a problem about how to review present participle, etc

[saintjingjing]

en, thanks in advance.

I am confused about the usage of no comma +present participle, comma+ present participle.

I do not know how to understand these points.

For example, from OG12-105#, og once said that coordinating can not modify illustration( sorry, I do write here), but from M-SC book, comma+participle (like coordinating) can not modify the noun. it only can modify verb.
But OG is correct. I can not opposite it.
But I think points from comma+ participle from Manhattan-sc book are also correct.
But these points are conflict.

So, I want to ask what is the usage of comma+participle and no comma+ participle

sorry, initially, many confused parts here. I am confused about the OE from OG. In my eyes, these are contradictory

I am really sorry to have to say this, but there are so many grammar and construction errors in your post I'm not really sure what you're asking. Can you try again and be very careful and clear about what your sentences are saying and what you're asking? Reviewing your own writing for errors is a good way to start the process of identifying errors in SC problems..

I rewrite.

The OG answer is correct, but their explanations often leave a lot to be desired. In particular, their treatment of the modifier issue here is a little unclear. Go with what's in our book..
