Start with a Blind Date

Originally, Officer Liu thought Liu Ting was a little capable, but that was all he expected?

After reading Liu Ting's first question, Kuo Gu suddenly lost interest in reading it any more.

Now half an hour has passed for the exam, but Liu Ting only did 5 multiple-choice questions.

Assuming that Liu Ting can do all these questions, he can only do 20 multiple-choice questions at most.

Anyway, the entire examination room ran out of exams, so let these people score 20 points.

It's not a big deal either.

As soon as he thought of this, Kuo Gu shook his head and left the examination room.

Officer Liu went to other examination rooms to patrol the exam.

Another examiner in the examination room saw the people from the Education Department leave, and he simply began to collect his examination papers.

Now only Qin Chen, Liu Ting and a few candidates are left in the examination room.

Except for these classmates, the examiner collected all the other examination papers.

Then, the examiner took out his mobile phone and started playing the game.

Playing around, he suddenly answered the phone.

Then, the examiner lowered his voice and became ambiguous with the person at the other end of the sentence.

Gao Lan saw at a glance that the examiner seemed to be engaged in the subject.

Sure enough, after the examiner answered the phone, he seemed a little restless.

Upon seeing this, Gao Lan said, "This teacher can leave first if there is something to do. I am here."

Hearing Gao Lan's words, the male teacher thanked him and left the examination room.

Gao Lan took the blank test papers from the male teacher's seat and put them in order.

She rolled the test paper with both hands and began to pace in the examination room.

However, Gao Lan walked around in circles around Qin Chen.

Qin Chen was stunned by Gao Lan, "Teacher, can you not turn around me, I'm going to throw up!"

Seeing what Qin Chen said, the stack of test papers in Gao Lan's hand was shot directly on Qin Chen's desk.

"Stop talking nonsense, keep writing!" Gao Lan.

Gao Lan threw the blank test paper to the blank area of ​​Qin Chen's desk, and then sat behind the examination room.

Seeing Gao Lan leave, Qin Chen let out a sigh of relief this time.

Then, he repeated the old tricks.

Holding a pen in both hands, bowing left and right, and writing two test papers at the same time.

In a short while, Qin Chen finished both of the two joint examination papers.

There is still more than an hour before the exam is over.

This time the joint examination was considered to be the joint examination of the whole city, so the examination room was very strict, and the examination papers were not allowed to be handed in in advance.

Anyone who has to hand in papers in advance will be treated as abandoning the exam.

Qin Chen used to finish the test paper as if lying in the dormitory, but the next moment he thought of the painful rules.

Want to sleep, now I don’t feel tired.

But now there is more than an hour before the exam, Qin Chen really doesn't know what to do.

Suddenly, Qin Chen found that there was a stack of blank test papers on the table.

This is what Gao Lan put here just now.

These test papers belong to the candidates in this examination room.

But just now because of being so troubled by the Jinling Chinese teacher, these exams were abandoned.

Qin Chen looked at these blank test papers and couldn't help but reach out and take them.

Being idle is also idle, Qin Chen took these test papers and started to do them one by one.

At the beginning, Qin Chen only made the previous choices and filled in the blanks.

But later I found it was too simple and not challenging at all.

So Qin Chen began to do the following big topic.

This is addictive and can't stop.

Qin Chen didn't simply copy the answers he had made.

He uses different ideas for solving problems for every test paper to pass the time.

At this time Gao Lan was sitting behind the examination room doing nothing.

Suddenly looking up, Gao Lan found that Qin Chen was actually doing other people's test papers.

Gao Lan hurried to Qin Chen, wanting to see what was going on.

Walking to Qin Chen, Gao Lan found that the two joint examination papers belonging to Qin Chen had been completed by him at this time.

The blank test papers of the students who had previously abandoned the exam were also made by Qin Chen.

As Qin Chen's head teacher, Gao Lan's first reaction was that Qin Chen was doing it randomly.

Gao Lan also knew Qin Chen's mathematics scores.

Often a one-hundred-point test paper can get one or two points.

Moreover, this is the score obtained from the multiple-choice exam.

As Qin Chen's head teacher, she naturally did not allow Qin Chen to be such a fool.

But in the next moment, when Gao Lan saw Qin Chen's problem-solving process, she couldn't help but breathe in a cold breath.

Although Gao Lan is a graduate student in the Chinese Department, she can probably tell right from wrong to the second-year mathematics topic.

This time the mathematics entrance exam, the first mathematics problem is like this.

"An express train is 140 meters long and travels 22 meters per second. The local train is 125 meters long and travels 17 meters per second. How many seconds does it take for the express train to catch up to the local train from behind to overtake the local train?"

After reading this topic, Gao Lan couldn't help but fall into contemplation.

After a long while, Gao Lan realized that this was a train overtaking problem.

She has studied this kind of subject in graduate school.

If you follow the normal thinking of solving problems, then you need to apply formulas.

The time it takes for the express train to catch up to overtake the slow train = the length of the two trains and/the speed difference between the two trains.

According to the conditions given in this question, the formula listed should be 140+125)/(22-17)=53 seconds."

Looking at the answer given by Qin Chen, it was indeed 53 seconds.

Gao Lan didn't expect Qin Chen to be able to do this kind of problem.

Although this question is placed in the first question of the mathematics entrance examination, it is relatively simple.

However, the comparison is a point of knowledge that can only be mastered at the graduate level, Gao Lan could not have imagined that Qin Chen could actually master it at the undergraduate level.

But this is not the end, Qin Chen not only used this method to solve the problem.

He also used many other different methods.

For example, first subtract the slow speed from the fast speed, and then divide it directly by the speed difference.

Or, multiply the ratio of the speed difference by the ratio of the speed difference.

The answers to these problem-solving ideas are all 53 seconds.

This is an eye-opener for Gao Lan.

She never expected that in addition to applying formulas, she could write so many ways to solve the problem of train overtaking.

This is not over yet, Gao Lan looked at the second big question curiously.

"A highway~www.readwn.com~ Team A needs 24 days to complete the repair alone, and team B needs 30 days to complete the repair separately. After a few days of cooperation between A and B, team B stops and rests, and team A continues to repair it for 6 days to complete."

"How many days did Team B repair?"

After reading this math problem, Gao Lan's brain buzzed.

This obviously goes beyond the mathematics knowledge at the undergraduate and even graduate level.

Thinking of such a difficult topic, let alone graduate students can't do it.

I'm afraid that even the average doctoral student can't do it.

She knew it was difficult for the Education Department to issue questions, but she didn't expect it to be so difficult.

In the morning’s Chinese test, I used a piece of "University" that was just unearthed.

Unexpectedly, in the afternoon mathematics exam, the Jinling Education Department had such a serious problem beyond the outline.

At this moment, Gao Lan felt the deep malice of the questioning team.

Seeing Qin Chen wrote the answer, Gao Lan looked at it curiously.
