第三、定語從句的用法教材的地位和作用：定語從句是高中英語教學(xué)中的一個(gè)非常重要的語法，也是高考的一個(gè)熱點(diǎn)。在英語里，定語從句可以使一個(gè)繁瑣的句子變得非常簡(jiǎn)潔，同時(shí)，它在人們?nèi)粘?huì)話中出現(xiàn)的頻率特別高。定語從句掌握地扎實(shí)與否關(guān)系到一個(gè)學(xué)生英語水平的高低。因此，定語從句的學(xué)習(xí)和掌握在英語學(xué)習(xí)中有著重要的意義。教學(xué)目的根據(jù)教學(xué)大綱的要求，通過這一節(jié)課的教學(xué)，要使學(xué)生知道什么是定語從句和定語從句的分類，掌握定語從句的用法。培養(yǎng)學(xué)生的觀察能力、分析概括能力以及演繹推理能力等。還要培養(yǎng)學(xué)生探索求真知的精神，對(duì)學(xué)生進(jìn)行實(shí)踐觀點(diǎn)的教育。教學(xué)的重點(diǎn)與難點(diǎn)定語從句是本課的主要內(nèi)容，與日常英語的應(yīng)用密切聯(lián)系，所以定語從句的概念與運(yùn)用是本節(jié)課的一個(gè)重點(diǎn)。對(duì)定語從句的復(fù)習(xí)，需要綜合應(yīng)用所學(xué)知識(shí)來解決原來的遺留問題，因而對(duì)句子分析和推理概括能力要求提高了。而高中生側(cè)重于對(duì)直觀現(xiàn)象進(jìn)行具體、形象的思維來獲得知識(shí)。因此這個(gè)知識(shí)點(diǎn)既是本節(jié)課的重點(diǎn)又是難點(diǎn)。培養(yǎng)學(xué)生的多種能力也是這節(jié)課的重點(diǎn)，這是素質(zhì)教育對(duì)現(xiàn)代教學(xué)的要求。二、分析學(xué)生大多數(shù)學(xué)生上進(jìn)心強(qiáng)，學(xué)習(xí)態(tài)度端正，有良好的學(xué)習(xí)習(xí)慣，但是缺乏一定的探索研究問題的能力。定語從句是學(xué)生在英語學(xué)習(xí)中比較常用的語法，也是他們必須掌握的內(nèi)容。教學(xué)中要注意培養(yǎng)學(xué)生對(duì)英語的興趣，充分發(fā)揮主體作用，迎合他們好奇、好動(dòng)、好強(qiáng)的心理特點(diǎn)，調(diào)動(dòng)他們學(xué)習(xí)的積極性和主動(dòng)性。高中生的思維方式由形象思維向抽象思維過渡，因此在教學(xué)中應(yīng)注意積極引導(dǎo)學(xué)生應(yīng)用已掌握的基礎(chǔ)知識(shí)，通過理論分析和推理判斷來獲得新知識(shí)，發(fā)展抽象思維能力。當(dāng)然在此過程中仍需以一些感性認(rèn)識(shí)作為依托，可以借助多媒體設(shè)備加強(qiáng)直觀性和形象性，以便學(xué)生理解和掌握。三、教學(xué)方法這節(jié)課可綜合應(yīng)用提問、歸納、介紹、檢查、講授和討論等多種形式的教學(xué)方法，提高課堂效率，培養(yǎng)學(xué)生對(duì)英語的興趣，激發(fā)學(xué)生的求知欲望。充分體現(xiàn)以教師為主導(dǎo)，以學(xué)生為主體的原則。創(chuàng)設(shè)英語情境讓學(xué)生參與語言實(shí)踐，邊動(dòng)口邊思考。從語言分析總結(jié)出結(jié)論以調(diào)動(dòng)學(xué)生的積極性。四、教學(xué)程序教學(xué)中要以了解、學(xué)習(xí)研究英語的方法為基礎(chǔ)，掌握知識(shí)為中心，培養(yǎng)能力為方向，緊抓重點(diǎn)突破難點(diǎn)，具體設(shè)計(jì)如下：新課導(dǎo)入：以創(chuàng)設(shè)問題情境導(dǎo)入新課。學(xué)源于思，思源于疑，一上課便以聽歌曲填空的形式引入課題，引導(dǎo)學(xué)生分析歌詞中的有關(guān)定語從句的句子，認(rèn)真分析句子成分，使學(xué)生產(chǎn)生強(qiáng)烈的求知欲和好奇心，調(diào)動(dòng)學(xué)生學(xué)習(xí)的積極性和主動(dòng)性。講授新課：任何語言學(xué)習(xí)都離不開語言實(shí)踐。這節(jié)課主要采用講授歸納的方法來建立定語從句的概念。我將一個(gè)定
