Fan Jingjing suddenly felt a chill on her body at this time, and she realized that it was not a good thing to create many science students.

Students are prone to developing problem babies. Fortunately, so-called science students need to have the ability to research, and they don't need to be fully answered.

Just develop their hands-on problem-solving skills.

After Fan Jingjing made a statement to the student begging for mercy, she continued to attend class.

"The most complex ecosystems are tropical rainforest ecosystems, where humans live mainly in artificial ecosystems dominated by cities and farmland."

The following questions were about to move again, Fan Jingjing thought for a while, and could probably guess the other party's questions, but she still glared and asked them to summarize the questions at the end.

At that time, I can still remember some of the big questions on the minds of the students.

"An ecosystem is a system that sustains all the processes of life from birth to death, and these animals or plants depend on each other for survival. It's like chickens eat bugs, bugs can draw nutrients from food, and chicken droppings can make plants grow well. So that they can survive without relying on external objects, then they are an ecosystem.

Ecosystems are open systems, and in order to maintain their own stability, ecosystems need to continuously input energy, otherwise there is a danger of collapse;

Many basic substances are constantly circulating in ecosystems, which are a major structural and functional unit in the field of ecology...... Of course, we humans are also a part of the ecosystem, and we are even the biggest destroyers of the ecosystem......

Fan Jingjing noticed that when she talked about this, the students below had already begun to have blurred and misty eyes, and she noticed that she was talking about the place that was out of reality again, because there were too many proper nouns for them, and it was too unrealistic for them.

In the Tang Dynasty, although ecological destruction has gradually appeared in human life, human beings do not have much feeling for this kind of reality, because even if floods, droughts and various natural phenomena exist in the natural environment, human beings can only strive to survive when these natural phenomena occur.

As for what phenomena have occurred more and what phenomena have occurred less, they do not have much feeling, and perhaps some officials who have specialized research will have some information, but other officials are not clear.

For example, the reason why the drought occurs now may not have something to do with the Xiaoice period, but the observation of sunspots is simply difficult to observe in this era.

When new technology is constantly introduced, there will be more discoveries and deductions, and the development of new technology seems to be related to industrial technology, the more exquisite industrial technology, people can develop, but more sophisticated instruments, and more sophisticated instruments represent the pace of science, can go further.

However, exquisite instruments and equipment are almost prepared for military and life, and if they are not used in life or military, they will gradually be eliminated.

But not good things will be welcomed, if people do not have the economic basis to use these goods, or the use of these goods, will not improve their economic base, so as to ensure that people can continue to use, the invention will be temporarily eliminated from human life, which is why many inventions have not been able to survive in the history of China.

But in the end, there is no way to get the right answer to whether science is good or bad for human beings.

But the development of science is for military purposes and further.

At the critical moment of survival, countless people want to get a stronger way to protect themselves and deal with the enemy, and all kinds of inventions are constantly produced.

Later, some inventions were used in people's livelihood, and they are very useful, such as the network that Fan Jingjing once relied on very much, and now Fan Jingjing also wants to rely on the network, if she carries a mobile phone, and the mobile phone can also be used to communicate, then, this kind of information is accessible, maybe he will become the richest person in the world, but it will probably become the emperor's most vigilant object, in an extremely dangerous situation, maybe the emperor will physically kill Fan Jingjing.

With the use of science and technology, people's lives are becoming more and more convenient, and human beings are consuming more and more natural resources, and the problem of resource depletion has become a problem that human beings need to face.

Life is getting happier and happier, but many people feel that maybe human beings will not survive the 21st century.

Therefore, Datang's slow life also has some benefits, but the slow life, those who can enjoy the benefits are an absolute small number of people, and the majority of people are still on the verge of life danger.

They face all kinds of difficulties every day, and they try to face them with a smile in the difficulties.

At the end of the explanation, it was time to answer the questions, Fan Jingjinghua's explanation time was not too much, but the answering time took up most of the time, and more dolls learned what she wanted to learn during the answering time.

came into contact with a new science, in fact, the dolls asked a lot of questions, which Fan Jingjing may not have thought about before.

Fortunately, Fan Jingjing has a lot of training in biology, elementary school, junior high school and high school.

The cute baby's questions can't be difficult for her, and she can still respond.

Even the questions asked by the cute baby are still myths rather than science, so Fan Jingjing must decipher these myths and let them guide them to science, Fan Jingjing's attitude towards mythology is the same as Confucius's.

"If you really want to prove the existence and validity of life, then you must study biology in a human way.

In fact, many gods are our fantasies, but there is indeed a difference of luck between people and people, whether gods exist or not, and the teacher has no way to determine with you.

But when we pursue science, we must use human means to prove everything, because only when people can prove everything, we can reproduce it, and we can use it on people, because such a truth will be accepted. ”

Wu Xun's children are still hazy in their eyes, but the prince and the princess already understand them.

Perhaps the royal family is the most believing in God, but also the least believing in God, and if the theory of God is not good for the royal family, the royal family can expel this god.

It was their luck to become a royal family, and once they fell from the altar, it was absolute demise for them.

Fan Jingjing looked at the difference between these two eyes, and also sighed, it seems that Niu Yingxiu must be placed on the side of the prince and princess, and Wu Xun must also start a class to teach.

When Fan Jingjing taught, she taught according to her aptitude, but the difference in the degree between the two sides was too big, and the difference in teaching background was too great, so it was not easy to teach.

Although Fan Jingjing made a big blackboard and prepared a lot of chalk, the teaching content would be neatly written on the blackboard every day, and the students below would copy it down, but the students below used a brush to write on the paper, and it took a lot of time to copy.

However, Fan Jingjing did not change their habits, and did not use charcoal, because charcoal is not yet mature, and hands are easy to blacken, and more importantly, the effect of charcoal writing on the current rice paper is not very good, and it is easy to break these papers.

And these children are still young must master the skills of writing brushes, no way, the most important tool for using pens in this era is the brush, even if the pencil is developed, the pencil has no way to replace the brush, only in a small use.

For example, when making some drafts, you can use pencil or charcoal, but it is still difficult to make pencils with the current technology, but with a little improvement of the machinery, maybe the pencil making technology can be broken through.

However, if you want to make precision machinery, you must have further human resources in the blacksmith's iron factory before you can start making machines.

Some machines must be manufactured by machines, so it is said that only after manufacturing a machine can the next machine be produced.

The evolution of machines is the evolution of craftsmanship.

But the brush in Datang is still the most important, so Fan Jingjing believes that these children must master the skills of writing calligraphy.

What's more, most people write calligraphy so good-looking, so when the artwork comes to watch, Fan Jingjing doesn't want to destroy this calligraphy art, you must know that there will be a lot of calligraphy in the future, and the achievements of traditional calligraphy and Chinese painting are historical treasures.

If she made the pencil or ballpoint pen popular, resulting in the later people did not have much opportunity to master the brush, but the various brush masters that appeared in history in the future, just disappeared, you must know that the thin gold body of the Song Dynasty and Zhao Mengfu of the Yuan Dynasty are very famous calligraphers.

What's more, Fan Jingjing still wants Tang Zhuwen Zhou of the Ming Dynasty, these four talents appear, if there are no four talents, then history will inevitably have many regrets, and many beauties will disappear like this.

Fan Jingjing felt that maybe her appearance would bring a lot of changes to the future, no matter how much she controlled it, in order to change her life and make her life better, others would definitely be affected by herself.

She can't be the only one who enjoys a good life and ignores everyone else.

And she has good things to enjoy, the prince and the princess will come to ask for one, in order to ask for one for the prince and the princess, Fan Jingjing has to get another copy for the palace, the problem is that there are so many concubines in the palace, so she has to get a production program for the workshop to do.

But they have already made a production program, let a workshop to produce, and it seems a bit of a waste not to produce externally, so some manpower was used, but with these manpower, other industries were insufficient, so Fan Jingjing had to recruit some more people into Fan's Manor, anyway, at this point in time, there are still many people who actively want to join Fan's Manor.

At the beginning, the people who wanted to join the Fan family manor were almost all unable to eat.

They wanted to come to the Fan family manor to beg for a bite to eat.

Now the people who want to come to the Fan family manor to line up are not the only ones who lack a bite to eat.

People who have food at home want to come to Fan's Manor to get a job opportunity.

Because they found that if his skills were used to produce the things of the Fan family's manor, he could make more money.

I heard that in the workshop of the Fan family manor, most of the income still belongs to the staff, and the Fan family manor only collects a part of the money, so they also want to make more advanced products.

Because advanced products can often sell well, the price is still high, unlike their ordinary products, which have to wait for many days to be made, and no one may buy them.

There are very few consumers in Datang, and even if the people who buy things are relatively wealthy in the family, they will generally cherish and use all the things they buy.

It's not a problem to use an object for hundreds of years, unless the thing is already very wear-out and can't be used for that long.

And the quality of the ancient times is actually not bad, unless they don't have this technology beforehand, otherwise the things made will be used for a long time, or they will be scolded by others.

The whole commodity market, because it is all handmade, the value of the finished product is high, of course, this high is aimed at the common people, if for the rich and noble, even if you take the money of the common people to eat for a lifetime to consume the same item, they also feel nothing.

However, you can imagine that when a rich person spends two months of your salary to buy something, this thing will be more or less cherished, unless it is a super rich person with a net worth of tens of billions, if he has a net worth of tens of millions, he will spend more than 100,000 or 200,000 yuan, and he will still pay attention to it more or less.

So the things he buys will be used for a long time, not like toilet paper in the toilet, which will be thrown away after use.

Having said that, Fan Jingjing has been researching toilet paper, and now rice paper is used to wipe the butt or there is still no way to wipe the poop very cleanly, as for the toilet chip, Fan Jingjing is not used to it, every time she goes to the toilet, Fan Jingjing will secretly hide and wash her fart, if it is not for Fan Jingjing to make condensate to wash her fart, it will be very difficult to wash her farts after going to the toilet.

This also made Fan Jingjing very dislike going to the toilet.

Even with a special condensed water toilet, going to the toilet is still a hardship that Fan Jingjing has to go through every day.

Fan Jingjing felt that it was very hard at this time.

Fan Jingjing knows more or less about the teaching methods of the ancients recorded in the Book of Rites, but she feels that the ancient teaching methods make it difficult for students to raise their interest in learning at the beginning, and often hope that they will grow up and slowly understand the truth in books, especially words, after more contact, so they are often very slow when they know words.

And Fan Jingjing knows that these people can speak regardless of whether they read or not, but the words they speak cannot be matched with words, and the language of Datang is the same as that of later generations, and every place has the language of every place.

Fan Jingjing can only understand Chang'an's language.

The main high-ranking officials will also learn the language of Chang'an, and there is no problem in communicating with high-ranking officials, and there is no problem in communicating with local people in Chang'an, but there are many problems when they go out of Chang'an.
