In this article, the author goes into the essence of "restoration", "zerocentigrade writing", "expression of one s emotion in a cool state", explores and analyzes the basic relationship between the poetry subject and the poetry object, and then draw a conclusion that"writing realistically" in the new generation poetry is the same as those in the modernistic poetry rather than in realistic poetry .
如果通过对新生代诗歌所主张的“还原”、“零度写作”、“冷态抒情”等的实质进行挖掘和探究,以及对新生代诗歌中诗歌主体和诗歌对象之间的根本关系进行考察和分析,可以看出:新生代诗歌中的“写实”不是与现实主义而是与现代主义诗歌(比如“朦胧诗”)中的“写实”取着同一精神路向。
