Second Language Phrases Acquisition: A Corpus-Based Survey/ Acquisition des Expressions de la Seconde Langue: Enquete Basee Sur Le Corpus‪.‬

1. INTRODUCTION With the research of first language vocabulary acquisition, second language vocabulary acquisition research has emerged since the 1970s. From 1980s to 1990s, many scholars such as Linnaud (1986), McKeow&Curtis (1987), Nation (1990), Nattinger&DeCarrico (1992), Coady & Huckin (1997) published some books specializing in this area (Song, 2002). Recently, some Chinese scholars (Dai, 2000; Lian, 2001; Song, 2002; Liu, 2002) have also made similar research. Among them, Nattinger & DeCarrico(1992), Lian (2001) focused their research on phrases acquisition, that is, the function of lexical phrases and its application in language teaching and learning. This created a new research area to second language vocabulary acquisition.
