Chen Zhou touched his head awkwardly. Just as he was thinking about how to explain, he saw the draft paper in Wang Xuehui's hand.

His eyes lit up, he quickly stood up, and took the draft paper from Wang Xuehui's hand.

Then, pointing to a question I wrote down last night, he said, "Teacher Wang, you are here. Please help me with this question. I haven't done it for a long time."

"No, I said how do you learn..."

Before Wang Xuehui finished speaking, Chen Zhou immediately interrupted: "Teacher Wang, if it were you, it would definitely be solved in minutes. I won't be able to do this. Come and show me?"

Wang Xuehui didn't say anything, just looked at Chen Zhou.

Chen Zhou immediately looked like he was studying and asked questions, and his fingers were still pointing at the question.

About ten seconds later, Wang Xuehui slowly spoke, "Show me the question."

Chen Zhou immediately handed over the draft paper, pointed to the question again, and said, "Teacher Wang, look, this question is just this."

Wang Xuehui looked at Chen Zhou again, then looked down at the title on the draft paper.

Seeing this, Chen Zhou breathed a little relieved and thought to himself: "I finally diverted my attention. Once the topic was finished, I will almost go back to school to attend class..."

There is no way, Wang Xuehui said something like you are a little bit arrogant. Chen Zhou didn't dare to be careless and could only take it seriously.

On the draft paper is a proof question of the limit of function. After Chen Zhou wrote it down last night, he didn't have time to do it, and he didn't know if it would be done.

Just as Wang Xuehui was looking at the topic, Chen Zhou also followed Wang Xuehui to read the topic.

The question is very simple, only one sentence.

"Prove lim(x→3)(x2-x-6)/(x-3)=5 according to the definition of function limits."

After reading the question, Wang Xuehui thought for a while, and then asked Chen Zhou: "Chen Zhou, what is the definition of the limit of function?"

Chen Zhou was a little slow and replied: "In a certain change of independent variables, if the corresponding function value is infinitely close to a certain certain number, then this determined number is called the limit of the function in this change process.

.”

"That's right, remember it's quite familiar." Wang Xuehui nodded, then picked up the pen on the table and began to explain while writing.

"First, you take any ε>0, and there is d=ε, so that all x is satisfied |x-3|

"Yes." Chen Zhou nodded, then glanced at Wang Xuehui.

Wang Xuehui also looked at Chen Zhou, hesitated slightly, but continued, "Then, there is (x2-x-6-5x15)/(x-3)x-3|＜d=ε, and the original question is proven.

.Did you understand?"

Chen Zhou subconsciously wanted to nod, and then quickly looked thoughtful and did not speak.

Wang Xuehui just looked at Chen Zhou like this. Usually, after he finished his questions, he would not disturb students' thinking.

This time, the same is true.

After waiting for a while, Chen Zhou felt that it seemed almost done, so he nodded slightly and said, "I understand, thank you teacher."

Seeing his appearance, Wang Xuehui couldn't say anything else. He just pointed at Chen Zhou and finally didn't finish his previous words.

At this time, the landlord called Wang Xuehui for dinner, Chen Zhou also packed the papers, and the two left the house together.

When Chen Zhou was about to leave his landlord's house and head to school, Wang Xuehui finally said: "Chen Zhou, learn advanced mathematics when you have time, don't delay your current study. The college entrance examination is imminent, and you...

.Do you understand?"

Chen Zhou looked back at Wang Xuehui, smiled, and immediately said: "Don't worry, teacher, I will definitely put the college entrance examination in the most important position."

After saying that, Chen Zhou quickly walked towards the school. He suddenly thought of a joke from Chen Haining and the others before, is the students in the eyes of the teacher different?

Chen Zhou now thinks that it may be a little different.

After this incident, Wang Xuehui did not talk to Chen Zhou alone.

Chen Zhou was still stably outputting his own firepower in the exam and was constantly sprinting forward with inaccurate progress.

Such stable achievements are probably one of the reasons why Wang Xuehui did not look for Chen Zhou.

As April passed, the countdown to the college entrance examination on the blackboard behind the classroom has been reduced to 50 days.

In about half a month, it will be the third mock exam before the exam.

And half a month is very fast for Chen Zhou, who is immersed in review plans and studying advanced mathematics.

Through this period of study, he has learned about a quarter of his advanced mathematics (Sixth Edition) volume in the first volume.

Although many of the knowledge points in the first volume were already familiar to Chen Zhou, he did not skip directly and studied them seriously again.

That is why Chen Zhou learned a little slowly.

Through this period of adjustment, Chen Zhou was able to control the amount of psychotropic agent well.

In fact, if he had utensils such as measuring cups, it would be more accurate. Unfortunately, conditions do not allow it.

During the month when I was hitting the medicine, Chen Zhou also discovered a situation.

Now he is drinking medicine every day to assist in his studies, but he never had the first time he had to take a day off.

This made Chen Zhou feel very strange. Did the body develop resistance to drugs? But the effective time of the drug has not been shortened?

Chen Zhou really couldn't figure it out, so he had to give up.

As time reaches the end of April, when the countdown to the college entrance examination on the blackboard is still 43 days left, the third model exam has been notified.

April 26 and 27.

For college entrance examination candidates, the third model is actually the last serious model exam in the true sense.

Although there is still the last four-model in late May, it is more like a warm-up match before the college entrance examination, and it is an adaptive and adjustable exam.

The main function is to give candidates a chance to train before the exam, see if the exam is in normal condition and whether they feel like a big exam, and at the same time reduce the difficulty of the questions and help candidates build confidence.

Therefore, candidates need to seize the opportunity of the third model, pass this exam, and promptly test the results of their own review, and check for omissions and fill in the gaps.

Therefore, further study your own learning status, enter the preparation state in advance, and adapt to the examination environment.

The third model is equivalent to a comprehensive physical examination and has great reference value.

No matter how good or bad the exam is, there is still a month to adjust.

Chen Zhou did not make any special preparations when facing this third-model exam.

After all, he has always attached great importance to big and small tests.

However, what Chen Zhou did not expect was that he visited again.

His exam room this time was the same as the Christmas exam, but he didn't know if Yang Yiyi was still next door.

On the morning of the 26th, I took Chinese language test and math test in the afternoon.

On the morning of the 27th, I took the comprehensive science exam and the afternoon of English exam.

According to Chen Zhou's habit, Chinese begins with composition.

After completing the composition, we will solve the previous objective questions.

Mathematics goes from choosing to filling in the blanks, to answering questions, and doing it one by one.

The comprehensive sciences and science solves the exam questions in the order of physics, chemistry and biology.

In English, you can do single-item fill-in-the-blanks first, which can be done before listening begins, and then listen to listening begins.

After listening, you will continue to do the questions from the cloze blanks.

On the afternoon of February 27, the last English exam.

Chen Zhou, who handed out the papers in advance, packed his backpack after walking out of the examination room, leaned against the desk outside the classroom, waiting for Yang Yiyi.
Chapter completed!
