"Then let's start answering today's question, Babe, what's the question this time?"

The light curtain flickered, and a few lines of text emerged.

1. Name the scientist in question.

(1) Who was curious about the apple landing, so he discovered gravity?

(2) Who was curious about the steam coming out of the kettle and improved the steam engine?

(3) Who has been withdrawn since childhood, likes to play with the compass, has a strong curiosity about it, and founded the theory of relativity?

(4) Who was curious about the chandelier shaking and invented the clock?

(5) Who is curious about hens hatching chicks and tries to hatch eggs for a day?

2. Answer the following questions:

(1) Why do birds fly in the sky?

(2) How many legs does a dragonfly have?

(3) When can I see a rainbow?

"I know, I know, the apple falls, gravity — Newton."

"Well, I also know that chandelier swings to invent the clock - Galileo."

"I know two: Watt's modified steam engine, Edison's hatching eggs."

"I know the rest: Albert Einstein created the theory of relativity."

So, Ding Xuecheng said to Beibei: "Beibei, in the order of the title, the names of scientists are: Newton, Watt, Einstein, Galileo, Edison. ”

"Congratulations, 50 points awarded. Please keep up the good work. ”

"Let's discuss the following three questions before answering, and strive to be accurate and complete."

"I went back yesterday and read about insects, and I'll answer." Yanyan didn't answer yesterday, she went back and tutored the relevant knowledge, and then said word by word: "Dragonflies are also insects, 3 pairs, 6 legs." ”

Kiki: "Birds have wings to fly." ”

Binbin: "Ostriches also have wings and can't fly, which means they have to be lightweight." ”

Ding Xuecheng thought about this problem before entering the magic mirror space, and also joined the discussion: "Some insects and birds are good at flying, and the main reasons for having wings and light weight are the main reasons, but there are other reasons that cannot be ignored: first, they need air. If there is no air, the bird does not have the motivation to rise. Without air, birds cannot fly. Secondly, many of the structural features of birds themselves are also suitable for flight. ”

"Well, yes, the bird's bones are hollow and lightweight." Yeon-yeon softly agreed.

"The bird's body is streamlined and has feathers on the surface of the body, which reduces air resistance." Kiki also actively chimed in.

"Birds have particularly well-developed pectoral muscles, which can powerfully drive the wings to flap and provide strong power." Yeon-yeon added again.

Ding Xuecheng read the introduction of the Wright brothers and brought out the knowledge in it: "Human beings once dreamed of realizing the flight of human beings, and the ancients once tied wings to their bodies and jumped from a high altitude, but they were unsuccessful, why is this?" This is because the person weighs too much and must have large enough wings if they want to fly. But to drive such large wings, humans need to have more developed muscles, which humans cannot do. ”

Yeon-yeon: "Airplanes were developed by studying the flight of birds. ”

Ding Xuecheng: "The fuselage of the aircraft is made of alloy material, which is light and strong, the engine provides power, and the propeller produces lift, so that the huge body of the aircraft rises into the air. ”

Kiki: "A lot of planes don't have propellers now, helicopters do have propellers. ”

Binbin didn't interject, as if the questions were too simple, and he didn't bother to rush to perform. When the critical time came, seeing that everyone couldn't answer, it was time for him to show his basic skills, and explained loudly: "The wing of the fixed-wing aircraft is designed to imitate the bird's wing, the front edge is thick and then thin, and the lift is generated when the height is thrust forward, these knowledge is called fluid dynamics, and this is how the fixed-wing aircraft flies into the sky." ”

He paused, looked around proudly, and continued: "Airplanes were developed on the basis of bird flight, and compared with the two, each has its own advantages. Aircraft have advantages in speed, altitude, persistence and load capacity. And the agility of birds is incomparable to that of airplanes. Birds can take off and land in more situations, can turn at any time, and perform a variety of difficult maneuvers, and hummingbirds can fly upside down, which is incomparable to airplanes. So, we have more to learn from birds, they give us more inspiration, they are our mentors and friends. ”

"Well, that's a good point. One last question, when the sun comes out after the rain, sometimes you can see a rainbow. ”

"You can see it next to the fountain when the sun is out."

"At noon when the sun is out, go to the fountain in front of the building or square, and you can see it."

"Then why can't you see it sometimes?"

"Angle, right?"

Ding Xuecheng and the two girls, you look at me, I look at you, I don't know very well.

With a look on his face, like a singing actor, he shook his sleeves and said: "Rainbows can usually be seen in the sky after rain or in places where there are waterfalls, because there are many small water droplets in the air at that time, and this phenomenon is more obvious. Since the small water droplets gather to form a Mitsubishi mirror structure, the white light of the sun is refracted in the water droplets, causing it to disperse into seven monochromatic lights, so a seven-color rainbow appears. And because the refractive index of red light is smaller than that of violet light, the outer layer of the rainbow is red and the inner layer is purple. One must stand between the sun and the rainbow and face the rainbow in order to see the rainbow, i.e., the rainbow appears on the opposite side of the sun—the morning rainbow in the west and the evening rainbow in the east. ”

……

"Okay, I'll summarize the answers to these questions, and this event is done."

Ding Xuecheng sorted out the answers to the three questions, and then answered them one by one, this time he got 50 points, 10 points, 30 points, a total of 90 points.

At the end of the event, Bei Bei projected two lines of large characters on the light curtain:

"Curiosity is a valuable psychological quality for teenagers."

"I have no other talents, I just have a strong curiosity; I don't have any other talents, but I like to get to the bottom of things. - Albert Einstein. ”

After the consciousness of the three friends returned, Ding Xuecheng immediately checked his character attributes.

Ding Xuecheng was about to complain to Bei Bei that "points are difficult to obtain" because he had gained too few points this time, and when he saw the final reward, he almost cried grateful: "Ah! Learning machine, and one more chance to draw! ”

"The learning machine has been put into the access space, and I will study it when I go back. Your mental power is only 0.6 points, so you have to return to the lottery soon, and you have to use the physique enhancement liquid for grandma. ”

Ding Xuecheng secretly slandered himself: "I want to know the information of the learning machine, I will ask after I go out, and I have to pay more points, Beibei is too black-hearted!" ”

But thinking that the mental power was not much, I had to click on the exchange list and greeted: "Beibei, I'm ready, the lottery begins!" ”

The light flashed line by row, and finally stopped at "charm", Ding Xuecheng almost cried: "What's the use of this? Wasted! ”

Beibei's small eyes flew in the big sockets, and the huge black nose was raised high: "Hehe, maybe there is an unimaginable use?" ”

"Forget it, go back and treat grandma. Oh, and by the way, there's another question: should I touch my grandma when I give her an enhancer? ”

"No, within a certain distance, you need points to increase the distance."

"How far do you get points?"

"1 meter."

"Well, that's fine! How does my grandma react when I use it? Could it be that it is also a cool feeling in the center of the eyebrows? ”

"The last time you used the mental power enhancement liquid, it was absorbed by the center of the eyebrows, so it felt cool; Physique enhancer is absorbed into the skin without any sensation. ”

"Oh, then I'm relieved!"

"Spend 2 points deducted."

"How is it 2 points? That's just one question! ”

"Two problems: the distance of using the enhancer, and the feeling of using the physique enhancer. This answer is 1 point. ”

"Ahh 3 points less,...... You're so dark~"

"Wrong! I'm fair. ”
