Book 4 Unit 5 Grammar: Word Formation 梧州八中

关珊珊

指导思想与理论依据：

英语构词法能够帮助学生建立清楚的词类概念，左右相连，形成词汇网；建立词与词的联系，语言能力得到更大发展。本课按照新课标的要求，把语法学习建立在语篇的基础上，在使用语言的过程中进行语法教学。

教学背景分析：

教学内容：

本节课选取的是新人教版教材，必修四，第5单元，语法教学课，内容为构词法。本课时作为本单元的语法教学课，安排在阅读课—“主题公园”这一话题后进行。在上一阶段的阅读课中，学生已经对阅读文章的内容有了深入的理解，有利于学生通过该阅读文章中找出大量的合成词汇，再进一步归纳有关合成、派生（前缀、后缀）等构词法知识，从而帮助学生有效地记忆词汇，了解英语词汇的构成并指导学生通过完成各种学习任务，在真实的情境中学习该语法知识。

学情分析：

本节课的授课对象是高一体育班的学生，基础知识很薄弱，不牢固，，学生很难以初中原有的知识加工新信息。在语言能力方面，学生对于构词法中的“前缀、后缀”等语法概念有所接触和体验，接触到的都是比较零碎的知识，但对本节课的学习还是有一定的铺垫作用。所以在本节课教学中，采取教师引导，学生互助学习的方式。

教学方式和教学手段：交际法、归纳法、任务型活动法

这部分的设计主要选材于课本Reading阅读文章、课本中练习，并结合本节课的教学重难点和目标对教材进行删减和调整，设计了三个主要任务。

①

话题导入：任务相对简单，学生完成度高，可以培养学生的学习信心，提高参与度。

②

发现探索：选材来源于Reading阅读文章，从文章中选取10个单词，这些单词既有合成词，也有非合成词。学生以小组通过观察、分析和研究这些单词在构成上的特点，将词分类

在这一部分中，step1首先给出若干个单词（unhappy, disagree, impolite, misunderstanding, useful, amusement ）让学生判断这些单词是否是合成词，通过让学生寻找所给单词的熟悉部分来凸显前缀和后缀，从而达到引入的目的。

在Step 2中，让学生研究这些单词的构成，并根据这些单词所使用的前缀或后缀在结合意思后进行举例。所给的6个单词中，包含了常用的前缀和后缀，学生在研究的过程中，更系统地学习了常用前缀、后缀的意义和用法。

Step 3教师检验学生的探究结果，并解释前后缀的用法和作用，学生通过老师的解释来验证自己的推断的正确性。除此之外，老师补充一些常见的前后缀,并对这些常见的前后缀的用法进行分类说明，用表格形式展示如下：
