Summary of the main points of imitation:

1. Try to change from "image" to "image". Similarity: the same or similar in structure, rhetoric and related words. Spirit likeness: context fit, elegant style, healthy thinking, encouraging innovation.

2. Give the imitated sentence "physical examination". See if the choice is wrong and whether it is consistent with the original content, sentence pattern and rhetoric. Whether it can be related to the original meaning, context and integration.

3. The language style should be elegant. The answers to parody sentences are rich and colorful, but if students are not correct in reviewing the questions, they will show negative and pessimistic emotions and have a tired attitude towards life. Show pessimistic thoughts and reflect the lack of human nature.
