Chapter 21 Mathematics Testing
Jiang Chengfeng found a stool on the podium and sat down, his eyes were like eagles, he scanned the classroom, and as soon as someone turned his head and ears, he immediately lectured with a face.
After Ai Xiaoke got the test paper, he began to bury his head in the questions, but Su Yang was not in a hurry, he first scanned his eyes and browsed the entire test paper, and then put pen to paper to do the questions.
He has seen enough questions in the past few days, and the amount of knowledge in mathematics is in the entire third year of high school and the seventh class of students, and he feels that no one can compare to him.
However, because he hadn't done the test papers systematically, he didn't know what his strength was
This test paper is undoubtedly the best item to test his learning results in the past few days.
Originally, he planned to take time in the afternoon to do the mock test papers on the "Five-Year College Entrance Examination Three-Year Simulation", but now that he looks at it, he probably doesn't need it.
Usually, in the subject of mathematics in Jianghai City, the first part of the college entrance examination is fill-in-the-blank questions, while some provinces will test multiple-choice questions first.
There are a total of 12 fill-in-the-blank questions in this paper.
Su Wenfeng's gaze looked at question 1.
"Knowing the set A={(x,y)│x²+y²=1},B={(x,y)│y=x}, then the number of elements in A∩B is. ”
After reading the question, Su Yang's eyes rolled, and the secret path was a scoring question.
In less than two seconds, he was sure of the specific answer: 2.
Why is it so fast, because he has seen similar questions in the "Five-Year College Entrance Examination Three-Year Simulation" before, and there are no less than five, all of which are different in terms of expression, but the idea of solving the problem is roughly the same.
Specifically, A can be seen as a circle x²+y²=1, and B is a straight line y=x.
The question is how many points this circle intersects with this straight line, and a sketch will come out, and the straight line passes through the center of the circle, so there are two intersecting points.
After finishing the first question, Su Yang turned his head to look at Ai Xiaoke, and found that the lesbian table had already done the third question, and the speed was not slow.
Of course, Ai Xiaoke's grades are not bad, and he usually scores more than 600 points in the exam, ranking in the top few of the class, and it is reasonable to be fast.
Without hesitation, Su Yang immediately looked at question 2.
"If a cylinder is known to be 1 in height, and its two bottom sides are circumferred on the spherical surface of the same ball with a diameter of 2, then the volume of the cylinder is . ”
This problem is not difficult, as long as you grasp the center of the sphere at the center of the cylinder, you can list the formula for the radius of the upper and lower bottom surfaces of the cylinder.
It took Su Yang half a minute to figure out the answer.
V=3π/4.
Question 3 tests the second-order determinant and inverse matrix, which is a little more difficult, but not too difficult.
In the following questions, the difficulty gradually increases, and the structural characteristics of the pyramid, the properties of the parabola, the rotating body, the properties of logarithmic operations, the practical application of permutations and combinations, hyperbolas, inverse functions, quadratic coefficients, and so on.
An hour and a half later, Su Yang finished all the questions on this test paper.
To be honest, although he finished it, the questions on this test paper are not simple at all.
If it weren't for the many types of questions that Su Yang memorized, and if it weren't for the integration that made his thinking more active and sensitive, he wouldn't even be able to solve the second question for the last finale.
However, in general, he can basically do these questions.
After spending more than ten minutes and checking it carefully, and finding that there were no omissions or mistakes, Su Yang moved the answers to the fill-in-the-blank questions to the answer sheet.
As for the answer questions, they were filled in as early as the time of answering.
"There are still ten minutes to two hours...... Su Yang took out his Noi 5 and secretly glanced at the time.
I looked up and glanced around the classroom, and found that almost all of them were still struggling to write.
Ai Xiaoke, who was at the same table, had not finished the last question, and was picking at the door of his head with his fingers, biting the pen in his small mouth, frowning slightly, anxiously thinking about the solution ideas.
Su Yang looked at her and felt that she might not be able to think of a solution to the problem like this.
So, he whispered, "Do you want to borrow it from you?"
"Huh?" Ai Xiaoke, who was in his thoughts, was obviously stunned for a moment, turned his head and said in surprise: "Are you done?"
"Well, do you want to see it?" Su Yang nodded and smiled.
"Uh...... Forget it, don't, hehehe......" Ai Xiaoke was stunned and laughed haha.
What are you kidding, copying Su Yang's test papers?
Not to mention the question of whether he can copy it, just take Ai Xiaoke's understanding of Su Yang, and kill her and not do such a stupid thing.
This guy has never passed a 90-point math test once, and copying his test paper is tantamount to suicide.
Of course, Ai Xiaoke admitted that Su Yang had indeed made her feel different in the past few days, and she was studying seriously.
However, the learning method is a bit disagreeable, taking the answers and the questions against each other, one page at a time, one page at a time.
Isn't that foolish?
"Don't forget it. Su Yang was not reluctant.
Soon, the two-hour exam period ended.
Ai Xiaoke's last question still hasn't been solved, and there are still a few questions in front of him that are not accurate, so he filled them in directly.
Jiang Chengfeng stood on the podium and clapped his hands, shouting: "Okay, when the time comes, stop writing and are not allowed to write." ”
Seeing that there were still people writing again, he said in a cold and serious voice: "Stop writing, in the college entrance examination, you don't have a chance to continue writing questions when the time comes." ”
Li Xiang, put away the answer sheets. ”
After receiving the words of the class teacher, Li Xiang, the representative of the mathematics class, stood up and began to collect the answer sheets one by one.
Su Yang opened his ears and heard a lot of complaints.
"Damn, this question is so difficult. One of the top students said bitterly.
"I've just seen the last question, I don't have time...... "One of the middle school students cried with a sad face.
"How many answers do you have to the first multiple-choice question, I got a B, I don't know if it's right?" said a scumbag expectantly.
Someone told him, "I also chose B, congratulations on getting B right." ”
Someone sighed: "To be honest, I feel that this paper is more difficult than last year's college entrance examination, and I feel that I am afraid it will be difficult for me to pass." ”
Someone complained: "Lao Jiang has a convulsion, isn't he deliberately hitting people with such a difficult question?"
……
At the time of the seventh class of high school testing, in the conference room of ET company.
Manager Qi from the network news had a little surprise on his face at the moment.
Not far away, a PPT about "Plants vs. Zombies" was playing on the screen, and Han Qidong was explaining it.
“…… Our game is based on plants resisting zombies, each type of zombie has different characteristics, such as the iron bucket zombie has a strong resistance to hits, and the miner zombie can dig tunnels to bypass the plants planted on the soil surface. ”
"The player's defense against zombies is by planting plants, each of which has a different function, such as the Pea Shooter to shoot zombies, the Sunflower to produce sunlight, the Cherry Bomb to kill all zombies in a certain area, and the Nut Wall to keep zombies in their tracks. ”
"In the course of the game, the player can reasonably grow plants for the weaknesses of different zombies, which is also the trick to victory. ”
"Depending on the gameplay, we also divided the game into five modes: Adventure, Mini, Puzzle, Survival, and Garden, with obstacles such as night, rooftop, fog, and pools, which greatly increased the challenge and made the game almost never-ending. ”
"In addition, in order to increase the stickiness of players, we have also set up personal achievements, such as 'Courtyard Worry' to complete the adventure mode, 'Brainstorming' to break through ten levels in the wireless mode of the zombie public enemy, 'Invulnerable' to successfully defend against twenty waves of ferocious zombies, and 'Everyday Up' to cultivate the wisdom tree to 100 feet ......"
