The cloze of the English test paper is a relatively difficult type of question, and the four answers of ABCD are also easily confused words.

There are several directions such as word meaning, grammatical structure, semantic content, etc., so it is often the focus of losing points.

Even a student like Dong Zijin, every time he does cloze, he must be highly concentrated and earnestly distinguish the difference between different answers.

On average, she finishes one cloze, and it takes three or four minutes to complete, and ten articles take at least half an hour.

but……

It only took He Xuan less than five minutes to make ten articles just now. It was exactly the kind of filling out the answers at a glance and ten lines. How could this be called serious work?

however……

When Dong Zijin compared He Xuan with his own answers, he was shocked.

"CCBAD..."

"ACBDD...CBBAD..."

"God! He Xuan's answer is the same as mine? It's just... just two Kong's answers are different, this... how is this possible? Is he really answering the question seriously? But, in such a short time, It is absolutely impossible to finish."

Frozen on the spot, Dong Zijin's whole mind was in chaos.

Because she really couldn't think of other possibilities besides He Xuan's serious work.

If He Xuan had memorized the answer beforehand, then why should he act like this?Besides, this one cloze fills in fifteen blanks and ten is one hundred and fifty answers. It is even more difficult to memorize.

Unbelievable Dong Zijin, looked back at He Xuan, and saw that he was just as usual, joking with Zhang Haoran hippiely.

"He Xuan, what the hell is going on? What kind of person are you... on earth?"

Getting a little confused, Dong Zijin felt that he couldn't see He Xuan even more.

However, just because of what happened between classes just now, there are a few boys who have been pursuing Dong Zijin, wanting to fight for Dong Zijin, and by the way express themselves well.

"He Xuan, do you think you are great in the class? Even the squad leader dare to tease?"

It was Deputy Squad Leader Lu Xiqing who was usually the most cunning person in the class. He immediately stood up when he saw an opportunity to perform, and taught He Xuan very proudly.

"Fuck! Lu Xiqing, what are you so blind to? The squad leader didn't say anything, wanting you to support it? Don't look at... what you are."

It was too late, He Xuan himself hadn't reacted yet, and Zhang Haoran, who was at the same table, had already crossed the body of two hundred jin and glared at Lu Xiqing fiercely.

"Zhang...Zhang Haoran, what's the matter with you? I'm talking about He Xuan."

Lu Xiqing flinched back slightly. He was less than one meter and seven meters tall, and he did appear to be a little weak under He Xuan and Zhang Haoran's 1.8 meters.

"Xuanzi is my brother. You say he means me. Anyway, if you have the courage to try another beep, I see if you can walk straight out of the school gate after school?"

Don't look at Zhang Haoran in the corners of the last row on weekdays, with no sense of presence at all, but when he stood up and howled, it was impossible for anyone in the entire classroom to ignore him.

"You... you are good."

When Zhang Haoran yelled at him like this, Lu Xiqing immediately persuaded him and returned to his seat in fright.He remembers clearly. Once in the second year of high school, He Xuan didn't know who provoked someone outside the school. Several gangsters chased He Xuan to fight. As a result, Zhang Haoran appeared and threw several gangsters out.

Lu Xiqing didn't want to hit the monster Zhang Haoran hard, but he was also aggrieved in his heart, and finally found an opportunity to perform in front of Dong Zijin. How could he just miss it?Must find a way to rectify He Xian severely.

"Xuanzi, have you seen it? Some people are bullying and afraid of hardship. Just like a dog, if you make a fierce cry, he won't dare to bark."

Zhang Haoran laughed deliberately and said loudly, his friendship with He Xuan was not comparable to that of ordinary people at the same table.

"Indeed, some people are dogs and mice."

He Xuan has become accustomed to Lu Xiqing's finding faults. Since Teacher Qin asked Dong Zijin to "help" herself, some so-called "flower-protecting messengers" rushed to perform.

However, He Xuan also regarded them as buzzing flies and ignored them.

After sitting down again, He Xuan took out the book again and flipped through it quickly.

"Xuanzi, do you really plan to send a'shit' figure to be strong? Just your grades, there is still a rescue? You still read the math puzzle book? Do you understand?"

The very boring Zhang Haoran looked at him and yawned.

"Of course. Not only me, Hiroko, you can also, trust me... We will all get good grades in the test. These maths, physics, chemistry and English problems will all be solved..."

After such fast learning, He Xuan found that the effect was very good. The cloze answer just now proved that the props on his body... are very helpful for learning.

Therefore, He Xuan had a bold idea in his heart.

When I was almost done learning, I secretly lent these props to Haozi, so that he could counterattack at the end of the college entrance examination.

It's just that He Xuan can't make it so obvious now, and can only encourage Haozi to keep him from losing confidence.

However, Zhang Haoran had already had a smashing attitude. He even had a high price to buy qualifications for the first high school. He had been in a mess since junior high school, and he had no hope of learning.

However, Zhang Haoran didn't take He Xuan's words seriously, but the students around him heard it, but thought it was the funniest joke they heard today.

The two crane-tailed students in the class said that they can get good results in the college entrance examination?

Dute has less than 30 days left, and still think he can counterattack?What kind of mysterious confidence is this?

"Xi Qing, I laughed so hard. Did you hear what He Xuan just said? He still wants to counterattack? Is he really the protagonist in the novel?" Lu Xiqing's deskmate Yang Weicheng smiled. Said.

"Foolish people talk about dreams. Anyway, bragging and don't pay taxes. He really thought that if Teacher Qin arranged Dong Zijin to help him, his grades would skyrocket?"

Lu Xiqing said sourly, at the same time, there was some bad water in his heart.

The class bell rang, and this is a math class.

The mathematics teacher Lian Hengxin is an old scholastic. He was bald in his forties and wore gold-framed eyes. He was very old-fashioned when he talked about questions. Everything was just scores and standard answers.

In the same way, even the teacher's temper is the most grumpy among all the subject teachers, and he even punishes students with a pointer.

It can be said that even if it is a top student in the eyes of teachers like Dong Zijin, it is inevitable to be afraid when facing even teachers.

And the mathematics class is also the only place where He Xuan and Zhang Haoran dare not go to sleep in class, even pretending to be listening carefully.

"Class!"

He took the lesson plan and put it on the podium with a bang. Even the teacher's voice was a little hoarse, and it seemed that he was in a bad mood today.

At this moment, the whole class's hearts almost seemed to hang up. Everyone was excited about 120,000 points, fearing that even the teacher would lose their temper by accident.

"Today, let's talk about some typical problems. In a moment, these questions...I hope that some students will take the initiative to do it on the blackboard..."

When he opened his mouth, he went straight to the subject, and even the teacher scribbled a big math problem on the blackboard, and then asked: "This problem is about conic section. Who will do it?"

After the teacher even spoke, the class was silent.

This question is actually not difficult, but because it's even the teacher's class, if you accidentally make a mistake... then you will be punished and scolded, no one wants to be such a bird.

Even if he did it right and did it a little slower, the problem-solving steps and ideas were not the same as his standard answer, and he would still be said a few words harshly.

"I'm coming! Even the teacher..."

After waiting for more than ten seconds, no one raised his hand. As the class leader, Dong Zijin had to volunteer, and then went to the podium to solve this problem perfectly.

"Have you seen these steps? Dong Zijin's writing is very beautiful. The formulas are listed and the numbers are inserted...the answer is here, it is simple, isn't it? So don't be afraid when you see this type of topic , And don’t scare yourself. Carefully analyze which type of question this is, find the formula to apply, and analyze the known conditions..."

Comparing with Dong Zijin's answer, even the teacher explained it satisfactorily for a few minutes, which is an analogy for this type of question.

Then he erased the question again and continued to write another question on the blackboard.

Known function f(x)=x-1/x-alnx

(1) If f(x) has no extreme point, find the value range of a;

(2) Set g(x)=x+1/x-(lnx)2, when a takes the maximum value in (1), find the minimum value of g(x);

(3) Prove the inequality: ∑1/√(2i(2i+1))>ln(2 to the n+1 power)/(2 to the n power+1) (n∈N*).[Note: The mathematical symbols cannot be typed here, and the problem cannot be completely solved, so let's do it!

Huh!

As soon as this question was written, the whole class took a breath.

It can be said that in high school mathematics, this type of function is the most difficult type to find the extreme value and the maximum value and the minimum value, and to prove the inequality.

Some students who are not good at mathematics start to feel pain every time they see a long list of inequalities in the summation formula of ∑.

"Who will do this question?"

After finishing the question, Teacher Lian glanced down. None of the students in the class dared to look at each other with Teacher Lian!

Everyone hurriedly lowered their heads. Who dared to confirm their eyes with Teacher Lian at this time?

"How? No one dares to come up and do it? This question...not difficult!"

No one took the initiative, even the teacher's face sank.

But as soon as he finished speaking, Dong Zijin raised his hand again: "Lian teacher, let me come!"

No way, Dong Zijin really didn't want to go up every time, but as the class leader, in order not to embarrass the teacher and not to embarrass the classmates, she often had to go up on her own.

"Dong Zijin, you sit down. You come up every time. What about the other classmates? Is it all air sitting here?"

As soon as I saw that Dong Zijin volunteered again, even the teacher pointed at everyone furiously and cursed, "You...you are really the worst class I have ever taught. Even the courage to come on stage to do the topic No more?"

At this moment, the deputy monitor Lu Xiqing felt it was a good opportunity, so he suddenly raised his hand and stood up and said, "Teacher, let He Xuan go up and do it? When class was over, I heard He Xuan holding the math puzzle book. I confidently said that these problems are nothing at all! I think he will definitely do this question..."
