To rearrange the sentence 'The swan-shaped boat was paddled by Jackson Stewart across the pond' to emphasize the action done to the subject without altering its meaning or tense, we should place the recipient of the action at the beginning of the sentence. This sentence is currently in the passive voice, and to shift the focus on the action, it needs to be rewritten in the active voice. Additionally, the sentence could be made more concise and engaging.
The revised sentence would be: Jackson Stewart paddled the swan-shaped boat across the pond. Here, 'Jackson Stewart' becomes the subject doing the action, 'paddled' is the action, and 'the swan-shaped boat' is the object that the action is being done to. Emphasizing the action in this way makes the sentence more immediate and clearer to the reader.
In literary writing, as exemplified by the given prose excerpts, rearranging words and sentences is a tool authors use to create rhythm, emphasis, and narrative structure.
