ABSTRACT Appraisal Theory was developed in recent years, which places emphasis on the interpersonal metafunction in Systemic Functional Linguistics and discloses the stance of speakers and writers, or even that of translators. This thesis uses the Appraisal Theory as a tool to investigate the attitude and positioning of the speakers -- here referring to the translators of two editorials chosen from New York Times and 环球时报 (Global Times). The Source Text (ST) and the Target Text (TT) will be described in the appraisal theoretical framework and then compared to reveal the differences in terms of the speaker's positioning in the ST and TT. After the comparison, the results obtained from the two news agencies too. Lastly, some discussion would be made concerning possible reasons behind the fact of the changed positioning from the ST to the TT, The results would lay out some possible reasons why there are changes between the ST and the TT.
