A study on couples' retirement transitions found that women who took new jobs after retiring from their primary careers reported high marital satisfaction, more than when retiring completely.
A study on couples' retirement transitions found that women who took new jobs after retiring from their primary careers reported high marital satisfaction, more than when retiring completely.
(A) more than when retiring (B) more than if they were to retire (C) more so than those who retired (D) which was more so than those retiring (E) which was more than if they had retired
整句还原后是(the women who took...repoted) more (high marital satisfaction) than (did)those who retired. 这里satisfaction 和those(women)属于不同类的对象,不会引起歧义,所以即便在比较主语,同时又出现了宾语的情况下,did也是可以省略的。
