Please help me modify the following paragraph, thank you very much! "When I got up this morning, I saw that a heavy rain was falling and the sky was gray. After a short while, the streets of the community literally became a wide river. Many people out on the streets were using umbrellas, while those without one were only wearing their wet clothes. A few even wore slippers! Others wore raincoats, some of which were colorful, if not beautiful. Some children were being carried by adults, some merely had their hand held by one, while some walked by themselves. Everyone had difficulty walking to work, to school, or to wherever they needed to go. Why? The rain had come down in earnest. After the heavy rain ended, the trees were greener, and the air also had a fresh and moist fragrance."
