At, on, and in are three of the most common prepositions in English — but they cover both time and place uses, and a number of fixed idiomatic expressions on top of that. This exercise practices all of these together.
Grammar reviewAt, on, in — time and place
At, on, and in are used for both time and place expressions. The same size-based logic applies to both.
For TIME: at = specific point: at 3 PM, at noon, at night, at Christmas on = days and dates: on Monday, on 12 June, on my birthday in = longer periods: in March, in 2010, in summer, in the morning
For PLACE: at = a specific point or location: at the door, at the bus stop, at school, at home, at work on = a surface or line: on the table, on the wall, on the left, on page 5, on the bus/train in = inside an enclosed space or area: in the room, in a city, in France, in the car, in bed
Tricky fixed expressions: at the end (of a period or list) • in the end (eventually, after all) on time (punctual) • in time (not too late) at first (initially) • at last (finally)
