In 2022, I am already a great scientist, I can invent a lot of new things. Diary winter vacation diary 0s net.Cn
I saw today is a rainy day, pedestrians on the road holding umbrellas walking in the rain street, looking at the rain drop by drop, I looked at the rain and thought: in rainy days, we should hold umbrellas to avoid the rain, so everyone should take umbrellas to the side at any time, which is very troublesome. If there is a fully automatic umbrella, then people will not forget to bring umbrellas.
I'll come to my lab and invent. A few hours later, my invention was done.
This is a 'fully automatic umbrella'. This umbrella has three functions. Let me introduce it to you. First, it has lighting function. It can light for you at night. This light can save energy and reduce emissions, and can also light. It has the best of both worlds.
Second: it can predict when it will rain. Just like the weather forecast, it tells you the weather.
Third: when it rains, it can open the umbrella automatically. Even if you don't have an umbrella, it doesn't matter. As long as you call 'my umbrella', it will fly to your side to protect you from the rain.
This is the future umbrella I invented. Do you like it?
