At the beginning, the thesis offered an analysis on the backgrounds of Unit Integral English Teaching Approach, the reasons for choosing the research topic and its theoretical and practical significance. Through literature review and summary, the origin of Unit Integral English Teaching Approach, its basic conception and present achievements home and abroad were discussed. Then the theoretical support of Unit Integral English Teaching Approach, System Theory, was introduced and its basic axioms and principles were summarized. Upon this base, the experimental framework was put forward and the exemplification of the study was described in details.
