摘要：根据第二语言习得理论(简称SLA),语言输入是语言学习的最基本的条件。正如一个谚语所说,没有语言输入,没有语言习得。作为一种输入技能,在学生的语言学习上，听力有很重要的地位。SLA听力理解是一个重要的学习部分，作为语言输入方法，SLA被公认为最重要的学习方法，SLA听力在语言的学习上得到了越来越多的关注。一个著名教授声称,第二语言教学中认为，听力理解在英语学习的过程中是十分重要的，甚至是最重要的。许多学者因此开始研究哪些因素是影响SLA听力理解的重要因素，但是他们把更多的注意力集中在自学的学习上，而没有考虑到变量之间的交互过程。

there are the findings of learner factors impacting on the SL listening achievement. We can find more information about the direct and indirect impacts on the listening achievement. Researches on listening comprehension’s factors will help to improve the learners’ listening comprehension, which will eventually promote the learners’ language acquisition.

2. An Overview of the Factors Affecting SL Listening Comprehension

Listening is not only an important skill in SL Communication, but also a basic ability in the process ofSLA. It can influence the other SL skills (speaking, reading and writing), and then influence theSLA. In view of the listening as central to the Second Language, it is necessary for us to deepen our understanding.

So we first should understand what SL listening comprehension is and what factors affect second language listening comprehension. This chapter introduces the theory of SL listening comprehension and non-learner factors and learner factors.

2.1. The Definition of Listening Comprehension

Listening comprehension from the theory is viewed as an active process in which individuals focus on selected aspects of aural input, construct meaning from passages, and relate what they hear to existing knowledge.

Anderson[2] divided the listening comprehension process into three stages: the perceptual, parsing, and utilization. On the first stage, listeners usually focus on the oral text and preserve the sound in memory. In the next stage, listeners constructed meaningful mental representations by using words and message. On the last stage, listeners try to link the incoming message to their existing knowledge.

Coakley and Wolin[3] think listening comprehension have five stages. First, learners were motivated to listen to aural input. Second, learners get the messages from the speakers. Third, the information must be attended to short-term memory system. During the stage, learners’ attention also affected by their background knowledge and former experience. Fourth, leaners fitted and attended the information that they received into the appropriate linguistic categories that were stored in the bran. In the final stage, learners responded to the message in the long time memory, then immediate feedback communicated to speakers.

SL listening comprehension is an important part ofSLAand SL teaching. As the second language acquisition theory further development, people come to understand the essence of SL listening comprehension. There are three main methods to the theory of SL listening comprehension: environmentalist approach, innatist approach and interactionlist approach. Environmentalist approach believes that language acquisition d本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
