一、初读感知。借助汉语拼音拼读生字,学生试读课文,初步了解课文内容,知道课文写了一件什么事,是怎么知道的。学生读后教师可启发学生讨论、探究,然后形成共识:读懂这本“最大的书”能为建设祖国作贡献。课文倒数第二段中“读了这本岩石书……能为祖国找到更多的宝藏。”这句? First, the first reading of perception. With Chinese pinyin spelling students, students try the text, a preliminary understanding of the text, know what the text has written something, how do you know. Students after reading teachers can inspire students to discuss, explore, and then form a consensus: read this “largest book” can contribute to the construction of the motherland. In the penultimate paragraph of the text, “read this rock book ... find more treasure for the motherland.”
