I remember when I was in elementary school, the TV at home was always on the verge of being scrapped. At that time, my parents didn't fix the TV, but put a radio on the desk.
At that time, I listened to Mr. Shan Tianfang's "Water Margin" while writing my homework, and when it was broadcast at 6:30 every night, I also started writing homework at 6:30 in the evening.
Half of the little ** book is finished, and my homework is also finished.
When I was in the fourth grade, I still maintained this habit, and at that time I listened to Teacher Shan Tianfang's "White Eyebrows", and I still remember it vividly when I think about it.
Although I used to listen to the old radio all the time, it didn't affect my homework, and I was able to finish my homework on time every day.
Even when I was in junior high school, whenever I went home, I liked to turn on the radio and listen and write my homework.
Sometimes, I don't know what I'm listening to, so I think that if I turn on the radio, I can quickly find the status of my homework.
But now if I write homework or read books, I don't play reviews or broadcasts anymore, because my thoughts are easily carried away.
If I really want to have some sound, I will choose to put some light **, which is more suitable for reading.
But to tell the truth, when I chose to put some light **, it was already when I felt tired after reading the book for a while, and subconsciously I actually wanted to rest.
My child is now in the second grade, and there is no situation of writing homework while listening.
For him, if he listens to ** and writes homework, it is easy to interfere with his thoughts, and at the same time, he has not developed such a habit.
He likes to listen to ** or children's stories while drawing and playing with toys, which is a habit formed as a child. 
When he draws, he puts his phone aside, chooses what he wants to listen to, and then finds what he wants to draw, and draws while listening.
Every time I listened to a song, I would sing along, and then the more I draw, the more I would get better, sometimes sitting at my desk and drawing for two hours without moving.
When he plays with toys, he likes to listen to children's stories, such as encyclopedias and detectives.
He'd heard some of them four or five times, and he knew what the next sentence was going to say, but he still listened. It's as if this is already the standard for the toys he wants to play with. 
Add**Note, no more than 140 words (optional) I have also seen this problem in a book before, it is that the author has always wanted to write homework and listen to ** is good, but in the end it was confirmed that the answer is not good. Listen to any type of **, whether you like it or not, whether you can understand the lyrics or not, whether you have lyrics or not will obviously damage our work performance.
The main thing is that these ** will contain a lot of attention, whether it is a certain note or a certain tune.
However, in real life, when we do some repetitive work or more artistic things, we will feel better and more efficient when we listen to it.
Because artistic creation often requires a lot of emotional input, and ** can drive emotions well.
But sometimes children choose to write homework and listen to **, not to improve efficiency, but more to make homework a happy thing.
When your child is doing homework, you can set a time and let your child rest appropriately.
Or when the child has been doing repetitive homework and wants to listen to it, then listen to it.
