Abstract The present study compared 4-word lexical bundles found in a general engineering corpus (2,030,000 words) with those found in a corpus of texts collected from a Pathway engineering course for ESL (English as a Second Language) students (356,000 words) and a corpus of pedagogical materials used to teach advanced ESL students at an intensive English program (440,000 words). The results indicated that the structural and functional characteristics of the lexical bundles in the Pathway engineering materials were representative of the discourse features found in the general engineering corpus. This finding provides additional evidence of the overall appropriateness of the pedagogical materials selected for the Pathway course. Furthermore, the two engineering corpora also included a substantial number of bundles that were unique to the specific course materials, and, therefore, can potentially be targeted during language instruction.

摘要 本研究将通用工程语料库（2,030,000 字）中的 4 字词组与 ESL（英语作为第二语言）学生的 Pathway 工程课程（356,000 字）和用于在强化英语课程中教授高级 ESL 学生的教学材料（440,000 字）。结果表明，Pathway工程材料中词束的结构和功能特征代表了通用工程语料中的话语特征。这一发现提供了额外的证据，证明为衔接课程选择的教学材料的整体适当性。此外，
