On an ordinary midweek afternoon, as soon as the biology teacher handed out a practice paper, Xu Zhe quickly finished it.

When he got to class, he took out the Olympiad questions assigned by Mr. Lu from the competition group.

But as soon as he wrote a line, a soft girl's voice sounded beside him:

"What's going on here?"

Only then did Xu Zhe notice that Song Xingye, who was at the same table, was looking at his calculus paper.

He said, "You mean this factorization? Oh, this should only be learned next year, you don't have to worry about that. ”

"I know this is something that only the second and third years of junior high school will learn," the delicate apricot eyes blinked twice, "but I also want to learn a little bit earlier, can I?" ”

"Absolutely."

Xu Zhe tore up a blank piece of paper again, and deduced the decomposition formula of the polynomial from scratch.

After the derivation steps are written, it is handed to the girl's table, and it is done.

Seeing that Xu Zhe began to bury his head in the question again, Song Xingye couldn't help asking, "That's good?" ”

"yes, you can read this paragraph, right?"

Song Xingye tried to look at it and found that it was ...... I seem to be able to understand it, and I don't need him to explain it.

For a moment, the girl suddenly envied Tang Lingfei a little. Looking at Feifei, just because her brain is not so smart, she can get Xu Zhe's careful guidance. As for myself, it's over the process of derivation.

Because it is not needed, so there is none?

Just when the girl was silently melancholy, the class bell rang.

The head teacher, Mr. Sun, entered the classroom, and everyone immediately returned to their seats and quieted down. However, Xu Zhe was not disturbed, and was still staring at the Olympiad problem - he had already solved the other questions, and this last one was left. Solving this kind of problem is like spinning around a maze, or like playing a puzzle game, and there is a unique pleasure in immersing yourself in it.

Teacher Sun announced, "Next week our school will hold a sports day. From the first year of junior high school to the third year of high school, all grades will participate. The main events are athletics, long-distance running, sprinting, high jump, long jump, and throwing solid balls...... Students, it's your chance to compete for honor for your class! ”

Students, look at me, I look at you, no one has the intention of taking the initiative to sign up.

Teacher Sun continued, "In this week's PE class, the PE teacher will help us select athletes for the class. Everyone should be enthusiastic when the time comes. If you can get a ranking in the school sports meeting, you will not only win glory for the class, but also add points to your own evaluation! ”

Song Xingye faintly heard that someone was complaining in a low voice.

"How many points does this add?"

"Sounds so tired......"

The girl looked at her table mate.

Xu Zhe finally raised his head at this time, and his eyes were a little bright.

After getting along in the past few months, Song Xingye already understood that when Xu Zhe showed such a gaze, it meant that he was a little interested in something.

So Song Xingye asked quietly, "Do you want to participate?" ”

Xu Zhe: "Why not? ”

Song Xingye: "If you participate, it shouldn't be for that extra point." Because you don't lack it. ”

Xu Zhe: "Yes, I just want to try the effect of exercise. ”

"You still exercise?"

The girl's small mouth opened slightly, and there was a hint of surprise in her apricot eyes.

Xu Zhe: "The frequency is not high, and the amount of exercise is not large, only once every two or three days." After all, I have so little homework to do now, and I still have a lot of time. ”

Unlike Tang Lingfei and Song Xingye, Shen Lan and Xu Zhe spend most of their time together on weekends, and after the end of the Olympiad class in the morning.

This Saturday, after class, Shen Lan came to Xu Zhe again and said, "Do you think it's better for me to start with C or Java?" I read some popular science books that introduced some basic general knowledge and different computer languages. Which language do you think is better? ”

Xu Zhe smiled: "This problem, if you post a post, you can make all kinds of programmers quarrel for three days and three nights." ”

Shen Lan: "Which language is suitable for beginners?" ”

Xu Zhe: "It depends on what you plan to do. Some are suitable for mobile phone software, some are suitable for web pages, and some can be used as glue. Each language has its own advantages and disadvantages. However, if you follow the usual path, you should start in C. ”

Shen Lan: "What if you don't follow the routine?" ”

Xu Zhe: "You can also try to start with Python. The language is not very popular yet, but it will become more and more popular in the future. And the syntax is relatively simple, so it may be quite suitable for getting started. However, there are also arguments that you can't get started in this language, just like you can't learn automatic transmission first when you learn to drive. But seriously, if I want to get a driver's license in the future, I might really choose an automatic transmission, which is simple and easy. ”

Shen Lan was silent for a few seconds and asked, "What language did you start with?" ”

Xu Zhe: "I also started in C. The problem is, you're in your third year of junior high school, and you've already signed up for the math Olympiad. There's a competition coming up next month, and then there's a high school entrance exam next month, are you sure you want to teach yourself programming at this time? ”

Shen Lan sighed: "You're right, I can only study again in the summer." But by that time, it shouldn't have been entirely self-taught. ”

Xu Zhe: "What do you mean?" ”

Shen Lan smiled lightly: "You should also be free during the summer vacation, you can tutor me." ”

Xu Zhe said indifferently: "I originally agreed to tutor you, but I didn't have much time to spare out, and it was originally equal to the time of playing billiards." By the time the summer breaks, I definitely have a lot of things to do. ”

He had already thought about it, and he was going to take his father to register a company during the summer vacation. In the future, whether it is to develop an APP or invest, it will certainly be much more convenient in the name of the company. And in addition to registering the company, he also plans to put some games in the Pingguo App Store to see if he can make a little money.

So when the time comes, whether it is Shen Lan's programming tutoring or Tang Lingfei's tutoring, he can only find time to do it, and it is impossible to spend a lot of time on these little girls.

Shen Lan stared at him.

The girl is in her third year of junior high school, and she will go to high school after the summer vacation. With her grades, it stands to reason that she should go to the top high school in the provincial capital, but this is far away from Xu Zhe. When she can get along again, it can only be two years later - she has no doubt at all that Xu Zhe will definitely be able to go to the same high school.

But there is still too little time to get along.

However, in the blink of an eye, Shen Lan threw away that bit of grievance and seriously considered what to do next......

Xu Zhe suddenly said, "Do you still have any questions?" ”

Shen Lan shook his head slowly: "It's nothing." By the way, I heard that there is a competition for high school students in computer science, do you want to participate in it in the future? ”

Xu Zhe: "I'm only in my first year of junior high school, so I'll talk about it later in high school competitions or something." ”

Shen Lan: "The high school math competition ......"

Xu Zhe: "Don't, I may still sign up for the information competition, but I will definitely not apply for the high school math competition." ”

Shen Lan was a little puzzled: "Why?" You're so smart. ”

But Xu Zhe just smiled and didn't say anything. He knows himself too well, relying on the advantages of the previous life, he may still be able to play the Olympiad at the junior and intermediate levels, and the difficulty at the high school level is enough. What's more, the provincial competition of the junior high school Olympiad does not take too much time and energy, the high school Olympiad is a national nature, and if you don't roll, you really don't need to join in that fun.
