错选A，应选C
A study on couples' retirement transitions found that women who took new jobs after retiring from heir 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
※句子结构：study found that… women… reported high marital satisfaction， more so than those…
主词是study，动词是found，后跟that引导的受词子句说明found的内容。
【考点】比较、逻辑表达、平衡对称
比较，相同比较对象对比，第二个名词由相应的代词指代，要注意单复数形式。
逻辑表达-维持原句意思，比较结构中的代词指代对象要注意是否符合逻辑意思，并且是否表达原句所要表达的意思。
平衡-形容词子句，在比较句子中比较对象的修饰成分最好用相同的表达方式，以使句子更加平衡对称。
(A) 缺少指代women的代词，致使more than的比较对象不对等，satisfaction与when retiring对比。
(B) they指代前面的women，表达意思错误，因为if they were to retire表达了同一群妇女不同情况下的satisfaction对比，改变了原句意思，原句要表达的是不同妇女不同情况下的satisfaction对比；more than前后不平衡。
(C) 正确，those指代women，who took和who retired平衡。
(D) which与so都指代satisfaction，重复；
(E) they指代前面的women，表达意思错误，与A选项相同；没有特殊的时间标志说明需要用过去完成时had retired。
上面是prep的详解，但是我还是不太懂啊！总感觉satisfaction是比较的重点；还有B 选项中那个so是指代什么啊？ 请教各路大侠！ |
