Traveling through 1980 to become a top student

Chapter 10

Everyone agreed to set up a study group to study together.After all, the thirteen girls all had the will to not admit defeat, and they all stood up to participate in the competition against the boys because they believed in Lin Jinglan.

If they were allowed to attend classes and learn solid geometry by themselves, they would not dare to compare with boys, but because of Lin Jinglan and what Lin Jinglan said, they are now very confident.

Lin Jinglan got full marks in mathematics twice in a row, which is a miracle in the eyes of the students. After all, most people are messed up in mathematics now, and most of them can't even pass the exam.

Usually Lin Jinglan helps Zhao Yumei give lectures, and I don't know how many people silently envy her.But Lin Jinglan's busyness was also noticed by everyone, and it involved the bet with Teacher Li that she would get three full marks or be fired. No one dared to delay Lin Jinglan's time rashly, and asked Lin Jinglan to help herself explain.

Now that Lin Jinglan offered to help them teach solid geometry, they naturally wished for it.

The time for the lectures was fixed every morning. Everyone got up an hour early and listened to Lin Jinglan's lecture for an hour before going to self-study in the morning.

Lectures and showing the collection to the whole class are easy to say, but Lin Jinglan has to work hard in private.

Lectures had to be prepared, and as for the collection she had sworn to bring from home for the students to read, how could she have such a thing at home.

There is nothing like this in the world right now!

But the reason why Lin Jinglan dared to make such a promise was because she knew that she could create physical objects through consciousness in the system space, and asked the system if she could take the manufactured things from the system space to the real world.

At that time, Lin Jinglan had just obtained the system, and she was daydreaming, thinking that if she used her consciousness to create a lot of money, would it be possible to bring it to the real world...

Of course, she tried it later, and she couldn't make it with her consciousness, which is extremely delicate and she doesn't understand the manufacturing process.She can only create counterfeit money that is instantly recognizable...

The answer given to her by the system at the time was that she could take the things she created with her consciousness out of the space, but she had to pay a corresponding amount of energy. As for the amount of energy, it was determined by the system.

This kind of energy is not the energy needed by the body, but mental energy. Lin Jinglan doesn't quite understand the systematic explanation, but she just understands that study, work, and thinking all need to consume this kind of mental energy. If she wants to take things out of the system space, she just Use it to pay.

Lin Jinglan entered the system space and began to concentrate on preparing lessons.First of all, I made up the lecture content and schedule during this period, and then prepared the lectures to be taught in the next two days in detail, and found a few exercises, and prepared to turn them back as homework for the girls.

After doing this, Lin Jinglan found that she had spent nearly four hours and felt very tired.She came out of the space, washed up in the dormitory, and chatted with her roommate for a while, taking it as a rest.

After climbing into bed, she re-entered the space and continued to concentrate on writing what she called the "compilation".

Lin Jinglan called up all the relevant documents she had read in her previous life from the system, and began to list the catalog she wanted to compile.

The first part, the brain difference between the sexes... The second part, the difference in thinking between the sexes... Subdivide the catalog... Fill in the literature in the system one by one...

Lin Jinglan had no choice but to come out of the system space until she had a splitting headache, worrying that she had only completed less than a quarter of the compilation, and fell into a deep sleep.

Lesson preparation, lectures, answering questions, creating a collection of papers with spirit in the space, and your own college entrance examination review must not be left behind.

Lin Jinglan didn't have a moment to breathe, and she realized that the time can really be accurately allocated to every minute.Although exhausted, there is also an indescribable satisfaction.

She finally knew how her doctoral supervisor in her previous life insisted on getting up at 1:[-] every morning to start work, and finishing work at [-]:[-] every night, using almost every minute. ascetic life.

Competence combined with interest will produce a great sense of happiness.

Lin Jinglan gave four early morning lectures in a row, and she sincerely felt that the students now are working harder than in her previous life, and everyone finished the topics she assigned every day seriously in the first time.

In the early morning of the fifth day, Lin Jinglan did not give a lecture as soon as she came up, but first hand-copied a solid geometry problem on the blackboard for everyone to try.

After 15 minutes, Lin Jinglan called a stop.There are three small questions in this question, and more than half of the girls have successfully answered the first two questions.

Lin Jinglan asked, "Is it difficult?"

Seeing the girls shaking their heads, Lin Jinglan revealed the answer with a smile, "No one remembers this question? This is the solid geometry of the college entrance examination the year before last."

There was a gasp.

Gu Panpan exclaimed, "Is this a college entrance examination question? Give me a little more time, and I might be able to answer the third question! It's not too difficult!"

Zhao Yumei was also surprised, "However, after learning with you for a few days, I feel that solid geometry is much easier. The place that was a mess after listening to Teacher Li's lecture, now I understand everything after listening to you."

She muttered to herself, "It turns out that solid geometry is not difficult at all. I originally planned to give up the solid geometry problem in the college entrance examination...Oh my God...I'm so stupid."

Lin Jinglan took out a brand-new and exquisite booklet, and handed it to Gu Panpan who was closest to her, "Didn't I ask for leave last night to go home, here, I brought this collection of essays here."

Gu Panpan took it carefully, and was amazed just by looking at the cover, "It's so beautiful, this paper is so good, and it's in color." After opening it, Gu Panpan said, "It's all in English?"

Lin Jinglan nodded, "That's right, the papers still have to be published in authoritative English journals. Although there are authors from various countries, they must write the papers in English."

Gu Panpan looked puzzled, "This... I don't understand."

Zhao Yumei reached out to take it. She thought her English was pretty good, and she shook her head after reading two lines, "No, I don't know any words."

Lin Jinglan understood that now that the college entrance examination has just resumed, many high school students' English is at the level of elementary school students. She even heard that some people filled in all the multiple choice questions in the college entrance examination with option C.

For the previous papers in this collection, she directly used the literature that she consulted from the system, and it was really not easy to understand.

Lin Jinglan said, "You just turn to the page I have bookmarked. That article says that girls have better spatial imagination than boys. Just read that."

That article was written by herself, and the words and sentences were quite simple.

Zhao Yumei read two lines, "Hey, I can probably understand this article."

The other girls surrounded the city, craned their necks to look, and urged Zhao Yumei, "Read it." "Read it for everyone."

Zhao Yumei stuttered and read, "Scholars have done a lot of ...research about the gender differences on math study and the ability ...ability of space and... imagination."

Seeing the dazed faces of the girls surrounding Zhao Yumei, Lin Jinglan took the booklet and said, "Come on, let me translate it for you."

"Scholars at home and abroad have done a lot of meaningful work and effective exploration on gender differences in mathematics learning and spatial imagination, specifically related to..."

This is a review paper. It first listed the research results of previous scientific researchers in turn, and then analyzed them in turn to give a conclusion-women's spatial imagination ability is stronger than men's.

"As for the fact that women's spatial imagination ability is not as good as men's in reality, the study believes that it should be attributed to cultural factors and environmental factors, that is, acquired external factors from family, school, and society..."

After Lin Jinglan finished translating, all the girls stared at Lin Jinglan in astonishment. Lin Jinglan was very surprised, "What's the matter? Didn't I say that women have strong spatial imagination, and I believe this time? Don't you think so before?" I never believed..."

Zhao Yumei came back to her senses, "No, we believed it before...it's just...Lin Jinglan, your English is so good!"

Zhao Yumei suddenly raised her voice, "Oh my God! I've never met anyone with such good English!"

After actually seeing the collection of papers and listening to Lin Jinglan's translation, every girl read that paper carefully again.Although I can’t understand many places, the conclusion of the paper is that women’s spatial imagination is stronger, and they understand it all.

After that, everyone became more enthusiastic about learning solid geometry.

Even Lin Jinglan was amazed, the progress of the girls can be described as changing with each passing day.

The progress of the lecture was much faster than Lin Jinglan expected, and the content she was going to speak was finished many days in advance.The three-dimensional geometry stage test, which determines the outcome of the competition, is still a week later.

Lin Jinglan thought for a while, "I'll talk about another way to solve solid geometry problems, and prepare a way out for everyone during the college entrance examination."

"Everyone knows that plane geometry problems can be solved analytically, establish a coordinate system, coordinate each point of the geometric figure, and then convert the geometric problem into an algebraic problem. You only need to calculate."

"Three-dimensional geometry can do the same. Now I will tell you the analytical method of solid geometry."

"However, during the college entrance examination, unless it is absolutely necessary, everyone should not use this method."

Lin Jinglan started slowly from the three-dimensional coordinate system, the definition of vector, and the calculation of vector.

Two days later, after Lin Jinglan explained a sample problem with an analytical method, the girls understood it all and exclaimed in amazement.

"To prove that a straight line is perpendicular to a plane, you only need to prove that the product of two vectors is zero, so simple!"

"This is basically turning a proof problem into a calculation problem!"

Lin Jinglan nodded, the essence of analysis is to algebraize geometric problems.However, he still warned, "During the college entrance examination, unless it is absolutely necessary, do not use this method. Because this method may not be included in the standard answers for the college entrance examination. If the marking teacher does not understand it, it is likely that the score will not be given."

"Also, don't use this method during our competition this time, lest Teacher Li not give you points..."

Before Lin Jinglan finished speaking, the classroom door was pushed open with a bang, and a large group of boys poured in. Fang Yuntao stood at the front and said, "I heard that you talked about a new method of solid geometry, tell us about it too." , so that the game is considered fair competition."
