After handing over the system, the state forced me to study

We will soon enter the second week of training.

Due to the change of the time of the mathematics competition training class, teachers of several other competition subjects thought this time was reasonable, so they also changed accordingly.

This made Li Jiahao, who had known for a long time that Lu Xingyao would return home late, feel relieved again.

In the chemistry competition training class, he was repeatedly frustrated. Thanks to the drive of interest, he seldom missed the chemistry class, otherwise he would not understand the training content at all.

When returning home at night, Lu Xingyao heard him complain more than once, "Xingyao, the chemistry competition is more difficult than I imagined."

Lu Xingyao was very calm, "Then do you want to give up?"

"That's impossible." Li Jiahao replied firmly.

Look, he is such a person, like an unbeatable Xiaoqiang, once it is something he is interested in, it is very difficult for him to give up.

Lu Xingyao also knew that Li Jiahao was not a person who chose to give up because of difficulties.

Otherwise, he wouldn't have asked such a sentence.

On the first day of the second week of the training class, Guan Lianyi came with a stack of test papers just like the beginning.

Although he had learned and laid the groundwork for the first week, Lu Xingyao was still very nervous. He knew that he would improve, but he was not sure how much he would improve.

The test papers were passed on one by one, and they were quickly in Lu Xingyao's hands.

Lu Xingyao took down a test paper, handed the rest to the person three seats away, and began to look at the questions.

Unlike the dumbfounded eyes when he was doing the test paper for the first time, this time, Lu Xingyao's eyes were shining brightly.

He couldn't wait to do the topic.

Following Guan Lianyi's "start", Lu Xingyao calmed down and told himself to think calmly before starting to write.

Speaking knowledge in the first week does not mean not doing the questions, the explanation of knowledge is based on the basis of the questions.

Guan Lianyi also said long ago that they just didn't focus on doing the questions in the first week, but in private they still had to do the questions that they should do, and even after the training was over, Guan Lianyi would hand out papers for them to go back and do it by themselves.

So after a week, Lu Xingyao's growth can be described as unhappy.

The first question, in the space Cartesian coordinate system, suppose the equation of the saddle surface s is... Find the coordinates of point p on the saddle surface s, so that the straight lines passing through p and falling on the saddle surface s are all parallel to the plane.

This geometry question is not difficult. Lu Xingyao followed the steps given by Guan Lianyi, first drew a coordinate on the draft paper, and then listed it according to the conditions given in the question. He quickly found a solution.

He settled down and wrote down his answer.

Let the coordinates of point p to be obtained be p=(a, b, c), satisfying...

Lu Xingyao wrote very seriously, coupled with the fact that he was holding the pen tightly and writing heavily, the palm of his right hand was already covered with cold sweat, but he didn't dare to stop in the slightest.

It wasn't until he finished writing the first question that Lu Xingyao put down his pen, looked up at the time, and wiped the sweat from his palms.

Half an hour passed.

It seemed that his speed of doing the questions was still too slow, Lu Xingyao didn't dare to delay, so he quickly lowered his head and continued to read the questions.

Time passed slowly, and the clacking sound of writing in the classroom had already weakened, leaving only students in twos and threes still trying to write.

Guan Lianyi was sitting on the podium, and he could see all the students' movements at a glance.

He stood up and started his first patrol of the night.

Let's look at the first row first, the first one, Xu Chaoyang from Class [-], Grade [-], is also considered an old man who competes, and Grade [-] also participated in the math competition.

Now in the second year of high school, a year has passed, but there has been some progress.

After a brief look at Xu Chaoyang's geometry and algebra problems, it's not bad, the argument is fairly clear, and the scoring points are all stepped on.

Guan Lianyi nodded in satisfaction, and continued to read.

It's just that the next person didn't satisfy him. Guan Lianyi frowned and watched the argumentation process. He did the right thing, but the score points were either not written or written unclearly.

But Guan Lianyi didn't say anything more, just continued to walk in silence, but she didn't nod with satisfaction at the beginning.

The people who were seen were all trembling. They couldn't do the number theory and combination later, and now they were watched by Teacher Guan.

As a result, some people began to pretend to check the first two questions.

It's just that they don't know, this just makes it easier for Guan Lianyi to observe.

But not everyone noticed that Guan Lianyi began to inspect. Some people who were immersed in the difficulties of the questions and couldn't help themselves became irritable and frequently flipped through the test papers.

Guan Lianyi was tired of reading the questions, but the frequent sound of flipping through the test papers made him frown even more.

Frowning, he walked to the side of the student, and pressed the test paper he was about to turn over with one hand.

Sensing that something was wrong, the student slowly raised his head, and what he saw was the darkened face of Guan Lianyi.

He quickly lowered his head, not daring to make any other movements.

Guan Lianyi thought for a while, and simply picked up his test paper and read it. Anyway, this kid can't write well, and he is still making noise, so don't ask for the test paper, just show him.

Lu Xingyao didn't seem to have heard these noises. He was going crazy when he was doing the questions. In order to avoid running out of time, after reading the questions and sorting out the general answer methods and steps, he desperately started to rush.

He is responsible for the rattling sound of writing that still rings in the classroom.

Lu Xingyao couldn't take care of so much, staring at the number theory question in front of him, writing possible answer directions on the draft paper, his mind was spinning fast.

Guan Lianyi walked around to the side positions before turning back to the middle.

In the stop and go, he finally came to Lu Xingyao's side.

Stop, and what you see is the second side of the test paper.

Guan Lianyi identified it, and found that this is the dark horse who has risen recently, their sophomore Lu Xingyao.

Originally wanting to go because he couldn't see the first two questions, he stopped. Looking at what Lu Xingyao had written on the draft paper, Guan Lianyi shook his head, no, the solution of this question and number theory has nothing to do with these.

Guan Lianyi was a little disappointed. Just as she was about to walk away, she saw Lu Xingyao paused for a moment, then began to write again.

oh?Is this a way to be found?

Guan Lianyi was a little curious, so he didn't leave, just stood beside Lu Xingyao, watching him write.

Let b=mx, b+1=...

This proof method is much simpler than his own proof method.

Guan Lianyi's pupils were shocked. After this test question came out, he himself was the first to do it, but compared to Lu Xingyao's, his own was more complicated.

Guan Lianyi concealed his complicated heart, he didn't need to look behind, he already knew that Lu Xingyao could prove it.

He looked at the time, and there were still a few minutes, so he didn't look at it at all, and went straight back to the podium, waiting for the time to come.

Behind Lu Xingyao, there were three or four students who were not "taken care of" by Guan Lianyi. Seeing Guan Lianyi's movements and steps, he finally let go of his nervousness.

Thank you God Lu for attracting Teacher Guan's attention for so long.

Lu Xingyao wrote faster and more smoothly, and just wrote the last "make b(b+1) be a multiple of 2a", and shook his painful hand, when he was stunned by Guan Lianyi's "close the paper" .

He looked at the combination questions that hadn't moved, then looked at the time, and pursed his lips tightly.

He's not done.

He didn't even look at the subject of the combinatorial question.

Lu Xingyao was defeated by his own speed of doing the questions, and he made up his mind that he must practice by himself when he returned home.
