Zhang Zhongzhou said with a smile while copying: "These test papers were originally intended to be kept for the selection of top students in the future, since the two students want to take the test, I will take them out in advance, by the way, the difficulty of these papers is no worse than the test papers of the Olympiad, please be mentally prepared for the two students." ”

Chen Mo and Li Xiaofeng nodded at the same time when they heard this, and when Zhang Zhongzhou made a copy of the test paper, he waved his hand to Chen Mo and Li Xiaofeng and said, "Please ask the two students who took the test to come to the podium, in order to maintain the fairness of the test, the two students will answer the questions under the supervision of the whole class." ”

Zhang Zhongzhou moved two stools in front of the podium while speaking, Chen Mo and Li Xiaofeng had no objection to this, and the two walked onto the podium. Before Chen Mo left his seat, Xiao Yuxian and Zhu Yuanxiang cheered for him in unison and said, "Old Chen, come on!" ”

Li Xiaofeng's Central Plains faction was not to be outdone, and more than a dozen classmates clamored loudly, shouting that Li Xiaofeng must give Chen Mo, a hillbilly, a little color.

Seeing that the classmates in the class were so opposed, Zhang Zhongzhou, as a teacher, not only did not dissuade him, but smiled very happily, he was very happy to see this kind of scene, and when Chen Mo and Li Xiaofeng walked up to the podium, he immediately distributed the photocopied test papers to the two of them, and then he looked at his watch and said: "It's 8:25 in the morning, if the two of you are ready, you can start answering the questions now." ”

As soon as Zhang Zhongzhou's words fell, Chen Mo and Li Xiaofeng quickly opened the test paper and looked at it, and the students in the classroom immediately fell silent, and everyone did not dare to disturb the two of them.

Chen Mo first browsed a few test papers, as Mr. Zhang Zhongzhou said, the questions on the test papers are indeed very difficult, and some of the question types Chen Mo has seen for the first time, especially the chemistry test questions, Chen Mo feels that the difficulty is extremely high.

Although he has taught himself a lot of written knowledge, the subject of chemistry is not just to master written knowledge, and without rich practical experience, your chemistry is at most a half-baked level.

There is a question in the test paper that describes the process of a chemical practice, and the test question requires writing down all the steps of the whole practice, and describing the results of each stage, such as what is the chemical reaction of the reagent in the process of fusion, and what are the properties of the liquid after fusion. Chen Mo has never done this at all, and there is no real equipment on the spot, so how can he answer the question?

Chen Mo's eyes stayed on this test question for a long time, but Li Xiaofeng on the side had already started to answer the question, and the Central Plains students in the audience immediately showed a disdainful smile to Chen Mo when they saw this, everyone felt that Chen Mo was talking big just now, and the reason why he was able to win the first place in the assessment must have been shit luck.

Xiao Yuxian and Zhu Yuanxiang couldn't help but feel nervous when they saw Chen Mo staring at the test paper in a daze.

The two of them were originally full of confidence in Chen Mo, thinking that there was no problem for Chen Mo to take down Li Xiaofeng's thorn, but at this moment, seeing Chen Mo behaving like this, the hearts of the two of them were a little up, and they were so anxious that they were anxious: Old Chen, you hurry up and start answering questions! Why are you always looking at the test papers in a daze!

Chen Mo made a bold statement before, saying that as long as he was in this class, Li Xiaofeng could only rank second, and now the two competed on the spot, if Chen Mo lost, not only Chen Mo would become the biggest joke in the class, but even himself as a member of the Linhai faction would become a joke, and it was estimated that he would never be able to raise his head in this class in the future.

Xiao Yuxian and Zhu Yuanxiang didn't want to be a laughing stock, so they were both anxious. Chen Mo naturally had the same idea as them, the reason why he stared at this test question in a daze was not that he wanted to give up answering the question, but that he wanted to solve this chemistry question first, because he felt that this question was the most difficult for him, and although the other questions were also very difficult, they had not yet reached the level that could stump him. In other words, Chen Mo wants to be difficult first and then easy, which is completely contrary to the way that teachers teach to answer questions first and then difficult, which shows that he is not a person who plays cards according to common sense.

At this moment, Chen Mo's mind is simulating the real yàn, although he has never done this real yàn, he can still imagine it. Even if he didn't know the molecular formulas of some chemical reagents, he knew the various elements in them, and when the two reagents were fused together, which of them would interact with each other, he could try to estimate them based on the written knowledge he already had.

Chen Mo carefully simulated the real yàn process, and had a general impression of the whole step in his mind, but he could only guess the phenomena produced in the process of chemical reactions, and he could not imagine the properties presented by the real yàn results, all he could do was to deduce the chemical molecular formula of the final substance.

Chen Mo thought for a few minutes and then prepared to start writing to answer the question, this question has a total of thirty points, if he can accurately calculate the final chemical formula, he can get fifteen points, and the remaining fifteen points belong to the description of the chemical reaction in the real yàn process, he only relies on guessing this part, if he is lucky, he may be able to increase the score, if he is unlucky, he can only lose these fifteen points.

Who knew that he was just about to start writing, and Zhang Zhongzhou on the side suddenly said: "Classmate Chen Mo, this question belongs to the real yàn question, and there are no test tools here, so you can not answer, and this question will not be included in the total score when the final score is counted." ”

Zhang Zhongzhou saw Chen Mo in a daze just now, and when he was curious, he came to look at it, and found that Chen Mo was staring at a chemical question and pondering, he immediately thought of the reason, so he opened his mouth to remind. After saying this, he turned his head to Li Xiaofeng, who was answering the question, and said, "Li Xiaofeng, can you not answer the last question of the chemistry test paper, do you hear clearly?" ”

Li Xiaofeng nodded while answering the question, Chen Mo smiled bitterly when he heard this, he thought to himself: Teacher Zhang, can't you say it earlier, I've been thinking about it for a long time, and I finally came up with some eyebrows, and you just denied me with such a sentence, isn't this a pit person? Forget it, whether this question counts or not, I will write down the answers I have come up with in my mind, otherwise wouldn't all such a long time of thinking be wasted?

Chen Mo thought of this and began to write and answer the question, Zhang Zhongzhou couldn't help but be stunned for a moment when he saw that he was still answering this question, he thought that Chen Mo didn't hear clearly, so he wanted to remind him again, but after seeing the chemical formula written by Chen Mo, he immediately swallowed the words he was about to say, only to see his eyes wide open and look at what Chen Mo wrote with a shocked expression, and it took a long time before he spoke: "Chen ...... Chen Mo ...... How do you know these chemical formulas......? ”
