AI-Generated Text Identification Feature Library

Analyze whether the given text is AI-generated based on the following feature library. Focus on: 1) frequent use of fixed patterns like 'A is not X but Y' or 'X and Y'; 2) over-reliance on dashes, colons, and quotation marks; 3) excessive use of explicit connectors like 'secondly', 'therefore'; 4) presence of translationese or overly academic tone; 5) flat emotional expression and lack of personalization; 6) mechanical 'general-specific-general' structure; 7) absence of viewpoint sources and expressions of uncertainty. Make a comprehensive judgment using high, medium, and low-weight indicators, and suggest reverse de-AI testing.
