《琥珀》是根据一块裹有苍蝇蜘蛛的琥珀,假想它的形成和发现过程。由于它是一篇文艺性的科学故事,离学生生活实际较远,读起来乏味。为此,我认为应该扣住“淹没”一词导读,以突破松脂球的形成和松脂球化石的形成这两个难点。“淹没”一词在文中出现了三次,含义有明显区别。 Amber is based on amber, a flies spider, and supposes its formation and discovery. Because it is a literary story of science, far away from the student life, read boring. To this end, I think we should catch the “flooded” guide, to break through the formation of turpentine balls and rosin fossil formation of these two difficulties. The word “submerged” appears three times in the text, meaning there is a clear distinction.
