In The Hunger Games, explain the irony of the image of Katniss as she "peers through the trees, past the fence, into the meadow."

I am having difficulty tracking down your exact quote, but
I wonder if you are not refering to the moment in chapter two when Katnis volunteers to
replace her sister as the female competitor for the Hunger Games. Note what the text
tells us after Katniss goes up to the stage to receive the dubious
honour:

I put
my hands behind my back and stare into the distance. I can see the hills I climbed this
morning with Gale. For a moment, I yearn for something... the idea of us leaving the
district... making our way into the
woods...

The irony of this
passage lies in the fact that that very morning, Gale had suggested to Katniss that they
lived together in the freedom of the woods to escape the tyranny of their lives.
However, of course, now it is too late as Katniss will represent District Twelve and
there is no escape. I hope this relates to the quote you meant. If you can tell me in
which chapter it is, I might be able to respond more precisely, but I think it probably
relates to the irony I have explained.
