Chapter One: The House of the Future

The future house can be great! Make your life comfortable and save energy.

In hot summer, other people's homes need air conditioning to cool down, so you don't have to worry about the heat when you live in this house. Because it can absorb hot air and release cold air stored in winter, which makes you feel cool. In the cold winter, it will release the hot air absorbed in summer and make you feel warm as spring.

It's raining, and there's a clatter on the roof of other houses, but not this one. Because there are countless small roars invisible to the naked eye on the roof, they absorb rainwater, discharge it into the pipeline, and after automatic purification, it flows to an underground pool for storage as tap water. This is real "pure water"! No pollution, save water resources!

When there is the sun, this kind of house can use solar energy to generate electricity besides storing hot air. In this way, there will be more electricity in our country, and there will never be a power outage again.

The earthquake is coming, don't panic, calm down, go to the switchboard room in the basement, press the red button, the protective cover system will start immediately, and the house will be protected by a transparent big ball.

If you want to live in a different environment and don't want to change your house, don't worry. Just press the blue button in the switchboard and enter the specific location. Wait a while, and then when you go out, you will be surprised to find that you have come to another world.

The future house is really great. I really hope this day will come soon.

Chapter II: The House of the Future

I came to the home of my good friend Wang. This is a villa. It is made of light plastic foam and can move at will, but it has unique stability. When it touches the ground, it sticks to the ground as firmly as a brick house.

As soon as I entered the door, my eyes lit up and the whole room lit up, but there were no lights on the roof, only six big and bright mirrors. I asked Wang with questions, and Wang said, "I used the principle of solar reflection." The sun shines on the mirror and then is reflected by it. Isn't that room much brighter "I can't wait to ask again," that night? Wang told me: "There is a solar energy storage device installed on the roof, which automatically stores it for 5 minutes every day. By that night, there will be enough energy to light the house, which is convenient and economical. On the other hand, solar energy can be converted into fire and electricity to do other things. "Hearing this, I was shocked.

Then, take Wang's hand and visit his bedroom. When I came to his bedroom, I saw six color buttons on the bedside at a glance. I'm confused. I asked Wang what these buttons were for. Wang pointed to them and said to me, "The top four buttons are temperature adjustment buttons, the red button is the temperature people need in spring, the green button is ... the black button is the temperature people need in winter, and the first button below is the one for eating." The second is the drink button. When you press it, many drinks will pop up, and you can choose freely.

Then, he showed me around the study, computer room and so on. All this is amazing.

Going home, my heart is still echoing the magical environment just now.

Chapter III: Home of the Future

A sweet dream began again ... future house, future house, I finally have a future house! There are four red, yellow, blue and green buttons at home, which have many natural functions.

Press the red button and the house will move. In spring, it will take you to see the humid tropical rain forest and let you get close to nature; In summer, it will take you to the quiet seaside and let you listen to the sound of the sea; In autumn, it will take you to the distant forest and let you relax happily; In winter, it will take you to the mysterious northern Europe and let you experience the snow-white northern customs. ...

What is the use of the yellow button? Haha, of course, I changed the color of the wall. In the early spring, the wall will turn into a vibrant green, which makes people sigh as soon as they enter the door: "A year's plan lies in spring!" ; In midsummer, the walls will turn cool blue, so people won't feel hot anymore; In late autumn, the walls will turn yellow to let people know that the leaves should fall; In the dead of winter, the walls will turn red. Look at this color, the whole body will warm up.

When you press the blue button when you travel, the house will automatically shrink and then fold, so don't worry about the contents being crushed. Put the folded house in a backpack, even in a strange place, you can find an empty place to enlarge the house. In this way, no matter where you go, you can return to your warm home.

Press the green button, and what you want will be served automatically. If you want something, it will be ready for you.

I was awakened by the surprises in my life. Although this is just a dream, I firmly believe that as long as we get on the science express, we can realize our dream!

Chapter four: the house of the future

The house in the future will become more magical.

The future house can disappear without a trace in the sun, as long as it can appear immediately at night. In fact, it's not disappearing, it's just invisible, and it seems to really disappear after being invisible. Does not occupy land, does not hinder traffic. It can also avoid danger, and natural disasters such as typhoons and earthquakes have no effect on it. If the typhoon and earthquake are quite severe, it just shakes and can't collapse. As for other minor hazards, it is safe to live in it.

The wardrobe of the future can be turned into a special machine, which can replace the current washing machine to wash clothes for the owner. It can automatically clean and iron the changed clothes, even if the clothes are dirty, it will not be difficult to beat.

The wall of the future is more peculiar. There will be a special button on the wall. Just press this button and many Vulcan cups will appear around the wall. The light of these Vulcan cups is much brighter than the lights. It will make the house as bright as day, and any Vulcan cup will rotate, so there will be an underground passage on the wall. When entering the underground passage, the wind will not blow and the earthquake will not happen, which will better protect people's safety and property.

In the future, the floor can be turned into an ice rink for us to play, and it can also be turned into a singing stage for us to sing and make our life happier.

The future house is amazing. I will study hard and make progress every day to build such a magical house.

Chapter 5: The House of the Future

The present house has many shortcomings: there is no one at home, and no one at home knows that thieves have come to steal things; If it rains and there is no one at home, the home will get wet; Even if someone is at home and it rains, the air at home will not be fresh if the windows are closed; If the destination is far from home, there will be a lot of walking ... so I will invent a smart house.

The door of this kind of house is very special, and it is made of a material that will not be damaged by rockets. There are also three super suckers, a fingerprint reader and an infrared reader on the door. As long as the thief comes, the sucker will hold him firmly. When the master came back, he pressed the button and the thief was sent to prison in an instant. That infrared discriminator can also distinguish thieves. In addition, when a thief comes, the door will automatically call the police.

The glass in this house has several advantages: sound insulation if you want, and no sound insulation if you don't want. As soon as the dust falls on the glass, the glass will automatically purify the dust into oxygen and store it in the container. When it rains, the water blocked on the glass will replicate and then flow into a big "pond" underground through many pipes. When there is no electricity, solar energy, hydropower and wind power will supply the whole house with electricity. If the destination is far from home, you can make a "gimmick" of the house-fold it up and put it in your pocket. Or sit at home and click a button, the house will shrink and fly into the air, and it will be delivered to the destination accurately. The host can enjoy the warmth of home anytime and anywhere.

With the development of science and technology, I believe this kind of house is no longer a dream. Before long, this kind of house will definitely appear in this world!

Chapter 6: The House of the Future

With the development of science and technology, buildings have mushroomed, and villas and apartments are readily available. But have you ever thought about what the house will look like in the future? ——

The future house is small, easy to shrink and very portable. This kind of house is made of high-tech cement, which is not easy to deform and flexible, and is the best choice for architecture. As long as you shout "open sesame" at this door, it will open automatically. The surrounding walls will change color according to your mood. When you want to watch TV, the robot nanny will take you to the living room, and a 43-inch TV comes into view. As long as you sign up for the program you want to watch, the robot nanny will debug the search for you, even if it is outdated. When you want to relax, the robot nanny will take you into the sauna and give you a full massage to make you feel refreshed immediately. Come to a luxurious dining table for four on the second floor and put this bunch of roses on the table. At this time, the robot chef will order for you. As long as you gently order the dishes you like on the menu, the robot chef will go back to the kitchen and get busy. Soon, the delicious food will be baked! There is beautiful music in my ears, and eating while listening to music is simply enjoying it. When you come home from a busy day and want to have a good sleep, the robot nanny will take you to the bedroom on the second floor. There is a beautiful lullaby from the bedside speaker, and the bedroom window has good sound insulation effect. Even if the sound outside reaches 65,438+0,000 decibels, the room is still quiet. When you are lying in bed, the robot security guards will start patrolling. Back outside, the trees in the yard are lush. Every day, the robot gardener will water you to kill insects, so you don't have to worry about the tree dying.

There are many different houses in the future, waiting for us to invent and create. Students, let's work together!

Chapter 7: The House of the Future

The house where human beings live in the future will never be like the tile-roofed house or building now, but a super-high-grade house with special functions, convenience and safety.

This kind of houses are super high-rise skyscrapers, which can solve the problem of human housing congestion well.

"That tall house must have gone up by elevator, right?" Many people may ask this question. In fact, elevators didn't exist at that time. The top door of each building is equipped with advanced timing locks. As long as you hold the equipped time key and say "open" to the time lock, you can enter the "time channel" of the building and enter your special password in the "time channel" to take you to your home in the shortest time.

The door is also equipped with a laser detector, which has anti-theft function. If a guest comes, as long as the name of the host is mentioned, it will convey the appearance and characteristics of the guest to the host's home in the shortest time through the laser detector. If the host welcomes him to visit, just press the "welcome" button at home and the guest can enter the "time channel" and go directly to the host's home without entering a password. On the other hand, if the host refuses, press the "Reject" button.

This kind of house is not only convenient, fast, safe and anti-theft, but also has the functions of flood control and earthquake prevention.

Because the shape of the house is not an ordinary three-dimensional shape, but a lotus shape. If there is a flood, it will automatically leave the ground and float on the water. After the flood, the house will be tied to the ground again. If there is an earthquake, it can also take people off the ground in advance to avoid natural disasters.

This is the house of the future.

Chapter 8: The House of the Future

After 20 years, the biggest change in the world will be the number of houses.

This kind of house is ultra-thin and automatically designed by computer, which can be enlarged and reduced. The greater role is extremely attractive, and nothing can be broken.

When you come to your door, you have to enter your fingerprint to get in. If your fingerprints are not saved, you can't go in, no matter how hard you try, unless the owner allows you.

When you walk into the house, you will see some beautiful wind chimes, which are also controlled by computers. When the computer finds a guest coming, the wind chimes will be controlled by the computer to make beautiful music.

The first floor is the living room. There are only a few pieces of furniture in it, and the rest are out of your sight. As long as the owner regrets: "xxx comes out." The furniture will be placed in the predetermined position immediately.

There is a kitchen on the second floor. There is a computer set up in the kitchen to teach people to cook. It will teach you all kinds of dishes from all over the world. As long as you want to learn something, it will demonstrate first, and then correct your mistakes in the process of cooking.

On the third floor is the bedroom, and there is a computer-like watch at the head of the bed with the number 1-9 written on it. If many people come here as guests and don't go back at night, just enter the number and there will be more beds. So guests don't have to spend money to stay in the hotel.

This house has many functions, and I can't finish. Please come and visit!
