Chapter 015: Really Attentive

"Xia Lu, it's him again. ā€

Qian Yongbiao made a new cup of tea, stroked his bizarre eyebrows, and then slapped his backhand on the test paper, giving the essay "Kun's Peng, Peng's Kun" a perfect score of 60.

The college entrance examination full-score essay needs to be determined by several marking teachers, Jiangcheng No. 2 Middle School does not have this rule, who is the student in the class, who has the final say.

Qian Yongbiao's eyebrows are very long, and the end of the eyebrows crosses the corners of the eyes, presenting an overall facial shape like this (艹•▽•艹)

Whenever Qian Yongbiao meets Haowen, he will touch his eyebrows intentionally or unintentionally, from the main stem of his eyebrows to the tips of his eyebrows, and take an inverted L route.

Qian Yongbiao pushed down the edge of the table with his hand, fully relying on the law of reaction force and momentum, so that the back chair under his crotch rotated regularly.

After turning around three times leisurely, Qian Yongbiao turned his back to his desk, faced a colleague who was expressionless and close to the level of facial paralysis, and said: "Lao Huang, you came up with the essay question this time, you miscalculated, and a boy in class 35 got a full score." ā€

"Really?" Mr. Huang's facial muscles seemed to have lost their spirituality, and it was impossible to tell whether he was happy or sad, excited or indifferent.

Compared with Mr. Huang, Tim Duncan can be regarded as a facial expression rich in emojis.

"Rolls?" said Mr. Huang spread out his palms.

Qian Yongbiao gave Xia Lu's test paper to Mr. Huang, and Qiwen appreciated it.

Mr. Huang flipped to the composition part and reviewed the composition without smiling, except for his eyes moving, he did not have any other facial activities.

After a while, Mr. Huang returned Xia Lu's test paper to Qian Yongbiao, still in a concise and unfazed tone: "Well written, full marks." ā€

Yoh?

Full score essay?

The other Chinese teachers in the office instantly became active, and they all appraised this essay that was judged by Lao Qian and Lao Huang, who had the highest professionalism, to get a full score.

"Short stories? Okay, this student, he's brave enough. He writes really well, you can give sixty points, or you don't. Teacher Pony commented.

I think this is a great full-score essay, the idea is in line with the topic, the structure is a qualified short novel structure, the story that should be told is clear, if you have to deduct a point, I think the anthropomorphic description is a little stiff, the ingenuity is too heavy, not natural enough. But then again, he's just a high school student, if he can write the characters, plots, and ideas to the extreme within the specified time, in a space of more than 800 words and no more than 1,000 words, is he still a high school student?"

"Xia Lu, this student wrote an essay with a score of 59 last month, this guy has written an essay twice, why didn't he recommend him to participate in the new concept?" said Mr. Liu, his other identity is the tutor of the essay competition of Jiangcheng No. 2 Middle School.

"Xia Lu is a student with great characteristics and is worth cultivating. Qian Yongbiao made a summary and continued to review the examination papers of other students.

……

The Chinese teachers were busy with their business, and the senior students in the exam room entered the math test mode.

It has been more than a week since the last conversation with Teacher Wei Xiaolan, because the time is too short, Xia Lu only found Teacher Wei once after class and asked Teacher Wei to point out his doubts in mathematics.

The only interaction with Mr. Wei only lasted for half an hour.

Teacher Wei can't just favor Xia Lu, she has two classes of math classes, and more than 100 students.

In the college entrance examination math problem solving routine, Mr. Wei told Xia Lu some of it, and the rest depends on Xia Lu's understanding.

What is different from the past is that in this afternoon's math exam, Xia Lu finally got rid of the state of relying on multiple choice questions.

The multiple-choice question is worth 5 points for one question and 50 points for the 10 questions.

In the ancient mathematical masterpiece "Nine Chapters of Arithmetic", the "opening circle" says: the number of square feet of the volume is multiplied by sixteen, nine and one, and the opening square is divided by it, that is, the circle diameter is established. "Open Circle" is equivalent to giving the volume V of a known sphere and finding an approximate formula for its diameter d: dā‰ˆ16/9 multiplied by V and then to the third power. Some similar approximations have been used, based on Ļ€=3.1415926...... Judgment, the most accurate of the following approximate formulas is:

A, dā‰ˆ16/9 multiplied by V and then to the third power

B, dā‰ˆ2V to the third power

C, dā‰ˆ300/157 multiplied by V and then open the cubic again

D, dā‰ˆ21/11 multiplied by V and then to the third power

In the past, Xia Lu must have been blind, either B or C, it was fate to be wrong, and it was fate to bet wrong.

Today, the new summer road is gone.

The weak will gamble, and will have to choose a quarter of the chance of survival.

And the strong, they always take the initiative to grasp the direction of life.

Choosing B, or choosing C, is obviously a dead end.

A is not a good bird either.

The only correct answer is D.

Xia Lu chose D on the answer sheet, and he told himself with great confidence that this time, I got 100% 5 points for this question.

Because, there is this question on the 53 Golden Dictionary, which is the real question of the 2012 Jingchu Provincial Science College Entrance Examination.

This detail fully shows that Xia Lu has really worked hard in mathematics recently.

Poor math scores?

Can I forcibly memorize the representative questions and answers marked with an asterisk on the reference materials?

Yes!

Absolutely!

Not only did he remember the answer, but Xia Lu also remembered the solution idea of "opening a circle". This question is actually not difficult to ponder carefully, according to the volume formula of the ball to find the diameter, the four options one by one, which substitution value is closest to the real value of the π, which is the correct answer. Super simple type of geometry questions.

It's impossible for a dead student to memorize math problems.

Can I memorize all the math problems?

Relying on the three-star brain power of a high school student's powerhouse, Xia Lu did it.

He didn't want to wait to die, he didn't want to be led by the nose by mathematics.

The change in attitude has made Xia Lu no longer afraid of mathematics, in fact, he has understood the true essence of "opening the circle", even if he changes the set of ABCDs, he is sure to calculate the correct answer.

Fill in the blanks, Xia Lu did a few questions, and a few questions were empty.

Calculate the proof question, Xia Lu only did one question.

For this calculation of probability distribution, Xia Lu happened to ask Mr. Wei Xiaolan a similar question.

Through Mr. Wei's explanation, Xia Lu remembered and understood the fixed routine of the probability addition formula.

Everything is a floating cloud, only routines win people's hearts.

Mathematics relies on rote memorization to have a short-term and inefficient effect.

The quickest and most efficient way to improve your math performance is to master the real core skills---- logic and various routines.

Therefore, in the future, I still have to ask my dear teacher Wei more.

Mr. Wei's routines are large and full, and they are very practical.

Xia Lu handed in the papers, and he had never felt so relaxed in the math exam.

Perhaps, my math score this time is still not high, but I Xia Lu defeated my demons, math no longer frightens me, as long as I am proficient in various routines and core techniques, math will eventually be pressed to the floor and rubbed wildly.

……

The first chapter was released so early today, and I shouldn't have gotten up yet.

I do this to tell you that I am an author with a manuscript.

However, the manuscript cannot be used easily, because it must be kept on the shelves.

There are only two shifts a day, please understand (o°ω°o)
