先把两个题目贴上。

D.It took less than 35 years from the release of African honeybees outside Sao Paulo, Brazil, when
E.It took less than the 35 years after the time that African honeybees were released outside Sao Paulo, Brazil, and then正确答案A
解释： (A) 正确, after + n.结构避免了逻辑主语问题; less than 35 years after …符合习惯用法

第85题
In 1945, after a career as First Lady in which she shattered expectations more audaciously than either Abigail Adams or Dolly Madison ever had been, Eleanor Roosevelt was appointed a delegate to the United Nations General Assembly by President Harry S Truman.

A.more audaciously than either Abigail Adams or Dolly Madison ever had been, Eleanor Roosevelt was appointed a delegate to the United Nations General Assembly by President Harry S Truman

B.more audaciously than either Abigail Adams or Dolly Madison, President Harry S Truman had Eleanor Roosevelt appointed to be a delegate to the United Nations General Assembly
C.with an audacity never matched in the case of Abigail Adams or Dolly Madison, President Harry S Truman had Eleanor Roosevelt appointed as a delegate to the United Nations General Assembly
D.with an audacity never matched by Abigail Adams or Dolly Madison, Eleanor Roosevelt was appointed a delegate to the United Nations General Assembly by President Harry S Truman
E.with an audacity never matched either in the case of Abigail Adams or of Dolly Madison's, Eleanor Roosevelt was appointed to be a delegate to the United Nations General Assembly by President Harry S Truman正确答案D
答案中对于B选项错误的原因解释是：

(B) President Harry S Truman作为after a career as First Lady的逻辑主语,不符合逻辑.


问题来了。 同样是after + n 结构， 为什么一个没有逻辑主语问题另外一个却有呢

PLUS： 这个问题我在论坛里面看了，有人讨论过： http://forum.chasedream.com/GMAT_SC/thread-645735-1-1.html?postid=15796155&searchmode=TopicContent&searchtext=In 1945 after a career
但是我看了之后总结起来就一句话“靠感觉。。。。。！！！！！！！！！！！！” 有没有更靠谱点的解释？

比较赞同LZ贴的帖子里的那个说法=。=

第一题的after介词短语做定语修饰35years所以避免了逻辑主语的匹配
第二期after介词短语放在句首做状语修饰主句要考虑逻辑主语是否匹配
