Derived from the third question, due to the online qhf incident, the third question actually only gave 4 points, and the scores of the first question and the second question both improved. This may also be the way for the Education Committee to protect us ... In fact, a normal high school student should also be able to write the first two questions and get most of the scores. Finally, adding them to paper won't be ugly.

In view of the problem that the department of solid geometry needs rigorous proof, it is because the examination questions are too difficult this year, and the marking is also under water. Write a rigorous department certificate and give this part a perfect score of 4. If you don't write, you will get all three points if you don't take advantage of the conditions given by the topic. For an ellipse, as long as it is connected, no matter whether it is connected correctly or not, it will give points. The sum of two roots and the product of two roots are the same.

The last question, the first question gives 4 points, and the second question gives 5 points. This score is reasonable, but the proof of the second question is actually relatively water. As long as we prove that there are no eight numbers when k=3, and then prove that k=4, we can basically get these five points.
