Writing for Style
From The Editorial Eye and Working With Words

Some ideas related to using the best words:

* Keep verbs in active voice (usually).
* Avoid wordiness, redundancy, cliches, jargon and "journalese."
* Use short, simple common words most of the time.
* Use specifics rather than generalizations. Be precise.
* Place modifiers (including adjectives, adverbs, prepositional phrases, participial phrases) as close as possible to the word they modify. 

Some ideas related to making sentences sing:

* Keep sentences short and straightforward, especially leads.
* Use direct quotes to convey feelings rather than facts. Ensure the context of the quote is clear and accurate.  
* Relate the importance of ideas to their placement and use in the sentence.
* Vary sentence length and structure in a story to avoid monotony and create "flow."
* Express similar ideas in a similar (parallel) way.

 

And some general pointers ...

* Anticipate questions that readers might have and answer them.

* Stick to the facts and maintain your neutrality.

* Watch out for stale story approaches, especially to features and to recurring stories (the annual city budget deliberations, the start of the school year...). If you've seen a lead a hundred times, so have your readers.
* Explain unusual of complicated terms, without talking down to your readers.
* Understand basic math! :-)
