In fact, this is a question of your own choice. You think it's worth it If you want to win the first prize in the Olympic Games, it will definitely have some influence on the college entrance examination, but it also has its advantages. For example, we are taking a comprehensive exam now, and I can work out the chemistry 108 question in 20 minutes at most. After the game, you will find that many things are very simple, such as a chemical equation, which you can't recite at ordinary times. There are many experimental phenomena. But after the game, you will find those things very simple, because you already know why it reacts like this. Even the deep things are clear, not to mention the surface.
My advice is, if you want to add points or enrich yourself, do it. But first, you should be prepared to have an impact on your grades in other subjects.
I think the key to the competition is to have the right teaching materials. You say your school is good, so I guess there should be such a training class, and I can attend it. Not in our school. They are all self-taught from the information found on the internet, which is very difficult.
Regarding books, I think the choice is very important. You should choose both books. If you just want to win the prize in junior high school and senior high school, you should focus on the competition books in this field, and the university textbooks only need to understand the relevant chapters. If you want to make a difference in the winter camp, you must thoroughly understand these two books. In fact, you can ask the teacher and ask the teacher who often leads the team for advice, which will be of great help to you. There are still many problems, many, many. Because chemistry is, after all, an experiment-based subject, the written test is basically a reasonable guess with certain knowledge. Sometimes the answer is bizarre, but it is right. If you haven't met it, you can't figure it out. For example, the question of Fe cooperation in this year's exam is very abnormal. I dare not think of that answer, but it is true.
Remember, if there is a competition, you must do it well, otherwise you must not do it. Don't worry about your other subjects at the same time, and then give up halfway, it will only pay off.
I quit QQ after the third year of high school. I think it is a waste of time, so I don't need it now.
I hope it helps you.
Supplement: Orsay classic books are really good to read. You can also look at the books recommended by others on the Orsay website. The teacher only talks about concepts. If you understand them, you should do more questions.
This is an excerpt from someone else:
"Your position in the chemistry competition will determine how much effort you have to make and the specific action plan (oh, I'm not teaching success ...). Different goals have different plans. I want to remind everyone: don't underestimate yourself! High standards and strict requirements are good for us. How to find the most suitable foothold between reality and dreams is something that each of us should learn and can only learn by ourselves.
Let's have a look. The red letters indicate the goals you set for yourself. For reference books selected for different projects, please refer to the "Reference Books" section.
Third prize: ... you'd better not participate and save some money. I have nothing to say to you.
Second Prize: Winning the second prize is a realistic goal for most students, because maybe you are not top-notch in chemistry, maybe your main direction of competition is not chemistry, maybe you don't want to spend too much time and energy on the competition and pay more attention to the college entrance examination ... Then, a second prize is still very affordable. As long as you prepare a little after the preliminary round and listen carefully in class in July, there should be no problem. But to be honest, the first prize and the second prize in chemistry are useless. Perhaps the knowledge and experience gained from the competition will be more helpful for your college entrance examination and further study.
First prize: first of all, see if you have mastered the contents of the exam outline, but not all? It's not your fault. I don't know where some of the contents about crystal structure in the syllabus came from, even structural chemistry ... but big things have to be mastered tightly. Don't wait until September to say, ah, I forgot to learn organic …
In order to increase the winning rate, you'd better attend the training in July the year before last. You should know that the results of the preliminary competition of senior one students will be reduced by ten points in April and May, and with a few floating places, the possibility of passing the preliminary competition of senior one students is still very high.
Provincial Team: Someone asked, "Hey, why did we jump from the first prize to the provincial team?" Because I hope you don't target the top 40. Either you follow the plan of the first prize, or you aim at the provincial team, which I made clear at the beginning of the "training team" part. If you must aim for the top 40, you can be more proficient on this basis according to the plan of the first prize above, do more simulated test papers and read more college books ... Just do it, there is no qualitative difference, after all, take a good exam in September, 10, and wait for abuse!
Before the implementation of the new college entrance examination scheme, students with the qualification of walking students can not take the final exam of non-elective subjects, which is equivalent to not taking the academic level exam, but now they have passed the academic level exam before the chemistry competition, so there is no way …
Aim at the students of the provincial team, and your plan will be completely different from before. You must devote yourself to chemistry and make much more efforts than others to succeed. People multitask, even multitask, and there are not many successful examples in the end, but I think they rely on several times of efforts, rather than cutting one effort into several parts. If you have this kind of consciousness, I won't object to your doing so. Some people in the chemistry training team also won the first prize in physics. People in Nanwai told me that some people in Nanwai were qualified to take three courses of mathematics and physics at the same time, and some even joined the provincial team in the past.
Of the 44 people in 2007, two came from 2006, one was a sophomore, and a dozen won the first prize in 2006.
Competition books are hard to buy in Zhenjiang, and all kinds of Olympic guides are ok, but college textbooks are troublesome. There are almost no bookstores in Zhenjiang (there is an underground bookstore on Zhongshan Road, which seems to be called Star Bookstore, where there are several kinds), so if you have the opportunity to go to Nanjing (for example, during the winter vacation training, during the training in July the year before last), you must buy books. There are various teaching materials on the third floor of Xinhua Bookstore in Xinjiekou. The books sold in Nantah's main bookstore are so professional that there are almost no textbooks for junior college students. You can buy physical books there. Try not to be reluctant to spend money when you buy everything at once in Nanjing, otherwise it will be more troublesome to regret buying less when you go back to Zhenjiang. Also, the book is very heavy, so you'd better carry an empty schoolbag when you go, otherwise you will go shopping with heavy things on your back ... There will be a booth selling college chemistry textbooks at the registration office when you report for training in July, but unless you are a freshman or a sophomore, it will be too late to buy it, and your chemistry competition will end in eleven days (cold joke ...) ... If you entrust someone else to buy it, you must make it clear, press (.
One more thing to note: we all use textbooks from the chemistry department of the university. What I recommend below is that if you buy textbooks from other universities, you must read the contents of the books and say who they are for. Books for non-chemistry majors are not acceptable, because they are very different from the regular textbooks of the chemistry department in terms of content division, difficulty and order, which will make you very confused.
National High School Chemistry Competition Standard Textbook
Editor-in-Chief: Ma Hongjia, Jiangsu Institute of Chemistry and Chemical Engineering, organized by the Senior High School Students' Chemistry Competition Working Committee. Cover of Southeast University Press: Green
You don't need to buy this textbook. It will be distributed in the training in July. Of course, if you want to have it in advance, you can buy it in Zhenjiang. This book is too general. It just lists the training contents in July like an outline, and I can hardly learn anything. After July, the only value of this book to me lies in the last two pages of the outline (in fact, the reference value of the preliminary outline is not great, and the final outline is completely nonsense. Do not believe! The preliminary contest here refers to the national preliminary contest, which is used for the exam in July and September), but it is an official textbook and must be used in class in July (think of Zhenjiang Daily). Anyway, there is no book with a wider coverage. You can get a general idea of the contents involved in the chemistry competition. You can do the above exercise, but I haven't done it …
Inorganic Chemistry (Volume I) Fourth Edition
Cover of Higher Education Press edited by Beijing Normal University, China Normal University and South Normal University: blue
This can be said to be a necessary book, and almost everyone who has participated in the chemistry competition has it. You can borrow it from someone you know who has participated in the chemistry competition. There are a lot of books in higher education with this cover design (inorganic, organic, analytical, materialized and so on). ), the top of the cover reads "2 1 century curriculum textbook". Mr. Wu Guoqing, the editor of this book, is the main figure in this chemistry competition. This book summarizes all the contents of inorganic chemistry (except elemental chemistry), including structure, materialization and analysis. It is the most basic college textbook and the earliest college chemistry book you should read. His writing is colloquial and suitable for self-study. Many contents of this book are required by chemistry competition, and some are not required by national preliminary competition, such as Nernst equation, electrolyte solution and some complicated calculations in chemical kinetics, etc. However, I suggest that you read this book more times if it is important, less times if it is not important, and you don't need to read it in order until you are familiar with every paragraph in it. This will be beneficial and your chemical literacy will definitely improve. Your time to participate in the competition was originally. Many people have turned this book into rags.
organic chemistry
The organic situation is special. Xinhua Bookstore is selling more than a dozen organic university textbooks at the same time (I mean basic organic textbooks, so don't buy a professional book specializing in one aspect of organic). You may also get some old organic textbooks that are no longer sold from various sources. The contents of these textbooks are basically the same, but each has its own characteristics, big and small, thick and thin, and voluminous. You can choose it yourself, as long as the basic content is the same as other versions. Students should not choose the same one, so as to exchange the advantages of different versions in the future. No matter what kind of organic textbook, as long as you can read it well (this is the key, much more important than a perfect textbook), it is enough for the national preliminary contest. For the students of the provincial team, please see the introduction of the book Basic Organic Chemistry below. I bought organic chemistry myself, and the layout is the same as inorganic (blue cover) (but it seems that even with such a layout, there is more than one kind of organic …), which was compiled by Dalian University of Technology and edited by Yuan, with less than 500 pages. Compared with other organic textbooks, it is a little simpler, with only one book, regardless of the first and second volumes. The contents are arranged in the order of alkynes, halogenated hydrocarbons, alcohol phenol ethers, aldoquinone, carboxylic acid and its derivatives, nitrogen-containing compounds, heterocyclic compounds, sugars, amino acids, protein and others. There is nothing unusual, and the basic content is not missed. My organic knowledge basically depends on it (of course, I have come into contact with other organic textbooks, but they are only fragments).
Basic Organic Chemistry (Third Edition) Volumes 1 and 2
The Cover: Yellow and White, organized by Peking University Higher Education Press, etc.
This book is only recommended for students who aim at the provincial team!
This is the most difficult basic organic textbook I know. The first two volumes *** 1200 pages are also very expensive, adding up to 100 yuan. The content is all-encompassing, and some of the reactions mentioned in it are said to be the work of the late Mr. Xing Qiyi himself and his disciples, which are naturally not found in other books. I suggest that students who want to learn this book should choose a simple organic book to read first, and then read this book after the university has a certain foundation, otherwise they may be overwhelmed by a lot of information. I bought this book late and only read more than 300 pages. If you can really understand this book, you can say that your organic ability is invincible. Even in the training team, not many people have finished reading this book (but not without it, it seems that someone in the training team has recited this book ...).
Fundamentals of structural chemistry third edition
Editor's cover of Zhou Gongdu Duan Li Anyun Peking University Publishing House: cyan
This book is easy to recognize, because structural chemistry seems to be the only one, nothing else. This is a textbook for senior college students, and its content far exceeds the requirements of the national preliminary competition. Maybe you will find it hard to understand when you read it for the first time, but I think this is a rare book. It can be said that one of the important reasons for my first prize in chemistry in my sophomore year is that I read it at that time. The content in the book is the theoretical basis of the whole chemistry discipline. Without these theories, chemistry will always be just an empirical subject. Exposure to these theoretical ideas will change your understanding of chemistry (at least for me). If the competition is compared to chopping wood, then reading college chemistry textbooks is sharpening the knife, and reading structural chemistry is sharpening the knife. It set up a picture in my mind and made me understand why "chemistry is a part of physics". All chemical phenomena are complex and beautiful patterns derived from countless microscopic particles that obey Schrodinger equation, and one equation creates the whole material world. This understanding of chemistry has also become my motivation to learn chemistry.

Some people say that chemistry is a liberal arts science, which is a bit extreme. However, chemistry competition does have its distinctive features. Compared with math and physics competitions, chemistry competitions have much more contents to recite, and they are basically based on university knowledge, and even have nothing to do with high school content. In a sense, this is a good thing: your high school chemistry level only needs to pass the preliminary competition, and the rest of you have never studied it, so you are on the same starting line. This feature also requires students who take part in chemistry competitions to have strong self-study ability. Of course, this ability is gradually acquired in the process of participating in high chemistry competitions.
This is obviously a matter of opinion. I can only tell you some general contents. How to find a specific learning method that suits you is your own business.
First of all, you can't succeed in the chemistry contest just by doing an exercise with enthusiasm. You should know what you are doing now. You should make good arrangements and know what you are good at, what you are weak at, what books to read, what questions to do, what to supplement and what to consolidate. I ask the female students to pay special attention to this point, because some female students always seem to be reading silently, lacking the overall grasp of learning, which is a big failure in the competition! At that time, you will be very painful: I have made the same (or even more) efforts, why can't I get a return? Because your strength is not used where it should be, you are wasting your strength. This is also a lack of awareness and understanding of the game. Know the game, know how much, and how high you can reach. Don't be a bad karma, but actively think about the organizers' intentions, what kind of people they want to select and what kind of abilities they will examine. Note: the contest was originally prepared for you, and you are the masters. I think you can listen to what Wu Yong has to say in this respect. The above can be summarized as "clear understanding". This sounds a bit mysterious, you may say: in the end, I just need to do a few more questions correctly and do well in every exam. I can take chess as an example: although in the final analysis, playing chess will kill the opponent, it has not evolved various abstract statements such as "chess potential" and "chess style". Of course, the so-called understanding is still based on a specific level of knowledge. Without a certain level, it is impossible to know.
Second, we should fully realize the necessity of cooperation. It's not far to work hard alone. It is necessary for several familiar students to discuss and argue together from time to time. In the process of answering questions with others, you can have a deeper thinking and understanding of the problem, which is sometimes far better than thinking hard. You must never have the idea that the enemy is strong and we are weak. Treating others as enemies will only make you suffer. Creating a good atmosphere of competition, cooperation and progress is good for everyone and depends on everyone's efforts. In 2007, eight students from provincial middle schools entered the first round of training, ranking first in the province. I have more contact with them. I think such brilliant achievements are partly due to their good classmates. The above can be summed up as "good cooperation atmosphere".
Today, I discussed reading with a classmate who was engaged in a chemistry contest. I said: maybe reading some books will not be of direct use to the competition (because it exceeds the requirements), but it can raise awareness and improve chemistry literacy ... my classmate seems to be a little more intense. I put his words here for your reference. He said: anyone who reads any book should first look at whether the syllabus requires what to read and try to read as few books as possible. In short, if you don't want to read books beyond the requirements, then you can't read the books within your requirements well. (to this effect)
I hope everyone can find a balance between curiosity and utilitarian purpose. Don't be too utilitarian, quick success will not lead to a good end (I never doubt this), and don't be too romantic, otherwise you may not pass the preliminary contest with a far-sighted vision, and even the best will be buried.
Don't be afraid to use new knowledge to break the old ideas in your mind.
In the above article, I unconsciously repeatedly stressed the need to seek a certain balance among various dialectical relationships, hoping that I didn't give you the wrong impression that I am good at politics.
Fourth, organic.
Organic chemistry is the most memorable part of chemistry, and it will make you miserable when you first learn it (only slightly better than memorizing English words and politics for me). You can only read a dozen pages in an hour or two, which is easy to get confused and make people crazy. In this regard, I have no particularly good way, just tell myself "these are all knowledge!" " "Endure it. When I noticed that the number of pages I read slowly increased, I still felt a sense of accomplishment. But don't neglect the quality of reading for the sake of progress. If necessary, you would rather go back and master it at once.
It is definitely not enough to read it once, and it is impossible to master it at once, no matter how good your memory is. Generally, you have to read a book two or four times from beginning to end. As for dozens of key points in the book, I can say that I have to read them countless times. When I was most familiar with my organic book, I turned it over four or five times a day, which was exactly what I was looking for. One page is not bad, and I know it like the back of my hand. You can mark the page number of important content on the title page for easy reference. When you read this book for the first time, you should try to remember everything you see, and then you will naturally find the key points that you often do. Read it again, and you will realize the difference between backbone and sideline. If you have a general grasp of it organically, your heart will be much more practical.
In short, it is necessary to achieve proficiency through various means. One is to know enough organic knowledge, and the other is to be able to think of relevant knowledge when doing the problem. The former depends on reading books, while the latter depends on doing problems.
Finally, I want to say: there is no end to learning, and there is no end to learning. You should make yourself like learning, at least don't hate learning. If you can't find a reason to put up with learning this extremely boring content; If you study just to satisfy your parents; If learning this knowledge only brings you endless pain, then I advise you not to force yourself. After all, not everyone is suitable for studying. You should think about yourself, not work against your will. I don't think there will be a good result if you go against your heart. "
