有声读物: Little Susy's Little Servants

“As Little Susy had a kind mamma to take care of her, you will, perhaps, wonder why God gave her also, a great many servants of her own. He gave her so many, that you might spend your whole life in reading about them. But I shall tell you of only a very few, and then you can ask your mamma to talk to you about the others. For the little servants Susy had, you have, too.” - from the first chapter
