Step-by-step solution for: Grade 8 - Commas Review worksheet
Here is the corrected version of each sentence with commas added where needed, along with an explanation for each correction:
---
1. Albert, what makes a sneaker comfortable?
✔ Explanation: When directly addressing someone by name (direct address), you must set off the name with a comma. “Albert” is being spoken to, so it needs a comma after it.
---
2. I think support, comfort, and cushioning are three important things.
✔ Explanation: This is a list of three items: “support,” “comfort,” and “cushioning.” In a series of three or more items, you use commas to separate them. The comma before “and” is called the Oxford comma — it’s optional in some styles but recommended here for clarity and consistency.
---
3. Our track team buys only one brand, but it’s not easy to get all sizes.
✔ Explanation: When joining two independent clauses with a coordinating conjunction (like “but”), you need a comma before the conjunction. “Our track team buys only one brand” and “it’s not easy to get all sizes” are both complete sentences.
---
4. My brother always wants the latest, greatest style of shoe.
✔ Explanation: “Latest” and “greatest” are coordinate adjectives — they both independently modify “style.” When two or more adjectives before a noun can be separated by “and” or reversed without changing meaning, they should be separated by a comma. (“latest and greatest” → correct; “greatest latest style” → sounds odd, but still acceptable — so comma is appropriate.)
---
5. He plays basketball, he plays tennis, and he runs track.
✔ Explanation: This is a compound sentence with three independent clauses joined by commas and a conjunction. Each clause could stand alone: “He plays basketball,” “He plays tennis,” and “He runs track.” Use commas to separate the clauses when using “and” before the last one.
*(Note: While grammatically correct, this sentence might be better rewritten for style: “He plays basketball, tennis, and runs track.” But since the instruction is to add commas as needed, we preserve the structure.)*
---
6. In fact, he has several pairs of sneakers for these sports.
✔ Explanation: “In fact” is a transitional phrase at the beginning of the sentence. Such phrases are usually followed by a comma to separate them from the main clause.
---
7. Since I jog almost every day, I am most concerned with the shoe’s comfort.
✔ Explanation: When a dependent clause (starting with “since”) comes before the main clause, you need a comma after the dependent clause. “Since I jog almost every day” sets up the reason for the main clause.
---
8. I do, however, shop for a style and color that I like.
✔ Explanation: “However” is a conjunctive adverb used for contrast. When placed in the middle of a sentence, it should be set off by commas on both sides.
---
9. Dark blue, my favorite color, is always my first choice.
✔ Explanation: “My favorite color” is a nonrestrictive appositive — it adds extra information about “Dark blue” but isn’t essential to the meaning. Nonrestrictive elements must be set off by commas.
---
10. This sale on athletic shoes ends August 31, 2009.
✔ Explanation: When writing a full date (month + day + year), you must place a comma between the day and the year. “August 31, 2009” is the correct format.
