As can be seen from the above two tables, the changes in the starring roles compared with last year are in the following aspects:

1. The number of single choices increased from 14 to 15. , the score of each question remains unchanged, and the total score is reduced from 28 points to 30 points;

2. The number of multiple-choice questions remains unchanged, the score is reduced from 3 points to 2 points, and the total score is reduced from 12 points 8 points;

3. The number of fill-in-the-blanks is increased from 6 to 8, the score of each question is reduced from 2 points to 1 point, and the total score is reduced from 12 points to 8 points;

4. New reading questions are added, and the two parts are worth 8 points;

5. The scores for the comprehensive electrical and mechanical calculations are reduced to 4 points.

What is unexpected is that there are only 8 fill-in-the-blank questions, and other changes are as expected. All simulation training fill-in-the-blanks are 10. I was originally worried about whether the children would be able to adapt to such an unexpected situation. After careful consideration, it is unnecessary to worry about emergencies and should be done. Don’t speculate on the intentions of the teachers who set the questions. Just see Our exams, what they test, besides the ability to grasp knowledge, there is a lot more. What we study, besides the knowledge in books, there is a lot more. To be a good person before doing anything, you have to be able to adapt to life. Exams are also our life. Life is not static. Accidents will always happen. When they happen, what should we do? Only by staying calm and trying to adapt as quickly as possible can we best solve it! Questions are a test of learning, and accidents are a test of life. They are all tests of our inner qualities. I believe that children can do them well!

From the above two tables, we can see the overall difficulty ratio of this year’s questions There was an increase last year, but the increase in the difficulty ratio was not significant and was within the expected, controllable and acceptable range.

In terms of specific questions, we focus on the selection and fill-in-the-blank last questions (questions 15 and 27). Question 15 is about buoyancy and pressure, and the difficulty level is basically the same as last year's similar questions, while question 27 is about the same type of questions as last year. The balance conditions of the levers examined in the question are basically the same as last year. The difficulty of these two questions has basically not changed much. The power comprehensive and electric comprehensive questions that are the next most concerned are also basically the same as expected. They will not have the same difficulty as before 13 years ago. Last year For this year's most basic power comprehensive and electronic comprehensive questions, there are not even special models. They are all very conventional models. Compared with previous years, the difficulty has dropped a lot. For slightly better students, they are basically free points; this year's difficulty is instead It is added to the experimental questions, and there are more exploratory experiments. The six experiments on the mechanical efficiency of pulleys in question 40 are difficult to get full marks because there are too many details. However, this type of question is also a question that we usually train on. The score is also very easy. Questions 38 and 39 are two falsification experiments, question 33 is about using an electric meter to troubleshoot circuit faults, and question 35 is about measuring density using a special method. They are all difficult questions. You should focus on training in the future. Questions 34 and 36, one in thermal science and the other in electricity, are all about looking for laws, so they are not difficult. However, because they examine functional ideas that are closely integrated with mathematics, they are easy to lose points. The Joule heating experiment in question 37 in electricity only needs to be clear. This question is relatively easy to grasp the idea of ??controlling variables. The other experiments are all conventional test methods. Readings, density measurement with a balance, and side resistance in voltammetry are basically full marks as long as the calculations do not make mistakes. It can be seen from the experiment questions. In the future, the questions in the high school entrance examination will be more flexible and more closely integrated with life. It will focus on examining students' daily observation, thinking, and problem-solving abilities. In the future, they should be "careful people" and accumulate more life experience.

3. Deyang City High School Entrance Examination Comprehensive quality: It comes back to the question of what to test. What is tested is the basic comprehensive quality of knowledge, mind, adaptability, etc. The knowledge requires proficiency and flexible application. The mental requirement is to be calm and calm, and the second is to learn to observe, explore, summarize, analyze, and solve. The adaptability requires the ability to be calm when things change and the second is the ability to return theory to reality. It can be seen from the whole set of test questions that the examination of basic knowledge of physics is now more detailed and in-depth, and more emphasis is placed on students' practical abilities. Physics comes from life, and now it must be brought back to life again. Therefore, if you want to get higher scores, you must grasp the basics and experiments down-to-earth.
