Query: Not what I thought

This reader was not what I thought. Not all the reader is written with characters. The sentences and reader combines romanization and characters as well. I would prefer that the new vocubulary, that it is supossed that you do not know, would be first presented in both, romanization and character, and use only the character in the reader.Another thing that I do not like is the Yale romanization used in the book. I think pinyin romanization would be much better.
