English Skills 10th Edition by John Langan, Zoe Albright

تمرين 45

Locate the split in each of the following run-ons. Each is a fused sentence -that is, each consists of two sentences that are fused, or joined together, with no punctuation between them. Reading each fused sentence aloud will help you "hear" where a major break or split in the thought occurs. At such a point, your voice will probably drop and pause.
Correct the run-on by putting a period at the end of the first thought and a capital letter at the start of the next thought.
EXAMPLE
Martha Grencher shuffled around the apartment in her slippers. Her husband couldn't stand their slapping sound on the floor.
A felt-tip pen is easy to ruin just leave it lying around without its cap.
