'Ago' refers to a finished point in time; 'since' refers to a period of time starting in the past and continuing to the present.

使用说明

The word 'ago' must always follow the time expression (e.g., 'ten minutes ago', not 'ago ten minutes'). It is primarily used with the Past Simple tense, not the Present Perfect.

⚠️

常见错误

Learners often mistakenly use 'ago' with the Present Perfect tense, saying 'I have seen him two days ago' instead of 'I saw him two days ago.'
