For candidates, how much they pay determines the final exam results. No matter which year, there is always the voice of spitting out the college entrance examination questions. For example, the clouds in the third country on 20 19, the Venus with a broken arm in the first country, the pyramids in 2020, the floor tiles in the Temple of Heaven and so on. Although these may just be similar words on the Internet, it also reflects that some people find these questions difficult, while others think they are just a piece of cake. Are we talking about this? Selective? .

In fact, from my point of view, these questions are all the same, but they look a little different with the breath of daily life on the basis of knowledge, and they are still very simple in essence. For example, the cloud in the third country is based on polar coordinates, and the floor tile in the Temple of Heaven is arithmetic progression. No matter how the college entrance examination changes, it is always based on the evolution of knowledge in textbooks. This is not only about these questions that only change in the form of expression, but also about multiple-choice questions and big questions, such as analytic geometry and functions.

If you want to make achievements in the college entrance examination, the first thing is the degree of foundation consolidation. I will give you a theorem. Can you tell me from which definition and how it is derived? Can you link it with other knowledge through this theorem? This is the level of basic knowledge. The second is the flexibility of knowledge. Knowledge is dead and man is alive. People should learn knowledge and learn how to use it. For example, we know that climbing stairs needs to overcome gravity to do work. We know that climbing stairs to a certain height, if the speed is different, then our fatigue will be different. So what does our fatigue have to do with it? It is definitely not work, because the work done is the same, so if we exclude the factors of work and consider time, the conclusion is that the degree of fatigue is related to time. The less time we have, the more tired we are, so the degree of fatigue is positively related to strength. After reaching this conclusion, we can extend it to machine manufacturing and other aspects. To test the threshold of machine work, we need to consider the power rather than the amount of work done.
