It is featured with prompt, unpredictable and comprehensive characters. Based on the analysis of interpretation behavior, this paper focuses on the theoretical basis of SL effect from the perspective of communication, contrastive linguistics and socio-linguistics. In addition, the author discusses the countermeasure of SL effect. It is concluded that interpretaters can not only take the countermeasure of adaptation, but also make a reasonable expla-nation and induction of the domain language to complete the task of interpretation promptly, honestly and exactly.
