Some one in this forum (I can't remember where) recently recommended this website for listening practise http://www.tingbook.com/book/57-2.html
The site looks very promising, seems to have a wide variety of audiobooks on different levels with transcripts.
My Chinese is not good enough though, to figure out if the site is completely free of charge and if it's safe to creat a user-account (neccessary for downloading materials).
For example I just found an Chinese version of the Ugly Duckling.
You can listen to everything online and you can also download, but you have to register for that.
