The teacher called the three students together and assigned the following question: How to make the white line longer?

The teacher was unhurried on the blackboard, measuring with a ruler, and drew three straight lines with white chalk.

The three students were then given red, yellow, and blue chalk. The three students stood in front of their respective white lines in contemplation.

The student with the red chalk wanted to write something on the blackboard several times, but hesitated to do nothing; The student with the yellow chalk was struggling to write, and the whole classroom could hear the sound of his dotted drawing on the blackboard; The student with the blue chalk thought for a while, drew two simple strokes on the blackboard, and then easily turned away from the podium.

When the second student finished painting and calligraphy, he also patted the dust on his hands and turned to get off the podium. The first student with the red chalk was at a loss, and wanted to see the answers of others, there was a picture of yellow chalk on the blackboard, and then in the distance was the small blue text that could not be seen clearly, the teacher did not urge, but he was secretly anxious, and gently drew a red trace with red chalk in the direction of the extension line at the end of the white line, and finally wiped the red trace with his hand in annoyance, and the tail end of the white line was also blurred by himself, extending radially to the direction of the extension line at the end of the line, the student turned around, lowered his head and walked off the podium with a red face.

The teacher asked the students with red chalk and yellow chalk to wait outside the classroom first, leaving the students with blue chalk alone.

After confirming that the two students had gone out, the teacher walked up to his answer sheet with the blue chalk students.

I saw the blue handwriting on the blackboard: a line segment with 1:1000 written on it. The teacher smiled and said, "You are very smart, you use the way of scale, give more meaning to a simple line, so that a line is instantly extended by 1,000 times, your thinking is very quick, and you are very good at learning and applying." The more you need to learn and the more you know, the more ways and means you will have to deal with problems. Life will be easy and convenient because of your wisdom, use your wisdom to make the white line longer......" and then said a lot of words of encouragement.

The "blue" student walks out of the classroom, lets the yellow chalk student walk into the classroom, and tells the red chalk student to keep waiting

"Blue" left happily. The teacher was standing in front of the yellow scroll, smiling

"Yellow" came to the side. On the blackboard is a drawing, the yellow chalk outlines a lively street, the drawing is very realistic, clearly showing the sense of distance from near to far, and the white line is at the nearest distance.

"That's a good drawing!" The teacher's heartfelt admiration,

"The figures, flowers, and vehicles in the painting are all very good, probably to deliberately show the length of this white line, and there are other short lines next to it to set off, and around the white line, small people, small roads, all set off the white line. You are using your own talent to extend the length of the white line, which not only embodies creativity, but also gives a sense of beauty, I believe that if there are more people like you in life, life will become colorful......" After the yellow and blue left, the red students walked into the classroom tremblingly, closed the classroom door, and were at a loss.

The teacher walked over, patted him on the shoulder, and then stopped him on the shoulder and led him to the blackboard.

"The easiest way to extend the white line is to continue to extend it with white chalk," said the teacher, holding the white chalk

A large hand above the "red" test paper draws a longer line,

"However, if you continue to paint white with red, yellow, blue, or other colors, it will no longer be a white line," said the teacher, using white chalk to make a mark on the long line that had just been drawn

"×", after a pause, the teacher said earnestly: "You are an honest and upright child, in this era of rapid change, there are too few people who can maintain their own standards, too many people in order to make themselves longer, more, they don't care if they become unrecognizable, let alone realize that after the change, they hate to cut off what they have gained" The teacher pointed heavily with the knuckles of his fingers

Where the "red student" wiped,

"Do you see the blur on the edge? Because of wiping, it is extended here, and it becomes blurred, this solid line has a feeling of infinite extension because of the blurring of the end, child, you must always be vigilant, maintain your own principles, and be an honest and honest person. "And then I took it again

"Red" observation

"Yellow" and

"Blue" works, smiling and saying, "However, thinking is infinite, and it is good to dabble in more knowledge and see more of the world." The above is purely the author's own imagination, just a fabricated story to express a certain thought.

Looking back on the past, I still feel that I was more sensitive and fragile when I was a student, and I hope to be valued and treated gently in my growth.

Let yourself be pampered and cared for, say goodbye to immaturity and dullness. The world is so big, maybe there is really such a careful and patient teacher somewhere who devotes their hearts and souls to the growth of the next generation silently.
