Read the quoted parts carefully and answer the questions in English."I celebrate myself, and sing myself,
And what I assume you shall assume,
For every atom belonging to me as good belongs to you.
I loafe and invite my soul,
I lean and loafe at my ease observing a spear of summer grass."
( From Walt Whitman’s Song of Myself)
What does “a spear of summer grass” symbolize?
【正确答案】：

【题目解析】：此诗揭示了“草叶”的意义：自然界最平凡、最普通的草，有广大的生活天地和强劲的生命力量，它"在宽广的地方和狭窄的地方都一样发芽，在黑人和白人中都一样地生长"。惠特曼认为草是他的形象，他的"意向的旗帜，由代表希望的碧绿物质所织成"，他要用“如同草一样朴实”的语言讴歌祖国和人民。在诗人心目中，不朽的草象征不朽的人民，正在发展中的美国、自由和民主的理想。
