How can I learn more about science, history, and history?

Science: First of all, you have to fall in love with the subject, you have to be serious in class, and you can preview it after class.

If you want to learn physics in science well, you have to do a lot of questions. Don't memorize the formula in physics, you can understand it by doing a lot of problems, so the effect will be better.

As for chemistry, all I can say is rote memorization.

If you're new to junior high school, I suggest you buy a book from the (Science Explorers) series, but other books are acceptable. But I want you to take a look. I'm a junior high school student, so please trust my advice.

History: If you want to learn a course well, there is a very important way, that is, to weave knowledge in your mind and heart! Horizontal and vertical crossing, complicated but not chaotic.

For example, in the first part of history, you should familiarize yourself with the textbook and grasp the content of the textbook more familiarly. The second step is to sort out a clue yourself. The knowledge in the book is mixed together and needs you to straighten it out, which is also the so-called "reading the book thin". For example, make a large table, using the chronology as a clue, and arrange the events of each year in detail by time.

In a table, take the country as a clue to rank what has happened in a country over the years, and come from country to country. So you make up a net, the vertical line is the time, and the horizontal line is the country. Every time you memorize it, you first memorize it according to the time line, and then memorize it again according to the national line (of course, it takes a few days to memorize the whole time), and slowly you will find that you have been able to understand it, and it is no problem for others to ask, because a clear context has been formed in your mind.

In fact, this can be described as a summary. I also want to tell you that if you want to learn a course well, you don't need to ask for more difficulties, you should first read the book thoroughly, and if you are interested, then read other related books, because the textbook has been summarized by many teachers over the years, which is aimed at the difficulty and breadth of the students; Second, there are too many related books on the market, and you may be difficult to distinguish between the official history and the wild history, even if the official history is too detailed, you don't need to read it. "Throwing money on the doctor" is likely to backfire.

Others can be the same, some may need more clues, that is, in addition to the horizontal and vertical lines, you may have to weave a diagonal line, but as long as the vein is formed, first, you can memorize it more scientifically, and second, you can grasp it more comprehensively and can understand it thoroughly. This is the motto of one of my people, and it was also taught to me by my teacher, and I also enjoyed my history class, and I wish you success.

Whiteness: Ask questions.

It's useless to offer a 100-point bounty because no one knows what you're trying to ask.

It can be supplemented; I have time.

Check in every day and accumulate experience points.

Read more information and learn more things, so that you can better help others, and at the same time, you can also improve.

Possibly, but it is advisable to look up the literature.

There are a lot of things, some information is not particularly easy to check, your good patience should be able to find.

There are many products, such as "web search" the most common, and then there are other common products. In web search, all you need to do is enter a keyword, and that's it; You can watch the news on the news platform; In addition, if you sign up for one, you can travel in the post bar, know, encyclopedia, and library. And your own space.

You can listen to the song and sing the song, but I heard that you will have to pay in May, because the previous *** was a pirated platform, because of the recent **copyright dispute, so it has been decided to officially launch the genuine** platform in May.

Enter ** directly, and enter what you want to know on the page.

** Web WAP Paste Bar WAP knows.

Geography: You must listen carefully to what the teacher says in class, take notes, once you have to have it, you must ask clearly, you can't come up if you fall, I just didn't listen to it at the beginning, and now you can't do anything, you really can't, buy a geography reference book.

Science? (I see that the science questions written by others are physics, I don't know if you are talking about it): write down all the formulas and theorems, and you need to do more questions to learn to use them; You have to be serious when you do the test, and it is very likely that you will have such questions during the exam, depending on your usual accumulation.

History: History has to be memorized by rote, and that's how I was, and I did well in the exam.

Biology: In the first year of junior high school, it is okay to memorize by rote, and when you are in the second year of junior high school, you must listen carefully, there is about genetic composition, it is impossible to memorize here, only if you understand, you will.

Maybe I'm not thinking about it enough, and you have to think of something yourself, but these are just a piece of advice for you!

Read more and think more, especially geography and maps, no need to deliberately memorize, the so-called familiarity with the essence of thinking is this principle.

In fact, this kind of class is good as long as you listen carefully in class, don't spend too much time after class, it's best to take notes, some knowledge points are not in the book, and the teacher will supplement them when he is in class.
