Somehow, the weather in our Wuhan area is always unpredictable.

On this day, I watched TV at home. Blue sky, bright rainbow and Wan Li, the sun shines brightly on my face through the window. I naturally feel relaxed and happy. Watching TV at this time is really a pleasure! It didn't take long for the glory to disappear. Followed by dark clouds and strong winds. Dark clouds seem to be thick layer by layer. As thick as a cotton ball. It has been dangling in front of my eyes.

Suddenly, the sky opened a string of red light, like scissors falling from the sky. Boom, boom! Followed by two loud noises. It thundered! I've always been as timid as a mouse. Cover your ears quickly. There was a heart-rending roar in the dark clouds. There seems to be a fierce dragon growling. How scary! My legs are shaking.

But God seems to be joking with me again-the clouds have opened, the wind has blown and the thunder has struck, but it just doesn't rain. This makes me very angry. After a while, the dark clouds cleared a lot. I walked out of the garden and was about to go shopping. But damn it, it's not early, it's late. I ran home in three steps and two steps.

It's raining heavily in the blue world, but it's hard to stop the rain at this time. I can't believe I fell asleep. After a while, I suddenly felt warm, and I slowly opened my eyes. God, the rain only stopped once. At this point, the scorching sun is shining, which makes me "Zhang Er monk-confused". Old innocence can play tricks on people! The weather is like a magician, constantly changing his tricks.

But no matter how clever his tricks are, I can't be blind-when I grow up, I will invent the' advanced meteorological detection satellite' to serve mankind!
