In a faraway land named Bookville,there was a library.But it was not a 1 library,it was a floating (浮动的) library. Many people came to the library on boats.At night,a little mouse named Sam came out and took 2 from the librarians' desk,and took it into his hole.He wrote books for his whole life,but he had 3 shown them to anyone.
