Abstract: Metadiscourse plays a vital role in both English news reporting and commentary, which makes news reporting more coherent and fluent and at the same time helps news commentary writers to better project themselves into their writing and build a good relationship with their readers to make their voices more acceptable and persuasive. This paper is based on a corpus of metadiscourse in 30 English news reportings and 30 news commentaries to explore the similarities and differences of the use of metadiscourse in them. It is hoped to shed some lights on the practical research on metadiscourse as well as the reading,writing and translation of English news.
