I Have a Research Support System

During the summer vacation, it is natural to visit relatives.

Of course, as Xu Qiu got older, such situations became less and less common.

The grandparents of the family had four sons and two daughters. Xu's father was the fifth eldest, that is, Xu Qiu only had one fourth uncle, and the others were uncles and aunts.

As for the grandparents, they gave birth to three daughters and two sons, and Xu's mother was also the fifth and the youngest.

Therefore, Xu Qiu has only one cousin from the fourth uncle's side, and the others are cousins, cousins, cousins, and cousins.

And now, even Xu Qiu has graduated from his senior year. Others, except for his cousin, have already graduated and started working. Some of them didn't even go to university. There is no concept of summer vacation anymore.

On this day, Xu Qiu's fourth uncle brought his cousin Xu Yingying to visit.

In the Xu Qiu family, the names are more casual. There is no such rule that peers must have the same word. The requirements are not high, and the surname "Xu" is fine.

Xu Yingying is 15 years old and has just been admitted to a high school in the provincial capital. Although it is not a key high school, it is still in the middle and upper grades.

The high school entrance examination here is relatively easy, and there is no pressure to enter a higher school. Basically, no matter what the test score is, as long as it is not zero, one or two hundred points are required by high school.

Moreover, even if you don't go to a key high school, you can get in as long as you pay a school selection fee or something.

Of course, don't think about "Rocket Class" or "Hongzhi Class" when it comes to class division. There is a high probability that school-choice students will be grouped together, which may not even be as good as ordinary classes.

If the family has more money, they can spend money in the International Department, plan the route to go abroad, and not participate in the domestic college entrance examination, it is all possible.

However, the province where Xu Qiu lives is, after all, a province with weak college entrance examinations and the lowest educational resources in the country. If you can't get into the "Rocket Class" and "Hongzhi Class" in key middle schools in the province, the ability of the teachers is basically comparable to that. What's up.

Because there are many teachers in the teaching staff who can only preach from the book and dawdle.

But there is no way, the top students who can go out of the college entrance examination rarely choose to come back to build their hometowns, and those who stay are basically not so top-notch people who have been screened once. As for foreign talents, they are even more difficult to attract. It is observed that the population is in a state of loss all the year round.

Even if some teachers are very good, if you ask them to teach those "poor students" who have no intention of learning, it will be difficult to motivate them. Sometimes it is really "a clever woman can't cook without rice".

For various reasons, a vicious circle has formed.

In addition to the level of teachers, there were some cases of corporal punishment of students in the early years.

For example, when Xu Qiu was in junior high school, his mathematics teacher and homeroom teacher, English teacher, and Chinese teacher all knew how to hit people with a board.

The Chinese teacher is a 30-year-old girl, relatively gentle, she doesn't make many shots, and basically only hits "poor students";

The homeroom teacher is quite irritable. Sometimes when his temper comes up, he will directly use the pole of the mop to hit the "poor student"'s thigh. Once he hit more than ten sticks in a row, and the stick broke immediately;

If the first two are mainly aimed at "poor students", the English teacher is uncertain. No matter whether your grades are good or bad, as long as he finds a reason, you will inevitably be beaten. The whole class, including Xu Qiu, has experience. I have experienced the feeling of an English teacher hitting the palm of his hand with plywood.

It is naturally wrong to punish students physically, but there were indeed objective reasons at that time.

Due to a certain incident, many of the parents of this group of students were illiterate and lacked family education for their offspring. As a result, the average quality of this group of students was very poor, and it was difficult to control it with normal education methods.

After class, less than half of the boys would go straight to the toilet to smoke, or play Divine Comedy like "Flying to Other People's Beds" in the class, and plots like "Don't leave after school". I have also seen control knives, switchblades and so on.

If the teacher is not ruthless, it is basically impossible to take the normal classes every day.

For example, in a few "subclasses", the class is full of noise, and a group of people below are ignoring the teacher and chatting.

However, Xu Qiu had never encountered campus bullying in middle school.

On the contrary, he got along well with a few "poor students" in several classes, because they would ask him to copy homework...

Xu Qiu's fourth uncle chatted with Xu's father in the living room, while Xu Yingying bounced to Xu Qiu's bedroom to play with his cousin.

When I was young, Xu Qiu and Xu Yingying played a lot of time, but after growing up and knowing the difference between men and women, they gradually stopped playing so crazy, but overall they are still relatively close.

After seeing Xu Yingying, Xu Qiu ruffled her sister's hair on purpose, and said with a smile, "Yingying, you are getting more and more beautiful. Are there any boys chasing you at school?"

"Huh~" Xu Yingying snorted arrogantly: "Of course there are, but they are all little brats, I don't like them. By the way, brother, I seem to have seen you on Weibo before. What kind of CSI is published by the undergraduates of comprehensive universities..."

"It's SCI. The full English name is Science Citation Index." Xu Qiu scratched his head and explained.

Xu Qiu himself almost forgot about the hot search on Weibo before. The popularity of this kind of thing is limited, and he does not have a strong intention to get out of the circle at this stage. Exposure will soon fade away, so we can't follow the example of celebrities and Internet celebrities to speculate on CP.

Besides, being an Internet celebrity is not as interesting as doing scientific research.

Therefore, he did not notify the family members, including his parents. Except for his cousin, no one else in the family knew about it.

It's normal for the cousin to pay attention to these things.

Nowadays, most post-00s like to follow Weibo, chase stars and so on, especially the current traffic stars, the publicity is overwhelming, young boys and girls who are not deeply involved in the world are easy to be fascinated, and albums are all 10 Buy 10 sheets.

This is very similar to the situation of "the boy eats instant noodles by himself, and then goes to the live broadcast room to reward him as a big brother" and "minors recharge the game with a large amount". It is usually caused by low education or insufficient understanding of the world. of.

In other words, not enough social beatings have been endured.

"That's it." Seeing Xu Qiu acquiesced, Xu Yingying was not too surprised, but just replied casually.

After all, his cousin has always been very powerful in his mind, even if her father often mentions other people's children, it's not surprising that they were trending on Weibo or something.

However, she couldn't understand SCI or something. Although she knew two of the three English words, she didn't know what they meant when they combined. of.

Soon, Xu Yingying bypassed the topic, tugged at Xu Qiu's sleeve and said coquettishly, "Brother, did you bring me a gift when you came back from vacation~"

"Uh..." Originally, Xu Qiu wanted to say "no", because he really didn't prepare a special gift, but seeing his cousin's eager look, he really couldn't say that.

After thinking for a moment, Xu Qiu had an idea: "Of course, I have brought you a set of stationery."

After speaking, Xu Qiu took out a gift box from his backpack, which contained a stationery set of the "Blue and White Porcelain" series, including a ballpoint pen, a notebook, and a metal bookmark, all of which were printed with the school name and LOGO of Shanghai University.

This is a gift given to the graduates by the material system when they graduated. Originally, Xu Qiu planned to keep it as a souvenir, but now he simply gave it to his sister, since he didn't need it anyway.

"Wow, the one with the school name LOGO~" Xu Yingying looked happy, holding the stationery set, and said, "Thank you brother~"

Xu Qiu took the opportunity to encourage her: "Sister, come on, try to get into a good university. I'll wait for you at Shanghai University."

"Yeah," Xu Yingying nodded, "I will definitely work hard."

Xu Qiu breathed a sigh of relief, girls of this age are still easy to fool, basically as long as they receive a gift, they will be happy.

Of course, if you send "Five-Year College Entrance Examination Three-Year Simulation" or "Huanggang Secret Volume", it will probably be...

Xu Yingying paused and said, "By the way, brother, I still have some math questions to ask you."

"Mathematics?" Xu Qiu said confidently, "I'm good at this, show it to me."

Xu Yingying took out some printed paper from her backpack and handed it to Xu Qiu.

There are only three questions on a sheet of paper:

"You are on your way to a distant village. You come to a fork in the road, and there are twin sisters standing there. One of them always tells the truth, and the other always tells the lie. + If you are only allowed to ask one of them A question, how do you ask it to find the right way to the village?"

"It takes one hour to burn an uneven rope from the beginning to the end. Now there are several ropes of the same material. How can I use the method of burning rope to time an hour and fifteen minutes?"

"Assume that there are 100 table tennis balls lined up, and two people take turns to take the ball and put it into the pocket. The person who can get the 100th table tennis ball is the winner. The condition is: each person who takes the ball must take at least one, but at most it cannot exceed 5, ask: If you are the first to get the ball, how many should you get? How can you get the 100th table tennis ball in the future?"

'The questions are not easy, is this really a math problem for middle school students? ’ Xu Qiu frowned, and said doubtfully, "These topics should not be homework for the summer vacation."

"Of course not," Xu Yingying explained: "I will be a freshman next semester, so of course there will be no summer homework during the summer vacation. These are the exercises for the Mathematics Olympiad class that my dad enrolled me in during the holidays."

Xu Qiu was stunned, and said, "No wonder these questions are familiar to me, they are all classic logical questions."

He couldn't help but recall the scene of studying Olympiads in the Children's Palace in middle school. The stormy night, the dilapidated and dilapidated Children's Palace building, and the flickering classroom lights all reminded him of childhood shadows.

However, this level of subject is still simple for him now.

Xu Qiu thought for a while, and then he continued, "Obviously... easy to get... and vice versa..., sister, have you lost your studies?"

Xu Yingying: "???"
