Evidentiality strategy（ES） refers to the use of lexical evidential markers for the purpose of indicating the source of knowledge and the degree of certainty about the proposition expressed. The analysis of the influence, the manner of influence and the degree of influence of ES on English Academic Book Review （EABR） may provide methodological support for the applied research of evidential theory.
