"Let the function. if it is an odd function, then the tangent equation of the curve at the point is: A.; B．； C．； D．...... This question is a tangent equation of an odd function, which is relatively simple...... Because f(x) is an odd function, so f(—l)=—f(1), that is—l+a—l—a=—(1+(a—l)+a) solves a=l, so f(x)=x, squared + x, so f(x)=3x squared+l, f(0)=l, so the tangent equation is y=x, choose D".

"The motion of a high-speed train in the starting stage can be regarded as a linear motion of the average acceleration with zero initial velocity, and the kinetic energy of the train in the starting stage is proportional to the time it has elapsed, B. proportional to its displacement, C. proportional to its velocity, and D. proportional to its momentum...... This question tests the concept of kinetic energy, and the following

statements are false: A. Sucrose, fructose and maltose are all disaccharides, B. enzymes are a class of proteins with high selective catalytic properties, C. vegetable oils contain unsaturated fatty acid esters, which can fade Br₂/CCl4, D. The final products of starch and cellulose hydrolysis are glucose...... This question tests some basic knowledge, choose A"

......

"Is it difficult? "Qin Hongyu has been going all the way.

Although Xia Tiantian's questions are not difficult, they are all based on the knowledge points in the notebook, which is simply easy for him.

In addition to the three difficult compound questions that require divergent thinking and are mixed with a variety of knowledge points, which burned a lot of his brain cells, he almost all of the remaining 27 questions can probably know what knowledge points are tested and what the possible answers are ......when he looks at the question stem

"Mom doesn't have to worry about my study anymore, so easy~

" After choosing the most likely answer to the last question that couldn't be done, Qin Hongyu pushed the information book to Xia Tiantian, "Teacher Xia, you can read the papers." "

So fast?" Xia Tiantian was shocked again.

It's only been less than fifteen minutes, and I've finished such a difficult 30-question

question? My own speed is just like that, right?

On the other side, the fat man, Xiao Shuai, Eryu, and Little Wolf, who were originally in full swing to find the answer, were at a loss.

The four of them worked together, divided labor and cooperated, but before they could find out the answer, Qin Hongyu actually handed in the paper?

"How can you play this?" Xiao Shuai finished speaking in the group, and posted a "I'm also desperate" emoji.

"Brother Qin is really reckless. The little wolf sighed.

Eryu wanted to say that he had already thought that Qin Hongyu would be cool, but seeing that the fat man's eyes were not good, he still held back and didn't dare to say it.

Qin Hongyu had a calm face, "You have strength, you are so willful."

Xia Tiantian originally wanted to persuade him to check again, but seeing him look like such a stinky fart, he was a little angry and started to review it directly.

While reviewing, she was still worried, "This guy is so unorthodox, when the results come out later, he will definitely not meet my standards, do you really ignore him until the end of the college entrance examination?"

As soon as she thought of this, Xia Tiantian secretly glanced at Qin Hongyu again.

When she found that Qin Hongyu's face was full of confidence, she couldn't help but scold: "Big pig's trotters, no heart and no lungs!" Qin Hongyu

was shot inexplicably and looked at her in confusion.

Xia Tiantian snorted, and began to review the test questions again.

But as more and more test questions were reviewed, the original sorrow on her face gradually faded, and was replaced by restrained surprise.

And when she finished reviewing all the questions, she couldn't help suppressing her emotions, raised her head sharply, and looked at Qin Hongyu.

When Eryu and the others saw this posture, they thought that Xia Tiantian was angry, and they all lowered their heads and couldn't bear to look at the next tragedy, but brushed wildly in Qin Hongyu's red envelope group: "It's cold

, the storm is coming!" "Silent mourning

for Brother Qin!" "I feel sorry for Brother Qin for three minutes

!" "Brother Qin doesn't cry, stand up and masturbate; after the college entrance examination, he is a good man again!"

......

But just when they were choked, Xia Tiantian spoke: "The correct rate is 90%, 135 points! Among the three wrong questions, except for one moderately difficult question, because you carelessly read the wrong decimal point, the remaining two are English! Even in the mathematics and physics subjects, you have answered the three most difficult compound questions correctly." You honestly confess, did you secretly tutor?

" As soon as she said this, the little wolf in Qin Hongyu's red envelope group couldn't help but burst into foul language: "I'm going to make a big mistake! Did I hear it wrong, Xia Xiaohua said 135 points?"

"Your uncle will always be your uncle, Brother Qin's cowhide

!" "Hand ice Coke to the big guy!" "

@二鱼, you dog-headed fortune teller, stand up and be beaten!"

......

Qin Hongyu smiled: "I just disdained to study before and wanted to hide my strength, but in fact, I am a genius." "

Believe you ghost!" Xia Tiantian had a surprise in her eyes that couldn't be concealed, "You must have reviewed my notes a long time ago, right?" "

Villain!" Xia Tiantian's shy and angry villain made Qin Hongyu's bones crisp.

"Why am I a bad guy?" Qin Hongyu wanted to explain, but Xia Tiantian had already happily snatched his teaching materials, "If you are willing to gamble and lose, I will draw you the rest of the key test points." As

she spoke, she carefully opened Qin Hongyu's textbook and sketched it bit by bit. When it comes to some content that is very likely to be in the college entrance examination, she will also write a sentence or two of annotations and her own opinions with a pen.

Qin Hongyu looked at her silently from the side.

Before, he had only heard that serious men were very handsome, but after seeing Xia Tiantian's serious sketch, he realized that serious girls are also beautiful. Especially like Xia Tiantian, who is already good-looking, once she gets serious, she really feels unbelievably beautiful.

"How can you be so good-looking?" he blurted out.

Xia Tiantian's originally smoothly sketched pen tip suddenly shook, and there was an extra fluctuation on the originally straight line.

After that, her originally calm eyes suddenly waved, as if a stone had fallen into the calm lake.

After a while, she calmed down a little, and couldn't help but secretly glance at Qin Hongyu from the corner of her eye.

After finding that he was staring at herself, she was ashamed and happy, and couldn't help but slap Qin Hongyu, and said, "What have you been looking at me for, do I have college entrance examination questions on my face?"

"Why didn't you find out before, you still have a flamboyant tongue?" Xia Tiantian looked at Qin Hongyu as if she had discovered a new continent, but her heart blossomed.

Qin Hongyu took a textbook that had already been drawn, and said with deep meaning, "There are many more that you haven't discovered."

"Keep your eyes open.

Every moment from now on will be a time to witness miracles.

Xia Tiantian couldn't get used to his stinky appearance, and was about to strike a few sentences, but Qin Hongyu had already raised his hand in advance and stopped: "This is the end of the chat, I'm going to study." "

I love to learn, and learning makes me happy

!" Xia Tiantian suddenly became angry, and muttered: "I don't recognize people when I turn my face, men are really big pigs' trotters!"

However, although she said so, she still didn't bother Qin Hongyu, and silently helped him draw the rest of the key points, and then stacked those teaching materials neatly and stacked them on Qin Hongyu's desk.

After doing all this, Xia Tiantian glanced at Qin Hongyu, and when she saw that he was really engrossed in the review, she smiled with relief, and then continued to busy with her own affairs.
