摘 要

在英语学习中，语法学习往往在传统教学中一带而过。然而，语法是非常重要的。掌握好语法是提高英语水平的必要条件。输入假说作为较有影响力的第二语言习得的理论之一，在现代教学中得到了广泛的应用。在输入假说的指导下，听力和阅读教学探索出了一种新的教学模式，并取得了显著的效果。因此，受到广大学者的启发，本文从前人很少有研究的语法角度探讨了输入假说的应用，希望能为语法教学提供启示。

本文以9年级两个平行班的103名学生作为研究对象。两个班分别为实验班和控制班。实验班采用输入假说指导下的新教学方法，控制班则采用传统的教学方法。在为期4个月的实验前后对学生进行测试。实验数据用SPSS软件进行分析。研究表 明，实验班在测试中得分明显高于对照组，所以可以得出结论，基于输入假说指导下的语法教学方法比传统的语法教学方法更有利于提高学生的语法学习能力。

Chapter Ⅰ Introduction

The informationization of social life and the globalization of economy make English more and more important. As one of the most important information carriers of human beings, English has become the most widely used language in human life. Compared with practicing spoken English and memorizing words, grammar seems to have been neglected. But the actual reality is the opposite, grammar is of great importance.

• 1. Research Background

In middle school English teaching, grammar learning is interspersed with text learning instead of setting up separate grammar lessons. It can be seen that grammar learning has received little attention. Therefore, how to implement grammar teaching effectively in middle school classes and how to develop students#39; grammar skills are the current problems. At present, the grammar teaching in middle school is not optimistic. The main problems are the single implementation approach, the lack of extension content and the shortage of teaching practice. More problems are as follows. Due to the heavy course content and tight course schedule, many teachers have adopted the teaching form of direct translation. This method places too much emphasis on the form of language without paying enough attention to the meaning of language. In such a classroom atmosphere, students#39; study enthusiasm is not high and teachers also feel bored not to mention the teaching effects.

Many scholars try to use new teaching methods to teach grammar, such as task-based approach and communicative approach. Krashenrsquo;s Input Hypothesis has also gained a lot of attention. Many scholars have applied Krashenrsquo;s Input Hypothesis to listening teaching and writing teaching and achieved some results. To sum up, can Input Hypothesis also be used in grammar teaching and learning? This paper mainly focuses on this issue.

• 1. Research Questions

This paper focuses on the following questions:

1. Can the new teaching approach improve students#39; grammar ability through a large amount of comprehensible grammar input?
2. Is it helpful to enhance studentsrsquo; interests by class activities?
   1. Research Significance

Language learning requires a lot of input and only effective input can achieve the maximum input effect. Finding the best input timing, giving students an appropriate amount of comprehensible input, and paying attention to the order and sequence of input are exactly what the Krashenrsquo;s Input Hypothesis emphasizes. Therefore, the significance of this research lies in the exploration of the application of Krashenrsquo;s Input Hypothesis in grammar teaching in middle school, which can provide suggestions for further grammar teaching.

• 1. Thesis Framework

This paper is divided into five parts. The first part mainly introduces the research background, research problems and research significance. The second part is a literature review, expounding the Second Language Acquisition Theory and Input Hypothesis proposed by Krashen, as well as the research status of relevant topics at home and abroad. The third part is the experimental design. This part expounds research objectives and research methods and introduces the whole process in detail. The fourth part displays and analyzes the data. The fifth part summarizes the thesis and concludes the limitations of the experiment and provides suggestions for grammar teaching in middle school.
