It is found that before the experiment, there are macro and micro differences in the engagement resource density between the experimental class's and the native English writers' articles, but after the experiment, these differences no longer exist, and the diachronic comparison of the experimental class's articles shows that this writing teaching mode has high effectiveness of promoting learning. This study can introduce a new method into the teaching of English argumentative writing, enable Chinese English learners to grasp the authentic English writing patterns, and contribute to the promotion of second language writing research.
