Lin Shen sees the deer again

"Okay." Lin Shen took out the math book from his schoolbag and asked, "Where did it end?"

Yao Lu leaned over, flipped through Lin Shen's math book, and said, "Here, let's talk about this chapter today."

While talking, his hair floated past Lin Shen. Lin Shen sniffed it with his nose and asked, "Did you wash your hair yesterday? Apple-flavored shampoo."

Yao Lu blushed, and whispered: "Take a shower..., the shampoo is a labor insurance product issued by my father's work unit."

"Oh..." Lin Shen nodded, and commented: "It smells good, very apple!"

Yao Lu: "..."

"Let's read a book." Yao Lu said, and then stopped talking.

well!Too thin-skinned!This topic is dead!Lin Shen secretly sighed inwardly.

Lin Shen kept seeing the end of the morning self-study. During the period, he asked Yao Lu about two things he didn't understand. Yao Lu explained patiently until Lin Shen understood.

At the end of the first math class, Lin Shen felt unfinished. Not only did he feel that he understood everything, but his hands were itchy, and he wanted to try a few questions right away.

He didn't take a break for 10 minutes after class. He opened the math workbook and started to do the homework assigned by Mei Yanjun today while the iron was hot.

It wasn't until the bell rang for the second period that Lin Shen crawled out from the sea of ​​math problems, and said to Yao Lu, "At the same table, look at how many problems I have done in a while!"

"The homework assigned by the head teacher is almost half done." Lin Shen pointed to the exercise book, showed it to Yao Lu, and said, "Preliminary, the effect is really different, and what you told me, I feel that this math class The class was very clear!"

At this time, the teacher of the second English class had already come in and was doing daily greetings in hometown English.

Yao Lu also followed his classmates and said in unison: "Good Arfort is angry——, kicking——!" At the same time, he looked at Lin Shen's math workbook.

His hair floated back and forth from Lin Shen's nose again, Lin Shen couldn't help thinking, the apple smell is really strong, it smells so good!

Yao Lu looked up at the English teacher, and said to Lin Shen in a low voice, "Not bad, all the questions are well done."

Hearing Yao Lu's praise, Lin Shen felt that if he had a tail, he could wag his tail. He triumphantly gave Yao Lu a thumbs up, making a "powerful" gesture.

Yao Lu smiled knowingly, the two of them didn't talk any more, and concentrated on listening to the class.

After school at noon, Lin Shen took Yao Lu and went to the cafeteria to grab food like a market, and then came back after eating like a market.

After half a minute's delay, Lin Shen took out the evil chemistry workbook from his desk, slapped it on Yao Lu's desk, and said, "Teacher Yao, hurry up and give me a lecture!"

"Huh-huh-!" Yao Lu waved his hand and said, "I'll take a rest, wait for me... for a minute."

"Shun Shun Qi, Shun Shun Qi." Lin Shen stretched out his hand to run Shun Yao Lu's back, and blamed: "Who told you to run up compared to me!"

"No...you dragged me back from the cafeteria, huh—!" Yao Lu said halfway, took a breath, and said, "I thought you asked me to run with you...I'll run... Who knows that the more you Run faster."

"You idiot!" Lin Shen didn't know whether to laugh or cry, "I saw you running vigorously beside me, and I thought you wanted to run, so can I not follow? If you walk slowly behind, I'll wait for you Yet?"

Yao Lu pouted slightly, but was speechless.

Lin Shen saw Yao Lu's expression for the first time, and thought it was very cute, so he pointed at Yao Lu and smiled, "Look at your resentful little eyes, I was wrong, okay, I invite you to drink soda in the afternoon activity class."

"No." Yao Lu waved his hand, pulled over the chemistry study booklet, and said, "I'm done, I'll give you a lecture."

"Okay!" Lin Shen moved his head towards Yao Lu.

"Well... this," Yao Lu started from the first circle.

"This molecular formula is also said to be a sulfur nitrogen compound." He traced the molecular formula structure diagram on the exercise book with a pen, and said, "The molecular formula of this structure should be S4N4, so A is wrong; this molecular formula structure is a crystal, and the crystal melting point Low is a physical feature, so B is wrong; different elements composed of the same element are allotropes, this is the definition of allotropes, and S4N4 and S2N2 are compounds, so C is also wrong; D is the only correct answer."

"D said that in the molecular formula of the substance, there are both polar bonds and non-polar bonds." Yao Lu explained in detail, "As long as you can remember the definitions of polar bonds and non-polar bonds, you can easily Make sure it's true."

Speaking of this, he opened his chemistry book, flipped through the definitions of polar bonds and non-polar bonds a few times, and showed them to Lin Shen. At the same time, he drew a pen across the bottom and said, "Here, this paragraph and this paragraph."

Lin Shen read it carefully, and suddenly understood.

"This question is all about defining concepts." Yao Lu was afraid of affecting others' lunch break, so he whispered, "As long as you memorize the concepts, you won't make mistakes."

"Yes, I see." Lin Shen nodded.

Yao Lu continued to explain the following circles to Lin Shen. When the bell rang for the first class in the afternoon, Yao Lu would explain all the circles.

He let out a long breath, and said in a low voice, "It's just finished, otherwise I have to think about it later in class."

Lin Shen was very grateful, squeezed Yao Lu's arm, and said, "Thanks for your hard work, Teacher Yao, give you a pinch."

Yao Lu was a little embarrassed, and quickly said: "It's okay, no need."

The first class in the afternoon is physics class. The physics teacher spent half the class time finishing the contents of the book, and then started to talk about the problems in the exercise book left yesterday.

Lin Shen was busy doing chemistry last night, but didn't care about physics. He took out his physics exercise book and spread it out to the chapter assigned by the teacher, without writing a single word on it.

The physics teacher talked for a while, and saw how many students were shaking sleepily at the bottom, and said dissatisfiedly: "I was alone on it for the whole class, and my mouth was dry. I asked some students to stand up and talk about it." speak."

The students below became nervous when they heard the words, and a few sleepy ones were woken up by their deskmates.

"Yao Lu!" The physics teacher yelled, "Multi-choice the fourth question, what is your answer?"

Few teachers asked Yao Lu to answer questions, and everyone knew that he was timid and shy. Today, the physics teacher didn't know what happened, and suddenly asked Yao Lu to answer.

Yao Lu was very nervous, stood up slowly, held his exercise booklet, and whispered: "I chose ABD."

"What?" asked the physics teacher, "Speak up! I didn't hear you clearly!"

"Cough——" Yao Lu cleared his throat, raised his voice and repeated: "A, B, D!"

"Well, the answer is correct." The physics teacher said, "Please explain in detail why you chose ABD."

"Hmm..." Yao Lu started looking for his physics notebook, and said while searching, "I, I wrote the process of solving the problem in another notebook, I will look for it."

"Well, hurry up." The physics teacher urged.

Yao Lu found the notebook, spread it on the table, and flipped through it several times before reaching the problem-solving part.He looked down at the notebook and said: "A, the ball and the rook, the combined external force in the horizontal direction is zero, so the momentum in the horizontal direction is conserved, and A is correct."

"Yeah." The physics teacher nodded.

Because of nervousness, Yao Lu spoke intermittently: "B, momentum is conserved in the horizontal direction, so... I formulate the formula MV-MV'=0..."

"Explain what MV and MV' are." The physics teacher interrupted Yao Lu, and said, "Also, why MV-MV'=0 is listed, I didn't make it clear here."

"Hmm..." Yao Lu looked at the book, recalled for a moment, and said, "MV is the momentum of the ball to the right, MV' is the momentum of the car to the left, according to the law of conservation of momentum..."

"Why not MV'-MV=0?" The physics teacher interrupted Yao Lu again.

"Because..." Yao Lu began to recall again, explaining: "Because... I set the direction to the right as positive."

"Well, that's right, Yao Lu, please sit down first." The physics teacher told Yao Lu to sit down impatiently because he was in a hurry, and said, "Your answer is correct, but your thinking of solving the problem is not very clear. "

The physics teacher changed the topic and began to insert a summary of physics classroom education to the students: "Physics must be learned solidly, every theorem must be clear, and it can be applied proficiently. Problem solving must be done step by step, and each step must be explained clearly. Understand, this way you will know where to start when you encounter a difficult problem with many hidden conditions.”

After sitting down, Yao Lu kept staring at his exercise book and notebook, without moving for a long time.

Lin Shen looked at Yao Lu and saw that his mouth was pursed, and the expression on his face was obviously unhappy.

He pulled Yao Lu's problem-solving notebook over and whispered, "Show me, I didn't do my physics homework last night."

Yao Lu didn't speak, but nodded slightly.

The physics teacher on the stage began to explain the specific problem-solving process: formulate the formula, explain the reason, and substitute the specific value... Lin Shen checked Yao Lu's notebook one by one, and they were almost the same!There are reasons, explanations, and formulas, none of which are bad!

He returned the notebook to Yao Lu, and said softly: "Understood, return it to you."

After the physics class was over, the students had a rest. Yao Lu sat blankly at his desk, flipping through his physics notebook silently, looking a little depressed.

Lin Shen poked Yao Lu's arm and asked, "Hey, what's the matter?"

"No, nothing." Yao Lu shook his head.

After watching Yao Lu for a while, Lin Shen began to worry, why is this kid so thoughtful!It's not easy to coax!

"Hey, Yao Lu, look at me." Lin Shen poked Yao Lu again.

Yao Lu finally took his eyes away from his physics notebook and glanced at Lin Shen.

"I just read your notebook." Lin Shen looked at Yao Lu and said, "Your problem-solving process is the same as what the teacher said. The reasons, ideas, theorems and formulas are all clearly written. I can understand it very well. .”

"You..." Lin Shen paused and said, "You're just a little nervous, so the teacher thinks you're not thinking clearly, but you know that's not the case, right?"

After a few seconds, Yao Lu nodded slightly and said "Yes".

"Is that right!" Lin Shen smiled, "Everyone's personality is born, some are extroverted, some are introverted, for example, I am very extroverted."

"As for you, you are a very introverted boy." Lin Shen continued, "This is a personal characteristic, not a personal shortcoming. Extroversion and introversion have their own advantages and disadvantages. As long as it does not affect normal social interaction, there is no problem."

"I...have no friends." Yao Lu suddenly whispered.

"Huh?" Lin Shen was stunned for a moment, then pointed at himself, and said depressedly: "I'm not your friend? You really are! I've been at the same table with you for most of the semester, and in exchange for such a sentence from you, it pissed me off to death Got it!"

"That's not what I meant." Yao Lu explained in a low voice.

"Going off topic!" Lin Shen waved his hand and said, "I want to say that lack of expressive ability is not a defect. The test is about writing and arithmetic, not debate and quarrel. Besides, expressive ability can also be cultivated, as long as If you need it in the future, why do you care about it now?"

"When you gave me the topic at noon, you expressed it very clearly." Lin Shen said with relief, "I think, in fact, your expressive ability is fine, but there are too few opportunities to speak in public, but that's not important Don't be unhappy because of this trivial matter, otherwise you will stop doing anything all day long and cry from morning to night!"

"I didn't cry!" Yao Lu defended softly, "I, I seldom cry."

"Oh, I was wrong." Lin Shen corrected himself, "If you're not crying, just give me a laugh."

"You..." Yao Lu looked at Lin Shen, and after the two stared at each other for a few seconds, Yao Lu smiled and lay down on the table.

Lin Shen breathed a sigh of relief in his heart, and said with emotion: It's not easy, I'm finally coaxed!
