Following.

"It's a nice day!"

Su Chen got up early in the morning, but in fact, Su Chen was woken up by hunger.

"Chicken thief, don't catch you for me!" Su Chen simply cleaned up and went out, just to have a full breakfast.

"Hiccup" Su Chen walked on the way to school after a full meal, because it was late today, Su Chen didn't go for a morning run, but met many students who came to school on the road.

Passing by the place of last night's "car accident", Su Chen suddenly saw a complete green bush, with a big hole in the middle.

"Where did the wild dogs come from, they have broken all the flowers and plants, and they are about to be mended again." A cleaning aunt who was sweeping the floor on the slope couldn't help but curse when she saw the big hole in the car accident.

This slope is also under the management of the school, and it is the only way to enter the school, so the appearance is very important, and there are often leaders to check, and the greening must be done well.

Su Chen, who was the culprit, heard Aunt Clean's scolding and hurriedly hid in the group of students, pretending not to know, Su Chen, who had just hid in the crowd, saw Wang Wenyun driving the little sheep over the slope casually, without even looking at the big hole.

Wang Wenyun was wearing the Doraemon helmet he wore yesterday, but the bamboo dragonfly on the top of his head was put back on, but it looked like it was glued on.

"This woman is so calm!" Su Chen had to admire Wang Wenyun's determination, and he was able to turn a blind eye, as if the big hole had nothing to do with her.

Classroom for the eighth class of the third year of high school.

"Fatty, go to the Internet café at night." Zhao Shengyi said to Gao Jun with great interest early in the morning.

Every Friday is Zhao Shengyi's happiest day, because there is no need to go to class tomorrow, and the Education Bureau clearly stipulates that it is not allowed to use spare time or holiday time to make up classes for senior high school students.

Although some schools are still secretly making up classes, Huacheng Experimental Middle School has no plans so far.

"It's all on vacation, can't I go home and play? What do you do in an internet café? Gao Jun was lying on the table to catch up on sleep, and felt that Zhao Shengyi was too anxious, why did he waste money going to the Internet café when he was on vacation.

"Tsk, did you forget? There is an event in the Internet café tonight, grab red envelopes, and there is a competition, and the Internet fee will be given for the competition, and if you don't go, how about you go or not? If I don't go, I'll go find Dadong. Zhao Shengyi said temptingly.

"That's right, how did I forget this stubble, go, I have to go, Dadong he doesn't go, just his skills, Galen can't play well, he still likes to play QQ speed." Gao Jun decisively joined the camp.

"You go to the Internet café again, don't play too late, then your dad will scold you again!" Bai Yiduo couldn't help but persuade Zhao Shengyi to go to the Internet café with the fat man again.

"I know, long-winded, at most play until half past seven in the evening, no matter how late it is, it won't work, and the fat man's mother should look for him no matter how late it is." Zhao Shengyi said.

Because Huacheng Experimental Middle School is convenient for boarding students to take the bus home, on Friday, school will be released early to 4 pm, which is also a measure of humanized management.

"Jingle Bell~"

Soon the morning class bell rang, this was Su Chen's math class, and as soon as the bell fell, Su Chen came in with the test papers.

"You can find a few classmates and send the test papers." Su Chen handed the test paper to Zhou Yining, who was sitting first.

"Hmm" After last night's incident, now Zhou Yining trusts Su Chen even more, and she won't refuse what Su Chen tells her to do.

"Wow, Jingjing, you're so good, 148 points." Su Siyu was envious when she saw Yu Linjing's 148-point paper.

On the contrary, Yu Linjing took the 148-point paper and looked unhappy, as if someone owed her 3 million.

"Wow, I actually scored 80 points, it's amazing, I broke the record." Su Siyu got his paper and was suddenly as happy as if he had scored 150 points.

"Everyone has got their own papers, I'll write the answers to the multiple-choice questions on the blackboard first, and you can read them for yourself first." After Su Chen finished speaking, he picked up the pen and wrote on the whiteboard.

1.A 2.A 3.A…… 11.A 12.A

With the speed at which Su Chen wrote the answers, the more surprised the students below became, and after the last twelve questions were written, the following was already a mess.

"Oh, I'll go, I knew I wouldn't change it, it turns out that it's really all A." Gao Jun was very sad to see the questions he changed later, he had done it right, but he doubted himself, resulting in missing the score now.

There are not a few people who are like fat people.

Only two students were not surprised at all, one was Su Siyu and the other was Yu Linjing.

"Okay, be quiet, just see for yourself, don't discuss. There are a total of two people who are right about the multiple-choice questions this time, one is Yu Linjing and the other is Su Siyu. Su Chen roughly talked about the scores of the multiple-choice questions.

Speaking of Yu Linjing, everyone is very calm, after all, it is a rare thing that Yu Linjing has the wrong choice question, and there is no surprise that all of them are right, but Su Siyu's choice questions are all right that shocked the eyes of the whole class.

"Tell us about your answers." Su Chen pointed to Su Siyu in the front row.

Su Siyu, who was still happy just now, was instantly stunned, this is all right, why do you want to tell you the answer ideas.

"I, I won't talk about it." Su Siyu slowly stood up and said.

"It's okay, let's talk about it casually, for example, the first way, we know that vectors a and b are opposite vectors to each other, so which option holds true in the following four equations, and why did you choose A instead of BCD? Su Chen guided.

"Uh, this, this A looks more like it's right." Where does Su Siyu understand, if she did, she wouldn't have fallen asleep on her stomach that day.

"Okay, I admit it, many of my questions are blind, I didn't think that I was all blinded, teacher, don't let me talk about it, I can't explain it clearly." Su Siyu simply broke the jar and fell.

"Well, you sit down, listen well, it's very simple, you look at this A option, |a|+|b|=|a-b|, the two vectors are in opposite directions, I don't need to say it in front of the equal sign, I understand it, the main thing is to look at the vector subtraction behind, and the common starting point points to the reduced vector. No, the answer comes out, and the other three options draw on the scratch paper to verify it, isn't it simple? ”

Su Chen said as he drew on the whiteboard.

"Of course, when you are taking the exam, you don't have to draw all the answers, because the time for the exam is limited, and only one answer is correct in the multiple-choice questions, and you can automatically give up the verification as long as you find the correct answer and the other options, which can save a lot of time.

When you usually do practice questions in private, you can verify all the options, and you don't need to answer the questions efficiently during the exam. Do you understand this question? Su Chen asked at Su Siyu.

"Understood, it's that simple." After Su Siyu was explained by Su Chen, she understood it very easily, and Su Chen would not scold her like Teacher Huang did before, if it was before, it is estimated that she would be scolded and cried.

Now that she is in Su Chen's class, she can actually listen to it, this is a small step for Su Siyu and a big step in her life.
