Abstract: Analyzing the historical background and theoretical basis of the post modernism law, this paper points out the main theoretical standpoints and give the reasonable comment on the post-modernism law.

Along with gradually penetrating of Western Modernism Literature, many forerunners accepted this theory and made it instructe their creation, thus broke the forbidden region of tranditional produce.

In the hundred-year history of western modernism literature,the writers invention is always accompanied by fantastic experience,which is the perception of human beings for their living conditions,and becomes stronger and stronger with the materialization of man.

Thus it becomes a central motif of modernism literature to probe into human beings spiritual Eden.

Rules of the game of postmodern literature have abandoned the writing rule of realistic and modern literature.

In the canon of western modernist literature there are quite a lot of body narratives,in which four types of human body can be identified: the hurt body,the sick body,the body of prostitute,and the idealized female body.

Studying modernist literature from the perspective of modernity of post-modernism,researchers can find four intercontacted and interacted poetical features:the experimentality,introversion and abstractness of style,and the intransparency of text.
