下面我将从以下四个方面阐述我的课：教材分析^p 、学情分析^p 、教学方法、教学步骤和板书设计。

一、教材分析^p ：(教材内容分析^p ，教学目的,教学重点和难点)首先，我来讲下我的教材分析^p 。

这主要包括教材内容分析^p ,学情分析^p ，教学目的和教学重点和难点四个方面。

1.教材内容分析^p这篇阅读材料紧扣本单元的中心话题“野生动物保护的重要性”，讲述了一个叫戴西的小女孩在梦里和一些野生濒临灭绝的动物交谈，知道了保护野生动物的重要性，既是对前面热身部分的升华，也是这单元的主题内容和词汇学习的重点。

这篇文章构造非常明晰，是按戴西在梦中的的三次飞毯经历来分段的，但段落大意不是很明确。

此外，在这篇文章中出现的生词不是很多。

〔下面，我来讲下对学生学情的分析^p 〕2.学情分析^p学生对本单元的主题“野生动物保护”的话题是非常的熟悉，而且学生们对各种各样的动物也非常的感兴趣。

高一现阶段的学生也已经掌握了根本的像寻读，略读，概括等阅读技能，他们也能就一些问题进展英语对话讨论。

但是，学生对文中出现的组织WWF并不清楚，对有些句子所隐含的话外之音也不是很清楚，也对独立解决一些现实的问题感到困难。

3.教学目的本节课的教学目的包括知识目的、语言技能目的、情感目的、文化意识和学习策略目的。

语言技能：1〕学生可以应用不同的阅读技能得到所需的信息；2〕在略读后，学生能概括各段段落大意；3〕学生可以分析^p 作者某些句子的写作意图，像“No rainforest, no animals, no drugs” and “And there are always WWF.”语言知识：1〕学生能知道更多的关于为什么一些动物濒临灭绝以及如何保护它们；2〕通过学习大部分学生可以掌握并运用重要词汇: mercy, importance, contain等等；情感态度：学生可以认识到保护野生动物的重要性；文化意识：学生能对WWF组织有一定的理解。
