Complete Sentences and Fragments

Write complete sentences and fix fragments.

A complete sentence has a subject and a verb and makes sense on its own: “The bell rang.”

A fragment is part of a sentence pretending to be a whole one. “Because it was cold.” and “The old lighthouse on the hill.” are fragments: one has no main clause, the other has no verb.

Fix a fragment by joining it to a main clause (“We wore hats because it was cold.”) or by adding the missing subject or verb (“The old lighthouse stood on the hill.”).

Worked example

Fix the fragment: “When the rain stopped.”

  1. It begins with when, so it needs a main clause.
  2. Add what happened: we went outside.

Answer:When the rain stopped, we went outside.
