On the evening of June 8th, you must spend 1.5-2 hours reviewing physics to ensure that you can fully enter the state of physics after the first three intense exams, and at the same time, you should pay attention to ensuring that you have about 7 hours of sleep that night. On the morning of the 9th, some students woke up early, and it was inevitable that they were nervous and anxious. Here is a way to relieve stress-reading the relevant contents of the history of physics: find a quiet place to read aloud. The louder the better, the richer the feelings, the better. Read aloud and pour your nervousness and anxiety into reading aloud. When reading, the more you read, the more refreshed you feel. So many tall images of physicists seem to stand in front of you one by one. After watching it for dozens of minutes, I was sweating profusely, and the melancholy and anxiety when I first got up were swept away. I am full of enthusiastic fighting spirit and full of fighting power. At the same time, I also entered the state of physics. It should be said that it is absolutely good to take part in the physics college entrance examination with such a mentality.
1. Total control
After the bell rings, candidates should sit in the designated seats and set up stationery and certificates. Don't rush to answer the questions after the papers are handed out. Fill in the name, admission ticket number, seat number, etc. Put it in the corresponding position in the newspaper first. Then pay attention to counting the number and page number of the test paper, and check for missing pages, missing prints, damage, illegible handwriting, etc. It's in your test paper. If there is any problem with the test paper, report it to the invigilator in time. Browse the test paper from beginning to end in three to five minutes. How many questions are there? What is the score and distribution of each question? Have a comprehensive and preliminary understanding of the capacity and difficulty of the test paper to avoid the phenomenon of loose front and tight back when writing.
2. Easy first, then difficult
When I first entered the examination room, I was generally nervous, and my memory and thinking were not at their best. At this time, doing easy questions first can not only help you get the basic points smoothly, but also increase your confidence and stabilize your mood because of "fluency". Don't panic even if you see a problem that you won't do for a while, because the college entrance examination is an optional test, and the types of questions must have a certain degree of discrimination. Because the arrangement of the same question type in the test paper is also arranged according to the degree of difficulty, it can also be done in the order of the question number when doing the same kind of questions. The second is to be big first and then small, that is, to do big sub-questions first and then small sub-questions, and to lose as few points as possible in the case of insufficient examination time. The third is to be the same first and then different. You can do the same type of questions first, so that you can think more deeply, and then do different types of questions. When you encounter big problems, you should solve them in sections and score as much as possible.
Stay calm and stable.
It is very important to maintain a peaceful, calm and calm examination room mentality. Strive for strategic importance and calmness in action. Don't worry when the topic is difficult. Think of "I embarrass others, when I can't do it, others may not be smoother than me." Don't be ecstatic when the topic is easy. Thinking, "I can easily change people, I can easily do it, and others will certainly do it well." If you want to distance yourself, it depends on non-intellectual factors. "It is a skill to ensure that you will not lose points on the questions you can do. The topic is too difficult. When you can't figure it out after racking your brains, you can put it aside for the time being. But before handing in the paper, you must pay attention to the problems on the paper. Don't do it if you don't have time to do it. You can boldly take one or two points. You may not get points if you do it, but you will definitely not get points if you leave it empty.
Bold and cautious
Whether the meaning of the problem can be clearly investigated is the key to the success of solving the problem. Examining questions is the "basic gravity engineering" in the whole process of solving problems, so we should examine questions slowly and answer them quickly.
(1) fine
It is necessary to see clearly whether the multiple-choice question requires choosing right or wrong; This year's multiple-choice questions are multiple-choice, and multiple choices are not allowed. In particular, the judgment of multiple-choice questions is specious and easy to set traps. Don't be the same, and don't be sloppy, or you will make mistakes easily.
(2) All
Remember to finish reading the questions when reviewing them. The questions on the college entrance examination paper, except the information questions, are certainly not redundant. You must read the suggestive introduction to help you understand the original question. You can't ignore the words in brackets after the topic, such as: effective number, how much to take G, whether to consider the direction when solving some physical quantities, etc. Be careful when answering questions.
Don't start writing in a hurry without knowing the topic. To understand, it is important to understand the intention of the proposer, turn the real question into a physical question and establish a physical model. Otherwise, read it again and draw a sketch while reading until you really understand the meaning of the question.
When reviewing the questions, you should read them clearly word by word, find out the key words, ask for effective information, carefully analyze the meaning of the questions, and find out the proposition intention. You can even mark the known conditions, potential conditions and problems to be solved in the questions with a pencil, so that you can make a draft while reading the questions. If you try to draw quickly, you will start to do the problem before you can see it clearly. After you finish, you will find that you have either misread the meaning of the question or missed the conditions. As a result, the paper was dirty, the time was wasted, and the mood was destroyed. In particular, the questions of writing, expression and understanding of calculation should be answered closely, so as to be in place in one step.
Draw cards correctly
After the answer, focus on the answers to the previous multiple-choice questions. If you do one question at a time, it will not only waste time, but also affect the consistency of thinking in the process of answering questions. It is not good to draw a whole roll before drawing the card. If you hurriedly finish a complete paper and scribble the answers to the previous multiple-choice questions, then you will forget to scribble in a panic.
6. The roll surface is clean and tidy
Before you begin to answer questions, you should look at the answer sheet and estimate how much space you need to solve the problem. This can not only avoid writing down, but also make the problem-solving process clear and the paper clean and beautiful. Unclean paper and irregular writing will bring great difficulties to the marking teacher and will also become a factor of losing points. Especially in the face of the examination paper, the words are written in a dragon and phoenix dance, which will directly affect the mood of the marking teacher and let him lose some points that should not be lost in vain. Subjective questions are flexible and changeable, and human factors cannot be ignored.
(2) discipline strategy
Strategy 1: "four first and four later" is suitable for "quantity"
1. Easy first, then difficult. When answering questions, do the questions that are easy to score first, get the points that you can get first, have confidence in continuing to do the questions, and open the door to thinking. Generally speaking, the last item in multiple-choice questions is more difficult to do than the first item in each calculation question. I hope every student should pay attention to this.
2. Mature first and then grow. Look at the whole volume, and do the problems that you have mastered first. The structure of the questions is familiar and the thinking of solving problems is clear. In this way, while winning the familiar questions, you can make your thinking fluent and extraordinary, and achieve the goal of winning the middle and high difficulty questions.
3. Similarity before difference. Physics examination papers generally have three types of questions: multiple-choice questions, experiment and solution questions, and calculation questions. When you do the same type of problems first, your thinking is more concentrated, and the exchange of knowledge and methods is easier, which is conducive to improving the efficiency of doing problems.
About multiple choice questions. Multiple-choice questions are the first type of questions in the college entrance examination and the key questions for candidates to score. On multiple-choice questions, the idea of setting questions in our province is to let students get more points on multiple-choice questions, so the simpler they are, the more likely they are to make mistakes, so be careful. Generally speaking, 15 minutes is appropriate for the six multiple-choice questions that must be done, and it shall not exceed 20 minutes. The common skills to solve multiple-choice questions are: analysis method, special value method, exclusion method, limit method, hypothesis method and so on.
About experiments and short answers. It is the second kind of question in the test paper, which is characterized by small and precise. Except for the second experimental question, other questions are generally not difficult, but the students' foundation should be very solid, the contents of the teaching materials should be very familiar, and the requirements for concept analysis should be high. Therefore, when solving experiments and short-answer questions, we must be calm and careful, we must not take it for granted by feeling, and we must resolutely overcome the problem of "being right, not answering completely, and not getting full marks for correct answers". The time for answering such questions is generally controlled at 10- 15 minutes.
About the calculation problem. In recent years, there has been a great reform in calculation problems, which has changed from one topic to many problems, reducing the amount of calculation and increasing the amount of thinking. Calculation questions can be divided into three levels: ① The first question and each question are basic questions, which are the focus of candidates' scoring, and you can get full marks if you are careful; ② The second question should be considered as moderate in difficulty, which not only examines knowledge points, but also examines problem-solving methods and students' general ability to analyze and deal with problems, and the average student can also get full marks; (3) The third question of the last question (sometimes the last two questions of the last question) is somewhat difficult. This is a test based on ability to distance between candidates. If you can't get it, you must strive for one step at a time. Therefore, when we do these problems, we should have a physical overall situation, base ourselves on basic knowledge, pay attention to physical thinking methods, and pay attention to the establishment of physical models. The calculation takes about 25-30 minutes.
4. Be small first and then big. Small questions are generally less informative and easy to master, so don't let them go easily. Try to solve the big problem as soon as possible before doing it, so as to gain time and create a relaxed psychological foundation.
Strategy 2: Two "slowness" and two "quickness" complement each other.
1. Slow examination and quick solution. Examining questions is the first step in solving problems, and it is the basis and premise of solving problems correctly. The main methods of examining questions are: speaking like a book and grasping the eye of the question; In-depth analysis, grasp the characteristics; Pay attention to association and tap the meaning; If you don't understand, look at it from another angle. Correct examination of questions is the guarantee to determine the correct answer. After you have the correct solution, you should answer the questions on the paper as soon as possible in order to make effective use of the examination time.
2. Calculate slowly and write quickly. Examination time is limited, and candidates often pay attention to solving problems quickly, but there are negligence or clerical errors in calculation, resulting in undue loss of points. In the exam, the calculation should be slow and accurate once, and the accuracy of the calculation can be better guaranteed by slowing down the calculation speed appropriately; Write fast, the steps to solve the problem should be concise, don't drag your feet, and more importantly, prevent gilding the lily and wasting time.
Strategy 3: temporarily forget and transfer the situation.
It is normal to encounter the phenomenon of "temporary forgetting" in the physical concepts and cold knowledge in textbooks. Don't panic at this time, because it is caused by the inhibition of the cerebral cortex, which is temporary. When this phenomenon occurs, we should constantly carry out "calm" self-suggestion, skip doing other questions first, or try to associate by using the connection between knowledge. Commonly used correlation methods are:
1. Think backwards with fruit. When thinking positively, if the thinking is blocked, we can often make a breakthrough by using reverse thinking to explore new ways to solve the problem. 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.
2. Avoid the process of conclusion reflection. For open questions or exploratory questions or new definition questions, it is generally unnecessary to pursue the "yes" and "no" and "yes" and "no" of the conclusion. In the process of solving problems, various conditions are synthesized and strict reasoning is carried out, and the process steps are obtained, and the conclusion is self-evident.
3. Straighten out information and form a network. If it is because the information content of the test questions is too large, we can first find out the known conditions, excavate the implied conditions, eliminate the interference conditions, put forward the key data, tabulate or visualize, comprehensively relate and refine the relationship, and establish the physical model by relying on physical ideas and methods. Straighten out the information and network all the conditional information, sometimes the problem will be solved by the transformation of physical model.
Strategy 4: When encountering problems, handle them skillfully.
Pay attention to the following strategies in solving the problem that segmentation can't score:
1. Missing step solution. For difficult problems, the wise solution strategy is: divide a problem (such as the second or third problem) into a sub-problem or a series of steps, solve some problems first, to what extent, calculate several steps and then write several steps, and you may get a score for each step. Partial omission can make candidates from perceptual to rational, from special to general, from partial to whole, have an epiphany, form ideas and finally solve problems successfully.
Step by step. If the problem-solving process is stuck in an intermediate link, you can admit the intermediate conclusion and push it down to see if you can draw a correct conclusion. If you can't get it, it means that this road is wrong. Change the direction immediately and find another way. If we can get the expected conclusion, we can go back and concentrate on overcoming this transitional link. If it is too late to confirm the intermediate conclusion due to time constraints, you can skip this step and write the following steps to the end. In addition, if you can't do the first question, you can assume that the first question is "known" and complete the second question, that is, skip the solution. Maybe I remembered the middle steps later, or if time permits, I tried to catch the middle difficulties, and I can make up at the end of the corresponding topic.
3. Retreat for progress. For more general problems, if you can't get a general idea at the moment, you can take a special method (such as solving multiple-choice questions with special methods), turn abstraction into concrete, turn the whole into parts, turn parameters into constants, and turn weak conditions into strong conditions. In short, retreat to the point where you can solve the problem, stimulate your thinking by thinking about "special" and solve the "general" problem.
A good attitude should be: positive and enterprising, optimistic and open-minded, neither indifferent (how many times in life, don't wait at this time) nor too so-called (man proposes, God disposes).
