переведите текст,срочно надо((( The real attraction for Jo was a large library of fine books , thought there were dust and spiders there since Uncle March died . Jo remembered the kind old gentleman , who used to let her build roads and bridges with his big dictionaries , and tell her stories about the pictures in his Latin book . The large room , with the tall book-cases , in which she could wander where she liked , made the library attractive to her . the moment Aunt March was busy with company Jo hurried to the library , and read poetry , romance , history , travels , and pictures , like a book-worm . She enjoyed reading her favourite Ivanhoe by W.Scott and Hamlet by W.Shakespeare in this quiet place . But , like all happiness , it did not last long:for as sure as she had just reached the midlle of the story , or the most dangerous adventure of her traveller , her aunt called , "Josy-phine!Josy-phine!" and she had to leave her paradice to help her aunt about the house, wash the dog , or read Belsham's Essays aloud . Jo's ambition was to do something outstanding;what it was she had no idea."I want to do something splendid, heroic or wonderful,that won't be forgotten after I'm dead.I don't know what,but I'm on the watch for it, and mean to surprise you all some day. I think I shall write books , and get rich and famous",said Jo when she was asked about her favourite dream.
