英语翻译
When we came home,Aunt Sylvie would certainly be home,too,enjoying the evening,for so she described her habbit of sitting in the dark.Evening was her special time of day.She gave the word three syllables,and indeed I think she liked it so well for its tendency to smooth,to soften.She seemed to dislike the disequilibrium of counterpoising a roomful of light against a worldful of darkness.Sylvie in a house was more or less like a mermaid in a ship's cabin.She preferred it sunk in the very element it was meant to exclude.
