If you insist on what your child eats, will it activate the potential of the brain and easily become a college bully?

Foods rich in fatty acids: the brain's self-repair and metabolism will consume a large amount of fatty acids, especially omega-3 fatty acids, linoleic acid, etc.

You can eat more eggs. Eggs are also rich in lecithin, which can increase the release of acetylcholine, thus improving children's memory and acceptance ability. Moreover, eating 1 to 2 eggs a day can not only strengthen the body, but also make you energetic and concentrate in the process of learning.

Experiments prove that the beauty of eating eggs is that when the rich lecithin contained in the egg yolk is decomposed by enzymes, it can produce abundant acetylcholine, which will quickly reach the brain tissue when it enters the blood, which can enhance memory. Foreign studies have confirmed that eating 2 eggs a day can supply enough choline to the body, which is very beneficial to protect the brain and improve memory.

Chocolate Chocolate can quickly replenish energy. If you are taking an exam or working overtime, you can take some chocolate with you. Chocolate can help the body relieve fatigue and recover. Mustard Mustard is a seasoning, but its soking taste can still stimulate the taste nerve.

It should be noted that some children have poor memory, which makes parents more worried. What children need is to eat more nuts, fruits and vegetables. Fish is also a good source of protein. In daily life, they also need to supplement more RSHWHO brain memory-enhancing nutritional factors to increase children. The memory area of the son's brain.

What does it feel like to study in a class full of top students?

1. In the top student class, if you don't work hard, you will feel that you are quite strange. Then you work hard like a top student, which is very tiring. Later, you give up. After all, I don't need to chase such a high score, and it's not bad if you don't chase. In a word, in the top student class, the scum students will benefit, but it's useless if you don't learn it.

2. Here, the top students cheer each other together, form a learning community, activate their own energy together, go further together with a common purpose, and give up the time to rest and relax in order to bring more professional English classes to students. They are the creators of rural education and polish for children together. People of the stars.

3. This habit has been used until now. This is one of the feelings of being a top student in an ordinary school - rapidly expanding the interpersonal circle, especially the interpersonal circle of juniors, especially juniors.I enjoy the process of communicating with the opposite sex. It is very interesting to have different ways of thinking and different perspectives.

4. As a scumbag, if you are assent to a class full of top students, you will be abused and doubt yourself, and even feel that you are a rat shit in the class, and you will be so shameless.

How to prepare for English for the postgraduate entrance examination

Standing on the track of the postgraduate entrance examination, you have gradually moved forward. In addition to maintaining the study of English, the rest of the courses should also be prepared. Deepen your understanding through various textbooks, review materials, and reading online courses, and finally strengthen your memory by doing exercises. 5: As the golden period before the exam, the importance is self-evident.

Word book Words are the foundation of English learning. No matter what the English level of candidates is, they need to study words carefully. Some examinees said that there are many software for memorizing words on mobile phones, and it is a risky behavior to recite them directly with the mobile phone APP. It is a risky to break away from the word book.

Preparation in advance: Know the registration time, examination time, examination content and other important information of the postgraduate entrance examination in advance, so as to prepare enough before the exam.Set reasonable goals: according to your own actual situation and goals, set reasonable learning goals, and ensure that you work hard towards these goals every day.

Pay attention to basic knowledge. The review of the postgraduate entrance examination needs to pay attention to the mastery of basic knowledge. You should first strengthen the basic knowledge, and then start to review the key points and difficulties. Do questions and exercises. Doing questions is an important part of the postgraduate entrance examination review. You can test your mastery and improve your ability to solve problems by doing questions.

University of Chemistry dominant system nomenclature, can ethyl be used in position 1

1. According to the naming rules, write a simple group first, regardless of the size of the position (for example, 4-methyl-3-ethyl-also That's right, although 4 is bigger than 3). So it should be 2-methyl-3-ethyl-, and 3-ethyl-2methyl is incorrect.

2. You can try to write it. The first thing to understand is that the system nomenclature of hydrocarbons requires the longest carbon chain to be found as the main chain.

3. The naming of the system should be correctly applied. Bit 1 should not have methyl (-CH3), position 2 should not have ethyl (-CH2-CH3) 3, and position 3 should not have propyl (-CH2-CH2-CH3)...

4. There is another provision in the system nomenclature, that is, the simplest name can be used when there is no objection. Ethylbenzene is the simplest name for this substance, which will not intersect with the name of any substance, and is also the most commonly used name.

5. Ethylhexane. The main chain has 6 carbons, 2, 2, 3, 4, 5-pentamethylhexane. The main chain has 7 carbons, 2, 2, 3, 5-tetramethylheptane.The main chain has 5 carbons, 2, 2, 3-trimethylpentane. You should think carefully about the naming principles in the textbook. It should be relatively simple. I wish you success.

University bullies, how to review computer network application technology

1. "Computer network" review ideas Computer network" review ideas: "Computer network" according to OSI network reference The hierarchy of the model is reviewed in order, and the review focuses on "data link layer", "network layer", "transmission layer" and "application layer".

2. Efficient review of top students at the end of the term. First, sort out your own learning situation, based on the textbook, combined with your own notes, test papers, weak links, and existingProblems, etc., allocate time reasonably, and tackle and implement them little by little in a targeted and specific way.

3. Computer network basics. In fact, this part of the content is not commonly used in daily life. Unless you plan to engage in related industries in the future, it is recommended that you only need to pay attention to deepening your memory in the exam. There are really not many places applied at other times.

4. Review method of network technology: take the textbook as the main, take the syllabus as the outline, and eat the textbook thoroughly. The test questions must be based on the designated textbooks, not the teaching and auxiliary materials of a publishing house. Almost 100% of ordinary exam questions can be found in the textbook - of course, after multiple layers of synthesis and deepening.

What are the conditions for the conservation of mechanical energy? Is it related to elastic potential energy?

1. Conservation of mechanical energy. Only when gravity (or spring elasticity) works, the gravitational potential energy (or elastic potential energy) and kinetic energy of an object are transformed into each other, but the total mechanical energy remains unchanged. Conditions for the conservation of mechanical energy: (1) If an object is only subjected to gravity, the system composed of the object and the earth is the conservation of mechanical energy.

2. The conditions for conservation of mechanical energy are as follows: (1) Only the work done by the elasticity or gravity in the system. That is, ignoring the energy loss caused by friction, the conservation of mechanical energy is also an idealized physical model. ( 2) In a broad sense, the condition of mechanical energy conservation: the work done by forces other than gravity is zero.

3. Conservation conditions: only gravity or elasticity can work.(1) Work condition analysis method: When the transformation of kinetic energy and gravitational potential energy occurs, only gravity works. When the conversion of kinetic energy and elastic potential energy occurs, only elasticity does work, and other forces do not work, so that the mechanical energy of the system is constent.

4. The three conditions for the conservation of mechanical energy are only subject to the action of gravity, all kinds of throwing movements without considering air resistance, and the mechanical energy conservation of the object. Other forces, but other forces do not work, only gravity or elasticity do work.

5. The mechanical energy can be kept in the case of gravity or elasticity. Expression: Gravitational potential energy is the energy related to the position of the object, and the gravitational potential energy is relative.

6. The condition for the conservation of mechanical energy is: (1) Only the work done by the elasticity or gravity in the system. That is, ignoring the energy loss caused by friction, mechanical energy conservation is also an idealized physical model.(2) In a broad sense, the condition of conservation of mechanical energy: the work done by forces other than gravity is zero.
