In order to avoid boring your readers to death, vary
your sentence structure.
Undesirable: Her
husband does not allow her to work. He does not allow her to take
care of her baby. She longs to do something other than rest. Everyone
says she is sick and must relax. She is trapped in her room. Eventually
she begins to go mad.
Better: Because
of her purported sickness, everyone, including her husband, insists
she must rest instead of working or taking care of her baby. Trapped
in her room, she begins to go mad.
By varying your sentence structure, you not only keep
things lively, you indicate to your readers which assertions are
most important. They’ll instinctively understand that subordinated
details (trapped in her room) aren’t as crucial
as prominent points (she begins to go mad), and
they’ll have a much easier time understanding your writing.
