Abstract:

Interlanguage fossilization is an important theory in the study of foreign language acquisition. In the process of the second language acquisition, learners use certain learning strategies to form the dynamic system of language, which is different from its mother language and the target one. With the progress of the study, it can gradually transit to the target language, while some grammar rules and pronunciations, existing in the dynamic system of language, are not easy to change. This article, based on the interlanguage fossilization research overview, explores the reasons of the phenomenon, and puts forward some suggestions on preventing fossilization.

摘要：

中介语石化现象是外语习得研究的一项重要理论。 它是指在第二语言习得过程中，学习者通过一定的学习策略，在目的语输入的基础上形成的一种既不同于其第一语言，也不同于目的语，但是随着学习的进展向目的语逐渐过渡的动态的语言系统，而某些非目的语的语法，语音等长期存在于中介语中，并且不易改变。本文在概述中介语石化研究基础上，研究其分析方法，探讨其产生的原因，并提出防止石化的一些观点和建议。

1. Introduction
Interlanguage fossilization has received extensive attention from foreign language researchers for a long time. From the surface of language, it is not in conformity with the rules of the target language. According to the theory of language acquisition analysis, it is inevitable in language learning.
Interlanguage fossilization research has achieved representative results since the 1970s.  In 1972，American linguist Selinker put forward the interlanguage hypothesis in his famous paper The Interlanguage. It suggests that learners always use a kind of interlanguage when learning a foreign language and defined as systematic knowledge of language that is independent of both the learner’ system. The hypothesis is an attempt to explore the acquisition of language system and the rule in the process of second language acquisition. In 2003, Ellis put forward the internal cause and external cause of interlanguage fossilization in The Second Language Acquisition and Language Declaration. William Littlewood (England) divided the fossilization into individual and community fossilization according to the characters of the immigrants’ dialect in 1984. He believes that the individual fossilization is earlier than community fossilization, and individual fossilization belongs to the community fossilization. These expressions laid a theoretical basis on the roll of interlanguage fossilization in second language learning.
