Saying that, Gu Yunnian paused and snorted, "If you want me to know that you have run one lap less, I will let you run until you wear through the soles of your shoes." ”

"Sister Yun, don't worry, I will definitely complete the task!" Sun Yuan was excited, and immediately assured, Gu Yunnian did what he said.

Gu Yunnian returned to the medicine hall, said hello to Ye Ze, and started typing on his computer.

The review syllabus for Sun Yuan has already been prepared, and now they are preparing the practice questions that Wang Xiaomeng and they have to do.

After copying all the practice documents for the next few days to the USB flash drive, Gu Yunnian was also thinking about whether she should buy a computer as soon as possible when she checked her email address for emails.

In the future, she often has to prepare study materials for her classmates, and it is inconvenient to always borrow Ye Ze's computer.

After dinner, Yun Shui Yu came to Gu Yunnian's house.

"Niannian, it's been more than a month since Jiangjingcheng was installed, when do you want to move over?"

Gu Yunnian was stunned for a moment, she hadn't looked at the self-installed house since it was accepted, and she forgot about it for a while.

She put down the book and thought about it.

It was a hot day, and the smell that should have been removed from the new house for more than a month was dispersed, and the materials used were more environmentally friendly.

In addition, they are not at home during the day, and it is not hot at night, so they don't need to turn on the air conditioner anymore, they can leave the windows open for ventilation, and it doesn't matter if they move there now.

"When does Mom think it's the right time?" Gu Yunnian asked, there is nothing to move, she can do it at any time.

"How about the 27th of this month? It happened to be Sunday, and I gave advance notice that the business would close early that day, and I would invite the medicine elders to have a meal with them at home. ”

Yun Shui asked tentatively, Gu Yunnian responded without any abnormality, and she couldn't help but show a trace of guilt.

Nian Nian really forgot.

Yun Shui Yu quickly restrained his emotions, and told Yao Lao and them about this plan at breakfast tomorrow.

At the end of the morning self-study, Principal Liu brought more than a dozen teachers into the classroom with their own benches.

Gu Yunnian also got up and walked slowly onto the stage with empty hands.

When she stood on the podium, the class bell rang.

Dozens of pairs of eyes of teachers and classmates stared, and Gu Yunnian didn't feel the slightest nervousness.

He smiled slightly, and his crisp voice was like a stream of water, "Ladies and gentlemen, today we will talk about mathematics first. In fact, mathematics is a very interesting subject, and it is also the foundation of science. Of course, it's up to you to find it interesting. ”

Gu Yunnian summarized first, and then began to explain systematically.

It was still according to the way Mu Sichen explained it to her at the beginning, but she spoke in more detail, added some examples, and occasionally related it to interesting physical and chemical phenomena.

Although physics has already been studied, for the students in Class 7, it is almost the same as not having learned.

The teacher brought by Principal Liu at the back of the classroom, from the disdain and carelessness at the beginning, listened more and more seriously as Gu Yunnian spoke.

Most of the teachers are conscientious and responsible good teachers, and they want to give all their knowledge to their students. But it is inevitable that he is a little arrogant and old-fashioned, and he thinks that Principal Liu is messing around.

It's just that Class 7 is a student who has been abandoned, Principal Liu agrees, Duan Xuewen supports it, they are not good at objecting, but they are also not optimistic about Gu Yunnian.

But at this moment, their minds changed.

Gu Yunnian's explanation was vivid and interesting, and easy to understand. The classmates listened to the laughter from time to time, but they were attentive, and none of them deserted.
