Contrary to abbreviation, expansion is to add branches and leaves to the trunk, that is to say, 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.
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.
Extended data:
Write sentences in the form of answering questions according to the content of the article. This kind of reading will appear in the reading questions inside and outside the class. You should read the original text and find the words that match the original content to expand the sentence.
For example, "Edison discovered the filament." What filament is it?
According to the text, this sentence can be extended to: "Edison discovered a cheap and durable filament." When doing this kind of sentence expansion, we must first figure out what questions need to be answered and how to answer them. Answering questions must be accurate and consistent with original intention. Secondly, we must find the location of expansion.
