Compound Sentences Worksheet - Top Teacher - Free Printable

Let's solve this Compound Sentences worksheet step by step. The goal is to choose the correct compound word (also called a coordinating conjunction or conjunctive adverb) from the given list to connect two independent clauses in each sentence.

Given Words:

- for
- so
- yet
- and
- or
- unless
- however
- because
- but
- after

---

Now, let’s go through each sentence and pick the best connecting word based on meaning and grammar.

---

1. I bought an apple, __________ I bought a pear.

- Both actions are similar and happen together.
- Best choice: and
✔ Answer: *and*

> "I bought an apple, and I bought a pear."

---

2. I missed the bus, __________ I walked to the park.

- The second action is a result of the first.
- Best choice: so
✔ Answer: *so*

> "I missed the bus, so I walked to the park."

---

3. Sam will miss the bus, __________ she finds her keys.

- This shows a condition: if she doesn't find her keys, she’ll miss the bus.
- Best choice: unless
✔ Answer: *unless*

> "Sam will miss the bus, unless she finds her keys."

---

4. Sally is famous, __________ she is very humble.

- There's a contrast between being famous and being humble.
- Best choice: but or however
- But note: “however” is usually set off with commas and often used mid-sentence.
- Here, it's placed between two clauses, so but fits better.
✔ Answer: *but*

> "Sally is famous, but she is very humble."

(Alternatively, “however” could work, but it would need punctuation: “Sally is famous; however, she is very humble.” — not ideal here.)

So, but is best.

---

5. James said no __________ he didn’t want to go.

- The reason he said no is that he didn’t want to go.
- Best choice: because
✔ Answer: *because*

> "James said no because he didn’t want to go."

---

6. We went to buy shoes, __________ the car broke down.

- A contrast: we had a plan, but something unexpected happened.
- Best choice: but
✔ Answer: *but*

> "We went to buy shoes, but the car broke down."

---

7. I eat carrots, __________ a snack before dinner.

- This seems like a missing subject/verb. It should be:
"I eat carrots, __________ a snack before dinner."
But likely meant to be: "I eat carrots, as a snack before dinner."
Wait — none of the words fit perfectly here.

Wait! Let's re-read:
“I eat carrots, __________ a snack before dinner.”

Hmm — maybe it's missing a verb? Or perhaps it's trying to say:
“I eat carrots, for a snack before dinner.”

Ah! Yes — for makes sense as a preposition.

So:
"I eat carrots for a snack before dinner."

✔ Answer: *for*

---

8. The gym is closed, __________, we can go to the beach.

- This has a comma after the blank — suggesting a pause and contrast.
- Best choice: however
✔ Answer: *however*

> "The gym is closed, however, we can go to the beach."

Note: “however” is typically surrounded by commas when used mid-sentence.

---

9. We can play, __________ we can have ice-cream.

- Two options: either play or have ice cream.
- Best choice: or
✔ Answer: *or*

> "We can play, or we can have ice-cream."

---

10. You can play __________ you have finished your homework.

- This shows a condition: only after finishing homework.
- Best choice: after
✔ Answer: *after*

> "You can play after you have finished your homework."

---

✔ Final Answers:

1. and
2. so
3. unless
4. but
5. because
6. but
7. for
8. however
9. or
10. after
