Printable worksheet helping students practice correct time prepositions like 'at', 'in', and 'on' through sentence completion.

Explanation:
Let’s go through each sentence one by one and choose the correct time expression from the list:
at / in / on / until / after / before / around / late / early

1. *I don’t like to wake up very _____ in the morning. I hate waking up before 8:00 am.*
→ The second sentence says “before 8:00 am”, so the first part implies waking up very early (since they hate waking *before* 8, they dislike being *early*).
✔ early

2. *I start work _____ 7 o’clock in the morning.*
→ Specific time (7 o’clock) → use at.
✔ at

3. *I go to bed _____ 10:00 pm.*
→ Again, specific time → at.
✔ at

4. *I stay up _____ midnight on Fridays.*
→ “Stay up” means continuing until a certain time — “until midnight” is natural.
✔ until

5. *I spend time with my family _____ weekends.*
→ Days of the week (weekends) → use on.
✔ on

6. *I like to exercise _____ 7:00 pm.*
→ Specific time → at.
✔ at

7. *I don’t eat anything _____ night.*
→ General time of day: *at night* is the standard phrase, but “at” is not in the box! Wait — options are: at / in / on / until / after / before / around / late / early.
“at night” is usual, but “at” is available. However, the blank is before “night”, and the phrase is “______ night”. In English, we say at night, but since “at” is listed and fits, it should be used. BUT — let’s double-check: Is there any better option?
- “in night” ✘ (not correct)
- “on night” ✘
- “after night” ✘
So only at works.
✔ at

Wait — hold on! In many grammar exercises for learners, they sometimes expect at night even if “at” seems reused. Since “at” is allowed multiple times (the instruction says some can be used more than once), it’s fine.

8. *I don’t like to do anything _____ weekends.*
→ Same as #5: weekends → on.
✔ on

9. *Do you go to bed _____ or late?*
→ The pair is “early or late”, common contrast. So blank = early.
✔ early

10. *I usually go to the cinema _____ at night.*
→ “_____ at night” — this is tricky. We don’t say “around at night” or “after at night”. Actually, the phrase is likely *around* night? No. Let’s read: “I usually go to the cinema _____ at night.” That sounds odd. Maybe it's “I usually go to the cinema around night”? But we say “around bedtime” or “around 9”, not “around night”.
Alternative: maybe it's late? “go to the cinema late at night” — yes! “late at night” is a common phrase. So blank = late.
✔ late

11. *I have to do a test _____ Saturday morning.*
→ Specific day + part of day → on (e.g., on Saturday morning).
✔ on

12. *It is very _____; I need to go home now because I have to wake up early tomorrow.*
→ Reason: need to wake up early → so it must be late (it’s late now).
✔ late

13. *What do you like to do _____ the afternoons?*
→ General time period: *in the afternoons* (we say “in the morning/afternoon/evening”).
✔ in

14. *I have to wait _____ midnight for you. Why didn’t you come before?*
→ Waiting *until* midnight is correct. “Wait until…” is standard.
✔ until

15. *I have to go _____ 11:00 pm. I cannot stay a minute after that time.*
→ Specific time → at.
✔ at

Now let’s list all answers in order:

1. early

7. at
8. on
9. early
10. late
11. on

Double-check #7: “I don’t eat anything at night.” — Yes, correct.
#10: “late at night” — yes, standard.

All fit.
