Search in various scores for illustrations of punctuation; then write some examples of your own. See the novel use of flutes for punctuation at the very opening of L’Apprenti sorcier by Dukas; the single explosive chord at the beginning of “Ronde du Sabbat” from Symphonie fantastique by Berlioz; and the woodwind sforzando effect at measure 297 in the Symphony No. 8 by Beethoven. It will take some searching to find other examples, but almost any well-written score will make some use of this principle.
