Let’s go through each sentence one by one. We’re choosing between
at,
in, or
on — these are prepositions we use with time.
Here’s a quick guide to help you remember:
- Use
at for exact times (like 8:15, midnight, night).
- Use
on for days and dates (like Mondays, September 7th, the weekend).
- Use
in for months, years, seasons, and parts of the day (like June, the morning, the afternoon).
Now let’s solve each one:
1. Bernardo gets up ___ 8:15. → Exact time →
at
2. Fathers’ Day is ___ June. → Month →
in
3. I visit my grandmother ___ Mondays. → Day of week →
on
4. Our English class starts ___ 6:30. → Exact time →
at
5. I study my English books ___ the evening. → Part of day →
in
6. Linda finishes work ___ 5:45. → Exact time →
at
7. Leonardo’s birthday is ___ November. → Month →
in
8. That store isn’t open ___ Fridays. → Day of week →
on
9. Thanksgiving Day is ___ the fourth Thursday of November. → Specific day →
on
10. This bank opens ___ 7:00 ___ the morning. → Time + part of day →
at,
in
11. Teachers’ Day is ___ October. → Month →
in
12. The music shop closes ___ 8:30. → Exact time →
at
13. Halloween is ___ October. → Month →
in *(Note: Some might say “on” if thinking of Oct 31, but since it just says “October”, we use “in”)*
14. I sleep ___ midnight. → Exact time →
at
15. Simon goes to work ___ the afternoon. → Part of day →
in
16. Harry works ___ night. → Fixed phrase →
at
17. David doesn’t work ___ Saturdays and Tuesdays. → Days →
on
18. Robin goes to work ___ the morning ___ 8:00. → Part of day + time →
in,
at
19. His birthday is ___ September 7th. → Date →
on
20. My sister’s birthday’s ___ February 14th. → Date →
on
21. Ralph doesn’t go to work ___ Saturdays. → Day →
on
22. Mothers’ Day is ___ May. → Month →
in
23. April Fools’ Day is ___ April 1st. → Date →
on
24. I eat my breakfast ___ 7:15 every day. → Exact time →
at
25. Paul doesn’t go to work ___ the weekend. → Common phrase →
on
Wait — let’s double-check #13: “Halloween is ___ October.”
Halloween is always on October 31st, so technically it’s a specific date. But the sentence only says “October,” not “October 31st.” In grammar exercises like this, if only the month is given, we usually use
in. So we’ll stick with
in.
Also #25: “the weekend” → we say
on the weekend in American English. Some dialects use “at,” but standard school grammar teaches
on.
