教學設計、課堂實錄及教案：人教版高中英語選修八Book8 unit2 Cloning Using Language II內蒙古省級優課
教學設計 人教2003課標版 選修8 Unit2 Cloning Using Language II
教材分析：
本單元以Cloning為話題，旨在通過單元教學，使學生了解克隆技術的優缺點，學會表達和支持個人觀點，能用所學的有關Cloning的詞匯去表述自己對這一新技術的觀點和看法。我要講的是Using Language “語言運用”部分的第二部分Listening and Speaking 聽說部分。這部分先讓學生聽完一段關于克隆是否對動物殘忍的對話后，首先交流聽力內容,然后展開討論，讓學生發表自己的看法。這項練習不但有利于提高學生的聽說能力，而且還能引發他們的思考，具有現實意義。 學情分析：
我所帶的班級的學生英語基礎不錯，學生的好奇心和學習接受能力比較強。此外，在近兩年的英語教學中師生之間配合越來越默契 學生養成良好的聽力和討論習慣，所以本堂課可以充分發揮學生自主性，把課堂大膽的還給學生，他們一定會給我們帶來驚喜的。

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!
Step VI : Homework : Write a composition based on the debate Step VII. Reflection (反思：)
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!
