yeap, I scanned that thread yesterday.however, i am still quite confused about the question.
1. i haven't completely understood what did Ron mean by saying “for + verbing” conveys the idea that the action is, in some generic way, oriented toward the process of “verbing”. ".
i think that in the sentence he showed--"i need to get a new pair of shoes for running ",here,the preposition phrase"for running " is used to describe the characteristic of the shoes(more general,i think i may regard it as a noun modifier),because he said"running shoes = shoes whose purpose is oriented toward the general process of running".
and in the sentence"i need to get a new pair of shoes to run",i think i could regard the phrase"to run" as adverbial modifier to describe the whole preceding clause/action, and it delivers the purpose of the action.
so plz point out the mistake i made...
2. the second problem is that Ron said we have to choose "to take charge of" because the action is not an ongoing process...
3.i find what Ron said in the thread you give me about the differences between the "for VERBING" and "to VERB" is different  from what he said in the study hall when he  tries to explain the the "plan for" and "plan to do". I got really confused...

If you pool all the related questions together, you can see that all these questions share the same concept. No disagreement.

-------
on the other hand, the context of OG12 #15 (which i'm not allowed to reproduce here) doesn't work with both expressions.

in that problem, the context is “to take charge of x” vs. “for taking charge of x”.
note that “taking charge of something” is NOT an ongoing process or general procedure -- it's a specific thing, that happens at a specific point in time, and either needs to be done or doesn't need to be done.  it's sort of like succeeding to the presidency, or turning 18, or other such things that happen at a single point in time.
given that context, we must be talking about something that needs to be done -- a remote purpose.  so, in the OG example, you need "to take charge" and not "for taking charge".

-by Ron   http://www.beatthegmat.com/noting-that-the-company-s-network-is-vulnerable-t108143-15.html?sid=06147c953827cefeeb029c35ae0ac108


In the Study Hall, "My plan for making money is to sell my clothes."

"to sell my clothes"    - this is a specific thing, that happens at a specific point in time, and either needs to be done or doesn't need to be done
It's like "to look at the simple problem" - a one-time action
Therefore, we say "to sell my clothes, not "selling my clothes".
Here we say "to take charge", not "for taking charge", because "take charge" is an instant action.


On the other hand,
"my plan for making money" "begin studying the Native American poetry" "begin studying permutation and combination"
These are events that span for some length of time.
(You can simply draw the time axis, and draw the event on the axis. The event is not a time point, but a block on the time axis.)

呵~我本来也是属于始终没弄清to do和for doing的那种，不过看完了Ron的解释，再看baby姐的详细分析之后就好清楚了。不知道zhongshanlh童鞋懂了没？我也来说说我的看法吧。

你问的那个adv. modifer什么的理解着好复杂，按baby姐分析的，其实都是用这两个的意思就解决了。
1、to do是表示“即时的目的”，更像是一种action。Ron举的例子里：
I need to get a new pair of shoes to run.
get a new pair of shoes就是达到to run的直接手段和方法。我穿上新鞋是为了马上就可以跑了。
2、for doing是表示“达到目的的一小步”，更像是一种process。Ron举的例子：
i need to get a new pair of shoes for running.
get a new pair of shoes只不过是我为了running这样一个目标做出的一步，我可能还需要买新衣服，还要吃兴奋剂什么的其他步骤。
