Key sentence意思

"Key sentence" is a term used in writing and communication to refer to a sentence that is particularly important, central, or critical to the meaning or purpose of a text or message. It is often the sentence that encapsulates the main idea or argument of the piece, and as such, it is typically the sentence that the author wants the reader to remember or take away as the most significant.

In legal documents, academic papers, and formal communications, key sentences are often highlighted or emphasized to make their importance clear. In other contexts, such as in journalism or marketing, the key sentence might be the opening sentence of an article or advertisement, designed to grab the reader's attention and convey the main point right away.

When analyzing a text, identifying the key sentence can be a useful strategy for understanding the author's intent or the central theme of the work.
