How do you comment on Whitman's literary innovation in terms of the form of his poetry?
【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.
