First, it shows that the overall narration of the novel is existential. Second, from the perspective of Sartrean love, it tries to analyze the love between Jake and Brett. Third, it analyzes the technique “existence precedes essence” in depiction of the characters in The Sun Also Rises. Finally, it analyzes that most of the choices of the heroes and heroines are irrational but they accept the results of the choices in the rational way.

It puts great emphasis on making the students learn in a relaxing atmosphere, and people pay more and more attention to the English education environment. Therefore, English education for children should give up the traditional educational model, and explore a set model to suit the children’s development that combines children’s psychological and physiological feature. Up to now, English teaching has made considerable progress in China; a number of children English teaching methods have come into being. TPR teaching method is regarded as one of the popular children English teaching common methods. The paper aims to prove that TPR teaching method is suitable for children English teaching. It will introduce the method of Total Physical Response first, and then illustrate the effect of Total Physical Response teaching approach on little kids in the kindergarten. It explains the theoretical basis of TPR and analyzes the advantage and function of TPR in Children English teaching. It also discusses the concrete training in stimulating and improving young EFL learners’ learning interest combining with some activities. Finally it mentions some emerged misunderstanding and some problems to be paid attention to in the field.
