Students ’mental state and teaching contents are different, timely put forward well-designed, purpose-oriented questions, which have a great effect on enlightening students’ positive thinking and learning mathematics. This article on the high school mathematics teaching suspect to talk about their own humble opinion. -, teaching should start from the contradiction of teaching From the beginning of the contradiction is open from the question, thinking questions and surprises since the beginning of the design of a difficult question in the teaching of students can be easy to answer or an interesting story, inspire students to strongly desire, play Apocalyptic-induced effects.
