Educational worksheet for identifying sentence types: simple, compound, or complex.

Let’s go through each sentence one by one and figure out if it’s simple, compound, or complex.

---

Quick reminder (for you, not part of final answer):

- Simple sentence: One complete thought. Has a subject and verb. No joining words like “and”, “but”, “because”, etc., that connect two full sentences.
- Compound sentence: Two simple sentences joined together with words like “and”, “but”, “so”, “or”. Both parts could stand alone as their own sentences.
- Complex sentence: One main idea + one extra piece that can’t stand alone (starts with words like “when”, “after”, “before”, “because”, “if”, etc.).

Now let’s solve:

1. We have to go to bed when the clock chimes ten o’clock.
→ Main part: “We have to go to bed”
→ Extra part: “when the clock chimes ten o’clock” → this can’t stand alone → so it’s complex

2. Jennifer liked William’s friend, and she also liked his cousin.
→ First part: “Jennifer liked William’s friend” → complete
→ Second part: “she also liked his cousin” → also complete
→ Joined by “and” → so it’s compound

3. The big brown dog ran after the blue and red ball.
→ Only one action, one subject (“dog”), no joining words connecting two full ideas → simple

4. James and Eve rode their bicycles after they ate lunch.
→ Main: “James and Eve rode their bicycles”
→ Extra: “after they ate lunch” → starts with “after” → can’t stand alone → complex

5. The teacher and the principal met in the hall near the library.
→ One subject group (“teacher and principal”) doing one thing → still just ONE complete thought → simple

6. Many brave soldiers fought in the war, but they received medals.
→ First: “Many brave soldiers fought in the war” → complete
→ Second: “they received medals” → complete
→ Joined by “but” → compound

7. The drummers played a long time, but the piano players stopped early.
→ First: “The drummers played a long time” → complete
→ Second: “the piano players stopped early” → complete
→ Joined by “but” → compound

8. Before the queen rode in the parade, she gave a speech.
→ Starts with “Before...” → that’s an extra clause
→ Main: “she gave a speech”
→ So it’s complex

9. After midnight the ghosts will come out of the haunted attic.
→ “After midnight” is just a time phrase — doesn’t have its own subject+verb → whole thing is one complete thought → simple

Wait — let me double-check #9:
“After midnight” = prepositional phrase (not a clause)
“The ghosts will come out...” = main clause
No second clause → so yes, simple

10. She dropped the pan and the plate, but she held on to the spoon.
→ First: “She dropped the pan and the plate” → complete
→ Second: “she held on to the spoon” → complete
→ Joined by “but” → compound
