Want to quickly determine if a piece of text is AI-generated? You can often tell just by the sentence structure.

Chinese AI features are very obvious: "This is not xxx, but yyy." Such expressions appear frequently. Once you see this kind of comparative sentence stacking up, it's highly likely to be the work of a large model.

The same applies in English: "that's not xxx. That's yyy." This stiff binary opposition expression is like the LLM has been programmed into the system, recurring repeatedly.

Why is this the case? Because the language models learn and optimize their expression patterns during training. These sentence structures appear frequently in the dataset, so they naturally become default templates during generation. To identify AI writing, just catch these "tics" (repetitive habitual actions). Next time you encounter suspicious content, check for these signs.
