Reborn Xueba, you don't really think that studying is difficult, do you?

Needless to say.

The fifth interviewee must be Lin Bei.

From the moment he walked into the interview room, he was directly ignored by Wang Dahui, the manager of the Skyworld Education and Training Institute, but he didn't care at all.

Instead, he focused all his attention on the six test questions in front of him, and started working on them immediately.

The first is language.

Since it is a simple test, there are no multiple choice questions.

And directly it is a modern text reading, a classical Chinese reading and a poetry appreciation.

And they all focus on answers, which are very difficult.

In particular, the time is only 10 minutes, and the average answer for a big question is only 10 minutes, which is more difficult.

But Lin Bei didn't think about it, just went "da da da da da" non-stop, and wiped it out.

It took... about 10 minutes?

That's right, it's 10 minutes, and the Chinese test questions are finished.

That speed is unbelievably fast.

Even if the golden bachelor of hundreds of millions of years is here, I'm afraid he will have to bow down.

I saw that the four interviewees next to me seemed to have not even finished the first modern Chinese reading!

It's worth mentioning.

The test questions for each subject this time were carefully selected by Wang Dahammer, and the difficulty reached A+ level.

Picking out one at random is far more than the college entrance examination questions, and it is generally impossible to finish it quickly and well.

Even with the strength of Lin Beixueshen, it is impossible to solve the Chinese test questions in 10 minutes.

But, he can still cheat!

Such a good job costs 1000 yuan an hour, and 14000 yuan in seven days.

Although he doesn't love money that much, but for himself and Zhao Qinghan's meal tickets for the next few months.

He really worked hard this time.

The magic halo 1.0plus is turned on, the super magic skill is activated, and the superposition of the two makes his thinking run to the extreme quickly, and the efficiency of solving problems can be increased by five or six times.

without any exaggeration.

At this moment, it is limited by his hand speed, otherwise it would not even take 10 minutes to do the Chinese test questions.

After all, although these Chinese test questions are difficult, they are not out of the scope of the college entrance examination and are within his acceptable range.

Then, there is mathematics.

There are also no multiple choice questions and no fill-in-the-blank questions.

There are only three answer questions.

After all, multiple-choice questions involve luck and blindness, and you can even use the method of elimination to take shortcuts, and filling in the blanks is generally not too difficult, and only answering the questions can test the synthesis.

only see...

"First question: The opposite sides of the interior angles A, B, and C of △ABC are a, b, and c respectively. Let (sinB-sinC)^2=sin^2A-sinBsinC."

"(1) seek A;"

"(2) If √2a+b=2c, find sinC."

This question can only be said to be general.

It can barely reach the level of answering questions in the college entrance examination, but it is not the finale, and the difficulty of the first and second questions is overwhelmed.

In fact, the difficulty of this question itself is not high. The real test point lies in whether the logical thinking of the answerer is strong enough and whether he can answer it in the shortest time.

A maximum of 10 minutes. If the question is not completed within 10 minutes and a full score is obtained, the test is over.

But Lin Bei, it only took 2 minutes.

It can be said that without thinking, he directly wrote the most perfect process and answer.

only see...

“（1）：由已知得sin　^2B　+　sin^2C　-　sin^2A　=　sin　BsinC　，故由正弦定理得b^2＋c^2　-a^2=　bc。”

“由余弦定理得　cos　A　=（b^2＋c^2　-a^2）/2bc=1/2。”

"Since 0° < A < 180°, A = 60°."

“(2）：由（1）知　B　=120度-　C　，由题设及正弦定理得　√2sin　A　+　sin　(120°-　c　)=2sinC。”

“即√6/2+√3/2cosC+1/2sinC=2sinC，可得cos　(　C　+60°)=-√2/2。”

“由于0°<　C　<120°，所以　sin　(　C　+60°)=√2/2，故　sinC　=　sin　(　C　+60°-60°)=　sin　(　C　+60°）oos　60°-　cos　(　C　+60°)　sin　60°=（√6+√2）/2。”

Ok.

In 2 minutes, solve the first problem mathematically.

Then there is the second question.

"It is known that the function f ( x ) = sinx - In (1+ x ), f '( x ) is the derivative of f ( x ), prove that..."

"(1) f (x) has a unique maximum point in the interval (-1, π/2);"

"(2) f(x) has one and only two zeros."

This question looks ok.

After all, function derivation is always more difficult than the trigonometric function above, but that's all.

This problem-solving process is a bit complicated, and if you don’t have 10 lines, you will definitely not be able to do it. It takes 3 minutes for a normal person to get started, but it only takes [-] minutes for Lin Bei to get it done.

Go straight to the third question.

"Definition: Let A be a square matrix with second-order integer coefficients. If there is a square matrix B with second-order integer coefficients such that AB =BA=I=[1,0][0,1], then A is said to be invertible."

"(1) A is a square matrix with second-order integer coefficients. Proof: The necessary and sufficient condition for A to be invertible is the determinant A=±1 of A.

“（2)设A,　B　均为二阶整系数方阵，且　A　,　A　+　B　,　A　+2B,　A　+3B,　A　+4B均可逆，试证：A　+5B亦可逆。”

This question is really interesting.

Although the knowledge point of the question is still high school, the test center has gone beyond the scope of the college entrance examination.

It belongs to the kind where the sword is slanted and deliberately embarrassing.

Ordinary high school students really can't do it.

Even Lin Bei was a little dazed at first glance, after all, he had never been exposed to this kind of question.

For this reason, he spent a full 2 ​​minutes reading the questions, but after spending another 3 minutes, he came up with the answer.

After all, although this question is a bit biased, it is really difficult, not even as good as the second question.

As long as you understand the question and have some understanding of the pigeonhole principle, it doesn't take much effort to solve the question.

As for the pigeonhole principle, one can learn it as early as the sixth grade, so normal people must know it!
2+3+2+3=10。

As for the three math questions, Lin Bei took only 10 minutes to solve them, just like the Chinese test questions.

Immediately afterwards, there are four subjects of foreign matter, metaplasia and biochemistry.

Difficulty is about the same as that of Chinese and mathematics.

Most high school students would hand in their guns immediately when they saw this, but Lin Bei became more and more excited, and the more he did it, the happier he was.

At 10:30, foreign language graduates.

At 10:40, physics graduates.

At 10:50, chemistry graduate.

At 11 o'clock, the last creature died.

With the help of learning magic halo 1.0plus and super magic skills, it took three hours to solve the six subjects, but Lin Bei took only one hour to finish all of them. Not to mention, he licked his lips instead, with a look of unsatisfactory expression on his face.

"These questions are very interesting! They are much more exciting than the usual ones, but there are too few questions."

"It's like an old scalper plowing the land. The old scalper has just exerted his strength, but the cultivated land is gone. The rest of his body has nowhere to use his strength. He can't get up or down. I feel panicked!"

"( д)<Too much!!!"
