It feels like the brain is disconnected, and you can t judge right or wrong when you encounter somet

Hello, I'm glad to answer your doubts, and when you encounter things, you can't judge right and wrong well, this is a situation that everyone will encounter. Not everything you can judge correctly, so you don't need to dwell on whether your misjudgment is your own problem, but because there is no complete correct answer to these questions.

This is that people are sometimes not in a good state, but after sufficient rest and recuperation, it will also improve.

This is because you are not serious enough in your work, so you always feel that your brain is short-circuited, and you can't judge right from wrong when you encounter problems.

It may be that you are too tired, pay attention to rest, and let the cranial nerves relax. If you are too nervous, you will be more likely to react slowly.

The mental pressure is too much. Slowly adjust and adjust no matter what, the other party wants to maintain a good attitude. It's okay to take it slowly, exercise more.

Don't think about it so much. If it really hurts, go to the hospital for a check-up to see if there is any problem with the brain.

Do you have Alzheimer's? Go to the hospital immediately for a check-up and see what is going on? Then ask the doctor to prescribe some medicine for you, and I feel that this condition is Alzheimer's disease.

This should be that you haven't rested well, you can't concentrate, do things and take a good rest, there will be no big things.

Playing with the phone plays with the brain short circuit, just put the phone down!

In this way, it is necessary to recuperate, rest and pay attention, and the pressure is great.

Benefits of Internet Access for Secondary School Students:

Sending and receiving e-mails, playing games, consulting materials, making friends and chatting, and watching the news are the main purposes of middle school students surfing the Internet. The timeliness of news is especially evident on the Internet. Take the recent "9 11" incident in the United States as an example, not only can people understand the situation most quickly, but they can also post some posts to satisfy their desire to make a statement.

Some people have summarized the five major benefits of surfing the Internet: first, broaden your horizons, keep abreast of current affairs and news, and obtain all kinds of latest knowledge and information; Second, you can chat with netizens without any scruples, pour out your thoughts, reduce the burden of schoolwork, and relieve pressure; Third, you can post your own views and opinions on various issues in each BBS, and feel a great sense of accomplishment; Fourth, you can improve the level of your hobby; Fifth, it has become fashionable to make your own homepage, pass on your favorite ** information, open a discussion forum, post some posts, communicate with everyone, and feel really good to be a moderator yourself.

Every new thing comes with all kinds of worries, from the movies of the 20s to the later popularity** and video games, the focus of worries is nothing more than violence, pornography, decadence, etc. There is only a thin line between the advantages and the disadvantages, and it is often "a small miss, a thousand miles away", and the same is true for the Internet. Crossing the line of "pro" is "disadvantage".

We're in favor of surfing the Internet ourselves. As students, we not only need to relieve the pressure of studying, but also need to continuously replenish the spiritual food. It is undeniable that most of us go online to learn better, and think that the Internet is a great tool to support our studies.

In this sense, the benefits of secondary school students going online outweigh the disadvantages.

The Internet is illusory, progressive, and a part of contemporary people's lives, and the pros and cons of surfing the Internet are important to yourself.

For secondary school students to surf the Internet, we should not treat it as a flood of beasts, just because the Internet will bring some negative effects and choke on food. As students, we should naturally recognize the disadvantages of indulging in online entertainment, pay more attention to the truly valuable information on the Internet, contact the society through the Internet, and improve our ability to discern and think.

As a student, if you can use the Internet in a positive and healthy manner, you can reap the rewards.

I suggest you take a look at the book "The Source and Flow of Mathematics", by Zhang Shunyan, Higher Education Press. Frankly speaking, what you are currently learning can only be regarded as the surface of mathematics, mathematics is thinking, not ingenuity, and if you can understand this, your level is above your peers.

There's no need, do more questions, and you'll be successful

Be interested in mathematics, have confidence in yourself, practice a lot, and ask the teacher for advice if necessary, not only on the topic, but also on the method and attitude.

Every piece of knowledge has its own role to be learned. You go to the People's Education Network to find out, there may be.

Hehe, it's a foreigner upstairs?

You're amazing, you know trigonometric functions in the first year of junior high school!

But the exams are very basic now, so you should lay a solid foundation.

I'm a math teacher, so you can find me.

Did you learn trigonometry in the first year of junior high school?

Trigonometry is the focus of our college entrance examination now. But the difficulty has been reduced.

Among the various subjects, I am the most.

Bai likes to count.

du learned. So math is also learned.

Zhi is quite a good daoLet me give my opinion.

In fact, within the number. Learn this thing, and if you like it, you'll be able to learn it well.

So you don't have to think about whether you should learn it or not, you have to learn it when you should learn it. For example, this is a compulsory course in high school and an important knowledge, but if you can use it well now, it will be a good thing. However, I still don't agree with learning something too early that is not in the textbook that you are learning now.

All you have to do now is to learn the knowledge in your current textbooks and master the most basic knowledge. The reason why the textbook puts the shallow knowledge points in front is also reasonable, what do you think?

There's no need to learn functions in the first year of junior high school! If you use it, it means that you are learning too far ahead, and I don't think it will do any good. I used to be a math teacher, and I know the importance of functions, and you will not be able to live without them in the future. If you want to learn it now, let's get a thorough understanding of its definition.

Since everyone else is praising you, then I won't praise you. Learn more, there are benefits ... But if you don't learn what you should master, you won't be smart. As a word of advice, the most important thing is to lay a good foundation, or to master what you should learn first.

Awesome, I'm also a freshman in junior high school, but I don't even know trigonometric functions, admire

Seven Strategies for Math Learning.

2005-9-1 Science Review.

Learning strategies include not only the study of relevant problem-solving methods, but also psychological factors such as learning habits, learning awareness, learning attitudes and learning quality. Learning and researching learning strategies are of strategic significance for improving academic performance and related competencies and promoting self-development.

Strategy 1: Actively participate and collaborate with each other.

The participation mentioned here refers to the participation of teachers and students to communicate, inspire each other, cooperate with each other, continuously improve, discover knowledge on their own and acquire knowledge, which is mainly manifested in the experience of acquiring knowledge through active thinking in the classroom.

Strategy 2 Break it into parts and break it down individually.

No matter what kind of mathematical problem, it is often a reorganization of some knowledge. Therefore, in the face of a specific problem, it is necessary to grasp the overall understanding from a macro perspective, and then break down the problem into a number of sub-problems, break them into parts, and break them down individually.

Strategy 3: Excavate mathematical ideas and methods.

Mathematical thinking and methods are contained in the process of the occurrence, development and application of mathematical knowledge, which is the essence of mathematical knowledge and the bridge for the transformation of knowledge into ability. We must be good at exploring the mathematical ideas and methods contained in the mathematical problems themselves, and be able to use them to analyze and solve problems.

Strategy 4: If you want to advance and retreat first, conquer later.

At first glance, some math problems may seem confusing. However, if we can carefully observe the form of the problem, without changing the basic structure of the problem, retreat the problem to the simplest situation, and accumulate methods and experience to solve the simple situation, we can quickly solve the problem given in the same way.

Strategy 5: Extensive contacts and multi-directional attacks.

For the same mathematical problem, if you can think more and more from different angles and activate the source of thinking, you can often get a variety of different ways to solve the problem.

Strategy 6: Think rationally and have the courage to practice.

You have to think about everything, and the same is true for studying mathematics. Thinking should be profound, be good at observing things from the perspective of numbers and shapes, and ask questions with mathematical characteristics.

Strategy 7: Discover and create through research-based learning.

The fundamental difference between research learning and traditional receptive learning is that receptive learning generally solves problems with expected, standard, and unique answers, while research learning** has open-ended results. In research-based learning, it is more important to experience and experience this process of research and problem-solving than to obtain results.

Don't give up.

Let's continue learning in combination with the diagram.

Are you a very good student to study, and I am now taking the graduate school entrance examination in zhiweidao

Learning distress, my experience is beyond the outline of the things do not read, the teacher said the method is very important, although that may be cumbersome, but it is the basis for solving difficult problems, pay attention to the textbook, do more exercises, in addition to think more, more summary, I think it is okay to learn mathematics well, as for trigonometry, this part of the content is also very important, but I don't know if it is within the scope of your outline, if you learn the Olympiad should take a look, if not within the scope of the outline you have not learned the Olympiad, there is no need to read.

You have to work hard, ask your teachers or parents if you don't understand, as long as you work hard, you can succeed, you can't be lazy, you have to review the content of the day every day, you just believe that you can succeed.

Personality: People born on October 1 will get the highest position, not because they are ambitious or impatient; It's because they're far-sighted and capable. When they are in power, there is a lot of pressure on their hearts that is difficult for them to bear.

Most of their difficulties in life are focused on their careers. Often, they spend more than a decade climbing to the top only to find that it is not what they thought it would be, resulting in frustration and pain. Although they have achieved career success, their serious nature does not allow them to be happy because of their career achievements.

Career: People born on October 1 will encounter problems that they can't solve at work, and they can't tolerate them because of perfectionism. It's a problem that costs them a lot of energy and a lot of time, and it's not worth it.

In any case, they have an excellent performance in solving difficult problems.

Love: People born on this day will choose capable and decisive people as partners, and appearance is secondary. The most important thing is that the partner is able to assist them in fulfilling their career dreams.

Health: If they are really health-conscious, their health will not be a major problem, but if they are not health-conscious, their health will gradually decline. This is especially true of kidney damage caused by improper diet or mistaken medications.
