Newspaper Articles can be found in well the newspaper, or some other journal/magazine. The styles are all similar whatever the story due to the skinny columns and small fonts. The story is typically short and to the point. Space is scarce and the quicker the story is told, the better.
Letters are easily distinguishable because they are always addressed to someone. Like starting off with Dear Mr./Mrs. Jones, etc. and ending with a Sincerely, From or some other send off.
Haiku's and poems are special in their own way because haiku's are very short and normally only have three lines which have a specific number of syllables in each, and match other lines in the small poem. Poems also have special rules such as how many syllables are in each line, how many phrases and verses there are and different rhythm schemes. Both of these works of writing are visionary tales, which most of the time tell a story to the reader. Pictures are often added to the haiku's and poems to help tell the story. Here are examples of both a haiku and a poem.
There are hundreds of different documents made each day. It is very important to have a good idea of what your task is and how it should be presented. If unsure, talk with coworkers or peers, find an example template and work off of that. Whatever you can do to properly present your work DO! Not only in school is your written works important, it's even MORE crucial in the workplace to produce correct documentation so good writing and good luck bloggers!
