The first is reading training. If you can only look at the key words and fully understand the author's intention, that is the first level.
The second is memory training. If you can read it once and repeat the main idea, it will basically become the second layer.
Third, recitation training, you can find some short poems and try to recite how many words you can read each time; Finally, watch it several times when it is completely good. How long can a successful cramming last? The less times you watch it, the longer you keep it, and this month is close to success.
I remember when I was in the first grade, my classmates tested me and let me watch Li Bai's Difficult to Go three times. I memorized it word for word, and now I can recite it completely for more than 30 years. Later at work, I was very good at sorting out and processing information, which benefited me a lot.
There are many books about reading and memory. You can read more, study hard and practice hard, and you will gain something.
If you practice, your reading will turn to the next page in two or three eyes, which is very cool.
