The tangle and depression of sophomores in high school. Please, help, hurry!! Yes!!! 15

First of all, adjust your mentality, the mentality of people in this time period is very important.

Stress is needed, but in moderation, don't be too anxious, exercise properly, run or something.

Find a goal and move down.

It's okay, don't worry, the more anxious you are, the more you can't find a way. Find a time to calm down and think about it, what do you want to do in the future, even if it's a short-term goal, it doesn't matter, at least you have a goal, but you have to achieve it one by one, math scores, it's not a day or two to improve first, the main thing is your previous knowledge, this thing is linked one by one. Find a time to understand all the knowledge points that you didn't know before, mainly to do more questions.

Your situation is very common, you must first calm down when encountering this situation, the main problem lies in yourself, as long as you clear this problem, in fact, you have nothing to be nervous about, you just want the college entrance examination is just an exam, who has not taken the exam, right, as long as you maintain a positive attitude, face every day happily, and try to do what you should do perfectly. No one can grasp the problem of getting up, haha It's mainly a habit. Persistence, persistence, persistence.

I'm also very bad at math, and I only do multiple-choice questions on exams, and I'm a liberal arts student. Don't be afraid, and don't care too much about others being better than you, you must know that people are more popular than others. To relax yourself, what you have to do is to surpass yourself and find your own breakthrough point.

Alas! The baby in the key high school really doesn't know what is tangled and depressed. 150 out of 60 in math, thank goodness for that.

Not to mention mathematics, there is no subject with more than 30% in all subjects (except politics)! I forgot to say, these days, it's really useless to read! It is recommended that the landlord jump out of the fire pit quickly!

Come out and start a business! In these days, entrepreneurship is king!

The average reaction rate is calculated as the difference between the starting and final concentrations over this period of time, divided by time. Since the image shows that the concentration of Co does not change during the two periods of -13, the average reaction rate is of course calculated to be 0. These two periods of time are indeed in equilibrium, and the forward and reverse reaction rates in the equilibrium state are equal and not equal to 0, which should refer to the instantaneous reaction rate.

To use an inappropriate analogy, if a person walks on a moving conveyor belt on a stationary ground, if the person walks in the opposite direction to the direction of the conveyor belt and the velocity is equal, then the speed of the person on the conveyor belt is 0 from the perspective of the person on the ground, that is, the equivalent of the ground. But the people on the conveyor belt are really walking.

Hope it helps you a little.

The vertical coordinate is the concentration, the abscissa is the time, you can see that 2-3 and 12-13 are flat, so v=0, 5-6 is up, so it is v>0, so this is the answer... Here is the average reaction rate, which is the experimental data, and nothing else is considered.

1. The third year of high school is a critical period for learning, and it is very important to concentrate in class. For self-study in after-class time, we should learn to sort out our own learning situation, based on textbooks, combined with our own notes, test papers, weak links, existing problems, etc., reasonably allocate time, and target and specific to overcome and implement little by little.

2. You can learn to master the ability of speed reading and memorization, and improve the efficiency of learning and review. Speed reading and memorization is an efficient learning and review method, and its training principle is to activate the potential of "brain and eye" and cultivate the formation of eye-brain direct reflection reading and learning mode. For the practice of speed reading memory, see the "Elite Special Whole Brain Speed Reading Memory Training Software", with software practice, more than an hour a day, a month's time, you can double the reading speed, memory, attention, thinking, comprehension, etc. will also be improved accordingly, and finally improve the efficiency of learning and review, and achieve good results.

If your reading and learning efficiency is low, you can practice it well.

3. Learn to integrate knowledge points. Classify the information you need to learn and the knowledge you need to master, and make it into a mind map or knowledge point card, which will make your brain and thinking clear and easy to remember, review, and master. At the same time, learn to connect new knowledge with what you have already learned, and constantly integrate and improve your knowledge system.

This promotes understanding and strengthens memory.

4. When doing problems, you should learn to reflect, classify, and sort out the corresponding solution ideas. When you encounter the wrong questions (carelessly do it wrong, you can't do it), it is best to collect these wrong questions, and each subject has an independent set of mistakes (the set of mistakes should be classified), and when we review before the exam, they are the key review objects to ensure that there are no more mistakes and points on the same questions.

I'm a freshman now... Seeing your situation, I also feel a little bit of empathy... The reasons for the poor management may be:

1. There is not enough time to do the questions, but you will know the questions that you haven't done, [I was like this at the beginning of my junior year of high school].

2. You do have too many knowledge points that you haven't mastered.

3. The examination and answering questions are not standardized, that is, the answering habits are not good.

First of all, you have to ask yourself, do you want to take the exam A or B, or specialty... You say you're "not motivated to study at all", then I'm going to ask you, June is coming soon. For the rest of the time... I suggest you do the question·· Especially the topic of finding a comprehensive ... Find a difficulty that suits you, involving more test points, and then do more, one is to improve your speed of doing questions, the other is to be familiar with the test points, knowledge points, and the sense of accomplishment of successfully completing the questions can give you motivation... Inspire you

And the last sentence I told you from the bottom of my heart: You have to rely on yourself for everything, and it is not very efficient for you to ask others at this time. I think you'll have a lot of tests after that... Mistakes are a very important wealth for you, and strive to make every mistake possible, do it right, do it standard... If you can complete 80%・I believe that 2A is no problem! Believe in yourself and come on!

Forever · · Never give up, especially if you're a man in your third year of high school!

ps: That's right·· Go out less and surf the Internet less during the New Year·· Gain time!

It is better to do it one by one, and every knowledge point of each subject must be done, and then you can do the comprehensive questions, otherwise you will feel annoyed when you look at the comprehensive questions, and you will not understand this and that you won't.

I am also a science student in my third year of high school, and my self-confidence has been hit by the fact that I have lost a lot of time studying culture due to studying art, and seeing that the grades of other students are improving, but I have been regressing. But I have chosen to cross the single-plank bridge of the college entrance examination, so I have to go down hard, be worthy of myself, and think about the hardships and tears I have endured in the past year. Don't give up, let's do it together!

*(1+10%) 4=12(10,000 hectares) 2. [7+(3 times the root number 5)] [7—(3 times the root number 5)] = b 2, b = 2 or - 2 (2), (a4 + a2b2)( b4 + a2b2 )=c 2, so c = ab (a 2 + b 2) or -ab (a 2 + b 2) 3, let the common ratio be a, then 243 = 9 * a 3, a = 3, so the middle two items are 27 and 81. (2) Let the common ratio be b, then 160 = 5 * b 5, b = 2, so the middle 4 terms are 80, 40, 20, 10

80,000 hectares of farmland will be returned annually, and the subsequent annual increase will be 10% over the previous year, so the following years will be 8 (1 + 10%) = 8 8 (1 + 10%) (1 + 10%) (1 + 10%) (1 + 10%) = 8 etcFor two numbers a,b, the proportional middle term is (ab) so the first sub-question a=7+3 5,b=7-3 5 So the proportional middle term is (ab)= (7+3 5)(7-3 5)= [7-(3 5)= 2 The second sub-question a=a 4+ab=a(a+b),b=b(a+b) So the proportional middle term is (ab)= ab(a+b)= ab (a+b) 3(1) Let the common ratio be q, insert 2 numbers, so 3 numbers are spaced in the middle, then 243=9*q 3, q=3, so the middle two items are 27 and 81.

2) Let the common ratio be q, then 160=5*q 5, q=2, so the middle 4 terms are 80, 40, 20, 10

First: Mathematics is to do more questions, it doesn't matter if you don't understand well in class, master the typical example problems, and ask the teacher if you don't let your classmates ask. Write down typical mistakes and make a correction book.

Second: Chemistry attention summary memory, not just do the questions can be improved, you need to learn the substances, equations classification and summary, assisted by a certain amount of questions.

Third: Science students are not good at geography in their freshman year, so if they can't do it, forget it, anyway, they don't take the college entrance examination.

Fourth: English should be at least a completion 3 readings a day, the words you don't know are found out, recorded, a month I guarantee that English will improve, once you can persist for more than half a year, you basically don't need to spend much time on English in the future.

Pure hand hitting, hope, thank you.

First of all, correct your mindset and don't say things that you are too stupid. Actually, you're just temporarily confused, not stupid. When I first entered high school, there is indeed a difference between it and junior high school, so I have to try my best to adjust this.

Secondly, the study of various disciplines, explore the methods by yourself, what suits you is the best, and it is useless for others to say that it is not suitable for you. It's best, take your time, don't be in a hurry, learn step by step, this is a gradual process, don't know how to ask the teacher more questions, don't be shy. It's just now, there's still time to learn, come on!

Don't waste time, do the questions, the sea of questions tactics! If you don't know how to do it, you will always see the answer, and the answer should be explained. When you can read all the questions and know what to do, and then you can get it right, that's it. Guangwai is not so difficult to examine, come on. Hang on.
