教学设计2：Unit 2 Working the land
Unit 2 Working the land 一、课标内容二、教学要求(Teaching demands)三、教学建议(Suggested teaching notes)1、课时分配用6个课时完成教材内容，仅作参考。
2、教材各部分教学建议本单元的中心话题是“农业”。
“热身”（Warming Up）部分围绕有关农业、农村和农作物种植的内容提问，让学生谈谈对农村和农业劳动的认识或经验。
采用讨论法，在讨论中，教师可充分调动来自农村的学生的讨论积极性，并给予学生一个互相学习和交流的机会。
对于没有这方面知识和体验的学生，教师应鼓励他们利用这一机会进行社会调查，有条件的最好能到农村体验生活，让学生有机会真正了解农村生活，了解中国农民的生活现状，提高他们对农业的认识，使来自城镇的现代农业知识的中学生对农村和农业有一定感性认识。
“读前”（Pre-reading）部分提了两组问题。
第一组问题讨论大米在东亚和东南亚国家的人民基本生活中所处的地位；第二组问题提出了世界上迫切要解决的现象即饥饿。
有关讨论不仅力图激发学生的创造性思维，帮助对课文的理解，为阅读部分的教学做好铺垫。
同时让学生了解世界上还存在极其严重的饥饿问题，培养了学生的同情心和人道主义精神。
“阅读”（Reading）部分介绍中国著名的农业科学家、“水稻之父”袁隆平和他的巨大成就。
第一段通过对袁隆平的外貌描写，刻画出一个普通中国农民的形象。
袁隆平也称他自己是农民，也和农民一起耕种，他的科研殿堂就是广阔的农村。
然后介绍袁隆平的科研成果—超级杂交水稻。
第二段介绍袁隆平的家庭背景、学业和科研情况。
第三段勾勒出袁博士不图名不图利，无私奉献的高尚品质。
教学中我们可以引导学生从不同角度分析袁隆平的工作、成就、生活及人格魅力等，勾画出一个过着普通人的生活，干着伟大的事业人先进人物；塑造了一个朴实、务实的中国农业科学家的形象。
“理解”（Comprehending）部分设计了三个练习。
