摘要:The dissertation focuses on the classroom linguistic environment for SLA. The
discussion on the view that interaction is an effective way of creating an optimal linguistic environment
for SLA in class by providing prehensible input will be presented from a stage of theory to its
application. First, the dissertation will demonstrate three important theories: the input hypothesis, the
interaction hypothesis and the output hypothesis, and their relationships as well. Then is the discussion
on the functions of classroom interaction and its application in English classes. The point throughout
the dissertation is that classroom interaction offers a stage, on which prehensible input and the
comprehensible output, the two indispensable elements of the linguistic environment, co-operating
perform effectively for SLA.
