摘 要
   
乔姆斯基提出的普遍语法是现代语言学中非常重要的一个理论，具有较强的解释力，能够解释行为主义者无法回答的语言习得中的逻辑问题。它最初是针对母语习得提出来的，目前越来越多被用于二语习得的研究。关于普遍语法对二语习得的可及性问题存在不同观点。笔者认为，普遍语法对二语习得，尤其是小学低年级学生的二语习得是可及的。近年来，普遍语法在我国的二语习得中的应用研究得到突飞猛进的发展。本文首先简要介绍普遍语法原则和参数原理，然后结合小学低年级学生学习英语的特点，总结出普遍语法对小学低年级学生英语教学的启示。研究过程中，笔者对附近多所小学英语教师进行了问卷调查。调查发现，低年级学生（1）已基本掌握了汉语语法；（2）接触到较有限的英语输入；（3）注意力时间短；（4）不太注重英语语法。基于此，笔者得到了如下启示：（1）英语教学中适量使用汉语并应用对比分析促进英语学习；（2）加大英语输入量和练习量；（3）缩短课程时间并加大活动量（4）适当注意借助中文讲解。

ABSTRACT
   
Universal Grammar is a very significant theory in modern linguistics. Universal Grammar is persuasive in that it in a way serves as an answer to the logical problem of language acquisition that traditional behaviorists fail to answer. Universal Grammar is applied to the research of second language acquisition nowadays while it is primarily put forward to deal with first language acquisition. Although views vary on the availability of universal grammar for second language acquisition, it is believed that universal grammar is available, especially for lower grades pupils. In recent years, Universal Grammar made considerable strides in the applied research of second language acquisition in China. This paper begins with the introduction of principle and parameters theory of UG and then it explores the features of English learning for Chinese lower grades students. Hence, implications of English teaching for lower grades students are concluded based on that. During the research process, survey is carried out among teachers of lower grades students in nearby schools. The results revealed that lower grades pupils (1) have a sound grasp of Chinese;(2) have a limited input of English;(3)have a much shorter attention span;(4)pay less attention to grammaticality. Based on that, implications on teaching English could be made which include (1)to use Chinese appropriately and apply contrast analysis to promote English learning;(2)to increase the input of English and advance practice;(3)to shorten the class duration and organize more activities;(4)to pay more attention to apply Chinese to the explanation of English grammar.
