چکیده:
Lexical bundles are known as important elements of coherent discourse that have been the subject of much research. While the previous research has been mainly concerned with exploring variations in the use of these word sequences across different registers and disciplines, very few studies have addressed the use of some particular groups of lexical bundles within some types of academic writing. To probe in to the possible generic variations, this research focused on anticipatory it bundles as a particular structural group of these word sequences. More specifically, this study chose to investigate range, frequency, and function of these word clusters in applied linguistics published and unpublished writings. Through the use of two big corpora and text analysis programs, this study found that it bundles were used relatively frequently in both published and unpublished writings. Functional analysis also showed that it bundles served a wide variety of functions in both types of writings. Notwithstanding these findings, this study also revealed that some it bundles commonly used in unpublished writing did not count as bundles in published writing.

While the previous research has been mainly concerned with exploring variations in the use of these word sequences across different registers and disciplines, very few studies have addressed the use of some particular groups of lexical bundles within some types of academic writing.
Since 1999, a number of studies have been specifically launched to explore possible differences and\or similarities in the use of bundles between a few disciplinary fields (Cortes, 2002, 2004; Hyland, 2008a, 2008b), registers, such as conversation, fiction, news, academic prose, classroom teaching and non- conversational speech (Biber et al.
More specifically, the study probed the use of it bundles in two groups of applied linguistics academic writing: research articles, representing published writing, and postgraduate theses, as written by students at master’s and doctoral levels, reflecting unpublished writing.
Accordingly, two corpora of published and unpublished writings in applied linguistics were used in this study to find whether these two types of writing in one single disciplinary area are similar or different from each other in terms of their use of it bundles.
