9. usage of so as to and so that
First, you should know that such + noun + as to is much less common than so + adj/adv + as to.
Now, for the difference between these two. I think these are best illustrated with examples:
Xue Mei spoke in such a way as to calm us down.
The sales materials are presented in such a way as to encourage attendees to purchase the products on the spot.
These usages focus on doing an action and paying to that action while you are doing it so that the action creates
a result. To simplify a bit, these usages answer the question, Why did you do it in that way?
So, the most common words to use with this pattern are way, manner, etc.
Compare these similar sentences:
Xue Mei spoke so that we would stop asking her questions.
The sales materials are presented at the end of the meetings so that the participants won't realize the meeting
is actually a sales presentation.
The part that comes after so... that... answers the question WHY.
I figured out from ur post:
1. "such as N/P to" and "so as Adj/Adv to" are more to less similar.
2. "such as" is less common than "so as"
3. "such as" answers the question "Why did you do it in that way?"
After that I am lost..
Is "so as" is same as "so that" (because u said the "so that" also answers the same question).
....and that post is very informative..
