Analysis on the True Questions and Answers of Science in National Volume B in 2022
What are the skills of comprehensive answering questions in college entrance examination?
First, do the questions in order: it is best to do the questions in the order of subjects. Because comprehensive management is the integration within the same subject, the knowledge system, thinking methods and answering ideas of the three subjects are different. Answering questions according to topics can make your thinking continuous, thus improving the accuracy of doing questions. In these three subjects, do your own strong subjects first, and then do your weak subjects. This can be completed and scored in the shortest time, leaving more time for vulnerable subjects.
Second, carefully examine the questions: read through the whole question. It depends not only on the stem of the question, but also on the questions to be answered. It is necessary to fully and correctly understand the meaning of the problem and clarify the requirements and contents of the problem.
Review key words. Such as excessive amount, small amount, colorless, acidic, alkaline, sufficient reaction, short period, etc. Words such as static, uniform speed and free fall in chemistry test questions and physics test questions.
Requirements for examination of topics. For example, write "electron", "simple structure", "name", "chemical equation" and "ionic equation".
The breakthrough to solve the problem. That is, the breakthrough point of solving problems is the key information of solving problems, especially all kinds of inference problems and organic synthesis problems.
View valid numbers. Accuracy of instruments used: such as burette 0.01ml; Display of known data: for example, weigh 9.50g sample; Requirements in the title: if the result retains two significant figures.
The type of examination paper does not indicate the type of question in the preface, but there are different ways to ask the same question, so there are different answers. Therefore, the question type determines the direction of the problem, the method of solving the problem, and the expression of the result. Mixed questions are the characteristics of college entrance examination questions.
Third, easy before difficult: when solving problems, easy before difficult can enhance self-confidence. If you encounter a problem that is difficult to solve at the moment, you can skip it temporarily and make a record on the grass paper to prevent you from forgetting it. After finishing the easy questions, save time and then tackle the difficult ones.
Some candidates are excited when they see that the topic is relatively simple or familiar. They lost their vigilance and were careless. Sometimes, if they seem very familiar with the problem, a slight change in keywords or conditions will make mistakes. Such a topic is precisely the easiest to lose points. What we should think of here is that, generally speaking, it is extremely unlikely that the college entrance examination questions are exactly the same as the daily training questions, so we must take them seriously and never lose points.
There are also some candidates who will be afraid of difficulties when they see the difficulty of the test questions, which will affect their confidence in answering them. At this time, we should clearly realize that if you find it difficult, others will not be easy! As long as you calm down, carefully examine the questions, draw pictures and analyze them in depth, seemingly difficult questions will be solved.
It involves information questions, knowledge transfer questions, new scenario innovation questions, etc. , large amount of information, long text. We should be good at grasping and refining useful information. Most of these problems belong to "high starting point and low starting point". The knowledge and problem-solving methods used are the basic knowledge and methods learned every day, and the general answers are relatively simple.
If you encounter a problem that you really can't do, you can't deduct points or leave blank. Calculation problem: some ideas should be expressed in subject language (theorems, laws, etc. ), and the chemical equations involved should be written; Multiple-choice question: Choose the answer that you think is most likely.
If time is tight and you can't fully interpret it for a while, then give up bravely and check the questions you want to do in the rest of the time to make sure that you don't lose points.
Fourth, the first volume of answering questions.
Be calm when you do the first volume, not too fast. There are also many methods used in this kind of questions, which are very skillful. Such as: conservation method, steady state method, relationship method, drawing method and so on. Biology and chemistry questions are single choice, and for those questions that are not sure, exclusion and reasoning can be used; There are one or two answers to physics questions. If you are not sure, after you decide an answer, don't guess other answers, otherwise one is right and one is wrong, and the result is still zero.
The answer to the second volume of verb (verb abbreviation) should be standardized.
The standardization of the answers in the second volume is a problem that candidates should attach great importance to, and irregular expression is the key to losing points. For example, chemical "PH value" is written as "pH value"; The position of chemical bond connection is inaccurate, such as: the structural formula of hypochlorous acid is "H-O-Cl" written as "H-Cl-O"; Special nouns have typos, such as "benzene" written as "stupid" and "crucible" written as "clamp pot"; The equation is not balanced, or balanced but not reduced to the simplest ratio, or the reaction conditions are not specified; Inaccurate language description and so on.
Normative expressions mainly include: expressions that meet the requirements of the topic; Expression conforms to the characteristics of the subject; Expressions that conform to writing habits and so on.
Some language expressions with fixed formats should also be mastered:
The function of the equipment is generally answered from two aspects: it is beneficial to ... (the advantage of this assembly) to prevent ... (the disadvantage of not being assembled in this way).
To measure the quality of the sediment obtained in the experiment, it must be carried out in the order of filtration, washing, drying and weighing.
In the narrative process, the thinking should be clear, the logical relationship should be strict and the expression should be accurate; To train the ability of writing and expression, we should start from the basics, write words, sentences and professional languages, strive to be concise, answer the questions to the point and grasp the key points.
Sixth, ensure the accuracy of problem solving.
The comprehensive examination questions are difficult, and the answer time is very tight, so it is impossible to review them comprehensively. Therefore, we should solve problems accurately, improve the accuracy of one-time answers, and don't expect to review. At the same time, trust your first impression. Without special assurance, it is best not to change the first answer casually When you have time to review, you should focus on reviewing the first few questions, because you are nervous at the beginning of answering questions, your thinking is often affected, and you are more likely to make mistakes.
What should I do after the college entrance examination?
1, relax and have a good rest
For three years in high school, we stayed up late and got up early. The college entrance examination is over, so you can have a good rest! You can choose to spend three days sleeping well, cleaning up the housework, sorting out the used study materials and giving them to your brothers and sisters. The way books and papers circulated wildly on the Internet are vented is insulting. You must relax yourself and adjust your mood after the exam.
2. Take the driving test
Whether you plan to buy a car or not, learning to drive will be an indispensable skill in your future life. During college, spare time can be used to read books, participate in community activities, carry out social practice and complete self-appreciation. After entering the job, the increase of work pressure and irregular rest time make it difficult to complete driving school study in a short time. So these three months are the period of learning driving school.
3. Look at your favorite book
Without an exam outline, you can enjoy reading books you are interested in; There is no standard answer, so you can read critically and read some "useless" books. Read classic works, broaden your thinking and horizons. You know, universities are places where hidden dragons and crouching tigers are hidden, and reading is a way to improve one's self-cultivation.
Step 4 develop a hobby
Because I am in high school, I have to give up my hobby for a while. These three months are a good opportunity for you to pick it up again. Learn a musical instrument, practice calligraphy, play ball, dance street dance and embroider cross stitch. Do what you like and strive to develop into a specialty. You will find that people with special skills will have more opportunities in the future.
5. Give yourself a graduation trip.
Travel is undoubtedly huge for people's growth, such as early route planning, consumption planning, accommodation booking or simply setting up tents; All kinds of people, things or things encountered on the way; Self-summary after the trip. I think this is also an adult trip for children who have finished the college entrance examination. Learn to take responsibility, learn to make choices, learn to grasp and give up, and learn to persist.
Step 6 plan for the future
Enough rest and play, the next step is to plan your future. The turning point of life during the college entrance examination means the beginning of a new life. Whether you choose to continue your studies or enter the society, you must have your own ideas.
7. Prepare to fill in the volunteer matters.
After the college entrance examination, the next thing is to fill in the volunteers. As the saying goes, 7 points depend on grades and 3 points depend on volunteers. If we don't prepare in advance and make mistakes in filling in our volunteers, we will easily fall off the list.
8. Say "thank you" to those who accompany you.
It is never too late to be grateful. The season of June is not only the graduation season, but also the thanksgiving season. Thanks to the teachers, parents, relatives and friends who have been encouraging, accompanying and silently paying. Visit old grandparents more and spend more time with them in this unrestrained time.
