Chapter 108
Chapter 107 No pressure, even 1 point to cry
There is not much time to ask questions, because the college entrance examination is still in progress.
After the morning Chinese test was over, Shen Qi and his parents went home directly. After a little adjustment and rest, he had to take another test in the afternoon. There will be two exams tomorrow.
Shen Qi didn’t know where his classmates took the college entrance examination, in which middle school and which classroom?
Shen Qi hopes that Chen Xiaoting and Gu Xiaodan can get ideal scores. He will never contact them for these two days. He will not contact anyone. The mobile phone has been turned off and will be turned off for two consecutive days.
It can be said that Shen Qi did his best to respond to the college entrance examination, not for anything else, but for a miracle vigorously, who made me have a strange word in my name.
At three o’clock in the afternoon, the second subject of the college entrance examination will start.
Compared with Chinese, the second college entrance examination subject has no pressure on Shen Qi.
The second test is mathematics.
The question types of mathematics are not as complicated as those of Chinese. There are three types: multiple-choice questions, fill-in-the-blank questions, and short-answer questions.
The full score of Yushuying is 50, and the full score of Lizong/Wenzong is 300. Shen Qi and his colleagues use this model for the college entrance examination.
Set, arithmetic sequence, three-dimensional geometry view, block diagram, inducing formula, trigonometric function image transformation… 2 multiple-choice questions are not even pediatrics for Shen Qi. He solves one multiple-choice question in 20 seconds on average.
After all, it is the college entrance examination, so we must be cautious and cautious.
If it is normal, Shen Qi can solve a problem in 0 seconds.
It took a little more than four minutes for Shen Qi to finish all the multiple-choice questions.
Fill-in-the-blank questions are equally vulnerable.
The calculation of plane vectors, the application of linear programming, the nature of hyperbola, the volume of geometric bodies… they cannot escape the fate of being destroyed.
Shen Qi completed four fill-in-the-blank questions in 3 minutes and made some simple calculations on the draft paper.
Within 8 minutes, Shen Qi finished the multiple-choice and fill-in-the-blank questions.
The highlight of the college entrance examination math papers is of course the short answer questions.
Short answer questions are generally divided into calculation questions and proof questions.
Regardless of whether it is a calculation question or a proof question, for Shen Qi, it is a sub-question.
Short answer question first question:
“The known function f()=-^2+a+4, g()=|+|+|-|.”
) When a=, find the solution set of the inequality f()≥g();”
2) If the solution set of f()≥g() contains [-,], find the value range of a.”..
2 points for this question.
“These sub-questions, the sub-submissions have no technical content.”
Shen Qi didn’t even have a chance to write a draft, so he solved it directly on the test paper.
Very quickly, he solved the solution set of f()≥g() as:
{|-≤≤-+√【7】/2}
(√【】represents the root sign, for example √【7】 means there is a 7 under the root sign, the same below)
The first question is solved in this way, it is not as good as a fill-in-the-blank question, at least the last question is more difficult than it.
The second question continues to send points.
Shen Qi quickly found that the value range of a is [-,].
What do you mean, do the two questions of the first short answer question give 2 points for nothing?
The knowledge points used are nothing more than removing the absolute value between the partitions, solving the inequalities separately, and taking the union set as the solution set of the original inequality… and so on the most basic high school mathematics knowledge.
The next few short-answer questions are the normal distribution to find the mathematical expectation, the positional relationship between the straight line and the conic section, the parameter equation…
Send points to send points, continue to send points.
More than 20 minutes passed, and Shen Qi completed the 3-point problem.
Shen Qi didn’t use any super-class knowledge, and he was like bullying elementary school students, which shows that this math test paper for the college entrance examination is simple to compare.
“What’s so special? You can get above 40 in the test?” Shen Qi is speechless. If mathematics is so simple, is it still called mathematics?
After all the tests, I still enjoy it. That battlefield is the battlefield of real men.
“The most boring subject for the college entrance examination is mathematics.”
Shen Qi was very disappointed, especially worried, and even about to lose the last trace of passion.
But there is no way. This is the college entrance examination. Shen Qi must continue to be bored and complete the math test papers.
The last finale is a function question, 4 points.
Generally speaking, the last question in the mathematics examination papers of all provinces across the country is the most difficult.
“The finale, please don’t let me continue to be disappointed. The whole math test paper is like this. Even if I get a perfect score, what is the essential difference from other candidates?”
“The finale of the Chinese essayist has some finale temperament anyway, and you, mathematics, and my master talent, don’t let me disappointed or disappointed in you.” Shen Qi began to examine the questions carefully, the finale of the function questions.
The title of the last question is:
“The known function f()=/√[+]+/√[+a]+√[a/a+8], ∈(0, +∞).”
At this point in the trial, Shen Qi’s heart was cold, abolished, and not a chieftain.
Looking at this topic, you know that it is not a good bird.
A properly weak chicken.
It was so simple that Shen Qi wanted to cry.
The first question is: when a=8, find the monotonic interval of f().
“Sure enough…” Shen Qi felt cold.
Interesting, funny, the simplest math papers for the college entrance examination in history are freshly released.
Everyone can get a full score. Don’t miss it if you pass by.
Distraught and disappointed, Shen Qi’s first question in solving the final math problem:
When a=8, f()=(+√【】/√【+】)+/3
Find: f'()=-√【】/2√【(+)】
Therefore, when ∈(0,], f'()≥0;
When ∈[, +∞), f'()≤0
So f() increases monotonically in (0,], and decreases monotonically in [,+∞).
The knowledge points examined in this question are very basic, that is, the nature and application of functions, as well as the solution and application of inequalities.
“I want to cry, I really want to cry.” Shen Qi frowned, the May 3 questions were whitewashed, and my math book was written for nothing, fake, all fake.
If you do this kind of question for you, just ask if you cry or not?
You may not cry, or even want to laugh a little.
But Champion I almost cried out, but fortunately, Shen Qi relied on strong willpower to hold it back.
This math test paper for the college entrance examination was too chilling for Shen Qi. The first question of the finale, let alone me, even Chen Xiaoting can easily handle it. Chen Xiaoting may not be able to get full marks in the test.
“Ha ha ha…” Shen Qi smiled inexplicably, with bitterness in his smile.
The invigilator was taken aback, and when it was over, he lost his mind in the exam, which was obviously neurotic.
This kind of thing is not uncommon in the college entrance examination examination room Hey, that’s right, the candidate whose exam number is 00, the name Shen Qi, seems to be familiar with each other, he won’t be that Olympiad champion, right?
The Olympiad champions are all stupid?
This math test paper is too difficult!
The invigilator continued to pay attention to Shen Qi’s dynamics.
“Huh…” Shen Qi took a deep breath, having to calm himself down.
Fortunately, the second question of the finale made Shen Qi a little bit happy.
The second question is: For any positive number a, prove:
The second question is, I don’t know which professor made it. This technique… is a bit like the tune of a number competition.
Shen Qi regrouped, and he entered the second question vigorously, which was also the answer to the last question of the math test paper for the college entrance examination…
