各位大牛看过来！关于SVO，ing！！！！

Ron曾经阐述了使用comma+ing的条件，
即
1) it should apply most nearly to the subject of the preceding clause (as you've said);and, even more importantly,
2) it should have one of the following RELATIONSHIPS to that clause:
* immediate consequence
* simultaneous, but lower-priority, action

OG13-35
By 1940, the pilot Jacqueline Cochran held seventeen
official national and international speed records, and
she earned them at a time when aviation was still so
new for many of the planes she flew to be of
dangerously experimental design,
(A) and she earned them at a time when aviation
was still so new for many of the planes she flew
to be
(B) earning them at a time that aviation was still so
new for many of the planes she flew to be
(C) earning these at a time where aviation was still
so new that many of the planes she flew were
(D) earned at a time in which aviation was still so
new such that many of the planes she flew were
(E) earned at a time when aviation was still so new
that many of the planes she flew were
答案是E。
OG对B项的解释是：Here, the word earning takes the pilot herself, not the records, as its subject. However, earning is close to the records, not to Jacqueline Cochran, making this sentence hard to process. In addition, the causal relationship between aviation being new and planes being of experimental design is more effectively communicated by the structure so new that many X were Y, not by the structure so new for many Y to be X.
按照Ron的条件，earning them at a time完全满足。earning可以视为和held同时发生，且apply to  the subject。也就是对的，为什么OG却说是不对的，有可能修饰records.还有一种说法是earn离主语太远造成修饰歧义，在我看来这跟OG13-29题相比较已经算近的了。
OG13-29
Emily Dickinson’s letters to Susan Huntington Dickinson were written over a period beginning a few years before Susan’s marriage to Emily’s brother and ending shortly before Emily’s death in 1886, outnumbering her letters to anyone else.
为什么还会产生修饰歧义？
我有两个问题不明白：
V-ing是离主语太远还是离主句谓语太远会产生歧义？
这个距离怎么判断？
各位牛牛，ing问题纠结半天了，越看越糊涂，帮帮我吧

"按照Ron的条件，earning them at a time完全满足。earning可以视为和held同时发生，且apply to  the subject。也就是对的，为什么OG却说是不对的，有可能修饰records."


同学啊，注意语义。comma + v-ing 到底表示什么逻辑意思？


"He read OG for eight times, hoping for a stellar GMAT score. "
This sentence makes sense.


"He read OG for eight times, doing all the prep questions."
This sentence does NOT make sense.


这题就属于后一种情况，如果你用v-ing，that does not make sense.
从语义上讲，后面那一串，讲的是international speed records怎么earned的，所以用 comma + v-ed 作为noun modifier修饰international speed records.
