教学片段一:师:作者是怎样把燕子的各种不同的美描写出来,让我们感受到是那么具体生动形象的呢?先看第一自然段描写燕子的外形之美。燕子身上的每一个部位都写了吗?生:写了燕子的羽毛、翅膀,还写了尾巴,然后是整体。师:一只燕子还有头,有眼睛,有爪子,为什么不把这些也写下来呢?生:他是抓住特点来写的,所以不是每样都写。 Teaching a fragment: Teacher: How the author describes the different beauty of the swallows, let us feel is so specific and vivid image? Look at the first paragraph describes the natural beauty of swallows. Every part of the swallow who wrote it? Health: wrote a swallow's feathers, wings, also wrote the tail, and then the whole. Teacher: A swallow still has a head, eyes, paw, why not write it down too? Student: He writes by seizing the features, so not everything is written.
