Why do we use Past Simple Tense?
Besides definite past aspect, the completion aspect is the key in Past simple and it helps us to use it appropriately with different tenses. We use it to talk about completed actions in the past.
For example...
I finished my homework two minutes ago. It is on the teacher's desk now.
We drank two cups of tea in the morning. It's afternoon and we aren't drinking tea now.
For example... We went to a restaurant, called the waiter and ordered pizza for us. |
