"Sodium metal is a metal with a silvery-white luster. Today we are going to do experiments on sodium metal, and we are not allowed to make trouble in the laboratory, let alone ......" Mr. Qiu's eyes suddenly froze, "Wu Xiaoxiao, did I say I can move?" The hands trembled, then quickly withdrawn.

"Okay, now please take out a piece of sodium metal with tweezers." The metal sodium stored in kerosene is indeed difficult to take, the bottle mouth is small and slippery, due to the matter of the pairing group, Dong Chunchun and Xia Xiaowu are in a group.

"Ya'an, give me a filter paper...... Xia Xiaowu brought the filter paper.

"Ya'an, give me the blade......" Xia Xiaowu handed over the blade.

"Ya'an, look, this one is really easy to cut, and if you look at its facet, it will soon darken as the book says. Would you like to try it? ”

"No, no, no." Xia Xiaowu was surprised, Dong Chunchun could still be so excited about such a dangerous chemical experiment, "This is the encounter with air oxidation?" Dong Chunchun nodded and continued to prepare for the next experiment; She seemed to be very excited about holding a knife.

On the contrary, Lin Feng was a little in a hurry, and in order to facilitate the grouping, Lin Feng and Susan were divided into a group again.

"Susu, you, don't put it directly on the table, it's corrosive!"

"I, I'm not looking for a filter paper, you wait, hold on a little longer......" Susan still couldn't find it, so she simply did the next experiment on the reaction of sodium and water, picked up the tweezers and threw it in whole.

"Susu, you, what are you doing!" Lin Feng's frightened little eyes, "You, you, you're too big!" ”

Immediately, the surface of the water in the beaker suddenly seemed like a wave on the sea, and as the white sphere continued to shrink, it hissed and bubbled with a frightening bubble, and the walls of the cup condensed into droplets of water due to the sudden heat.

"Come here, come here!" Lin Feng grabbed Susan, and the people on the side were stunned and hid a few meters away.

Mr. Qiu rushed over, in fact, it was okay, but the experimental phenomenon was too obvious, and there was a false alarm.

At the end of this class, Dong Chunchun and Xia Xiaowu took the turn to stay and clean up at the end.

Since the next class was going to do experiments, Mr. Qiu asked them to tidy up during the big recess, just to avoid the exercise.

A breeze was blowing, and the November day was already starting to get cold, and the boy craned his neck slightly. It was still a little cool in his autumn school uniform and collar, and another boy followed him in small steps.

"Chen Zifeng?" Teacher Qiu stopped him, "Don't you have to go for a run?" ”

The boy named Chen Zifeng pressed down his collar slightly and said, "Teacher Qiu, it was Teacher Zhou who asked us to sort out the equipment in advance." ”

The other boy ran a little panting, but he still asked anxiously, "Mr. Qiu, are we doing the sodium experiment today?" ”

Teacher Qiu nodded and pointed to the room inside, "I asked a few students from Class 4 to tidy up inside, you should go in and help them, and besides, you are not allowed to make trouble in the laboratory!" The two boys looked at each other and nodded, and ran in small steps.

……

"Ya'an, go wipe the blackboard." Dong Chunchun is mopping the floor.

"Good!" Xia Xiaowu reached the top, jumped a few times and finally reached the top, "By the way, what do you want to write silently in the next class?" ”

"Did you go back yesterday to memorize, the Mencius one?"

"Fish, I want too; Bear's paws, as well as I want. You can't have both...... "Xia Xiaowu reached the top, every time he made a hard effort, the bite was aggravated once, and the content was memorized fluently.

"Classmate, why don't you come?"

Xia Xiaowu didn't stand firmly, leaned on the blackboard and snorted, and then the face was familiar.

"Oh, you?"

"Chen Zifeng?" Dong Chunchun came up from behind with a mop, obviously the two of them knew each other, "I just said that the next one should be in your class." Why did you come here early, the drill is over? ”

The little tiger tooth named Chen Zifeng took the blackboard eraser in her hand, "We, we were purely caught by Boss Zhou as coolies." ”

The other boy also nodded, staring at the equipment on the table, "Our boss Zhou doesn't care about this kind of thing, as long as our class is on the side of learning, that's the most important thing!" ”

Chen Zifeng finished his work neatly and began to drag the ground again, "You guys should go back to the class first, so it's convenient to endorse." Teacher Qiu said, just leave this to us. The other boy nodded in agreement.

Dong Chunchun picked up the book and nodded neatly, "Then thank you, let's go back to endorse the book." Saying that, Dong Chunchun saw Xia Xiaowu's eyes, like a black chicken in the night, obviously with her eyes open, but she couldn't find what she was looking at.

……

"Brother He, they are from the fourth class next door, right?"

Another boy named He Xiaobo sat down and began to drum, "By the way, Dong Chunchun from Class 4, don't you know?" I thought the whole grade knew about her, and everyone was now posting about her online. ”

Chen Zifeng sighed slightly, "Dong Chunchun, why don't I know him, we are in a make-up class." However, there is another one, I don't seem to be impressed, and it is also in the fourth class? ”

He Xiaobo still took out a piece of sodium, "How do I know, but I really want to know about Dong Chunchun......

"He Xiaobo." The hands that stared at restlessness and sinfulness were more like a falcon.

He Xiaobo pouted slightly and smiled, "Uncle Feng, I'll just play with it, Teacher Qiu won't find out anyway." ”

Chen Zifeng smiled and popped out a few words from between his teeth, "Put it back." ”

"Oh." He Xiaobo withdrew his hand aggrieved.

……

"Ahh Probably because of the change of seasons, Xia Xiaowu sneezed again, "Why do I always feel that someone is saying bad things about me behind my back." Susan, isn't that you? ”

"I-" Susan turned around with her Chinese textbook, "I still have a left eyelid that jumps, and I don't see anything bad happening." Maybe someone is thinking about you......"

Xia Xiaowu glanced at her eyes, and then grabbed her arm, "Oh, who is it?" ”

"The sophomores." Susan looked like she could see through her thoughts, "Didn't you ask me when the study abroad program would end last time?" ”

"When?" Wait, those sophomores?

Susan looked at her with a little deep meaning, "I said, why do you want to know Luo Huaicheng's whereabouts so much?" Could it be - what kind of infatuated schoolgirl are you? Now in the novel, this kind of domineering president's infatuated young wife is popular. ”

"Where are you looking?"

"Let's post it!" Susan pulled out a small book from the bottom of the drawer, "I went to our school library and found a few too, I haven't read them yet, so I'll give them to you first." ”

"No, no need...... "School library, and this?"

"He used to live upstairs from my house, and my mom and his mom were good friends, sort of, one of my older brothers. He moved not long ago, and he hasn't been in touch since. ”

"That's ...... Childhood sweethearts, this kind of innocent novels, generally not many people read them. Lately, everyone likes to be a little heavier......" Susan closed her eyes and completed an arc with her eyebrows, "Okay, I've asked our Benjack, and this exchange program is only one semester." All exchange students need to come back to take the final exam, so your Luo Huaicheng will come back at the end of the semester. ”

"What do you call me that, wait......" Xia Xiaowu leaned closer, stared into Susan's eyes and asked, "You and Jack, what do you use to communicate?" Sign language or lip language? ”

"I used to-" Susan's inadvertent glance glanced at a figure passing by, "I, I suddenly forgot to go to the office to get my English homework." I'll talk about it when I come back......"

"Workbook?" Xia Xiaowu glanced at the class schedule, and when he turned around, he was gone, "But yesterday's homework, you, you just handed it in before the last class?" ”

……

The provincial office building is located at the back of the teaching building, and further back is the senior year. So running down from the fifth floor and getting to the office every time was a struggle. Lu Haoze walked all the way, and he always felt a chill in his back, and finally, he found out that this was not a coincidence.

"You, what are you doing after me?"

Susan stood on the upper staircase, stepping up a small step, still bending her eyebrows, "What a coincidence, Lu Haoze." I go to the office to get my homework, do you want to go too? ”

Lu Haoze didn't say a word and continued to walk forward, the chill on his back should be her.

"That, Lu Haoze, I, do you remember me?"

"You and Xia Ya'an are in the same class?"

Susan finally found something to say, "yes, yes, I'll sit at Ya'an's front table, and we'll be on good terms." Lu Haoze still shook his head and continued to move forward.

"Actually, we met last time." Susan was still vigilant on the steps behind him, "By the way, is there a follow-up to the fight with the colonel you said last time?" ”

"It's gone."

"Gone?" How does Lu Haoze feel that this girl seems to be a little disappointed, even if ordinary girls are not afraid of fighting and causing trouble, they will not be interested in this kind of thing, does she have violent tendencies? The back is even colder.

"I'm literally going to the office to get my homework. But if you don't really want to go in, you might as well go back to the classroom. ”

"Who said I wouldn't go in!" Susan took a step in, her expression smug in her expression, "I told you, I'm here to ......"

"Susan?"

There was a gust of wind behind Susan, no, a unique aura, and when she heard this voice, her whole body moved with it. Then he turned his back, "Wang, Teacher Wang...... You, hello. ”

"Okay, look at your math homework yesterday, what it looked like, come in for me!"

Susan really wanted to take back that sentence, her left eye sometimes jumped, and nothing good happened.
