Chapter 484: Junior high school difficulty of liberal arts and mathematics, college difficulty of science and mathematics (monthly ticket plus updates)
After entering the examination room, the seats for today's examination were readjusted.
Candidates from liberal arts and science subjects sit together.
And everyone got a message.
This year's liberal arts mathematics test paper is different from the science mathematics test paper.
Science students are surrounded by liberal arts students, and liberal arts students are surrounded by science students.
In this way, even if you have good eyesight, you won't be able to copy it if you want.
Eliminates the possibility of cheating.
Then there were two new invigilators today, one holding the liberal arts test paper and the other holding the science test paper. After explaining the discipline and precautions in the examination room, they began to distribute the test papers.
Even before today's paper came down, I could clearly feel that the whole atmosphere was different from the first day.
If it was an appetizer yesterday, it feels like a meal today.
It is the final exam.
If you don’t take the English test tomorrow and take the English test tomorrow, you will have completed the college entrance examination if you finish the test today.
I don’t know if such a strict style was prepared long ago or because of what happened yesterday.
After Fang Yan got the test paper, before he started reading it, he heard the invigilator say:
"Candidates should pay attention to their own test papers. Don't take the liberal arts ones as science ones. If you take the wrong test paper, quickly raise your hand and change it."
Fang Yan glanced at his test paper and saw that it said liberal arts was correct.
There was no wrong test paper issued.
It's just that the difficulty of the above questions made him somewhat unexpected.
All of them were junior high school difficulty test questions.
Only the last pull question is slightly more difficult.
The title is:
It is known that the quadratic function y=x-6x+5.
(1) Find the vertex coordinates and symmetry axis equation of its image;
(2) Draw its image; the vertex and symmetry axis formulas of the quadratic function will use the point drawing method to draw the function image.
(3) Find the intersection coordinates of its image and the x-axis and y-axis respectively,
The test point is the image of a quadratic function, which is a comprehensive question on graphing.
After Fang Yan saw this sub-question in his mind, the corresponding problem-solving logic immediately appeared in his mind:
The first question only needs to be solved based on the vertex coordinate formula and the symmetry axis formula of the quadratic function.
For the second question, just draw the function image according to the steps of listing, drawing points, and connecting lines.
The third question is to set X=0 to find the corresponding Y value, write the intersection point of the coordinates with the Y-axis of the function image, set Y=0 to find the corresponding intersection point.
It can be seen from this question that the purpose of this question is to test students' mastery of the vertex and symmetry axis formula of a quadratic function, their ability to use the point tracing method to draw the function image, and find the intersection coordinates of the function image and the coordinate axis.
This sub-question was guessed by Fang Yan and the others last night.
But because they thought it was not too difficult, they didn't pay too much attention.
At this time, Fang Yan even felt that this was not a score-pull question.
Then read the previous questions again.
It turned out that this was still the most difficult.
Isn't it...the current mathematics in liberal arts only tests junior high school level stuff?
Is liberal arts too boring?
Thinking of this, he wanted to see the mathematics problems of science students.
He had a good eye and glanced at the math test paper for science students next to him.
Fang Yan was stunned for a moment by the content on the test paper. It was actually college mathematics content. The difficulty of the questions at the end of the test paper seems to be comparable to the score-breaking questions in liberal arts.
Especially in the last step, it has begun to appear: using ε-δ language to describe the continuous definition of function f(x) at the point x=x0.
Although it was not a problem for dialects, he could clearly feel the huge gap in difficulty between the two sets of test papers.
Compared with the ease of the liberal arts mathematics test paper, the difficulty of the science mathematics test paper is like hell mode.
At this time, Fang Yan was already wondering whether the Chinese language test paper for the afternoon liberal arts also had this hellish pattern.
At this moment, Fang Yan could clearly feel that the expressions of the surrounding science students were not good.
I probably thought it would be difficult, but I didn’t expect it to be this difficult.
At least it's different from the style of yesterday's test paper.
There was only one pull-point question in yesterday's test paper, but today's test paper gave them the feeling that the second half of the paper was full of pull-point questions.
At this moment, some people are already calculating how many points will be deducted for the questions they cannot do.
At this time, the invigilator handed out the test papers and said to everyone:
The latest chapter of this book
Take a look at the 16-9 book bar!
"Don't look around. Pay attention to your test papers. If there are any errors, report them quickly and replace them. Start answering the papers as soon as the exam bell rings."
Everyone fell silent and began to read the questions on the test paper.
Fang Yan also withdrew his gaze and read all the questions on his test paper. At this moment, all the answers had appeared in his mind, and there were no questions that you couldn't understand.
As the bell rang outside, the invigilator announced that the test could begin.
In the simple mode of mathematics for liberal arts students, everyone did it very quickly.
But when it came to the last question, many people were still stumped.
The science students were doing the questions as if they had passed one level, and the next level was more difficult waiting for them. Their expressions were solemn, which was in huge contrast to the relaxed expressions of the liberal arts students.
Fang Yan wrote vigorously and without any pause, writing the answers one by one on the test paper.
Today's new invigilator also noticed him.
Seeing that he wrote smoothly and without any pause, the invigilator was also a little surprised. Although the liberal arts questions were relatively simple, they were not so simple that they could not be paused at all, right?
After walking around Fang Yan, the invigilator found that all the answers had been written on Fang Yan's test paper.
The handwriting is neat without any alteration, the problem-solving ideas are clear, and all the answers are completed in one go.
Even though the mathematics test paper for liberal arts is relatively simple, the invigilator has never seen anyone who can do it like him.
The two invigilators took turns to look at his test paper behind Fang Yan's back, and then exchanged silent glances. They both saw praise in each other's eyes. Just this clear and fast way of solving problems is not something ordinary people can have.
It's just a pity that he didn't get the more difficult science and mathematics test paper, otherwise it would be possible to see whether he can achieve what he is now.
Fang Yan finished his test paper and was observing others.
Here, if you know something like mathematics, you know it, and if you don’t know it, you don’t know it. Some people’s faces turned red and their dandruff came out, but they still didn’t have the answer.
Of course, there are also some people who suddenly figure it out and write furiously with excitement on their faces. This is a kind of person who suddenly enlightens in the examination room and performs extraordinarily well in the exam. It is a kind of rare thing that can only be encountered. state.
However, Fang Yan is somewhat fortunate that his younger brother and older sister majored in liberal arts.
In this case, I can't give them any trouble with these questions.
Especially my little brother's shortcomings in mathematics, at this level of difficulty, it's not a problem at all for him.
As long as there are no glitches in the Chinese language test in the afternoon, their entrance to Peking University should be a sure thing.
PS: The monthly ticket has increased by 100, so after finishing this chapter, I still owe you 20,000 words.
Just got home, there will be a chapter later.
