Step-by-step solution for: Comma Worksheet for Punctuation Practice
Here’s the corrected version of Worksheet #3: The Comma, with commas added where needed. I’ll explain each correction so you understand the grammar rules.
---
1. Tom, my uncle, has found bats in his attic.
→ *Explanation:* “My uncle” is an appositive — it renames or clarifies “Tom.” Appositives are set off by commas on both sides.
2. New York, where I live, is an amazing city!
→ *Explanation:* “where I live” is a nonrestrictive clause (it adds extra info but isn’t essential to the meaning). Nonrestrictive clauses are surrounded by commas.
3. If you weren’t so grumpy, I’d play with you.
→ *Explanation:* When a conditional clause (“If you weren’t so grumpy”) comes before the main clause, use a comma after it.
4. Bats are nocturnal, which means they sleep during the day.
→ *Explanation:* “which means…” is a nonrestrictive relative clause — it gives extra info about “nocturnal.” Use a comma before “which.”
5. If you don’t behave, you won’t be going to the park.
→ *Explanation:* Again, introductory conditional clause → comma after it.
6. Without water, flowers can’t grow.
→ *Explanation:* “Without water” is an introductory phrase. Introductory phrases often need a comma before the main clause.
7. Cumulus, status, cirrus, and nimbus are all types of clouds.
→ *Explanation:* This is a list of four items → use commas between each item, and a comma before “and” (Oxford comma).
8. Lizards, snakes, turtles, and crocodiles are all reptiles.
→ *Explanation:* Same as above — list of 4 items → commas between, including before “and.”
9. Enemies of the zebra include hyenas, wild dogs, and lions.
→ *Explanation:* List of 3 enemies → commas between, including before “and.”
10. Remember, we’re not having indoor recess today.
→ *Explanation:* “Remember” is an introductory word used to address the reader → comma after it.
11. If I had a watch, I would never be late again.
→ *Explanation:* Conditional clause first → comma after it.
12. Jake, my friend, had his tooth pulled out today.
→ *Explanation:* “my friend” is an appositive renaming “Jake” → set off with commas.
13. Jake said, “Getting my tooth pulled out didn’t even hurt.”
→ *Explanation:* When quoting direct speech, use a comma before the opening quotation mark if the quote follows a reporting verb like “said.”
14. Peaches, pears, apples, and oranges are my favorite fruits.
→ *Explanation:* List of 4 fruits → commas between each, including before “and.”
15. At my party, we all sang silly songs.
→ *Explanation:* “At my party” is an introductory prepositional phrase → comma after it.
