新编人教版初中《生物》教材在教学内容和编写方式上与老教材相比都有较大改观。尤其在编写中出现的许多新内容：如“动动脑”、“动动手”、“课外读”等，都将对现阶段及其今后教学质量的提高产生深远的影响。在不长的教学工作中，我对其中的“动动脑”尤其感兴趣，它曾对我? The new edition of the textbook “Biology” for junior high school teachers has greatly improved the teaching contents and writing methods compared with the old textbooks. In particular, many new contents appearing in the writing, such as “moving brains,” “kicking hands,” and “reading after class,” will all have a profound impact on the quality of education at this stage and in the future. In the short teaching work, I was especially interested in the “action brains”. Did it ever happen to me?
