Engineering drawing I rule you

Xie Huai returned home alone in the end, facing a table of steaming food, it was rare for him to lose his taste.In the evening, he also received a call from his mother.

Jiang Jin'an heard that they were alumni, so he came here to ask Qin Yiyan's opinion.Xie Huai didn't want to brag about him in front of his parents, and he didn't want to deliberately slander him, so he casually said that he didn't know him.

"Could it be that there is no one better than Qin Yiyan in the world?" He tried to find out.

"From Lao Xie's tone, it should be more or less the same." Jiang Jin'an sighed on the phone, "There is no way, who made you fail in engineering? There is no man to help you at home, so you can only rely on your son-in-law."

After talking for a long time, he blamed himself for the fault.Xie Huai got angry when he heard these yin and yang words, and hung up the phone when he didn't agree with each other.

Originally, he wanted to take this opportunity to inquire about his family affairs, but after thinking about it carefully, Xie Huai felt that he could wait until the day when he really opened his heart.

After sending Qin Yiyan away, his life was back on track. He got up in the morning to work in the library, went home to study at night, and sent him messages to ask him questions he didn't understand.

Xie Huai would ask him if he had eaten on time at first, but the reply he got was "um", and his attitude was extremely perfunctory.

After persisting for a few days, he still gave up.

Xie Huai always felt that after this incident, Qin Yiyan alienated himself, but he couldn't figure out what the problem was.

The final make-up exam was scheduled for the weekend of reporting and registration, and he was arranged alone in a small classroom, supervised by Yang Wenwei himself.After the test papers were handed out, Xie Huai read the questions first, and found that the question types were basically the same, which indeed met what they said was "equivalent to difficulty".

According to his habit, he would do the simple questions first, and then slowly think about the rest of the questions that he was not sure about.However, after looking at the questions without thinking for a long time, I only felt a headache. Xie Huai glanced at the wall clock, and handed in the paper when he felt that it was okay.

Yang Wenwei took the test paper and glanced at it from beginning to end: "Is it convenient to correct in person?"

"I don't care." Xie Huai shrugged and went outside the classroom to get his cell phone.As soon as he connected to the Internet, all kinds of news and notifications popped up. He originally thought that Qin Yiyan would come to care about him, but he searched through the dialog box and found no news from him, so he turned off the little red dot irritably.

After a while, Yang Wenwei shouted towards the door with a low voice: "Come in, the approval is done."

He opened the door and strode towards the podium: "How many minutes?"

"This kind of self-confidence is very similar to Xiao Qin." He handed the test paper to Xie Huai, "81 points, unfortunately, there is a question calculation error."

Anyway, just pass the exam.Xie Huai put on his schoolbag and stood still in front of him: "Can you clear me and Qin Yiyan's innocence now?"

"Of course, go to the academic affairs with me again, he should already be waiting for you there."

Xie Huai nodded and followed him to the administration building.Halfway through, Yang Wenwei couldn't help but say, "Xiao Xie, are you really just an ordinary teacher-student relationship?"

"Otherwise?" Xie Huai's tone was very impatient after being poked in his mind.

Yang Wenwei smiled deeply, revealing the creases at the corners of his eyes, looking like a kind middle-aged old man: "I'm happy for you, Xiao Qin has struggled for several years, and finally found a friend who suits him."

This sentence was like a needle piercing into Xie Huai's ear again.Walking to the door of the Academic Affairs Office, you can see a slender figure from the small window before opening the door.He followed into the office and stood beside Qin Yiyan secretly.

"The test paper has been approved, the test is good, and all the processes are fine."

"That's good." The teacher sitting in the middle looked up at them, "I'm sorry, Xiao Qin, I said something serious before. But it involves a matter of principle after all, and we must take it seriously."

"And Xie Huai, you should apologize to him." Qin Yiyan didn't seem surprised by this, took the test paper and scanned it from beginning to end, expressing the same emotion as Yang Wenwei, "Such a simple question is wrong."

"Indeed," the teacher smiled awkwardly, and turned his gaze to him, "Student Xie Huai, I apologize for the questioning last time."

But listening to his tone of voice, there was really no half sincerity.Xie Huai curled his lips and left the office by pulling his sleeve.

"Are you busy recently?"

"Well, I have to go out with my tutor next week."

"Okay," Xie Huai didn't know what to say, "Pay attention to your body."

"You too." Qin Yiyan turned to look at him seriously, "In the new semester, you have to study hard without my supervision."

But it's easier said than done.This semester, Xie Huai had to make up exams in Dawu, Engineering Chemistry, and Advanced Mathematics. The formulas and theorems alone made one's scalp tingle, and the three courses were retaken at the same time, so there was no time as much as last semester.

The first class was chemistry, Zhu Kecheng's low score drifted away, and he got up miserable to attend the class alone.At the beginning of the course, the enthusiasm of the students was high, and the classroom was already full of people.Xie Huai sat down by the back door, and took out a brand new textbook from his bag.

"I heard that it was reported, but I don't know how the teacher checked it, and I haven't responded yet."

"That's right, last year's final paper was so difficult, I wouldn't believe it."...

The classroom was stuffy and noisy, and some vague chatter could be vaguely heard, mixed in the noise with incomparable clarity.Xie Huai was so annoyed, he threw the book heavily on the table, and cleared his throat vigorously.

Someone looked back, and the rumors that started out of nowhere gradually disappeared.

He took out his phone from his bag again and found a message on WeChat.Kong Xinhui said that he took a seat in the first row and asked him if he would like to come to the front row to attend the class.

Xie Huai put down his mobile phone, looked over the dark heads, and found the empty seat directly below the podium, and was speechless in embarrassment for a while.

Even if you change your mind, you don't have to sit under the teacher's nose.He rejected the other party's kindness, opened the software to lock the phone, and prepared to listen to the class seriously.

The chemistry teacher was the one from last year, and Xie Huai had an impression of her.Unlike Yang Wenwei, she is a talkative female teacher who is very loose in giving marks at the end of the semester.But there will always be a few unlucky students in a class, and he didn't even get [-] points in the final exam, which is really too bad to make money.

After a few brief introductions, the teacher went straight to the topic and began to explain Chapter 3 ideal gases.Xie Huai didn't expect that she would jump and talk, and was soon bewildered by all kinds of equations and laws, and fell asleep on the table in despair.

I don't know how long it took, and there was a violent noise in my ears.He shook his body lazily, supported his heavy head, and looked up to see the teacher standing in the aisle, announcing that Jiang She was elected as the representative of the chemistry class and responsible for sending and receiving homework.

"Fuck, it's him again." Xie Huai came to his senses in an instant, cursing unabashedly.

After sleeping for most of the class, when the teacher explained the new knowledge points following the content of the previous class, he could no longer understand.

The same goes for physics and mathematics.Even if he insisted not to sleep and copied down the notes on the courseware verbatim, he still couldn't write homework after class.

The management of these courses is far less strict than that of Yang Wenwei. The teacher never rolls names in class, and will not record absences.Anyway, he didn't understand after listening to the class carefully. Under the strong sense of frustration, Xie Huai's interest in learning fell off a cliff. He sat in the back row every day and dozed off. Great sleep.

Kong Xinhui saw it and knew that it was not easy for him to study science, so she arranged a seminar room to help him make up lessons.Xie Huai didn't listen to the class, he looked at the formulas in the book and copied them mechanically, and wrote a question over and over for a long time.

"Squad leader, how to solve this equation?" He pondered for a long time, but he was still at a loss.

Kong Xinhui came over and took a look: "This question needs to be integrated by parts."

"Why are you talking about mathematics?"

"Many calculations in universities are inseparable from integrals." Kong Xinhui drew a circle on the stem of the question, "here is an lnx, do you remember its indefinite integral?"

Xie Huai shook his head blankly.Seeing this, Kong Xinhui moved the draft paper between the two of them, carefully analyzed the calculation, and wrote down every step of the calculation process in detail.

"can you understand?"

Xie Huai was confused when he heard it, but he was embarrassed to ask her to say it again, so he nodded in embarrassment.

"Wait, your question is wrong." Kong Xinhui saw the draft paper he had pressed down, "The frictional force of the bullet in the wooden block changes with the speed, so we should start with the momentum."

"Oh..." He replied dully, suddenly smiled wistfully, and lowered his head mockingly.

He felt that he was tearing down the east wall to make up for the west wall. He hadn't laid a good foundation since he was a child. How could he fill in the hole in a few days?

Probably seeing his loss, Kong Xinhui patted him on the shoulder and said comfortingly, "Don't be like this, isn't there still Senior Qin?"

"He has his own job and career, so how can he have so much time to care about me." Xie Huai turned his head away and said angrily, "I'm not the sun, so I can make him revolve around me."

After finishing speaking, he crumpled the draft paper again and packed his schoolbag in a hurry: "I'm going back, thank you."

"Wait!" Kong Xinhui failed to stop him, all words stuck in her throat.

Xie Huai walked out of the classroom with his head buried. The cool breeze of early spring penetrated into his cuffs head-on, chilling his bones for a while.

When it's warm and cold, it's the hardest thing to do.

The open space in front of the teaching building was open, and he looked up aimlessly, and saw the gray clouds and mist all over the sky, as if covered under a huge dome.

The sun only shows a halo, and nothing can be seen clearly.

Only then did he realize that it turned out that being controlled by others was also a kind of happiness.After working on the map, he could no longer find a teaching assistant who was as serious and responsible as Qin Yiyan.

But he couldn't selfishly occupy Qin Yiyan's time for his own passing.

Spring is cold.After the cold wind blew for a long time, Xie Huai gave up the idea of ​​studying and asked his seniors to copy the answers.After finishing his homework, he called his friends to go to the place where he often played to drink and karaoke, planning to have a good time.
