Song of Myself (自我之歌) --------Walt Whitman (realism)
I celebrate myself and sing myself,  (Self includes everything and everyone in the universe)
And what I assume you shall assume, (I and you stands for new Americans with democratic ideas and American spirit. the nature)
For every atom belonging to me as good belongs to you. (embody the unity of you and I  it emphasize the closely connection of you and I)
I loafe and invite my soul(Loafe: =loaf  闲逛Emphasize the unity of body and soul)
I learn and loafe at my ease observing a spear of summer grass. (Grass stands for ideal, hope, it can grow at different space, so it stands for development especial the development of human) 
我赞美我自己,歌唱我自己,
我所讲的一切,将对你们也一样适合,
因为属于我的每一个原子,也同样属于你。
我闲游,邀请我的灵魂一起,
我俯首下视,悠闲地观察一片夏天的草叶。
My tongue every atom of my blood form‘d from this soil this air
Born ere of parents born here from parents the same and their parents the same
I now thirty seven years old in perfect health begin
Hoping to cease not till death.
Creeds and schools in abeyance,(a state of disuse or suspension  归属待定    尤未定夺)
Retiring back a while sufficed at what they are but never forgotten.
I harbor (怀有) for good or bad I permit to speak at every hazard. 随便地,
Nature without check with(与.相符)original energy.
我的舌,我的血液中的每个原子,都是由这泥土这空气构成,
我生在这里,我的父母生在这里,他们的父母也生在这里,
我如今三十七岁,身体完全健康,开始歌唱,
希望不停地唱下去,直到死亡。
教条和学派先不去管,
暂且退回来,满足于它们的现状,可是决不能忘了,
我一味怀抱自然,我允许无所顾忌的诉说自然,
以原始的活力,谁也不能阻挡。
"Song of Myself" is a poem by Walt Whitman that is included in his work Leaves of Grass. It has been credited as "representing the core of Whitman’s poetic vision."
Free verse 自由诗体 Combination of biography, sermon, and poetic meditation
The two principal beliefs embodied in this poem:
    In this poem Whitman sets forth two principal beliefs: the theory of universality, which is illustrated by lengthy catalogues of people and things, and the belief in the singularity and equality of all beings in value. He extols whole universe and the world. He is thinking of the self as a powerful and sensitive instrument for receiving and expressing. He moves from himself to you to others, to all humanity all together about him.
Walt Whitman hoped that his poem would reunite America, thereby avoiding the civil war.
Literary styles of Song of Myself
The poem is written in Whitman's signature free verse style. Whitman, who praises words "as simple as grass" (section 39) forgoes standard verse and stanza patterns in favor of a simple, legible style that can appeal to a mass audience.
Critics have noted a strong Transcendentalist influence on the poem.
In addition to this romanticism, the poem seems to anticipate a kind of realism that would only become important in United States literature after the American Civil War.
Self
In the poem, Whitman emphasizes an all-powerful "I" which serves as narrator, who should not be limited to or confused with the person of the historical Walt Whitman. The persona described has transcended the conventional boundaries of self:
Whitman does not consider the narrator to represent a single individual.
Form
poetry without fixed beat or regular rhyme.  Free verse                 
songWhitman is the first great American poet to use this form of poetry, he also used it more skillfully than any other poet.
he broke the conventional poetic materials, no myth, no romance, no story of king and lords. He sings for self, common people, America, city life, nature, etc.
Theme:
  Whitman sings of nationalism and of the nature of the self in relation to the cosmos and the meaning and purpose of birth and death. Individualism, nationalism, and internationalism or cosmopolitanism, the three contradicting beliefs are reasonably united.
    song of Myself was the concentration of Leaves of Grass, confirming its epic aspect and Whitman’s unique perspective and unusual artistic composition. Fundamentally, Song of Myself is a song of freedom, democracy, equality and love. It shows poet’s philosophical and religious thinking of life and cosmic inventory
