Question

They (study) English for/since three months​

Answer 1

Ответ:

The correct verb form to use depends on whether the action of studying English is still ongoing or has already finished.

If the action is still ongoing, we should use the present perfect continuous tense, as follows:

"They have been studying English for three months."

If the action has already finished, we should use the past simple tense, as follows:

"They studied English for three months."

If we want to emphasize the duration of the action and imply that it is ongoing, we could use "since" instead of "for", as follows:

"They have been studying English since three months ago."
