Ago: The Past Simple's Best Friend (Measured from NOW)
'Ago' is an adverb used to refer to a period of time that has passed *before the present moment*. It is almost exclusively used with the Simple Past tense to describe completed actions.
- âĻ Rule 1: Always from NOW: 'Ago' always counts time backward from the *current moment*. It answers 'How long before now?' Example: She finished her project three days ago. (Meaning: three days before *today*).
- âĻ Rule 2: Simple Past Tense Only: 'Ago' is almost always used with the Simple Past tense. It signals a definite past time. Example: We moved to this city five years ago. (Not: We *have moved* five years ago).
- âĻ Rule 3: Structure: [Duration of time] + ago. Example: A week ago, I saw him.
Identify the error in the following sentence: "She has visited Paris two years ago, but she doesn't remember much."
