How does the structure of a piece of work contribute to suspense?

Narrative structure can contribute to suspense in a lot of
different ways--from the line level to the overarching plot
level.

Shorter sentences tend to convey more tension,
resulting in higher suspense.  Using active voice (instead of passive) and powerful
verbs can propel the reader forward.  Examples:

-He was hit
by the man. (Passive voice and weak verb)

-The man punched
him.  (Active voice, more powerful verb)

Ending each
chapter on a cliffhanger can also help promote suspense.  Leave the reader with
intriguing, unanswered questions dangling at each chapter ending and they will be eager
to keep flipping the pages.

In the overall plot, suspense
is best created by withholding information and tension resolution.  For a romantic plot,
the writer maximizes suspense by keeping the two romantic leads apart until the climax.
 In a mystery, the true solution is kept from the reader until the very last moment.
 Ultimately, it's the unknown that keeps the reader in
suspense.

Finally, a good twist near the middle of the book
is a great narrative tool for suspense.  By subverting the readers' expectations with a
sudden twist, the writer can keep the audience engaged and
guessing.
