Chapter 98 (1/2)
This weekend is undoubtedly another chemical weekend.
Li Zheng really felt why learning is boundless.
With the deepening of his study, 200 + chemistry, but more and more aware of his ignorance.
Previous high school chemistry learning, is just to memorize the most superficial knowledge.
For example, C + O2 → CO2, it would be good to know that carbon dioxide can be produced by burning charcoal.
Now competitive learning is to explore why this is the case.
As the old man of the library said, human beings are becoming stronger in questioning ”why”.
In the chemical process of charcoal burning, what kind of changes have taken place in the chemical bonds, what is the final structure and why.
A small amount of carbon dioxide can analyze these things, not to mention mg2b2o4 (OH) 2 in the test paper.
After mastering more basic chemical knowledge, we can deduce one or one hundred through a series of principle analysis. Without having to memorize any reaction formula, we can describe the reaction process and give the reaction results.
This kind of refining and mastering the abstract principle is also the way to win in the face of infinite universe and infinite knowledge.
If we say that the sea of learning in Li Zheng's eyes before is the boundless sea level.
Now, it is a head into the sea, witnessed the deep sea world.
Only now can we know that there is no end to learning.
But this did not dampen Li Zheng's enthusiasm at all.
On the contrary, he was more excited.
The so-called learning is boundless. It is certainly a bullshit.
When you immerse yourself in the sea of learning, the goal is not to reach a certain shore at all.
It's about enjoying learning.
If the pure sea of learning boating is not happy enough.
Why not try diving?
The scenery of the sea is always the same.
This underwater world can be more enchanting, what wonderful things have.
In the face of these new scenery, unknown and exquisite knowledge, Li Zheng has no extra mind.
That's right.
……
Monday morning, class four, senior two.
Li Zheng is different from the past. Now he comes to school at 7:50.
After all, he doesn't need to study early any more.
More sleep, more nutritious breakfast is the key.
Near class, the students are talking about the midterm exam.
”It is said that the results have come out...”
”How flustered.”
”It's only next week that the parents' meeting will be held. What can we do so soon after the results are released...”
”The long pain is better than the short pain. I just want to announce it in one breath and have a good time.”
Different from these anxious students, Li Zheng walked into the classroom with a bright red face, opened his chair neatly, and put all kinds of idle books and brushes on the table one by one.
Zhang Xiao was very envious of his appearance.
This looks like eating a big stick bone, doing a whole body spa, and having a good sleep.
”Master, did you travel on the weekend?” Zhang Xiaoke inquired, ”or did you go to the hot spring? How can you look so good. ”
”No, I've been learning.” Li Zheng gently stroked the top of his head, ”you say that, I feel that my hair has become more and more.”
Zhang Xiaoke swallowed and spat: ”what are you Learning health preservation method? ”
”Study, keep fit It's kind of interesting. ” Li Zheng kneaded his chin and thought of the cableway, ”you see, Tai Chi and anything can keep you healthy. I'm going to make a” study of health preservation method ”to let the elders and aunts gather together to study every morning to prolong their life
”Er...” Zhang Xiaoke didn't dare to think deeply. He just lowered his head and clenched his fist. ”It's possible to announce the mid-term results at any time. Aren't you nervous?”
”Not at all.” Li Zhengchang said with a smile, ”after all, the weekend study has solved the turbid atmosphere of anxiety in my body, which not only purifies my mind, but also relaxes tendons and blood circulation...”
”Enough, master...” Zhang Xiaoke grabs his head and lies on the table.
When Li Zheng saw this, he also stopped trying.
