一、教学目的的确定这篇课文记述了左光斗的几则逸遗闻,一方面通过语言、行动和肖像的描写表现他的为人,另一方面又以史可法作陪衬,进一步突出他的精神面貌。课文后的“思考和练习”、除就思想内容提出问题外,还就古汉语知识编写了两道练习题,一道是关于句子成份的,一道是关于介词和介宾词组的。由于介宾词组在句子中的位置不固定。加之介词后边的宾语有时又可省略,这与现代汉语有—定区别,所以,后一道题既是重点,又是难点。据此,本课的教学目的可确定为:一、学习左光斗为国家选拔人才,以国事为重,将个人生死置之度外的精神,并剖析课文中的消极因素;二、理解陪衬的特点和作用;三、掌握文言文中有关介词和介宾词组的知识,了解介宾词组的用法和同一介词在不同语言环境中的不同意义。二、疑难词句补说 First, the determination of the teaching purpose This text describes Zuo Guangdou’s several stories of rebellion, on the one hand, through the description of language, action and portrait depicting him as a person, on the other hand, with Shi Kefa as a foil to further highlight his spirit. face.
