Zhang Xingxing was very satisfied with the performance on the first day of the college entrance examination, and on the whole, he felt very good about the performance of the college entrance examination on the first day, and he lived up to the three-year preparation.

Except for the question of the Minister of Foreign Affairs in the final political subject exam, he really couldn't find a way to blind the name of a hundred families on the scratch paper, and then ticked Huang and filled in a Minister Huang, Zhang Xingxing felt that he should answer the other questions well.

After the first day of the exam, Zhang Xingxing lived in a small guest house in Dongyang County, which was arranged by the county for the college entrance examination, a large number of college entrance examination candidates poured into Dongyang County, and those guest houses in Dongyang County could not digest it at all, so a room was opened to sleep, and there were seventeen or eighteen people in the room where Zhang Xingxing lived, and everyone could really just find a place to sleep.

In the guest house, these college entrance examination students naturally talked about that political topic.

Who is the Minister of Foreign Affairs, someone went to the newspaper office and bought the international newspaper.

Scold!

Zhang was happy, he seemed to be a blind cat who had met a dead mouse, that was really Minister Huang, but he just answered a surname, and I didn't know how many points the teacher would give.

The guest house was too crowded and there were so many people.

And there are not so many beds, and the hard work of making the floor in the winter is more difficult than sleeping in the basement in the future life.

But there is resentment in sleeping in the basement, but now there is none, everyone sleeps like that in this era, and everyone can make do with it without comparison.

Night.

Zhang Xingxing was restless in the middle of the night, all kinds of snoring and snoring came and went.

I feel like I'm going crazy.

If you don't let my old man sleep, you don't want to sleep so peacefully.

Old man Zhang's belly was dark, and his foot touched a porcelain basin on the washstand.

Then secretly retract his feet and pretend to be asleep.

The washstand is wobbly.

Finally unstable.

"Bang dang!"

......

Many people in the room were scared to wake up, and many people were not woken up by the porcelain basin, but they were also woken up by the shouting of babbling.

"What's wrong!"

"Earthquake?"

"Are you going to start math?"

......

Fought several times.

In the second half of the night, Zhang Xingxing couldn't stay up, and then fell asleep.

With half a panda eye, Zhang Xingxing stepped into the first exam of mathematics today.

1997 Mathematics Examination for Higher Education Admissions.

Question 1:

Solving inequalities|x|<5.

This question is simply a score question.

"Brush"

-5

I'm afraid that students in this era don't know what the absolute value is, or don't consider the fact that x is greater than -5, and then don't get a score for this question.

Because if it's only x<5, it's obviously wrong. -8 is less than 5, but its absolute value is definitely greater than 5, this junior high level of mathematics, even if you send points in this era, many people will not get points.

Zhang Xingxing is very happy, usually do math feeling big, I didn't expect this math problem to be much easier than he imagined, originally he planned to do a little better in other courses, this math can be tested a few points on the attitude, but up to get eight points, a good start.

Question 2:

In response to the great call for "greening the motherland," the advance brigade planted 200 mu of afforestation in 1975, and also knew that a total of 728 mu of afforestation was planted in the three years from 1975 to 1977.

This is an application problem, and at first glance it can only be solved by equations, because I don't know how much was planted in 1976 and 1977.

Let's assume that one of them is x and the other is y, because it is to find the average annual growth rate, that is to say, the number x and y are not important, the average annual growth rate is the same, so that you can get a few equations and then calculate the average annual growth rate.

Solution: Set up x acres of afforestation in 1976 and y acres of afforestation in 1977.

Then: X+y+200=728

x/200=y/x

According to the commutation method, x=528-y

Substituting the second equation gives (528-y)/200=y/(528-y)

This is a quadratic equation of one element.

But the number is so big, after a long time, Zhang Xingxing vomited blood.

......

The third question is to verify the Pythagorean law.

This question Zhao Gaohong taught Zhang Xingxing.

In the examination room, I remembered that Nizi was here, did she know that she was in the college entrance examination, and she wrote a letter for half a year without replying, Zhang Xingxing was busy reviewing, and was busy with the process formulation of the wood carving factory of the construction society, so she didn't have the strength to write to her again.

At that time, she taught Zhang Xingxing three proofs, although there are more than a dozen proofs of the Pythagorean law, Zhang Xingxing felt that learning three was already very powerful, he chose to use a b as the right angled side, and c as the hypotenuse to make four congruent right triangles, then the area of each right triangle is equal to one-half ab.

Because AEB three points are in a straight line, BFC three points are in a straight line, and CGD three points are in a straight line.

The Pythagorean theorem can be deduced by proving that the quadrilateral EFGH is a square with a side length of c.

Recovering from missing Zhao Gaohong's distraction, Zhang Xingxing finished answering the proof of the Pythagorean theorem in a bit of a trance.

Then I looked at the math problems in the back and felt that the problems were a lot better.

Question 4: Decomposing factors.

The fifth problem is to find a system of equations.

The sixth problem is to find the derivative.

The seventh question is geometric proofs

The eighth question is the eighth question, and the ninth question is to find the limit, and the tenth question is proved with definite integrals, and the math problem feels really a bit too much.

Then Zhang Laohan saw that there was still the ninth and tenth, and there was a small desertion in the brush, and he did the question directly with acceleration, but the question felt bigger and bigger, and it was still stuck.

In addition to Zhang Xingxing's jam in the examination room, the national college entrance examination mathematics is stuck, how to prove the Pythagorean law, the annual growth rate can definitely be calculated, the planting area in 1976, and the planting area in 1977 are not known at all.

Liberal arts candidates, the collapse of a large area of mathematics subjects, and the mathematics of science makes it impossible for candidates to find the north, and it is a large complex of parabolic functions, and the parabola is a problem, and it is difficult to add, for the first college entrance examination candidates who usually have no training, it is simply a collapse.

Question 9, question 10, Zhang Xingxing racked his brains, but he still didn't know where to start, it was too difficult, and he suddenly saw that he had to register after the ninth question. (This question does not make admission results, candidates can do their best to do it).

Zhang Xingxing: "......"

The teacher is really good at playing, and if you don't do admission results, why are you doing it...... He is China's most internationally renowned writer, and he is known as China's Charles Dickens.

The tenth question is also scratched, (this question does not make admission results, candidates can do their best to do their best), grandma is a bear, Zhang Xingxing has a false alarm, but at this time the end of the exam is also time.

After the invigilator finished collecting the test papers, the examination room was full of exclamations.

"I'm finished!"

"The math was so hard that I had several problems that I couldn't solve. ”

"Me too. ”

"Why is math so difficult, and there are so many questions?"

"Comrade Zhang Xingxing, how did you do in the exam?" Zhou Kaixin always couldn't help but ask others how they did after the exam.

"It's okay. ”

Looking at the entire examination room, only Zhang Xingxing was very calm, not stimulated by the difficult problems of mathematics at all.

He sighed.

"Comrade Zhang Gaoxing, you are really calm, I was just about to do the last two questions, I don't have time, alas, I can't do math at all. ”

"The last two questions are non-exam questions and will not be counted in the admission score. ”

"What?"

"When you're hungry, eat...... In the afternoon, take the last class, and open new students every week. ”

The last geography exam in the afternoon, after taking it, the curtain of the college entrance examination that caused a sensation in the entire land of China in 1977 is coming to an end.
