The composition "Me Twenty Years Later" in the third grade of primary school is about 300 words.

Time flies. Twenty years later, I became a scientist. I use my invention to benefit mankind and repay my motherland.

I invented a kind of magical clothes that people can only wear all year round. He has three buttons that can automatically adjust the temperature; Winter can keep you warm, and summer can bring you coolness. One of the buttons can change the color and pattern of changing clothes, so people don't have to worry about buying clothes. Another feature of it is that it can be cleaned automatically without handwriting, which can save a lot of water. As soon as this kind of clothes came on the market, it was very popular with people.

I also invented a fully automatic robot. If you want to shop, you only need to input the product name into the robot's computer, and it can go to the mall to buy things according to the owner's wishes, saving time and effort.

At present, human beings have seriously damaged the environment, and the land has the trend of desertification. I have developed a seed with strong vitality, which can take root and sprout as soon as it falls to the ground. But it doesn't need watering. Before long, the seeds I invented can turn all desertification into oases.

In order to realize my ideal, I study hard now and will become a real scientist when I grow up. I want to make people's lives easier and make the earth full of vitality.
