人教版英语必修三Unit 4(第一课时)教案
Unit 4 How Life Began on the Earth人教版高一英语必修三第四单元第一课时一教学课型阅读课二教材分析这节课内容的中心话题是“天文学”。
这篇文章是一篇夹叙夹议的说明文。
讲述了地球上生命的起源，先从“宇宙大爆炸”讲起，具体介绍了各种生物的起源和出现的顺序。
文章脉络清晰，结构分明，“生命起源”这一话题对高中学生来说充满了趣味性，引人入胜，给学生留下很大的思考空间，能够激发学生的想象力，积极去阅读文章，了解生命的起源以及生物进化的过程。
接着文章就人类对地球的负面影响和地球是否能延续进行讨论。
学生通过略读、速读、摘记等，根据各环节设计的具体任务来学习理解这篇文章，帮助学生进一步了解保护地球的重要性。
通过任务型教学，促进学生进行小组合作学习。
三学情分析高一年级的同学经过上一学期的学习，对于高中学习方式以及培养的能力都有了一定的认识。
在阅读技巧方面，大都学生已经掌握了如略读、跳读、细读等阅读技巧，能在短时间内找到关键词和关键句；但是由于基础不一样，并且地球起源这个话题对于大部分学生来说是陌生的，特别是对于初中基础差暂时落后的学生，所以这也要求我们在设计学案的时候要难度设计要层层递进，区别对待基础不同的学生。
四教学目标 1 知识目标：通过阅读学习，使学生能读懂文章内容，理清文章脉络，让学生了解地球生命的由来以及生命进化的过程 2 能力目标：通过略读、速读、摘记等培养学生的文本解读能力帮助学生形成有效学习策略，提高自主阅读的能力；在质疑，小组探究，同伴互助学习过程中，培养学生独立思考，推理，判断和创造性思维的能力和合作学习策略。
3 情感目标：通过对文章的学习及课堂活动参与激发学习热情，产生学习英语的浓厚兴趣；了解地球上生命的起源及其发展过程，并学会用科学的眼光看待事物，激发学生探索科学的热情。
引起他们对地球未来的关注，对地球面临危机的思考，意识到爱护地球，关爱生命的重要性。
五教学重点难点1. 让学生了解地球生命进化的历程，培养学生获取，分析和处理信息的能力。
