Analysis: amplification writing is to add branches and leaves to the trunk, that is, to add joint elements such as attributes, adverbials and complements according to the needs of expression, so as to make the meaning of a sentence or text more specific and full.

Matters needing attention when zooming in:

When expanding, we should add effective components reasonably according to the needs of expression, and do not pile up words with the same meaning, repeat them before and after, and do not change the meaning of the original sentence.

When completing the expansion homework or test questions, if there are specific provisions on the expansion part, it should be expanded according to the regulations. If there is no regulation, it can be expanded as a whole. Don't forget to punctuate the extension.
