显微镜是中学生物实验最基本最常用的设备 ,学生是否掌握正确规范的使用技能 ,是能否顺利进行中学生物课一系列用显微镜观察生物细微结构实验的关键。作为生物教师 ,必须抓好这一关键 ,重视实验课“显微镜的构造和使用”的教学 ,下面谈谈我们的做法和体会。　　 1.课前精心准备 The microscope is the most basic and most commonly used equipment for biological experiments in middle schools. Whether or not students master the correct use of standardized skills is the key to successfully performing a series of microscope observations of biological fine structure experiments in secondary biology courses. As biological teachers, we must grasp this key point and pay attention to the teaching of the “structure and use of microscopes” in the experimental class. Let’s talk about our practices and experiences. 1. Prepare carefully before class
