Show Answer Key & Explanations Step-by-step solution for: Simple Compound, & Complex Sentences worksheet
Here's the solution to the worksheet, with explanations for each sentence:

---

1. Do you want to go to the park?
Simple sentence

*Explanation:* This sentence has only one independent clause — one subject (“you”) and one verb (“want”). It does not contain any coordinating conjunctions (FANBOYS) or subordinating conjunctions (AAAWWUBBIS). It’s a straightforward question.

---

2. While Max was at recess, he fell and hurt his knee.
Complex sentence

*Explanation:* The word “While” is a subordinating conjunction (from AAAWWUBBIS). It introduces a dependent clause: “While Max was at recess.” The main clause is “he fell and hurt his knee.” One dependent + one independent clause = complex sentence.

---

3. Do you have a dog, or do you have a cat?
Compound sentence

*Explanation:* The word “or” is a coordinating conjunction (from FANBOYS). It connects two independent clauses: “Do you have a dog?” and “Do you have a cat?” Each can stand alone as a complete sentence. Two independent clauses joined by a comma + FANBOYS = compound sentence.

---

4. My mom packed me an apple for lunch.
Simple sentence

*Explanation:* One subject (“My mom”), one verb (“packed”), and no conjunctions joining multiple clauses. It’s a single, complete thought.

---

5. My favorite subject is reading because I love good books.
Complex sentence

*Explanation:* “Because” is a subordinating conjunction (AAAWWUBBIS). It introduces the dependent clause “because I love good books.” The main clause is “My favorite subject is reading.” So, this is a complex sentence.

---

6. Maria wanted to go to school, but she was sick.
Compound sentence

*Explanation:* “But” is a coordinating conjunction (FANBOYS). It joins two independent clauses: “Maria wanted to go to school” and “she was sick.” Each could stand alone → compound sentence.

---

7. I hope I do well on my test!
Simple sentence

*Explanation:* Although it looks like it has two verbs (“hope” and “do”), “I do well on my test” is actually a noun clause acting as the object of “hope.” The whole thing is one independent clause with one main subject and verb. No conjunctions connecting separate clauses → simple sentence.

*(Note: Some might argue this is complex because “I do well…” is a subordinate clause, but in elementary grammar worksheets like this, it’s typically classified as simple since there’s no coordinating or subordinating conjunction explicitly joining clauses.)*

---

8. I feed my dog before I leave.
Complex sentence

*Explanation:* “Before” is a subordinating conjunction (AAAWWUBBIS). It introduces the dependent clause “before I leave.” The main clause is “I feed my dog.” One independent + one dependent clause = complex sentence.

---

9. I woke up early, and I am dressed for school.
Compound sentence

*Explanation:* “And” is a coordinating conjunction (FANBOYS). It joins two independent clauses: “I woke up early” and “I am dressed for school.” Both are complete sentences → compound sentence.
