What are the important high school mathematics, physics and chemistry competitions about high school

Oh, it's always a lot of effort, and it's a balance of learning, but it's also very rewarding. The first prize of each subject of our school provides Tsinghua University and Peking University guaranteed and independent places, and the second prize provides independent places. However, if there is an imbalance, the 10 points of the 1st prize + may not make up for the lost points in the English language.

I did a physics competition, which was very time-consuming, but the recognition of physics was very large. In short, it's up to you. I recommend a book to you, one name is the physics competition, the green book.

There is also a high school physics competition training course. Before the game, I did a pre-game training camp.

Competition actually has pros and cons If you get the award, of course it's good, there are extra points, and if you don't do it well, it will be submitted, but if you are not very talented in mathematics, physics and chemistry, it is recommended not to spend too much time on it, otherwise the gains outweigh the losses I am also from Anhui I think middle school students mathematics, physics and chemistry are very good There are a lot of questions and training about the competition Yes, I have used...

If you are not strong enough, you should try it in the second half of the second semester of high school, so that the learning method of the competition can be used in the college entrance examination as much as possible; Of course, if you have the confidence to keep going, you can get the first prize or even a winter camp, so that you can be sent to Tsinghua University, Peking University or your favorite school, it is not impossible.

High school subject competitions include mathematics, physics, chemistry, biology, and computer science. Computers are relatively unpopular, mainly doing pascal programming; The disconnect between chemistry and biology and high school knowledge is very large, and it mainly gnaws at college things; Physics is based on high school knowledge and some college-like calculus-solving methods; Math is completely high school, but it's much, much harder, and there's actually a lot of math that you haven't seen before.

Everyone is engaged in competitions, and the books that I started at the beginning were probably the "Peiyou Tutorial" of Zhejiang University, and the quality of that set of books was good, which was suitable for beginners in competitions. Shaanxi Normal University's "Olympiad Mathematics Course" and "Physics Competition Course" are also good, but chemistry and biology are not very good. I don't know much about the other books, but when I look at the book market, it's basically the same.

I'm not from Anhui, so I don't know about the competition training camp But Zhang Zude of the University of Science and Technology of China has a good chemistry competition, and if you have a chemistry competition, you must listen to his class.

The whitelist event has been screened and recognized by the Ministry of Education, and the gold content is relatively high

1. Candidates' interest exploration and cultivation: The exploration and cultivation of candidates' personal interests play a vital role in their future study and life. In learning, with the traction of interest, you will get twice the result with half the effort, and only those who are interested will take the initiative to think and study, so as to cultivate the ability to think independently.

The good habits formed by candidates in the process of exploring interests also indirectly affect the cultivation of personality and other aspects.

2. Discipline literacy development: Each discipline has a corresponding way of thinking, and participating in the event can exercise the discipline thinking ability and expand the discipline literacy. Moreover, after the establishment of disciplinary thinking, it is also very helpful for the in-class learning of the subject and related disciplines, which will make it easier to see problems and learn knowledge.

3. Broaden your horizons and hone your mind: Participating in the event should compete with the masters in the same field in the province and even the whole country. Some of the events will also have academic frontier lectures and some interesting activities.

4. Increase the chips for special enrollment and further education: Candidates who participate in the competition in high school and win awards can increase their chips and improve the acceptance rate when they participate in the special enrollment such as the Shaochuang class in the second year of high school and the model Wu strengthening plan and comprehensive evaluation in the third year of high school. Among them, the events recognized by the comprehensive evaluation in previous years followed the changes in the competition white list released by the Ministry of Education, and the recognition of Zhengyou events in the list was high, and the pass rate of candidates with relevant awards was high, and candidates who paid attention to the comprehensive evaluation focused on participation.

Meaning: Eligible to take the independent entrance examination.

To be honest, it doesn't mean anything, you can only add a touch to your resume.

The National Middle School Students' Mathematics, Physics and Chemistry Specialty Competition is held by giants, and after the preliminary examination, the first, second, third prizes and excellence awards will be divided according to the proportional line (that is, you are eligible to pay **), and then let these people pay ** (similar to **sex learning), and then decide who can enter the finals (the first and second prizes can be passed casually, and the third prize can be passed seriously). After telling you that you have entered the finals, you will be asked to pay money to participate in what training camp or something, and the so-called national first, second and third prizes will be determined in the training camp.

I also won the first prize in physics, chemistry and mathematics in the preliminary competition, and I made thousands of friends in physics and chemistry to participate in the training, but I decided not to go.

The landlord, you won the second prize, which means that these two sciences are good, but this certificate is really useless, at most you can add an attachment when applying for independent enrollment and applying for Hong Kong schools, and it is not as some people say that you can get independent enrollment places or even direct promotion places, this is really not.

I think if you are good at math, you can work the mathematical modeling competition, which still has a certain gold content.

The sophomore in high school is not easy, I won the first prize in mathematics, and this year's questions are much easier than last year.

means you qualify for the finals

How much did you score in math???

What's the deal with physics and chemistry being the same?

If you're in the summer vacation of your sophomore year of high school, it may be a little late. If LZ is not very knowledgeable about each discipline (i.e., the problems encountered so far are very simple), it is recommended that LZ focus on one subject. First of all, you have to have a huge interest and really love a certain subject, and it is difficult to hold on to it just for the purpose of adding points.

The other is to ensure that there is a lot of energy. Because competitions take up a lot of time. Take me as an example, the evening self-study in the second year of high school was all used to study the content of the competition, all the make-up classes during the summer vacation, and the class was suspended for a month before the exam and soaked in the laboratory.

And our contribution is still relatively small compared to other schools. Then, the competition requires you to build a deep understanding of the subject and a very rigorous thinking. To do this, LZ needs to have a good coaching environment (experienced competition coaches) who always think about what they have learned and what problems they have encountered.

This process is often difficult and painful, but it also comes with increased capacity. Perseverance is all about whether you can solve the questions you encounter.

Finally, I would like to send a sentence to lz, in the competition, the pay is often not proportional to the gain. After all, only a very small number of people get the success of the competition, and in the end, they have to go to the field to take the exam, and there are too many objective factors (I am so tragic). Therefore, I hope that as long as the landlord has experienced it and gone all out, he will not regret it.

2014 seems to be the year of the college entrance examination for LZ. At that time, the bonus point policy seems to change dramatically, and it seems that those who win the national finals will be given extra points or guaranteed. It's hard for those of us to fight against those who have only learned one subject since the first year of high school.

It's a bit tight on time, but I think you have to set your goals, make a detailed plan, schedule it, and move on step by step.

In addition, you must be optimistic about when to take the exam, when to sign up, what questions there are, and you can't report every subject, find one that you are good at, specialize, and people must believe in themselves!

Option A is based on n=m m, and then combined with the valency of each metal after the reaction with sulfuric acid, the amount of H2 substances formed by the reaction of the three metals with sufficient sulfuric acid is obtained N 46, N 18, and N 56 respectively (the specific calculation process uses the chemical equation, or the equation summarizes the simple algorithm available for the fill-in-the-blank question: valency mass molar mass 2) The "2" is from "H2".

It is required that aluminum and iron produce less hydrogen than sodium, so the acid cannot be sufficient. If iron and aluminum are required to release the same amount of hydrogen, there must be an excess of aluminum. From the equation, the amount of sulfuric acid and the amount of hydrogen produced are equal (except for the reaction with sodium) n 46 and n 56, and the answer is finally obtained.

This question is a multiple-choice question, and I have a more exaggerated method of reasoning ( o ). It's a long story, but it only takes a few seconds to analyze.

1.The sulfuric acid reacting with sodium must be insufficient, and sodium must also react with water d to eliminate. 2.

There must be an excess of aluminum, otherwise it would not be possible to produce as much H2 as iron (there may also be an excess of iron, but there is no need to consider that complexity here). 3.The key to the calculation of this problem is the iron element (aluminum does not participate in the reaction, so the calculation of hydrogen production should be based on iron), so the calculation result will be related to the molar mass value of iron 56, excluding iron and aluminum as much hydrogen produced by the reaction of acid, so the result can be equated.

To sum up, choose A

Quick way to complete this problem:

Observe the acquaintance of the answers, there are two 56, two 1000, and three are less than or equal to, and only A meets these three conditions at the same time, so choose A.

ps: For this kind of multiple-choice question, you have to master the skills, like this kind of question, you don't need to calculate, you can get the answer by logic, which is also the intention of the questioner, or why not a fill-in-the-blank question? Being able to make multiple-choice questions quickly also saves time for doing other questions.

Hope it helps.
