1、形容詞比擬級(jí)的用法講解與練習(xí)高密市立新中學(xué)李偉一、原因分析：1、英語(yǔ)中形容詞的比擬等級(jí)這一用法與漢語(yǔ)語(yǔ)言習(xí)慣有著很大不同, 因而學(xué)生在理解和使用上會(huì)存在一些障礙。2、英語(yǔ)形容詞比擬級(jí)有著很多靈活多變的使用方法，學(xué)生初次接觸 這 一語(yǔ)法，需要老師進(jìn)行必要的指導(dǎo)。二、采取措施：1、從形容詞原級(jí)的用法開(kāi)始引入比擬級(jí)的用法。2、使用多媒體等教學(xué)手段，給學(xué)生創(chuàng)造交際環(huán)境。3、采用小組、同桌、師生之間的多種交流、 討論的形式， 進(jìn)行對(duì)話 練習(xí)， 學(xué)習(xí)、理解并正確使用該語(yǔ)法。三、教學(xué)設(shè)計(jì)：一 、教學(xué)目標(biāo)：1、 掌握一些常用形容詞的比擬級(jí)的形式。good better; bad/illworse;fat -
