　　Introduction
　　J.D.Salinger are considered by many critics and readers to be one of the most significant and influential American writers after World War Two.In 1951，the publishment of his only long novel The Catcher in the Rye made him famous across the nation.
　　Id seeks to satisfy the needs of instincts while the superego acclaims the rules of behaving the self morally despite whatever difficulty from the id.The ego isobligatory to settle any problem arsing from between the id and superego.The ego is required to satisfy the needs of id，but not at the expense of the superego.Holden's ego failed to offer a resolution for the conflicts between the id and superego because of his long-term depression from the power of id and loss of superego.Thus，the superego and id together accounted for the imbalance of ego.
　　Holden’s Id
　　The id is comprised of instincts and impulses. Freud upholds the belief that all human behaviors are originated from libido whose nature is impulse.Human beings are driven by the power of libido in their pursuit of dreams and they fight against what is getting in the way to achieve what they want because of libido.
　　Holden’sSexual Repression
　　The pressure of adolescent sexuality， an important theme throughout The Catcher in the Rye， makes itself felt here for the first time： Holden’s greatest worry is that Stradlater will make sexual advances toward Jane， a girl Holden seems to care for very deeply， who hangs out with Stradlater.
