First of all, you are right to want to read. I can see that you really want to study hard in high school. But the problems in life can't be solved by a book. Let's just say the impact is good. Of course, you have realized this. So, what kind of books do you want to read?
First, I strongly do not recommend inspirational books or so-called success books. Those books are nonsense, of course, they are basically right, but they are useless.
Secondly, I suggest you read some good popular science books and look for books written by foreign masters, such as A Brief History of Time and The Emperor's New Brain. Don't read popular science written by Chinese people (except "Does God Roll the Dice-A History of Quantum Physics"), or you can read some science fiction novels to enhance your understanding of science. Although your academic performance has not improved much, you will benefit for life.
Thirdly, reading history, Bai Yang's modern Chinese version of Zi Tong Zhi Jian is a good choice, or reading Historical Records (original version) is also very helpful for future China people.
Fourth, it is of little use to learn high school knowledge now, and it will not widen the gap with classmates, so there is no need to look at anything like May 3rd.
As a student who just graduated from senior three, I want to tell you that the enthusiasm now is not enough, but the enthusiasm that lasts for three years is important! Few people can persist in their efforts for three years. From my personal experience, most senior one students are playing with the past, and few of them study hard. In the second year of high school, some people wake up and start to get serious. Usually these people will make great progress. There is nothing to say in senior three. Those who don't work hard are those who give up, and most of them are working hard. Therefore, if you are determined to make a name for yourself in high school, the first year of high school is very important, and there is enough time to widen the gap between you and other students this year (so it is of little significance to learn high school knowledge this summer). Be steady in the second year of high school, don't force yourself too much, lest you can't run in the third year of high school. Senior three, the teacher will run with you, but you should also pay attention to yourself. There should be two lines when reviewing, one for yourself and the other for the teacher.
Now you are about to enter senior one. Let me tell you more about the first year of high school. As I said just now, most people are playing in Grade One, so even if you can't resist the temptation to play, it's nothing. Just work hard in grade two. For example, when I was a freshman in high school, I ranked 730+ in the whole grade at the lowest, and about 200 in the second year of high school. And our school can be said to be the best school in the city, with great competition. Therefore, three years of high school is still enough, and the focus is still on persistence. While studying hard in senior one, you should play with your classmates when you should, and relax when you should. Don't become a nerd.
In addition, the study in high school is very different from that in junior high school. After entering high school, you find that the biggest change is that there are more self-study classes. When you are in Grade One, you will find that there is nothing to do. At this time, we should adjust ourselves, have a look at the reference books, and learn the competition if we still have spare capacity. As for learning methods, the most important thing is to listen to the teacher. You don't have to take good notes, but you must understand what the teacher said. You can ask someone else to copy your notes, but the teacher can't tell you again like a class. In addition, if you have time, ask the teacher more, and you can ask anything, so that the teacher can feel that you like TA very much and like this subject very much, and TA will also pay attention to you and help you more. Teachers are human beings, and there is always prejudice. Teachers also like others to ask TA questions. Also, it is really useful to prepare the wrong textbook from the first year of high school. I didn't know how useful it was until less than a month before the college entrance examination, but it was too late.
To learn a foreign language, I recommend Oxford's bookworm series, most of which are abbreviated versions of famous books, and they are in English and Chinese. I suggest you read them all, so that you will never forget your sense of language, and the accuracy of doing the questions is extremely high. This is how I learn English. After three years in high school, I listened to no less than ten grammar classes, and also took the college entrance examination 133. And this book is not for you to finish reading in the summer vacation, but for you to keep reading every day, at least when you go to school on weekends.
As for Chinese, don't worry about it for the first two years, just recite the text well, and the senior three teachers will have a special review.
Mathematics, personally, is the most important subject, whether from the perspective of high school or from the perspective of future study. On the one hand, being good at math can help you get extra points; On the other hand, being good at math is of great help to your further study. To learn math well, on the one hand, we should concentrate as much as possible in class (absolute concentration is impossible, as everyone who has attended school knows), on the other hand, we really have to do some problems, and it is impossible to learn math well without practice, on the other hand, we should communicate with teachers more.
As for physics, high school physics is simple and patterned. For most problems, it is to understand the meaning of the problem, then express the physical process with equations and then solve the equations. In fact, the most difficult thing is mechanics, but the requirements of high school are not high.
I don't have any good suggestions for learning chemistry, just remember the properties of substances clearly and associate them. As for the study of chemical theory, I'm not sure. Personally, I used to be the worst subject in chemistry, but when I was in the third year of high school, I suddenly realized that it almost became my best subject.
The secret of biology is only two words: textbooks. Familiarize yourself with the textbook, remember what you should remember, and get 95% in the exam.
One more thing, taking part in more activities in high school, whether in school or in class, will be of great benefit, and these things will become your lifelong memories.
I hope my answer is helpful to you, and I wish you success in high school for three years!
