Enlgish Modifiers

I need to pick out the modifiers in each of these sentences. They can either be appostive, resumptive, summative or free. Im having trouble recognizing them and explaining the differences.

Lately I've spent more hours of each week with Gunther than I've spent with my wife, and still there are times - this moment is one of them - when I see him as I saw him the day we met, times when I cannot get beyond the amazing epidermal surface of the man.

His velour pullover is open to his sternum, and the exposed chest is precisely the complexion of new Play-Doh, the substance from which Gunther sometimes seems to be made.

Not because we work in the plants ourselves - our work, like God, is everywhere and nowhere - but because this is where reality is, the life and labor of the folk, the source of all art.

"Yes for a certain number of hours each week we have to do some essentially noncreative work, things that are not really what artists like us should be doing - painting apartments, replacing water heaters, fixing toilets."

I have my job with Gunther - twenty dollars an hour under the table, starting now - and Gunther has his real estate empire, his Ford Bronco, the ability to pay me twenty dollars for each hour I ride around in it with him, and an unflagging, magical belief in the rightness of his life and methods despite all evidence to the contrary.

Gunther loads my arms with equipment from the back of the Bronco - coils of pipe, rolls of solder, garnet paper, a plumber's snake, a portable light, extension cords, a large toolbox.

"I mean a movie that had it all - bar scenes, motorcycle scenes, dressing room scenes, rehearsal scenes, groupie love scenes, and the monster victory-concert scene at the end when the band comes back to its hometown after making it big."

His voice makes me see scenes for a movie version of our horrible century - bombings and occupations, pogroms, refugee camps, a boy in shabby knickers calling out the prices of fruit on the streets of the New World.
