英语选修8人教版新课标Unit 2阅读教案Unit 2 Cloning: Where isit leading us?中国书法艺术说课教案今天我要说课的题目是中国书法艺术，下面我将从教材分析、教学方法、教学过程、课堂评价四个方面对这堂课进行设计。
一、教材分析：本节课讲的是中国书法艺术主要是为了提高学生对书法基础知识的掌握，让学生开始对书法的入门学习有一定了解。
书法作为中国特有的一门线条艺术，在书写中与笔、墨、纸、砚相得益彰，是中国人民勤劳智慧的结晶，是举世公认的艺术奇葩。
早在5000年以前的甲骨文就初露端倪，书法从文字产生到形成文字的书写体系，几经变革创造了多种体式的书写艺术。
1、教学目标：使学生了解书法的发展史概况和特点及书法的总体情况，通过分析代表作品，获得如何欣赏书法作品的知识，并能作简单的书法练习。
2、教学重点与难点：（一）教学重点了解中国书法的基础知识，掌握其基本特点，进行大量的书法练习。
（二）教学难点：如何感受、认识书法作品中的线条美、结构美、气韵美。
3、教具准备：粉笔，钢笔，书写纸等。
4、课时：一课时二、教学方法：要让学生在教学过程中有所收获，并达到一定的教学目标，在本节课的教学中，我将采用欣赏法、讲授法、练习法来设计本节课。
（1）欣赏法：通过幻灯片让学生欣赏大量优秀的书法作品，使学生对书法产生浓厚的兴趣。
（2）讲授法：讲解书法文字的发展简史，和形式特征，让学生对书法作进一步的了解和认识，通过对书法理论的了解，更深刻的认识书法，从而为以后的书法练习作重要铺垫！（3）练习法：为了使学生充分了解、认识书法名家名作的书法功底和技巧，请学生进行局部临摹练习。
三、教学过程：（一）组织教学让学生准备好上课用的工具，如钢笔，书与纸等;做好上课准备，以便在以下的教学过程中有一个良好的学习气氛。
（二）引入新课，通过对上节课所学知识的总结，让学生认识到学习书法的意义和重要性！（三）讲授新课1、在讲授新课之前，通过大量幻灯片让学生欣赏一些优秀的书法作品，使学生对书法产生浓厚的兴趣。

人教高中英语选修八Unit2-Cloning教学设计
Unit2 CloningReading: CLONING: WHERE IS IT LEADING US? 教学设计一、教材分析本单元以Cloning为话题，旨在通过单元教学，使学生了解克隆技术的优缺点，学会表达和支持个人观点，能用所学的有关Cloning的词汇去表述自己对这一新技术的观点和看法。
”阅读”（Reading）部分提供的材料CLONING: WHERE IS IT LEADING US?是一篇介绍克隆技术的说明文, 具体介绍了植物与动物克隆的区别，多利羊的诞生与死亡及由此引发的争论。
帮助学生进一步认识克隆的意义在于解决医学上的难题，为人类服务。
从话题内容上分析，Warming Up 与Reading相一致，从教材份量来说，可将Warming Up和Reading整合在一起，设计成一节任务型“阅读课（精读课）”。
二、学情分析我所带的两个班级的学生英语基础一般，平时较少阅读科学题材的文章, 知识面相对狭窄，阅读理解这篇文章还是有一定难度。
但学生的好奇心和学习接受能力比较强，可以布置学生课前上网或去图书馆找出一些有关克隆的资料，并与多媒体相结合简单介绍克隆及克隆技术的一些知识，让学生有了一定的知识准备以利于很好的理解课文。
三、设计理念及教学目标这节课的主要目的是培养学生跳读和细读的阅读技巧，使学生学会准确分析阅读问题，懂得从文章中找到关键句子摄取必要的信息，找出正确的答案。
我运用多媒体和学生搜索材料主动参与学习相结合，设计了表格、问答题、判断题和信息整理题。
这不仅提高学生的阅读技巧，也教会学生怎样处理不同的阅读问题。
四.教学目标Teaching goals1. Target language目标语言a. 重点词汇和短语clone，commercial，producer，undertake，arbitrary，object，forbid，ac cumulate，cast down，object to，the media，in favor ofb. 重点句子It is a way of….The fact is that….The question that concerned all scientists were: ….2.
