Step-by-step solution for: Separating items with commas | Worsheets library
Let's go through each sentence in the worksheet and fix the punctuation mistakes, specifically focusing on separating items or phrases with commas where needed. We'll use commas to separate items in a series, independent clauses joined by coordinating conjunctions, and interrupting phrases.
---
✔ CORRECT
*Explanation:* The sentence lists three activities: "travel to Colorado", "ski in the mountains", and "drink a lot of chocolate". These are separated correctly with commas. The Oxford comma (before "and") is used appropriately.
---
✘ Needs correction.
Corrected: *That man lost his keys, left them in the yard, and started crying.*
*Explanation:* There are three actions: "lost his keys", "left them in the yard", and "started crying". They should be separated with commas. Also, "left" needs an object ("them") for clarity.
---
✘ Needs correction.
Corrected: *When I woke up, I ate breakfast, brushed my teeth, and packed my lunch.*
*Explanation:* The list of actions after "I" includes three items: "ate breakfast", "brushed my teeth", and "packed my lunch". They must be separated with commas. The missing comma after "breakfast" makes it unclear that these are separate actions.
---
✔ CORRECT
*Explanation:* Three actions: "saw the movie", "went to dinner", and "had a great time" — all properly separated with commas.
---
✘ Needs correction.
Corrected: *We arrived, talked, and left.*
*Explanation:* Three verbs in a series: "arrived", "talked", and "left". They need to be separated by commas.
---
✘ Needs correction.
Corrected: *The teacher asked us to put our backpacks away, to get our homework out, and to start the daily activity.*
*Explanation:* Three infinitive phrases in a series: "to put our backpacks away", "to get our homework out", and "to start the daily activity". Each should be separated with commas.
---
✘ Needs correction.
Corrected: *The dog ran to the park, chased a squirrel, and chewed the leaves.*
*Explanation:* "Chopped" is incorrect here — dogs don't chop leaves. "Chewed" is more appropriate. But even if "chopped" were correct, the sentence structure is fine with commas. However, since "chopped" is not a realistic verb for a dog, this might be a typo. Assuming it's meant to be "chewed", the corrected version is above.
---
✘ Needs correction.
Corrected: *A superhero flies, helps, and saves.*
*Explanation:* Three verbs in a series: "flies", "helps", and "saves". They need to be separated with commas.
---
✘ Needs correction.
Corrected: *Tammy and her husband plan to go to the pet store, get a dog, and bring him home.*
*Explanation:* Three actions in the infinitive phrase: "to go", "to get", "to bring". They need to be separated with commas.
---
✘ Needs correction.
Corrected: *My plan is to finish school, go to college, and become a teacher.*
*Explanation:* "Schoolgo" is a typo — should be "finish school", then "go to college", and "become a teacher". All three are parts of a series of goals, so they need commas.
