✿哈尔滨市呼兰区利民中学 杜亚辉

（本课选自义务教育课程标准实验教科书仁爱版《英语》八年级上册第4单元第一话题。）

●教材分析：

本单元的3个话题紧紧围绕当今世界环境、科技和文化这三大主题展开。

第一部分是让学生学习如何用英语描述和谈论我们生存的自然环境，形容词的比较级和最高级的运用是这一部分的重点语法项目。本话题主要通过谈论和描述自然界的风光、动植物及生存资源——森林和水，引入本单元主要语法项目。如果抓住这个话题，设计一些丰富的教学活动，既可以综合练习所学知识，还能培养学生合作精神及创新思维。

●教学目标：

1.知识目标：掌握形容词比较级和最高级的变化规则及用法。用英语谈论自然界中的动、植物，让学生初步了解它们之间的关系。

2.能力目标：能使用一些简单的英语语句描述和谈论自然界动物和植物之间的关系。能听懂简单的故事，理解其中的主要人物和事件，能在教师的指导下参与角色表演等活动，能将所学语言组织起来，写出简短的文章。

3.情感目标：通过对自然界的认识，培养学生热爱自然、保护环境的美好情感，同时提高学生的交际能力和与他人合作的能力。

●教学重难点：

1.教学重点：通过谈论自然界中的动植物，学生能用英语与他人谈论我们生存的自然环境，而且能熟练运用形容词的比较级和最高级，能与学生就形容词的级别这个话题交换信息，使学生具有积极参与课堂上各种英语实践活动的兴趣。

2.教学难点：用所学知识会话，写出简短的文章。

●教学设计：
