Twenty idioms

A young associate professor of physics in a university lectures on quantum mechanics. The course has always been known for being difficult to understand, and many people skip classes.

The associate professor was very annoyed, and tried to call and spot-check occasionally, but there were still many people who took chances and took risks.

Later, the associate professor had no choice but to sigh dejectedly, and said, "Sure enough, the path of science is lonely. The closer you get to the top of the pyramid, the fewer people have the perseverance and determination to climb."

But what comforts him is that there is a tall and handsome male student who must always sit in the front row every class, always looking at him attentively, and his dark eyes flash a gleam of light from time to time when he listens to his lectures .

Every time the associate professor looks into his thirsty eyes, he feels motivated.

Later, in winter, there was heavy snow and strong wind, and the severe cold weather of minus [-] degrees. When the prescribed time came, almost no one was willing to climb out of the warm bed to attend difficult and difficult courses.So when the associate professor pushed open the door of the classroom with his frozen hands, he saw only an empty space.

He was standing on the podium in disappointment, with his head down, sorting out the handouts he had prepared all night, when there was a soft push on the door, the handsome male student entered the classroom, wiped off the snowflakes on the down jacket and scarf, and was blown away by the wind. A bright smile appeared on his flushed face, and he said, "Teacher, I'm not late today, am I?"

The associate professor suddenly felt his eye sockets moist.His voice was softer than ever before: "I'm not late, thank you today for being able to come to class despite such a heavy wind and snow." He thought for a while and asked, "I never asked your name, teacher at the end of the term You must remember to add points to your usual grades. It’s rare to see a student as smart and diligent as you. Many people complain that they don’t understand, so they simply don’t come. They should really learn from you—”

"Teacher——" the male student glanced at him cautiously, "Actually... I'm not from the Department of Physics, but a student from the School of International Relations next door. Teacher, I don't really understand what you're teaching. Every time I just want to come look at you."
