教学设计、课堂实录及教案：人教版高中英语选修八Book8 unit2 Cloning Using Language II内蒙古省级优课
教学设计 人教2003课标版 选修8 Unit2 Cloning Using Language II
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。我要讲的是Using Language “语言运用”部分的第二部分Listening and Speaking 听说部分。这部分先让学生听完一段关于克隆是否对动物残忍的对话后，首先交流听力内容,然后展开讨论，让学生发表自己的看法。这项练习不但有利于提高学生的听说能力，而且还能引发他们的思考，具有现实意义。 学情分析：
我所带的班级的学生英语基础不错，学生的好奇心和学习接受能力比较强。此外，在近两年的英语教学中师生之间配合越来越默契 学生养成良好的听力和讨论习惯，所以本堂课可以充分发挥学生自主性，把课堂大胆的还给学生，他们一定会给我们带来惊喜的。

Science and technology is a double-edged sword, so is cloning. It can bring us benefits and disaster as well. There is no doubt that cloning is a great achievement, but we have to be rational to use it. We can apply it to our medical system, clone organs to replace the bad ones, and do some experiments on animals. However, I strongly oppose to cloning human.Clones have no parents, but they have their own thoughts, because of it, the world will probably be in a mess.
Step V . My view :
Take the advantages and be responsible!

The students are interested in this topic and they are actively involved in the group discussion. What surprised me most is their performance in the debate . Their language is well organized and they are quite logical. Give students more chances and they may work wonders!
