Lin Wang affirmed Liu Yi's statement and emphasized again: "Teacher, I have a very good memory, I can tell everything you say."
Lin Wang was telling the truth, but the chemistry teacher couldn't listen at all.
The teacher thought from the bottom of his heart that Lin Wang was deliberately putting rotten, deliberately looking for fault, not receiving his own kindness, and clearly doing right.
The chemistry teacher felt disrespectful and said with a black face and displeasure: "Since you know it, come on stage and show me how to use a pipette gun."
Lin Wang: "Yes!"
He walked to the podium, picked up the pipette gun, and the familiar feel came to life, as if he was doing experiments in the laboratory every day, and it was very convenient to operate.
He skillfully calibrates, adjusts the volume of liquid to be pipetted, and then immerses the pipette gun in a beaker to remove a certain amount of water.
The chemistry teacher was stunned, he really didn't expect that Lin Wang would really use a pipette gun.
The pipette gun is already a precision instrument, and it can't be touched in high school, how did this person learn it?
"You pipette another 10ml of liquid.
Lin Wang: "Yes!" As
the name suggests, the pipette is a hollow glass tube, the upper and lower ends are connected, and the lower end is pointed mouth. The upper end is plain tubular with an oval expansion in the middle.
Its use is used by ear-absorbing balls, the principle is similar to drinking milk tea, using the difference in atmospheric pressure to absorb liquid.
Lin Wang found a 10ml pipette, first plunged the lower end of the pipette into the beaker's water, and then put his finger against one end of the pipette to successfully remove a little liquid and rinse.
Next, drain the liquid from the pipette into an empty beaker and begin pipetting the body fluid with the ear suction ball.
Many new students were stunned, because Lin Wang's process of transferring the liquid was very skillful, and some of the movements were different from what the teacher explained.
Wang Dahu and Liu Yi were very worried under the podium, Lin Wang's operation just now was different from what the teacher said, and they were afraid that Lin Wang would be scolded.
The chemistry teacher looked stupid directly, he never expected that Lin Wang could use the pipette so skillfully.
If it weren't for soaking in the laboratory often, he would definitely not be so skilled!
And just now Lin Wang's action of washing the pipette, only skilled experimenters will do this, novices can't think of it at all, and they won't operate.
The chemistry teacher was amazed in his heart: This freshman absolutely often does experiments!
"This student, what's your name?"
Lin Wang: "My name is Lin Wang."
When Wang Dahu heard this conversation, he sighed heavily.
After Lin Wang, the chemistry teacher now asked him his name and wanted to deduct him the usual points.
Military schools, like ordinary universities, have the same comprehensive score in terms of cultural courses, which consists of the scores scored for performance in peacetime and the score of the examination paper.
The chemistry teacher continued, "Have you been in the lab before?"
He then added: "I had prepared for chemistry competitions in high school, so I knew how to operate these instruments.
In the face of questioning, he coped with reasons indiscriminately.
The chemistry teacher nodded with satisfaction, "No wonder, the way you washed just now is only used by the experimenter, and the novice will not use it at all."
"It turns out that you really can, I just thought you were deliberately contradicting me."
After he finished speaking, he faced all the students and said loudly: "Lin Wang's operation just now is very standard, go to the experiment tomorrow, if you can't operate, you can ask the experimenter, or ask Lin Wang directly." After
a sudden episode, the chemistry teacher changed his teaching style.
While he was explaining, he asked Lin Wang to demonstrate on the podium, and he held the instrument to demonstrate in the middle of the classroom.
So that all students can clearly see the whole process of using the instrument, so that the course progress is very fast, and the result is doubled.
The freshmen sighed offstage.
"Lin Wang's various training projects are not good, and the result is that the cultural class is also a dark horse, and everything will be done.
"It's really more popular than popular."
"I suspect that there is nothing in this world that Lin Wang will not do!"
"After
an afternoon of study, the freshmen returned to the dormitory after dinner, chatting and washing.
Lin Wang was washing his face in the water room, and Liu Wei came to wash at this time.
Liu Wei saw Lin Wang, so he walked over and took the faucet next to him to wash up.
While washing, he asked: "Lin Wang, why did you refuse the invitation of the seed club, don't you know what kind of organization it is?"
"Don't ask me first, I want to ask you, why did you refuse the invitation to the seed club?" Liu
Wei has always been a gentle and elegant image, never cold face, showing a little unhappy.
When he heard Lin Wang's question, his face was a little wrong for the first time, and then he smiled bitterly and said, "Because I don't want to go."
Lin Wang continued to ask, "If you really don't want to go, you won't hesitate when you answered just now."
After he asked this sentence, Liu Wei was silent.
Lin Wang quickly eased the embarrassment and said, "I'm sorry, I don't know this can't be asked."
Liu Wei smiled bitterly and shook his head, "It's okay, it's not a big deal."
"It's my family who won't let me go, the seeded club will have some special tasks, and training methods, my family thinks it's too dangerous."
"They want me to study well in a military school, take a scientific research or a career path, and they don't want me to fight and kill."
Lin Wang understood the meaning of Liu Wei's words.
Liu Wei's family background is very good, and his family has arranged his future path, and he doesn't want him to do dangerous things.
As long as he safely studies college and enters the army, his career prospects will definitely be beyond the reach of ordinary people.
Although it is said that the troops are a place where strength is seen, where there are people, there will be rivers and lakes, and there will be people who will love the world.
Therefore, the army will also have some related households, but there will be much less than in society, and those related households cannot do whatever they want as in society, and they will be greatly restrained.
Lin Wang responded: "It turned out to be like this, I really envy a good family like you."
Why don't you want to join the seed club?"
"
Liu Wei: ...
He used this sentence to prevaricate others, but he did not expect that one day, someone would prevaricate himself with the same words.
He never imagined that after more than a month, he would ignore his family's opposition and participate in the assessment of the seed club with Lin Wang.
After Lin Wang returned to the dormitory, Wang Dahu was pestering Qin Hao to ask something.
"Good squad leader, just tell us, why?"
Qin Hao pushed him away tirelessly, "Stay away from me and I'll just say, it's really disgusting for you to be coquettish." "
