A Study of Lexical Chunks Based on Linguistic and Medical Dissertation Corpora

摘要

Lexical chunks abound in the academic domain. For language learners, the effective storage and proper use of lexical chunks are a prerequisite for improving language cognitive ability and expressive ability. The use of lexical chunks in authoritative academic journals should be regarded as an example of the use of lexical chunks. This study is based on the use of linguistic and medical dissertation corpora to compare linguistics and medical academic English lexical chunks, and analyze its similarities and differences in lexical structure fixation, structural form and discourse function in order to reveal the usage pattern of academic lexical chunks.
