Step-by-step solution for: Time Conjunctions interactive worksheet
Let's solve this exercise step by step. The task is to fill in the blanks with the correct time conjunctions from the list:
> Once, until, before, after, while, as soon as, when
We need to choose the most appropriate conjunction for each sentence based on the meaning and timing of the actions.
---
- "When" or "as soon as" could work, but "when" is more natural here.
- It means: He will light the fire at the time it becomes dark.
- ✔ When it gets dark, he’ll light the fire.
---
- This indicates a future action that will happen after leaving work.
- "After" makes sense: calling happens after leaving.
- ✔ I’ll call you after I leave work.
---
- This describes two actions happening at the same time, possibly in sequence.
- "While" suggests simultaneous actions.
- ✔ I watered the plants while my husband mowed the lawn.
---
- This implies he came after everyone else left.
- So, "after" fits best.
- ✔ He arrived after everybody had gone home.
---
- This means repayment will happen once the item is sold.
- "Once" or "when" both possible, but "once" emphasizes completion.
- ✔ You can repay me once it’s sold.
---
- This refers to a period of time up to retirement.
- "Until" is used for a duration ending at a point in time.
- ✔ He was the headteacher until he retired in 1998.
---
- This is advice to think before making a decision.
- "Before" is logical: think carefully before choosing.
- ✔ Think very carefully before you choose.
---
- This phrase is fixed: "as soon as".
- ✔ I promise to tell you my results as soon as I get them.
---
- This shows an action done during another action.
- "While" is used for ongoing actions happening at the same time.
- ✔ I read the newspaper while I was waiting for the kettle to boil.
---
- This means we will go out after the rain stops.
- "After" or "when" — but "after" emphasizes the sequence.
- However, "when" is also acceptable.
- But since it's conditional, "when" is better: “We'll go outside when it has stopped raining.”
- ✔ We’ll go outside when it has stopped raining.
---
- This is a condition: once the exams are passed, qualification follows.
- "Once" is perfect here.
- ✔ Once I pass all my exams, I’ll be fully qualified.
---
- This means the movie ended at or after 11pm.
- "Until" is used to show continuation up to a point.
- "The movie didn’t finish until 11pm" = it finished at 11pm.
- ✔ The movie didn’t finish until 11pm.
---
- This means the run happened before breakfast.
- ✔ I went for a run before breakfast.
---
- This suggests Kevin called during the time you were leaving.
- "While" indicates simultaneity.
- ✔ Kevin phoned me while you left.
> Note: "while" is used with continuous actions. "You left" is simple past, but in context, it may imply a short period. Alternatively, "as" could work, but "while" is acceptable here if we assume the action took some time.
But actually, "when" is often used for shorter events:
- "Kevin phoned me when you left." – also acceptable.
However, since the options include "while", and it's commonly used for such contexts (e.g., “I was sleeping while you were cooking”), let’s stick with:
✔ while — assuming the act of leaving took time.
But technically, "when" is better for instantaneous events.
So, "when" is more accurate here.
➡️ Kevin phoned me when you left.
