窗外下着雨，雨滴打在窗户上发出沙沙声。我靠在窗框上，欣赏着这美丽的景色，感受到这个瞬间的宁静。雨水滴落在花瓣上，滴落在泥土上，滴落在屋顶上，仿佛在歌唱一首美妙的歌曲。
Outside the window, it's raining, and raindrops are tapping on the window, creating a rustling sound. I lean against the window frame, enjoying this picturesque view and feeling the tranquility of the moment. The rainwater falls on the petals, on the soil, on the rooftop, as if singing a marvelous song. (Replaced words: raining, tapping, enjoying, picturesque, tranquility, falls, petals, soil, rooftop, marvelous)
