How to write the 550-word composition "changeable weather" in grade four?

It's really hot! Cicadas are returned to singing in the trees, dogs are still sticking out their tongues with their mouths open, and people haven't put on new coats yet. However, this autumn is not as cool as before. The earth burns slowly like a volcano, and the sun shines on the earth with the warmest enthusiasm, as if sunspots jumped out of the sun. People don't want to come out, and children play outside, just like being fished out of the water.

Another day. As soon as I walked out of the house, I found it was very cold outside. I added another coat and looked outside. "ah! Why do so many people wear coats and trousers? " "oh! Right, right! Cold! " This time, the puppy also took back its tongue, and everyone stopped turning on the air conditioner, as if mother-in-law Bing had come to the world. It was crisp in autumn at first. Suddenly, the dark clouds are like a black silk scarf, pressing down bit by bit ... Preschool children flee in fear, some hide in the classroom, and some scream on the playground. Then, father-in-law Lei and his electric mother-in-law cried in despair, and the whole city was stuffy in the "black silk scarf cloud".

This morning, although it was very hot, it was breezy and sometimes I felt a little cold. But in the afternoon, the burning sun shone on the earth again, and many students sweated on the physical education class. I heard that some students are ill.

Now, the relationship between weather and environment is getting closer and closer. I still remember the disaster that Typhoon Lee Tae brought to my hometown last year. We must protect the environment so that the country and people can be safe.
