Ask for help about chemistry biology how to learn English on your own

I can't help you with liberal arts, chemistry, biology, but English, the main thing is to memorize words, and the upstairs says that I do a lot of questions, which is to work on grammar If the words are not familiar, no matter how good the grammar is, it is useless Words are not at all I don't want to know a lot I just want to remember what I have learned That's okay As for how to memorize words, you can ask someone to help you dictate Not much, dictate more than forty a day, and then revise after listening, read the right again, remember the wrong one, and then listen to all the words once a week This is a deepening image As for how to memorize the words, in view of the fact that the landlord said that he would not do it at all, then use the most stupid method to read more words When reading, every letter of each word is pronounced out to be read out silently, it is easy to forget it You can also memorize words by remembering phonetic transcription, but this is generally used after English has a certain foundation, but the method of remembering phonetic transcription is very useful and practical, and some words that have not been learned can also be written through phonetic transcription.

The amount of words can not be urgently asked for a lot of shorthand methods on the Internet, but shorthand is easy to mix up It is recommended that the landlord come step by step Don't be in a hurry I can't eat hot tofu in a hurry A winter vacation time is enough for you to memorize most of the words in the first semester of high school.

In high school chemistry, it is basically about the reaction of acid-base neutralization to form salts, and then about the displacement reaction of metal activity, which is mainly about these two blocks. Acid-base neutralization is basically 3 kinds, hydrochloric acid (called chloric acid in some places), sulfuric acid, nitric acid, among which the reaction of dilute hydrochloric acid and dilute sulfuric acid is exactly the same. The third is the reaction of concentrated sulfuric acid and concentrated nitric acid, which has strong oxidation and the equation is different.

In general, concentrated sulfuric acid and concentrated nitric acid should be understood, and they will not be studied in depth. Another important point is that some salts are precipitated, such as barium sulfate, calcium carbonate and various precipitates. This kind of score is too unjust.

The next is the displacement reaction, this is simpler, just remember the metal activity OK, potassium, calcium, sodium, magnesium, aluminum, zinc, iron, tin, lead, hydrogen, copper, mercury, silver, platinum, pay attention to the rise and fall of valency, use more active elements to replace the more inactive metals, the valency increases, is oxidized, loses electrons, the valency of the reduced metal is reduced, is reduced, and electrons are obtained, commonly known as rising and losing oxygen, and the drop is returned. The most important thing is trimming, the atomic weight must be balanced before and after the reaction, which belongs to the mathematical basis. Biology,In fact, it's the liberal arts in science.,There's no way to take a trick.,It's basically back.。。

I don't have much to say about what I memorize.

The knowledge points of chemistry and biology are relatively detailed, read the textbook carefully, and then do the relevant questions. If you need it, there is ** on the Internet, you can follow the teacher's explanation to learn. If you are English, first memorize the words in the textbook, after all, words are fundamental, do more reading, read more grammar.

Happy learning!

Regarding science, what you need to do is to understand the knowledge in the textbook thoroughly, and then you can become your own teacher. If you were a chemistry teacher, what would you do in class? Learning with this question is both easy and good to master this course.

Pro, comprehensible memory is most suitable, otherwise it can't be remembered.

Biochemistry has a large capacity, rapid progress, and a wide variety of reaction and molecular structures, which makes it difficult to learn. Therefore, how to learn biochemistry well is a concern of every medical student. This article shares some views on this issue for reference.

Step by step, note that biochemistry is not a morphological discipline. Its main task is to study the chemical composition of the human body, the new generation of radiation and the laws of its connection with functional activities. From chemical composition to metabolism to functional activity, there is an intrinsic and intrinsic connection between them.

In the case of protein chemistry, vitamins, enzymes, and substance metabolism, they are closely linked and have a strict logical relationship. Substance metabolism is the central content of biochemistry, and in order to learn this part, it is necessary to lay a good foundation in enzymology. Because enzymes are necessary for the metabolism of substances, almost all metabolic reactions in the human body must be catalyzed by enzymes to complete.

To learn enzymology, you must first learn protein chemistry and vitamins. Because the essence of enzymes is proteins, and vitamins (here referred to as B vitamins) are involved in the composition of coenzymes or prosthetic groups of enzymes. It can be seen from this that the study of biochemistry must follow its own inherent laws, from shallow to deep, from the surface to the inside, step by step.

If we take quotes out of context, reverse logic, and cut off internal connections, it can only be a detour and half the result. The biochemistry chapter, especially the material metabolism part, is very prominent.

As a compulsory course for biology students, biochemistry is difficult, but it is indeed a basic course that must be mastered. We all say that biochemistry is generally divided into two parts: the static part and the dynamic part.

The static part is mainly the basic characteristics of several types of biological macromolecules such as sugars, amino acids, proteins (enzymes), and nucleic acids. To learn this part of the knowledge, it is necessary to have a certain understanding of the basic knowledge of organic chemistry, otherwise there is no way to understand the structure, properties and functions of these molecules. The dynamic part is based on understanding the properties of several types of biomolecules in the static part, and studying their transformation process in the organism.

1. Develop the habit of pre-studying. Preview can enable you to recall previous knowledge, discover new problems, think about how to solve them, and bring problems that you can't understand to the class to better listen to the teacher's explanation. In this way, it can not only cultivate self-learning ability, but also improve the interest and effect of listening to lectures.

2. The habit of taking notes and sorting them out afterwards. As the content of the course grows and complexes, taking notes helps to get to the point. If the things you remember in class are more messy due to the tight time, then you should organize it after class to make it comprehensive and organized.

The process of sorting out is a very effective process, and it can also exercise one's ability to analyze and summarize. Therefore, you should get into the habit of organizing your notes.

3. The habit of reviewing after class. Because the pattern of forgetting is fast and then slow, what you just remember is forgotten most quickly in the first few hours, and then slower after two days. To consolidate what you have learned, you must review it in a timely manner, reinforce it, and form a habit.

4. The habit of solving problems by yourself. If you have difficulty learning, you should try to "give it a try" by yourself first. When you really can't solve it by yourself, you can complete it on your own under the guidance of your parents, taste the sweetness of victory, increase your confidence in yourself, and bravely meet the challenge of the next problem.

Reaction under the back focus, the tricarboxylic acid cycle and so on.

Personally, I think that the way to improve English scores is to do more exercises, after all, English is a liberal arts, it is based on accumulation, it is recommended to memorize and memorize the words of the college entrance examination first, which is very helpful for reading and comprehension of the content of the article, and listening can not be pulled down, listening to a set of listening every day, it is still very necessary.

Chemistry is mainly to do the questions carefully, many questions will be done but because not careful it is easy to make mistakes, of course, the basic skills must be solid, I am this year's college entrance examination candidate, the subject of the additional test is chemistry, this year I feel that it is necessary to sort out the wrong questions, nothing can be turned over.

There are many and scattered concepts to be memorized by creatures, so don't be too troublesome to turn over books and memorize more.

I wish you all the best in next year's college entrance examination!

It is necessary to accumulate day and night, learn more and remember more.
