How can a high school science girl increase from 514 points to 625 points?

The difficulty of the college entrance examination is the ever-changing problem. What I can give you is how to take the exam, how to train your problem-solving ability, but I have no ability to teach you how to solve the problem. There is no shortcut to solving problems, but there is a shortcut to training your own problem-solving skills. All I did was tell everyone how I was able to develop problem-solving skills with less energy than others.

One of the classmates said that it is necessary to look at the "feeling", and if there is a feeling, then there will be no. In fact, this is the most typical knowledge is not comprehensive or partial. The first step to solve the problem is to find out the problem. The first thing you have to do is to find out what you "do not feel" and see which part of the knowledge they belong to, or which type of question. If the former is easier to do, special training will be fine. If it is the latter, you should first look at whether the question type is the type of the college entrance examination, and if so, select the type of question from the set of questions. I will talk to you in detail later about the summary method of the question type.

The combination of functions, series, and derivatives. This part of the topic is often more difficult, but I do not advocate that everyone give up on it. Its characteristics are difficult to think about, but once you think of it, solving problems is faster. And "thinking" is what we can usually train.

For example, a problem is a comprehensive set of questions based on series. Students who have done a lot of questions should know that the first question is to find the formula, which is the most typical type of questions in the series, and also the hot spot of the college entrance examination. Even if it is a finale, the first question must not be difficult. And this kind of approach to the formula, there are only a few methods in the college entrance examination. Only by finding out the rules of your own can you use it freely in solving problems.

So how do you find your own solution? Maybe the first question you won't, well, look at the answer. After that, it is absolutely not possible to copy the answer, but to step by step and understand. What did the first step do, why do it, what did the second step do, why did it... until the whole process is understood, then cover the answer and do it again. You can make it yourself, then you have already understood this question. But not enough. In the end, what you have to do is to summarize, not rely on this question, use words to write down your entire problem-solving thinking, such as what to do in the first step, what to do in the second step.

At the time, I summed up one: when there is a double-column relationship equation in the title, the way to get to the formula is to find a more obvious formula, and to merge the first series of items into On the one side, 3, the equation of the pass in 1 is brought into the equation, and the second pass formula is obtained. Of course, this is just an example, not necessarily correct, but you can summarize the classic questions into the general rules of the text. The next time you encounter this type of question, you can put the law in the inside. This method of summarization applies not only to mathematics, but also to the wider application of chemistry topics. Of course, many students will find it a waste of time. That's right, I tried a whole night and I did a whole night repair. The reason why I ask you to do the set of questions is that you have the sensitivity to the college entrance examination questions, know which type of questions are possible, and which will not.

This method of summarization must be targeted, that is, it should be used in the questions of the college entrance examination. In particular, the trigonometric function, the probability problem, the three-dimensional geometry, the analytic formula in the analytic geometry, the formula and the summation in the series of questions, these kinds of college entrance examinations must not be able to make new ideas, and try again and again.

Talk about chemistry

Chemistry is really simple. I always think that it is the simplest subject in the five subjects of my exam. Moreover, there are not many things that chemistry needs to carry. Many people say that chemistry is a liberal arts in science. This is completely wrong! The students who use memory to learn chemistry, there are many around me, those who have 80 exams, they do a lot of questions, but they always do wrong. I feel very incredible. In fact, the most crucial thing about chemistry is to think about its ins and outs. Many people say that the knowledge of chemistry is very scattered and needs to be remembered. In fact, through thinking, many small knowledge can be found to be related to each other. Just like wearing a line to wear them all together, once a topic involves a knowledge in a thread, it naturally leads to the knowledge of the entire thread.

Like all subjects, the college entrance examination chemistry is divided into several blocks, basic knowledge, organic chemistry, electrochemistry, energy, solution ion balance, gas reversible reaction, structural chemistry, typical metal elements and their compounds, typical non-metallic elements and their compounds, experiment. The first step is still the same. If you have a piece of knowledge that you are obviously not good at, start the special exercise immediately. Similarly, you must use the college entrance examination questions. But unlike mathematics, chemistry can be used in thematic workbooks. Because the generality of general chemistry is not as strong as mathematics, a problem can have a lot of knowledge synthesis.

The chemistry questions are very clear. One problem must be to test a piece of knowledge, so you don't need to practice the comprehensive question deliberately. The so-called chemistry comprehensive question is a big problem with many big questions. The knowledge that each small question may use is different, but every time you answer a small question, the process of answering must be knowledge that belongs to only one piece. It is said that the college entrance examination chemistry is simple, and the most obvious is the independence of the chemical problem. In fact, it is very scary to get rid of chemistry. I used to participate in the chemistry competition. One of the problems can be combined with more than one piece of knowledge. This kind of topic is really difficult. But fortunately, it has nothing to do with our college entrance examination.

My gas balance is very poor. I found a weekend time to finish the big problem of the gas balance in the "5 Years of College Entrance Examination 3 Years". Then gas balance became the piece I was best at, and no problem with this piece stumped me.

Of course, there are many ways to do chemistry. First of all, special training is to find big questions to do. The selection of new questions is strong, and the knowledge of the examination is not comprehensive, and the specific exercises use comprehensive questions.

The multiple choice question is very important! Very important! ! Very important! ! ! If you want a good score, you can't miss more than one question! So I said that special exercises don't have multiple choice questions, not that you don't make multiple choice questions. On the contrary, the set of questions in your hands is now starting to play a role. The children of the comprehensive study must make sure to do a multiple-choice question regularly from now on! It is a complete set of questions, only a multiple choice question. Time, according to your two and a half hours 300 points, the multiple choice questions must be controlled within 45 minutes. Two sets of training on a Monday, it is best to reach about half an hour. The choice of questions is quick and accurate.

Here is a summary of the methods that have been discussed in mathematics. And this method is more widely used in chemistry. Because the routine of chemistry is actually very strong. Take the gas balance I have made as an example. In fact, if you turn all the questions out, they are the kinds of questions. And we usually have a fixed one of them. What I have to do now is to find the problems that I often don't do, to read the answers, and then to understand the whole topic from beginning to end. The key is still to understand that in this type of question, the first step should be What, what should the second part do. Until you can cover the answer and make it.

Finally, of course, it is still summarized as a textual experience, and it is written down. The next time you encounter the same question, you can set it up.

Chemistry is very important to think about. Be sure to think clearly about the ins and outs of the problem. You can't have a bit of a chain. The chemistry is very coherent, which is especially evident in the big questions. The key to chemistry to learn is whether you can rely on understanding to replace what others have to memorize. Now the bias of the chemical college entrance examination is to solve the actual problem, even if it is back-to-back death, it can not get high scores. Knowledge network, there is no need to deliberately build. It is very time consuming and cannot be directly reflected on the score. But one thing you have to do is to think about the principles of each problem and concept, and trace the source.

The summary method I am talking about below at least guarantees that the loopholes encountered in a large number of exercises will not be reproduced in the exam.

From the topic of a typical question type, the promotion to the law of words is not only a mode of thinking, but also extended to other similar topics. This method is very applicable, because there are not many questions for the college entrance examination proposition. But it does not apply to chemical problems alone. There are too many methods for the topic of chemical engineering. There are hundreds of different problems in an industrial production process. Therefore, there is no such typical thinking mode for chemical engineering. The method of extending from one question to many questions does not work. Then we only have the reverse, summarizing the common problems in many chemical problems, and getting a few high-frequency answers. Then, in the exam, when you can't directly think of the answer, you can go up one by one. In fact, there are a class of problems in the chemical industry, which is what I said earlier: What is the role of the xx step? Or why do you want to do xx? This kind of question is easy to answer directly, but when you do more questions, you will find that there are several answers to this question. for example. In the chemical problem involving dissolved crystallization, a problem often arises: What is the use of pH adjustment in the XX step? This problem has been bothering me for a long time, and it is hard to think of it because of many different situations, such as impurities and product formation. But when I put together the answers to the questions that appeared in the usual practice, I found that there are no more than two answers. 1. Prevent the hydrolysis of product ions; 2. Promote the ion hydrolysis of the magazine.

It is easy to have this summary. The next time I see this topic, I will put the two answers into the process. Non-1 is 2. Generally speaking, it is not wrong. Another example is also a common question: What is the use of burning products before industrial processes? I also summed up these few answers: 1, remove the oil on the surface of the raw material; 2, remove some flammable or easily evaporated impurities; 3, make some components oxidation reaction, generally in order to facilitate the later acid treatment. Look, this set of questions in the title is equivalent to making multiple choice questions. Is it easier to think directly than directly?

In my opinion, the students who are now 500 to 600 are middle-level students. You already have a certain ability to solve problems, and the basic knowledge is relatively solid, but you have not been able to apply knowledge to problem solving. What I teach you is how to train yourself to apply knowledge to problem solving. This is the ability to test. Middle-level students should mention the top students, not only to answer those rigid questions, but after all, the middle and upper levels in the examination room are the innovative questions that you will never see in your usual training.

Therefore, middle-class students, learning other people's problem-solving model, is not enough, even if you master those routines, the method is actually the same when you encounter the innovative questions in the exam, but you still won't change your clothes. You are still a middle class student. Therefore, you must be sure to train your own problem-solving thinking mode. This can be seen through the ever-changing appearance of the exam questions. At first glance, the so-called high-end questions of innovative questions are nothing but old things.

Introduce to everyone a few high school should develop habits:

High school, I dare to say that it is the most exciting and most memorable year in our life. All the energy is blooming at this time, so it will still shine even if it is short. How is the precious memory, so that even after many, many years, we will clearly remember the pile of exercises, the countdown to the day, the teacher who is very cute. No matter who you are, when you think of your third year, you will have endless emotions and surprises. For myself, I am so happy that I still have a dream of myself. Don't just stare at the scores and rankings of black pressure, let alone stare at the infinitely beautiful university of fantasy. You have to enjoy the process of this struggle. You have to tell yourself that I have only one year in my life. When the third year has passed, I will never have the opportunity to fight hard with my dreams. The third year should be hard work, but it should not be painful struggle. Learning should not be yours.

The first habit: You must give yourself a half-day vacation in a week, don't force yourself to die, then you will be suppressed and dark. Going to the college entrance examination in this mood and learning to relax moderately, you will meet the efforts of the next week with more expectation.

The second habit: don't arrange learning tasks during class, even if you don't recite words. You can't finish it. With the addition of classes in advance, there is not much time in your class. If you have time, just go to the brain and talk about what the teacher said in the previous lesson. Then you can take a rest on the table for a while, or you can look at the handsome guys in the corridor. High school students are the best, I always think so.

The third habit: go to bed early and get up early. The efficiency at 6 o'clock in the morning is much higher than at 12 o'clock in the evening. If you really feel that time is not enough, don't stay up late, get up early, you will have a surprise.

The fourth habit: Before going to bed every day, don't think about how many questions I have done today, how many questions I have to do tomorrow. You must think about what part of the knowledge I have learned today, or how to solve the question type, and I will contact that piece of knowledge tomorrow to answer which type of question.

The fifth habit: High school students have a lot of time to arrange their own time, and they must develop a fixed period of fixed subjects. Don't be free when you suddenly think about which subject, just do it. Even if your homework is not completed, wait until you have the time to do it. How to arrange the time subject depends on the time when you take the college entrance examination. For example, in the morning of Guangdong, the Chinese language examination is comprehensive, and in the afternoon, the mathematics is English Then you can read the language in the morning and do a good job at noon. I will do math problems in the afternoon and do English exercises in the evening. As for the evening repair, you can do homework, and at other times, you will be given a higher-level subject.
