Love you forever

The life in the third year of high school was boring and repetitive. I kept writing papers, writing papers, taking exams and then taking exams. Anyway, I either defeated the sea of ​​questions, or I died in the sea of ​​questions.

When I come back in the morning, I will read books consciously, and after lunch at noon, I will continue to write my classwork. In the evening, the teachers of various subjects come to take exams, and a large pile of books are piled up on the table like a castle.

"Zhou Yin, do you want to eat hawthorn?" The most idle person in the class is Su Jin who resigned. He sleeps when others read books, draws pictures when others take exams, and rests when others finally rest. Even He Ge doesn't lend him comics anymore. , and the reason is very high-sounding, how can there be time to read comics after the college entrance examination?

Su Jinci: "..."

Su Jinci, who felt that she was a different kind, went to harass Shen Changzhou and Zhou Yin from time to time every day.

Zhou Yin was explaining yesterday's math papers to Shen Changzhou. There are so many papers every day, how can the teacher explain each question one by one, and just pick a few difficult and important ones. It just so happens that Shen Changzhou has no foundation. , It's like reading a book from heaven, but luckily he has a boyfriend who is a top student.

"Zhou Yin, do you want to eat?" Su Jinci did not give up his harassment.

Before Zhou Yin could speak, Shen Changzhou said first, "Put it on the table, then shut up and get out and play."

Su Jinci: "..."

Su Jinci expressed his grievance.

Zhou Yin tilted his head and glanced at him, "Thank you."

Su Jinci: "..."

It's really not easy for polite people to refuse.

周阴又转过来，声音清晰的跟沈长舟继续讲：“1是方程x-4xm=0的解，x=1代入方程得m=3

because x*-4x

The solution of 3=0 is

x=1 or x=

3, so b=

{1,3}...

Zhou Yin wrote on the paper while talking, Zhou Yin's handwriting is beautiful, and it looks like a standard answer.

Zhou Yin finished writing the last word, then turned the paper over to Shen Changzhou, "You read it again, and I will give you another example."

"Oh." Shen Changzhou obediently began to look at himself, turning the pen in his hand a few times, until Zhou Yin's sample question had been written, and the final result was that Squad Leader Shen still made a mistake.

Shen Changzhou looked at the big red cross: "..."

Mr. Shen, who was all-powerful back then, with an annual profit of hundreds of millions, is now dead because of it.

Shen Changzhou looked at Zhou Yin's expressionless face, and said cautiously, "Then the next question?"

Zhou Yin sighed inaudibly, "Look at this question, we know that 1, x,

The three real numbers of x2 form a set, x, the conditions to satisfy are:

ax≠0;

bx≠1;

cx≠±1;

d. x≠±1 and x≠0..."

Zhou Yin patiently read the questions one by one, and then gave the answer: "Because the elements in the set are different, so x≠1,

x2≠1，x≠x2，所以x≠±1且x≠0

Choose d. "

Zhou Yin wrote down the final answer, and Shen Changzhou nodded thoughtfully.

"Long boat." Zhou Yin put down his pen and looked at him.

Shen Changzhou was taken aback, "Huh?"

"Remember to bring a protractor during the exam." Zhou Yin said it very seriously, making Shen Changzhou a little inexplicably serious: "Why do you have to?"

Zhou Yin didn't change his face and said: "When you meet an analytical geometry problem, you can measure it directly. If it's a process..." Zhou Yin paused, and then continued: "If it's a process, don't force yourself."

Shen Changzhou: "..."

Is such a boyfriend who doesn't give face really good?

Su Jinci, who was playing over there, laughed and slapped the table several times, "Zhou Yin, why are you just telling the truth."

Shen Changzhou didn't dare to say Zhou Yin, and didn't dare to scold Su Jin for resigning, "Get lost!"

Su Jinci embraced Shen Changzhou's shoulders, "Brother, I said earlier, the nine-nine multiplication table is suitable for you."

Shen Changzhou rolled his eyes: "...Get lost."

"I'm telling you the truth." Zhou Yin frowned, not joking, "During the exam, there will be some tricks to steal points. In the college entrance examination, one point difference may make a big difference. Remember There's no harm in that."

Zhou Yin spoke so seriously that Su Jinci was embarrassed to laugh, and Shen Changzhou became a good baby.

"The last problem in the conic section is often very complicated to combine, which makes k impossible to calculate. At this time, you can use the special value method to force the k process, that is, first combine, and then calculate the delta. Use the Weida theorem , listing the expressions to be solved for the problem.”

Zhou Yin found a demonstration for him while talking.

"There is a step in the proof of space geometry that I really can't think of. Just write down the conditions that have not been used, and then draw the conclusion that I can't think of.

If the first question is really not going to write directly and the conclusion is true, then the second question can be directly used

It is recommended to use the conventional method to establish a space coordinate system casually, and you can get 2 points if you make a mistake. "

Shen Changzhou nodded and listened carefully.

"The third question of the last big question in mathematics often uses the conclusion of the first question, and when you can't do multiple-choice questions, remove the maximum value and the minimum value and choose one of the two. In previous years, 80.00% of the college entrance examination questions were like this..."

"Damn it." Su Jinci was stunned for a moment, "There can be fucking rules."

After the math get out of class, Zhou Yin went to the bathroom, leaving Shen Changzhou alone to ponder the secret books left by Zhou Yin.

Su Jinci was biting a lollipop in her mouth, and wanted to pull Shen Changzhou out to play with him all the time. Xu Ling was very busy, and only had time to talk to him on the phone at night, why did he not get together before? , I feel that Xu Ling is very free?

Damn, as expected, he didn't cherish it when he got it, so he went to work on a lot of his shit.

Although Su Jinci said so much, he was quite cooperative.

Su Jinci leaned over to Shen Changzhou and said, "It's rare to see you being so serious. Didn't you just slack off wherever you could?"

Shen Changzhou raised his eyes, "This is different."

"What's the difference?" Su Jinci raised her legs.

Shen Changzhou stopped writing and said, "I dare not gamble my future with his."

If I was alone, young and passionate, I would be lucky if I lost, but the two of us are different.

Su Jinci paused for a moment, then stood up and stretched, and slapped Shen Changzhou on the back, "Come in, I'll go pee."

"Trouble." Shen Changzhou dragged the chair forward and let him squeeze out by himself.

Su Jinci walked out of the classroom, and the breeze was blowing in his face. Su Jinci lowered his eyes and thought: Spring is almost here.

During break time, there is a radio in the school, it is "I am a little bird" by Zhuo Yiting

"I wonder if I'm the only one who doesn't have a better tomorrow

未来 会 怎样 究竟 有 会 知道

Is happiness just a legend I will never find out

I am a little bird

I want to fly, but I can't fly high enough

I'm looking, looking, looking, looking for a warm embrace

Is this requirement too high?

......"

Su Jinci turned on the phone, looked at the photo of him and Xu Ling on the desktop wallpaper, and suddenly smiled.

Tomorrow can never be worse.
