Finally, when it was time to collect the volume, Zhang Qiu handed in the volume, how did he say the expression on his face...... Well, it reminds Wu Bin of a rare word that Zhou Wenxiang taught them two days ago.

Falling

To describe people who are frustrated, the vernacular probably means that there is no love.

Wu Bin walked out with Zhang Qiu after handing in the papers, and he didn't know what to say on the way, anyway, now it is definitely not the atmosphere where you can ask "How was the test".

When he was about to walk out of school, Zhang Qiu suddenly said to Wu Bin: "Don't be sad, this paper is indeed a bit difficult, and it is normal that you can't do it, thank you for waiting for me to finish the exam." ”

Zhang Qiu naturally saw Wu Bin's situation, and found that he put down the pen early, obviously giving up.

“？？？”

Wu Bin scratched his head, and swallowed back the sentence "I think it's pretty simple overall."

When the two returned to the agreed meeting point, Wu Bin found that the faces of the other people were not very good.

At this time, Bi Wanqing came over and clapped his hands and said, "Okay, don't think about it after the exam, let's go, go back to school." ”

When the bus drove to the school, there was a gloomy cloud in the car, until a boy in the second year of high school said weakly: "What is the optical question in the multiple-choice question......

Quiet......

The sophomore boy originally thought that everyone in the third year of high school should be good at optics questions, but judging from this reaction, it is estimated that they are all forced to stop......

Of course, there is nothing but Wu Bin, but he thinks it is better for him not to speak at this time.

"B and C should be chosen, there is no loss of energy, so the light intensity of the light pulse after passing through the glass rod should be the same as the original light intensity, and BC is in line with this."

"Whew...... I also chose BC with this idea, and I read the question for a long time. Another junior in high school breathed a sigh of relief and felt that he had passed.

"But in the title, there are three different wavelengths of light, and they travel at different speeds in the same medium, so the time it takes to reach the right end of the glass rod is different."

At this time, Wu Bin couldn't hold back and spoke, and the eyes of several people in the third year of high school turned to him, and they began to recall the question frantically.

"Gan...... Pit! ”

The first boy who said that he chose BC had a drastic change in his face.

"Then only D is compliant!"

"Lose it! Without taking into account the reflection loss, it turns out that this is what it means, toxic! ”

A few people in the third year of high school were whimpering, and the four people in the first and second years of high school looked at Wu Bin with admiration, it seemed that only this one in the car had answered correctly.

After Zhang Qiu wailed, he asked again: "Wu Bin, have you done a few optical questions?" ”

"Russia...... I guess it's done. Wu Bin nodded.

"How do you do the fill-in-the-blank lens?"

"F is parallel to the lens, so you can make a secondary optical axis, and then extend the light rays of the dots and cross the secondary optical axis to P, so all the optical convergences ......"

"Okay, don't say it, I want to be quiet."

Hearing Wu Bin say that he was paying Guangzhou, Zhang Qiu knew that his solution was wrong, and looked out the window with a demented expression.

Now several other high school juniors have understood, it turns out that this classmate who suddenly caught the last train of the competition is a special boss!

"That, hello, you're that Wu Bin in Class 3, right?"

One of the boys wearing glasses sat down next to Wu Bin and greeted him.

"Yes." Wu Bin nodded.

"Niu Pi Niu Pi, our teacher used you as an example to criticize us miserably."

Faced with this kind of question, what could Wu Bin say, he could only give him an embarrassed but polite smile.

After saying hello, the man with glasses went straight to the point, "Big guy, how much is the charge inscription in your fill-in-the-blank question?" Is it a 6 fallacy library? ”

"No, it's 3 Miku." Wu Bin shook his head.

"Ah???h The man with glasses was petrified instantly, after all, he already understood that it was the big guy in front of him, and the answer was different from the big guy, so it wasn't a decision?

Looking at the big mouth of the man in glasses, Wu Bin explained casually: "The title says that the condition that two charged bodies no longer exchange charges is not that the amount of charge is equal, but that the potential of the two is equal, you should ignore this, all by the first ......."

"Okay, big guy, don't talk about it, I want to be quiet."

Looking at the two Shi Lezhi looking up at the sky, the remaining high school juniors suddenly trembled, wanting to ask but not daring to ask, for fear of being stimulated!

But the two in the first year of high school didn't have any scruples, especially the girl with a ponytail in it, who had slowly moved to Wu Bin's side and began to ask questions.

Bi Wanqing, who was sitting at the front, smiled as he listened to the discussion behind him, and couldn't help but think in his heart

"It seems that this year, we will finally have a student show their faces in front of those committee members." ’

When the bus was about to return to school, the little girl in the first year of high school lowered her head, blushed, and asked in a voice as thin as a mosquito: "Senior, if you can, can you add a WeChat?" I still have a few questions I want to ask. ”

It stands to reason that those junior high school boys in this situation should definitely be coaxed, but now how can they be in that mood, when Wu Bin analyzed the answer to the girl, they also listened, and they were doubting life at this time, and they felt that they had participated in the competition training with a three-year vacation.

It's the envy of the two sophomores, the title of "senior" is actually very rarely heard in school, and generally junior girls either call them directly by their big names, or they are called Brother X, and girls can call you seniors...... One is that she wants to show respect for you, and the second is that she wants to show that she is cute in front of you.

The difference between the two is almost the same as that paragraph.

If the hero saves the beauty, if the hero is handsome, the beauty will say: "The little woman has nothing to repay, only to make a promise with her body", if she is not handsome, she will say: "The little woman has nothing to repay, only to be a cow and a horse in the next life to repay this great kindness." ”

Judging from the girl's performance, it's obviously the former......

The one in the first year of high school was even more devastated, and when he knew that the two of them would compete in the first year of high school, he even thought about what their children were called! After all, we have to fight together for three years, now...... It's over, it's over.

"It's not clear on WeChat, if you want to ask questions, come to the third class of high school to find me." At this time, Wu Bin replied very responsibly.

？？？

it? There is also this kind of operation??? The whole car was stunned.

The girl didn't expect to be rejected, so she shouted "Thank you, senior" in embarrassment and ran to her original seat.

Alas, there are not many good people like me who are responsible and helpful, and it is no wonder that the people behind me are so surprised. Wu Bin couldn't help but sigh.

Park, open the door.

A group of people got out of the car one after another, except for Wu Bin, all of them looked solemn, although the reasons were different, but they all had something to do with Wu Bin.

Bi Wanqing said some words of encouragement to his classmates as usual, and then dismissed them.

"Wu Bin, you stay for a while."

Wu Bin, who was just about to turn around, stood in place after hearing this.

"Going to lunch with the teacher?"

"Okay."

Wu Bin smiled very happily, after all, the braised pork in the teacher's cafeteria is really delicious!

After the two teachers and students came to the teacher's cafeteria, several teachers in the team who knew each other said hello, including Teacher Lu Gang, whom Wu Bin had seen before.

Lu Gang naturally saw him too, so he said, "Yes, Teacher Bi brought students to the cafeteria to eat, but this is the first time I have seen it, it seems that I did well in the exam today?" ”

"It's okay." Wu Bin nodded modestly.

"It's quite modest." After Lu Gang finished speaking, he looked at Bi Wanqing and asked, "Teacher Bi, how is he doing in the exam?" ”

"I haven't asked yet, but it should be good, maybe we can raise the grade in Kasumi this time."

"Oh yo!? That's amazing. Lu Gang looked at Wu Bin in surprise, he naturally understood what Bi Wanqing meant by this.

So during the meal, Lu Gang also sat next to Wu Bin and discussed the topic of this competition.

The three teachers and students discussed in high spirits, and each question was analyzed, so the eating time was particularly long, which led to the teachers of the physics group who came to eat in the back also joined in, including Cai Guoping.

When Wu Bin said the last question of gravity, Lu Gang almost slapped the stage after hearing it, but when he thought that this was a public place, he couldn't help it.

"This is to lead students into the pit, most students must be worried about the treatment of air resistance, and once the role of air resistance is considered in the hand analysis, the gravitational equation is difficult to list."

'This teacher has something. ’

The moment Wu Bin finished speaking, he said the difficulty of this question, and as far as the teacher is concerned, it is also very powerful.

The other teachers also nodded.

"This year seems to be the year of [relatively difficult]."

Cai Guoping sighed.

High school physics competitions have always been divided into "relatively difficult" and "relatively easy", which is completely determined by the mood and level of the questioner.

"And how did you answer?" Lu Gang patted Wu Bin and asked.

"Oh, I'm ......"

After a group of teachers and students finished analyzing the whole problem, they were the only ones left in the cafeteria.

"Good solution! I'll tell you, it's good that you didn't use calculus, otherwise it's easy to ignore the problem and estimate the density of the atmosphere, and still not get the right result. Lu Gang praised vigorously.

"Thank you, teacher."

Wu Bin knew that he was definitely right when he solved the answer, so he didn't have the feeling of a hanging stone falling.

While several other teachers were discussing, Wang Xuhong, a physics teacher in Class 5, suddenly exclaimed: "I just found out that this kid is likely to have a perfect score!" ”

"That's right!"

Everyone came back to their senses from the last question, and from the discussion situation, Wu Bin's all the ideas for solving the problem were correct, as long as the process was correct, it was a proper full score player.

"Haha, I'll just say you kid can do it!"

Cai Guoping was the first to pat Wu Bin's back and laughed.

"Now we can finally leak back our faces."

"Lao Cai can, teach this dark horse, you can blow it for a year."

"A year? I'm blowing it up! Ouch, rough and rough. ”

"Hahaha."

All the teachers burst into laughter.
