构词法

复习课
中考
地位
分析
根据2017年的中考说明要求:1、要求学生了解构词法的基本知识,并据此判断常用合成词、派生词、转化词的词意和词性、词类。2、转化法的理解兼词类。本内容在中考中无具体分值,但通过了解构词法可以扩充学生的词汇量,以及更容易辨析一些词汇的词意和词性,是拥有丰富词汇量的一块大基石。
学情
分析
初三学生复习课,学生有一定的英语基础,但是并不好,上学期英语考试满分为100分,全年级的平均分只有49.41分,优秀率仅有2.22%。学生词汇量不多,能听得懂一些英语口语,能用一些简单的英语进行交流。学生自学能力较弱,可以按照教师布置的一些简单的内容进行预习与学习。目前,只有小部分学生能利用构词法理解一些生词。
