However, the questions asked are not too difficult questions, they are basically exercises in books, if you have done exercises in advance, or really understand and master the content in the textbook before, these questions are quite easy.

The students sitting here can basically be said to be the pride of the sky, although it is said that after a few years of junior life, many people's minds have been a little wild, and the time in learning is far less than the original high school days, but except for a very small number of students who have embarked on the wrong path and have no intention of learning at all, most of the students will still take some time to master the basic content and knowledge in the textbooks, therefore, the teacher asked a few questions, basically, the students did not have any difficulty in answering.

"It seems that everyone still used hard work to learn, and they have a very solid grasp of the previous knowledge points, which I am very pleased with."

After asking a few questions, and reviewing the previous learning content and knowledge on those questions, and also explaining some ideas and methods for solving problems, the teacher also seemed to feel that the students were not very interested in explaining these questions, and there was no need, and they did not continue to talk about them, and closed the book directly.

Hearing the teacher's words, the students below immediately showed a smug look on their faces, no student does not like to be recognized and praised by the teacher, and the pride of these days is the same.

At the same time, when they heard what the teacher meant, they were not ready to continue talking about those questions, and these students were all relieved, most of them. I do think that talking about those questions. It didn't mean much, and some people had even dozed off.

"Still. Our course is very important for our major, especially for those who are interested in conducting research work in the future. ”

A smile appeared on the corner of the teacher's mouth, "Therefore, our mastery of this subject cannot be limited to the basic exercises in these textbooks. Instead, we should truly understand these knowledge points and master them more proficiently. ”

"Next, let's learn a few more comprehensive questions."

As the teacher spoke, he began to write on the blackboard.

Watching the teacher write on the blackboard, the students below immediately stared at the blackboard with full attention. It moves with the teacher's chalk writing.

When the teacher's writing was halfway through, many students had completely lost their previous ease on their faces. Even many people have frowned.

None of them were in math class on the first day, all the way from kindergarten. I passed the exam and was admitted to the current university. Or math college, math. It has definitely become the most important and familiar subject in their lives, and they clearly understand that this question must be the teacher's question, and next, I am afraid they will have to be tested.

"This first question, relatively speaking, is more comprehensive, if you can master it, then, for our course, for the knowledge points we talked about before, the explanation is really more comprehensive, below, give you five minutes, you think about it, see how to solve it, wait a minute, I will call a classmate to come up and answer it for you."

Sure enough, after writing the question, the teacher turned his head again, faced the students below, and spoke with a smile on his face.

Although they had already guessed it in their hearts just now, when the teacher said it himself, the students' hearts still tightened violently.

In particular, those students who had not yet found any ideas were extremely nervous, and they didn't care about anything else at all, just staring at the topic and trying to think about it.

Of course, there are also some scholarly characters who are not nervous at all, on the contrary, they have a little more expectation in their eyes, expecting the teacher to call them to answer questions, and when the time comes, they will go up and show their scholarly demeanor in front of the teacher.

By the time the teacher had copied the question, they had already found the idea.

Kong Guoming is one of them, but in his eyes, there is no expectation, he is not too interested in this kind of expression, anyway, for him, as the president of the student union of the academy, there is no shortage of opportunities to express himself, and most of the teachers in the entire academy basically know him, so there is no need to express himself like this.

After glancing at the topic, his gaze turned to Xiao Yi.

He didn't know if Xiao Yi had come up with this question, and if he hadn't figured it out, he still had to help Xiao Yi.

But it's a pity that when he looked at Xiao Yi, he only saw Xiao Yi's calm face, and he didn't have any expression, and he couldn't tell whether he had come up with it or not.

His lips squirmed slightly, Kong Guoming, who wanted to ask, finally decided not to ask anything, but after hesitating for a while, he still picked up the paper and pen, and wrote down the solution to this problem under a piece of paper, and secretly decided in his heart that if Xiao Yi needed it, he would hand it over.

Five minutes passed, and the teacher was still accurate about the time, and as soon as the time came, he immediately called a student, but to Kong Guoming's relief, the teacher did not call Xiao Yi, but called another guy who seemed to be a scholar.

This student quickly wrote the answer on the blackboard, and got the teacher's praise as he wished, and also got the envy of many students who didn't think of the solution, and at the same time, many students were relieved, and someone solved it, which means that the teacher will not call them.

After Xueba finished solving it, the teacher re-explained the question and gave two other answers that were different from Xueba.

The teacher's explanation is very wonderful and detailed, but it is not wordy, and he can always talk about the blind spots of most of the students, and the students below are all listening with relish, even if they have just thought of the answer, they are all listening with relish.

Xiao Yi also listened to the secret exclamation below, marveling at the power of this teacher, he also thought of two ways just now, but the teacher's third way of thinking was something he didn't expect, and this kind of thinking made him feel that he had benefited a lot, and gave him a new understanding of the previous knowledge.

"Okay, this question, that's it, I hope my explanation just now, can be a little helpful to everyone, next, let's look at another question, everyone is optimistic, it's still the same as just now, think about it for five minutes, and then find a classmate to answer."

After some explanation, the teacher soon moved on to the second question.

This time, this question is obviously much more difficult than the one just now, the question just now, just a synthesis of the previous knowledge, or at the basic level, this question, but has begun to have the meaning of improvement, began to contain some mathematical foundations and ideas.

When the question was finished, there were obviously a lot more frowning students, almost half of the classroom, frowning, even after five minutes, there were only a few people, and their brows were stretched, and even this time, Kong Guoming had no time to pay attention to whether Xiao Yi could answer it, because he himself didn't think of the idea until the teacher asked someone to answer the question.

And the teacher asked someone to answer, and it was no longer as smooth as the first question, and he directly called someone to answer, and called several people one after another, but they didn't answer.

It wasn't until I called a top student that I answered.

The teacher explained this question in more detail, but the students below did not listen as seriously as the first question, because many students could not keep up.

But for those who keep up, such as Xiao Yi, such as Kong Guoming and several other scholars, they listen to it more with relish, because the ideas contained in this question, as well as the understanding of knowledge, are at a higher level and more beneficial.

"Next, let's talk about the last question of the day, end today's lesson, and if anyone can answer it, I will give him a perfect score."

With the teacher's words, all the students were calm, their expressions became nervous, and their eyes were staring at the blackboard in front of them, especially those top students, who all showed extremely grim expressions on their faces.

After the second question just now, everyone has completely dared not underestimate the teacher's question.

The second question is already so difficult, and this third question, which was put down by the teacher and rewarded, should be so difficult?

Kong Guoming's expression also became extremely stern and nervous.

He doesn't care if he is usually full of points, but he has always been competitive and likes to challenge difficulties, and he still very much hopes that he can answer this question, at least, if the teacher calls him, he will not be ashamed.

As the teacher's chalk rustled, the third question soon appeared on the blackboard.

When the topic was completely presented in front of everyone, in the classroom, except for the teacher, everyone and their brows were tightly locked, and the expressions in everyone's eyes became extremely solemn.

Even Xiao Yi raised his eyebrows slightly.

There was a look of contemplation in his eyes.

For a while, he didn't even think of the idea at all.

Even, there is a feeling of not being able to start.

It can often be said that Xiao Yi's problem-solving habit is to figure out which knowledge point this question is to test at the moment he sees the question, and then slowly deduce it after knowing the other party's purpose...... But with the question in front of him, Xiao Yi felt as if he didn't know this question at all, and what knowledge points were being tested. (To be continued......)
