The Pragmatic Functions of I think in Different Genres

The present paper aims to examine the occurrence of I think in different genres. A collected data of I think from graduate student research interview and objectivism group study within Michigan Corpus of Academic Spoken English (MICASE) is analyzed. Both quantitative and qualitative analyses are included and the selection tool Antconc 3.4.4 are adopted in the study. By using concordance, all the context including I think are collected. Meanwhile, some phrases (such as I think so, what I think, I think of, etc.) are deleted from the analysis. It is found that I think in different positions and with different collocations fulfill different pragmatic functions respectively. The phrase I think is very frequent in GSRI and OSG, which is due to the nature of the discourse, where the participants are engaged in the communication. From the perspective of syntax and collocation, a lot of examples are analyzed in details. It is found that the interpretation of I think cannot be reached without exploring its linguistic context. In addition, a more detailed observation of linguistic context of I think in OSG and GSRI is explored. Some epistemic certainty (certainly, really, etc.) are included in research interview, with the function of emphasis and deliberation. The study might help to reconsider the functions of I think in different genres.
