To improve the taste of an insipid factual statement, baste in metaphor, bake with active verbs, and serve soused in piquant words. But be wary of overdoing it.
For example: There was a mirage on the horizon.
Could be changed to: Sun-drunk air shimmered in the offing.
Regardless of whether the edit is an improvement, it is a more complex piece of writing which triggers a more complex response. In particular, the reader recognises the sentence as not being literal because air cannot be drunk.
