I like rainy days. Here are some of the reasons (理由).
I think that rain can make the air cool off. No matter (无论) how hot it is,it gets cooler when it rains. I like opening my windows to let the cooler air in.
I like the smell in the air when it begins to rain. It's a kind of clean and fresh smell.
I like the sound (声音) of rain when it hits things. I like closing my eyes and listening to the rain coming down,and I like hearing different sounds of rain.
I like rainy days,because they give me an excuse (借口) to stay in and be lazy. That is one of the best things in my daily life. And reading a good book on a rainy day is one of my favorite things.
Another reason is that it makes the grass green and helps the trees and flowers grow.
