In high school biology teaching, whether teachers ’questions, demonstrations, exercises, etc., should inspire students’ thinking in various ways. In heuristic teaching, teachers inspire students to think seriously by trying to establish new and old knowledge Make conjecture or judgment, and guide students to gradually solve the problem so that they can take the initiative to participate in the learning activities.First, create inspiring situations, motivate students to actively think about any problem can find a solution to the problem, in the process of teaching The same is true, so according to the content of the textbook, teachers should create sound situations that inspire students to think seriously, and in the process, students find ways to solve the problem, for example, in the section on “The Structure of Ecosystems” When I created a problem situation to inspire students to think.First, using the pictures in the textbooks and teachers provide structural analysis of the ecosystem diagram, the question: the ecosystem
