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

At 8:00, the broadcast announced the start of the test time on time.

At this time, Lu Xingyao already had a general understanding of the test papers.

The difficulty of the eight questions to fill in the blanks is a standard ascending style, and the eighth question is the most difficult to fill in the blanks.

Given two positive integer columns and their conditions, then ask the possible value of the addition of these two positive integer columns.

When Lu Xingyao first looked at this topic, he thought it was okay, but he just started writing to calculate it, but found that there was a pit in it, and he couldn't figure it out after halfway through the calculation.

Lu Xingyao frowned and reviewed the question again.

The question was correct, and he read the conditions correctly, so why didn't he figure it out?

The tight exam time prevented him from thinking too much, and skipped to do the next three answer questions.

Missing a fill-in-the-blank question is only [-] points, but missing a solution question is at least [-] points, doubled directly.

He still knows which is more important.

Xu Mingxi, known as "Xu Shen", won the second prize in the last National Mathematics League, ranking 78th, and the top [-] entered the selection of the national training team. His ranking is only [-] points away from the top [-] .

In Xu Mingxi's view, he almost entered the national training team.

And at that time, he was only a freshman in high school.

Xu Mingxi is full of confidence in this year's provincial mathematics competition selection.

He believes that during his waiting time, his hard work will eventually become his achievement.

The news of the math competition registration came, and Xu Mingxi knew that his chance had come.

The sword pointing to the first place is Xu Mingxi's goal for participating in the provincial mathematics competition.

When seeing such a difficult problem as the eighth question of filling in the blanks, Xu Mingxi's first reaction was not entanglement or frowning, but joy.

As long as he solves such a difficult question, he will be able to widen the gap between others. Eight points are very important for the first place he wants to compete for.

Soon, when he was writing to calculate, he encountered the same problem as Lu Xingyao.

He couldn't figure it out.

How could it not be calculated?Xu Mingxi checked the conditions given in the question again, and there was nothing wrong.

Xu Mingxi didn't believe it, but: it was the perennial test literacy and the teacher's reminder not to stick to difficult problems before the test that made him look up and look at the time. It was 8:20, and only 10 minutes had passed.

He has seen three answers to the questions, which are the same routine questions as in previous years. The difficulty has not increased or decreased. For a person like him who almost entered the national competition, it should not be too simple.

What's more, his speed of answering questions is not slow.

Therefore, the temptation of eight points made Xu Mingxi continue to use different methods to calculate the eighth question of filling in the blanks.

Occasionally scratching my head, occasionally thinking hard, the thoughts finally came to my mind.

Just as Xu Mingxi was calculating seriously, Lu Xingyao had already finished the first answer question.

He cautiously went back to look at the argumentation process, methods, and answers.

correct.Lu Xingyao breathed a sigh of relief, and continued to solve the second problem.

Although he voluntarily gave up on the last question of the multiple-choice questions, he still had the idea of ​​returning to try after finishing all of them.

Answer the second question of the question, "In the space Cartesian coordinate system...", seeing these words, Lu Xingyao immediately recalled the drawing that Guan Lianyi repeatedly said. The coordinate system is drawn above.

It has to be said that drawing pictures is really helpful for this kind of questions. At least in Lu Xingyao's opinion, the conditions given by the questions are more intuitive.

After thinking carefully for a while, Lu Xingyao determined the approximate steps to solve the problem.

He did it more and more smoothly, as if he had entered a state of doing questions, and all the questions couldn't help him.

But the system task is like a needle, every time he finishes the problem, it will prick him and remind him to check.

After Lu Xingyao carefully checked, he checked the time habitually. It was 8:40, and there were still four or ten minutes before the end of the exam.

After looking at the third question, which was not too difficult, Lu Xingyao was full of energy. He hoped to go back and do the eighth question.

When Lu Xingyao embarked on the road to solve the third question, Xu Mingxi finally raised his head, sighed, and did not hide his joy on his face.

He did it, the eighth question of the multiple choice question, and he grabbed the eight points.

The first is expected.

Xu Mingxi checked his calculation process, yes, it seems that these eight points are destined to be pocketed by him.

It's just that when he looked at the big clock on the podium, Xu Mingxi was dumbfounded. It was 8:45, and there were... 35 minutes before the end of the exam.

"How could this happen?" Xu Mingxi couldn't believe it. In 35 minutes, he had to answer three questions. Even if he has the ability to reach the sky, he still needs time.

How can you solve three answer questions in more than half an hour?

Not only to look at the questions, but also to think, but also to calculate.

Xu Mingxi's gaffe attracted the invigilator. He knocked on Xu Mingxi's desk and said in a low voice, "Student, please keep quiet during the exam time."

Xu Mingxi had a complicated expression on his face, but the tight time did not allow him to think so much, so he hurriedly started to answer the questions.

Time passed by every minute and every second, and Lu Xingyao's problem-solving also came to an end.

As the hour hand pointed to nine and the minute hand pointed to twelve, Lu Xingyao finally stopped writing.

Except for the eighth question of filling in the blanks, the rest of the questions have been completed.

With a smile on the corner of Lu Xingyao's mouth, he began to turn his attention to the first question of filling in the blanks. He had to check it from beginning to end before going to the eighth question with confidence.

Checking is naturally not as difficult as solving the problem. I already know the method of solving the problem when I am doing the problem. Solving the problem is just to check whether the problem conditions are fully considered and whether the calculation process is wrong.

The minute hand on the clock slowly stopped at the number one position, and Lu Xingyao's inspection came to an end, and he couldn't wait to start solving this problem.

"The exam time is over, please put down your pen immediately and stop answering questions..."

Lu Xingyao stopped writing, and the broadcast came as scheduled.

But he has nothing to regret. After the eighth question is done, it doesn't matter whether he checks it or not. Anyway, he stops writing and reads the calculation in the middle. There is no mistake.

No matter how much you check, the method is still the same method, and the calculation process is still the same calculation process.

Different from Lu Xingyao's calmness and contentment, Xu Mingxi turned pale instantly after hearing the broadcast.

Sitting slumped on the chair, leaning against the back of the chair, Xu Mingxi's hands still couldn't stop shaking, and the cold sweat on his forehead slipped down drop by drop.

He is finished, and his topic has not yet been written.

At the end, he had only written half of the answer to the second question, and the third question hadn't been moved at all.

His first was hopeless.

There are [-] points for answering the third question. If you lose these [-] points, what is the first place?

Xu Mingxi has never felt so regretful, but no matter how much she regrets, it won't help.

After the invigilator collected the test papers and answer sheets, he let everyone out of the classroom.

The candidates walked out of the classroom one by one, but Xu Mingxi was still immersed in infinite regret.

Lu Xingyao also went out with the crowd. There was no need to pack up. The second exam will start soon, and the exam room is still in this classroom.

If it wasn't for solving personal problems, Lu Xingyao wouldn't necessarily be crowded with others.

There was a lot of voices outside the classroom, but it was harsh to Xu Mingxi's ears.

He angrily swept off the stationery on the table and shouted, "Get lost—"

Some candidates in the classroom who didn't want to go to the bathroom were taken aback. Seeing Xu Mingxi's crazy appearance, they didn't dare to say anything, and didn't dare to stay any longer, and ran out one after another.

After panting for a long time, Xu Mingxi recovered.

Looking at the scattered stationery on the ground, he went to pick it up one by one.

No, he didn't lose, there is still a second test, the second test is so difficult, he will definitely be able to get points to enter the national finals, he must enter the national competition.

When Lu Xingyao came back after releasing the memory, nothing seemed to happen in the classroom.

It's just so strange, there is only one person in the classroom, and why are the people in the corridor all quietly looking into the classroom, is there anything that cannot be seen openly?

Lu Xingyao thought about it, but didn't think about it, so he scratched his head and went in.
