sprachliche Mittel heraussuchen

Hallo,
Ich hoffe jemand kann mir helfen.
Und zwar soll ich aus folgenden drei Sätzen ( Martin Luther King Rede ) sprachliche Mittel heraussuchen und diese dann erläutern. Es reicht mir völlig aus, wenn jemand die sprachlichen Mittel
herausschreibt ohne Erläuterung, dass mach ich schon selber.

I have a dream that one day on the red hills of Georgia, sons of former slaves and sons of former slave-owners will be able to sit down together at the table of brotherhood.

I have a dream that one day, even the state of Mississippi, a state sweltering with the heat of injustice, sweltering with the heat of oppression, will be transformed into an oasis of freedom and justice.

I have a dream my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character. I have a dream today!
