What Does “Ago” Mean in English?
Ago is a word we use to talk about time in the past. It helps us count back from the present moment.
Think of it as meaning “before now.” It tells you how long before today something happened.
- It always refers to an action or event that is completely finished.
- It helps you answer questions like When did it happen?
How Do We Use "Ago" with the Past Simple?
We always use ago with the Past Simple tense. The structure is very important:
- First, use a verb in the Past Simple.
- Then, add a time expression (e.g., two hours, a week, many years).
- Finally, add the word ago.
Look at this pattern:
- Subject + Past Simple verb + time expression + ago.
When Should I Use "Ago"?
使用 ago when you want to specify a point in time in the past, counting backwards from now.
- Use it for actions that started and finished at a specific time in the past.
- It answers questions such as When did you last see a film? 或 How long ago did you move?
- It gives a clear reference point in the past relative to the present moment.
“Ago” vs. “For”: What's the Difference?
It's easy to confuse ago 和 for because both talk about time. However, they are used differently:
- Ago: Used with the Past Simple. It tells you when an action *finished*. It counts back from now. Example: I started this course three months ago. (The starting action finished three months before now.)
- For: Often used with the Present Perfect. It tells you the *duration* of an action that *continues up to now*. Example: I have studied English for three months. (I started three months ago and I am still studying.)
