infodatos Chapter 18
Chapter 18
The topic of this composition is called city and countryside.
Of course,
with Xu Mang's insight, he may compare urban life with rural life, and then wantonly lament the great achievements of China's reform and opening up. Basically, he will not get too low scores or high scores if he basically takes such a patriotic road.
Now it's different,
with the help of the system, Xu mang sublimated this composition. To what extent, Xu mang is not clear. In short, it gives people the feeling that they can't understand, but they can feel it is very powerful.
End,
leave.
The hallway of the classroom was full of people. They gathered in groups and began to answer the questions crazily. Some people were excited to face them, and others were crying. They were very sad.
Xu mang has always held a disdainful attitude towards the comparison of the answers after the examination. It used to be like this, but now it is more so. Is it useful for the answers? Can you change the fact that you are wrong if you know it in advance?
No!
It will only make you more sad and sad.
At this time,
lonely Xu mang finds another lonely person in the corner. Yang Xiaoman is in a daze not far away. There are no classmates around her. For a moment, Xu mang feels that the scenery is suffocating.
"..."
"I must be crazy." Xu mang is afraid of this idea just now, and even feels that Yang Xiaoman is so beautiful that she suffocates...
for Yang Xiaoman, she is unpopular. First of all, her arrival breaks the balance of the upper structure of the class and makes some changes in its ranking. This is quite fatal for those school bullies whose heart is higher than the sky.
In particular, the unfortunate man who was squeezed out of the top ten can not be said to hate Yang Xiaoman... To be exact, an unforgettable enemy.
Secondly,
Yang Xiaoman's personality indirectly leads to her strong opposition with the largest number of students. She always shows an expression of rejecting people thousands of miles away. Then she asks her questions and is rejected. As time goes by, Yang Xiaoman is divorced from the masses.
Those bottom learning dregs are ignored.
"Sunset, heartbroken man in the end of the world..." Xu sighed, suddenly wake up, just did a very stupid thing?
Chinese skills - 1
seeing that the value of Chinese skills was deducted a little, Xu mang almost didn't collapse.
Walking toward Yang Xiaoman, Xu mang asked cautiously, "look at your sad face. Did you fail this Chinese exam?"
"Can you talk a little bit about people?" Yang Xiaoman a white eye, said quietly: "this exam is very simple, full score problem is not big, but I deliberately took 149."
"..."
"I said that you boast more than I do!" Xu Mang's face was full of disdain: "you say you are 149 on 149? If you get 149 again, I will eat your paper on the spot
Hearing Xu Mang's words, Yang Xiaoman was slightly stunned and burst out laughing: "this is what you said!"
Xu mang frowns and feels that things are different. This woman seems to be very confident. However, the cow has been blown away by himself. It is impossible to walk. Either it is safe or killed by the cow.
Now it seems that, in all likelihood, they will be crushed to death by their own bulls.
Well,
he died, and at least he was a human being.
...
mathematics is Xu Mang's biggest enemy in his life. Since he bent down, he can't understand mathematics any more... What's more, Xu mang is very confused. Why are there numbers on the math papers? What's more, there are even Greek letters!
As usual,
after getting the paper, he wrote his name and class, which is a sacred ceremony.
What is this?
Collection?
This is a high-end set question that he has never heard of before. There is no number on it. It is full of incomprehensible symbols. Then there are two letters P and s.
Xu mang is wandering at the crossroads of fate. Generally speaking, the first question of multiple-choice questions is a free gift, but otherwise... It is just a waste of life.
A?
It doesn't look like it!
B？
Lack of a sense of attraction.
D？
No soul.
Xu mang finally chose C, there is no reason, anyway, it is life and death, right or wrong in the sky!
Generally speaking, there is a rule in any blank filling problem. It is to find the most marked one from the length of the options, such as the longest or the shortest, but if two are long and two are short, then select b, and if there is no rule, choose C.
In fact, this law is out of date.
Xu mang used to be a believer in this law, and got good marks, until the teacher learned to reverse the routine... According to this law, they worked out the problem in reverse, and even five consecutive A's would appear.Apart from the level of Xueba, when Xuemin and xuezhuo encounter the same option in the fifth company, they first doubt whether they are wrong. Under such strong hint, they will be forced to make changes to achieve the final balance of options.
At this time, Xu mangmeng finished multiple-choice questions and came to fill in the blanks. Unlike other blank filling problems in other subjects, the others only need memory. You can use it here... Function image, conic curve, function and derivative, etc. each type of question gives Xu mang a suffocating experience.
Xu mang has already hung up...
bypass!
Calculation questions...
sorry, bypass again!
Answer question...
this can be!
Xu Mang in each of the solutions, wrote a word, this is the solution to the problem at least respect.
The first problem is trigonometric function. As one of the most basic elementary functions, it is a function with angle as independent variable, angle corresponding to arbitrary angle and intersection coordinate of unit circle or its ratio as dependent variable. Generally, sine, cosine and tangent are used.
But...
it's too difficult for Xu mang!
I can't remember the special angle, I can't draw the function image, and I don't know the induction formula at all. Forget it, this problem is empty.
The second question, about probability and statistics, is the most basic question of giving points. However, Xu mang only took a look at it, and then went to a new battlefield.
as like as two peas or a conic curve wrecker, he did not do anything. Xu ran into the mathematics examination paper. In general, this is the battlefield of learning tyrants. All the subjects in front of them can be exactly the same. The only difference is here.
This is a problem about derivative. This kind of topic generally inspects the comprehensive strength of students, and its content is far beyond the content of textbooks. Its concept involves a wide range, such as monotonicity, non monotonicity, extreme value, extreme point, maximum value, etc.
According to common sense, Xu mang will give up, but now it is different, he chooses to face the difficulties!
Just imagine,
the front is basically blank, but the most difficult big problem is solved. Does this mean that the blank in front has a chance to explain?
Look!
The most difficult major problems have been solved, and the front is just unwilling to do it.
"System, how many points does it take to solve this problem perfectly?"
[through systematic identification, the exchange value of the perfect solution process: 100 (mathematical skills)]
Xiaogui,
the full score composition of Chinese test paper only needs 300 skill value, but people give 60 points, this math problem only gives 12 points, and it needs 100 skill value...
but you can't think about problems like this. You can have several chances to pretend to force in life, and you will miss less once Once.
Pay!
