It's better to imitate what is written on the Internet, we don't know where to start here.

Although it can't help you directly, I hope it can inspire you.

The Old Man and the Seagull Yes, I have.

Lecture first, use more**.

Hello teacher, I am a graduate of the 2010 college entrance examination with a score of 131 in the national first volume of Chinese, and now I am a student of Peking University.

I love languages for a number of reasons, but the main ones I think are interest, roots, mood, and even erudition, and I'm going to talk about that in more detail.

Interest: Not everyone has this, why? It is not easy to get a high score in the college entrance examination Chinese or about 100 points is very good And usually every time the big exam Chinese will not only not become a strong subject, but will become a subject for some students to pull points To sum up, many students do not like Chinese That's how the language is innocently abandoned and loses her beauty What should I do? We still have to go to the battlefield, we still have to learn well!

The key to cultivating interest is to make students willing to learn high school Chinese texts can be said to rise to the perspective of appreciation, you may wish to add more relevant background knowledge in each lecture, but to talk about it in a funny or relaxed way, it will definitely make students' eyes light up.

Foundation. Just like practicing martial arts, how to ensure that you get a high score in the basic knowledge questions of each exam? (Even guaranteed full marks) must be done in the usual effort It is recommended to buy some books such as the Chinese basic knowledge manual Let students read it every day when they read it in the morning You can dictate it before self-study in the evening About revising sick sentences or idioms practice must be done quantitatively every day You can do it in small amounts, but you must ensure that you do it every day.

Artistic conception. This is a step up Students who can experience the artistic conception of the poems are all high-score creators, especially in the appreciation of ancient poems and big reading, the master can guarantee that there are few deductions for cultivating students' artistic conception comprehension lies in reading aloud Reading aloud with emotion There is also the feeling of writing after reading Analyze more emotions and aesthetics Of course, this measure is limited to those students who you think have potential.

Learned. This is what most people are looking for, and if it is reflected in the students, it will only be reflected in the top Chinese students, including the love of Chinese classical literature, poetry, and even Chinese studies, and these top students may learn Chinese to better understand the classics and masterpieces on their bookshelf, then their attitude towards language learning will not need to be said.

I hope my advice will be useful to you, maybe but please be beneficial.

First of all, I would like to ask, has your child been selected by a professional sports school? Or was it just selected by the school varsity team?

I just read your supplement, and I personally think it can be practiced. The quality of teaching and teachers in the model middle school should not be bad, if your child also loves to learn, you usually pay attention to it, or ask a tutor when you go home, and the grades should not fall behind. Of course, it is possible that the school will put students with sports specialties in the same class, which may have an impact.

Your child is strong and does well in throwing, which is a good fit for basketball. And the talent can be seen at about fifteen years old. If you can't quit when the time comes, it shouldn't be delayed.

If that school also provides a good learning environment, then this is quite a good opportunity. If you practice it, you will have an advantage in the high school entrance examination and college entrance examination. I have a few sports students who have good grades, character and sports.

Personally, I think what the two upstairs said makes sense. If you want to play basketball, you must not only have height, but also have some talent and understanding, and professional basketball has higher requirements for talent or understanding. However, the NBA coach also said:

You can teach an athlete technique, but you can't teach an athlete how to grow taller. If your child is not very, very thin or has any diseases that affect exercise or are easily triggered by exercise, you can let him try it, after all, it is also a path, and it is possible to develop at least a hobby or specialty.

Also, although I don't understand, I don't think it's too late to be 12 years old. Basketball players don't seem to be able to be groomed from a young age. At that time, physical fitness, such as strength or something, was probably not enough.

If his talent doesn't meet the requirements of the sports school, the coach will naturally tell you. It should be possible to retire when the time comes. As for whether you can follow the path of professional basketball, the coach will naturally tell you.

I used to have a classmate who spent a few years in a sports school in primary school, and when he returned to those regular middle schools in the first year of junior high school, he still did well in the high school entrance examination. It's okay even after high school.

If your child is selected by a regular sports school. In terms of cultural classes, at this stage of junior high school, you should still be able to keep up with the teaching of ordinary middle school. However, according to the sports students and sports school students I know, I think that the closed training life of the sports school may have some impact on the children, and parents need to carry out multi-faceted education before going and during the process of returning home during the holidays.

If you can make it to the top league in basketball, it is naturally very promising, but the athletes who make it to the second division or other sports teams are not so clear.

One last note, since your child is only 12 years old, it is still time to grow up. However, playing basketball is more prone to injury, and if he really suffers a more serious injury, it may affect his entire basketball career and even daily life. Although the coach will take this seriously, it is good for you, as a parent, to know it.

Most of the above answers are based on advice from upstairs and what I know on my own. It's a good idea to ask a sports professional who isn't related to your child's sports team, as the information you may learn will be more comprehensive, accurate, and authoritative.
