能否一眼看穿原来的解法?是否有更一般的方法?是否有更特殊的方法?这些方法各有什么特征?方法之间有什么联系?通过多种不同解法的比较,能否找到更满意的解法?这个问题可以引出哪些有价值的东西?偶然中是否隐含着某种必然?这题的哪个方面还可以给我有什么好的启发?这个结果或解法是否可以用于其他问题的求解?能否将这个问题的结论变形、推广?能否改变一下某一个条件,结论会怎样?
Is it possible to see through the original solution at a glance? Is there a more general approach? Are there any more specific methods? What are the characteristics of each of these methods? What are the links between the methods? Can we find more satisfactory Solution? This question can lead to what valuable? Incidentally implied some kind of inevitable? Which aspects of this question can give me any good inspiration? The result or solution can be used to solve other problems? Can the conclusions of this issue be distorted and promoted? Can we change a certain condition and what will happen?
