The next morning, after breakfast, the tour officially began, and all the students wore a small hard hat, which is said to be specially made by the factory for the visiting students.

The first stop of the tour was the lobby of the office building, in the middle of which was a set of models of a desalination plant.

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

The narrator is a young woman in her twenties, with standard Mandarin and a nice voice.

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

"Big, big!"

"I've seen '100,000 Whys,' and 70 percent of the planet is ocean."

The narrator smiled with satisfaction: "This student is right, everyone applauds and encourages." ”

"Bang Bang Bang ......"

"To be precise, the total area of the ocean is about 360 million square kilometers, which is about 71 of the Earth's surface area.

There are about 1.35 billion cubic kilometers of water in the ocean, but only 2.6 percent are available for human consumption. ”

After the narrator's introduction, he then asked, "Does anyone know why there is so little drinking water?" ”

"Because the sea water is salty and cannot be drunk, only fresh water can be drunk." Some students rushed to answer.

"That's right, so is there a way to turn seawater into fresh water?"

The students shook their heads.

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

"Yes!"

Coco took her sister's hand, and the two walked at the back of the line, the little girl, who was not interested in factory machines or anything.

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

Maybe it was because the skirt Lele was wearing and the ocean were the same color, and the narrator specially called the other party to him.

Lele stepped forward with a twist, she was a scumbag, and she was usually most afraid of the teacher asking questions in class.

"What is your name, classmate?"

"My name is Xu Le."

"Okay, classmate Xu Le, is there a shortage of water in your house now?" The docent asked.

"No." Lele nodded.

The narrator continued, "Can you give an example from yourself? ”

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

"I used to soak in the bathtub, and there were a lot of bubbles in the bathtub, so comfortable and comfortable......"

"And now?"

"Grandma said that we can't use the bathtub to take a bath, and we need to save water, and now our family can only use the shower to bathe." Lele said distressedly.

"Lele-san, how often do you usually take a shower?"

"I have to wash it every day, and my mother said that if I don't take a bath, I won't let me go to bed."

The head teacher, Mr. Ding, hurriedly pulled Xu Le back, and then gave the narrator an apologetic look.

"Cough..."The narrator quickly adjusted his mentality and continued to explain: "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."

"That's right, since last year, there has been a drought all over the world, and if this continues, everyone will not even have water to drink."

"Ah......h

"What then?"

"Once you've toured the factory, you don't have to worry about it anymore. Now, let's go! ”

After the commentator finished speaking, he took everyone to sit on a few tour buses parked at the door, the factory area is too big, it is unrealistic to walk, and it is easy for the students to suffer from heat stroke.

In the car, Mr. Ding explained to the docent sitting on the side:

"Miss Peng, don't mind, Xu Le, she didn't mean to make trouble, their family's economic conditions are really good, so they usually use more water than ordinary people."

"Teacher Ding, you still call me Xiao Peng. It was my own mistake, Xu Le was white and fat, I should have thought that her family conditions were not ordinary. The narrator smiled wryly.

"Xiao Peng, don't blame yourself too much, it's just a small mistake, just make an idea next time." Teacher Ding hurriedly comforted.

"It's okay, it's a good thing to eat a trench and grow wise."

Teacher Ding looked at the person in front of him again, and wondered, "Xiao Peng, how do I feel as if I have seen you somewhere?" ”

"I used to work at Yanjing TV Station, Mr. Ding, you may have watched the show I hosted!"

"Yes, yes, yes, what you said, I remembered it all of a sudden, I still like to watch your show, why can't I find follow-up resources on the Internet now?"

The narrator didn't answer and asked, "Teacher Ding, you shouldn't have turned on the TV for a long time, right?" ”

"Alas, the TV was broken before, and the repair cost was too expensive, so it has not been repaired."

"No wonder! In fact, not only my show, but our entire TV station has been banned. The narrator briefly explained the cause and effect of the incident.

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

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

Television stations in other states, cities, and counties have all been temporarily banned.

Teacher Ding sympathized: "Then you are now transferred to the factory?" ”

The narrator shook his head:

"No, I am now working in the education department, and the leader sees that I am a host, so he arranged me to be a docent here."

"I see." Teacher Ding suddenly realized.

……

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

"Students, this is a salt extraction workshop, covering an area of more than 2,000 acres, equivalent to the size of 125 football fields.

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

"That's a good question, the desalination plant we are visiting now, only the first phase of the project has made it the world's largest desalination plant.

If the third phase of the project is completed, it can produce 2.324 million cubic meters of fresh water per day, with an annual production capacity of 727 million cubic meters, which can accommodate 50 West Lakes. ”

"Wow......"

The students exclaimed, although they didn't know how big the West Lake was.

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

"Yes!"

"Okay, then you have to study hard, only when you are admitted to the university can you become a useful person to the country."

Lele, who was standing on the side, was a little dazed for a while, because her father told her that it was good to study hard, and she and her sister just had to live comfortably for the rest of their lives.

After visiting the desalination plant.

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

As far as the eye can see, this large stretch of beach is a water conservation area, and it has become a haven for seabirds due to its strong protection, which is a rare sight.

When I got up the next day, my classmates picked up another morning's garbage.

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

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

: Ask for a referral ticket and a commuter pass!
