Place an event in the past with a clear time expression.

The idea

Use yesterday for the day before today, and last week or last night for a previous period. Put ago after a length of time: two hours ago means two hours before now. These expressions commonly accompany the past simple: We visited a museum last week.

Examples

  • I called my aunt yesterday.
  • We visited a museum last week.
  • They arrived two hours ago.
  • The shop closed last night.
  • I moved here three years ago.
  • She cooked dinner yesterday evening.

Watch out

Do not put ago before the number: say two hours ago, not ago two hours. These expressions locate an event; they do not themselves show how long it lasted.
