One day, when I came home from school, I suddenly heard an argument. She approached curiously, hid under the window, and looked into the room, only to see the cars passing by, arguing fiercely. The cyclist groaned: -I am the simplest means of transportation. But I help people. Every child learns to ride a bicycle. Although I am a primitive person, I avoid environmental pollution which is very good for health, even the elderly use me to exercise. Fat people can practice cycling to reduce cn and maintain health. However, people seem to have forgotten my purpose. I seem to be forgotten. When interrupted by the motorbike, the bicycle still said: - Oh! Her era is behind. Nobody rides bikes anymore. Motorbike by now is the best choice. Overlooking the street, mostly motorbikes. People are increasingly improving the model. We become more beautiful, thinner and more practical. Riding a motorbike is very fast and convenient. When the bicycle was interrupted, the motorbike said about its usefulness: - Don't brag about it. You will see how much of your household's emissions are released into the street. The streets are full of gasoline, and the air is polluted partly because of you. Moreover, since having brothers, the silence is broken. Bad youth, thanks to the new brothers organized car racing, more traffic accidents, many people died. The biker severely criticized Uncle Motorcycle. After hearing this, Uncle Motor quickly explained: - Oh! You misunderstood. We invented it to facilitate travel. Bad youth abused us. Woe to us. I think the happiest person is Brother Che. Always respected. The car immediately said: -If you don't understand me, compare with me. I have modernized and just served people's lives. I help people not to work too hard on long journeys. Uncle Che is not as grumpy as his sister on a bicycle or a motorbike. He gently said to them: Why are you fighting like this? We are all transportation, we must love and help each other. Although we come from three different generations, we represent the advancement of society. Each of us has our own responsibilities. Let's unite and help those we can. Sister Cycling and Uncle Mo were embarrassed. They shyly apologized and shook hands. If it weren't for the car, they might have fought. I think the car deserves to be the brother of the family. Aunts and uncles always gently advise and explain to people wrong understanding, thereby living better. I will tell my parents about this tonight.
