What are the skills of Guangyuan senior high school entrance examination?
1, retreat for progress, stand on a special footing and diverge generally.
For a relatively general problem, if you can't get a general idea at the moment, you can take the general as special, such as solving the problem by special methods, from abstract to concrete, from whole to part, from parameters to constants, from weak conditions to strong conditions and so on. In short, retreat to the extent that you can solve it, and further enlighten your thinking by thinking and solving the "special" to achieve the purpose of solving the "general".
2, hold the cause, reverse thinking, difficult is the opposite.
When the positive thinking of a problem is blocked, using the method of reverse thinking to explore new ways to solve the problem can often make breakthrough progress. Push forward if you have difficulty, and push back if you directly prove that you have difficulty. If you use analytical methods, start with positive conclusions or intermediate steps to find sufficient conditions; By reducing to absurdity, we can find the necessary conditions from negative conclusions.
3. Avoid affirming and denying the conclusion and solve exploratory problems.
For exploratory problems, it is not necessary to pursue the "yes" and "no" and "yes" of the conclusion, and all conditions can be combined at the beginning for strict reasoning and discussion. In this way, the steps come and the conclusion is self-evident.
abstract
No pains, no gains. I hope all high school students can enter their ideal high school without three years' efforts.
