Exercise 50

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 fi rst thought and a capital letter at the start of the next thought.
