According to my observation, most teaching and research sections will arrange exactly the same questions according to their understanding of the thinking mode of last year's college entrance examination questions. The original question is definitely not available, but the motif is possible and may often be in the college entrance examination questions. Some teaching and research sections are not strong enough to come up with wonderful questions, while some think that they have grasped the core of the college entrance examination questions, and the imitation of thinking methods can be better, and even worse, the arrangement of imitation language and materials can be very good. In fact, in my opinion, the thinking method that can be close to the college entrance examination questions is a better set of simulation questions. I have done this kind of problem and feel much better than other simulation problems.
