One day, several students surrounded the librarian and asked, "Hey, how many books did Hua borrow?"
"Five books!" The librarian held out his hand.
"How about the big book" Function Theory "borrowed two days ago?"
"I have already returned it."
The students stared puzzled eyes: "This book will take at least ten days and a half. But it only took him a few nights to finish it. "
A classmate said, "If you study like him, you can either skim the flowers or skim them."
Another classmate said mysteriously, "I heard that he has a pair of cat eyes and can read at night."
"Oh, really?"
"Then let's go reconnaissance tonight."
That night, several students quietly came to China's window by moonlight. I saw him open the book, read it for a while, turn off the light, lie down, stand the book on his chest and stare at it straight. ...
The students watched the moon go through the treetops and climb the roof. At this time, Hua turned on the light and read the last few pages, with a satisfied smile on his face. He put the book aside, picked up another book and read it happily.
The students pushed open the door and rushed in. "Hey, China, how did you learn? Come on, don't be conservative! "
It turns out that Hua has a peculiar reading method. He can not only see with his eyes, but also read with his heart in the dark. He said: "Every time you read a book, you should grasp its central link, think independently and seek answers for yourself. If the conclusion is the same as that in the book, you don't have to recite it word for word. Because what you remember after learning is more profound than what you remember word for word. If knowledge is distance, then the method is speed. Continuous improvement of methods can speed up and shorten the distance. "
In this way, Hua swallowed the knowledge and nutrition in the treasure house of mathematics with his "direct method".
