The Tale of the Clownfish and the Great Shark (this title has been free for a long time)
http://www.amazon.com/Clownfish-Great-Shark-Rhyming-Childrens-ebook/dp/B008ZUQJDY/
The author, Lily Lexington, used rhythm and rhyme to write an interesting story. The beautiful pictures make the book even better. Here is the correct way to say the words on each page: nouns, verbs, adjectives and adverbs are usually louder than other less important words (the, and, in etc.).
韻文的正確念法:每一行有四個重音(虛字,如限定詞、連詞、介詞等等都不算拍子)而最後一個字押韻,讀起來很好聽哦!
Under the bubbles and down in the deep
creatures reside with the secrets they keep
One of the fish is the scariest of all
The Great White Shark is what he is called
