Smart life theme

On that day, my family came to an uninvited guest. I opened the door and asked him to come in.

This is the strangest person I have ever seen: the face of the square, a pair of eyes like a light bulb, shining red. Under the nose of the triangle is a rectangular mouth. He was wearing a linen coat, wearing a straw hat and two plastic bags tied to his feet...

"Is this the earth?" he said word by word.

I feel inexplicable: "Of course, are you an alien?"

“Yes, I am a visitor from XX Planet. I heard that the life of the Earth has greatly improved and I have come to experience it. So, today I came to Shaoxing, which is known as the “land of fish and rice”, to feel the high-tech. Life." The alien friend spoke without any tone.

"Hehehe..." I smiled and asked him to sit down, thinking and asking: "What is your name?"

"Wisdom." After he answered, he began to look at my home. In fact, my home is very ordinary. A spacious living room with many mahogany furniture and a wide-screen TV in the center. As for the freezer, air conditioning, it’s not surprising, every family has it. However, the smart classmates seemed to be surprised, their eyes were ten times bigger and an unbelievable look.

"God, is your family a big money?"

"Ha ha ha..." I laughed and leaned forward. "What international jokes, my family is the most common medium-sized family, where is the big money! You want to ask these appliances and furniture? Haha, you don't know, we Shaoxing The city has gradually entered the era of wisdom, and life is increasingly inseparable from high technology!"

"Really?"

"Of course, if the previous Shaoxing is a gray stone, then now Shaoxing has gradually developed into a gleaming diamond! Well, this is the most common electric freezer, do you know what the principle is?"

"what is it?"

"Electric freezer is the purpose of cooling by evaporative cooling or gasification endothermic. The throat of the electric freezer is equipped with a refrigerant commonly known as Freon: commonly known as snow species. The commonly used one is two. Fluorodichloromethane is a colorless, odorless and non-toxic gas with a boiling point of 29 ° C. Freon is pressurized by a compressor when it is in a gaseous state, and after being pressurized, it flows through a throat to a condenser at the back of the electric freezer, and is cooled by a heat sink. After that, it condenses into a liquid. After the liquid freon enters the shutter of the evaporator, it is immediately turned into steam due to the pressure of the compressor, and the latent heat of vaporization is sucked into the air and food in the electric freezer, causing the internal cooling of the freezer. After the vaporization, Freon is pressed back to the condenser outside the box to dissipate heat and then become liquid. This cycle is not enough, and the heat energy in the freezer is pumped outside the box. Therefore, the inside of the freezer is cold!" Put a little KISS expression.

Wisdom heard the clouds, but still ordered the electric head, and asked: "It seems that the big city of Shaoxing is getting more and more improved! However, I still don't believe it. What is your rural area in Shaoxing? ”

As soon as I heard it, I replied with a smile: "Smart friends, you are in the countryside now! Where is the big city like this?"

"What?" Wisdom almost jumped up. "Do you scare me? Is this rural? This is absolutely impossible!" How can rural areas be so "rich"?

"What is impossible? Is the countryside always a poor and sour? Go, I will take you to the farmland to see!"

So, we walked side by side to the field. Wow, look around, the field is alive, the lovely plants are waving to us. More than a dozen lawn mowers were well-organized, and the farmers looked at their farmland cheerfully. Ah, the sweaty figure of the peasant who once sweated and worked hard has ceased to exist!

Finally, I saw the eyes of wisdom revealing the color of admiration. He said with emotion: "Yes, Shaoxing is already improving! In terms of material and spiritual life, it has been continuously improved! High-tech era, wisdom Life, Shaoxing, is really good! It seems that I have to go back to my planet and carry forward technology!"

I nodded proudly and deeply felt the convenience and happiness that high technology brought to people. I can live in the age of happiness, and I am really happy!

Later, the alien friend "returned with full load" and went back to his own planet.
