Hello,
So I know how the VERB-ing and Verb-ed modifiers work, and then read on a supposedly respected test prep company blog something which is a turnaround from what I know. :(
If it's ok, I would like to summarize everything here; all I would request is a perusal to state that it is all OK.
VERB-ING: Without Comma
Those are my balls rolling down the aisle.
Structure: Clause- Verb+ing
What it modifies : The immediate preceding noun.
VERB-ING:With Comma
These balls are still on the table,defying gravity.
Structure: Comma+ Verb-ing
What it modifies : The result of the preceding clause/The action of the previous clause.
VERB-ED:Without Comma
Those are my balls destroyed by the thunder.
Structure: Clause+Verb-ed
What it modifies : The immediate preceding noun.
VERB-ED:With Comma
Those are my balls in the courtyard,destroyed by the thunder.
Structure: Comma+Verb-ed
What it modifies : The subject in the preceding clause.
I apologise again if any of this is not correct. It's too darn confusing now.
