After lunch, everyone came to the classroom one after another, everyone rested, read books, and the punctual time for class was two o'clock, after Labor Day, it was changed to the summer schedule, and there would be an hour's nap at noon.

As Yang Chen, who has collected the memories of his previous life, of course, he found his seat with a light car.

Yang Chen suppressed his curiosity about that system and sat quietly in the classroom, preparing for the review and afternoon lessons.

He wanted to wait until the evening to talk about it.

Although Yang Chen was not short, he sat in the middle of the classroom.

The table was stacked with books and exam papers, and the drawer was also stacked with books, as well as a few pens, ballpoint pens, and a box of Hero brand ink.

There were so many books on the table that if a slightly shorter person stood in front of the classroom, there would be no students studying hard at the door.

These books can easily make people like Yang Chen drown in stacks of books.

Yang Chen wanted to lie on the table and rest for a while, but unexpectedly, the girl in the front row turned her head, took a test paper and asked Yang Chen, "Yang Chen, how do you do this question?"

This girl's name is Tang Li, her academic performance is average, but she is hardworking, her life is relatively simple, and her relationship with Yang Chen is also good.

Yang Chen later heard a little wind in a class reunion, saying that in the third year of high school, there was a girl who had been silently liking him, which shocked him for a while, because he had always had a favorite object since the second year of high school, so he ignored the girls in the class a little. Although there are no big beauties at the level of disaster to the country and the people in the class, the few girls are simple and generous, and they all have their sincere and lovely side, Yang Chen really didn't know that he still had someone in the class who liked him.

And this girl is Tang Li, Tang Li has always sat in the front row of Yang Chen, although the head teacher Teacher Wang will arrange for students to change seats every week, but most of the time they move laterally, and they move together in two rows, so Yang Chen has always been at the same table as Chen Hao, Tang Li and He Lin have always been in the front row of Yang Chen, but sometimes, they will also switch back and forth, so that Tang Li and they have become Yang Chen's back row.

Yang Chen saw that she was referring to a chemical analysis fill-in-the-blank question. That is, according to some descriptions and their conversion relationships with each other, the chemical formulas of other substances in the blank space are deduced from known chemicals.

Yang Chen is proud of his chemistry grades, which have been among the top two in the class since the first semester of high school, and even the authority of chemistry subjects in the class.

Of course, some simple topics, Yang Chen is also handy.

Yang Chen read through the question slightly, and quickly analyzed a few chemical formulas in the blank space, and gave Tang Li a detailed explanation. Zinc and hydrochloric acid produce hydrogen, hydrogen is dried by concentrated sulfuric acid, and then hydrogen and tungsten trioxide are reduced to produce tungsten and water, and the atomic weight of tungsten can be determined according to the mass of the material before and after the test tube.

(When I was in high school, such a chemistry problem was really difficult to be despicable, but after so many years, the topic itself has almost forgotten, if there is a problem with the above examples, please help correct the —— author)

Tang Li looked at Yang Chen with a look of admiration, "Yang Chen, you are so smart, why can't I do it all the time! I see that you take chemistry class every day, and you don't listen very carefully!"

"This, it is very important to master the knowledge points, and it is necessary to know all the individual knowledge points by heart, and it will be handy to start the questions. Yang Chen smiled embarrassedly, in chemistry class, he really didn't listen very carefully, he just chatted with Chen Hao, but every moment he listened to it caught the point of the teacher's explanation. Anyway, just to cope with the exam, Yang Chen thinks that there is not much innovation and breakthrough thinking, and the test-oriented education may be a mixed credit for him.

And his chemistry grades have always been very good, and the head teacher, Mr. Wang, also turned a blind eye to his desertion and chatting in class.

Mr. Wang Bing, the homeroom teacher of Yang Chen's 2000 class 3, is the chemistry teacher of Yang Chen's class.

Because the college entrance examination is approaching, the new knowledge of each subject has been learned, and now it has already entered a full range of systematic review, in order to facilitate the natural coherence of each subject, now, basically each subject is taken together in two consecutive classes, the first half of the class exam, the second half of the class explains the test paper, sometimes, both classes are used for the exam. Because the regular college entrance examination time is two hours, two classes, plus between classes, it is almost two hours.

There is no doubt that after the class bell rang, the head teacher, Mr. Wang Bing, the teacher of chemistry class, entered the classroom with a stack of test papers.

"Yesterday's exam, the results are generally satisfactory, I hope the students work hard to maintain, this exam questions are slightly less difficult than the college entrance examination, the average score of the class is 107 points, the highest score is 139! There are 15 points on 110 points. Li Xiao, 139!" Teacher Wang explained the overall situation of this exam.

As soon as Yang Chen heard that Li Xiao had taken the 139 test, then his score this time was definitely not the first.

"I won't read out the rest of the results one by one, and I hope everyone pickets their own shortcomings. ”

Li Xiao and Yang Chen are competitors in learning, but the relationship between everyone is usually very good, although they are secretly competing, but it is necessary to improve each other.

"Yang Chen!" When Teacher Wang called Yang Chen, Yang Chen walked up to the podium and took back his test paper, a bright red 138!

"Alas," Yang Chen sighed, only one point less than Li Xiao, and the first place result was lost.

"138! Yang Chen, you are unlucky enough, only one point less than the first place! This limelight thing has no part of yours, look at Li Xiao!"

Yang Chen saw that Li Xiao was also looking at him, they would smile heartily, after getting along with classmates for so many years, everyone is more familiar with each other, sometimes, the test results are good and bad, but on the whole, they are comparable.

"Chen Hao!Chen Hao!" When Teacher Wang called Chen Hao's name, Chen Hao was still chatting with Yang Chen with his head down.

"Yes!" Chen Hao hurriedly stood up and walked up to the podium to retrieve his test papers.

"110! Yang Chen, I can't copy your results even if I copy all of you, alas! Of course, the test will not be as strict as the college entrance examination, and Yang Chen also spread out the paper for Chen Hao to copy.

"Chen Hao, it's useless to say this at this time, who told you to study not much, the college entrance examination is about to begin, and I can't let you copy it in the college entrance examination room!"

"Alas, our brother didn't expect the college entrance examination for a long time, he just wanted to experience such an atmosphere when he went to take the exam, you said that he studied in high school for three years, and in the end he didn't even enter the college entrance examination room, is that a failure!" Chen Hao said self-deprecatingly.

"There are no absolutes in the world, maybe some changes will happen in the next two months!" Yang Chen wanted to comfort Chen Hao, but he thought of his own identity, he was reborn, in order to seek some changes, but in fact, can he really change!

"Hmm!" Mr. Wang finished handing out the test papers, and the students below immediately quieted down.

"In this lesson, let's explain this paper, the first multiple-choice question, what is the gas that smells of rotten eggs...... Some students choose B, and the question clearly says that it is gas, B is iodine, and iodine is liquid at room temperature. Therefore, some questions can be directly answered by reading through the question stem, so you must pay attention to some important tips of the question stem when doing the question, and do not make unnecessary mistakes. ”

Yang Chen looked at the test papers, the multiple-choice questions were all correct, the fill-in-the-blank questions were two blanks, and the analysis questions were one wrong, and 12 points were deducted. In all subject exams, if you want to get a high score, you can't go wrong with multiple choice questions, because multiple choice questions are relatively less difficult, and there are rarely some ambiguous answers, unlike political questions.

When Mr. Wang explained the analysis question that Yang Chen was wrong, Yang Chen found that his answer was obviously the same as the answer Mr. Wang said, so how could he make a mistake!

That's a 6 point for this analysis question!

Moreover, Yang Chen felt that his analysis ideas were correct, and this question did not seem to be the most difficult in this set of test papers, and the more difficult questions in the back were all done by himself, and it was impossible to make this simple truth.

However, Yang Chen didn't need to distinguish it, but in the most ordinary exam, nothing could be explained.

Yang Chen's train of thought followed Mr. Wang's train of thought and carefully combed through the whole set of test papers, and felt that there was nothing missing. It's time for the end of class.
