Open book is beneficial

When the early morning alarm clock rang in the corner of the narrow four-person bedroom, Cheng Zhou, who was lying sprawled on the upper bunk, hummed lightly.She closed her eyes, but reached under the pillow and fumbled wildly.Before the buzzing vibration under the pillow had time to spread, she skillfully grabbed the mobile phone that was wrapped in the mosquito net and almost fell off the bed, and turned off the alarm clock impatiently.

There was silence for about half a minute.

"Wake up! It's 07:30!" Half a minute later, Cheng Zhou sat up suddenly and rubbed his eyes.After that, there were turning and muttering in the dormitory one after another.

"Feifei, it's time to get up and learn English." Cheng Zhou jumped off the upper bunk in three steps and two steps, walked to the opposite bed with his slippers on, and poked the legs of the upper bunk that were exposed outside the curtain. TOEFL test."

Dissatisfied dreams came from the bed curtain, and then she turned over, and her exposed legs disappeared under the bed curtain.

Seeing that she couldn't wake up, she moved to the bed of the other two roommates.

"Qiqi, don't you go to the experimental class at [-] o'clock in the morning?"

"Junhan, you and the male god have an appointment for a morning run..."

Cheng Zhou's call was like a lullaby, and the roommates were still wandering in sweet dreams.

Hey, who swore last night that he would get up early with her and make progress together?He also begged her to wake them up one by one.Cheng Zhou realized that he had been let go again.

Washing and tidying up, drinking milk and filling oatmeal, Cheng Zhou listened to English listening with earphones, and raced against the clock to cherish the rare waking time in the morning.Seeing that it was getting late, she put on her backpack and went out the door.

On the morning of October when autumn is getting stronger, the sycamore trees on both sides of the path leading to the chemical building are brilliant and golden.Cheng Zhou sped along the path, leaving the crisp sound of footsteps crushing fallen leaves behind him.

Cheng Zhou's life has been muddled recently.After returning from the summer vacation in September, the atmosphere in the college suddenly became strange. The students around her were busy taking postgraduate entrance examinations, improving their grade points, and taking the IELTS and TOEFL exams.

The seniors and sisters all said that the freshman was confused, the sophomore was relaxed, the junior was busy, and the junior Cheng Zhou was busy and confused.After weeks of hesitating between going abroad, studying in graduate school, and looking for a job, she decided to try to apply for admission to graduate school first.

She is very fortunate that she did well in the college entrance examination and went to a key university like C University. The Department of Chemistry of University of C can achieve 20.00% of graduate admission rate every year. That is to say, students who plan to find a job or go abroad for further study, as long as their total score and grade ranking in the first three years are within 30.00%, there is a high probability of admission to graduate students. .

Cheng Zhou's grades were above average, and her grade point barely hovered around 30.00% in the past two years. She felt that the matter of postgraduate education was a bit hanging.If the grade points are not enough, extra points are used to make up for it. Cheng Zhou also understands the truth that this college student knows very well.She is not a social butterfly, and she can't play well in the club student union, and can't get these bonus points, so she has to find a way to participate in scientific research projects and post articles.It happened that Teacher Li Hui's research group in the college was recently recruiting undergraduates for a project, so she hurriedly mustered up the courage to send an email to Teacher Li.Unexpectedly, Teacher Li readily agreed, and made an appointment with her to have a face-to-face chat about the topic this morning.

Stopping in front of the 302 office of the chemical building, she tidied up her appearance again. After confirming the house number again and again, she took a deep breath and knocked on the office door.

"Please come in." A few seconds later, a clear but steady female voice came, and Cheng Zhou's heart skipped a beat.

The door of the office was ajar, and she pushed it open nervously.

In the deep corner of the big office, there is a separate desk facing the door. The computer monitor on the desk is on. The person sitting next to the desk is still hanging on the mouse at this moment. Looking at Cheng Zhou.

"Hello, senior! I'm Cheng Zhou, an undergraduate student in the Department of Chemistry. Teacher Li made an appointment with me today to discuss the subject, and asked me to wait for him in the graduate student's office first."

"Hello. You sit down first. Teacher Li will come over later." The senior sister pointed to an empty seat in front of Cheng Zhou, then turned her face back and looked at her computer seriously.

Cheng Zhou quickly nodded and sat down, took out his mobile phone from his jeans pocket, and pretended to check WeChat.Every time she felt embarrassed, she did the same to cover up her unnatural expressions and eyes and arms that didn't know where to put them.

After reviewing the WeChat chat records countless times, Cheng Zhou's neck almost broke.She raised her head secretly, and found that her senior was still staring at the computer screen intently, her thin and fair side face was well-defined, revealing a touch of alienation and indifference.

She was inexplicably a little scared.Before he had time to think about it, someone pushed the door behind him and walked in: "Sister Yazhen, good morning." The air was instantly filled with the aroma of buns and soy milk.

"Morning." The person in the corner raised his eyebrows slightly without even raising his head.

"Hey, is this the new little junior sister? She's so beautiful, where did you find Yazhen?" Another thieving female voice sounded.

Cheng Zhou quickly stood up: "Hello, two senior sisters! My name is Cheng Zhou, and I am an undergraduate student in the Department of Chemistry..."

The girl who spoke just now pushed Cheng Zhou back to her seat, and said with a smile, "I'm Zhou Yuning. I'm just in the second year of graduate school this year. That's your sister Wang Xiaonan. I'm in the first year of graduate school this year."

"Oh my god, I have a direct junior!" Wang Xiaonan exclaimed dancing, looking at Cheng Zhou expectantly, "Who did Teacher Li ask you to do the project with?"

"Ms. Li hasn't told me the detailed arrangement yet..."

"Don't think about it, it's definitely not you." Zhou Yuning looked at Wang Xiaonan with disgust, "Don't teach the school girl to be stupid."

"Shut up, who broke the instrument last week and let Sister Yazhen fix it all night?"

"Hey, Wang Xiaonan, I'm the last person to use the instrument, so it doesn't mean I broke it, okay? The instrument also has a service life."

Cheng Zhou smiled and looked at the two senior girls who were fighting, and his tense nerves could not help but relax.The awkward atmosphere in the room suddenly disappeared without a trace.

"Stop making trouble, both of you have breakfast quickly, don't let Teacher Li come over and see you later." A sentence suddenly floated from the corner interrupted the dispute between the two, and they immediately sat down obediently at their desks and devoured it up.

The organic laboratory is next door to the office, full of volatile and toxic reagents.In the eyes of Teacher Li, eating here is a big taboo.

"Yazhen, did Teacher Li come this morning?" Zhou Yuning didn't forget to ask while eating.

"Come here at 08:30."

A deafening wail suddenly erupted in the empty office.

"It's rare for us to wake up so early, why didn't we catch up with Mr. Li's random inspection..."

"But don't worry, as long as Wang Xiaosong is around, Teacher Li won't notice that we are being lazy."

"Your words are too mean, you are talking nonsense."

Cheng Zhou was also happy to hear that.The seniors are too cute.

After a while, Teacher Li came over.Li Hui is a well-known young professor in the college. He is young and promising, and has made great achievements in the field of semiconductor materials and chemistry.He was introduced from the United States four years ago and returned to China. Not long after the laboratory was set up, he achieved a number of research breakthroughs and achievements.

"Xiao Cheng, I kept you waiting for a long time. Come with me to the office now." Teacher Li walked in and inspected around. Zhou Yuning and Wang Xiaonan buried their heads down and were studying the documents hard at this time.

"By the way, Xiao Gu, you come too."

The person in the corner responded, picked up a green leather notebook and a pen, and walked past Cheng Zhou lightly, with a ponytail of dark hair swaying briskly behind him.

After the two left the office silently one after the other, Wang Xiaonan put down the documents in his hand and sighed, "Hey, my little coolie was snatched away by sister Yazhen just like that."

"I didn't think you were so useful as a coolie back then, but you were like an oil bottle." Zhou Yuning said sarcastically.

When Wang Xiaonan first joined the group, Li Hui assigned him to study under Zhou Yuning.It's just that after getting acquainted with each other, the two of them are not like teachers and sisters, but like good girlfriends who don't know each other.

"Get lost." Wang Xiaonan protested.

----------

"Xiao Gu, Xiao Cheng, you two sit wherever you want."

Leaning on the armchair, Li Hui looked down at a newly typed resume through the thick glasses.Cheng Zhou seldom interacts with teachers. Although he has been in college for more than two years, the "teacher phobia" engraved in his bones is still around the corner.She didn't even know where to put her feet at the moment.

Little Senior Sister Gu is obviously familiar with it, she sat silently on the side of the reception sofa in the office, and put the notebook on her lap.Seeing that Cheng Zhou didn't follow, she tapped the seat beside her with a pen to signal Cheng Zhou to come over.

Cheng Zhou seemed to have grasped at the straw, and hurried forward to sit down with his limbs straight, like a well-behaved kitten.

It was quiet in the narrow teacher's office, and the brief silence was extremely depressing.Cheng Zhou didn't dare to vent his anger until the ear-piercing sound of scraping paper was heard, and Li Hui put down the documents in his hand: "Xiao Cheng, I have read your resume, and you are still very good."

Cheng Zhou quickly responded awkwardly: "Thank you teacher."

"Then welcome you to our research group. This is Gu Yazhen, the senior sister in the group, and you will follow her to do the research from now on. Xiao Gu, let's get to know each other."

This... Cheng Zhou was suddenly a little reluctant.No matter which of the two senior sisters Zhou Yuning or Wang Xiaonan she met just now, she is very happy.As for the serious and cold senior in front of him... Cheng Zhou admitted that he was a little afraid of her.She had an ominous premonition that there were only two paths before her, one was to be labored to death, and the other was to be left alone.

Both of these situations are very common in university research groups.Undergraduates are temporary workers for their tutors, and few tutors will teach them by themselves, so the importance of brothers and sisters is reflected in this.If you meet a responsible senior brother or sister, the day of posting articles is just around the corner; if you encounter a bad one, you may end up working in vain.At this moment, Cheng Zhou was suffering and couldn't tell, and the retreat in his heart was beating loudly.

While thinking wildly, a WeChat QR code appeared in front of my eyes.Gu Yazhen held the phone in front of her, and said flatly, "Add a WeChat account."

Cheng Zhou was taken aback, then quickly took out his phone and scanned.

"Xiao Gu, I'll talk to you about Xiao Cheng's subject in a while, and you will be responsible for following up on this subject from now on." Li Hui continued to arrange.

"Okay." There was no emotion in Gu Yazhen's voice, as if she was used to it.Then she quickly changed the subject: "Ms. Li, I have already completed the reimbursement form for the materials purchased last time. Please sign it. There is also the report for tomorrow's meeting. I have some questions to discuss with you."

"Oh, okay. Xiao Cheng, if you have no doubts, you can go back to class first."

Cheng Zhou was relieved, thanked the teacher and senior sister and left quickly.

Before the thermodynamics class started in the afternoon, Cheng Zhou came to the classroom early and occupied three seats for his roommates in the front row.Just before the class bell rang, the three roommates entered the classroom one after another.

"Li Hui asked Gu Yazhen to take you?" Zhong Qi, who was sitting next to Cheng Zhou, opened her eyes wide in surprise.

"What Gu Yazhen? Who is Gu Yazhen?" Xie Feifei asked curiously.At this time, she had just straddled several legs and squeezed through a row of occupied seats with difficulty.

"She is a god of learning," Zhong Qi was a little excited, "When she was an undergraduate, she ranked first in the grade in our college for four years, and in the second year of Zhibo, she has published four articles in SCI District [-]."

In the second year of her Ph.D., she published four articles in top journals. Zhong Qi felt that this was simply her unattainable dream.

"And Gu Yazhen is very good-looking, the kind that kills both men and women."

"This is too powerful." Cheng Zhou wanted to cry but had no tears.Senior sister's icy face still kept appearing in her mind, and her thoughts of quitting became stronger.This is great, such an excellent senior, she probably thinks she is a fool.

"Such a good opportunity to hug the thigh, why are you so sad, are you out of your mind?" Chen Junhan added, "If I hadn't been busy dating the male god, I would have joined the group to do experiments a long time ago."

Zhong Qi: "That's right."

Xie Feifei: "Stupid not stupid."

Cheng Zhou: "..." Okay, okay, take a while to quit, let her think about it.Chen Junhan and the others are veterans who have been on campus for many years, and Cheng Zhou has no opinions, so Cheng Zhou will always listen to what they say.

"Okay, students, let's start class now." The angry voice of the old man who taught thermodynamics echoed in the classroom, and the lively communication in the classroom gradually cooled down.

Cheng Zhou quickly took out his notebook, and neatly copied several large characters on the projection: Thermodynamic Analysis of Chemical Process.

Zhong Qi glanced at Cheng Zhou's colorful notebook, lowered her head and joined Chen Junhan and Xie Feifei's army of playing mobile phones beside her.

After class, Cheng Zhou had time to check his phone.She looked at WeChat, Gu Yazhen's message box was at the top, so she couldn't help but click in and take a look.Cheng Zhou's WeChat name is Cheng Xiaozhou, and his profile picture is a cute orange cat.And Gu Yazhen's WeChat name is Gu Yazhen, which is really simple and rude.Cheng Zhou clicked on the big picture of Gu Yazhen's profile picture, and found that it was a pen sketch of a violin.There are no selfies in Gu Yazhen's circle of friends, but only classical music and folk songs shared, the frequency is once every six months.

Life in graduate school is really terrible, Cheng Zhou thought.

Cheng Zhou originally wanted to invite Senior Sister Gu to a meal to enhance the friendship between the senior and sisters, but before he could say anything, a message from Gu Yazhen popped up on WeChat.

Gu Yazhen: "This is an important document on organic semiconductor devices. You can study it carefully in the past few days. After reading it, we can exchange ideas with each other."

A PDF file with an English title is attached directly below the text.

Trembling, Cheng Zhou clicked on the PDF file and quickly dragged the page to the bottom. The Arabic numeral "18" was written under the dazzling English words.

Eighteen pages of professional English vocabulary, Cheng Zhou felt that his fear of his senior sister had increased to a higher level.
