Chapter 253 (2/2)
After breakfast and bus, Yang Changle took us through some formulas and repeated several points for attention in the examination.
At 8:50, Li Zheng and Lin Yujing entered their respective examination rooms.
There are still 10 minutes to go before the final theoretical examination of the national physics competition for middle school students.
What's very annoying is that Li Zheng and Huang Lingqi are arranged together, which happens to be the front and back seats.
Only this time, Huang Lingqi's attitude changed a little.
Become very awe stricken.
”Well This... ” Huang Lingqi turned back and stammered, ”I'm just curious. I don't mean anything else That is When you do it Constantly let the other side speak some humiliating language Is this a great way to play? ”
”What?”
”It is Are you the kind of person who needs some stimulation to react... ” Huang Lingqi carefully described, ”for example, before us, you also need some stimulation to respond to me Does this have something in common with your favorite way of playing? ”
”What are you going to say?”
”Forget it I'd better fight... ” Huang Lingqi raised eyebrows and said, ”the exam is about to start. In order to enter my circle of friends, come on.”
”You think too much. I've chosen my car.”
”Yes, that's how it feels.” Huang Lingqi nodded excitedly, ”that's how you talk to me.”
”Insane.””Wait, I'll try again...” Huang Lingqi didn't want to say, ”Lin Qie Jing is ugly.”
”You dare to say that again!”
”Ha ha ha.” Huang Lingqi laughed and patted Li Zheng, ”no more. I wish you good grades in the exam. If you are really higher than me, I will also pay for the driver's license.”
”I don't understand. Do you like to throw money out so much?”
”It's called investment.”
After a while, the three invigilators entered the room, and all of them kept their voices.
At 9 o'clock sharp, the paper will be distributed and the examination will begin.
Li Zheng took the paper, took a deep breath, and then completely vomited out, emptying the miscellaneous thoughts.
There are many strong players in the physics competition. At present, there are two who have higher static scores than Lin Yue.
Never despise your opponent just because you dominate Jijing.
Even Huang Lingqi, whose front desk looks very unreliable, should not be underestimated because of his bad appearance.
Now, in front of this physical altar.
Even if it is only 1% difficult.
We should also take it 100% seriously.
It's like the first competition.
Start to examine the topic!
Before Tao Feifei has stressed many times, the difficulty of physics competition preliminaries, semi finals and finals is very steep.
At present, the first instance is sure.
Six questions, 280 points in total, full of 11 pages.
In terms of the length of the problem surface, it has already crushed the rematch.
More importantly, the examination time is only three hours.
For some novelists, even if you give him three hours to make up a story, you don't have to fill in the 11 pages.
The most exaggerated is the sixth question, which is full of three A4 papers!
The score of single question has reached 80.
It is equivalent to the two big problems in the finals of previous years.
It's hard to read the super question.
This question also immediately attracted Li Zheng's interest.
Just a look, then helpless smile.
Like the Super Puzzle of the second round, this question is also like a paper, and its content is exactly the content of ”optical tweezers” in last year's Nobel Prize in physics.
Candidates must understand thoroughly in a very short period of time, and according to the requirements of the topic, make a lot of calculations to solve the problem.
It can even be said that for many players, it is not necessary to finish the problem in three hours.
And Li Zheng, very unkind smile.
In the final sprint stage, he and Lin Yujing are all engaged in the thesis from the beginning to the end.
The first year's Nobel Prize winner's paper in Physics How can you not touch it?
Of course, this big man won the prize not only for a paper, but for his pioneering achievements in the field of laser particle manipulation in the past decades, with at least ten papers related to it.
It is inevitable that some of them are very deep, involving high-precision experiments, and now Li Zheng and Lin yuejing can't chew them down.
And this exam, the test is only the most basic principles, is the old man 10 years ago to determine the basic principles of the experiment.
Therefore, for Li Zheng, this is not a field study problem at all, it is just a common application problem, the formula has been put out for you, and the amount of calculation is not too much.
It is even simpler than the other five questions.
Now that he has seen this, Li Zheng has to choose to start from the last problem of ”the most difficult”.
He doesn't want to
No way. He has learned too much.
The adjacent examination room, Lin Yue Jing also showed a similar, ungrateful smile.
I can't be blamed for that.
In the two examination rooms, the invigilator also saw the real question for the first time. After a rough scan, his eyes were fixed on the last one. He was quite surprised.
”Isn't it difficult to be a man...”
”Let high school students solve the problem of Nobel level really.”
”Forget it. After all, it is necessary to select top physics talents. Although this problem is beyond the standard, it still lists all the things needed, and you can always do it carefully.”
”That's to say, but the examination time is only 3 hours. The calculation amount of the first five questions, 3 hours, is not enough to achieve the sixth question at all.”
”Normal, 280 points of papers, not a few of each year on the 200?”
”Well, let's go around first. There are some dishonest ones.”
”Go, go, go.”
So, the teachers on both sides walked up.
To say that the comprehensive strength of the contestants, in fact, the latter session is always better than the previous one.
The reason is that the intensity of training inside and outside the school has been improved. Although there are a lot of question types and routines in the competition, they can't bear to put so many teachers and students into it for years.
It can be said that the teachers of the test group have been fighting wits and courage with the competition training teachers.Now, it is difficult to make innovation in the question type. There are two main directions to improve the difficulty.
First, it is simple and crude, and everyone is angry at ”increasing the amount of calculation”.
The effect is immediate, and the disadvantage is very clear, which is ”very physical”.
Therefore, the competition has the good name of the national calculus competition for middle school students.
Another direction is ”reading comprehension”.
Find some interesting papers, make deformation explanation, on-site learning, on-site inspection of students' comprehensive understanding ability, and even scientific research ability.
After all, there are too many papers and directions, and it is very difficult for the examination institutions to organize the training in this respect.
It is because of this, this move is repeatedly tested, the problem is bigger and bigger.
When the teachers of the two examination rooms visited, most of the students were still working on the calculation of the first question, but they could already see some differences in the speed of solving problems.
Different from the college entrance examination, the speed of problem-solving is very important in this kind of competitive examination.
It can be said that only after completing the first five questions in two hours can we challenge the sixth question and score 200 points in theory.
In an examination room, there are only a few people who can reach this speed.
For invigilator teachers, looking for such students is also a rare pleasure in the process of invigilation.
It's fun to see who can pick out the seed players.
The teachers of the two examination rooms also stopped by Huang Lingqi and Qi Yingnan for a short time.
Yes, in more than ten minutes, the first question has been solved.
When they came to Li Zheng and Lin Yue Jing, they frowned slightly.
How to start solving the first problem?
This kind of mechanics problem, there is no difficulty in thinking, is the ability to spell calculus.
It's not that Li Zheng (Lin qiojing) is very strong.
This is it?
More than ten minutes, that's it??
But as soon as they were about to leave, their bodies suddenly became stiff again.
Wait, what's that?!?!
Sixth question It's over???!
I can go to your mother!!
