I have had a wish since I was a child: to be able to talk to animals. I often think: If I can invent a language converter, I can easily talk to animals and make friends with them. Now, at the age of 60, I have finally realized this wish and invented an animal language conversion machine. I designed it to look like a brooch, which is small, beautiful, and easy to carry.

On this day, I took my granddaughter Wenwen to play. After arriving at the zoo, I put on an animal language converter for Wenwen. As soon as she put it on, she told me in surprise: I heard the monkey talking. It was telling its mother that its back was itchy and asked its mother to help scratch it. At this time, the mother monkey really started to scratch the little monkey's back. I said kindly to Wenwen: Wenwen, you can still talk to the little monkey.

Really, grandma? Wenwen said excitedly, "Hello, little monkey!" The little monkey looked over, scratched his ears, then scratched his cheek, and said: Thank you, but how can you talk to me? Wenwen said proudly: My grandma invented the animal language converter, which allows me to talk to you. This is really a good thing. The little monkey clapped his hands.

Wenwen excitedly communicated with the animals. When we came to the giraffe park, Wenwen found a giraffe looking downcast. Wenwen asked the giraffe: Giraffe, what's wrong with you? My neck hurt for a day, but no one knew about it. The animal language converter soon transmitted the giraffe's words. Wenwen quickly told the keepers about the giraffe's neck pain, and they called in an animal doctor to see the giraffe. The giraffe felt much better.

A breeder asked Wenwen curiously: Children, how do you know that giraffes have neck pain? I used the animal language converter invented by my grandma, which allows humans and animals to understand each other's languages ??and enables communication between animals and humans.

When I left the zoo, I gave the animal language converter to the keepers so that they could take better care of the animals here.

Ah, the white wings I have longed for have finally come out! It is a means of transportation in the 22nd century. As long as people wear it, they can fly freely in the blue sky like a bird.

The white wings can stretch freely, stretching out like butterfly wings; shrinking in, like a backpack.

When we go out, we no longer have to squeeze into buses or drive private cars. You just need to tell the white wings where you want to go, and its universal CPS positioning and navigation system will start to work. It will fly you to your destination accurately. It has three speed modes for you to choose from: 1. Sun Wukong type, 100 kilometers per minute, suitable for emergencies. For example, firefighters put out fires. 2. Zhubajie type, 10 kilometers per minute, suitable for office workers. 3. Tang Monk type is 5 kilometers per minute, suitable for the elderly and children.

If everyone uses white wings, will there be traffic accidents in the sky? Of course not. Because they all have their own tracks. This invisible orbit is the magnetic field of the earth. The eight-color wings fly in an orderly manner in this large magnetic field. There is no need for traffic lights or traffic police.

The most bragging thing is that it uses carbon dioxide as power. There is a special motor in its backpack. It can suck in the carbon dioxide produced by humans, convert it into sugar, and then convert it into salt. , and finally converted into electricity. These complex processes are all completed in an instant. Finally, the oxygen is exhausted.

How about it, the white wings are magical enough! I hope the white wings can bring more comfort and convenience to our lives.

It is now 2320. According to 2020, it is 300 years ago. Nowadays, science and technology are very developed. Many things in 2020 Dreams have become a reality at this time, such as maglev trains, jet packs... they have become commonplace, but technology is constantly progressing and developing. Today's scientists are not satisfied with the status quo at all, and want to study higher Technological items.

No, a high-tech product came out this year. It is the "trackless train". As the name suggests, this is a train that does not require tracks. Each of its carriages can be combined in any way. It's a train. It can be taken apart and used as a car. It can levitate in the air like a maglev train, at high or low levels, but without the stringent requirements of a maglev train and at the same speed. The most important thing is that it uses clean energy. There are solar panels on the roof of the carriage, which can convert the sun's light into electrical energy.

Once this train is invented, it may affect students. What students fear most when going to school is traffic jams. Once there is a traffic jam, they may be late. With this "trackless train", late? Doesn't exist. Without road restrictions, this train can fly high or low. It can just go around wherever there is a traffic jam.

Besides, this train is very fast. You can get to school in five or six minutes. If you leave half an hour early, what's the harm in being stuck in traffic for more than ten minutes?

If you have it, traveling will be a convenient thing. Traveling can save a lot of time on the road, and drive your own train for an easy trip.

Say goodbye to the future and return to reality. Imagination is a longing for the future. If you want to make your imagination a reality, you have to work hard.

In 2063, the earth has completely entered the high-tech era. 43 years have passed by, but technology has progressed very slowly.

At this time, they are going to blow up the 5483 asteroid that has escaped from the planetary belt between Mars and Jupiter to prevent it from hitting the earth. Forty-five days after we rushed out of the atmosphere and flew towards asteroid No. 5483, we arrived near the asteroid. We found that it was made of ice, organic compounds and rocks. The asteroid with a diameter of 1km was like a big dirty snowball.

"Turn on the logic computer. We are going to get close to it. There will be some slight vibrations when we get close." The captain said. A spaceship lands on an asteroid. A group of five people put on pressure suits and helmets and got into the pressure chamber. The door slowly opened, they walked to the ladder, and placed an atomic bomb at the core 500 meters above the ground.

Return to the cabin and close the door, take off the pressure suit, press the explosion button that extends for one minute, and fly at 30 times supersonic speed. With a "boom", the asteroid is blown into pieces. Particles, there was cheers in the cabin.

In the 25th century, space has become a tourist attraction for people!

I finally graduated from college! So, I wanted to experience what it would be like to travel alone? I booked an "arrow ticket" to outer space and started my journey into outer space.

The first stop is what I consider to be a “scenic spot”—the comet. In fact, it is just an ordinary attraction. Its highlight is a planet famous for its delicious food. As a food heroine, I only value its food. The most famous place in Comet is the "Dinosaur Restaurant" which is also my favorite place.

When you come to the Dinosaur Restaurant, you will see a dazzling array of delicious food in front of you. The most popular drink is "Meteorite Fresh Milk Tea". When you take a sip of "Meteorite Fresh Milk Tea", you will feel the milk tea "exploding" in your taste buds, leaving a fragrance on your lips and teeth, and the pearls are elastic and smooth. What surprised me was that this meteorite milk tea is not greasy after drinking more. Why do I feel like this milk tea is tailor-made for me! I only drank 26 cups in one go, and I felt pretty good. The shop in the Dinosaur Restaurant is full of small dinosaurs with different characteristics. I picked a small Stegosaurus. Its ancestors fled to the comet in order to survive, and they were also the only surviving pair of dinosaurs at that time.

Then, we rode small meteorites to the second attraction: the Milky Way. The Milky Way is famous because the coral on its river bottom is made of silver. A heroine like me who is not greedy for money should do whatever it takes, right? I was the first to jump into the Milky Way. There is glittering gold inside, as if you have entered a silver world. There are many kinds of corals, everyone likes them. I struggled here for a long time and pulled out half of the coral. Before I went in, my weight was rounded up to 100 kilograms, and the weight of the coral was only 1 ton! Of course, you have to leave a little "regret" before you have the chance to come again.

This joyful trip is still going on, but I will go home first to put away my money. Everyone admires me when they see my "trophies".

This space trip is an eye-opener. I think we should learn more knowledge to explore the space universe and benefit mankind.
