Unit 4 What makes the weather?优秀公开课教案

Unit 4 The world 【主题】The world 【话题】Period 1: The sun

Period 2: The changing weather Period 3: Past and now 【教材及学情分析】

《新世纪英语》五年级第二学期Unit 4教材分为三个主版块，分别为Wonderland版块一些核心词汇shine, earth, comfortable, heat, become, air, raindrop, a kind of。Farmland版块的小对话的核心句型I/You/He/She/We/You/ They did…

I/You/He/She/We/You/They do (does)…主要是进行一般过去时和一般现在时的比较。Grand Theatre版块是一篇科普类文章，关于天气是如何变化和形成的。两个辅助版块是语音版块和儿歌板块。根据单元统整的要求，以“The world”为单元的主题，分别通过三个有关联的话题“The sun”

“The changing weather”“The people”来进行教学，有机地把本单元的核心词汇和核心句型融合在一起，从而提升学生的情感体验，让学生爱大自然，爱身边的事物。

在学生的学情方面，本单元是一个科普类文本的学习，所以学生既要明白科普类知识，还需要学生通过图例用英语来描述科普知识，所以对于学生的要求还是相当高的，特别是在第二教时的文本变化的天气一文中，语言知识点非常多，这就给学生的阅读和理解造成了困难。课堂中主要采用图例和动画，不断描述这些变化的天气，让学生在观看和思考中学会这篇科普文章。此外本单元的核心句型，主要是时态的区别，但部分同学对于这两种时态还是能够区分的。

But in summer it is too hot. We don’t

want to see it. We’d like to have wind and raindrops. What is it? It’s the sun.
