there are 3 uses of COMMA WITH PHRASE
1. it can modify a clause without refering to a specific noun in the clause as in the following sentence from gmatprep.
//Because of wireless service costs plummeting in the last year, and as mobile phones are increasingly common, many people now// using their mobile phones to make calls across a wide region at night and on weekends, when numerous wireless companies provide unlimited airtime for a relatively small monthly fee.
With the cost of wireless service plummeting in the last year and mobile phones becoming increasingly common, many people are
"with phrase" DOSE NOT refer to "people"
correct.
make sure you don't think that this is anything "special", though -- this is how prepositional phrases work in general when they are placed in this initial position.
i.e., if you have
prep phrase modifier + , + (main sentence)
... then the prep phrase modifier should describe the whole clause that follows, not just the subject.2, it can mofify a immidiately preceding noun as in the question of this topic.
3, it can modify a clause and refers to a noun in the clause
with good spirit, I learn gmat again. ("with phrase" refers to "I")
3 uses are correct. pls, help, confirm.
this seems accurate.
Hi Ron,
i am confused....
what if these prepositional phrases are not at initial position?
I mean how the placement of the prepositional phrase matters?
can you please clarify the difference of placing prepositional phrase at initial position and later position?
