The sweet smell of citrus

The third party is a living person, and it is impossible not to ask a few more questions when encountering such a thing.

Asking a few words like this can easily create a feeling... So, so-and-so thinks that our relationship is very good.

It is easy to shorten the sense of distance.

So, she should gain another good friend soon, right?

A beautiful day ended in the boundless sunset and the mysterious and endless biological operations.

next morning.

Song Yi arrived at school, today Cheng Jialan also came very early, and didn't step on the spot, almost Song Yi put down his schoolbag on the front foot, and she came on the back foot.

Cheng Jialan didn't know why he came so early today, anyway... the alarm clock came as soon as it rang.

Before it was time to organize morning self-study, Song Yi was working on the test paper under the glass window. Cheng Jialan took a closer look and found that Song Yi was doing the biology test paper.

but……

What are these things?

After thinking about these strange questions, she didn't know whether it was a biology question or a math question. She paused for a moment and wanted to ask Song Yi, but she saw Song Yi with his head down, looking serious about his homework. .

She was a little embarrassed for a moment, and after hesitating, she took out the biology notebook in her schoolbag.

This note... I don't know if I don't look it up, but I found out that it still has a table of contents.

Extract the keywords from the topic, and flip through the directory according to the keywords. Cheng Jialan was very confused at first, but after seeing similar words, her eyes lit up and she turned over.

Young people, I don’t know, even if I found the content, but in high school biology, in order to get the answer to the question, in addition to knowing the concept, you must also know how to calculate.

Therefore, even though he found the similar sentence in his notes, Cheng Jialan looked at the test papers and notebooks, coming and going, but still had no clue.

Therefore, learning is indeed such a difficult thing. I feel a little interested at first glance, but I feel a little sleepy when I take a closer look.

hiss.

The drowsy person who didn't go down in the morning is about to come up, and he resisted to read it again but didn't know the answer, and was slightly agitated.

Cheng Jialan decided to put away the test paper in five seconds, and at this moment, Song Yi's voice came.

"What subject are you working on?"

"……what?"

"Why are you in a daze?" Song Yi turned his head and asked Cheng Jialan with a smile, "Don't you know how to solve a problem? Which one?"

"How do you know that I won't do it if I have a problem?" Cheng Jialan was a little annoyed, "Have you been looking at me?"

You must have seen it, but you can’t say it if you say it. Song Yi sat upright, looked at Cheng Jialan from a high place, and said: "Since you sat down just now, I haven’t heard the sound of the pen, so I’m curious to see it. for a while."

"..."

The word shame was written all over his face.

"Are you not good at this question?" Song Yi asked, pointing to the second question on the test paper.

Cheng Jialan hummed.

The second question is a fairly basic one. Song Yi glanced at the question, thought for a while, grabbed the notebook on the table, flipped it for a while, and then spread it out on the table.

"When you do the topic, you have to look clearly. Although the concept of this knowledge point is in the front, the method of calculating probability is in the back. You need to read it a little longer."

"The father's and mother's...probability...see the question clearly, and then start to calculate."

"Each question has its own way of solving the problem." Song Yi quickly released the key points and formulas, "Just do this, do you understand?"

"Understood a little."

That is, I still don't understand.

Song Yi, who is serious about his studies, glanced at the classroom clock and knocked on the table, "I'll say it again, listen carefully."

This time, Song Yi didn't just talk about this topic, but expanded her knowledge. This time, she explained it very carefully. After listening to it, Cheng Jialan nodded, "I understand this. .”

"Understood? If you understand, then you can do this topic yourself."

Cheng Jialan took his test paper, stared at the question, thought for a moment, erased Song Yilie's formula next to him, and then raised his pen.

Cheng Jialan's speed of sliding the pen tip on the paper is not fast, but generally speaking, it is quite smooth.

Song Yi stared at her for a while, and soon, a faint smile appeared in her eyes, "It's great, it's done right."

"Did I do it right?!" Cheng Jialan also heaved a sigh of relief.

"The answer is correct." Song Yi patted Cheng Jialan's shoulder encouragingly, "Be more patient when doing the questions next time."

"Oh……"

"Actually, you may be able to do these questions." Song Yi clicked the test paper, "Each of the above questions may seem difficult, but they have their own rules. As long as you master these rules, you can learn them."

"Can I master them?" Cheng Jialan showed doubts.

Song Yi hummed, "Of course, as long as you study hard, even if you can't master everything, you can get a lot."

When it comes to learning, she seems to have endless experience and experience.

only--

"You seem to have always cared about my study." Cheng Jialan looked up, "Squad leader, why do you care so much about my study?"

Song Yi was also a little confused when he heard that, huh?What is the problem?
