My invention, the fourth grade composition one.
He was born in a happy family. From an early age, his parents told him to dare to innovate and love to invent. Dongdong's father is an inventor, and his works have won many awards. He often teaches Dongdong to do some small creations.
Once, Dongdong and his father went to the park to participate in tree planting activities. He saw people digging a hole in the ground with a big shovel, then carefully putting the saplings in, then burying the soil, and finally watering the saplings. Dongdong clearly remembers all the procedures. He also took a small shovel and turned the soil hard. Before he planted the second tree, he was sweating and out of breath. Dongdong thought it would be nice if there was a machine that could grow seedlings by itself. At that moment, a light flashed in his mind. Have a drink. Dongdong shouted and ran home to take out an empty bucket, eight sticks and some screw parts. He fixed eight sticks to the bottom of the bucket with many screws, erected the bucket, emptied the bucket, pressed the tree down, poured some water and covered it with soil, and it was done.
Dongdong's invention is deeply loved by people.

My invention is called. Three shoes? It can help my mother to alleviate the troubles in life. This invention is my first bold invention. At first glance, it is no different from ordinary casual sports shoes. Look carefully, there are three buttons on it, red, yellow and green. Every button has a change function, which is very wonderful.
The first change is color. Some children like to wear shoes of all colors, but it is impossible to buy all colors! To this end, parents and children are very worried. But with this? Three shoes? Don't worry, just press the yellow button and the children can choose their favorite color, because there are 48 colors for you to choose from!
The second change is shoes? Size? It can be adjusted at will. What worries mothers most is that the child 10 is about 0 years old, and his feet are getting longer every day. The shoes they just bought still have a big finger. Who knows that after two or three months, my feet will be squeezed and a pair of good shoes will be thrown away. Parents spend a lot of money on this. Now just press the red button. Three shoes? Immediately increase the size and lengthen it to fit your feet, so that you can wear shoes that fit you every day.
There is also a green button on the shoe, which is an accelerator to speed up walking. If you are going to be late for school, press it. Three shoes? Start the throttle immediately, and your feet will immediately speed up the frequency and increase the stride. In a blink of an eye, you have come to school, and you don't have to worry about being late for school anymore.
Three shoes? Good, but what if the child plays a prank and presses the button? It's okay. I thought of it a long time ago. Three shoes? It has fingerprint recognition function, and it only listens to the owner's instructions.
How's it going? Mine? Three shoes? Cool enough! At present, it's just my daydream, and it hasn't come true yet, but as long as I look for my goal and go all out, it will definitely come true. Then let's try it!
My invention, grade four, composition four
Last May, my parents took me to Taigong Lake. I saw a garbage mountain by the roadside: white plastic bags were blown all over the sky by the wind. The bag is full of air, white and fat, and the air smells bad. That's disgusting. I quickly covered my nose and said to my parents. Let's go, it stinks in here.
I have seen this scene countless times in the trash can in the classroom and near the trash can in the living area. I think there is too much garbage in life, which is very harmful and pollutes the environment. After burning, they become toxic gases, endangering nature and human beings.
I hope there will never be rubbish on the earth. I want to invent a trash can. This trash can is amazing and simple in structure. Its surface is the same as that of an ordinary trash can, except that there are three more buttons, which are red, yellow and green. When we throw waste paper in, just press the red button and new white paper will come out from the outlet of the trash can. At the same time, it will bind paper according to our needs. You can even put plaids and pleasing patterns on it. The yellow button is mainly responsible for sewage treatment. China's water resources are decreasing. Sewage can be recycled after being treated by trash can, which can effectively save water. The green button has the function of purifying air, which can remove the odor in garbage and turn carbon dioxide into fresh air.
