【概括大意】I love sunny days because they are ideal for outings. I remember the sunny weekend when two roommates and I had a marvelous time in the old Summer Palace.

I watch the rain washing the trees and grass clean, knowing they will glitter when it clears up and hoping a rainbow will follow. In winter, a heavy snowfall offers a different type of pleasure. Cold as it often is, I always go outdoors and leave my footprints in the thick snow while throwing snowballs and making snowmen with my fellow students.
