Question

I (to be) on a bus. present perfect or past simple​

Answer 1

Зависит от контекста. Но present perfect используется когда действие закончилось в прошлом и важен результат в настоящем, а past simple - это законченное действие в прошлом, которое не имеет никакого отношения к настоящему. Поэтому если в контексте нет никакой информации о том, что действие не дало никакого результата в настоящем, просто тупо закончилось и всё, то это будет past simple, т. е. I was on the bus.

Answer 2

The correct tense to use in this sentence depends on the context and the timing of the action.

1. If you are currently on the bus and you want to emphasize that fact, you should use the present perfect tense: "I have been on a bus."

2. If you are no longer on the bus and you want to talk about a specific past event, you should use the past simple tense: "I was on a bus."

So, to choose between present perfect and past simple, you need to consider whether you are still on the bus (present perfect) or if you are talking about a past event when you were on the bus (past simple).
