Learning about Language全国优秀课堂实录

Unit 2

Working the land

I．教学内容分析

本单元以“农业”为中心话题，涉及了农村、农业产量、我国著名的杂交水稻专家袁隆平和有机农业等一些问题。

Warming Up部分通过3个问题和两幅图，使学生达到热身的效果。有些学生有过在农村生活经历，让他们简短地讲出来，与其他同学一起分享，一起了解一些有关农业的知识。因为这部分的问题，对于农村的孩子，他们有生活，就有话说；对于城市里的孩子来说，有新鲜感，所以能比较容易调动起学生的积极性。

Pre-reading部分以水稻这种农作物为主设计了三个问题，这三个递进式问题的设计，力图激发学生已有的知识和经验，发挥学生的想象力来更好地理解课文。另外，还可以激发学生的同情心和人道主义精神。

Reading部分是对一位伟大的科学家——“杂交水稻之父”袁隆平的介绍。本文通过介绍他的家庭背景、学业、科研成就、无私品质、和普通人一样的生活，使一位普通、朴实又务实的中国农业科学家形象活生生地展现在学生面前。

Comprehending部分设置了四个练习，主要用来帮助学生更好地理解阅读课文的内容。

Learning about Language部分帮助理解本单元重点词汇和语法。本单元的语法是动词-ing形式作主语和宾语。

Using Language部分综合训练学生的听说读写能力。本部分紧扣本单元的话题，讲到了什么是有机农业、有机农业的好处和有机农业在农作物种类选择方面的具体做法。其中写作部分使学生复习了如何表达建议并学习怎样用英语设计食品小广告，突出了实用性。

Summing Up部分让学生对本单元所学的知识进行归纳。

Learning Tip指导学生在写作或会话过程中记笔记，使学生讲话或写作时条理清晰，层次分明。
