A few years ago, the school's retirement office and the student journalist corps jointly organized an event. They asked some middle school students in remote areas to write letters to our school teachers, mainly to some retired professors. The students who wrote the letters did not know any of the teachers, and the scholar-journalist corps simply distributed the letters to a random group of teachers and asked them to write back letters to the students.
I was lucky enough to receive a letter from a student. This student is a third-year science student in Guizhou Province who is about to take the college entrance examination. In the letter, he asked a number of questions. He said that he had a lot of questions, and hoped that the teacher who received the letter would take a good look at his questions and answer them.
I took a look, and there were two questions about academic Xi, especially the Xi in the third year of high school, and one question about Beijing, for example, he asked what was going on in Beipiao. The other one is about the new college entrance examination. I don't know anything about the new college entrance examination. So the answer is very straightforward and simple. It's just that I really don't know much about the new college entrance examination. For Beipiao, I also gave a simple answer to satisfy the curiosity of this classmate.
About the Xi aspects of learning. The two questions are:
First, how does a round of Xi keep up with the rhythm and how to be full of "strength"?
In the letter, he said that until now, the round of re-Xi in our school has reached the stage of being in full swing! But I feel that I can't keep up with the rhythm, and I know that I should have worked hard to do it, but I can't use any strength, and I look like I'm in a hurry every day, but I don't know what I'm busy with. A round of Xi is a bit like "cold rice and hot rice" to me, and I can't improve it. I'm on top of the line now, but it seems a bit difficult to get into a good school!
Maybe he writes more colloquially, so it's more concise. In general, it is a little lost in the Xi.
My answer to him was that for the re-Xi or the first round of re-Xi, the basic concepts or basic concepts of each chapter should be clearer first. Generally speaking, students think that some concepts and definitions are relatively simple, and they often do not put enough effort into these concepts. In fact, it seems that it is not easy to figure out and understand the concept that seems simple. Sometimes it is necessary to pick out the words carefully. If you really understand the basic concepts, it will not be difficult to understand the theorems and laws related to the concepts later.
In addition, when reviewing Xi, there are always a lot of Xi problems to do. After doing the Xi exercises, you should carefully understand some of the Xi problems that you will not do, or that you have done wrong, and where the problems are. Is it because of my unclear concept, which leads to misunderstanding, or because I have not found the right path to solve the problem? Don't let go of any of these mistakes, and we must find out the reasons for the mistakes, so that it is possible to solve the problems in a targeted manner in the Xi.
The second question is: how can the Xi of science be efficient?
He said that although I am a science student with pure physico-chemical biology, my science grades are not outstanding, and I even have points. There is always a hurdle that I can't overcome in my science Xi, that is, I can't "calm down and think", every time I think about a problem, my mind flies, and I can't help but "run" to other places to "swim". Chemistry is the most difficult thing for me to understand, I always feel that books often just give you this conclusion, but do not tell you why, for example, the electrolytic cell (original electrode) is a redox reaction, accelerating the reaction rate, but not why, if I want to give an example I can't give examples, but usually I will always be troubled by such a question! So I want to ask some science Xi methods.
I don't know much about what he wrote in his letter, but I just speculated. I told him that if he couldn't calm down, he might just not know how to recover Xi, how to grasp the key points, and how to be targeted. So you may want to get everything back Xi, but because the focus is not prominent, you are always at a loss. Here he needs to have a careful understanding of the answer to the first question I gave him, or to grasp the basic concepts. When it comes to redox, it's important to start with the basics. It is necessary to figure out what the concept of oxidation is, what the concept of reduction is, and what kind of relationship exists between the two.
In addition, when resuming Xi, it is necessary to allocate the time for resuming Xi scientifically, and a course should not spend too much time, because after a long time, the energy will be insufficient, and the efficiency of resuming Xi will be greatly reduced. So when you Xi a course, it's good to be able to solve one or two problems that you didn't know well in the past. At this time, you can put aside the resumption of this course for Xi time and go to Xi another course. In this way, the energy of re-Xi another course can be relatively concentrated, and the efficiency will be higher.
In addition, science courses are generally more rigorously logical. Mathematics is the most logical, followed by physics, chemistry is second, and biology is the most logical. If you can grasp the logical connection of the course content, then the Xi will be twice the result with half the effort. If you can't grasp the logic, then no matter how much time you spend, the effect of Xi will not be too ideal.
In short, in the process of Xi, don't be too impatient, don't think about completely grasping the content of the Xi at once, this is unrealistic. But it is necessary to follow the steps, the road must be walked step by step, and the meal must be eaten one bite at a time. You can't run too fast, and you can't stop moving. If you continue to walk calmly, the foundation of Xi will be more solid and you will get good benefits.
The so-called cold rice is hot. This cold rice actually has a bit of an illusion. You look like you're cold, as if you knew and understood everything in the past. But if you read the textbook a little more and study the basic definitions, you will find that this cold rice is not as cold as you think. Cold rice makes you feel no freshness. But if you seriously and steadfastly Xi your heart, you will find that this bowl of so-called cold rice has a lot of content that is still very fresh, still very chewy, and still very good taste.
The student also wrote that in the third year of high school, they didn't seem to have much motivation in their Xi, and asked me to tell my story to motivate him.
I don't really have any inspiring stories to tell. I just told him that when he entered college, he must not relax his Xi. When some students enter university, they suddenly lose their energy in their Xi, and as a result, they have to drop out. As long as a student insists on studying Xi seriously, no matter what kind of school he reads, no matter what kind of major he studies, and persists in his Xi, he will definitely have a good harvest.
He also asked the question, whether it is better to study in a "one-book" university in Beijing or a "211" school in this province. I replied that it was all for the school and for the person. However, my advice is that, if possible, I should come to Beijing to study at university. After all, Beijing will broaden your horizons and make you observe the world from a higher foothold. These advantages may not be so prominent in this province.
The school press corps asked us to write a reply, preferably with a pen, not typing on the computer. I listened to them. Write back four pieces of letter paper. But after all, because I haven't used my pen for many years, my wrist hurts so much when I write. I had no choice but to grit my teeth and endure it.
