Worksheet for practicing the future perfect tense with fill-in-the-blank exercises and sentence formation tasks.

Let’s go step by step to fill in the blanks using the future perfect tense.

The future perfect tense is made with:
will have + past participle of the verb.

We use it to talk about something that will be finished before a certain time in the future.

1. Harry will have studied (study) for 12 years when he graduates.
→ Already done as an example. “Studied” is the past participle of “study”.

2. Our team _______________ (finish) our season by September.
→ “Finish” → past participle = “finished”
→ Answer: will have finished

3. Her sister _______________ (do) research before writing her essay.
→ “Do” → past participle = “done”
→ Answer: will have done

4. The dog _______________ (sleep) for 6 hours by the time I got home.
Wait — this says “by the time I got home” — that’s past tense! But we’re practicing *future* perfect. Let’s check the sentence again.

Actually, looking at the context, maybe it should say “by the time I get home” (future). Since the worksheet is about future perfect, we’ll assume it’s meant to be future. So:

→ “Sleep” → past participle = “slept”
→ Answer: will have slept

*(Note: If it really says “got”, then it’s not future — but since the whole sheet is future perfect, we treat it as a typo and use future.)*

5. By Sunday, my parents _______________ (paint) the whole house.
→ “Paint” → past participle = “painted”
→ Answer: will have painted

6. I _______________ (clean) everything before my brother wakes up.
→ “Clean” → past participle = “cleaned”
→ Answer: will have cleaned

7. We _______________ (learn) a lot by the end of the year.
→ “Learn” → past participle = “learned” (or “learnt” — both okay, but “learned” is more common in US English)
→ Answer: will have learned

8. The horse _______________ (leave) the barn by now if the gate was open.
Again — “by now” and “was open” sound like present or past. But since this is future perfect practice, let’s assume it means “by [some future time]” — perhaps “by now” is meant to be “by then” or similar. Or maybe it’s conditional? Hmm.

But look — the structure still fits future perfect if we imagine: “The horse will have left the barn by [a future point] if the gate had been open.” But the sentence says “was open” — which is simple past.

This one is tricky. Maybe it’s testing whether you notice the mismatch? But since all others are straightforward future perfect, and this is likely a small error, we’ll go with:

→ “Leave” → past participle = “left”
→ Answer: will have left

*(In real grammar, this sentence might need rewording — but for this exercise, we follow the pattern.)*

Now, the last part: “Now try on your own”

1. Form a sentence using the future tense.
Example: I will walk to school tomorrow.

2. Form a sentence using the future perfect tense.
Example: She will have baked the cake by 5 PM.
