My courtyard shelter

Early the next morning, after breakfast, the tour officially began. All students wore a small safety helmet, which was said to be specially made by the factory for the visiting students. read

The first stop of the tour was in the lobby of the office building. In the middle of the lobby was a set of models of desalination plants.

The model is divided into first-phase project, second-phase project and third-phase project.

The commentator is a young woman in her twenties. Her Mandarin is very standard and her voice is nice.

"Students, do you know how big the ocean is?"

"Big, big!"

"I have watched "One Hundred Thousand Whys" and 70% of the earth's area is ocean."

The commentator smiled happily and said, "This classmate is right. Let's applaud and encourage him."

"Pa bang bang..."

“To be precise, the total area of ​​the ocean is approximately 600 million square kilometers, accounting for approximately 71% of the Earth’s surface area.

There are about 500 million cubic kilometers of water in the sea, but only 6% is suitable for human consumption. "

After the introduction, the commentator asked: "Does anyone know why there is so little drinking water?"

"Because sea water is salty, you can't drink it. You can only drink fresh water." Some students responded.

"Yes, but is there a way to turn seawater into fresh water?"

All the students shook their heads.

The commentator smiled: "Today, the factory we visited can turn seawater into fresh water that we can drink. Do you want to know how it works?"

"think!"

Coco held her sister's hand, and the two of them walked at the back of the team. As little girls, they were not interested in factories or machines at all.

"The little classmate in the back wearing blue clothes, please come to the front?"

Maybe it was because the skirt Lele was wearing was the same color as the ocean, so the commentator specially called the other person to him.

Lele walked forward coyly. She was a bad student and was usually most afraid of the teacher asking questions in class.

"This classmate, what is your name?"

"My name is Xu Le."

"Okay, classmate Xu Le, is your home short of water now?" the commentator asked.

"Que." Lele nodded.

The commentator continued: "Can you give an example from yourself?"

Lele first looked back at her sister, then at Teacher Ding, and finally replied:

"I used to take baths in the bathtub. There were a lot of bubbles in the bathtub. It was so comfortable..."

"what about now?"

"Grandma said you can't use the bathtub to take a bath and you need to save water. Now our family can only use a shower to take a bath." Lele said distressedly.

"Classmate Lele, how often do you usually take a bath?"

"I have to wash it every day. Mom said I won't let him go to bed until he takes a bath."

The head teacher, Teacher Ding, quickly pulled Xu Le back and gave the instructor an apologetic look.

"Ahem..." The commentator quickly adjusted his mentality and continued: "Through the example of Xu Le just now, we all know that water is very tight now. Does anyone know the reason?"

"Because it's not raining anymore."

"Yes, the whole world has been in drought since last year. If this continues, no one will even have water to drink."

"ah……"

"What should we do?"

"After you finish visiting this factory, you don't have to worry anymore. Now, let's set off!"

After the commentator finished speaking, he took everyone on several tour buses parked at the door. The factory was too big to walk, and it would easily cause heatstroke among the students.

In the car, Teacher Ding explained to the commentator sitting beside him:

"Miss Peng, don't mind. Xu Le didn't mean to cause trouble. Their family's economic conditions are indeed very good, so they usually use more water than ordinary families."

"Teacher Ding, you should call me Xiao Peng. It was my own mistake. Classmate Xu Le is fair and fat. I should have thought that her family's conditions are unusual." The commentator said with a bitter smile.

"Xiao Peng, don't blame yourself too much. It's just a small mistake. Just try harder next time." Teacher Ding comforted her quickly.

"It's okay. It's a good thing to learn from the experience and gain wisdom."

Teacher Ding looked at the person in front of him again and asked doubtfully: "Xiao Peng, why do I feel like I have seen you somewhere before?"

"I used to work at Yanjing TV Station. Teacher Ding, you may have seen the program I hosted!"

"Yes, yes, when you said it, I immediately remembered it. I quite like watching your program. Why can't I find follow-up resources online now?"

The commentator didn't answer and asked instead: "Teacher Ding, you haven't turned on the TV for a long time, right?"

"Oh, the TV broke before and the repair cost was too expensive, so it never got repaired."

"No wonder! In fact, not only my program, our entire TV station has been banned." The commentator briefly explained the cause and effect of the matter.

Speaking of which, this matter is also a hot topic recently.

Since the country entered a state of emergency, in order to save resources, only one TV station has been retained, and that is Daxia TV Station.

All TV stations in other states, cities and counties have been temporarily banned.

Teacher Ding sympathized: "Then you have been transferred to the factory now?"

The commentator shook his head:

"No, I work in the education department now. The leader saw that I am a host, so he arranged for me to be a commentator here."

"That's it." Teacher Ding suddenly realized.

…

After visiting all the way, the students finally came to the core workshop of the factory.

"Students, this is the salt extraction workshop, covering an area of ​​more than 2,000 acres, equivalent to the size of 125 football fields. After this process, seawater will completely become fresh water."

"Teacher Peng, how much fresh water can be produced here in a day?" A student raised his hand and asked.

"This is a good question. The desalination plant we are visiting now has become the largest desalination plant in the world with only the first phase of the project.

If the three phases of the project are completed, it can produce 40,000 cubic meters of fresh water every day, and the annual production capacity of fresh water will reach 2.7 billion cubic meters, which can meet the needs of 50 West Lakes."

"Wow..."

The students exclaimed, although they did not know how big the West Lake was.

"When you grow up, do you want to work here?"

"Yes!"

"Okay, then you must study hard. Only by getting into college can you become a useful person for the country."

Lele, who was standing aside, was a little confused for a while, because her father told her that it was enough to study hard, and she and her sister just needed to live comfortably for the rest of their lives.

After visiting the desalination plant.

In the evening, the students were taken to the nearby beach by the teacher. They were not here to play, but to pick up garbage.

Looking around, this large beach belongs to the water source protection area. Because of the strong protection, it has become a paradise for seabirds, which is a rare sight.

The next day, when they got up, the students picked up garbage all morning.

Fortunately, Yang Lina prepared sunscreen for the two sisters in advance, and the sun was weaker in the morning and evening, so the twins did not get tanned.

In the afternoon, this spring outing finally ended, and it also left an indelible impression on the students.
