【正确答案】：
WHITMAN IS RADICALLY INNOVATIVE IN TERMS OF THE FORM OF HIS POETRY.WHAT HE PREFERS FOR HIS NEW SUBJECT AND NEW POETIC FEELINGS IS “FREE VERSE” THAT IS, POETRY WITHOUT A FIXED BEAT OR REGULAR RHYME SCHEME.A LOOSER AND MORE OPEN-ENDED SYNTACTICAL STRUCTURE IS FREQUENTLY FAVORED. LINES AND SENTENCES OF DIFFERENT LENGTHS ARE LEFT LYING SIDE BY SIDE JUST AS THINGS ARE, UNDISTURBED AND SEPARATE. 
【题目解析】：本题考查的是惠特曼在诗歌领域的文学创新性特点。惠特曼在诗歌形式上具有根本的创新性。他对新主题和新诗意的偏好是“自由诗”(Free Verse)，也就是没有固定节奏或规则韵律的诗歌。并且更宽松、更开放的句法结构愈发受到青睐，不同长度的句子并排地书写，但亦不会受干扰而分开。
