"It's a bit of a talk, let's go back to the competition."

After Bi Wanqing finished speaking, he walked back to the blackboard and picked up the chalk.

【Mentality】

"The physics competition is just a game, that is, to compete with students from other schools and provinces, no one is afraid of anyone, but don't hold the mentality that I have to win a gold medal to escort Jingda Jinghua, after all, no matter how powerful the student is, he will definitely get the first place."

Speaking of this, Bi Wanqing paused and corrected: "It should be said that most of the students, well, the vast majority. ”

This sentence...... There's a story.

It seems that there is really the kind of academic god who knows that he has won the championship before he has even participated in the competition. Wu Bin thought secretly.

"You started too late, the question sea tactics will definitely be useless to you, otherwise I have a lot of obscure books here that can help you expand your knowledge, and it is very likely to bet on the question."

"It's not too late, teacher! Just show me, I'll be able to read quickly. Wu Bin immediately raised his hand and said excitedly.

"Hehe, okay, if you want to see it, I'll bring it to you tomorrow, but the premise is that you read the books that Teacher Cai gave you first, those are the big ones."

"Okay, I got it."

【Solution】

Bi Wanqing said and wrote four more big words on the blackboard.

"Most of the papers only need to be done once, and you will know the general solution of each problem, for example, if you want to solve the problem with an equivalent power supply, don't use Kirchhoff's law to calculate it."

After speaking, Wan Qing suddenly drew a picture on the blackboard, clapped his hands, and looked at Wu Bin: "This is a question of space forces in Jiang Sixi's special compilation.

"But in fact, there are many details in the title, such as the charge surface density is counted as two surface ......"

Listening to Bi Wanqing's lecture on himself, Wu Bin felt that it sounded quite easy to accept, and some of the steps to solve the problem and the details of thinking were explained in detail, just like what the teacher himself said just now, he could always scratch the itch.

It's very comfortable! ’

Then Bi Wanqing told Wu Bin a lot of his competition experience.

For example, "There are always unclear expressions in many volumes, because the language of physicists is taught by physics teachers." ”

"In addition to the text, the model of some questions is also unclear, and even if you figure it out, the teacher may not be able to figure it out."

"Well, just like the concept of reading comprehension, sometimes the original author's answer is useless.

"Typical examples are all kinds of soft, elastic, inelastic, non-extensible ropes, or capacitor leakage, or electric field energy density in capacitors, and so on."

After filling the entire blackboard, Bi Wanqing looked at Wu Bin's still shining eyes and smiled.

"Teacher Cai really didn't say anything wrong about you."

"Huh? What did you say? ”

"Saying that new knowledge is the same as a new toy for you, in fact, the few questions I just told you should be something you haven't been exposed to, and the average student will feel bored and bored when he hears his own bad questions, but you are different, you listen very carefully from beginning to end."

"Because I still know the basic concepts of these questions, and what you talk about, teacher, is very exciting, very good, anyway, it is the operation of the explanation thief 6, a handsome batch."

"Hahahaha, I don't understand the strange words of you children, anyway, you should be praising me, right?" Bi Wanqing laughed.

"That's a must, not to mention praise, I admire you so much, your level of speech is absolutely world-class." Wu Bin gave a thumbs up and praised again.

"Okay, okay, if you like to listen to it, ouch, it seems to be a little late, you haven't eaten yet."

"It's okay, Teacher Bi, I'm not hungry, you go on...... Oh, teacher, you didn't eat either, did you? Why don't you go to dinner first? ”

Although Wu Bin still wants to continue listening, he can't let the teacher go hungry to give him a lecture.

Looking at Wu Bin's reluctant eyes, Bi Wanqing walked down and patted him on the shoulder and said with a smile: "Why don't you go to the teacher's cafeteria with me to eat." ”

"Good, good." Wu Bin hurriedly nodded in agreement.

"Let's go, then."

The teacher and student soon came to the teacher's cafeteria, where the students could not come by themselves, but the teacher could take it.

"What do you want to eat?" Bi Wanqing took out his meal card and asked Wu Bin.

"Oh, no, Mr. Bi, I'll buy it myself."

"Don't be polite to the teacher, just be ...... Well, just praise the teacher's reward. ”

"This ......"

"Ouch, which student is so powerful, praise you, you have to invite him to dinner." At this time, a male teacher in front of the two of them turned around and said in a joking tone.

Wu Bin glanced at the teacher, but he didn't recognize which class it was.

"It's Teacher Xiao Song, I just ate it." Bi Wanqing greeted the teacher with a smile, and then introduced Wu Bin and said: "This kid has just entered the competition group, which is very interesting, I have been teaching for so long, and he is really the only student who praises me." ”

"Haha, yes." Teacher Song smiled after hearing this, and glanced at Wu Bin, "Hey? I don't think I've seen this kid in the competition group before. ”

"Well, it's the first time I've participated in the junior year of high school."

"It's the first time in the third year of high school? Oh~~ I know, this kid is the little dark horse in Cai Guoping's class, and he suddenly got a full score in the exam, and he has been promoting it vigorously in the past two days. Teacher Song thought of it immediately.

"Yes, that's it."

"There is a future, keep working hard, Mr. Bi, you talk, I'll go there for dinner first." Teacher Song said with the freshly finished meal.

"Okay." Bi Wanqing nodded at him, then turned to look at Wu Bin and asked, "Do you want to eat anything?" ”

"That's it...... Let's just scrambled eggs with tomatoes and braised eggplant. ”

It was the first time for Wu Bin to come to the teacher's cafeteria to eat, and he found that the dishes here seemed to be a little better than those in the student cafeteria, but the teacher invited guests, and he was embarrassed to order expensive ones.

"Where is it enough to eat vegetarian food, when you grow your body." After Bi Wanqing finished speaking, he swiped the hairpin and said to the canteen aunt: "Make a braised lion's head, and then a braised pork." ”

"Okay~ The teacher is right, what about the long body, what can I do if I eat less, Auntie will give you more."

The cafeteria aunt is probably also rare to see students come here to eat, and the amount given is particularly sufficient, and a large plate full of braised pork is about to overflow.

"Thank you, Auntie." Wu Bin took the plate and said.

"No thanks, no thanks, come on."

Then after Bi Wanqing also cooked the meal, he led Wu Bin to sit at a table where no one was around.

The teacher and student chatted while eating, and they were very happy.
