《看云识天气》是一篇通俗的科学说明文。中学生对云和天气变化的关系,是有一定的感性知识的,但是,他们不一定能系统地认识各种云的形状、光彩变化与天气变化的关系,即使有所了解,也不一定就能完整、生动地表达出来。所以,教这一篇课文,可以从“看、识、说”三方面着眼。看和识,可说是课文标题的一双眼,它指明考察的对象和研究目的,无疑是我们理解课文的纲。关于看,应先引导学生理解作者看到些什么、怎样看,进而研究如何学会象作者那样地看。为此,不妨在讲解课文之前,让学生先列举一下自己平日看到的云层的一些现象,以及它们同天气变化关系。然后,再对照阅读课文,从中学习它条分缕析地观察研究事物的方法。 “Looking at the weather in the cloud” is a popular scientific exposition. Middle school students have a certain amount of perceptual knowledge about the relationship between cloud and weather changes. However, they may not be able to systematically understand the relationship of various cloud shapes, luster changes, and weather changes. Even if they understand it, they may not be able to understand it. Full and vivid expression. Therefore, to teach this lesson, we can focus on the three aspects of “seeing, knowing, and speaking”. Looking at knowledge and understanding can be said to be a pair of headings of a text. It indicates the object of study and the purpose of the study. It is undoubtedly our understanding of the outline of the text. To look at it, we should guide students to understand what the author sees and how to look at it, and then study how to learn to look like an author. For this reason, before explaining the text, students may wish to enumerate some of the phenomena that they normally see in the clouds and their relationship with the weather. Then, in contrast with reading the text, I learn from it to observe the methods of studying things.
