Lexical bundles are the continuous phrases framing and shaping thoughts as the building blocks of the discoursal units in rhetorical moves. These bundles are distributed across a variety of academic disciplines. This work aimed to identify lexical bundles in electrical engineering abstracts, to investigate the structures of lexical bundles and to analyze them to the rhetorical moves. The self-compiled corpus called Eng-Corpus was a collection of four prestigious journals in an engineering field the recent years. Using the form-first approach, this study found that 84 bundle types occurred in the corpus. Structurally, most of these lexical bundles were cooperated with noun phrase and prepositional phrase fragments, while those with dependent clause fragments were scarce. For the connection between lexical bundles and move, it was found that some bundles have multiple functions across different moves of abstracts. These findings are drawn to pedagogical use for engineering abstract writing discourse.
