Chapter VII

Gu Lu picked up the chalk and wrote down the formula line by line on a blank blackboard.

Solution 4: [lnx/x+1+1/x>lnx/x-1, i.e., lnx/x+1-lnx/x-1>k-1/x, i.e., k-11......]

The four blackboards were full of Gu Lu's writing.

He threw away the head of the chalk, rubbed his sore wrist, and said in a light tone, "The blackboard is so big, you can only write so much, in fact, there are fifteen solutions to this problem." There is no place to write the remaining three, and interested students can come directly to the office and ask me. ”

The students in the class smiled wryly.

Fifteen solutions......

Teacher Gu's behavior is really too brutal!

It's just an ordinary high school derivative problem, and Teacher Gu is so desperate that he comes up with fifteen postures to adjust it.

Shocked! A high school math teacher actually did such a heart-wrenching thing on a derivative problem!

You know, as pure as them, in the face of this kind of problem, but a posture is difficult to figure out!

Bi Qi in the first row looked up at Gu Lu with his eyes shining.

This new math teacher, very strong!

Bi Qi knows very well that high school math teachers, in terms of mathematics alone, may not be much higher than the top students in high school.

The teachers only have decades of teaching experience.

Just like the math teacher before him, he would make mistakes during the lecture, and a few times, Bizzy himself pointed it out "humbly".

However, Teacher Gu in front of him gave him a very different feeling.

Bizzie couldn't put into words.

However, he knew that Teacher Gu and other ordinary teachers were definitely not the same kind of people.

Bell bell bell ~~

The bell rings for the end of class.

Gu Lu carried a woven bag full of mobile phones, held a SLR, and after a brief arrangement of after-class tasks with his classmates, he returned to the office.

……………………

"Hey, Mr. Gu, there are a lot of things seized!"

Seeing Gu Lu coming in with a large bag, Zhou Haihong, who was on his desk, holding a thermos cup and taking a sip of it, said with a smile.

Gu Lu shrugged helplessly, "I can't do anything, as soon as I entered the classroom, I took out my mobile phones one by one to take pictures of me, and there was a female classmate named Su Ling, who was even more excessive, and directly took out the SLR!"

Zhou Haihong laughed, "Hahaha, this classmate who took the SLR is very spiritual!"

A young male teacher next to him who heard Gu Lu's conversation interjected, "I think it's because Teacher Gu, you're so handsome, those female students want to take a photo to commemorate it." ”

"Actually, I don't want to. Gu Lu rubbed his eyebrows, "I think the most wrong thing in my life is to have this face." But it can't be helped, it's innate, and I'm helpless!"

Young Male Teacher: "......"

"By the way, Mr. Gu, put the things down and I'll discuss something later. Zhou Haihong said.

Gu Lu nodded, put the confiscated mobile phone and digital camera in the drawer of the desk and locked them, and then came to Zhou Haihong's desk.

On the computer on Zhou Haihong's desk, Baduanjin's tutorial was playing.

"Move a chair and sit down. Zhou Haihong quietly turned off the video, cleared his throat, turned his chair slightly, and said, "Teacher Gu, I called here to discuss with you about next week's exam." ”

"Zhou Kao?" Gu Lu was stunned.

"Oh, yes, Teacher Gu, you just came here this year, you shouldn't know this. Zhou Haihong said suddenly, and then suddenly said, "Let me explain it to you." ”

Zhou Haihong and Gu Lu briefly explained.

Entering the third year of high school, in order to maintain the competitive state of the students, and let them exercise their mentality.

That is to say, treat every ordinary exam as a college entrance examination, and treat the college entrance examination as an ordinary ordinary exam!

For this reason, exams in the third year of high school are frequent.

There are not only single-subject examinations organized by single-subject teachers, but also all-subject examinations organized and arranged by the school.

Of course, there are also "weekly exams" specially prepared for key classes!

Weekly examinations refer to the all-subject examinations that only students in key classes take once a week.

The seventeenth and eighteenth key science classes have been conducting this kind of examination since the second half of the second semester of high school.

The questions of the weekly examination are freely written by the teachers of each subject.

Zhou Haihong is the mathematics teacher and class teacher of Class 17, and what he wants to discuss with Gu Lu this time is about the mathematics test paper of the first weekly exam in the third year of high school this week.

"My idea is that the two of us will each come up with a part, this time I will come out with the six big questions in the back, and you will make the choices and fill in the blanks in the front, no problem, right?" Zhou Haihong turned his head to look at Gu Lu.

After hesitating for a moment, Gu Lu slowly spoke, "Teacher Zhou, I haven't produced a test paper before, so I'm worried about ......"

Gu Lu was telling the truth, before this, he had never had a chance to get out of the test paper.

Zhou Haihong waved his hand and said with relief, "Teacher Gu, don't be so unconfident, there is not much difficulty in coming up with the question." If you can't do it, just find some questions from previous years and change them slightly. ”

"Anyway, it's just a non-formal weekly exam, don't have so much pressure, this time, it's just a practice. ”

Since Zhou Haihong said so, Gu Lu really has no reason to refuse.

He nodded heavily, and his tone was solemn, "Well, then I will definitely do my best!"

The test paper is out!

Gu Lu has been coveting this job for a long time, but he didn't expect that he would have such an opportunity just a few days after becoming a teacher.

In order to be worthy of this opportunity, Gu Lu decided that he would go all out.

Take out your full level and strive for a beautiful set of questions!
