Adverbial clauses worksheet focusing on "before," "after," and "when" with sentence completion and matching exercises.

Let’s solve each part step by step.

---

Part 1: Complete the sentences with before, after, or when.

We need to pick the right word based on the timing of events.

1. When Carlos had a birthday, we threw him a surprise party.
→ Already done as example. “When” means at the same time — the party happened *at the time* of his birthday.

2. ______ He came to the door, we all shouted, “Surprise!”
→ The shouting happened *right at the moment* he arrived. So it’s simultaneous → When

3. We sang “Happy Birthday” ______ he blew out the candles.
→ Usually, you sing *before* blowing out candles. So → before

4. ______ He opened his gifts, he sent thank-you cards.
→ You send thank-you cards *after* opening gifts. So → After

✔ Part 1 Answers:
2. When
3. before
4. After

Part 2: Match the information to make complete sentences.

We match left side (1–6) with right side (a–f) so the sentence makes logical sense.

1. When I have a problem, e → already matched: “I talk to my best friend.” Makes sense.

2. I felt really angry ___
→ Look for something that would make someone angry. Option a) “after I read her terrible email.” → Yes, reading a bad email can make you angry.

3. I try to look good ___
→ Why do people try to look good? Often before going somewhere nice. Option b) “when I go to a party.” → Perfect fit.

4. Before I went home, ___
→ What might you do before going home? Maybe buy something. Option f) “I bought some flowers.” → Logical.

5. After I left your party, ___
→ After leaving one party, maybe you went to another. Option c) “I went to another one!” → Fits.

6. I don’t eat breakfast ___
