hi -
first off, i wouldn't worry too much about linguistic terms. for gmat purposes, it doesn't terribly matter whether you can get the
name of a modifier correct, as long as you can
use the modifier correctly.
one:
Anon Wrote:E.g the big bird had a wingspan of 12 feet, believed to be X
you wouldn't do this, unless "12 feet" was believed to be something.
here's the best rule to follow:
if a modifier describes a NOUN or noun phrase, then it should be placed directly next to the noun.
this modifier is definitely meant to describe some sort of noun - after all, verbs, adjectives, and adverbs can't be "believed to be" anything - so it should be placed directly next to the noun it's supposed to modify.
if it's supposed to modify "bird" (which seems to be the most logical interpretation, although your example is completely devoid of context), you'd rewrite the sentence in the following way:
the big bird, believed to be X, had a wingspan of 12 feet.two:
Anon Wrote:The old firefighter stood over the smoking ruins, having worked all day
now this is a special type of case.
if you have a participial modifier that describes
an action that has already taken place before the action in the main clause, then that temporal primacy normally causes the modifier to be placed
in front of the main clause. so you'd probably see this sentence written as something like
having worked all day, the firefighter stood over the smoking ruins.
by contrast, if the participial modifier describes a
consequence of the action in the main clause, then it should be placed
after the main clause:
jerry hit three more home runs on sunday, bringing his total for the season to 34.
finally, if the modifier is
simultaneous with the action in the main clause, then it can legitimately be placed either before or after the main clause:
raising his arms in victory, jimmy strode across the finish line a full second ahead of the second-place finisher.
jimmy strode across the finish line a full second ahead of the second-place finisher, raising his arms in victory.
make sense?
