Do you understand Euclid today?

Lin Qianshu felt that the atmosphere in Class B was weird in the past few days. When he walked into the classroom recently, all the students were reciting words with their heads down, or reciting words or silent texts, even the one sitting next to the podium who liked to watch him secretly The boy also lowered his head and concentrated on brushing up the questions, ignoring the outside world at all.

Although Lin Qianshu didn't have any hobbies to attract attention, the people who had been paying attention to him suddenly stopped paying attention to him, which somehow made him think it was a little unusual.

After being ignored for another day, Lin Qianshu finally couldn't help it anymore, he turned his head and asked in a low voice Wang Siyu who was also holding a math textbook and was seriously doing the questions: "Student Wang, the last two days...everyone has been very serious. "

Wang Siyu raised her head when she heard the words: "Because the midterm exam is going to be on Thursday."

Midterm exams are coming? !Lin Qianshu almost jumped up from his seat.It's no wonder that everyone has no time to chat and play, and they are all anxious to hold Buddha's feet.

He remembered that he suddenly lost his memory at noon on the day of the monthly exam in September. He thought he was lucky to travel through time, and finally had to rely on a small note from Jiang Yizhi to pass the exam without any risk. Lin Qianshu suddenly felt that he had gone through a lot of vicissitudes.

The mid-term exam... I have to sit in the exam room again.

After class, Lin Qianshu walked to the other side of the stairs on a whim, just passing Class D.Compared with Class B, which has a strong learning atmosphere, there are obviously more people in Class D who are positive and optimistic, such as Radar, who jumped all the way to greet Lin Qianshu.

"Brother Lin! Brother Lin!" Rado twisted into a banner, and smiled to show Lin Qianshu the latest fidget spinner that he found near the elementary school, "This thief is strong, around the Inception space!"

Jiang Yixing took down the spinning top on his index finger with disgust: "Confiscated."

Lin Qianshu wanted to laugh, but also was curious: "Aren't you going to review?"

"Ah?" Radar blinked blankly, "Review what?"

For a moment, Lin Qianshu didn't know where to start complaining: "...the midterm exam."

"Oh," Radar showed a dazed expression, and then taught Lin Qianshu, "Old Gao said, the midterm exam is about your daily accumulation and exam mentality, so don't be too nervous."

Although he didn't know if there would be an astonishing answer like Jiang Yixing's "0 people" in Radar's monthly exam paper in September, Lin Qianshu was sure that his daily accumulation should be [-].

Forget it... What answer can you get by asking two people in the examination room No. 10 if they are nervous?Lin Qianshu sighed, and finally said to the two of them earnestly: "You should read more books."

Back in the office, Lin Qianshu mysteriously told Jiang Yizhi about his discovery: "Jiang Yizhi, the midterm exam is coming up this Thursday."

Jiang Yizhi took time out of his busy schedule to glance at Lin Qianshu: "It's written in this week's work schedule."

"That's right..." Lin Qianshu laughed awkwardly, concealing the fact that he didn't read the work arrangement with a guilty conscience.

Jiang Yizhi paused, turned his head to look at Lin Qianshu squarely, and hesitated for a second in his eyes: "With the recovery of your knowledge level, it is no problem to complete the simulation paper of the third year of high school. Are you... are you worried?"

Jiang Yizhi spoke very cryptically, but Lin Qianshu understood - Jiang Yizhi was asking himself if he wanted an answer for reassurance.Looking at Jiang Yixing's expression, Lin Qianshu knew how conflicted he was.

Although according to Lin Qianshu's current review progress, he only saw the compulsory fourth in the math book, but he decided not to pull the upright Teacher Jiang into doing bad things: "You don't need to pass me the answer, I can take the test myself. "

Jiang Yizhi nodded: "If you have a headache during the exam, just raise your hand and leave."

Lin Qianshu also nodded, and told Jiang Yi helplessly: "It's alright, alright, I really don't feel a headache."

——When the two went for a re-examination last week, the doctor said to Lin Qianshu after the examination: "The congestion dissipates very slowly, almost negligibly. If you have a sudden headache, you must pay attention to it and come to the hospital in time." From that day on, Jiang Yizhi paid close attention to Lin Qianshu's headache, and told him at least three or four times a day, which made Lin Qianshu's ears feel callused.

Hearing Lin Qianshu's assurance, Jiang Yizhi was still worried, and confirmed it several times before going back to work.

In a blink of an eye, the midterm exam came.The math test was scheduled from [-]:[-] p.m. to [-]:[-] p.m. on Thursday. This time it was a unified exam for all grades, so Jiang Yizhi and Lin Qianshu were not assigned the task of proctoring the math exam.

At 01:30 in the afternoon, Lin Qianshu was woken up from his nap by Jiang Yizhi, yawning and walking towards the examination room of the senior year with a pen in his hand.

On the way, the two met unexpectedly with a group of people from Class D, Senior One, who were walking back from the playground with a basketball in their hands.

Radar, who had always greeted Lin Qianshu enthusiastically, wanted to tuck his head into his neck at this moment, hiding behind a 1.9-meter boy, trying to let him cover his huge body.Jiang Yixing was very aggressive. When he saw his brother and Lin Qianshu approaching, he didn't dodge or dodge, and even stopped and waited for them to pass first.

Jiang Yizhi walked up to his younger brother and said calmly, "Going to play?"

"Yeah." Jiang Yixing stretched out his hand and twirled the basketball twice on his index finger.

"Brother Jiang confiscated my fidget spinner to show me that I have worked hard to practice my spinning skills..." Radar murmured in a low voice behind 1.9 meters.

Lin Qianshu originally thought that Jiang Yizhi would criticize Jiang Yixing for this issue, but Jiang Yizhi just nodded lightly and said "um" to show that he understood.

"Going home for dinner tonight?" Jiang Yizhi asked.

Jiang Yixing put away the basketball, and his tone seemed a bit casual: "I won't return, I will accompany Radar."

Radar thought tremblingly: Actually, he doesn't need to accompany him... But seeing Jiang Yixing's slightly warning eyes, he swallowed those words back to his stomach.

"The exam is over." Jiang Yixing threw the basketball to another classmate, "Let's go."

Jiang Yizhi said "Okay", then raised his legs and continued to walk forward.

Lin Qianshu hurriedly stepped behind him to keep up with Jiang Yizhi. When he passed by Jiang Yixing, he hesitated for a moment, slowed down and asked Jiang Yixing in a low voice: "If you are serious about math, at least you can enter the examination room No. 7 Bar?"

Jiang Yixing glanced at Lin Qianshu with a half-smile, but did not answer his question.

Lin Qianshu caught up with Jiang Yizhi, walked side by side with him towards the examination room of the third year of high school, and said to him as he walked, "You really don't have any academic requirements for your brother?" After observing this month, Lin Qianshu found that Jiang Yizhi The way they get along with Jiang Yixing can be summed up in the word "independence". Jiang Yizhi occasionally restrains Jiang Yixing, but most of the time Jiang Yizhi's educational attitude towards Jiang Yixing is "as long as he is alive".

"Xiaoxing has his own life," Jiang Yizhi's tone was still cold when talking about his younger brother, "I can restrain him temporarily, but I can't accompany him forever."

"When he needed me very much, I was not by his side," Jiang Yizhi said, "Now I am even less qualified to suddenly dictate his life."

Lin Qianshu was stunned, and for some reason remembered the "incompetent brother" that he jokingly said a few days ago when the two were sleeping in the same bed.Where was Jiang Yixing when he needed him most?Intuition told Lin Qianshu that the answer was not what he wanted to know.

But soon, the questions in Lin Qianshu's mind were replaced by the difficult problems on the test paper after the test paper was issued. He briefly browsed through all the questions on the test paper, and with the bottom line in his mind, he picked up his pen and was serious. Start answering questions.

This question is about the knowledge points of Compulsory [-]. This question is in the second unit of Compulsory [-]. After this question...Lin Qianshu did it one by one, he felt like an old chef who was tasting food in someone else's restaurant , Every time you eat a dish, you can taste the raw materials and methods of the dish.He did the questions one after another, moving his pen very fast.

After an unknown amount of time, Lin Qianshu put down his pen and breathed a sigh of relief.

Looking at the entire paper that was densely filled, Lin Qianshu felt a little bit of anticipation for the results of the math test for the first time in his heart.Such anticipation made him look up at Teacher Zhu who was invigilating the exam, and he couldn't help grinning brightly at Teacher Zhu as well.

Teacher Zhu touched his cheek subconsciously, and licked every tooth with his tongue, and then showed a suspicious look - why is this young man laughing at himself?

Lin Qianshu picked out a few difficult questions and checked them out. After a while, the bell rang for the end of the exam.He put down his pen and walked out of the examination room with Jiang Yizhi, and couldn't help but say to Jiang Yizhi, "I think I can score at least 140 on this paper."

Jiang Yizhi smiled, "I said, with your recovery level, it's no problem to complete a senior high school math paper." He paused, then continued: "Would you like to try to make a real paper for the big math competition?" ?”

Papers for college math competitions?Lin Qianshu felt his brain throbbing when he heard this term, he slowly raised his hand and made a cross in front of his chest: "No, thank you for your kindness."

"You really don't want to try?" Lin Qianshu could hardly hear a trace of regret in Jiang Yizhi's tone.

"No." Lin Qianshu shook his head firmly and refused, "I think we need to take one step at a time and carry out rehabilitation in a down-to-earth manner."

At least so far, he has done math problems for a month. Although Lin Qianshu can feel that his math level has indeed improved a lot compared to the freshman in high school, he still feels a bit nervous when he hears the words "do math problems". An inexplicable feeling of irritability and fear.This has nothing to do with mathematics ability, it is a dislike of mathematics accumulated over the years. Lin Qianshu couldn't figure out what method he had used in the past seven years to get rid of his irritability and fear, and suddenly fell in love with him. math.

In other words, Lin Qianshu couldn't understand why he chose to major in mathematics when he was in college, and even went to the United States to study a graduate degree in mathematics.
