“…Kasper and Rose (2002) summarized five stages of L2 request development in L2 environments based on findings from the longitudinal studies by Achiba (2002) and Ellis (1992): (1) pre-basic (highly context-dependent), (2) formulaic (unanalyzed formulas), (3) unpacking (shifting to conventional indirectness), (4) pragmatic expansion (adding new forms), and (5) fine tuning (of request force and context). This proposed developmental pattern of L2 request production is supported by crosssectional studies (Hill, 1997;Rose, 2000;Trosborg, 1995) as well as longitudinal studies of other speech acts (Ren, 2013a) and can be generalized to foreign language environments and L2s other than English (Greek in Bella, 2014;Spanish in F elix-Brasdefer, 2007; Indonesian in Hassall, 2003;and Chinese in Wen, 2014). However, learners in foreign language environments tend to show less sociopragmatic development than those in L2 environments (Hill, 1997;Ren, 2013b;Rose, 2000;Scarcella, 1979;Trosborg, 1995).…”
