College Writing Skills with Readings 8th Edition by John Langan

Exercise 10

In the following run-ons, locate the point at which one complete thought ends and another begins. Each is a fused sentence: two sentences joined with no punctuation. Reading a sentence aloud helps you hear where the break is. At this point, your voice may drop and pause. Correct each run-on by putting a period at the end of the first thought and a capital letter at the start of the next.
