Show Answer Key & Explanations Step-by-step solution for: Run on and Fragments | Sentence Structure Worksheets
The task is to fix run-on sentences and sentence fragments by rewriting each so that it becomes a complete, correct sentence.

Let’s go through each one:

1. “The boy on the phone” → This is a fragment — it doesn’t have a verb or tell us what happened.
Fix: Add an action. Example: “The boy was talking on the phone.”

2. “We count sheep to sleep don’t you?” → This is a run-on — two thoughts smashed together without proper punctuation.
Fix: Break into two sentences or add punctuation. Example: “We count sheep to fall asleep. Don’t you?”

3. “Don’t run in the house it’s too dangerous.” → Run-on — two independent clauses joined incorrectly.
Fix: Add period or conjunction. Example: “Don’t run in the house. It’s too dangerous.”

4. “Ran to the bakery.” → Fragment — no subject. Who ran?
Fix: Add a subject. Example: “She ran to the bakery.”

5. “I wrote a letter it didn’t get there.” → Run-on — two complete ideas stuck together.
Fix: Add punctuation or connector. Example: “I wrote a letter, but it didn’t get there.”

6. “When she sang, the pretty girl in the choir” → Fragment — starts with “when” but never finishes the thought.
Fix: Complete the sentence. Example: “When she sang, the pretty girl in the choir smiled.”

7. “Blew off the tree because of the wind” → Fragment — who or what blew off? No subject.
Fix: Add subject. Example: “The leaf blew off the tree because of the wind.”

8. “The children on the ride screamed loudly they hurt my ears.” → Run-on — two full sentences mashed together.
Fix: Add punctuation or break up. Example: “The children on the ride screamed loudly. They hurt my ears.”

Now, here are the corrected versions as final answers:

Final Answer:
1. The boy was talking on the phone.
2. We count sheep to fall asleep. Don’t you?
3. Don’t run in the house. It’s too dangerous.
4. She ran to the bakery.
5. I wrote a letter, but it didn’t get there.
6. When she sang, the pretty girl in the choir smiled.
7. The leaf blew off the tree because of the wind.
8. The children on the ride screamed loudly. They hurt my ears.
