一.前言中学动物学要求给学生的鸟类解剖知识,是一般的构造知识。因此,只要具有用肉眼能够观察清楚,而又具有一定代表性的鸟类就可以用作实验材料。人们常说:“麻雀虽小,五脏俱全”。事实正是如此。麻雀等小型鸟类的体形虽小,但它们的构造却具有典型性,解剖麻雀就可以了解鸟类的基本构造。麻雀等小型鸟类在自然界的数量多(其中有的是农业害鸟),比较容易获取大量的实验标本,可充分满足实验的需要。学生可以人手一只,每人都有机会动手解剖进行详细地观察。对提高实验质量,加强解剖的技能训练都有重耍作用。小鸟体形美丽,小巧玲珑, I. INTRODUCTION The knowledge of bird anatomy required for students in middle school zoology is general structural knowledge. Therefore, as long as they have a bird that can be clearly observed with the naked eye, a representative bird can be used as an experimental material. People often say: “The sparrow is small and fully-equipped.” This is exactly the case. Small birds such as sparrows are small in size, but their structures are typical. Anatomical sparrows can understand the basic structure of birds. Sparrows and other small birds are numerous in nature (among which some are agricultural birds) and it is relatively easy to obtain a large number of experimental specimens that can fully satisfy the needs of the experiment. Students can have one person and each person has the opportunity to dissect and perform detailed observations. It is important to improve the quality of the experiment and strengthen the training of anatomical skills. The bird is beautiful and small.
