My little invention is a third-grade composition of 300 words.

On summer nights, annoying mosquitoes always bite people, suck human blood, spread diseases and buzz all the time, which makes people unable to sleep well. I want to invent a special mosquito-killing perfume.

This perfume, made of special materials, can give off a particularly strange fragrance. As long as mosquitoes smell this fragrance, they will immediately lose their attack ability and fertility. Now they can't even suck human blood, let alone breed, and they will infect each other. Over time, mosquitoes will gradually become extinct.

This mosquito killer can not only kill mosquitoes, but also be effective against pests such as flies, cockroaches and bedbugs. But it is harmless to human beings and their friends-poultry, livestock and beneficial insects. Why is this? Because in the process of perfume production, we extracted the genes of the four pests and mastered the "life gate" of the "four pests", so the perfume made is particularly targeted and will definitely become a "super secret weapon" to kill the "four pests" in the future!

Having said that, you may ask, how to make this perfume? Hehe, I can't tell you now, my perfume is in the trial production stage! When I apply for a patent and put it into mass production, you can buy it everywhere.

Everyone has lofty ideals, and if you want to realize them, you should start with small things.

In order to realize my dream, I began to use my brain and make some small inventions. ...

Today, when I was watching TV, I saw some decorations made by some people on TV, and I thought: Can I do better than them? Sure! I can do it well!

At this time, I began to prepare materials. I searched and searched for a long time, and turned my house upside down, only to find a piece of white yarn and some colored threads. Having prepared the tools, I began to make decorations.

First of all, I folded the gauze in half, sewed the other three sides with a needle, found a piece of paper as big as the gauze, drew a picture on the paper with a colored pen, put the paper into the gauze and sewed the gauze. Then, I drew a beautiful picture on the other side of the gauze with a colored pen, and then I sprayed perfume on it. Finally, I tied the numbered one to the gauze and hung a bell under it. In this way, a sachet is ready.

Look! This is my little invention! Does it look nice?
