Phrasing does not sound natural. The patterns may create a singsong rhythm, or a chop-chop cadence that lulls the reader to sleep. Although sentences may not seem artfully crafted or musical, they get the job done in a routine fashion. Sentences are constructed in a way that underscores and enhances the meaning. Even if the piece is flawlessly edited, the sentences would not hang together.
Sentences vary in length as well as structure.
Fragments, if used, add style. Dialogue, if present, sounds natural. Purposeful and varied sentence beginnings add variety and energy. The use of creative and appropriate connectives between sentences and thoughts show how each relates to and builds upon the one before it. The text does not invite expressive oral reading.
