High substitute teaching.

Professor Zhang Zhongyuan's class.

As soon as class started, Zhang Zhongyuan asked the students to hand in their homework first.

During the 11th Golden Week, he still assigned some after-class exercises.

In the matter of handing in his homework, Zhang Zhongyuan is still extremely serious.

Zhang Zhongyuan once said a very classic sentence in the first class: "You have to hand in the homework I assigned to you." Some students may say, "Teacher, you never read the homework I wrote, and you didn't even make a correction." ”

"But the teacher wants to tell you that it is my right not to read, and it is your responsibility not to write or not, and whether to hand it in or not. If you don't write or turn in your homework when I check it, you're in trouble. ”

"Even if you handed it over, maybe I didn't have time to read it. However, if you don't hand it in when I want to see it, you're really in trouble. ”

All the students who have taken Professor Zhang Zhongyuan's high substitute class are deeply impressed by this.

Therefore, as soon as Zhang Zhongyuan said that he would receive his homework, everyone was very active in handing in his homework.

is different from Wu Xiping's class style, Zhang Zhongyuan's class, he often quotes classics, completely stretches a knowledge point, kneades it flat, and displays it in front of you in the most direct way.

Let you not only know this knowledge point, but also let you understand the source of this knowledge point, as well as the derivation of this knowledge point.

Moreover, Zhang Zhongyuan does not like to engage in classroom testing, he likes to ask questions.

He put all the questions in class, and discussed with the students to solve the problems by asking them.

It is the teaching of a mathematical way of thinking.

Relatively speaking, Chen Zhou still prefers Zhang Zhongyuan's class.

Moreover, the reason why Chen Zhou put Gao Dai in the last study is also because Zhang Zhongyuan's class is very interesting, he wants to follow Zhang Zhongyuan's progress and finish this course, it is definitely not that he doesn't like this course.

If all the lessons are done by him by himself, then why do you need a teacher?

Throughout the high-level substitute class, Zhang Zhongyuan was always in the process of gushing lectures.

Chen Zhou followed Zhang Zhongyuan's train of thought and verified the knowledge he had learned in the higher generations.

At the end of the high school substitute class, Chen Zhou was left alone by Zhang Zhongyuan.

Zhang Zhongyuan asked, "Chen Zhou, how is Gao Daixue?"

Chen Zhou replied: "I'm still learning..."

Zhang Zhongyuan glanced at Chen Zhou and said, "I'm still studying, I remember you didn't say that the high generation is more difficult? But I waited for you for a vacation, and I still haven't seen you come to ask me?"

Chen Zhou was slightly stunned, and muttered in his heart: "I'll go... Professor Zhang, you don't have to be so serious..."

Seeing that Chen Zhou didn't speak, Zhang Zhongyuan said again: "If you don't ask me, then I can only treat you as a teacher." This is the topic I prepared for you, you can do it at noon, and give it to me in my office in the afternoon, I know you don't have classes in the afternoon. ”

As he spoke, Zhang Zhongyuan took out an A4 piece of paper and handed it to Chen Zhou.

Chen Zhou glanced at Zhang Zhongyuan, and then reached out to take the A4 paper, on which were 5 questions handwritten by Zhang Zhongyuan.

Chen Zhou glanced at it roughly, heh, it covers the knowledge points of the upper and lower volumes of the Gao Dynasty, and they are all comprehensive questions...

"Chen Zhou, then I'll be waiting for you in the office in the afternoon. Without giving Chen Zhou a chance to speak, Zhang Zhongyuan finished speaking, took the teaching materials, and walked outside the classroom.

Looking at Zhang Zhongyuan's back, Chen Zhou sighed softly, he didn't expect that he would have a day when he was forced to study by the professor...

Zhang Zhongyuan walked to the door of the classroom, turned back and asked, "My office, you know, right?"

Seeing that Chen Zhou nodded, Zhang Zhongyuan left satisfied.

Chen Zhou folded the A4 paper and put it away, left the classroom, and walked towards the Yanda cafeteria.

After having lunch with Yang Yiyi, he returned to the dormitory.

These 5 questions, let's solve them quickly...

In the dormitory, Li Li was not there, Zhao Qiqi and Zhu Mingli were lying on the bed chatting, and both of them had the habit of taking a nap.

Seeing Chen Zhou coming back, Zhao Qiqi immediately sat up from the bed and asked, "Chen Zhou, why did Professor Zhang keep you?"

Chen Zhou took out the folded A4 paper, handed it to him, and said, "Leave me homework after class." ”

Zhao Qiqi opened the A4 paper curiously, and Zhu Mingli also got up from the bed and came over.

The two looked at it for a while, and then Zhao Qiqi turned his head to look at Zhu Mingli: "Will you?"

Zhu Mingli shook his head: "The first two questions will be understood, and the latter ones will be a little incomprehensible, will you?"

Zhao Qiqi also shook his head: "Me too." ”

The two looked up at Chen Zhou at the same time and asked, "Will you?"

Chen Zhou replied: "Forget it..."

Zhao Qiqi handed the A4 paper back to Chen Zhou: "What does it mean?"

"It can be made, but I have only finished reading the textbooks of the high generation, and I haven't completely understood it. Chen Zhou took back the A4 paper, walked to the desk and sat down, ready to solve the problem.

Zhao Qiqi and Zhu Mingli glanced at each other, also got up and walked to the desk and sat down, each took out the senior generation textbook, and prepared to study on their own.

Chen Zhou glanced at the two of them strangely: "Why did you get up?"

Zhu Mingli: "I'm ready to quit the habit of napping. ”

Zhao Qiqi: "Me too, Gan, you and Li Li are putting too much pressure on people, especially you." ”

Chen Zhou: "......"

Chen Zhou solved all five questions, which took a total of two and a half hours.

Looking at the process of solving the problem with two pieces of scratch paper, Chen Zhou also sighed that it was not easy...

He checked the scratch paper again, and after confirming that there were no mistakes, he got up and packed up his things and prepared to find Zhang Zhongyuan.

Waiting for Chen Zhou to leave the dormitory, Zhao Qiqi turned his head and asked Zhu Mingli: "Didn't he say that he wanted time?"

Zhu Mingli glanced at the time and replied, "It took him two and a half hours..."

The two looked at each other, then lowered their heads and continued to read.

3:00 p.m.

Chen Zhou came to Zhang Zhongyuan's office.

After knocking on the door, he heard a call to come in, and Chen Zhou pushed the door in.

Zhang Zhongyuan's office has a total of 5 desks, in addition to Zhang Zhongyuan's, there are also graduate students and teaching assistants he brings.

It's just that Chen Zhou didn't see anyone else, and Zhang Zhongyuan was the only one in the office.

Zhang Zhongyuan was sitting behind his desk, bowing his head and writing something.

Hearing the sound of the door opening, he glanced up and saw that it was Chen Zhou, so he asked directly, "Have you handed in your homework?"

"Yes, Professor. Chen Zhou took out the A4 paper and handed it to Zhang Zhongyuan along with the two pieces of scratch paper full of answers.

Zhang Zhongyuan stopped the pen in his hand and took the scratch paper and looked at it.

Looking at it, Chen Zhou found that he had changed his posture, and the person was leaning back on the chair.

After waiting for a while, Zhang Zhongyuan put down the scratch paper in his hand, looked at Chen Zhou, and tapped his fingers lightly on the desk, but did not speak.

Chen Zhou was a little inexplicable, and he simply asked, "Professor Zhang, is there any problem with solving the problem?"

Zhang Zhongyuan replied: "No problem, all 5 questions are done correctly, and the solution ideas are also very smooth." ”

Chen Zhou: "Then why are you looking at me like this?"

Zhang Zhongyuan: "It's nothing, I just think of my younger self." ”

Chen Zhou: "???"

Zhang Zhongyuan thought for a while, and then said, "Are you my teaching assistant?"
