针对性 教师在讲解新知识时,根据内容的需要选好实例,有的放矢地介绍给学生,让学生在分析领悟中,能略见一斑,对新的内容能起到引导作用。如在讲自然带的垂直分布时,把自己登五台山所见的植被垂直分布的实况及照片介绍给学生,使学生宛如身临其境。在讲大地构造、大陆漂移说之前,先给同学们举如下的实例,在南极冰雪覆盖的大陆上已发现大型煤矿,在终年炎热的非洲赤道附近及印度地质工作者发现了古冰川遗迹,
Targeted teachers In the course of explaining new knowledge, they select examples according to the needs of the content and introduce it to students in a targeted manner. In analyzing and comprehending the students, they can see what they see and can play a guiding role in the new content.

Before speaking about the earth structure and continental drift theory, first give examples to the students. Large coal mines have been found on the ice-covered continent of Antarctica. Ancient glaciers have been discovered near the hot African equator and Indian geologists.
