Compound Complex Sentences Practice Exercises | PDF | Syntax ... - Free Printable

Let's solve both practice exercises step by step. We'll first tackle Practice Exercise 1, where we combine simple sentences into compound sentences using coordinating conjunctions (e.g., *and, but, or, so, for, yet, nor*). Then, we’ll move to Practice Exercise 2, where we identify independent and subordinate clauses and classify the sentence as complex or compound-complex.

✔ Practice Exercise 1: Combine Simple Sentences into Compound Sentences

We will use coordinating conjunctions to join two independent clauses.

1. It rained for three days. The streets in my neighborhood flooded.
→ *It rained for three days, and the streets in my neighborhood flooded.*

2. I got to ball practice late. I forgot to set my alarm.
→ *I got to ball practice late because I forgot to set my alarm.*
*(Note: This is a complex sentence. But since the instruction asks for a compound sentence, we should use a coordinating conjunction.)*
→ *I got to ball practice late, and I forgot to set my alarm.*

3. Kyle completed his homework. He put it in his binder.
→ *Kyle completed his homework, and he put it in his binder.*

4. Luke mowed the lawn. He earned ten dollars.
→ *Luke mowed the lawn, and he earned ten dollars.*

5. I stayed up late last night. I am tired today.
→ *I stayed up late last night, so I am tired today.*

6. Neil doesn't like seafood. He doesn't like cabbage.
→ *Neil doesn't like seafood, and he doesn't like cabbage.*

7. My pencil was broken. I borrowed one from Jake.
→ *My pencil was broken, so I borrowed one from Jake.*

8. I like apples. I like pears more.
→ *I like apples, but I like pears more.*

9. Eight people got into the elevator. It was crowded. Three people got off.
→ *Eight people got into the elevator, and it was crowded; then three people got off.*
*(This combines three ideas. Since compound sentences typically have two independent clauses, we can split this into two parts or use a semicolon with a coordinating conjunction.)*
→ *Eight people got into the elevator, and it was crowded, so three people got off.*

10. Georgia gathered the pictures. She could arrange them in a special album for her family.
→ *Georgia gathered the pictures, and she could arrange them in a special album for her family.*

> ✔ Summary of Practice Exercise 1: All combined using coordinating conjunctions (mostly "and" or "so") to form compound sentences.

✔ Practice Exercise 2: Identify Clauses & Classify Sentence Type

We need to:
- Identify independent clauses (can stand alone).
- Identify subordinate clauses (depend on another clause).
- Determine if the sentence is complex (one independent + one subordinate) or compound-complex (two or more independent clauses + at least one subordinate).

11. Jason decided to stay up late because he had a lot of homework to do.
- Independent: *Jason decided to stay up late*
- Subordinate: *because he had a lot of homework to do*
→ Complex sentence

12. If you hurry, we might get to school on time.
- Subordinate: *If you hurry*
- Independent: *we might get to school on time*
→ Complex sentence

13. Although Monica had a cold, she went to school because she had a test.
- Subordinate: *Although Monica had a cold*
- Independent: *she went to school*
- Subordinate: *because she had a test*
→ Two subordinate clauses, one independent → Complex sentence
*(Note: Multiple subordinate clauses don’t make it compound-complex unless there are multiple independent clauses.)*

14. While washing the car, Todd slipped on the soap and he fell.
- Subordinate: *While washing the car* (participial phrase – not a full clause)
- Independent: *Todd slipped on the soap*
- Independent: *he fell*
→ Two independent clauses connected by *and*, plus a participial phrase.
→ Compound sentence (but note: “While washing…” is not a subordinate clause, just a phrase).
→ However, since "while" introduces a dependent clause only if it has a subject and verb. Here, "washing" lacks a subject — so it's a phrase, not a clause.
→ So: two independent clauses → Compound sentence

15. Dad takes the train to work even though he has a car.
- Independent: *Dad takes the train to work*
- Subordinate: *even though he has a car*
→ Complex sentence

16. After Mom arrived, she put the disk in the DVD player and we watched a great movie.
- Subordinate: *After Mom arrived*
- Independent: *she put the disk in the DVD player*
- Independent: *we watched a great movie*
→ One subordinate + two independent clauses → Compound-complex sentence

17. Even though his heart pounded with dread, Ben bolted up the stairs, and he checked out the strange noise.
- Subordinate: *Even though his heart pounded with dread*
- Independent: *Ben bolted up the stairs*
- Independent: *he checked out the strange noise*
→ One subordinate + two independent → Compound-complex sentence

18. Molly baked brownies since she had nothing else to do.
- Independent: *Molly baked brownies*
- Subordinate: *since she had nothing else to do*
→ Complex sentence

19. Karen made a list of what was needed, and she double-checked it so she wouldn't forget anything.
- Independent: *Karen made a list of what was needed*
- Independent: *she double-checked it*
- Subordinate: *so she wouldn't forget anything*
→ Two independent + one subordinate → Compound-complex sentence

20. Frank had a good sense of humor, so he laughed a lot.
- Independent: *Frank had a good sense of humor*
- Independent: *he laughed a lot*
→ Connected by *so* → Compound sentence

🔍 Key Concepts Recap:

- Independent clause: Can stand alone as a complete sentence.
- Subordinate clause: Begins with a subordinating conjunction (e.g., *because, although, while, since*) and cannot stand alone.
- Compound sentence: Two independent clauses joined by a coordinating conjunction (*and, but, or, so, for, yet, nor*) or a semicolon.
- Complex sentence: One independent + one or more subordinate clauses.
- Compound-complex sentence: Two or more independent clauses + at least one subordinate clause.
