He is plain, with a square face, wrapped in layers of blackened skin, and his face is full of wrinkles. Unusually big eyes and upturned flat nose are his most prominent features, which makes people think that he is smart at first glance, and it is indeed the case.
The reason why he is diligent is that he works late into the night again and again until he finishes it.
Every time in math class, Mr. Sun will tell you the selected exercises, and sometimes he will joke on the way: "Do you think Mr. Sun approves homework quickly?" At this time, there will always be a cry mixed with a smile in the class: "Ha ha ha, Mr. Sun, you are the fastest and most diligent!" " "Even if Mr. Sun doesn't ask, careful students will find that the teacher's eyes and dark circles have deepened, the wrinkles on his forehead that are" endless "have lengthened, and the original white eyes are covered with bloodshot eyes. Obviously, the teacher stayed up all night!
After class, if you have any questions, go to Mr. Sun. No matter when, he will always explain patiently. Sometimes, he will go to his poor classmates and ask them if they want to.
At that time, Mr. Sun's words were always so kind and calm, and his sharp eyes suddenly became very kind, just like our relatives!
Yes, this is our diligent teacher Sun, a diligent math teacher I love.
