The man who turned the times

Chapter 20 Math Tests
Jiang Chengfeng found a stool on the podium and sat down, his eyes were like a falcon, scanning the classroom.

As soon as someone whispered to each other, they immediately reprimanded them.

After Ai Xiaoke got the test paper, he started to concentrate on the questions, but Su Yang was not in a hurry. He glanced through the whole test paper first, and then took up the pen to do the questions.

He has read enough questions in the past few days, and he has a reserve of mathematics knowledge. Among the students in the third and seventh classes of high school, he feels that no one can match him.

However, because he didn't do the test papers systematically, he still doesn't know how strong he is

This test paper is undoubtedly the best item to test his learning results in the past few days.

Originally, he planned to take some time in the afternoon to do the set of mock test papers in the "Five-Year College Entrance Exam and Three-Year Simulation".

But looking at it now, it probably doesn't matter.

Usually, for the subject of mathematics in Jianghai City, during the college entrance examination, the first part of the test is to fill in the blanks, while in some provinces, multiple-choice questions are taken first.

There are 12 fill-in-the-blank questions in this test paper.

Su Wenfeng looked at the first question.

"It is known that the set A={(x, y)│x+y=1}, B={(x, y)│y=x}, then the number of elements in A∩B is."

After reading the questions, Su Yang rolled his eyes, and secretly said to send sub-questions together.

In less than two seconds, he confirmed the specific answer: 2.

Why so fast, because he had seen similar questions in the "Five-Year College Entrance Examination and Three-Year Simulation" before, and there were no less than five questions. They were all different, but the ideas for solving the questions were roughly the same.

Specifically, A can be regarded as a circle x+y=1, and B is a straight line y=x.

The question is how many points where the circle and the line intersect. After drawing a sketch, the line passes through the center of the circle and there are two intersecting points.

After finishing the first question, Su Yang turned his head and glanced at Ai Xiaoke, and found that the girl at the same table had already done the third question, and the speed was not slow.

Of course, Ai Xiaoke's grades are not bad in the first place. He usually scores above [-] in the exams, ranking among the top few in the class, so it is reasonable to be fast.

Su Yang looks at question 2.

"It is known that the height of a cylinder is 1, and the circumferences of its two bases are on the spherical surface of the same sphere with a diameter of 2, then the volume of the cylinder is ."

This question is not difficult, as long as the center of the sphere is in the center of the cylinder, the formula for the radius of the upper and lower bottom surfaces of the cylinder can be listed.

Su Yang calculated the answer in half a minute.

V=3π/4.
The third question is the second-order determinant and inverse matrix, which is a little difficult, but not too difficult.

The next questions gradually increase in difficulty.

The structural characteristics of pyramids, the properties of parabolas, solids of revolution, the operational properties of logarithms, the practical application of permutations and combinations, hyperbolas, inverse functions, quadratic coefficients, etc. are tested.

After an hour and a half, Su Yang finished all the questions on this test paper.

To be honest, even though he finished it, the questions on this test paper were not easy at all.

If it wasn't for the many types of questions that Su Yang memorized, and if it wasn't for his thinking being more active and sensitive due to his mastery, he wouldn't even be able to solve the second question for the final question.

However, in general, he can basically do these questions.

It took more than ten minutes to check it carefully, and found that there were no omissions or mistakes. Su Yang moved the answers to the fill-in-the-blank questions on the answer sheet.

As for the answers to the questions, they were filled in as early as when answering the questions.

"It's only 10 minutes until two hours..." Su Yang took out his Noi 5 and secretly glanced at the time.

Looking up, I glanced around the classroom, and found that almost everyone was still scribbling.

Ai Xiaoke, who is at the same table, still has the last question to finish. She is digging her forehead with her fingers, biting the pen holder in her small mouth, frowning slightly, anxiously thinking about the solution to the problem.

Su Yang looked at her and felt that she might not be able to think of a solution to the problem.

So, he whispered: "Do you want to borrow it from you?"

"Huh?" Ai Xiaoke, who was in her thoughts, was obviously taken aback for a moment, then turned her head in surprise and said, "Are you done?"

"Well, do you want to watch it?" Su Yang nodded and smiled.

"Uh...forget it, don't, hehehe..." Ai Xiaoke was stunned, and laughed.

Copying Su Yang's test paper?

Not to mention the question of whether they will copy or not, taking Ai Xiaoke's understanding of Su Yang, she would not do such a stupid thing if she was killed.

This guy has never passed the math test with a score of 90. Copying his test paper is tantamount to self-destructing.

Of course, Ai Xiaoke admitted that Su Yang gave her a different feeling these days, and she was studying hard.

However, the learning method is a bit unbelievable. I took the answer and the question to compare and browse, one page at a time, one page at a time.

This is not a whole thing.

"Don't forget it." Su Yang didn't force it.

Soon, the two-hour exam time is over.

Ai Xiaoke still hasn't solved the last question, and there are still a few questions that are not sure about the choice and filling in the blanks, so she just filled in randomly.

Standing on the podium, Jiang Chengfeng clapped his hands and shouted: "Okay, the time is up, everyone stops their pens and no writing is allowed."

Seeing that there were still people writing again, he said in a cold and serious voice, "Stop your pens, in the college entrance examination room, you have no chance to continue writing questions when the time is up."

"Li Xiang, collect all the answer sheets."

After receiving the words from the head teacher, Li Xiang, the math class representative, stood up and began to collect the answer sheets one by one.

Su Yang opened his ears and heard a lot of mourning.

"This question is so difficult." A top student said distressedly.

"I just saw the last question, I don't have time..." A mid-level student was crying.

"How much did you answer the first multiple-choice question? I got a B. I don't know if I'm right?" A scumbag spoke expectantly.

"I also chose B. Congratulations, you got B right."

"To be honest, I feel that this paper is more difficult than last year's college entrance examination. I feel that it will be difficult for me to pass."

"Lao Jiang is having a fit, isn't he afraid of leaving us with a psychological shadow when he asks such a difficult question?"

……

In the meeting room of ET Company during the test in Class [-] and [-] of Senior High School.

Manager Qi from Netcom had a look of surprise on his face at the moment.

Not far away, a PPT about "Plants vs. Zombies" is being played on the screen, and Han Qidong is explaining it.

"...Our game is based on plants resisting zombies. Each zombie has different characteristics. For example, iron barrel zombies have strong resistance to attack, and miner zombies can dig tunnels to avoid plants planted on the soil surface. wait."

"The way players defend against zombies is to plant plants. Dozens of plants each have different functions. For example, pea shooters can shoot zombies, sunflowers can produce sunlight, cherry bombs can kill all zombies within a certain range, and nuts Walls can block zombies with high durability."

"During the game, players can grow plants reasonably according to the weaknesses of different zombies, which is also the key to victory."

"According to the different ways of playing, we also divide the game into five modes: adventure, mini, puzzle, survival, garden, with obstacles such as night, roof, dense fog and swimming pool, which greatly increases its challenge and makes The game is nearly never-ending."

"In addition, in order to increase the player's stickiness, we also set up personal achievements, such as 'Worry in the Garden' needs to complete the adventure mode, 'Brainstorm' needs to break through ten levels in the wireless mode of Zombie Public Enemy, and 'Invulnerable' needs to successfully resist two levels. Ten waves of ferocious attacking zombies, 'day up' needs to grow the tree of wisdom to one hundred feet..."
