【Abstract】With the increasingly emphasizing on psychology and the thriving of second language acquisition，there is a growing understanding of the importance of affective factors in second language learning. As a fundamental role in human life， emotion play a significant role in second language learning. It has been thoroughly clarified by theories that language teaching should focus on students’ all round development， which means to integrate their cognitive and affective elements. In fact， however， there are increasing number of students and teachers who focus on the effect of cognition instead of that of affect， which might contribute partly to passable English teaching and learning effect. Based on Krashen’s affective filter theory， this paper attempts to analyse the current situational problems of Chinses language teaching so as to enhance the foreign language teaching level.

　　1. The definition and importance of affective filter theory
　　To establish the importance of affective factors in second language learning， it is necessary to introduce definition of affective filter theory. For the purpose of reducing learners’ negative emotion and fear of difficulties， Stephen Krashen （1982）， an excellent professor at University of Southern California indicates that， language teachers should create a more relaxing and effective teaching environment， where students can correct mentalities and build self-confidence for language learning. In the affective filter theory， Krashen regards the negative emotion as a filter which impedes the input that learners can understand between the teachers and learners.
　　It is thought that， the affective filter may have been an important factor in second language acquisition. Many researchers has stressed the importance of affective filter thesis. For example， Arag?o （2011） explains the significance of affective filter thesis with two reasons. Firstly， the emotion statement is one part of normal activities that cannot be ignored. Secondly， affective factors may contribute to both language learning and language teaching， which seem to decide the comprehensive development of students. The next chapter described Chinese current educational situation and reasons why that happened. 　　2. The current Chinese educational situation
　　As increasing attention attached to education of next generation， the Chinese educational situation improved in an certain degree. However， the excessive emphasis on students’ academic record and the pursuit of speed-up educational programs， have led to both ignorance of student’s mental state and backwardness of language teaching. The foreign language teaching in China is mainly based on classroom teaching， which means the teacher play a relatively important role in classrooms who shoulder responsibility of imparting facts and theories as well as solving puzzles， while the students are just passive receivers. Therefore， students rarely have opportunities to put it into practice， even if they do， they almost imitate to make sentences mechanically. Such teaching philosophy and learning methods will inevitably lead to students’ high scores on exams and low abilities in practice. On the whole， the current situation of language education has problems related to both students’ psychological state and teachers’ teaching philosophy. Therefore， several factors are known to be partially responsible for this.
　　The most likely cause of that might be current Chinese educational system. For the past few decades， under the influence of the college entrance examination system， a system that means the chance of stepping into excellent universities for students measured by their college entrance examination achievement. Therefore， to help students embrace promising futures， most schools try their best to raise students’ level of learning achievements instead of their mental development， which is particular in language teaching. In one world， the current examination system has negative effect on foreign language learning to some extent.
　　Another reason which causes the present situation of language teaching is the defects of teaching philosophy. Teachers’ teaching philosophy is a foundation of class which has effect on students’ understanding （Betty， Lein
