the start of their careers to almost $24,000 less
E.those of other college-educated professionals—by an average of nearly $8,000 a year at the start of their careers, and by almost $24,000
答案是E没有问题，但我不理解，为什么D错，看了就得prep解释为lag far behind 与less重复，我不明白破折号外的跟破折号里的为什么会算作语义重复，忘牛牛指点，感激不尽。 作者: wyyavv 时间: 2012-2-16 20:39

谢谢楼上的回答，我就从平行考虑吧，nearly $8,000 a year at the start of their careers, and by almost $24,000对于D，8000没有less那么24000也不能有less作者: hongnilvyi 时间: 2012-2-25 16:27
E.those of other college-educated professionals—by an average of nearly $8,000 a year at the start of their careers(,) and by almost $24,000
为什么要加逗号呢 又不是句子的并列或者三个或三个以上的短语的并列
所以就直接选d了
求教丫
