Chapter 72 Countdown: 0 Days

2014 6 Month 7 Day.

China's annual college entrance examination conference officially kicked off.

7:00am.

At the entrance of the test center of Wanxi No. [-] Middle School, a cordon has been drawn up, and police cars are already guarding the road outside the school.

During the college entrance examination, all vehicles passing the examination area are prohibited from honking their horns.

At this time, the private cars passing by already had a tacit understanding, and they all passed slowly, and none of them roared in a hurry.

Everyone understands that these two days are likely to decide a person's life.

And whoever does not have children, will be heart-to-heart, and everyone will fully cooperate.

As the time approached, the candidates came to the school gate one after another.

Some candidates waved goodbye to the parents who came to take the test. After entering the school, their parents were still looking inside the school with their heads stretched out.

As for Chen Zhou and the others, they were notified by Li Dabiao last night.

At 7:30 in the morning, come down for breakfast, 30 minutes breakfast time.

After eating, rest for another 10 minutes, and go to the examination room on time at 8:10.

Never be late.

At 8:20 in the morning, Li Dabiao led a group of students to the gate of Wanxi No. [-] Middle School.

I simply ordered two sentences, don't be nervous, you must see the question clearly, do not rush the question, put it away first, and so on and so on.

After about 5 minutes, Li Dabiao stopped talking and sent the students to the school.

Chen Zhou came outside the examination room, put his backpack on the table outside the classroom, and entered the examination room with the necessary stationery.

At this moment, a trace of tension appeared in Chen Zhou's heart.

After he came to his seat and sat down, he tilted his head slightly and looked out the window.

Looking at the already lush white poplar outside, Chen Zhou's mood gradually calmed down.

Sometimes, Chen Zhou was very fortunate that he was assigned a window seat during the exam.

Looking out the window before an exam is a great way to soothe your mind.

10 minutes before the test, the invigilator began to announce the discipline of the test room and some precautions.

Then display the sealed portfolio bag, start unpacking, and send out the test paper.

After getting the test paper, Chen Zhou first checked the test paper to confirm whether the test paper was damaged or illegible.

Then fill in your information on the test paper and wait silently for the password to start answering the questions.

When he couldn't write to answer the question, Chen Zhou turned the test paper to the Chinese composition question.

Look at the topic first, choose the angle, determine the idea, and write it directly later.

This year's Chinese composition title is a material composition.

The material composition is the most well-established way of questioning among the composition questions.

Chen Zhou read this material carefully and said that it was the difference of opinion between the actor and the screenwriter.

The actor said that the lines of the script can be changed according to the actual situation.The screenwriter believes that the script is the foundation of a play and cannot be changed at will, otherwise the words may be unintelligible.

After reading it, Chen Zhou thought about it, there are too many aspects that can be written in this material, whether it is from the perspective of the actor or the perspective of the screenwriter.

But if you want to get a high score, you can't just think about the problem from one perspective, you need a dialectically unified perspective.

The actors in the material represent innovation, and the screenwriters represent inheritance. We can talk about the relationship between cultural inheritance and innovation based on reality.

After thinking about this, Chen Zhou finalized the perspective and intention of this composition.

Time came to 9:00, answer the questions, start.

Chen Zhou read the composition materials again, and after confirming that there were no problems, he began to write.

The college entrance examination has officially begun.

All the candidates for the college entrance examination began to write and write the answers to the questions for their own goals.

At this time, on the campus of Maochang High School, an old man was walking out of the vacant teaching building.

The old man held a chalk and an eraser in his hand. With these two things, he had already walked through all the college entrance examination classes.

Every time he went to a classroom, he went to the blackboard at the back of the classroom, erased the "2" in "Countdown: 2 Days" on the blackboard with the eraser, and then wrote "0" with the chalk in his hand.

After doing this, recite one more sentence: "Children, come on for the college entrance examination."

After that, he walked out of the classroom and went to the next classroom.

This steadfast old man is the principal Zhu of Maochang High School.

The students went to Wanxi City to prepare for the college entrance examination on the 5th, and no one recorded the countdown.

Therefore, he took on this job and used this method to accompany the students to the college entrance examination.

For this extra work, and for the cheers not to be later than the start of the college entrance examination, Principal Zhu started to shuttle between the classrooms at 6:30 in the morning.

The language test is still going on. After Chen Zhou finished writing the composition, he has already completed the question of writing famous sentences.

The requirement of this question is to choose one of the two questions A and B to answer.

Chen Zhou glanced at it briefly and chose question A.

Title A is a classic passage in "Mencius: Gaozixia", which almost everyone can memorize.

"Therefore, when the heavens will give great responsibilities to people, they must first suffer their minds and wills, labor their muscles and bones, starve their bodies and skin, empty their bodies, and disturb their actions.

Chen Zhou first recited in his mind, then wrote the answer on the original question sheet of the test paper, checked it again, and confirmed that there were no typos before transcribing it on the answer sheet of the test paper.

Because every wrong word in the space will lose points, so Chen Zhou was extra serious when filling out the answer sheet.

As a result, his speed of answering questions is slightly slower than before.

Fifteen minutes before the end of the Chinese test, Chen Zhou checked it twice before getting up to hand in the paper.

During the lunch break, Chen Zhou, Zhang Yifan, and Chen Haining maintained a tacit understanding and did not ask each other how the exam was going.

Chen Zhou did not take the wrong question set to evaluate the score, and he will wait until the test is over.

At 2:00 pm, the math test starts on time.

Before the exam, when browsing the exam papers, Chen Zhou felt that the exam papers this time were okay.

Sure enough, last year, that is, the 13-year test paper, after all the candidates wept bitterly, they finally found their conscience.

After all, last year's test papers were created by a good person, and this year it is not a good person who decides the questions.

However, as a sister paper for 13 years, in order to swear to exist, Niu Ren still came up with a very difficult final question, which is the 21st question.

The title is [Assume the real number c>0, the integer p>1, n∈N*]

【（1）证明：当x＞-1，且x≠0时，(1+x)^p＞1+px】

【（2）数列｛an｝满足a1＞c^(1/p)，a(n+1)=[(p-1)/p]an+(c/p)an^(1-p)。证明：an＞a(n+1)＞c^(1/p)】

After reading the question, Chen Zhou's first reaction was, isn't this knowledge of advanced numbers?Proof of monotonicity and boundedness of series?Is it over the top?
After reading the question again, Chen Zhou analyzed it. This question probably examines mathematical knowledge and methods such as functions, series, inequalities, analytical methods, and comprehensive methods.

Chen Zhou first used the method of the constructor, obtained the derivation and then used the monotonicity of the function to prove the question (1), which is quite simple.

Question (2) can be asked.
Chen Zhou thought for a while, and first checked the calculation on the draft paper, starting from a(n+1)>c^(1/p), and using the given known conditions, he converted the proof formula into an equivalent to solve this problem. question.

He did not choose to use the knowledge of advanced numbers.

Soon, with constant thinking, Chen Zhou proved a(n+1)>c^(1/p).

Then in the same way, convert an>a(n+1) to prove it using the proved conclusion.

After completing all the calculations on the draft paper, Chen Zhou sorted out the steps and began to write on the answer sheet.

".To sum up, an>a(n+1)>c^(1/p), the original inequality is proved."

After writing the last sentence, Chen Zhou completed the answer to the math test paper.

　Thank you~
