For long Willa Cather＇s pioneer works have gained great critical acclaim and have been interpreted from different perspectives such as mythicism, romanticism, and feminism. This paper, interpreting Willa C ather＇ s classical pioneer works of the three periods from the 1920s to the 1930s-My A ntonia （ 1918）, A Lost Lady （1923）, and ＂Neighbor Rosicky＂ （1930）, is devoted to making a full exploration into the evolution of her ecological thoughts from an ecofeminist perspective. In Willa Cather＇s three pioneer works of different creative stages, she deliberately constructs three eco-worlds as a standard of ecological harmony. In her three eco-worlds, Willa Cather not only investigates the relationship between man and nature, but also involves androcentrism, patriarchy, and other ecofeminist topics. Willa Cather＇s ecological views have undergone changes in her representation of three successive phrases. To interpret Willa Cather＇s pioneer works from the perspective of ecofeminism can provide a deeper comprehension about her works and her ecological thoughts for the world.展开更多

Salinger, occupied the center of many critics after its publication. Holden, as a sixteen-year-old teenager, is full of confusions on the threshold of adult world, and really needs his parents and the society’s guidance but nowhere can he get it; therefore, he gets lost on the threshold of adult world. This thesis tries to analyze Holden Caulfield’s spiritual dilemma based on the theory of American Character developed by David Riesman. America turned into an “other-directed” society after the World War II, which highly advocated personal achievements. Everyone at that time was deeply influenced by that social character. Holden failed to acquire the social character in “other-directed” society in his childhood; consequently, he became the outcast of his society, and stuck in the spiritual dilemma with no way to get out.展开更多

As rigid social connections and concepts restrict women＇s autonomy and freedom, they must transform themselves and the world in order to survive. In order to analyze pioneer women＇s process of self-growth in the special period, the author of this paper compares and contrasts the specific situation, and analyzes the characteristics of the protagonists in the above two novels. Through analysis, the authuor concludes that pioneer women always create a nurturing and gracious atmosphere in their household.

The purpose of the paper is to analyze the protagonists＇ struggle through social restrictions in 0 pioneers？ and My Antonia, so as to analyze the situation pioneer women faced in American mid-west at that age. Women as cultural conservators and transmitters of civilization play integral parts in this respect. It is true that the morality system is set by the patriarchal society and restricts women＇s behavior. However, we must admit that when women stop functioning as civilization transmitters and cultural conservators, the world will go wrong seriously. In the two novels, hearty, generous women always create a nurturing and gracious atmosphere in their household.
