Start with a Blind Date

Director Liu thought that Liu Ting was capable, but this is it?

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

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

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

Anyway, all the exams in the entire exam room were exhausted, and these people were asked to score 20 points.

No big deal either.

With this in mind, Officer Liu shook his head and left the examination room.

Officer Liu went to other examination rooms for inspections.

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

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

Except for these students, the examiner put away all the other exam papers.

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

While playing, he suddenly picked up the phone.

Then, the examiner lowered his voice, flirting with the person on the other end of the conversation.

Gao Lan could tell at a glance that the examiner seemed to be looking for a partner.

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

Seeing this, Gao Lan said, "This teacher can leave first if you have something to do. I'm here."

Hearing what Gao Lan said, the male teacher thanked him and left the examination room.

Gao Lan took the blank test papers from the male teacher's seat and stacked them neatly.

She rolled up the test paper with both hands and started pacing in the examination room.

But Gao Lan walked around, circling around Qin Chen.

Qin Chen was stunned by Gao Lan, "Teacher, can you stop surrounding me, I'm going to throw up!"

Seeing what Qin Chen said, Gao Lan slapped the stack of test papers on Qin Chen's desk.

"Stop talking nonsense and keep writing!" Gao Lan said.

Gao Lan threw the blank test paper to the empty space on Qin Chen's desk,

Then I sat at the back of the examination room.

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

Then, he did it again.

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

After a while, Qin Chen finished the two joint exam papers.

There is still more than an hour before the end of the exam.

This time the joint exam was considered to be the city's joint exam, so the exam room was very strict, and the exam was not allowed to be handed in in advance.

Anyone who submits the papers in advance will be treated as an abstention.

Qin Chen felt like going back to the dormitory to lie down after finishing the test paper, but the next moment he thought of this painful rule.

I want to sleep, I don't feel tired now.

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

Suddenly, Qin Chen found a stack of blank test papers stacked above the table.

This is what Gao Lan put here just now.

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

However, because of the trouble caused by the Jinling Chinese teacher just now, these exams were all abandoned.

Looking at the blank test papers, Qin Chen couldn't help reaching out and taking them.

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

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

But it turned out to be too easy and not challenging at all.

So Qin Chen started to work on the next big question.

It became addictive and I couldn't stop doing it.

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

For each test paper, he adopts different ways of solving problems to pass the time.

At this time, Gao Lan was sitting at the back of the examination room doing nothing.

Suddenly looking up, Gao Lan found that Qin Chen was actually doing someone else's test paper.

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

Walking up to Qin Chen, Gao Lan found that Qin Chen's two joint exam papers had already been completed by him.

And the blank test papers of the students who gave up the test before were also messed up by Qin Chen.

As Qin Chen's head teacher, Gao Lan's first reaction was that Qin Chen was messing around.

Gao Lan also knew Qin Chen's previous math scores.

Often a test paper with a score of 100 can get 10 or 20 points.

Moreover, this is the score obtained from the multiple choice questions.

As Qin Chen's head teacher, she naturally didn't allow Qin Chen to mess around like this.

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

Although Gao Lan is a graduate student in the Chinese Department, she can probably tell right from wrong when it comes to math questions in her sophomore year.

The first major math question in this mathematics entrance exam is like this.

"A fast train is 140 meters long and travels 22 meters per second, and a slow train is 125 meters long and travels 17 meters per second. How many seconds does it take for the fast train to overtake the slow train from behind?"

After reading this question, Gao Lan couldn't help but fell into deep thought.

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

She has studied this kind of topic in graduate school.

If you follow the normal problem-solving thinking, you need to apply formulas.

The time taken by the express train to overtake the slow train = the length of the two train bodies 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 Qin Chen's answer, it was indeed 53 seconds.

Gao Lan didn't expect that Qin Chen could do this kind of problem.

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

But it is a knowledge point that can only be mastered at the postgraduate level. Gao Lan did not expect that Qin Chen could 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 speed of the slow car from the speed of the fast car, and then directly divide by the speed difference.

Alternatively, take the ratio of speed differences and multiply by the ratio of speed differences.

These problem-solving ideas, the answer is 53 seconds.

This was an eye-opener for Gao Lan.

She never expected that besides applying formulas, she could write so many solutions to the problem of train overtaking.

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

"For a road, it takes 24 days for team A to complete the repair alone, and 30 days for team B to complete the repair alone. After a few days of cooperation between A and B, team B stops to rest, and team A continues to complete the repair in 6 days."

"Ask how many days Team B has been repairing?"

After reading this math problem, Gao Lan's mind was buzzing.

This is obviously beyond the mathematics knowledge at the undergraduate or even graduate level.

Thinking about such a difficult topic, don't say that graduate students can't do it.

I am afraid that even ordinary doctoral students can't do it.

She knew it was difficult for the Education Department to come up with a question this time, but she never thought it would be so difficult.

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

Unexpectedly, in the math test in the afternoon, the Jinling Education Department actually gave such a serious over-the-top question.

At this moment, Gao Lan felt the deep malice of the question group.

Seeing that Qin Chen had written the answer, Gao Lan looked over curiously.
