Worksheet on complex sentences with subordinating conjunctions for language learning.

Let me work through each sentence carefully to find the correct subordinating conjunction.

The options are: where, if, because, while, unless, whereas, till, after

1) Terry told us about the incident _______ we had reached the place.
- This needs a time-related conjunction. "after" makes sense - Terry told us after we arrived.
- Answer: after

2) Ross took care of our garden _______ we were away.
- This needs a time-related conjunction showing duration. "while" fits perfectly - during the time we were away.
- Answer: while

3) I thought Kia is a rude person, _______ in fact she is very kind.
- This shows contrast. "whereas" is used to show contrast between two ideas.
- Answer: whereas

4) _______ there is a will, there is a way.
- This is a famous saying/proverb. The standard form is "Where there is a will, there is a way."
- Answer: Where

5) _______ you wish to join the club, please fill this form.
- This is a conditional statement. "If" makes sense here.
- Answer: If

6) _______ you are very fit, you should not embark on mountaineering.
- This seems like it needs a conditional that means "even though" or a negative condition. Looking at the options... "Unless" could work but doesn't quite fit. Let me reconsider.
- Actually, this might need "Although" but that's not an option.
- Wait, let me re-read: "_______ you are very fit, you should not embark on mountaineering."
- Hmm, this is tricky. None of the given options seem to fit perfectly. But looking again at the context and available options...
- Actually, I think there might be an issue with this sentence as written. But among the options, perhaps it's meant to be read differently. Let me consider if "unless" works: "Unless you are very fit, you should not embark on mountaineering" - this makes sense! It means if you're not very fit, don't go mountaineering.
- Answer: Unless

7) We waited at the airport _______ the flight took off.
- This needs a time conjunction. "till" (until) makes sense - we waited until the flight departed.
- Answer: till

8) Jake didn't play today _______ he had a toe injury.
- This needs a reason/conjunction. "because" explains why he didn't play.
- Answer: because

Let me verify all answers use different conjunctions from the list:
- where ✓ (used in #4)
- if ✓ (used in #5)
- because ✓ (used in #8)
- while ✓ (used in #2)
- unless ✓ (used in #6)
- whereas ✓ (used in #3)
- till ✓ (used in #7)
- after ✓ (used in #1)

All 8 conjunctions are used exactly once. Perfect!

Final Answer:
1) after
2) while
3) whereas
4) Where
5) If
6) Unless
7) till
8) because
