I'm Little Inventors, and I want to invent a foldable house so that I can carry it with me. There are many kinds of folding houses, such as townhouses, apartments and villas ... you really have everything. Folding rooms are very useful. As long as you press the red button, it will immediately shrink into a house the size of a Rubik's cube. You can put it in your handbag. When you arrive at your destination, press the green button, and it will immediately become a beautiful big house. Go in and have a look, ah, it's beautiful! Everyone will give such admiration. Because there are all kinds of furniture in it, it is simply a palace. You will think, where have all the furniture been poked just now? It's impossible to squeeze them all into a small house! Haha, don't worry, just press the pink button to deal with these furniture, and the furniture will jump into a card and then jump out when necessary. You will also think, what if the small house is lost? Never mind, just press the blue button on the conductor and the small house will arrive at you quickly from the lost place.

Okay, I'm done. Do you like this folding room after listening to it?

Today, we had a special composition class in our class. The theme was to introduce our own imaginative inventions, and it was an imaginative exposition. First, discuss with your deskmate what your imaginary invention is, then discuss with the whole class and make a speech. I think that explanatory articles are not easy to write, and children will not be sure, which involves the order and method of explanation. The order of explanation we learn is from the whole to the part, and the explanation methods are examples, numbers and metaphors. Children don't know how to use it, but in the process of communication, it is better than I expected.

The representative work of the class speech is Yu Xinxiu's The Vacuum Cleaner of the Future. She first explained why the vacuum cleaner was invented, because the environmental protection aunts worked too hard to sweep the streets every morning. Vacuum cleaner has three characteristics: color, button and seat. The button can identify the direction and location of the garbage, and the vacuum cleaner automatically picks it up. Environmentally friendly aunts can follow the vacuum cleaner and sit in their seats.

Jaco's Wings of the Future is more interesting. I can put wings on people and fly in the sky. At that time, I was very excited. I wish I had wings. I flew and the children laughed. I can't help laughing!

If I were an inventor, I would invent a bookshelf. Don't underestimate this bookcase. This is not an ordinary bookcase. It looks ordinary on the surface, but there are endless books hidden inside. As long as you say the type of book you want to read, the book you need will appear on the bookcase. For example, if you want to read children's novels, you can say "children's novels" to the bookcase. The bookcase will be filled with books of "children's novels" immediately. However, if you talk about unhealthy books such as "martial arts novels", the red light on the bookcase will light up to remind you not to read too much. If you don't know what books to read, just press the "recommend" button next to the bookcase, and he will help you recommend some books that are suitable for you, so that you can "drill" into the books for fun, but you must study hard and don't gulp down the dates!

This bookcase can not only read books, but also relax people's mood. If you are bored, it will become an interesting book. Just open the book and read it carefully, and you will hear a wonderful piece of music, so you won't be bored.

It is also your good partner: when you are happy, it will turn into beautiful music and be happy with you; When you are sad, he can conjure up interesting books to make you happy. At this time, you will forget your troubles, enter the ocean of books and swim happily in the ocean of books. ...

This is the multifunctional bookcase I want to invent-a good companion in my life.

One day, I was watching TV at home when suddenly a golden light appeared and sucked me in. When I opened my eyes, I came to the future world. A schoolbag and a handbook appeared in front of me. The color of the schoolbag is yellow. I read the instructions and it said, "It can change one color every day." "The shape is triangular and made of special materials, so it is waterproof, fireproof and scratch-proof," I said. I continued to read the instructions and finally knew how to use them.

It has a very big space. Although it is small, it is very big. It can hold all your books, stationery and other extra-curricular books, and you can't feel the weight when carrying things weighing dozens of pounds. It also has a voice system on it and a sensor next to it. As long as you can't walk, just say "fly" and there will be two propellers at the bottom to take you up! I will also bring you a remote control with a mechanical arm. There are four buttons and four arrows pointing in different directions. Press the up key to fly up, press the down key to fly down, and press the right key to fly right. It also automatically packs schoolbags. As long as the schoolbag is messy, its mechanical arm will put it away and wait for five seconds before putting it away. It can also hold an umbrella automatically. As long as the sensor senses rain, it will hold up a big umbrella from behind. This umbrella is very big, so don't worry about getting wet. Security is also guaranteed. It will call the police when it meets bad people, and it will automatically navigate to send you home safely. At night, pressing the green button will turn on the flashlight and light up the road ahead.

I travel around the world with my schoolbag on my back. Suddenly, a golden light sent me back to reality. Oh, I wish I had such a schoolbag!

My ideal is to be a great inventor. I want to invent a small robot when I grow up, because my mother does housework very hard every day. With a small robot, she can help her with housework and give her mother more time to rest.

Of course, I also want to invent a robot teacher. Teachers should assign homework in class. When my parents are not at home and I don't know what to do, he will accompany me to study, so that my study will be easier and my grades will be better and better.

I also want to invent a robot traffic policeman. No matter whether it rains or blows, you can see the busy figure of the police uncle at school every day. With the robot traffic police, the police uncle doesn't have to work so hard. They can control the police by computer. From then on, the road will be wide and there will be no traffic jam at any time.

Please tell me what you need, and I will invent many new inventions to make our life more convenient. I am Little Inventors, believe me, I will be successful when I grow up.
