Ray Bradbury's novel "All Summer" is a science fiction work at Venus primary school, and settlers on the earth built underground settlements filled with long tunnels. In these complex facilities they are living their lives and raising their children. Unfortunately, on Venus, the rain is constant. It continues a large shower every day, indefinitely. However, one day, every seven years, the rain stops and the sun can be seen for a short time. According to the confidence of the scientists at least the day the story was opened the sun should be visible. Most of the school's children are nine years old, I have never seen the sun. They are too young to remember that it appeared seven years ago. They grew up in a dark, sunless world. But one of them - a girl named Margo who came recently from the Earth can vaguely recall how the sun appeared when she was there.
Ray Bradbury's "day trip" theme is bullying. It is due to jealousy and jealousy. Interestingly, Ray Bradbury chose to explore this theme in the context of the next generation, and this generation has the opportunity to evolve among planets as a result. Even so, in the imaginary environment of Venus, bullying still exists after hundreds or thousands of years of human evolution. This shows that in Bradbury's view, bullying other poor people has been a deep-seated human being that has existed for centuries. The sub-theme of short stories is nostalgia and longing, Margot and her classmates have illustrated this.
