部编人教版四年级下册《小英雄雨来》说课稿（二）
一、抓住特点说教材《小英雄雨来（节选）》部编版小学语文四年级下册第六单元的讲读课文，课文节选自作家管桦写的同名中篇小说，讲的是抗日战争时期，晋察冀边区的少年雨来，聪明勇敢，游泳本领高强，为了掩护革命干部，机智地同敌人作斗争的故事。我在解读本文时特别关注了三点：一是故事情节跌宕起伏，将一位热爱祖国、不畏强敌的少年英雄塑造的活灵活现。二是文章中有些语句含义比较深刻，三是课文分六部分，每部分用空行隔开，便于训练学生的归纳概括能力。教学目标：1.自主学习字词，会认“晋、扭”等17个生字，会写“晋、炕”等15个生字，理解字义，识记字形。2.体会雨来的英雄品质，激发爱国情感。3.品味课文如何进行环境描写，体会这样描写的好处。
