When the bell rang, an old white haired professor with thick glasses came in.
The old professor put down his book and said, "today is the first day. I won't call the roll. I'll inform the students who haven't arrived. If you're caught skipping classes three times this semester, you'll lose the course. "
"Teacher, no one in our class is absent today. And there are more people! " In order to vent his dissatisfaction, Zhou Guangwen stood up again, glanced at Shen Lang and said, "Liu Qingyi brought a boy over. This is a classroom. Should we let the extra people leave?"
"Oh?" The old professor took a look at the waves.
Liu Qingyi got up and said, "teacher, he's my friend. He's here to listen in. The school doesn't forbid outsiders to listen, should it be allowed? "
"Teacher, it's too unruly." Zhou Guangwen frowned.
The old professor said in a deep voice: "it's unnecessary to care about this kind of rule. Of course you can listen in. There is no end to learning. This attitude of being willing to learn is very good. Well, don't waste time on this. Please take out your textbooks. Today we are going to talk about a more difficult formula. "
The old professor began to give lectures. Zhou Guangwen was in a bad mood.
Shen Lang was idle and bored, and he also heard it.
It was Liu Qingyi who was impatient after listening for a while. He covered his face with his textbook and talked to Shen Lang in a low voice. His playful appearance seemed a little cute.
After contacting Liu Qingyi for a period of time, Shen Lang also found that she was cold outside and hot inside.
"That's the formula. Do you understand it? OK, let's do a problem to consolidate it The old professor took the book and wrote down two questions on the blackboard. He said to the students, "these two questions are a little difficult. It's nothing if you can't solve them. After all, the formula is too complex. However, students who want to take the postgraduate entrance examination should pay attention to it. "
The students in the class looked at the questions on the blackboard and showed confused expressions.
These two problems are too difficult, few people in the class can solve them.
Only a few Zhou Guangwen level figures racked their brains to be the first to solve this problem.
For some Xueba, this is equivalent to a competition.
Shen Lang took a look at the topic with great interest and kept it in mind.
After ten minutes, Zhou Guangwen was the first to stand up and say, "teacher, I've worked it out. Is the answer to the first question 1?"
"Oh, you worked out one!" The old professor laughed and praised: "you are right. The answer to the first question is really equal to 1. It seems that you should have made this formula clear. If you take the postgraduate entrance examination in the future, this formula should not defeat you. "
Many students have cast an amazing look at Zhou Guangwen, who can solve this problem, is worthy of learning hegemony.
"In fact, this topic is not difficult, just need to calculate it carefully." Zhou Guangwen said with a face.
After that, he glanced back at Shen Lang and said, "I think all the students who have just listened carefully can work out this problem, and so can the student who has been listening in."
All the students looked at Shen Lang, and the old professor also looked at him, but the old professor didn't have much hope for Shen Lang. This kind of problem is very difficult, you expect a person who comes to the audience on the first day to solve this kind of problem, that is just like a fool's dream.
Zhou Guangwen wanted to find Shen Lang's trouble on purpose. He said directly, "what do you think of this problem, this fellow listener?"
There was a roar of laughter from the whole class.
Shen Lang didn't speak. Liu Qingyi frowned and stood up and said, "Zhou Guangwen, what do you mean?"
When Zhou Guangwen sees Liu Qingyi staring at him coldly, he is in a bad mood. Anyway, he feels that there is no possibility for him and Liu Qingyi, and he even breaks the jar.
"It doesn't mean much. I just want to see if your friend has any effect." Zhou Guangwen said bitterly.
The old professor waved his hand and said, "well, let's not discuss this. Let's take a look at the second question, the second question. Has anyone worked out the answer? "
Shen Lang said coldly: "the answer to this question is 2.13."
As soon as the words came out, the class was quiet for a while, and then a group of students laughed.
"I said this classmate, how did you calculate such a precise number?"
"That is, those who have gone to university should know the law of advanced mathematics, right? The answers to the most difficult questions are very simple. How can they be so complicated? "
"Yes, it has a decimal point. You are too good at it."
The crowd laughed, but no one noticed that the old professor's face on the platform suddenly solidified.
Liu Qingyi doesn't know why Shen Lang suddenly opens her mouth, but she vaguely feels that Shen Lang is not talking nonsense.
However, it is impossible to get a true answer to such a difficult question.
"Teacher, I think the answer to this question should be 2." Zhou Guangwen opened his mouth and said that he had been working hard on this problem just now, and he already had a general result in his mind.The old professor just recovered, scratched his head and said: "if the answer is 2, this question can get half the score."
Zhou Guangwen is full of satisfaction. This kind of problem is difficult to solve in less than ten minutes. He only takes about five minutes to get half of the score, and he feels very good about himself.
Zhou Guangwen thinks that in terms of knowledge, he is already very NB. If others don't know that he has such a great talent, it's a very painful thing!
So he likes to show himself.
"Well, it's just half the score." Guan Jing snorted. She can't stand Zhou Guangwen's face.
The old professor took a deep look at Shen Lang and said, "in fact, the real answer to this question should be 2.2. When taking an examination of one's deceased father grind, this kind of problem is taken as add cent item commonly. It turns out to be 2, and you can get half the score. If the answer is 2.2, you can get the full score. "
At this point, the old professor's voice pause, continued: "but, the perfect answer is 2.13, if you can get 2.23, you can get the full plus points, generally 15 points."
In addition to Qiao Xing, who is sleeping on the table, all the students in the class are shocked.
is as like as two peas, 2.23.
All the students looked at the waves again, and the previous sarcasm disappeared, replaced by surprise and shock. Liu Qingyi's boyfriend is too good to be so accurate www.novelhold.com , the fastest update of the webnovel!
