一道题解法的繁简,一方面取决于题目本身,另一方面还取决于解法的选择.一道简单的题目,若解法选择得不合理,可能变得较繁.相反,一道很难的题目,当解法选择合理时,可能会变得很容易.因此,在解题之前,一定要克服思维定势,开阔解题思路,从多种解法中选择最佳解法.下面结合初中物理习题的解答谈谈具 The complexity of a solution depends on the topic itself and on the other hand depends on the choice of solution. A simple topic, if the solution is chosen unreasonably, may become more complicated. On the contrary, a difficult topic, When the solution method is reasonable, it may become very easy. Therefore, before solving the problem, we must overcome the thinking tendency, broaden the problem-solving ideas, and choose the best solution from a variety of solutions. The following is a discussion of the answers to the physics exercises in junior middle schools. Talk
