Although it took a little time to find a house, Qu Guangquan still tried his best to study this week.

The calculation ability is improving, and most of the basic mathematical calculation ideas have been straightened out, especially the key points of this week: binary inequalities (groups) and simple linear programming problems.

On Friday night, Ma Liming entered the classroom with the test papers.

"Students, tonight we tested mathematics, after the last midterm exam, we made very fast progress, judging from the homework, the basic knowledge is okay, but the extended questions are not ideal. In addition, the Olympiad mathematics training should start as soon as possible, and there are students who are willing to participate in the training team, this is the last chance to be selected. ”

Qu Guangquan's heart sank, don't say it, the questions in this exam must be difficult.

"Teacher Ma. Seeing Cheng Gang's eyes, Li Yunlong stood up rubbed, "Since this test is so important, it has to be strict, I am worried that some students will take advantage of the proximity of the seats to make small movements." ”

Although the words were not explained, everyone understood the meaning and pointed directly at Qu Guangquan.

"Well, let's do it, the students in the first, third, fifth, and seventh rows, get out of their seats and take their stools to the corridor outside. Ma Liming ordered.

"Teacher, that Qu Guangquan and Wang Yiming are still together, and they usually copy each other's homework. Cheng Gang looked at the teacher's arrangement, and did not break up Qu Guangquan and Wang Yiming.

"Cheng Gang, you are living the belly of a gentleman with the heart of a villain!" Wang Yiming stood up without showing weakness!

"Wang Yiming, a villain is a villain, ignore him. Qu Guangquan lifted his stool, "Teacher Ma, I'll write on the podium, can you see it?"

"Okay!" Although Ma Liming knew the reason, he wanted to see if Qu Guangquan, who had been agitated, could make progress.

Cheng Gang snorted, sat down, picked up the test paper, and couldn't help but be happy in his heart.

The reason is that this test paper is definitely Mr. Ma's tail: it is extremely difficult, not to mention that Qu Guangquan is a mess of homework all day long, even if he wants to pass the exam.

Especially the last question with 15 points, which is obviously an Olympiad question!

Qu Guang's whole head is a bit big, and this question can be described in three words, that is, "partial, difficult, strange!"

Ordering himself to calm down, Qu Guangquan began to clear the fill-in-the-blank questions.

The basic knowledge is pitifully small, and it takes less than 5 minutes to get started, and almost none of the remaining questions are easy.

The first puzzle is to fill in the tangent equation of the function. According to the high school knowledge in his mind, he almost had no idea where to start, and after judging it, Qu Guangquan remembered that it seemed that it could be solved by using the method of university study.

Taking the draft paper, Qu Guangquan deduced step by step, and the tangent equation finally showed its tail, and Qu Guangquan carefully filled it in.

Everyone else has already started the calculation of the second big question, and Qu Guangquan is still tinkering with filling in the blanks. Ma Liming looked sideways and sighed softly.

An hour passed, and Chen Kun walked into the classroom carrying a bench from the corridor, "Teacher Ma, give you my test papers!"

Qu Guangquan looked at his test paper, and there were several big questions in the back, and he had to score at least 60 points.

Taking a deep breath, Qu Guangquan decided that since time was running out, these questions were all the same difficult for him, so it was better to score according to the score, at least one of them and top a bunch of other topics.

Qu Guangquan flipped over the test paper and came to the last question first, which was worth 15 points.

A high score indicates that there are many steps to think, and if there are two to three bends in general questions, the high score may be twice as much!

However, Qu Guangquan read the last question, which seems to be a difficult problem, but it is an extension problem of binary inequalities (groups) and simple linear programming problems that he has just learned.

Two minutes later, Qu Guangquan took out his pen and deduced it step by step on the test paper, and after a while, it was like planting seedlings and planting trees, and the blank space was neat and tidy, and the derivation steps were written.

Moving his wrist, Qu Guangquan continued to the next question.

After 30 minutes, most of the students in the class were still writing hard, and Mr. Ma clapped his hands: "Stop, stop! No matter how much you write, don't write, no, we will talk about it one by one tomorrow." ”

Cheng Gang gasped, it was difficult for him to get a high score, and he didn't make the last question! The penultimate question only wrote the first step, and he wanted to write it again, but he couldn't help but raise his eyes to look at Qu Guangquan.

This Qu Guangquan is still writing!

"Teacher Ma, some people don't listen to what you say, and they are still writing test papers without stopping writing!"

As soon as Ma Liming heard it, he knew that he was talking about Qu Guangquan.

"Qu Guangquan, you are on the podium, you take the lead, and by the way, put away the test papers of the students in the first row in front of you. ”

If you want to do more questions, Qu Guangquan gritted his teeth and closed his test paper, with an apologetic face: "Everyone, everyone, collect the papers." ”

Cheng Gang's heart moved, and he stood up and began to put away the test papers. Waiting for Qu Guangquan to put the test papers in the first row, including his own test papers, on the lectern, Cheng Gang arrived in an arrow step, and with the help of putting the test papers, he reached out and pulled out Qu Guangquan's test papers.

In the second half of Qu Guangquan's test paper, there are four questions that have not been done, which are blank, the four questions are 5 points, and the four questions are 20 points, and the last few questions Qu Guangquan wrote, but Cheng Gang knew the difficulty, and he couldn't solve it himself, Qu Guangquan couldn't even do such a 5-point question, and the rest was basically in vain.

"Hey, Cheng Gang, I just saw you flip through Qu Guangquan's test paper! What do you mean?" Chen Yao saw Cheng Gang's villainous appearance, and he was a little worried about Qu Guangquan.

"What do you mean? Qu Guangquan bet me that if I fail the exam, I will automatically leave the Osaiban, can I not worry about our Osaiban!" Cheng Gang shook his head.

"The question is too difficult this time, and Qu Guangquan is willing to fail the exam!" "With such a difficult topic, Chen Yao also sweated for Qu Guangquan.

"Then can he swallow back when he speaks, and can he lick back the saliva he spit out!"

"You—despicable!" Chen Yao glared angrily. "If you can't leave the Osban, none of us will say it, but the principal will say it. ”

"It's okay if Qu Guangquan doesn't want to leave Osaiban, lie here and kowtow to me three times, and I won't mention this matter again in the future!" Cheng Gang's voice rang like a bell.

"Qu Guangquan, are you sure to pass the exam?" Wang Yiming became worried, lying on Qu Guangquan's ear and biting his ear.

"Trouble—" Qu Guangquan was really unsure.

Wang Yiming originally wanted to stand up and reason with Cheng Gang, but when he heard this, he died down, pretended not to hear, picked up his book and began to review.

Qu Guangquan was also a little apprehensive at this time, he really didn't expect that Teacher Ma would be so vicious and make such a heart-wrenching test paper, if it was a normal test paper, Qu Guangquan was still very confident that he could pass the test.

There is still class on Saturday, and in the third class in the morning, Ma Liming came to the classroom with the test papers.

"I corrected yesterday's test paper overnight, to be honest, I really admire the students of our Olympiad class, this test paper is in other classes, more than 80 people have ten people who can pass the sky, and only a dozen of our 66 students failed, Chen Kun scored 119 points for such a difficult question, there is only one step to transcrib less, I deliberately deducted one point, otherwise it is a full score!"

More than a dozen classmates failed, and Cheng Gang immediately showed a smile.

Qu Guang's heart sank to the bottom. He was the only one who failed math in the midterm exam.

"I'm starting from the last place now, Li Jiguang 60 points! Wang Yucai 68 points。。。。。。 ”

A full score of 120 points is required to pass with a score of 72.

Teacher Ma read them one by one, and there were ten students, but they hadn't quit Guangquan yet! Cheng Gang was in a hurry.

At this moment, Mr. Ma's high-pitched voice read: "Cheng Gang 71.5 points!"

Cheng Gang never dreamed that he didn't pass the exam! It was all Qu Guangquan's fault, and during the exam, he was always distracted by Qu Guangquan and didn't concentrate!

The moment he took the test paper, Cheng Gang had the heart to die, how could he explain this to his father.

As soon as I sat down, I heard Mr. Ma continue: "Okay, up to now, all of our math failures have been completed!"

What about Qu Guangquan-I obviously see that the four major questions are empty!

Cheng Gang stood up with a sigh: "Teacher Ma, you missed someone, did Qu Guang pass the all-round exam!"

Ma Liming made a downward gesture and asked Cheng Gang to sit down, "This time, I want to praise Qu Guangquan, after May Day, I listened very carefully in class, although the homework has not been too ideal, but as long as there is hard sweat, there will be gains." Qu Guangquan scored 80 points in this exam!"

Qu Guangquan was like being dragged down from a cliff, suddenly sweating all over his body, and took a long breath!

"This 80 points, although it is not high in our class, is definitely a good score in other classes, I propose, cheer for Qu Guangquan's hard work in this section!" Ma Liming took the lead in applauding.

Cheng Gang didn't sit down steadily, and he fell to the ground.

"Cheng Gang, this can be regarded as kneeling for Qu Guangquan!" Wang Yiming laughed!

Ma Liming suddenly remembered Cheng Gang's bet with Qu Guangquan the day before yesterday, and immediately stepped off the podium and found Qu Guangquan, "Forget about your bet on this exam, just know it, just do it!"

Qu Guangquan stood up and leaned into Ma Liming's ear: "Teacher Ma, as long as you agree to Wang Yiming's participation in the training class, this matter will end here." ”

Ma Liming thought for a moment, first shook his head, then nodded again, and finally nodded again.
