《人教版高二英語選修8教學(xué)設(shè)計(jì)》
一. 教材分析
本課是人教版新教材選修8 Unit2 Cloning(Reading)，本課的中心話題是克隆。本文具體介紹了植物與動物克隆的區(qū)別、多麗羊的誕生與死亡及由此引發(fā)的爭論。幫助學(xué)生進(jìn)一步認(rèn)識克隆的意義在于解決醫(yī)學(xué)上的難題，為人類服務(wù)。本節(jié)課的目的旨在讓學(xué)生讀懂文章的意思、了解文章的內(nèi)容、把握文章的中心，從而提升自己的閱讀能力，要讓學(xué)生學(xué)習(xí)了解克隆這門技術(shù)以及有關(guān)的爭議，使學(xué)生了解克隆技術(shù)的優(yōu)缺點(diǎn)，學(xué)會表達(dá)和支持個人觀點(diǎn)，能用所學(xué)的有關(guān)Cloning的詞匯去表述自己對這一新技術(shù)的觀點(diǎn)和看法。
二.學(xué)情分析
高二年級的學(xué)生學(xué)習(xí)態(tài)度端正，學(xué)習(xí)興趣濃厚，愛觀察愛思考，樂于參與英語學(xué)習(xí)活動，且學(xué)生對克隆都有所了解，但閱讀技巧的訓(xùn)練比較欠缺，而Unit2 Cloning又是一篇介紹克隆技術(shù)的說明文，專業(yè)性強(qiáng)，文中生詞多，學(xué)生理解難度大。
總體來說學(xué)生的學(xué)習(xí)方式存在著差異，在教學(xué)上要做到分層次，教學(xué)方法有區(qū)別。

2. 學(xué)會克服生詞障礙，通過略讀，尋找文章的主題句，理清文章的總體框架與脈絡(luò);通過尋讀, 捕捉文章的重要細(xì)節(jié)，理解作者的寫作意圖。
過程與方法：
通過自主探究以及小組合作學(xué)習(xí)等方式，通過閱讀技能的訓(xùn)練幫助學(xué)生養(yǎng)成科學(xué)的閱讀方法。
情感態(tài)度與價值觀：
1. 通過本課的學(xué)習(xí), 學(xué)生能激發(fā)自己勇于求知、探索科學(xué)奧秘的積極學(xué)習(xí)態(tài)度，并形成積極的情感態(tài)度，主動思維，大膽表述，提高語言實(shí)際運(yùn)用能力。
2. 通過本課的學(xué)習(xí), 學(xué)生能夠?qū)W會一分為二地辯證地看待事物，形成科學(xué)的價值觀。
四.重點(diǎn)與難點(diǎn)：

reading, careful reading等閱讀技能;
(2)對文章深層次的理解及細(xì)節(jié)的欣賞，認(rèn)識及了解克隆技術(shù)。
2.難點(diǎn)：(1)閱讀技能的訓(xùn)練;

六.教學(xué)輔助工具： 多媒體等 七. 教學(xué)過程與方式
Step I Revision and Lead-in
Put a basin of cactus on the platform to attract the students’ interest and attention and
lead-in.
Show some pictures of Dolly the sheep(多莉羊)、A strawberry plant(草莓植物)、 Twins(雙胞胎)、 Growing new plantson the screen. Get students to look at the pictures and discuss:

Step II Pre-reading
Before class, ask the students to search for some information about this topic. Now show the questions on the screen, and then let them work in pairs and discuss about cloning. Ask the students to list the questions they want to find out and then share their lists with their partners. Questions about cloning:
1. What is a clone?
2. How is a clone produced?
3. What benefits can humans gain from cloning?
