Abstract:	The rapid proliferation of Large Language Models (LLMs), exemplified by AI-assisted writing tools, is reshaping the academic landscape. This study conducts an in-depth comparative analysis of Academic Vocabulary (AV) use between two corpora: Self-composed essays by 30 English-major students (Corpus A) and equivalent essays generated or edited with AI assistance (Corpus B). Employing corpus analysis methods (based on the AWL and lexical diversity metrics) combined with pragmatic analysis, the quantitative findings confirm that Corpus B exhibited a significantly higher frequency and complexity of AV ($p<0.01$) compared to Corpus A, suggesting that AI acts as an effective vocabulary amplifier. However, the qualitative analysis identified three core weaknesses in Corpus B: Collocation Errors; Contextual Inappropriacy, leading to a pseudo-voice; and Lack of Nuance. These findings not only caution against the risk of reduced cognitive engagement among learners but also hold profound implications for Applied Linguistics. The study emphasizes the necessity of shifting the teaching focus from generating complex vocabulary to critically evaluating and refining AI output, aiming to develop students' pragmatic evaluation competence.
