"Not yet!" The girl's eyes widened. "If you don't leave, I'll have to call security!"

Said, a hand has taken out the mobile phone, a call to call the posture.

She was so fierce that she didn't give Xuejiao a chance to talk.

"What's the matter?" At this time, a little old voice came from the side.

Two people are a Leng, suddenly suddenly suddenly turn back.

"Mr. Tan, you are back..." Elder martial sister is very respectful, quite different from the attitude just now.

Snow Jiao also covered to see Professor Tan's excitement, clever way: "teacher Tan, hello."

"I heard Xu Jing's voice all the way. What's the matter?" Professor Tan asked, in fact, when he just came over, he had already heard almost.

The girl Xu Jing stepped forward: "Miss Tan, this girl is not from our school. Come to us..."

Miss Tan waved and interrupted her.

"I asked her to come. After that, she will be your younger sister. She just finished the college entrance examination this year."

Xu Jing was shocked and looked at the snow bamboo in disbelief.

Just after the college entrance examination, it is reasonable to say that the admission notice has not come down, so you came to study with Professor Tan?

Related households?

It's impossible. Professor Tan is upright. He can't accept any relationship.

Xu Jing was confused for a moment and looked at them blankly.

Professor Tan turned his head and looked at Xuejiao and said with a smile: "Gu Xuejiao, this is your elder martial sister Xu Jing. She has a strong strength, but she has a bad temper."

Gu Xuejiao!

Xu Jing's pupil shrinks and looks at her in disbelief.

This man is Gu Xuejiao!

For a moment, Xu Jing's head went down and wanted to go straight down.

Xuejiao smiles, and her tone is joking: "I see Elder martial sister, please take care of me gently in the future

Xu Jing:

His head was lower, and he wanted to get to the ground.

"Xu Jing, you still need to pay attention to some, at least ask clearly." Professor Tan's words are not painful, just such a light sentence, let Xu Jing's face red, heart pounding.

But she was also a little relieved. Fortunately, Gu Xuejiao was just joking. If she complained, she would really leave a bad impression on Mr. Tan!

Their voices were not big or small. People in 305 also heard Professor Tan's criticism of Xu Jing. They all stopped writing and listened with ears up.

"Yes..." When Xu Jing vomited out these two words, his neck became red.

Professor Tan waved: "OK, Gu Xuejiao will go to the office with me. Xu Jing, you can clean up a table and come out. She will follow you for the time being and help you with the project."

"Good." Xu Jing has a tight scalp.

Professor Tan nodded with a smile. In fact, he had some considerations. There were not many girls in his team. Xuejiao was a little girl. It was better to follow the elder martial sister.

Although Xu Jing has a bad temper, he is not bad at all. He is a straightforward man.

At present, his team has only two undergraduates, Xu Jing and Zheng Jiakun. Occasionally, when the project is busy, some undergraduates will be transferred to help.

Zheng Jiakun is very useful, so most of the time, Xu Jing is in the position of leading undergraduates. She is serious and can control students

But there are also many disadvantages, but he does not have a more suitable person, but Xu Jing is also a senior

Professor Tan put his eyes on the snow bamboo beside him and shook his head in his heart.

This girl is still too young. If you want to manage other people, you have to be a sophomore or a junior at least, and It's not necessarily suitable, alas.

No one knew what he was thinking. He just said, "let's go."

Xuejiao smiles at Xu Jing and immediately follows Professor Tan into the office.

Xu Jing stands in place, and her scalp is still numb.

It was teacher Tan who called over!

She just really lost face!

For a moment, she walked stiffly into 305.

These people just heard about it, but they didn't know who was coming.

"Elder martial sister, who is coming?" A sophomore from the mathematics department asked.

Xu Jing frowned and was embarrassed to lose face in front of her younger brothers and sisters.

But she was still serious and said, "Mr. Tan's office is going to be a newcomer, an undergraduate."

At present, the office is full of undergraduate students who have come to help, and all of them immediately look up.

A new person is not the same as a helper.

Help people to help hand this help is to leave, for example, Mr. Tan is currently lack of a few good at calculus, find a few good at calculus to help, busy a few days to withdraw.Next time you want to come, you have to wait for other opportunities.

But it's not the same to have a new person, especially to make a table available, which means that she can always be here.

As long as she has time and needs, she can do chores for every project.

There is a boy frown, he is a freshman this year, the beginning of school will be promoted to sophomore.

"Who is it? How old are you? "

"New man, new in September." After Xu Jing finished, he was shocked.

She felt better and could not be stimulated by herself alone!

"How could it be? Isn't it true that the freshmen haven't even come down with the admission notice? "

"Yes, and what does the newcomer know? Counting or advanced generation? "

"How could it be?"

The more active one asked Xu Jing in a low voice: "elder martial sister Are they related? "

Xu Jing took a deep breath and said, "you may have heard of this person. It was reprinted to the post bar a few days ago."

"Who?"

"Gu Xuejiao." Xu Jing slowly spits out the name.

"……"

That's the first prize in mathematics last year. Who's the number one in 731 this year?

This was pulled into the team by Mr. tan?

Not afraid to be a bookworm who can only read?

All of a sudden, the whole group is in doubt.

……

Xuejiao sits opposite Professor Tan with a computer on the desk and a bookshelf full of books related to mathematics.

When you enter the door, there is a big table beside the door. There is a big diagram on it. It is a structural diagram.

Snow water bamboo just a casual glance, did not dare to stare at.

Congratulations on your success in the college entrance examination Professor Tan congratulated her with a smile.

Xuejiao embarrassed to scratch his head: "thank you, teacher."

Last year, I hope you can enjoy it with me. Xu Jing cleared a table for you. Although the college entrance examination is over, I hope you don't relax. If you slack off and can't keep up with the progress, I can't let you follow the team any more. Do you understand? " Professor Tan was very serious when he said this.

Xuejiao knows what he means That is, you should pay close attention to your study, and then pay attention to study in the team. If you can't go up at the same time, you should leave the team and study hard.

She looked at the teacher in a firm and serious voice: "yes, I'll keep up."

Professor Tan relaxed his face and laughed again: "then you should learn from your elder sister Xu Jing for a few days and do odd jobs for them. Your theoretical knowledge is not enough, so you can't help much for the time being."

Xuejiao nodded and agreed, "OK."

Then they talked about some questions about coming in early.

Finally, Professor Tan said, "go ahead. I hope you choose Tsinghua University, which is the most correct decision you have made."

Xuejiao smiles with a bright light in her eyes

"Yes."

She's already moving towards her goal.

……

When Xuejiao reaches 305, the others are gone, as long as Xu Jing is still there.

She feels sensitively that Xu Jing is waiting for her.

"You're here. Are you going to dinner?" Xu Jing really asked.

Snow water bamboo nods, smile: "good."

Eating together is also a process of reconciliation.

Xu Jing nodded, tidied up the table, and then took the snow bamboo to eat.

"What about your campus card?" On the way, Xu Jing asked her.

"Mr. Tan said that while they were still at work, he would ask someone to take me to do a temporary one in the afternoon. When the report was published in September, the school would issue it." Xue Jiao explained.

Xu Jing nodded and did not speak.

There was a long silence between them. When they got to the canteen, Xu Jing suddenly said, "I'm sorry, I'm a bit grumpy today. Before that, someone came in. It was a visitor who came in to take photos, which made Professor Zheng furious, so I.... "

She is an undergraduate, and she is still in the team, afraid that she did not do a good job.

Today I saw it was not from our school. Of course, the first thing I did was to drive out. If Professor Tan saw it, it would be her dereliction of duty!

Gu Xuejiao, no matter whether she has strength or not, is a nerd. As long as she is the favorite of teacher Tan, Xu Jing doesn't want to offend her.

Therefore, she apologized and explained earnestly.

Xuejiao shook her head: "it's OK, but I didn't understand."

She gave Xu Jing a step. In fact, at that time, Xu Jing did not give her a chance to speak.

Xu Jing himself obviously realized that the whole process of eating was very awkward and did not speak much.

In the afternoon, Xu Jing took Xuejiao to 305 again. At this time, many people came back after dinner.

When they stepped in, they were talking in a low voice.

"The bag has already been put there. It seems to be really valued by Mr. Tan...""No, I don't know if it's a nerd or not?"

"The number one scholar in our current session, what can you do in addition to endorsing and reading every day?"

"It is said that Gu Xuejiao is very beautiful?"

"Don't read a lot of rumors all day. Some people say it's ugly."

"When will they come back?"

……

"Cough." Xu Jing coughed at the door.

Suddenly, there was no sound inside.

Xu Jing frowned and went in with snow water bamboo.

Xuejiao is very simple to wear today, but it is also good-looking for people to wear it.

Her clothes are simple but elegant, and her jeans are slim and straight.

There is no need to apply powder on her face. She is already very white and her eyes are big. Now she is smiling at them, her eyebrows and eyes are crooked.

For a moment, it was very, very quiet.

Xu Jing was more serious and coughed again: "this is Gu Xuejiao, and she will be your younger sister."

Her words broke the silence, and all of a sudden, it was lively.

"Welcome..." Someone took the lead in clapping.

Snow Jiao shyly smile: "thank you, everyone, good elder martial brothers and sisters."

"Primary school sister, we have heard of you for a long time, ha ha ha ha ha!"

"Yes, primary school girl, how did you get such a high score?"

"Primary school girl is still a little beauty, ha ha!"

"Is this a little beauty? This is super beauty! It turns out that the rumors about school flowers on the Internet are true! "

"Zhao Ping, what kind of eyes are you looking at? The primary school girl is still young. Don't look at others like this!"

"Oh, Zhao Ping's face is red!"

"Ha ha ha ha..."

"Pa..." Xu Jing clapped a ruler on the table, a very serious face.

"We have started work. We must send these data to the next door today."

"Oh..." The others nodded quickly and did not dare to joke again.

Xuejiao noticed that several people turned their lips invisibly, but said nothing, and began to work.

Xu Jing didn't arrange things for her, and obviously felt that she couldn't do anything.

Other senior brothers and sisters also perform their own duties. Although some people will look at her from time to time, no one talks to her again.

Xuejiao is not in a hurry to get in and get a foot in it. She doesn't even know what to do. There's no need to worry.

All afternoon, Xuejiao followed Mr. Tan to get a card, and then he continued to stay in the office.

Xu Jing sometimes asks her to help with some things, but still doesn't give her anything.

Snow water bamboo is observed quietly.

Three hundred and fifty-five people, including Xu Jing, are drawing pictures, doing geometric and calculus calculations.

One afternoon, Xuejiao knows that these undergraduates are only responsible for a very basic part of a project. They just help with calculation and drawing.

After checking the result three times, Xu Jing sent it to 307 Graduate Office.

The door was closed all the time. Professor Tan went in twice and the door didn't open again.

When Xuejiao is free, she uses a notebook to write down, probably recording what each elder martial brother and sister are doing.

At six o'clock in the afternoon, Xu Jing let Xuejiao go back.

This is what Mr. Tan told me. If there is nothing wrong, let Xuejiao go back early and don't stay here at night.

There is no bed for her in school. A girl should not go home too late.

This afternoon, Xuejiao summed up

She is a soy sauce player

……

"Their attitude towards me is still very good, but they are very busy and have no time to say anything to me." Xuejiao said while turning over the Gao Shu borrowed from Cheng Mingze.

She had the loudspeakers on and her cell phone was on one side of her desk.

The voice of Lin Zhihua on the other end of the phone is soft

"Your elder martial sister is more serious. If you don't rush for quick success and instant benefit, it's OK. But you can't see the specific character of your elder martial sister for one day."

Xuejiao nodded: "yes, I have no bad influence on her, but I also think that she and I may not be the same way."

Lin Zhihua smiles, and the soft laughter spreads through the receiver.

"What are you laughing at?" Snow water bamboo is helpless.

"You're cute." Lin Zhihua's voice was a little smiling and a little serious. "You don't need to pay attention to anything at this stage. You just have to make no enemies with your senior sisters and brothers. You can't offend everyone. The teacher won't like a person that the whole team doesn't like."

Snow bamboo nods: "I understand."

"But unless they are like-minded, there is no need to make friends with others. Strength is the most important thing." Lin Zhihua respected his teachings.

Xuejiao continued to nod, very hard, quite agreed.

"A lot of their calculations use calculus. I'm going to have a look now. I won't be unable to help at all in the future. Alas, this is that the knowledge reserve has not caught up with the pace."She entered the team ahead of time, but had not learned the knowledge to use. In order to keep up with the team, she had to work hard in private.

"Yes, the knowledge that must be used can be learned in advance." Lin Zhihua agreed.

"So Mr. Lin, I need to hang up the phone and study now." Xuejiao chuckles and opens the lid.

Lin Zhihua slightly a meal, he some reluctant to give up her voice.

"Cough," Lin Zhihua coughed, "I'm fine tonight. Do you want me to tell you about advanced mathematics?"

"Ah Why The snow water bamboo is stunned.

The voice on the other end of the phone was soft: "my advanced mathematics and analytic geometry are all full marks. I have a quick method. Do you want to?"

Snow water bamboo eyes a bright, the head does not stop to point: "want to want to want!"

Lin Zhihua's head has always been smart, he said that quick method is definitely faster than her own reading!

However, she said, the phone was hung up, snow bamboo a Leng.

A moment later, Lin Zhihua's video phone call came.

Xuejiao smiles and picks it up.

Over there, Lin Zhihua is sitting on the chair in the study. The camera is aimed at him. He holds a pen in his hand and looks at Xuejiao and smiles

"Well, it's time for class. Please be serious."

Xuejiao immediately sat down with a serious expression: "Teacher Lin, please start."

The other end of the phone was quiet for a moment. Then, Lin Zhihua didn't hold back and took the lead in laughing.

"You."

He put his fist to his lips and coughed, "OK, it's time to start."

"All calculations, especially mathematical calculations, no matter higher mathematics or elementary mathematics, are, in the final analysis, several different formulas, combined with the operation of addition, subtraction, multiplication and division..."

Xuejiao listened carefully and wrote and drew a picture from time to time.

……

In the next few days, Xuejiao goes to the office during the day, and they are all doing things. Xuejiao reads and calculates in her own place.

When someone asked her to take something or help read data, Xuejiao went to help.

When they didn't call her, she would sit quietly in her position and read a book.

In the evening, with questions and summary, and Lin Zhihua video.

In fact, the quick method he said was to use the simplest way to make Xuejiao eat the knowledge and find out the logic. It was the same as when he taught her competition mathematics.

What Newton, Leibniz, lopida, Taylor

Or limits, calculus, series

What advanced mathematics contacts with is almost equivalent to another thing as far as mathematics has been learned before.

But the nature of things is continuous, as long as it is mathematics, there is a connection.

After several days of teaching by Lin Zhihua, Xuejiao must admit that this person's educational ability is the strongest she has ever seen.

In a few hours, he could almost finish half of the book to her.

During the day, she ate the details herself.

This day, near dinner.

Xu Jing breathed out a deep breath, hardly showing a smile.

"OK, OK, thank you all. We're finished here. Everyone is working hard."

Snow water bamboo slightly a Leng, head up.

Is that to say that the project needs their end? So these six undergraduates can go, don't you have to come?

"It's not hard, it's our honor to help." Several people laughed.

Xu Jing nodded and relaxed: "we have registered all the help we have done, and Miss Tan knows it. Wait for the project bonus to come down, the younger brother and younger sister will contact you! Hard work

"It's OK. It's OK." The others all laughed happily.

Then Xu Jing went to 307 with the data, leaving only six undergraduates and Xuejiao in the office.

Among them, two boys pushed and jostled.

"Zhao Ping, say it!" One of them pushed the other.

The one pushed stammered and stammered.

Xuejiao showed a smile, politely alienated: "elder martial brother, what can I do for you?"

Zhao Ping looked at her, blushed and said, "Gu Gu Gu, Gu Xuejiao, do you want to go to dinner together?"

Xuejiao shook her head, still very polite: "no elder martial brother, I went home for dinner in the evening."

"Oh, oh Good... " Zhao Ping's face was even redder. He answered and did not speak again.

The other several people roared with laughter. Xuejiao didn't speak and began to read.

In the past high school career, Yi Tianyu was occasionally coaxed by others.

But she didn't dare to be too far away from the students in her class at that time.

In addition, Yi Tianyu has a big temper, and no one dares to speak if he stares at him.

On that rainy day, Xuejiao knew that she was not suitable for him.

In fact, I always know that her ideas and his ideas are quite different.Xuejiao didn't contact him since she came to Beijing, and Yi Tianyu didn't contact her either.

But fortunately, she knew that Yi Tianyu reported Fudan.

Xuejiao shakes her head, takes back her thoughts and looks at the book.

Zhao Ping, they left. Not only Zhao Ping, but several other undergraduates packed up and left.

After they left, Xuejiao took a look at the time and decided to finish these comprehensive problems before leaving.

But she is a little curious. Isn't Xu Jing going to send the data? Why didn't you come back so long?

She bowed her head and stopped thinking about it. She began to solve the problem.

Lin Zhihua is right. Although college mathematics is much deeper than high school mathematics, it is all mathematics, which is based on the basic knowledge.

Xuejiao likes mathematics very much. From her last life to this life, she likes mathematics most.

It's interesting for her to solve problems.

She's just finished. Put away the books.

"Dada, dada..." There came the sound of swift footsteps.

Xuejiao looks up and sees a boy and Xu Jing coming.

"Gu Xuejiao, what about them?" Xu Jing's voice is very anxious.

Xuejiao immediately replied, "they have gone."

"How long have you been gone?"

"It's been half an hour..."

Xu Jing frowned tightly: "these guys!"

Xuejiao looked at the boy with frowning eyebrows beside his eyes, and then looked at Xu Jing: "elder martial sister, what's the matter?"

"They miscalculated a place! All the things counted today must be repeated! " Xu Jing was quite angry and stamped her foot.

She was really angry. In order to rush to the end of the day, she only asked them to check by themselves, and she only checked them once. She didn't notice that there was a problem.

As soon as they got there, they were found by the man next to them.

But fortunately, he found out, otherwise these data are directly used in the next step, she really made a big mistake!

"Ah?" Snow water bamboo is also stunned.

"Call me back!" Xu Jing stamped his feet.

The boy next to him waved his hand and said steadily, "forget it, elder martial sister. Let's do it ourselves."

Elder martial sister?

Xuejiao looks up and looks at the boy.

She knows who this person is. This is another undergraduate student of Mr. Tan's team in addition to her senior sister. She is only a freshman and a sophomore in September.

Now he's following the graduate student. His name is Zheng Jiakun.

"But are we through with it?"

Zheng Jiakun nodded: "today is OK, but it will be a little late."

He said, sitting down at the big table.

Xu Jing sighed and sat down opposite him.

Xuejiao put down her schoolbag and showed a smile

"Elder martial sister, I'll do the same."

"You?" Xu Jing frowned.

For a moment, she said, "you can't do it. It's a lot of calculation. It's all college mathematics. There's a lot of differential. You go back first, don't disturb us. "

"I've basically finished studying advanced mathematics. Elder martial sister, I'll try it."

"You really can't, our calculation is very important, you don't disturb..."

Zheng Jiakun interrupted Xu Jing: "are you Gu Xuejiao?"

"Yes." Snow water bamboo nods and smiles.

Zheng Jiakun also nodded and pointed to the other side of the table.

"Sit down and count."

Xu Jing frowns tightly, a face of disapproval.

Snow water bamboo nods, go up quickly.

Is it all university knowledge?

She can't?

If it's OK, you always have to try.
