The Hunger Games
In Chapter 26, Katniss deduces some of the layout of the Training Center: "It's a relief to be alone with Cinna, to feel his protective arm around my shoulders as he guides me away from the cameras, down a few passages and to an elevator that leads to the lobby of the Training Center. The hospital then is far underground, even beneath the gym where the tributes practiced tying knots and throwing spears." (p. 352). This also works metaphorically as an indication of the hospital's lesser importance; the Capitol is more concerned with training children to fight each other than with healing them afterwards.
Catching Fire
Near the beginning of Chapter 6, Katniss lists the foods and drinks at the Capitol party: "Countless cheeses, breads, vegetables, sweets, waterfalls of wine, and streams of spirits that flicker with flames" (p. 77). As if to mirror the extravagance of the Capitol, part of her description alliterates: "waterfalls of wine, and streams of spirits that flicker with flames."
Mockingjay
In Chapter 4, Katniss comments on her shoes: "Mine don't fit right anyway, since in the spirit of waste-not-want-not that rules 13, I was issued a pair someone had outgrown. Apparently, one of us walks funny, because they're broken in all wrong." (p. 52). This, too, can be understood more metaphorically as Katniss's not fitting in to District 13. Earlier in the book, she even admits this, although it's just a small example: "once I moved into Compartment 307 with my mother and sister, I was expected to get with the program [the schedules printed on her arm every day]. Except for showing up for meals, though, I pretty much ignore the words on my arm." (p. 18).
