补白,就是引导学生在文章的空白之处进行合理的推断、预测和联想,并将推断、联想的结果通过语言或文字进行表述。由此可见,补白教学艺术能有效地推动课堂教学的发展,充分挖掘学生的想象力,使得他们获取知识的途径不再局限于课本。 Filtering is to guide students to make reasonable inferences, predictions and associations in the context of an article, and to conclude that the results of the association are expressed in words or words. This shows that the art of filter teaching can effectively promote the development of classroom teaching, fully tap the imagination of students, making their access to knowledge is no longer confined to textbooks.
