A time clause helps show when one event happens relative to another.
The idea
Before introduces the later event; the other event happens first. After introduces the earlier event. Either clause can come first; use a comma after an opening time clause. For a future event, use a present form in the time clause.
Examples
- I wash my hands before I cook.
- After the rain stopped, we went outside.
- She checks the map before she leaves.
- We rested after we painted the room.
- Before the film begins, turn off your phone.
- He called after the train arrived.
