摘要：The paper describes the text linguistic research of political texts in the field of Translation Studies and presents an overview of critical discourse analysis-based studies.First,the relationship between text,power and ideology and its implications on the role of translation are explored.This is followed by a review of a number of studies on the translation of political texts and on the power relations involved.The paper classifies such studies into the following six categories representing distinct research fields: translators' professional roles and politics;translators acting as mediators in situations of political conflict;translators' professional responsibilities and the strategies they apply;the inference of translators' own historical,social and cultural backgrounds;manipulation in the translation of literary texts and other text types;and critical discourse awareness in Translation Studies.The most recent studies in the above research fields and their results are also presented.It is concluded that these approaches exhibit quite varied research methods and their results are almost impossible to compare.With a view to the future development of this research field,it seems expedient to introduce a unified research theory,method and tool.
