"This book is a must read for students of bilingual first language acquisition. In this groundbreaking work, Ruying Qi traces the development of two of the world's most important languages, Mandarin Chinese and English, in a young child of immigrant parents growing up in Australia. Dr. Qi's work is trendsetting in its focus on pragmatic and semantic aspects of the bilingual development process, which have been understudied phenomena so far. Bilingualism and child language scholars alike will appreciate the many bridges made between issues specific to the bilingual situation and theoretical issues relevant to the study of child language in general." - Professor Annick De Houwer, University of Erfurt, and Director, European Research Network for Bilingual Studies ERBIS Germany
