摘要：The advances in the field of second (L2) and foreign (FL) language teaching and learning in the past two decades have been manifold, among these: acquisition theories that have emerged as a consequence of refinements in experimental and methodological tools; the shift of focus to approaches rather than methods in L2 and FL teaching; socio- interactionist studies’ emphasis on the ecology of the classroom, geared towards community building; and the questioning of teacher training paradigms by teacher development and education programs.
